This crashes the kernel in funny ways if the patching template is buggy, and usually in much later places. Instead do a direct BUG_ON(), there's no way to continue successfully at that point. I've tested this patch, with the vanilla kernel check never triggers, and if I intentionally increase the size of one of the patch templates to a too high value the assert triggers: [ 0.164385] kernel BUG at arch/x86/kernel/paravirt.c:167! Without this patch a broken kernel randomly crashes in later places, after the silent patching failure.

While clever this is falling apart with LTO and even aside of LTO the construct is just working by chance according to GCC folks. Aside of that the tables are constant data and not some form of magic text. As these constructs are not subject to frequent changes it is not a maintenance issue to convert them to regular data tables which are initialized with hex bytes. Create a new set of macros and data structures to store the instruction sequences and convert the code over.

ApolloLake, GeminiLake, CannonLake (and presumably all new chipsets from this point) report the crystal frequency directly via CPUID.0x15. That's definitive data that we can rely upon. 2. Skylake, Kabylake and all variants of those two chipsets report a crystal frequency of zero, however we can calculate the crystal clock speed by condidering data from CPUID.0x16. This method correctly distinguishes between the two crystal clock frequencies present on different Skylake X variants that caused headaches before. As the calculations do not quite match the previously-hardcoded values in some cases (e.g. 23913043Hz instead of 24MHz), TSC refinement is enabled on all platforms where we had to calculate the crystal frequency in this way. 3. Denverton (GOLDMONT_X) reports a crystal frequency of zero and does not support CPUID.0x16, so we leave this entry hardcoded.

On Intel SoCs, we believe that the APIC is fed by the crystal clock; this would make sense, and the crystal clock frequency has been verified against the APIC timer calibration result on ApolloLake, GeminiLake, Kabylake, CoffeeLake, WhiskeyLake and AmberLake. Set lapic_timer_period based on the crystal clock frequency accordingly. APIC timer calibration would normally be skipped on modern CPUs by nature of the TSC deadline timer being used instead, however this change is still potentially useful, e.g. if the TSC deadline timer has been disabled with a kernel parameter. calibrate_APIC_timer() uses the legacy timer, but we are seeing new platforms that omit such legacy functionality, so avoiding such codepaths is becoming more important.

At the time this was added, this was sound as: * Modifications to leaf entries could result in stale information being logged, but would not result in a functional problem. * Boot time modifications to non-leaf entries (e.g. freeing of initmem) were performed when the ptdump code cannot be invoked. * At runtime, modifications to non-leaf entries only occurred in the vmalloc region, and these were strictly additive, as intermediate entries were never freed. However, since commit: commit 324420bf91f6 ("arm64: add support for ioremap() block mappings") ... it has been possible to create huge mappings in the vmalloc area at runtime, and as part of this existing intermediate levels of table my be removed and freed. It's possible for the ptdump code to race with this, and continue to walk tables which have been freed (and potentially poisoned or reallocated). As a result of this, the ptdump code may dereference bogus addresses, which could be fatal. Since huge-vmap is a TLB and memory optimization, we can disable it when the runtime ptdump code is in use to avoid this problem.

charset=UTF-8 Content-Transfer-Encoding: 8bit Since commit 1e434b703248 ("ARM: imx: update the cpu power up timing setting on i.mx6sx") some characters loss is noticed on i.MX6ULL UART as reported by Christoph Niedermaier. The intention of such commit was to increase the SW2ISO field for i.MX6SX only, but since cpuidle-imx6sx is also used on i.MX6UL/i.MX6ULL this caused unintended side effects on other SoCs. Fix this problem by keeping the original SW2ISO value for i.MX6UL/i.MX6ULL and only increase SW2ISO in the i.MX6SX case.

The WiFi side identifies as BCM43430, while the Bluetooth side identifies as BCM43438. The Bluetooth side is connected to UART3 in a 4 wire configuration. Same as the WiFi side, due to being the same chip and package, DLDO1 and DLDO2 regulator outputs from the PMIC provide overall power via VBAT and I/O power via VDDIO. The CLK_OUT_A clock output from the SoC provides the LPO low power clock at 32.768 kHz. This patch enables Bluetooth on this board, and also adds the missing LPO clock on the WiFi side. There is also a PCM connection for Bluetooth, but this is not covered here. The LPO clock is fed from CLK_OUT_A, which needs to be muxed on pin PI12. This can be represented in multiple ways. This patch puts the pinctrl property in the pin controller node. This is due to limitations in Linux, where pinmux settings, even the same one, can not be shared by multiple devices. Thus we cannot put it in both the WiFi and Bluetooth device nodes. Putting it the CCU node is another option, but Linux's CCU driver does not handle pinctrl. Also the pin controller is guaranteed to be initialized after the CCU, when clocks are available. And any other devices that use muxed pins are guaranteed to be initialized after the pin controller. Thus having the CLK_OUT_A pinmux reference be in the pin controller node is a good choice without having to deal with implementation issues.

The WiFi side identifies as BCM43430, while the Bluetooth side identifies as BCM43438. WiFi is connected to mmc1 and the Bluetooth side is connected to UART1 in a 4 wire configuration. Same as the WiFi side, due to being the same chip and package, DLDO2 provides overall power via VBAT, and DLDO4 provides I/O power via VDDIO. The RTC clock output provides the LPO low power clock at 32.768 kHz. This patch enables WiFi and Bluetooth on OrangePi Win boards and adds missing LPO clock on the WiFi side. PCM connection also exists for Bluetooth audio, but it's not used here. Bluetooth UART speed is set to 1.5 MBaud in order to be able transmit audio. While module supports even higher speeds, currently sunxi clock driver doesn't support higher speed.

Try to work around that linking issue by moving the *.init and *.exit text segments closer to the main text segment. With that change those segments now don't get freed at runtime any longer, but since we in most cases run with huge-page enabled, we ignore the lost memory in preference of better performance. This change will not guarantee that every kernel config will now sucessfully build with short calls and without linking issues.

It turns out that the vendor kernel relies on the bootloader to set up the voltage. The bootloader however sets a fixed voltage of 1.10V.

The VDDEE regulator supplies the Mali GPU. It's basically a copy of the VCCK (CPU supply) which means it's limited to 0.86V to 1.14V. Update the operating voltage of the Mali GPU on Meson8b to 1.10V so it matches with what the vendor u-boot sets.

If code+umask were needed, then the INTEL_FLAGS_UEVENT_CONSTRAINT() macro was needed instead. This broke with some of the constraints for PEBS events. Several of them, including the one used for cycles:p, cycles:pp, cycles:ppp fell in that category and caused the event to be rejected in PEBS mode. In other words, on some platforms a cmdline such as: $ perf top -e cycles:pp would fail with -EINVAL. This patch fixes this bug by properly using INTEL_FLAGS_UEVENT_CONSTRAINT() when needed in the PEBS constraint tables.

Remove the ethernet-phy-id compatible string and add a comment with the PHY ID instead. This is a no-op on boards which are shipped with the PHY that was listed (= all known cases). However, if a board manufacturer decides to ship a different PHY we will now load and use the correct driver because we ask the PHY to identify itself.

Let's use this to provide the names for all the pins on rk3288-veyron-minnie. In general the names here come straight from the schematic. That means even if the schematic name is weird / doesn't have consistent naming conventions / has typos I still haven't made any changes. The exception here is for two pins: the recovery switch and the write protect detection pin. These two pins need to have standardized names since crossystem (a Chrome OS tool) uses these names to query the pins. In downstream kernels crossystem used an out-of-tree driver to do this but it has now been moved to the gpiod API and needs the standardized names. It's expected that other rk3288-veyron boards will get similar patches shortly. NOTE: I have sorted the "gpio" section to be next to the "pinctrl" section since it seems to logically make the most sense there.

Specifically on the rk3288 it can be seen that the timer stops ticking in suspend if we end up running through the "osc_disable" path in rk3288_slp_mode_set(). In that path the 24 MHz clock will turn off and the timer stops. To test this, I ran this on a Chrome OS filesystem: before=$(date); \ suspend_stress_test -c1 --suspend_min=30 --suspend_max=31; \ echo ${before}; date ...and I found that unless I plug in a device that requests USB wakeup to be active that the two calls to "date" would show that fewer than 30 seconds passed. NOTE: deep suspend (where the 24 MHz clock gets disabled) isn't supported yet on upstream Linux so this was tested on a downstream kernel.

There is a newer Netx 4000 architecture which we may see included at some point, but this will be supported using the standard multiplatform and devicetree mechanisms and is easier to develop from scratch.

While here, also give the regulator an alias as it supplies the Mali GPU so a phandle to it will be required later on.

Kbuild used to have a global restriction "no space after -I", but commit 48f6e3cf5bc6 ("kbuild: do not drop -I without parameter") got rid of it. Having a space after -I is no longer a big deal as far as Kbuild is concerned. It is still a big deal for MIPS because arch/mips/vdso/Makefile filters the header search paths, like this: ccflags-vdso := \ $(filter -I%,$(KBUILD_CFLAGS)) \ ..., which relies on the assumption that there is no space after -I .

In powerpc code we reuse a kexec_buf variable for loading both the kernel and the initramfs by resetting some of the fields between those uses, but not mem.

This reduces the size of the entries, but more importantly, it gets rid of statically assigned absolute addresses, which require fixing up at boot time if the kernel is self relocating (which takes a 24 byte RELA entry for each member of the ksymtab struct). Since ksymtab entries are always part of the same module as the symbol they export, it was assumed at the time that a 32-bit relative reference is always sufficient to capture the offset between a ksymtab entry and its target symbol. Unfortunately, this is not always true: in the case of per-CPU variables, a per-CPU variable's base address (which usually differs from the actual address of any of its per-CPU copies) is allocated in the vicinity of the ..data.percpu section in the core kernel (i.e., in the per-CPU reserved region which follows the section containing the core kernel's statically allocated per-CPU variables). Since we randomize the module space over a 4 GB window covering the core kernel (based on the -/+ 4 GB range of an ADRP/ADD pair), we may end up putting the core kernel out of the -/+ 2 GB range of 32-bit relative references of module ksymtab entries that refer to per-CPU variables. So reduce the module randomization range a bit further. We lose 1 bit of randomization this way, but this is something we can tolerate.

When CONFIG_KASAN is enabled for the kernel build but KASAN code generation is disabled for the compilation unit (which is needed for things like the EFI stub or the decompressor), the string routines are just #define'd to their __ prefixed names so that they are simply invoked directly. This does however rely on those __ prefixed names to exist in the symbol namespace, which is not currently the case for the x86 decompressor, which may lead to errors like drivers/firmware/efi/libstub/tpm.o: In function `efi_retrieve_tpm2_eventlog': tpm.c:(.text+0x2a8): undefined reference to `__memcpy' So let's expose the __ prefixed symbols in the decompressor when KASAN is enabled.

However it does not make much sense to create irqfd even without the kernel chips. Let's provide a arch-dependent helper to check whether a specific irqfd is allowed by the arch. At least for x86, it should make sense to check: - when irqchip mode is NONE, all irqfds should be disallowed, and, - when irqchip mode is SPLIT, irqfds that are with resamplefd should be disallowed. For either of the case, previously we'll silently ignore the irq or the irq ack event if the irqchip mode is incorrect. However that can cause misterious guest behaviors and it can be hard to triage. Let's fail KVM_IRQFD even earlier to detect these incorrect configurations.

So let's fix this by returning NULL from efi_call_phys_prolog() on memory allocation failures only, and by handling this condition in the caller. Also, clean up any half baked sets of page tables that we may have created before returning with a NULL return value. Note that any failure at this level will trigger a panic() two levels up, so none of this makes a huge difference, but it is a nice cleanup nonetheless.

These days it's completely pointless - dentries of pipes are not even connected to pipefs root. However, mount_pseudo() had set the root dentry name (passed as the second argument) and callers kept inventing names to pass to it. Including those that didn't *have* any non-root dentries to start with... All of that had been pointless for about 8 years now; it's time to get rid of that cargo-culting...

Biederman" Date: Thu, 16 May 2019 10:55:21 -0500 Subject: signal/arm64: Use force_sig not force_sig_fault for SIGKILL I don't think this is userspace visible but SIGKILL does not have any si_codes that use the fault member of the siginfo union. Correct this the simple way and call force_sig instead of force_sig_fault when the signal is SIGKILL. The two know places where synchronous SIGKILL are generated are do_bad_area and fpsimd_save. The call paths to force_sig_fault are: do_bad_area arm64_force_sig_fault force_sig_fault force_signal_inject arm64_notify_die arm64_force_sig_fault force_sig_fault Which means correcting this in arm64_force_sig_fault is enough to ensure the arm64 code is not misusing the generic code, which could lead to maintenance problems later.

And we need to do it before we enable the clock and after we disable it. Currently we are still relying on platform callbacks indirectly managing clockdomain autoidle. But I noticed that for device tree only probed drivers it now happens only after we enabling the clocks and before we disable the clocks, while it should be the other way around. So far I have not noticed any issues with this though. Let's add new ti_sysc_clkdm_deny_idle() and ti_sysc_clkdm_allow_idle() functions for ti-sysc driver to use to manage clockdomains directly via platform data callbacks. Note that we can implement the clockdomain functions in pdata-quirks.c as for probing devices without "ti,hwmods" custom property we don't need to use the other platform data callbacks. Let's do this in one patch as there's is still an unlikely chance we may need to apply this as a fix for v5.2 for dropping legacy platform data for some devices. We also do have the option of adding back the platform data if needed in case of trouble.

This fix introduces a workaround: The domain field of the request CPRB is checked if there is a valid domain value in there. If this is true and the value is a control only domain (a domain which is enabled in the crypto config ADM mask but disabled in the AQM mask) the CPRB is forwarded to the default usage domain. If there is no default domain, the request is rejected with an ENODEV. This fix is important for maintaining crypto adapters. For example one LPAR can use a crypto adapter domain ('Control and Usage') but another LPAR needs to be able to maintain this adapter domain ('Control'). Scenarios like this did not work properly and the patch enables this.

These tests showed that the current implementation of gcm-aes-s390 is not able to deal with chunks of output buffers which are not a multiple of 16 bytes. This patch introduces a rework of the gcm aes s390 scatter walk handling which now is able to handle any input and output scatter list chunk sizes correctly. Code has been verified by the crypto selftests, the tcrypt kernel module and additional tests ran via the af_alg interface.

As the ftrace ring buffer stores data on 4 byte alignment, this config option was used to force it to store data on 8 byte alignment to make sure the data being stored and written directly into the ring buffer was 8 byte aligned as it would cause issues trying to write an 8 byte word on a 4 not 8 byte aligned memory location. But with the removal of the metag architecture, which was the only architecture to use this, there is no architecture supported by Linux that requires 8 byte aligne access for all 8 byte words (4 byte alignment is good enough). Removing this config can simplify the code a bit.

However, on s390x, the amount of usable CPUs is determined during runtime - it is depending on the features of the machine the code is running on. Since we are using the vcpu_id as an index into the SCA structures that are defined by the hardware (see e.g. the sca_add_vcpu() function), it is not only the amount of CPUs that is limited by the hard- ware, but also the range of IDs that we can use. Thus KVM_CAP_MAX_VCPU_ID must be determined during runtime on s390x, too. So the handling of KVM_CAP_MAX_VCPU_ID has to be moved from the common code into the architecture specific code, and on s390x we have to return the same value here as for KVM_CAP_MAX_VCPUS. This problem has been discovered with the kvm_create_max_vcpus selftest. With this change applied, the selftest now passes on s390x, too.

However, the same code path is used for absolute relocations, where the interpretation is the opposite: the only current use case for absolute relocations operating on non-native word size quantities is the CRC32 handling in the CONFIG_MODVERSIONS code, and these CRCs are unsigned 32-bit quantities, which are now being rejected by the module loader if bit 31 happens to be set. So let's use different ranges for quanties subject to absolute vs. relative relocations: - ABS16/32 relocations should be in the range [0, Uxx_MAX) - PREL16/32 relocations should be in the range [Sxx_MIN, Sxx_MAX) - otherwise, print an error since no other 16 or 32 bit wide data relocations are currently supported.

However, future patches will change the mutex associated with kvm->arch.mmu_ready to a new mutex that nests inside the vcpu mutexes, making it difficult to continue to use this method. In fact, taking the vcpu mutex for a vcpu excludes execution of that vcpu, and we already take the vcpu mutex around the call to kvmppc_xive_[native_]cleanup_vcpu(). Once the cleanup function is done and we release the vcpu mutex, the vcpu can execute once again, but because we have cleared vcpu->arch.xive_vcpu, vcpu->arch.irq_type, vcpu->arch.xive_esc_vaddr and vcpu->arch.xive_esc_raddr, that vcpu will not be going into XIVE code any more. Thus, once we have cleaned up all of the vcpus, we are safe to clean up the rest of the XIVE state, and we don't need to use kvm->arch.mmu_ready to hold off vcpu execution.

However, this means that kvm->lock is being taken inside vcpu->mutex, which is contrary to Documentation/virtual/kvm/locking.txt and results in lockdep warnings. To fix this, we add a new mutex, kvm->arch.mmu_setup_lock, which nests inside the vcpu mutexes, and is taken in the places where kvm->lock was taken that are related to MMU setup. Additionally we take the new mutex in the vcpu creation code at the point where we are creating a new vcore, in order to provide mutual exclusion with kvmppc_update_lpcr() and ensure that an update to kvm->arch.lpcr doesn't get missed, which could otherwise lead to a stale vcore->lpcr value.

Because this list is scanned inside kvmppc_rtas_hcall(), which is called with the vcpu mutex held, taking kvm->lock cause a lock inversion problem, which could lead to a deadlock. To fix this, we add a new mutex, kvm->arch.rtas_token_lock, which nests inside the vcpu mutexes, and use that instead of kvm->lock when accessing the rtas token list. This removes the lockdep_assert_held() in kvmppc_rtas_tokens_free(). At this point we don't hold the new mutex, but that is OK because kvmppc_rtas_tokens_free() is only called when the whole VM is being destroyed, and at that point nothing can be looking up a token in the list.

However, that leads to a lock order inversion problem, because these are called in contexts where the vcpu mutex is held, but the vcpu mutexes nest within kvm->lock according to Documentation/virtual/kvm/locking.txt. Hence there is a possibility of deadlock. To fix this, we simply don't take the kvm->lock mutex around these calls. This is safe because the implementations of kvm_for_each_vcpu() and kvm_get_vcpu_by_id() have been designed to be able to be called locklessly.

Biederman" Date: Thu, 23 May 2019 11:11:19 -0500 Subject: signal/arm64: Use force_sig not force_sig_fault for SIGKILL I don't think this is userspace visible but SIGKILL does not have any si_codes that use the fault member of the siginfo union. Correct this the simple way and call force_sig instead of force_sig_fault when the signal is SIGKILL. The two know places where synchronous SIGKILL are generated are do_bad_area and fpsimd_save. The call paths to force_sig_fault are: do_bad_area arm64_force_sig_fault force_sig_fault force_signal_inject arm64_notify_die arm64_force_sig_fault force_sig_fault Which means correcting this in arm64_force_sig_fault is enough to ensure the arm64 code is not misusing the generic code, which could lead to maintenance problems later.

Biederman" Date: Wed, 6 Feb 2019 16:39:13 -0600 Subject: signal: Use force_sig_fault_to_task for the two calls that don't deliver to current In preparation for removing the task parameter from force_sig_fault introduce force_sig_fault_to_task and use it for the two cases where it matters. On mips force_fcr31_sig calls force_sig_fault and is called on either the current task, or a task that is suspended and is being switched to by the scheduler. This is safe because the task being switched to by the scheduler is guaranteed to be suspended. This ensures that task->sighand is stable while the signal is delivered to it. On parisc user_enable_single_step calls force_sig_fault and is in turn called by ptrace_request. The function ptrace_request always calls user_enable_single_step on a child that is stopped for tracing. The child being traced and not reaped ensures that child->sighand is not NULL, and that the child will not change child->sighand. Signed-off-by: "Eric W.

Biederman" Date: Thu, 23 May 2019 11:04:24 -0500 Subject: signal: Remove the task parameter from force_sig_fault As synchronous exceptions really only make sense against the current task (otherwise how are you synchronous) remove the task parameter from from force_sig_fault to make it explicit that is what is going on. The two known exceptions that deliver a synchronous exception to a stopped ptraced task have already been changed to force_sig_fault_to_task. The callers have been changed with the following emacs regular expression (with obvious variations on the architectures that take more arguments) to avoid typos: force_sig_fault[(]\([^,]+\)[,]\([^,]+\)[,]\([^,]+\)[,]\W+current[)] -> force_sig_fault(\1,\2,\3) Signed-off-by: "Eric W.

This is true iff the address provided is found within the unmapped address range between PAGE_OFFSET & MAP_BASE, but we don't currently check for that condition. Instead we simply mask the address to obtain what will be a physical address if the virtual address is indeed in the desired range, shift it to form a PFN & then call pfn_valid(). This can incorrectly return true if called with a virtual address which, after masking, happens to form a physical address corresponding to a valid PFN. For example we may vmalloc an address in the kernel mapped region starting a MAP_BASE & obtain the virtual address: addr = 0xc000000000002000 When masked by virt_to_phys(), which uses __pa() & in turn CPHYSADDR(), we obtain the following (bogus) physical address: addr = 0x2000 In a common system with PHYS_OFFSET=0 this will correspond to a valid struct page which should really be accessed by virtual address PAGE_OFFSET+0x2000, causing virt_addr_valid() to incorrectly return 1 indicating that the original address corresponds to a struct page. This is equivalent to the ARM64 change made in commit ca219452c6b8 ("arm64: Correctly bounds check virt_addr_valid"). This fixes fallout when hardened usercopy is enabled caused by the related commit 517e1fbeb65f ("mm/usercopy: Drop extra is_vmalloc_or_module() check") which removed a check for the vmalloc range that was present from the introduction of the hardened usercopy feature.

As such it's useful to build one when building the kernel, but to do so currently requires the user to manually specify a uImage target on the make command line. Make uImage.gz the pistachio platform's default build target, so that the default is to build a kernel image that we can actually boot on a board such as the MIPS Creator Ci40. Marked for stable backport as far as v4.1 where pistachio support was introduced. This is primarily useful for CI systems such as kernelci.org which will benefit from us building a suitable image which can then be booted as part of automated testing, extending our test coverage to the affected stable branches.

This is referred as EQ provisioning and it is done under the hood when : 1. a CPU is hot-plugged in the VM 2. the "set-xive" is called at VM startup 3. sources are restored at VM restore The kvm->lock mutex is used to protect the different XIVE structures being modified but in some contexts, kvm->lock is taken under the vcpu->mutex which is not permitted by the KVM locking rules. Introduce a new mutex 'lock' for the KVM devices for them to synchronize accesses to the XIVE device structures.

They are made available to guests through a mapping of the XIVE KVM device. When a device is passed-through, the passthru_irq helpers, kvmppc_xive_set_mapped() and kvmppc_xive_clr_mapped(), clear the ESB pages of the guest IRQ number being mapped and let the VM fault handler repopulate with the correct page. The ESB pages are mapped at offset 4 (KVM_XIVE_ESB_PAGE_OFFSET) in the KVM device mapping. Unfortunately, this offset was not taken into account when clearing the pages. This lead to issues with the passthrough devices for which the interrupts were not functional under some guest configuration (tg3 and single CPU) or in any configuration (e1000e adapter).

Wysocki" Date: Mon, 27 May 2019 12:56:07 +0200 Subject: x86: intel_epb: Do not build when CONFIG_PM is unset Commit 9ed0985332a6 ("x86: intel_epb: Take CONFIG_PM into account") prevented the majority of the Performance and Energy Bias Hint (EPB) handling code from being built when CONFIG_PM is unset to fix a regression introduced by commit b9c273babce7 ("PM / arch: x86: MSR_IA32_ENERGY_PERF_BIAS sysfs interface"). In hindsight, however, it would be better to skip all of the EPB handling code for CONFIG_PM unset as there really is no reason for it to be there in that case. Namely, if the EPB is not touched by the kernel at all with CONFIG_PM unset, there is no need to worry about modifying the EPB inadvertently on CPU online and since the system will not suspend or hibernate then, there is no need to worry about possible modifications of the EPB by the platform firmware during system-wide PM transitions. For this reason, revert the changes made by commit 9ed0985332a6 and only allow intel_epb.o to be built when CONFIG_PM is set. Note that this changes the behavior of the kernels built with CONFIG_PM unset as they will not modify the EPB on boot if it is zero initially any more, so it is not a fix strictly speaking, but users building their kernels with CONFIG_PM unset really should not expect them to take energy efficiency into account. Moreover, if CONFIG_PM is unset for performance reasons, leaving EPB as set initially by the platform firmware will actually be consistent with the user's expectations. Signed-off-by: Rafael J.

We need to disable this DT node by default. Setups that want to access the flash can modify this entry to enable the flash again but also ensuring to disable CPU idle states and CPU hotplug. The platform firmware assumes the flash is always in read mode while Linux kernel driver leaves NOR flash in "read id" mode after initialization. If it gets used actively, it can be in some other state. So far we had not seen this issue as the NOR flash drivers in kernel were not enabled by default. However it was enable in multi_v7 config by Commit 5f068190cc10 ("ARM: multi_v7_defconfig: Enable support for CFI NOR FLASH") So, let's mark the NOR flash disabled so that the platform can boot again.

However, if the IEX flag has been raised before this floating point emulation, this cleanup may be incorrect. To avoid the IEX flags in $fpcsr be raised in each denormalized output handling, the IEX trap shall be always enabled.

These existing FPU emulations are not sufficient when IEx Trap is enabled because some floating point instructions only issue inexact exception. This patch adds the emulations of such floating point instructions.

As the psci_smp_available() helper always returns false if CONFIG_SMP is disabled, it can't be used safely as an indicator of PSCI usage. For that reason, we check for the mandatory PSCI operation to be available. Please note, an extra check to prevent secure_cntvoff_init() from being called for secondary CPUs in headsmp-apmu.S is not needed, as SMP code for APMU based system is not executed if PSCI is in use.

The current BPF JIT on RISC-V emits incorrect instructions that perform sign extension only (e.g., addw, subw) on 32-bit add, sub, lsh, rsh, arsh, and neg. This behavior diverges from the interpreter and JITs for other architectures. This patch fixes the bugs by performing zero extension on the destination register of 32-bit ALU operations.

The SPDX solves this issue, assuming people can correctly spell "SPDX-License-Identifier" although this assumption is broken in some places. Since scripts/spdxcheck.py parses only lines that exactly matches to the correct tag, it cannot (should not) detect this kind of error. If the correct tag is missing, scripts/checkpatch.pl warns like this: WARNING: Missing or malformed SPDX-License-Identifier tag in line * So, people should notice it before the patch submission, but in reality broken tags sometimes slip in. The checkpatch warning is not useful for checking the committed files globally since large number of files still have no SPDX tag. Also, I am not sure about the legal effect when the SPDX tag is broken. Anyway, these typos are absolutely worth fixing.

This has the effect of incrementing the reference count of the PCI device, as explained in drivers/pci/search.c: * Given a PCI domain, bus, and slot/function number, the desired PCI * device is located in the list of PCI devices. If the device is * found, its reference count is increased and this function returns a * pointer to its data structure. The caller must decrement the * reference count by calling pci_dev_put(). If no device is found, * %NULL is returned. Nothing was done to call pci_dev_put() and the reference count of GPU and NPU PCI devices rockets up. A natural way to fix this would be to teach the callers about the change, so that they call pci_dev_put() when done with the pointer. This turns out to be quite intrusive, as it affects many paths in npu-dma.c, pci-ioda.c and vfio_pci_nvlink2.c. Also, the issue appeared in 4.16 and some affected code got moved around since then: it would be problematic to backport the fix to stable releases. All that code never cared for reference counting anyway. Call pci_dev_put() from get_pci_dev() to revert to the previous behavior.

NIP xics_smp_probe+0x38/0x98 LR xics_smp_probe+0x2c/0x98 Call Trace: xics_smp_probe+0x2c/0x98 (unreliable) pSeries_smp_probe+0x40/0xa0 smp_prepare_cpus+0x62c/0x6ec kernel_init_freeable+0x148/0x448 kernel_init+0x2c/0x148 ret_from_kernel_thread+0x5c/0x68 Look for xive=off during prom_init and don't ask for XIVE in this case. One exception though: if the host only supports XIVE, we still want to boot so we ignore xive=off. Similarly, have the spapr XIVE init code to looking at the interrupt mode negotiated during CAS, and ignore xive=off if the hypervisor only supports XIVE.

Mon Sep 17 00:00:00 2001 From: James Clarke Date: Wed, 29 May 2019 22:31:31 +0100 Subject: sparc64: Fix regression in non-hypervisor TLB flush xcall Previously, %g2 would end up with the value PAGE_SIZE, but after the commit mentioned below it ends up with the value 1 due to being reused for a different purpose. We need it to be PAGE_SIZE as we use it to step through pages in our demap loop, otherwise we set different flags in the low 12 bits of the address written to, thereby doing things other than a nucleus page flush.

Consequently, when calculating the next event period, the new period will only be considered after the previous one has overflowed. This patch changes the calculation of the remaining event ticks so that they are offset if the period has changed.

v1.2.3 From 3bd3706251ee8ab67e69d9340ac2abdca217e733 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 23 Apr 2019 16:26:36 +0200 Subject: sched/core: Provide a pointer to the valid CPU mask In commit: 4b53a3412d66 ("sched/core: Remove the tsk_nr_cpus_allowed() wrapper") the tsk_nr_cpus_allowed() wrapper was removed. There was not much difference in !RT but in RT we used this to implement migrate_disable(). Within a migrate_disable() section the CPU mask is restricted to single CPU while the "normal" CPU mask remains untouched. As an alternative implementation Ingo suggested to use: struct task_struct { const cpumask_t *cpus_ptr; cpumask_t cpus_mask; }; with t->cpus_ptr = &t->cpus_mask; In -RT we then can switch the cpus_ptr to: t->cpus_ptr = &cpumask_of(task_cpu(p)); in a migration disabled region. The rules are simple: - Code that 'uses' ->cpus_allowed would use the pointer. - Code that 'modifies' ->cpus_allowed would use the direct mask.

That means that whenever 'nosmt' is supplied on the kernel command-line, all the HT siblings are as a result sitting in mwait or cpudile after going through the online-offline cycle at least once. This causes a serious issue though when a kernel, which saw 'nosmt' on its commandline, is going to perform resume from hibernation: if the resume from the hibernated image is successful, cr3 is flipped in order to point to the address space of the kernel that is being resumed, which in turn means that all the HT siblings are all of a sudden mwaiting on address which is no longer valid. That results in triple fault shortly after cr3 is switched, and machine reboots. Fix this by always waking up all the SMT siblings before initiating the 'restore from hibernation' process; this guarantees that all the HT siblings will be properly carried over to the resumed kernel waiting in resume_play_dead(), and acted upon accordingly afterwards, based on the target kernel configuration. Symmetricaly, the resumed kernel has to push the SMT siblings to mwait again in case it has SMT disabled; this means it has to online all the siblings when resuming (so that they come out of hlt) and offline them again to let them reach mwait.

It may return long (e.g. powerpc), long long (e.g. arm), or s64 (e.g. x86_64). This is somewhat painful, and mandates the use of explicit casts in some cases (e.g. when printing the return value). To ameliorate matters, subsequent patches will make the atomic64 API consistently use s64. As a preparatory step, this patch updates the s390 pci debug code to treat the return value of atomic64_read() as s64, using an explicit cast. This cast will be removed once the s64 conversion is complete.

As atomic64_read() depends on the generic defintion of atomic64_t, this still returns long. This will be converted in a subsequent patch. Note that in arch_atomic64_dec_if_positive(), the x0 variable is left as long, as this variable is also used to hold the pointer to the atomic64_t.

Thus, if called with a 64-bit offset, the value will be unexpectedly truncated to 32 bits. Fix this by taking the offset as a long rather than an int.

So far, when the temperature reaches 100°C in the thermal IP of the AP806 (close enough from the 2/4 cores) an overheat interrupt is raised. The thermal core then shutdowns the system to avoid damaging the hardware. Adding CPUfreq as a cooling device could help avoiding such very critical situation. For that, we enable thermal throttling by defining, for each CPU, two trip points with the corresponding cooling 'intensity'. CPU0 and CPU1 are in the same cluster and are driven by the same clock. Same applies for CPU2 and CPU3, if available. So changing the frequency of one will also change the frequency of the other one, hence the use of two cooling devices per core. The heat map is as follow: - Below 85°C: the cluster runs at the highest frequency (e.g: 1200MHz). - Between 85°C and 95°C: there are two trip points at half (e.g: 600MHz) and a third (e.g: 400MHz) of the highest frequency. - Above 95°C the cluster runs at a quarter of the highest frequency (e.g: 300MHz). - At 100°C the platform is shutdown.

There is no way to tell which is placed on the board since no revision bump takes place. This creates two issues. The first, cosmetic. Since the NOR chip may differ, there's message on boot stating that kernel expected w25q32dw and found different one. To correct this, remove optional device-specific compatible string. Being here lets replace bogus "spi-flash" compatible string with proper one. The second is linked to partitions layout, it changed after commit: 81e7251252 ("arm64: mvebu: config: move env to the end of the 4MB boot device") in Marvells downstream U-Boot fork [1], shifting environment location to the end of boot device. Since the new boards will have U-Boot with this change, it'll lead to improper results writing or reading from these partitions. We can't tell if users will update bootloader to recent version provided on manufacturer website, so lets drop partitons layout. 1. https://github.com/MarvellEmbeddedProcessors/u-boot-marvell.git Signed-off-by: Tomasz Maciej Nowak Signed-off-by: Gregory CLEMENT --- .../arm64/boot/dts/marvell/armada-3720-espressobin.dts | 18 +----------------- 1 file changed, 1 insertion(+), 17 deletions(-) (limited to 'arch') diff --git a/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts b/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts index 6be019e1888e..fbcf03f86c96 100644 --- a/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts +++ b/arch/arm64/boot/dts/marvell/armada-3720-espressobin.dts @@ -95,25 +95,9 @@ flash@0 { reg = <0>; - compatible = "winbond,w25q32dw", "jedec,spi-flash"; + compatible = "jedec,spi-nor"; spi-max-frequency = <104000000>; m25p,fast-read; - - partitions { - compatible = "fixed-partitions"; - #address-cells = <1>; - #size-cells = <1>; - - partition@0 { - label = "uboot"; - reg = <0 0x180000>; - }; - - partition@180000 { - label = "ubootenv"; - reg = <0x180000 0x10000>; - }; - }; }; }; -- cgit v1.2.3 From 318759b4737c3b3789e2fd64d539f437d52386f5 Mon Sep 17 00:00:00 2001 From: "Eric W.

A following patch will introduce a mechanism to acquire owernship of the FPSIMD/SVE context for performing context management operations. Rather than having to export the new helpers to get/put the context, we can just introduce a new function to combine fpsimd_save() and fpsimd_flush_cpu_state(). This has also the advantage to remove any external call of fpsimd_save() and fpsimd_flush_cpu_state(), so they can be turned static. Lastly, the new function can also be used in the PM notifier.

This is for instance the case for crypto code. Any use of FPSIMD/SVE in the kernel are clearly marked by using the function kernel_neon_{begin, end}. Furthermore, this can only be used when may_use_simd() returns true. The current implementation of may_use_simd() allows softirq to use FPSIMD/SVE unless it is currently in use (i.e kernel_neon_busy is true). When in use, softirqs usually fall back to a software method. At the moment, as a softirq may use FPSIMD/SVE, softirqs are disabled when touching the FPSIMD/SVE context. This has the drawback to disable all softirqs even if they are not using FPSIMD/SVE. Since a softirq is supposed to check may_use_simd() anyway before attempting to use FPSIMD/SVE, there is limited reason to keep softirq disabled when touching the FPSIMD/SVE context. Instead, we can simply disable preemption and mark the FPSIMD/SVE context as in use by setting CPU's fpsimd_context_busy flag. Two new helpers {get, put}_cpu_fpsimd_context are introduced to mark the area using FPSIMD/SVE context and they are used to replace local_bh_{disable, enable}. The functions kernel_neon_{begin, end} are also re-implemented to use the new helpers. Additionally, double-underscored versions of the helpers are provided to called when preemption is already disabled. These are only relevant on paths where irqs are disabled anyway, so they are not needed for correctness in the current code. Let's use them anyway though: this marks critical sections clearly and will help to avoid mistakes during future maintenance. The change has been benchmarked on Linux 5.1-rc4 with defconfig.

Therefore a raw_spin_lock() is required here. Given this is already done under stop_machine() and the work done under the lock is quite small, the latency should not increase too much.

In case of failure it just bails out without holding mmap_sem but when it succeeds it does so while holding mmap_sem. Fix this inconsistency by just dropping mmap_sem in success path as well. __do_kernel_fault() calls die_kernel_fault() which then calls show_pte(). show_pte() in this path might become bit more unreliable without holding mmap_sem. But there are already instances [1] in do_page_fault() where die_kernel_fault() gets called without holding mmap_sem. show_pte() can be made more robust independently but in a later patch.

Exactly how many bits are reduced is configured by BIOS. To honor such HW behavior, the repurposed bits are reduced from cpuinfo_x86->x86_phys_bits when MKTME is detected in CPU detection. Similarly, AMD SME/SEV also reduces physical address bits for memory encryption, and cpuinfo->x86_phys_bits is reduced too when SME/SEV is detected, so for both MKTME and SME/SEV, boot_cpu_data.x86_phys_bits doesn't hold physical address bits reported by CPUID anymore. Currently KVM treats bits from boot_cpu_data.x86_phys_bits to 51 as reserved bits, but it's not true anymore for MKTME, since MKTME treats those reduced bits as 'keyID', but not reserved bits. Therefore boot_cpu_data.x86_phys_bits cannot be used to calculate reserved bits anymore, although we can still use it for AMD SME/SEV since SME/SEV treats the reduced bits differently -- they are treated as reserved bits, the same as other reserved bits in page table entity [1]. Fix by introducing a new 'shadow_phys_bits' variable in KVM x86 MMU code to store the effective physical bits w/o reserved bits -- for MKTME, it equals to physical address reported by CPUID, and for SME/SEV, it is boot_cpu_data.x86_phys_bits. Note that for the physical address bits reported to guest should remain unchanged -- KVM should report physical address reported by CPUID to guest, but not boot_cpu_data.x86_phys_bits. Because for Intel MKTME, there's no harm if guest sets up 'keyID' bits in guest page table (since MKTME only works at physical address level), and KVM doesn't even expose MKTME to guest. Arguably, for AMD SME/SEV, guest is aware of SEV thus it should adjust boot_cpu_data.x86_phys_bits when it detects SEV, therefore KVM should still reports physcial address reported by CPUID to guest.

However, it just hidden the time between apic_timer_fn/handle_preemption_timer -> wait_lapic_expire, instead of the real position of vmentry which is mentioned in the orignial commit d0659d946be0 ("KVM: x86: add option to advance tscdeadline hrtimer expiration"). There is 700+ cpu cycles between the end of wait_lapic_expire and before world switch on my haswell desktop. This patch tries to narrow the last gap(wait_lapic_expire -> world switch), it takes the real overhead time between apic_timer_fn/handle_preemption_timer and before world switch into consideration when adaptively tuning timer advancement. The patch can reduce 40% latency (~1600+ cycles to ~1000+ cycles on a haswell desktop) for kvm-unit-tests/tscdeadline_latency when testing busy waits.

While the x86 specific issue could be resolved solely by changing kvm_x86_ops, make the change for all architectures as returning a value directly is prettier and technically more robust, e.g. s390 doesn't set the out param, which could lead to subtle breakage in the (highly unlikely) scenario where the out-param was not pre-initialized by the caller.

A few notes: - While there is most certainly duplication between all the veyron boards, it still feels like it is sane to just have each board have a full list of its pin names. The format of "gpio-line-names" does not lend itself to one-off overriding and besides it seems sane to more fully match schematic names. Also note that the extra duplication here is only in source code and is unlikely to ever change (since these boards are shipped). Duplication in the .dtb files is unavoidable. - veyron-jaq and veyron-mighty are very closely related and so I have shared a single list for them both with comments on how they are different. This is just a typo fix on one of the boards, a possible missing signal on one of the boards (or perhaps I was never given the most recent schematics?) and dealing with the fact that one of the two boards has full sized SD.

Since these registers are found at a consecutive range of addresses we access them using an index, via the (read|write)_gic_v[lo]_map accessor functions. We currently use values from enum mips_gic_local_interrupt as those indices. Unfortunately whilst enum mips_gic_local_interrupt provides the correct offsets for bits in the pending & mask registers, the ordering of the map registers is subtly different... Compared with the ordering of pending & mask bits, the map registers move the FDC from the end of the list to index 3 after the timer interrupt. As a result the performance counter & software interrupts are therefore at indices 4-6 rather than indices 3-5. Notably this causes problems with performance counter interrupts being incorrectly mapped on some systems, and presumably will also cause problems for FDC interrupts.

In order to check compatibility of secondary cpus with the hwcaps established at boot, the cpufeatures code uses __read_sysreg_by_encoding() to read this ID register based on the sys_reg field of the arm64_elf_hwcaps[] table. This leads to a kernel splat if an hwcap uses an ID register that __read_sysreg_by_encoding() doesn't explicitly handle, as now happens when exercising cpu hotplug on an SVE2-capable platform.

However, user space could still switch to access register mode (trans_exc_code == 1), and exceptions in that mode would not be correctly assigned. Fix this by adding a check for trans_exc_code == 1 to get_fault_type(), and remove the wrong comment line before that function.

Though handling of PTRACE_SYSEMU can be made architecture independent, it's hard to make these definations generic. To add to this existing mess few architectures like arm, c6x and sh use 31 for PTRACE_GETFDPIC (get the ELF fdpic loadmap address). It's not possible to move the definations to generic headers. So we unfortunately have to duplicate the same defination to ARM64 if we need to support PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.

This is because the property should only be used when a board does not provide a proper AVB_LINK signal. However, the Ebisu board does provide this signal. As per 87c059e9c39d ("arm64: dts: renesas: salvator-x: Remove renesas, no-ether-link property") this fixes a bug: Steps to reproduce: - start AVB TX stream (Using aplay via MSE), - disconnect+reconnect the eth cable, - after a reconnection the eth connection goes iteratively up/down without user interaction, - this may heal after some seconds or even stay for minutes. As the documentation specifies, the "renesas,no-ether-link" option should be used when a board does not provide a proper AVB_LINK signal. There is no need for this option enabled on RCAR H3/M3 Salvator-X/XS and ULCB starter kits since the AVB_LINK is correctly handled by HW. Choosing to keep or remove the "renesas,no-ether-link" option will have impact on the code flow in the following ways: - keeping this option enabled may lead to unexpected behavior since the RX & TX are enabled/disabled directly from adjust_link function without any HW interrogation, - removing this option, the RX & TX will only be enabled/disabled after HW interrogation. The HW check is made through the LMON pin in PSR register which specifies AVB_LINK signal value (0 - at low level; 1 - at high level). In conclusion, the present change is also a safety improvement because it removes the "renesas,no-ether-link" option leading to a proper way of detecting the link state based on HW interrogation and not on software heuristic.

Create passive trip points and bind them to CPUFreq cooling device that supports power extension. In R-Car Gen3, IPA is supported for only one channel (on H3/M3/M3N SoCs, it is channel THS3). Reason: Currently, IPA controls base on only CPU temperature. And only one thermal channel is assembled closest CPU cores is selected as target of IPA. If other channels are used, IPA controlling is not properly. The A5 cooling device supports 5 cooling states which can be categorised as follows: 0 & 1) boost (clocking up) 2) default 3 & 4) cooling (clocking down) Currently the thermal framework assumes that the default is the minimum, or in other words there is no provision for handling boost states. So this patch only describes the upper 3 states, default and cooling. A single cooling device is described for all A57 CPUs and a separate cooling device is described for all A53 CPUs. This reflects that physically there is only one cooling device present for each type of CPU. This patch improves on an earlier version by: * Omitting cooling-max-level and cooling-min-level properties which are no longer present in mainline as of v4.17 * Removing an unused trip-point0 node sub-property from the trips property. * Using cooling-device indexes such that maximum refers to maximum cooling rather than the inverse. * Defers adding dynamic-power-coefficient properties to a separate patch as these are properties of the CPU.

However, there is one API that uses aliased kernel address ranges: > The final category of APIs is for I/O to deliberately aliased address > ranges inside the kernel. Such aliases are set up by use of the > vmap/vmalloc API. Since kernel I/O goes via physical pages, the I/O > subsystem assumes that the user mapping and kernel offset mapping are > the only aliases. This isn't true for vmap aliases, so anything in > the kernel trying to do I/O to vmap areas must manually manage > coherency. It must do this by flushing the vmap range before doing > I/O and invalidating it after the I/O returns. For this reason, we should use the hardware lpa instruction to load the physical address of kernel virtual addresses in the driver code. I believe we only use the vmap/vmalloc API with old PA 1.x processors which don't have a sba, so we don't hit this problem. Tested on c3750, c8000 and rp3440.

We have no documentation for PCX-W+ (PA8600) and PCX-W2 (PA8700) CPUs, but Carlo Pisani reported that his C3600 machine (PA8600, PCX-W+) fails when the fdc instructions were removed. His firmware didn't set the NIOP bit, so one may assume it's a firmware bug since other C3750 machines had the bit set. Even if documentation (as mentioned above) states that PCX-W (PA8500, e.g. J5000) does not need fdc flushes, Sven could show that an Adaptec 29320A PCI-X SCSI controller reliably failed on a dd command during the first five minutes in his J5000 when fdc flushes were missing. Going forward, we will now NOT replace the fdc and sync assembler instructions by NOPS if: a) the NP iopdir_fdc bit was set by firmware, or b) we find a CPU up to and including a PCX-W+ (PA8600). This fixes the HPMC crashes on a C240 and C36XX machines. For other machines we rely on the firmware to set the bit when needed. In case one finds HPMC issues, people could try to boot their machines with the "no-alternatives" kernel option to turn off any alternative patching.

The kernel is a standalone binary, and of course nobody would be so stupid as to expose structs containing bitfields as function arguments in ABI. (Passing a pointer to such a struct, however inadvisable, should be unaffected by this change. perf and various drivers rely on that.) So these warnings do more harm than good: turn them off. We may miss warnings about future ABI drift, but that's too bad. Future ABI breaks of this class will have to be debugged and fixed the traditional way unless the compiler evolves finer-grained diagnostics.

This works in general and uncovered a bug as reported by Mike Rapoport¹. It has been pointed out that this function may be fragile and a simple pre-fault as in fault_in_pages_writeable() would be a better solution. Better as in taste and simplicity: that write (as performed by the alternative function) performs exactly the same faulting of memory as before. This was suggested by Hugh Dickins and Andrew Morton. Use fault_in_pages_writeable() for pre-faulting user's stack.

However, the recent addition of RSDP parsing in the decompression stage and especially: 33f0df8d843d ("x86/boot: Search for RSDP in the EFI tables") which tries to access EFI system tables and to dig out the RDSP address from there, becomes a problem because in certain configurations, they might not be mapped in the kexec'ed kernel's address space. What is more, this problem doesn't appear on all systems because the kexec kernel uses gigabyte pages to build the identity mapping. And the EFI system tables and ACPI tables can, depending on the system configuration, end up being mapped as part of all physical memory, if they share the same 1 GB area with the physical memory. Therefore, make sure they're always mapped.

Therefore, allthough __mapin_ram_chunk() was already mapping kernel text with PAGE_KERNEL_TEXT and the rest with PAGE_KERNEL, the entire memory was executable. Part of the memory (first 512kbytes) was mapped with BATs instead of page table, but it was also entirely mapped as executable. In commit 385e89d5b20f ("powerpc/mm: add exec protection on powerpc 603"), we started adding exec protection to some 6xx, namely the 603, for pages mapped via pagetables. Then, in commit 63b2bc619565 ("powerpc/mm/32s: Use BATs for STRICT_KERNEL_RWX"), the exec protection was extended to BAT mapped memory, so that really only the kernel text could be executed. The problem here is that kexec is based on copying some code into upper part of memory then executing it from there in order to install a fresh new kernel at its definitive location. However, the code is position independant and first part of it is just there to deactivate the MMU and jump to the second part. So it is possible to run this first part inplace instead of running the copy. Once the MMU is off, there is no protection anymore and the second part of the code will just run as before.

The pte_present() change now returns true for PTEs which are !_PAGE_PRESENT and _PAGE_INVALID, which is the combination used by pmdp_invalidate() to synchronize access from lock-free lookups. pte_access_permitted() is used by pmd_access_permitted(), so allowing GUP lock free access to proceed with such PTEs breaks this synchronisation. This bug has been observed on a host using the hash page table MMU, with random crashes and corruption in guests, usually together with bad PMD messages in the host. Fix this by adding an explicit check in pmd_access_permitted(), and documenting the condition explicitly. The pte_write() change should be okay, and would prevent GUP from falling back to the slow path when encountering savedwrite PTEs, which matches what x86 (that does not implement savedwrite) does.

In addition the kernel currently doesn't even compile with CONFIG_SMP=n for s390. Most likely it wouldn't even work, even if we fix the compile error, since nobody tests it, since there is no use case that I can think of. Therefore simply enforce CONFIG_SMP and get rid of some more or less unused code.

By change, it used to work because BOOTX buffer is mapped 1:1 at address 0x81000000 by the bootloader, and btext_setup_display() sets virt addr same as phys addr. But since commit 215b823707ce ("powerpc/32s: set up an early static hash table for KASAN."), a temporary page table overrides the bootloader mapping. This 0x81000000 is also problematic with the newly implemented Kernel Userspace Access Protection (KUAP) because it is within user address space. This patch fixes those issues by properly setting disp_BAT through a call to btext_prepare_BAT(), allowing setup_disp_bat() to properly setup BAT3 for early bootx screen buffer access.

However, 1 TB is not enough for vmemmap in 5-level paging mode. Assuming the size of struct page is 64 Bytes, to support 4 PB system RAM in 5-level, 64 TB of vmemmap area is needed: 4 * 1000^5 PB / 4096 bytes page size * 64 bytes per page struct / 1000^4 TB = 62.5 TB. This hardcoding may cause vmemmap to corrupt the following cpu_entry_area section, if KASLR puts vmemmap very close to it and the actual vmemmap size is bigger than 1 TB. So calculate the actual size of the vmemmap region needed and then align it up to 1 TB boundary. In 4-level paging mode it is always 1 TB. In 5-level it's adjusted on demand. The current code reserves 0.5 PB for vmemmap on 5-level. With this change, the space can be saved and thus used to increase entropy for the randomization.

The workaround in the gpiolib.c can be removed and cases (such as SPI CS) where we need at times to request a GPIO with line inversion semantics directly on a chip for workarounds, can be fully supported with this call. Fix up some users of the API that weren't really using the last flag to set up the line as input or output properly but instead just calling direction setting explicitly after requesting the line.

The required mcount call sequences can get pretty long, so instead of patching the whole call sequence out of the functions, we are using -fpatchable-function-entry from gcc. This puts a configurable amount of NOPS before/at the start of the function. Taking do_sys_open() as example, which would look like this when the call is patched out: 1036b248: 08 00 02 40 nop 1036b24c: 08 00 02 40 nop 1036b250: 08 00 02 40 nop 1036b254: 08 00 02 40 nop 1036b258 : 1036b258: 08 00 02 40 nop 1036b25c: 08 03 02 41 copy r3,r1 1036b260: 6b c2 3f d9 stw rp,-14(sp) 1036b264: 08 1e 02 43 copy sp,r3 1036b268: 6f c1 01 00 stw,ma r1,80(sp) When ftrace gets enabled for this function the kernel will patch these NOPs to: 1036b248: 10 19 57 20
1036b24c: 6f c1 00 80 stw,ma r1,40(sp) 1036b250: 48 21 3f d1 ldw -18(r1),r1 1036b254: e8 20 c0 02 bv,n r0(r1) 1036b258 : 1036b258: e8 3f 1f df b,l,n .-c,r1 1036b25c: 08 03 02 41 copy r3,r1 1036b260: 6b c2 3f d9 stw rp,-14(sp) 1036b264: 08 1e 02 43 copy sp,r3 1036b268: 6f c1 01 00 stw,ma r1,80(sp) So the first NOP in do_sys_open() will be patched to jump backwards into some minimal trampoline code which pushes a stackframe, saves r1 which holds the return address, loads the address of the real ftrace function, and branches to that location. For 64 Bit things are getting a bit more complicated (and longer) because we must make sure that the address of ftrace location is 8 byte aligned, and the offset passed to ldd for fetching the address is 8 byte aligned as well. Note that gcc has a bug which misplaces the function label, and needs a patch to make dynamic ftrace work. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90751 for details.

7f192e3cd316ba58c88dfa26796cf77789dd9872 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Sat, 25 May 2019 11:36:41 +0200 Subject: fork: add clone3 This adds the clone3 system call. As mentioned several times already (cf. [7], [8]) here's the promised patchset for clone3(). We recently merged the CLONE_PIDFD patchset (cf. [1]). It took the last free flag from clone(). Independent of the CLONE_PIDFD patchset a time namespace has been discussed at Linux Plumber Conference last year and has been sent out and reviewed (cf. [5]). It is expected that it will go upstream in the not too distant future. However, it relies on the addition of the CLONE_NEWTIME flag to clone(). The only other good candidate - CLONE_DETACHED - is currently not recyclable as we have identified at least two large or widely used codebases that currently pass this flag (cf. [2], [3], and [4]). Given that CLONE_PIDFD grabbed the last clone() flag the time namespace is effectively blocked. clone3() has the advantage that it will unblock this patchset again. In general, clone3() is extensible and allows for the implementation of new features. The idea is to keep clone3() very simple and close to the original clone(), specifically, to keep on supporting old clone()-based workloads. We know there have been various creative proposals how a new process creation syscall or even api is supposed to look like. Some people even going so far as to argue that the traditional fork()+exec() split should be abandoned in favor of an in-kernel version of spawn(). Independent of whether or not we personally think spawn() is a good idea this patchset has and does not want to have anything to do with this. One stance we take is that there's no real good alternative to clone()+exec() and we need and want to support this model going forward; independent of spawn(). The following requirements guided clone3(): - bump the number of available flags - move arguments that are currently passed as separate arguments in clone() into a dedicated struct clone_args - choose a struct layout that is easy to handle on 32 and on 64 bit - choose a struct layout that is extensible - give new flags that currently need to abuse another flag's dedicated return argument in clone() their own dedicated return argument (e.g. CLONE_PIDFD) - use a separate kernel internal struct kernel_clone_args that is properly typed according to current kernel conventions in fork.c and is different from the uapi struct clone_args - port _do_fork() to use kernel_clone_args so that all process creation syscalls such as fork(), vfork(), clone(), and clone3() behave identical (Arnd suggested, that we can probably also port do_fork() itself in a separate patchset.) - ease of transition for userspace from clone() to clone3() This very much means that we do *not* remove functionality that userspace currently relies on as the latter is a good way of creating a syscall that won't be adopted. - do not try to be clever or complex: keep clone3() as dumb as possible In accordance with Linus suggestions (cf. [11]), clone3() has the following signature: /* uapi */ struct clone_args { __aligned_u64 flags; __aligned_u64 pidfd; __aligned_u64 child_tid; __aligned_u64 parent_tid; __aligned_u64 exit_signal; __aligned_u64 stack; __aligned_u64 stack_size; __aligned_u64 tls; }; /* kernel internal */ struct kernel_clone_args { u64 flags; int __user *pidfd; int __user *child_tid; int __user *parent_tid; int exit_signal; unsigned long stack; unsigned long stack_size; unsigned long tls; }; long sys_clone3(struct clone_args __user *uargs, size_t size) clone3() cleanly supports all of the supported flags from clone() and thus all legacy workloads. The advantage of sticking close to the old clone() is the low cost for userspace to switch to this new api. Quite a lot of userspace apis (e.g. pthreads) are based on the clone() syscall. With the new clone3() syscall supporting all of the old workloads and opening up the ability to add new features should make switching to it for userspace more appealing. In essence, glibc can just write a simple wrapper to switch from clone() to clone3(). There has been some interest in this patchset already. We have received a patch from the CRIU corner for clone3() that would set the PID/TID of a restored process without /proc/sys/kernel/ns_last_pid to eliminate a race. /* User visible differences to legacy clone() */ - CLONE_DETACHED will cause EINVAL with clone3() - CSIGNAL is deprecated It is superseeded by a dedicated "exit_signal" argument in struct clone_args freeing up space for additional flags. This is based on a suggestion from Andrei and Linus (cf. [9] and [10]) /* References */ [1]: b3e5838252665ee4cfa76b82bdf1198dca81e5be [2]: https://dxr.mozilla.org/mozilla-central/source/security/sandbox/linux/SandboxFilter.cpp#343 [3]: https://git.musl-libc.org/cgit/musl/tree/src/thread/pthread_create.c#n233 [4]: https://sources.debian.org/src/blcr/0.8.5-2.3/cr_module/cr_dump_self.c/?hl=740#L740 [5]: https://lore.kernel.org/lkml/20190425161416.26600-1-dima@arista.com/ [6]: https://lore.kernel.org/lkml/20190425161416.26600-2-dima@arista.com/ [7]: https://lore.kernel.org/lkml/CAHrFyr5HxpGXA2YrKza-oB-GGwJCqwPfyhD-Y5wbktWZdt0sGQ@mail.gmail.com/ [8]: https://lore.kernel.org/lkml/20190524102756.qjsjxukuq2f4t6bo@brauner.io/ [9]: https://lore.kernel.org/lkml/20190529222414.GA6492@gmail.com/ [10]: https://lore.kernel.org/lkml/CAHk-=whQP-Ykxi=zSYaV9iXsHsENa+2fdj-zYKwyeyed63Lsfw@mail.gmail.com/ [11]: https://lore.kernel.org/lkml/CAHk-=wieuV4hGwznPsX-8E0G2FKhx3NjZ9X3dTKh5zKd+iqOBw@mail.gmail.com/ Suggested-by: Linus Torvalds Signed-off-by: Christian Brauner Acked-by: Arnd Bergmann Acked-by: Serge Hallyn Cc: Kees Cook Cc: Pavel Emelyanov Cc: Jann Horn Cc: David Howells Cc: Andrew Morton Cc: Oleg Nesterov Cc: Adrian Reber Cc: Linus Torvalds Cc: Andrei Vagin Cc: Al Viro Cc: Florian Weimer Cc: linux-api@vger.kernel.org --- arch/x86/ia32/sys_ia32.c | 12 ++- include/linux/sched/task.h | 17 +++- include/linux/syscalls.h | 4 + include/uapi/linux/sched.h | 16 ++++ kernel/fork.c | 201 ++++++++++++++++++++++++++++++++++----------- 5 files changed, 199 insertions(+), 51 deletions(-) (limited to 'arch') diff --git a/arch/x86/ia32/sys_ia32.c b/arch/x86/ia32/sys_ia32.c index a43212036257..64a6c952091e 100644 --- a/arch/x86/ia32/sys_ia32.c +++ b/arch/x86/ia32/sys_ia32.c @@ -237,6 +237,14 @@ COMPAT_SYSCALL_DEFINE5(x86_clone, unsigned long, clone_flags, unsigned long, newsp, int __user *, parent_tidptr, unsigned long, tls_val, int __user *, child_tidptr) { - return _do_fork(clone_flags, newsp, 0, parent_tidptr, child_tidptr, - tls_val); + struct kernel_clone_args args = { + .flags = (clone_flags & ~CSIGNAL), + .child_tid = child_tidptr, + .parent_tid = parent_tidptr, + .exit_signal = (clone_flags & CSIGNAL), + .stack = newsp, + .tls = tls_val, + }; + + return _do_fork(&args); } diff --git a/include/linux/sched/task.h b/include/linux/sched/task.h index f1227f2c38a4..109a0df5af39 100644 --- a/include/linux/sched/task.h +++ b/include/linux/sched/task.h @@ -8,11 +8,26 @@ */ #include +#include struct task_struct; struct rusage; union thread_union; +/* All the bits taken by the old clone syscall. */ +#define CLONE_LEGACY_FLAGS 0xffffffffULL + +struct kernel_clone_args { + u64 flags; + int __user *pidfd; + int __user *child_tid; + int __user *parent_tid; + int exit_signal; + unsigned long stack; + unsigned long stack_size; + unsigned long tls; +}; + /* * This serializes "schedule()" and also protects * the run-queue from deletions/modifications (but @@ -73,7 +88,7 @@ extern void do_group_exit(int); extern void exit_files(struct task_struct *); extern void exit_itimers(struct signal_struct *); -extern long _do_fork(unsigned long, unsigned long, unsigned long, int __user *, int __user *, unsigned long); +extern long _do_fork(struct kernel_clone_args *kargs); extern long do_fork(unsigned long, unsigned long, unsigned long, int __user *, int __user *); struct task_struct *fork_idle(int); struct mm_struct *copy_init_mm(void); diff --git a/include/linux/syscalls.h b/include/linux/syscalls.h index e2870fe1be5b..60a81f374ca3 100644 --- a/include/linux/syscalls.h +++ b/include/linux/syscalls.h @@ -70,6 +70,7 @@ struct sigaltstack; struct rseq; union bpf_attr; struct io_uring_params; +struct clone_args; #include #include @@ -852,6 +853,9 @@ asmlinkage long sys_clone(unsigned long, unsigned long, int __user *, int __user *, unsigned long); #endif #endif + +asmlinkage long sys_clone3(struct clone_args __user *uargs, size_t size); + asmlinkage long sys_execve(const char __user *filename, const char __user *const __user *argv, const char __user *const __user *envp); diff --git a/include/uapi/linux/sched.h b/include/uapi/linux/sched.h index ed4ee170bee2..f5331dbdcaa2 100644 --- a/include/uapi/linux/sched.h +++ b/include/uapi/linux/sched.h @@ -2,6 +2,8 @@ #ifndef _UAPI_LINUX_SCHED_H #define _UAPI_LINUX_SCHED_H +#include + /* * cloning flags: */ @@ -31,6 +33,20 @@ #define CLONE_NEWNET 0x40000000 /* New network namespace */ #define CLONE_IO 0x80000000 /* Clone io context */ +/* + * Arguments for the clone3 syscall + */ +struct clone_args { + __aligned_u64 flags; + __aligned_u64 pidfd; + __aligned_u64 child_tid; + __aligned_u64 parent_tid; + __aligned_u64 exit_signal; + __aligned_u64 stack; + __aligned_u64 stack_size; + __aligned_u64 tls; +}; + /* * Scheduling policies */ diff --git a/kernel/fork.c b/kernel/fork.c index b4cba953040a..08ff131f26b4 100644 --- a/kernel/fork.c +++ b/kernel/fork.c @@ -1760,19 +1760,15 @@ static __always_inline void delayed_free_task(struct task_struct *tsk) * flags).

These checks are only performed for CONFIG_DEBUG_VM, and the value is not used otherwise. Since we read the pte value with READ_ONCE(), the compiler cannot elide the redundant read for !CONFIG_DEBUG_VM kernels. Let's ameliorate matters by moving the read and the checks into a helper, __check_racy_pte_update(), which only performs the read when the value will be used. This also allows us to reformat the conditions for clarity.

And in commit 6bbeb276b71f ("x86/kexec: Add the EFI system tables and ACPI tables to the ident map") the ACPI tables memory region was added to the ident map. But some machines have only an ACPI NVS memory region and the ACPI tables are located in that region. In such case, the kexec-ed kernel will still fail when trying to access ACPI tables if they're not mapped. So add the NVS memory region to the ident map as well.

You should immediately see a Linux login screen. + +Here are the installation steps in detail: + + 1. The 3270 driver is a part of the official Linux kernel + source. Build a tree with the kernel source and any necessary + patches. Then do:: + + make oldconfig + (If you wish to disable 3215 console support, edit + .config; change CONFIG_TN3215's value to "n"; + and rerun "make oldconfig".) + make image + make modules + make modules_install + + 2. (Perform this step only if you have configured tub3270 as a + module.) Add a line to a file `/etc/modprobe.d/*.conf` to automatically + load the driver when it's needed. With this line added, you will see + login prompts appear on your 3270s as soon as boot is complete (or + with emulated 3270s, as soon as you dial into your vm guest using the + command "DIAL "). Since the line-mode major number is + 227, the line to add should be:: + + alias char-major-227 tub3270 + + 3. Define graphic devices to your vm guest machine, if you + haven't already. Define them before you reboot (reipl): + + - DEFINE GRAF 620 + - DEFINE GRAF 621 + - DEFINE GRAF 622 + - DEFINE GRAF 623 + + 4. Reboot. The reboot process scans hardware devices, including + 3270s, and this enables the tub3270 driver once loaded to respond + correctly to the configuration requests of the next step. If + you have chosen 3270 console support, your console now behaves + as a 3270, not a 3215. + + 5. Run the 3270 configuration script config3270. It is + distributed in this same directory, Documentation/s390, as + config3270.sh. Inspect the output script it produces, + /tmp/mkdev3270, and then run that script. This will create the + necessary character special device files and make the necessary + changes to /etc/inittab. + + Then notify /sbin/init that /etc/inittab has changed, by issuing + the telinit command with the q operand:: + + cd Documentation/s390 + sh config3270.sh + sh /tmp/mkdev3270 + telinit q + + This should be sufficient for your first time. If your 3270 + configuration has changed and you're reusing config3270, you + should follow these steps:: + + Change 3270 configuration + Reboot + Run config3270 and /tmp/mkdev3270 + Reboot + +Here are the testing steps in detail: + + 1. Bring up an x3270 window, or use an actual hardware 3278 or + 3279, or use the 3270 emulator of your choice. You would be + running the emulator on your PC or workstation. You would use + the command, for example:: + + x3270 vm-esa-domain-name & + + if you wanted a 3278 Model 4 with 43 rows of 80 columns, the + default model number. The driver does not take advantage of + extended attributes. + + The screen you should now see contains a VM logo with input + lines near the bottom. Use TAB to move to the bottom line, + probably labeled "COMMAND ===>". + + 2. Use the DIAL command instead of the LOGIN command to connect + to one of the virtual 3270s you defined with the DEF GRAF + commands:: + + dial my-vm-guest-name + + 3. You should immediately see a login prompt from your + Linux-390 operating system. If that does not happen, you would + see instead the line "DIALED TO my-vm-guest-name 0620". + + To troubleshoot: do these things. + + A. Is the driver loaded? Use the lsmod command (no operands) + to find out. Probably it isn't. Try loading it manually, with + the command "insmod tub3270". Does that command give error + messages? Ha! There's your problem. + + B. Is the /etc/inittab file modified as in installation step 3 + above? Use the grep command to find out; for instance, issue + "grep 3270 /etc/inittab". Nothing found? There's your + problem! + + C. Are the device special files created, as in installation + step 2 above? Use the ls -l command to find out; for instance, + issue "ls -l /dev/3270/tty620". The output should start with the + letter "c" meaning character device and should contain "227, 1" + just to the left of the device name. No such file? no "c"? + Wrong major number? Wrong minor number? There's your + problem! + + D. Do you get the message:: + + "HCPDIA047E my-vm-guest-name 0620 does not exist"? + + If so, you must issue the command "DEF GRAF 620" from your VM + 3215 console and then reboot the system. + + + +OPERATION. +========== + +The driver defines three areas on the 3270 screen: the log area, the +input area, and the status area. + +The log area takes up all but the bottom two lines of the screen. The +driver writes terminal output to it, starting at the top line and going +down. When it fills, the status area changes from "Linux Running" to +"Linux More...". After a scrolling timeout of (default) 5 sec, the +screen clears and more output is written, from the top down. + +The input area extends from the beginning of the second-to-last screen +line to the start of the status area. You type commands in this area +and hit ENTER to execute them. + +The status area initializes to "Linux Running" to give you a warm +fuzzy feeling. When the log area fills up and output awaits, it +changes to "Linux More...". At this time you can do several things or +nothing. If you do nothing, the screen will clear in (default) 5 sec +and more output will appear. You may hit ENTER with nothing typed in +the input area to toggle between "Linux More..." and "Linux Holding", +which indicates no scrolling will occur. (If you hit ENTER with "Linux +Running" and nothing typed, the application receives a newline.) + +You may change the scrolling timeout value. For example, the following +command line:: + + echo scrolltime=60 > /proc/tty/driver/tty3270 + +changes the scrolling timeout value to 60 sec. Set scrolltime to 0 if +you wish to prevent scrolling entirely. + +Other things you may do when the log area fills up are: hit PA2 to +clear the log area and write more output to it, or hit CLEAR to clear +the log area and the input area and write more output to the log area. + +Some of the Program Function (PF) and Program Attention (PA) keys are +preassigned special functions. The ones that are not yield an alarm +when pressed. + +PA1 causes a SIGINT to the currently running application. You may do +the same thing from the input area, by typing "^C" and hitting ENTER. + +PA2 causes the log area to be cleared. If output awaits, it is then +written to the log area. + +PF3 causes an EOF to be received as input by the application. You may +cause an EOF also by typing "^D" and hitting ENTER. + +No PF key is preassigned to cause a job suspension, but you may cause a +job suspension by typing "^Z" and hitting ENTER. You may wish to +assign this function to a PF key. To make PF7 cause job suspension, +execute the command:: + + echo pf7=^z > /proc/tty/driver/tty3270 + +If the input you type does not end with the two characters "^n", the +driver appends a newline character and sends it to the tty driver; +otherwise the driver strips the "^n" and does not append a newline. +The IBM 3215 driver behaves similarly. + +Pf10 causes the most recent command to be retrieved from the tube's +command stack (default depth 20) and displayed in the input area. You +may hit PF10 again for the next-most-recent command, and so on. A +command is entered into the stack only when the input area is not made +invisible (such as for password entry) and it is not identical to the +current top entry. PF10 rotates backward through the command stack; +PF11 rotates forward. You may assign the backward function to any PF +key (or PA key, for that matter), say, PA3, with the command:: + + echo -e pa3=\\033k > /proc/tty/driver/tty3270 + +This assigns the string ESC-k to PA3. Similarly, the string ESC-j +performs the forward function. (Rationale: In bash with vi-mode line +editing, ESC-k and ESC-j retrieve backward and forward history. +Suggestions welcome.) + +Is a stack size of twenty commands not to your liking? Change it on +the fly. To change to saving the last 100 commands, execute the +command:: + + echo recallsize=100 > /proc/tty/driver/tty3270 + +Have a command you issue frequently? Assign it to a PF or PA key! Use +the command:: + + echo pf24="mkdir foobar; cd foobar" > /proc/tty/driver/tty3270 + +to execute the commands mkdir foobar and cd foobar immediately when you +hit PF24. Want to see the command line first, before you execute it? +Use the -n option of the echo command:: + + echo -n pf24="mkdir foo; cd foo" > /proc/tty/driver/tty3270 + + + +Happy testing!

It usually is fairly consistent & similar from -function to function & if you know its layout you can probably -make some headway in finding the ultimate cause of a problem -after a crash without a source level debugger. - -Note: To follow stackframes requires a knowledge of C or Pascal & -limited knowledge of one assembly language. - -It should be noted that there are some differences between the -s/390 and z/Architecture stack layouts as the z/Architecture stack layout -didn't have to maintain compatibility with older linkage formats. - -Glossary: ---------- -alloca: -This is a built in compiler function for runtime allocation -of extra space on the callers stack which is obviously freed -up on function exit ( e.g. the caller may choose to allocate nothing -of a buffer of 4k if required for temporary purposes ), it generates -very efficient code ( a few cycles ) when compared to alternatives -like malloc. - -automatics: These are local variables on the stack, -i.e they aren't in registers & they aren't static. - -back-chain: -This is a pointer to the stack pointer before entering a -framed functions ( see frameless function ) prologue got by -dereferencing the address of the current stack pointer, - i.e. got by accessing the 32 bit value at the stack pointers -current location. - -base-pointer: -This is a pointer to the back of the literal pool which -is an area just behind each procedure used to store constants -in each function. - -call-clobbered: The caller probably needs to save these registers if there -is something of value in them, on the stack or elsewhere before making a -call to another procedure so that it can restore it later. - -epilogue: -The code generated by the compiler to return to the caller. - -frameless-function -A frameless function in Linux for s390 & z/Architecture is one which doesn't -need more than the register save area (96 bytes on s/390, 160 on z/Architecture) -given to it by the caller. -A frameless function never: -1) Sets up a back chain. -2) Calls alloca. -3) Calls other normal functions -4) Has automatics. - -GOT-pointer: -This is a pointer to the global-offset-table in ELF -( Executable Linkable Format, Linux'es most common executable format ), -all globals & shared library objects are found using this pointer. - -lazy-binding -ELF shared libraries are typically only loaded when routines in the shared -library are actually first called at runtime. This is lazy binding. - -procedure-linkage-table -This is a table found from the GOT which contains pointers to routines -in other shared libraries which can't be called to by easier means. - -prologue: -The code generated by the compiler to set up the stack frame. - -outgoing-args: -This is extra area allocated on the stack of the calling function if the -parameters for the callee's cannot all be put in registers, the same -area can be reused by each function the caller calls. - -routine-descriptor: -A COFF executable format based concept of a procedure reference -actually being 8 bytes or more as opposed to a simple pointer to the routine. -This is typically defined as follows -Routine Descriptor offset 0=Pointer to Function -Routine Descriptor offset 4=Pointer to Table of Contents -The table of contents/TOC is roughly equivalent to a GOT pointer. -& it means that shared libraries etc. can be shared between several -environments each with their own TOC. - - -static-chain: This is used in nested functions a concept adopted from pascal -by gcc not used in ansi C or C++ ( although quite useful ), basically it -is a pointer used to reference local variables of enclosing functions. -You might come across this stuff once or twice in your lifetime. - -e.g. -The function below should return 11 though gcc may get upset & toss warnings -about unused variables. -int FunctionA(int a) -{ - int b; - FunctionC(int c) - { - b=c+1; - } - FunctionC(10); - return(b); -} - - -s/390 & z/Architecture Register usage -===================================== -r0 used by syscalls/assembly call-clobbered -r1 used by syscalls/assembly call-clobbered -r2 argument 0 / return value 0 call-clobbered -r3 argument 1 / return value 1 (if long long) call-clobbered -r4 argument 2 call-clobbered -r5 argument 3 call-clobbered -r6 argument 4 saved -r7 pointer-to arguments 5 to ... saved -r8 this & that saved -r9 this & that saved -r10 static-chain ( if nested function ) saved -r11 frame-pointer ( if function used alloca ) saved -r12 got-pointer saved -r13 base-pointer saved -r14 return-address saved -r15 stack-pointer saved - -f0 argument 0 / return value ( float/double ) call-clobbered -f2 argument 1 call-clobbered -f4 z/Architecture argument 2 saved -f6 z/Architecture argument 3 saved -The remaining floating points -f1,f3,f5 f7-f15 are call-clobbered. - -Notes: ------- -1) The only requirement is that registers which are used -by the callee are saved, e.g. the compiler is perfectly -capable of using r11 for purposes other than a frame a -frame pointer if a frame pointer is not needed. -2) In functions with variable arguments e.g. printf the calling procedure -is identical to one without variable arguments & the same number of -parameters. However, the prologue of this function is somewhat more -hairy owing to it having to move these parameters to the stack to -get va_start, va_arg & va_end to work. -3) Access registers are currently unused by gcc but are used in -the kernel. Possibilities exist to use them at the moment for -temporary storage but it isn't recommended. -4) Only 4 of the floating point registers are used for -parameter passing as older machines such as G3 only have only 4 -& it keeps the stack frame compatible with other compilers. -However with IEEE floating point emulation under linux on the -older machines you are free to use the other 12. -5) A long long or double parameter cannot be have the -first 4 bytes in a register & the second four bytes in the -outgoing args area. It must be purely in the outgoing args -area if crossing this boundary. -6) Floating point parameters are mixed with outgoing args -on the outgoing args area in the order the are passed in as parameters. -7) Floating point arguments 2 & 3 are saved in the outgoing args area for -z/Architecture - - -Stack Frame Layout ------------------- -s/390 z/Architecture -0 0 back chain ( a 0 here signifies end of back chain ) -4 8 eos ( end of stack, not used on Linux for S390 used in other linkage formats ) -8 16 glue used in other s/390 linkage formats for saved routine descriptors etc. -12 24 glue used in other s/390 linkage formats for saved routine descriptors etc. -16 32 scratch area -20 40 scratch area -24 48 saved r6 of caller function -28 56 saved r7 of caller function -32 64 saved r8 of caller function -36 72 saved r9 of caller function -40 80 saved r10 of caller function -44 88 saved r11 of caller function -48 96 saved r12 of caller function -52 104 saved r13 of caller function -56 112 saved r14 of caller function -60 120 saved r15 of caller function -64 128 saved f4 of caller function -72 132 saved f6 of caller function -80 undefined -96 160 outgoing args passed from caller to callee -96+x 160+x possible stack alignment ( 8 bytes desirable ) -96+x+y 160+x+y alloca space of caller ( if used ) -96+x+y+z 160+x+y+z automatics of caller ( if used ) -0 back-chain - -A sample program with comments. -=============================== - -Comments on the function test ------------------------------ -1) It didn't need to set up a pointer to the constant pool gpr13 as it is not -used ( :-( ). -2) This is a frameless function & no stack is bought. -3) The compiler was clever enough to recognise that it could return the -value in r2 as well as use it for the passed in parameter ( :-) ). -4) The basr ( branch relative & save ) trick works as follows the instruction -has a special case with r0,r0 with some instruction operands is understood as -the literal value 0, some risc architectures also do this ). So now -we are branching to the next address & the address new program counter is -in r13,so now we subtract the size of the function prologue we have executed -+ the size of the literal pool to get to the top of the literal pool -0040037c int test(int b) -{ # Function prologue below - 40037c: 90 de f0 34 stm %r13,%r14,52(%r15) # Save registers r13 & r14 - 400380: 0d d0 basr %r13,%r0 # Set up pointer to constant pool using - 400382: a7 da ff fa ahi %r13,-6 # basr trick - return(5+b); - # Huge main program - 400386: a7 2a 00 05 ahi %r2,5 # add 5 to r2 - - # Function epilogue below - 40038a: 98 de f0 34 lm %r13,%r14,52(%r15) # restore registers r13 & 14 - 40038e: 07 fe br %r14 # return -} - -Comments on the function main ------------------------------ -1) The compiler did this function optimally ( 8-) ) - -Literal pool for main. -400390: ff ff ff ec .long 0xffffffec -main(int argc,char *argv[]) -{ # Function prologue below - 400394: 90 bf f0 2c stm %r11,%r15,44(%r15) # Save necessary registers - 400398: 18 0f lr %r0,%r15 # copy stack pointer to r0 - 40039a: a7 fa ff a0 ahi %r15,-96 # Make area for callee saving - 40039e: 0d d0 basr %r13,%r0 # Set up r13 to point to - 4003a0: a7 da ff f0 ahi %r13,-16 # literal pool - 4003a4: 50 00 f0 00 st %r0,0(%r15) # Save backchain - - return(test(5)); # Main Program Below - 4003a8: 58 e0 d0 00 l %r14,0(%r13) # load relative address of test from - # literal pool - 4003ac: a7 28 00 05 lhi %r2,5 # Set first parameter to 5 - 4003b0: 4d ee d0 00 bas %r14,0(%r14,%r13) # jump to test setting r14 as return - # address using branch & save instruction. - - # Function Epilogue below - 4003b4: 98 bf f0 8c lm %r11,%r15,140(%r15)# Restore necessary registers. - 4003b8: 07 fe br %r14 # return to do program exit -} - - -Compiler updates ----------------- - -main(int argc,char *argv[]) -{ - 4004fc: 90 7f f0 1c stm %r7,%r15,28(%r15) - 400500: a7 d5 00 04 bras %r13,400508 - 400504: 00 40 04 f4 .long 0x004004f4 - # compiler now puts constant pool in code to so it saves an instruction - 400508: 18 0f lr %r0,%r15 - 40050a: a7 fa ff a0 ahi %r15,-96 - 40050e: 50 00 f0 00 st %r0,0(%r15) - return(test(5)); - 400512: 58 10 d0 00 l %r1,0(%r13) - 400516: a7 28 00 05 lhi %r2,5 - 40051a: 0d e1 basr %r14,%r1 - # compiler adds 1 extra instruction to epilogue this is done to - # avoid processor pipeline stalls owing to data dependencies on g5 & - # above as register 14 in the old code was needed directly after being loaded - # by the lm %r11,%r15,140(%r15) for the br %14. - 40051c: 58 40 f0 98 l %r4,152(%r15) - 400520: 98 7f f0 7c lm %r7,%r15,124(%r15) - 400524: 07 f4 br %r4 -} - - -Hartmut ( our compiler developer ) also has been threatening to take out the -stack backchain in optimised code as this also causes pipeline stalls, you -have been warned. - -64 bit z/Architecture code disassembly --------------------------------------- - -If you understand the stuff above you'll understand the stuff -below too so I'll avoid repeating myself & just say that -some of the instructions have g's on the end of them to indicate -they are 64 bit & the stack offsets are a bigger, -the only other difference you'll find between 32 & 64 bit is that -we now use f4 & f6 for floating point arguments on 64 bit. -00000000800005b0 : -int test(int b) -{ - return(5+b); - 800005b0: a7 2a 00 05 ahi %r2,5 - 800005b4: b9 14 00 22 lgfr %r2,%r2 # downcast to integer - 800005b8: 07 fe br %r14 - 800005ba: 07 07 bcr 0,%r7 - - -} - -00000000800005bc

For kernel hacking you will reap dividends if -you get good at it. - -The VM Debugger displays operators but not operands, and also the debugger -displays useful information on the same line as the author of the code probably -felt that it was a good idea not to go over the 80 columns on the screen. -This isn't as unintuitive as it may seem as the s/390 instructions are easy to -decode mentally and you can make a good guess at a lot of them as all the -operands are nibble (half byte aligned). -So if you have an objdump listing by hand, it is quite easy to follow, and if -you don't have an objdump listing keep a copy of the s/390 Reference Summary -or alternatively the s/390 principles of operation next to you. -e.g. even I can guess that -0001AFF8' LR 180F CC 0 -is a ( load register ) lr r0,r15 - -Also it is very easy to tell the length of a 390 instruction from the 2 most -significant bits in the instruction (not that this info is really useful except -if you are trying to make sense of a hexdump of code). -Here is a table -Bits Instruction Length ------------------------------------------- -00 2 Bytes -01 4 Bytes -10 4 Bytes -11 6 Bytes - -The debugger also displays other useful info on the same line such as the -addresses being operated on destination addresses of branches & condition codes. -e.g. -00019736' AHI A7DAFF0E CC 1 -000198BA' BRC A7840004 -> 000198C2' CC 0 -000198CE' STM 900EF068 >> 0FA95E78 CC 2 - - - -Useful VM debugger commands ---------------------------- - -I suppose I'd better mention this before I start -to list the current active traces do -Q TR -there can be a maximum of 255 of these per set -( more about trace sets later ). -To stop traces issue a -TR END. -To delete a particular breakpoint issue -TR DEL - -The PA1 key drops to CP mode so you can issue debugger commands, -Doing alt c (on my 3270 console at least ) clears the screen. -hitting b comes back to the running operating system -from cp mode ( in our case linux ). -It is typically useful to add shortcuts to your profile.exec file -if you have one ( this is roughly equivalent to autoexec.bat in DOS ). -file here are a few from mine. -/* this gives me command history on issuing f12 */ -set pf12 retrieve -/* this continues */ -set pf8 imm b -/* goes to trace set a */ -set pf1 imm tr goto a -/* goes to trace set b */ -set pf2 imm tr goto b -/* goes to trace set c */ -set pf3 imm tr goto c - - - -Instruction Tracing -------------------- -Setting a simple breakpoint -TR I PSWA

-for finding out when a particular variable changes. - -An alternative way of finding the STD of a currently running process -is to do the following, ( this method is more complex but -could be quite convenient if you aren't updating the kernel much & -so your kernel structures will stay constant for a reasonable period of -time ). - -grep task /proc//status -from this you should see something like -task: 0f160000 ksp: 0f161de8 pt_regs: 0f161f68 -This now gives you a pointer to the task structure. -Now make CC:="s390-gcc -g" kernel/sched.s -To get the task_struct stabinfo. -( task_struct is defined in include/linux/sched.h ). -Now we want to look at -task->active_mm->pgd -on my machine the active_mm in the task structure stab is -active_mm:(4,12),672,32 -its offset is 672/8=84=0x54 -the pgd member in the mm_struct stab is -pgd:(4,6)=*(29,5),96,32 -so its offset is 96/8=12=0xc - -so we'll -hexdump -s 0xf160054 /dev/mem | more -i.e. task_struct+active_mm offset -to look at the active_mm member -f160054 0fee cc60 0019 e334 0000 0000 0000 0011 -hexdump -s 0x0feecc6c /dev/mem | more -i.e. active_mm+pgd offset -feecc6c 0f2c 0000 0000 0001 0000 0001 0000 0010 -we get something like -now do -TR I R STD 0.7fffffff -i.e. the 0x7f is added because the pgd only -gives the page table origin & we need to set the low bits -to the maximum possible segment table length. -TR I R STD 0f2c007f 0.7fffffff -on z/Architecture you'll probably need to do -TR I R STD 0.ffffffffffffffff -to set the TableType to 0x1 & the Table length to 3. - - - -Tracing Program Exceptions --------------------------- -If you get a crash which says something like -illegal operation or specification exception followed by a register dump -You can restart linux & trace these using the tr prog trace -option. - - -The most common ones you will normally be tracing for is -1=operation exception -2=privileged operation exception -4=protection exception -5=addressing exception -6=specification exception -10=segment translation exception -11=page translation exception - -The full list of these is on page 22 of the current s/390 Reference Summary. -e.g. -tr prog 10 will trace segment translation exceptions. -tr prog on its own will trace all program interruption codes. - -Trace Sets ----------- -On starting VM you are initially in the INITIAL trace set. -You can do a Q TR to verify this. -If you have a complex tracing situation where you wish to wait for instance -till a driver is open before you start tracing IO, but know in your -heart that you are going to have to make several runs through the code till you -have a clue whats going on. - -What you can do is -TR I PSWA -hit b to continue till breakpoint -reach the breakpoint -now do your -TR GOTO B -TR IO 7c08-7c09 inst int run -or whatever the IO channels you wish to trace are & hit b - -To got back to the initial trace set do -TR GOTO INITIAL -& the TR I PSWA will be the only active breakpoint again. - - -Tracing linux syscalls under VM -------------------------------- -Syscalls are implemented on Linux for S390 by the Supervisor call instruction -(SVC).

Instead I'll give a 390 IO architecture -summary for Dummies. If you have the s/390 principles of operation available -read this instead. If nothing else you may find a few useful keywords in here -and be able to use them on a web search engine to find more useful information. - -Unlike other bus architectures modern 390 systems do their IO using mostly -fibre optics and devices such as tapes and disks can be shared between several -mainframes. Also S390 can support up to 65536 devices while a high end PC based -system might be choking with around 64. - -Here is some of the common IO terminology: - -Subchannel: -This is the logical number most IO commands use to talk to an IO device. There -can be up to 0x10000 (65536) of these in a configuration, typically there are a -few hundred. Under VM for simplicity they are allocated contiguously, however -on the native hardware they are not. They typically stay consistent between -boots provided no new hardware is inserted or removed. -Under Linux for s390 we use these as IRQ's and also when issuing an IO command -(CLEAR SUBCHANNEL, HALT SUBCHANNEL, MODIFY SUBCHANNEL, RESUME SUBCHANNEL, -START SUBCHANNEL, STORE SUBCHANNEL and TEST SUBCHANNEL). We use this as the ID -of the device we wish to talk to. The most important of these instructions are -START SUBCHANNEL (to start IO), TEST SUBCHANNEL (to check whether the IO -completed successfully) and HALT SUBCHANNEL (to kill IO). A subchannel can have -up to 8 channel paths to a device, this offers redundancy if one is not -available. - -Device Number: -This number remains static and is closely tied to the hardware. There are 65536 -of these, made up of a CHPID (Channel Path ID, the most significant 8 bits) and -another lsb 8 bits. These remain static even if more devices are inserted or -removed from the hardware. There is a 1 to 1 mapping between subchannels and -device numbers, provided devices aren't inserted or removed. - -Channel Control Words: -CCWs are linked lists of instructions initially pointed to by an operation -request block (ORB), which is initially given to Start Subchannel (SSCH) -command along with the subchannel number for the IO subsystem to process -while the CPU continues executing normal code. -CCWs come in two flavours, Format 0 (24 bit for backward compatibility) and -Format 1 (31 bit). These are typically used to issue read and write (and many -other) instructions. They consist of a length field and an absolute address -field. -Each IO typically gets 1 or 2 interrupts, one for channel end (primary status) -when the channel is idle, and the second for device end (secondary status). -Sometimes you get both concurrently. You check how the IO went on by issuing a -TEST SUBCHANNEL at each interrupt, from which you receive an Interruption -response block (IRB). If you get channel and device end status in the IRB -without channel checks etc. your IO probably went okay. If you didn't you -probably need to examine the IRB, extended status word etc. -If an error occurs, more sophisticated control units have a facility known as -concurrent sense. This means that if an error occurs Extended sense information -will be presented in the Extended status word in the IRB. If not you have to -issue a subsequent SENSE CCW command after the test subchannel. - - -TPI (Test pending interrupt) can also be used for polled IO, but in -multitasking multiprocessor systems it isn't recommended except for -checking special cases (i.e. non looping checks for pending IO etc.). - -Store Subchannel and Modify Subchannel can be used to examine and modify -operating characteristics of a subchannel (e.g. channel paths). - -Other IO related Terms: -Sysplex: S390's Clustering Technology -QDIO: S390's new high speed IO architecture to support devices such as gigabit -ethernet, this architecture is also designed to be forward compatible with -upcoming 64 bit machines. - - -General Concepts - -Input Output Processors (IOP's) are responsible for communicating between -the mainframe CPU's & the channel & relieve the mainframe CPU's from the -burden of communicating with IO devices directly, this allows the CPU's to -concentrate on data processing. - -IOP's can use one or more links ( known as channel paths ) to talk to each -IO device. It first checks for path availability & chooses an available one, -then starts ( & sometimes terminates IO ). -There are two types of channel path: ESCON & the Parallel IO interface. - -IO devices are attached to control units, control units provide the -logic to interface the channel paths & channel path IO protocols to -the IO devices, they can be integrated with the devices or housed separately -& often talk to several similar devices ( typical examples would be raid -controllers or a control unit which connects to 1000 3270 terminals ). - - - +---------------------------------------------------------------+ - | +-----+ +-----+ +-----+ +-----+ +----------+ +----------+ | - | | CPU | | CPU | | CPU | | CPU | | Main | | Expanded | | - | | | | | | | | | | Memory | | Storage | | - | +-----+ +-----+ +-----+ +-----+ +----------+ +----------+ | - |---------------------------------------------------------------+ - | IOP | IOP | IOP | - |--------------------------------------------------------------- - | C | C | C | C | C | C | C | C | C | C | C | C | C | C | C | C | - ---------------------------------------------------------------- - || || - || Bus & Tag Channel Path || ESCON - || ====================== || Channel - || || || || Path - +----------+ +----------+ +----------+ - | | | | | | - | CU | | CU | | CU | - | | | | | | - +----------+ +----------+ +----------+ - | | | | | -+----------+ +----------+ +----------+ +----------+ +----------+ -|I/O Device| |I/O Device| |I/O Device| |I/O Device| |I/O Device| -+----------+ +----------+ +----------+ +----------+ +----------+ - CPU = Central Processing Unit - C = Channel - IOP = IP Processor - CU = Control Unit - -The 390 IO systems come in 2 flavours the current 390 machines support both - -The Older 360 & 370 Interface,sometimes called the Parallel I/O interface, -sometimes called Bus-and Tag & sometimes Original Equipment Manufacturers -Interface (OEMI). - -This byte wide Parallel channel path/bus has parity & data on the "Bus" cable -and control lines on the "Tag" cable. These can operate in byte multiplex mode -for sharing between several slow devices or burst mode and monopolize the -channel for the whole burst. Up to 256 devices can be addressed on one of these -cables. These cables are about one inch in diameter. The maximum unextended -length supported by these cables is 125 Meters but this can be extended up to -2km with a fibre optic channel extended such as a 3044. The maximum burst speed -supported is 4.5 megabytes per second. However, some really old processors -support only transfer rates of 3.0, 2.0 & 1.0 MB/sec. -One of these paths can be daisy chained to up to 8 control units. - - -ESCON if fibre optic it is also called FICON -Was introduced by IBM in 1990. Has 2 fibre optic cables and uses either leds or -lasers for communication at a signaling rate of up to 200 megabits/sec. As -10bits are transferred for every 8 bits info this drops to 160 megabits/sec -and to 18.6 Megabytes/sec once control info and CRC are added. ESCON only -operates in burst mode. - -ESCONs typical max cable length is 3km for the led version and 20km for the -laser version known as XDF (extended distance facility). This can be further -extended by using an ESCON director which triples the above mentioned ranges. -Unlike Bus & Tag as ESCON is serial it uses a packet switching architecture, -the standard Bus & Tag control protocol is however present within the packets. -Up to 256 devices can be attached to each control unit that uses one of these -interfaces. - -Common 390 Devices include: -Network adapters typically OSA2,3172's,2116's & OSA-E gigabit ethernet adapters, -Consoles 3270 & 3215 (a teletype emulated under linux for a line mode console). -DASD's direct access storage devices ( otherwise known as hard disks ). -Tape Drives. -CTC ( Channel to Channel Adapters ), -ESCON or Parallel Cables used as a very high speed serial link -between 2 machines. - - -Debugging IO on s/390 & z/Architecture under VM -=============================================== - -Now we are ready to go on with IO tracing commands under VM - -A few self explanatory queries: -Q OSA -Q CTC -Q DISK ( This command is CMS specific ) -Q DASD - - - - - - -Q OSA on my machine returns -OSA 7C08 ON OSA 7C08 SUBCHANNEL = 0000 -OSA 7C09 ON OSA 7C09 SUBCHANNEL = 0001 -OSA 7C14 ON OSA 7C14 SUBCHANNEL = 0002 -OSA 7C15 ON OSA 7C15 SUBCHANNEL = 0003 - -If you have a guest with certain privileges you may be able to see devices -which don't belong to you.

This gives relief to the device drivers as they don't +have to deal with different bus types, polling versus interrupt +processing, shared versus non-shared interrupt processing, DMA versus port +I/O (PIO), and other hardware features more. However, this implies that +either every single device driver needs to implement the hardware I/O +attachment functionality itself, or the operating system provides for a +unified method to access the hardware, providing all the functionality that +every single device driver would have to provide itself. + +The document does not intend to explain the ESA/390 hardware architecture in +every detail.This information can be obtained from the ESA/390 Principles of +Operation manual (IBM Form. No. SA22-7201). + +In order to build common device support for ESA/390 I/O interfaces, a +functional layer was introduced that provides generic I/O access methods to +the hardware. + +The common device support layer comprises the I/O support routines defined +below. Some of them implement common Linux device driver interfaces, while +some of them are ESA/390 platform specific. + +Note: + In order to write a driver for S/390, you also need to look into the interface + described in Documentation/s390/driver-model.rst. + +Note for porting drivers from 2.4: + +The major changes are: + +* The functions use a ccw_device instead of an irq (subchannel). +* All drivers must define a ccw_driver (see driver-model.txt) and the associated + functions. +* request_irq() and free_irq() are no longer done by the driver. +* The oper_handler is (kindof) replaced by the probe() and set_online() functions + of the ccw_driver. +* The not_oper_handler is (kindof) replaced by the remove() and set_offline() + functions of the ccw_driver. +* The channel device layer is gone. +* The interrupt handlers must be adapted to use a ccw_device as argument. + Moreover, they don't return a devstat, but an irb. +* Before initiating an io, the options must be set via ccw_device_set_options(). +* Instead of calling read_dev_chars()/read_conf_data(), the driver issues + the channel program and handles the interrupt itself. + +ccw_device_get_ciw() + get commands from extended sense data. + +ccw_device_start(), ccw_device_start_timeout(), ccw_device_start_key(), ccw_device_start_key_timeout() + initiate an I/O request. + +ccw_device_resume() + resume channel program execution. + +ccw_device_halt() + terminate the current I/O request processed on the device. + +do_IRQ() + generic interrupt routine. This function is called by the interrupt entry + routine whenever an I/O interrupt is presented to the system. The do_IRQ() + routine determines the interrupt status and calls the device specific + interrupt handler according to the rules (flags) defined during I/O request + initiation with do_IO(). + +The next chapters describe the functions other than do_IRQ() in more details. +The do_IRQ() interface is not described, as it is called from the Linux/390 +first level interrupt handler only and does not comprise a device driver +callable interface. Instead, the functional description of do_IO() also +describes the input to the device specific interrupt handler. + +Note: + All explanations apply also to the 64 bit architecture s390x. + + +Common Device Support (CDS) for Linux/390 Device Drivers +======================================================== + +General Information +------------------- + +The following chapters describe the I/O related interface routines the +Linux/390 common device support (CDS) provides to allow for device specific +driver implementations on the IBM ESA/390 hardware platform. Those interfaces +intend to provide the functionality required by every device driver +implementation to allow to drive a specific hardware device on the ESA/390 +platform. Some of the interface routines are specific to Linux/390 and some +of them can be found on other Linux platforms implementations too. +Miscellaneous function prototypes, data declarations, and macro definitions +can be found in the architecture specific C header file +linux/arch/s390/include/asm/irq.h. + +Overview of CDS interface concepts +---------------------------------- + +Different to other hardware platforms, the ESA/390 architecture doesn't define +interrupt lines managed by a specific interrupt controller and bus systems +that may or may not allow for shared interrupts, DMA processing, etc.. Instead, +the ESA/390 architecture has implemented a so called channel subsystem, that +provides a unified view of the devices physically attached to the systems. +Though the ESA/390 hardware platform knows about a huge variety of different +peripheral attachments like disk devices (aka. DASDs), tapes, communication +controllers, etc. they can all be accessed by a well defined access method and +they are presenting I/O completion a unified way : I/O interruptions. Every +single device is uniquely identified to the system by a so called subchannel, +where the ESA/390 architecture allows for 64k devices be attached. + +Linux, however, was first built on the Intel PC architecture, with its two +cascaded 8259 programmable interrupt controllers (PICs), that allow for a +maximum of 15 different interrupt lines. All devices attached to such a system +share those 15 interrupt levels. Devices attached to the ISA bus system must +not share interrupt levels (aka. IRQs), as the ISA bus bases on edge triggered +interrupts. MCA, EISA, PCI and other bus systems base on level triggered +interrupts, and therewith allow for shared IRQs. However, if multiple devices +present their hardware status by the same (shared) IRQ, the operating system +has to call every single device driver registered on this IRQ in order to +determine the device driver owning the device that raised the interrupt. + +Up to kernel 2.4, Linux/390 used to provide interfaces via the IRQ (subchannel). +For internal use of the common I/O layer, these are still there. However, +device drivers should use the new calling interface via the ccw_device only. + +During its startup the Linux/390 system checks for peripheral devices. Each +of those devices is uniquely defined by a so called subchannel by the ESA/390 +channel subsystem. While the subchannel numbers are system generated, each +subchannel also takes a user defined attribute, the so called device number. +Both subchannel number and device number cannot exceed 65535. During sysfs +initialisation, the information about control unit type and device types that +imply specific I/O commands (channel command words - CCWs) in order to operate +the device are gathered. Device drivers can retrieve this set of hardware +information during their initialization step to recognize the devices they +support using the information saved in the struct ccw_device given to them. +This methods implies that Linux/390 doesn't require to probe for free (not +armed) interrupt request lines (IRQs) to drive its devices with. Where +applicable, the device drivers can use issue the READ DEVICE CHARACTERISTICS +ccw to retrieve device characteristics in its online routine. + +In order to allow for easy I/O initiation the CDS layer provides a +ccw_device_start() interface that takes a device specific channel program (one +or more CCWs) as input sets up the required architecture specific control blocks +and initiates an I/O request on behalf of the device driver. The +ccw_device_start() routine allows to specify whether it expects the CDS layer +to notify the device driver for every interrupt it observes, or with final status +only. See ccw_device_start() for more details. A device driver must never issue +ESA/390 I/O commands itself, but must use the Linux/390 CDS interfaces instead. + +For long running I/O request to be canceled, the CDS layer provides the +ccw_device_halt() function. Some devices require to initially issue a HALT +SUBCHANNEL (HSCH) command without having pending I/O requests. This function is +also covered by ccw_device_halt(). + + +get_ciw() - get command information word + +This call enables a device driver to get information about supported commands +from the extended SenseID data. + +:: + + struct ciw * + ccw_device_get_ciw(struct ccw_device *cdev, __u32 cmd); + +==== ======================================================== +cdev The ccw_device for which the command is to be retrieved. +cmd The command type to be retrieved. +==== ======================================================== + +ccw_device_get_ciw() returns: + +===== ================================================================ + NULL No extended data available, invalid device or command not found. +!NULL The command requested. +===== ================================================================ + +:: + + ccw_device_start() - Initiate I/O Request + +The ccw_device_start() routines is the I/O request front-end processor. All +device driver I/O requests must be issued using this routine. A device driver +must not issue ESA/390 I/O commands itself. Instead the ccw_device_start() +routine provides all interfaces required to drive arbitrary devices. + +This description also covers the status information passed to the device +driver's interrupt handler as this is related to the rules (flags) defined +with the associated I/O request when calling ccw_device_start(). + +:: + + int ccw_device_start(struct ccw_device *cdev, + struct ccw1 *cpa, + unsigned long intparm, + __u8 lpm, + unsigned long flags); + int ccw_device_start_timeout(struct ccw_device *cdev, + struct ccw1 *cpa, + unsigned long intparm, + __u8 lpm, + unsigned long flags, + int expires); + int ccw_device_start_key(struct ccw_device *cdev, + struct ccw1 *cpa, + unsigned long intparm, + __u8 lpm, + __u8 key, + unsigned long flags); + int ccw_device_start_key_timeout(struct ccw_device *cdev, + struct ccw1 *cpa, + unsigned long intparm, + __u8 lpm, + __u8 key, + unsigned long flags, + int expires); + +============= ============================================================= +cdev ccw_device the I/O is destined for +cpa logical start address of channel program +user_intparm user specific interrupt information; will be presented + back to the device driver's interrupt handler.

No. SA22-7201). - -In order to build common device support for ESA/390 I/O interfaces, a -functional layer was introduced that provides generic I/O access methods to -the hardware. - -The common device support layer comprises the I/O support routines defined -below. Some of them implement common Linux device driver interfaces, while -some of them are ESA/390 platform specific. - -Note: -In order to write a driver for S/390, you also need to look into the interface -described in Documentation/s390/driver-model.txt. - -Note for porting drivers from 2.4: -The major changes are: -* The functions use a ccw_device instead of an irq (subchannel). -* All drivers must define a ccw_driver (see driver-model.txt) and the associated - functions. -* request_irq() and free_irq() are no longer done by the driver. -* The oper_handler is (kindof) replaced by the probe() and set_online() functions - of the ccw_driver. -* The not_oper_handler is (kindof) replaced by the remove() and set_offline() - functions of the ccw_driver. -* The channel device layer is gone. -* The interrupt handlers must be adapted to use a ccw_device as argument. - Moreover, they don't return a devstat, but an irb. -* Before initiating an io, the options must be set via ccw_device_set_options(). -* Instead of calling read_dev_chars()/read_conf_data(), the driver issues - the channel program and handles the interrupt itself. - -ccw_device_get_ciw() - get commands from extended sense data. - -ccw_device_start() -ccw_device_start_timeout() -ccw_device_start_key() -ccw_device_start_key_timeout() - initiate an I/O request. - -ccw_device_resume() - resume channel program execution. - -ccw_device_halt() - terminate the current I/O request processed on the device. - -do_IRQ() - generic interrupt routine. This function is called by the interrupt entry - routine whenever an I/O interrupt is presented to the system. The do_IRQ() - routine determines the interrupt status and calls the device specific - interrupt handler according to the rules (flags) defined during I/O request - initiation with do_IO(). - -The next chapters describe the functions other than do_IRQ() in more details. -The do_IRQ() interface is not described, as it is called from the Linux/390 -first level interrupt handler only and does not comprise a device driver -callable interface. Instead, the functional description of do_IO() also -describes the input to the device specific interrupt handler. - -Note: All explanations apply also to the 64 bit architecture s390x. - - -Common Device Support (CDS) for Linux/390 Device Drivers - -General Information - -The following chapters describe the I/O related interface routines the -Linux/390 common device support (CDS) provides to allow for device specific -driver implementations on the IBM ESA/390 hardware platform. Those interfaces -intend to provide the functionality required by every device driver -implementation to allow to drive a specific hardware device on the ESA/390 -platform. Some of the interface routines are specific to Linux/390 and some -of them can be found on other Linux platforms implementations too. -Miscellaneous function prototypes, data declarations, and macro definitions -can be found in the architecture specific C header file -linux/arch/s390/include/asm/irq.h. - -Overview of CDS interface concepts - -Different to other hardware platforms, the ESA/390 architecture doesn't define -interrupt lines managed by a specific interrupt controller and bus systems -that may or may not allow for shared interrupts, DMA processing, etc.. Instead, -the ESA/390 architecture has implemented a so called channel subsystem, that -provides a unified view of the devices physically attached to the systems. -Though the ESA/390 hardware platform knows about a huge variety of different -peripheral attachments like disk devices (aka. DASDs), tapes, communication -controllers, etc. they can all be accessed by a well defined access method and -they are presenting I/O completion a unified way : I/O interruptions. Every -single device is uniquely identified to the system by a so called subchannel, -where the ESA/390 architecture allows for 64k devices be attached. - -Linux, however, was first built on the Intel PC architecture, with its two -cascaded 8259 programmable interrupt controllers (PICs), that allow for a -maximum of 15 different interrupt lines. All devices attached to such a system -share those 15 interrupt levels. Devices attached to the ISA bus system must -not share interrupt levels (aka. IRQs), as the ISA bus bases on edge triggered -interrupts. MCA, EISA, PCI and other bus systems base on level triggered -interrupts, and therewith allow for shared IRQs. However, if multiple devices -present their hardware status by the same (shared) IRQ, the operating system -has to call every single device driver registered on this IRQ in order to -determine the device driver owning the device that raised the interrupt. - -Up to kernel 2.4, Linux/390 used to provide interfaces via the IRQ (subchannel). -For internal use of the common I/O layer, these are still there. However, -device drivers should use the new calling interface via the ccw_device only. - -During its startup the Linux/390 system checks for peripheral devices. Each -of those devices is uniquely defined by a so called subchannel by the ESA/390 -channel subsystem. While the subchannel numbers are system generated, each -subchannel also takes a user defined attribute, the so called device number. -Both subchannel number and device number cannot exceed 65535. During sysfs -initialisation, the information about control unit type and device types that -imply specific I/O commands (channel command words - CCWs) in order to operate -the device are gathered. Device drivers can retrieve this set of hardware -information during their initialization step to recognize the devices they -support using the information saved in the struct ccw_device given to them. -This methods implies that Linux/390 doesn't require to probe for free (not -armed) interrupt request lines (IRQs) to drive its devices with. Where -applicable, the device drivers can use issue the READ DEVICE CHARACTERISTICS -ccw to retrieve device characteristics in its online routine. - -In order to allow for easy I/O initiation the CDS layer provides a -ccw_device_start() interface that takes a device specific channel program (one -or more CCWs) as input sets up the required architecture specific control blocks -and initiates an I/O request on behalf of the device driver. The -ccw_device_start() routine allows to specify whether it expects the CDS layer -to notify the device driver for every interrupt it observes, or with final status -only. See ccw_device_start() for more details. A device driver must never issue -ESA/390 I/O commands itself, but must use the Linux/390 CDS interfaces instead. - -For long running I/O request to be canceled, the CDS layer provides the -ccw_device_halt() function. Some devices require to initially issue a HALT -SUBCHANNEL (HSCH) command without having pending I/O requests.

It is valid for all types of DASDs and represents them to +Linux as block devices, namely "dd". Currently the DASD driver uses a +single major number (254) and 4 minor numbers per volume (1 for the +physical volume and 3 for partitions). With respect to partitions see +below. Thus you may have up to 64 DASD devices in your system. + +The kernel parameter 'dasd=from-to,...' may be issued arbitrary times +in the kernel's parameter line or not at all. The 'from' and 'to' +parameters are to be given in hexadecimal notation without a leading +0x. +If you supply kernel parameters the different instances are processed +in order of appearance and a minor number is reserved for any device +covered by the supplied range up to 64 volumes. Additional DASDs are +ignored. If you do not supply the 'dasd=' kernel parameter at all, the +DASD driver registers all supported DASDs of your system to a minor +number in ascending order of the subchannel number. + +The driver currently supports ECKD-devices and there are stubs for +support of the FBA and CKD architectures. For the FBA architecture +only some smart data structures are missing to make the support +complete. +We performed our testing on 3380 and 3390 type disks of different +sizes, under VM and on the bare hardware (LPAR), using internal disks +of the multiprise as well as a RAMAC virtual array. Disks exported by +an Enterprise Storage Server (Seascape) should work fine as well. + +We currently implement one partition per volume, which is the whole +volume, skipping the first blocks up to the volume label. These are +reserved for IPL records and IBM's volume label to assure +accessibility of the DASD from other OSs. In a later stage we will +provide support of partitions, maybe VTOC oriented or using a kind of +partition table in the label record. + +Usage +===== + +-Low-level format (?CKD only) +For using an ECKD-DASD as a Linux harddisk you have to low-level +format the tracks by issuing the BLKDASDFORMAT-ioctl on that +device. This will erase any data on that volume including IBM volume +labels, VTOCs etc. The ioctl may take a `struct format_data *` or +'NULL' as an argument:: + + typedef struct { + int start_unit; + int stop_unit; + int blksize; + } format_data_t; + +When a NULL argument is passed to the BLKDASDFORMAT ioctl the whole +disk is formatted to a blocksize of 1024 bytes. Otherwise start_unit +and stop_unit are the first and last track to be formatted. If +stop_unit is -1 it implies that the DASD is formatted from start_unit +up to the last track. blksize can be any power of two between 512 and +4096. We recommend no blksize lower than 1024 because the ext2fs uses +1kB blocks anyway and you gain approx. 50% of capacity increasing your +blksize from 512 byte to 1kB. + +Make a filesystem +================= + +Then you can mk??fs the filesystem of your choice on that volume or +partition. For reasons of sanity you should build your filesystem on +the partition /dev/dd?1 instead of the whole volume.

It usually is fairly consistent & similar from +function to function & if you know its layout you can probably +make some headway in finding the ultimate cause of a problem +after a crash without a source level debugger. + +Note: To follow stackframes requires a knowledge of C or Pascal & +limited knowledge of one assembly language. + +It should be noted that there are some differences between the +s/390 and z/Architecture stack layouts as the z/Architecture stack layout +didn't have to maintain compatibility with older linkage formats. + +Glossary: +--------- +alloca: + This is a built in compiler function for runtime allocation + of extra space on the callers stack which is obviously freed + up on function exit ( e.g. the caller may choose to allocate nothing + of a buffer of 4k if required for temporary purposes ), it generates + very efficient code ( a few cycles ) when compared to alternatives + like malloc. + +automatics: + These are local variables on the stack, i.e they aren't in registers & + they aren't static. + +back-chain: + This is a pointer to the stack pointer before entering a + framed functions ( see frameless function ) prologue got by + dereferencing the address of the current stack pointer, + i.e. got by accessing the 32 bit value at the stack pointers + current location. + +base-pointer: + This is a pointer to the back of the literal pool which + is an area just behind each procedure used to store constants + in each function. + +call-clobbered: + The caller probably needs to save these registers if there + is something of value in them, on the stack or elsewhere before making a + call to another procedure so that it can restore it later. + +epilogue: + The code generated by the compiler to return to the caller. + +frameless-function: + A frameless function in Linux for s390 & z/Architecture is one which doesn't + need more than the register save area (96 bytes on s/390, 160 on z/Architecture) + given to it by the caller. + + A frameless function never: + + 1) Sets up a back chain. + 2) Calls alloca. + 3) Calls other normal functions + 4) Has automatics. + +GOT-pointer: + This is a pointer to the global-offset-table in ELF + ( Executable Linkable Format, Linux'es most common executable format ), + all globals & shared library objects are found using this pointer. + +lazy-binding + ELF shared libraries are typically only loaded when routines in the shared + library are actually first called at runtime.

However, the prologue of this function is somewhat more + hairy owing to it having to move these parameters to the stack to + get va_start, va_arg & va_end to work. +3) Access registers are currently unused by gcc but are used in + the kernel. Possibilities exist to use them at the moment for + temporary storage but it isn't recommended. +4) Only 4 of the floating point registers are used for + parameter passing as older machines such as G3 only have only 4 + & it keeps the stack frame compatible with other compilers. + However with IEEE floating point emulation under linux on the + older machines you are free to use the other 12. +5) A long long or double parameter cannot be have the + first 4 bytes in a register & the second four bytes in the + outgoing args area.

For kernel hacking you will reap dividends if +you get good at it. + +The VM Debugger displays operators but not operands, and also the debugger +displays useful information on the same line as the author of the code probably +felt that it was a good idea not to go over the 80 columns on the screen. +This isn't as unintuitive as it may seem as the s/390 instructions are easy to +decode mentally and you can make a good guess at a lot of them as all the +operands are nibble (half byte aligned). +So if you have an objdump listing by hand, it is quite easy to follow, and if +you don't have an objdump listing keep a copy of the s/390 Reference Summary +or alternatively the s/390 principles of operation next to you. +e.g. even I can guess that +0001AFF8' LR 180F CC 0 +is a ( load register ) lr r0,r15 + +Also it is very easy to tell the length of a 390 instruction from the 2 most +significant bits in the instruction (not that this info is really useful except +if you are trying to make sense of a hexdump of code). +Here is a table + +======================= ================== +Bits Instruction Length +======================= ================== +00 2 Bytes +01 4 Bytes +10 4 Bytes +11 6 Bytes +======================= ================== + +The debugger also displays other useful info on the same line such as the +addresses being operated on destination addresses of branches & condition codes. +e.g.:: + + 00019736' AHI A7DAFF0E CC 1 + 000198BA' BRC A7840004 -> 000198C2' CC 0 + 000198CE' STM 900EF068 >> 0FA95E78 CC 2 + + + +Useful VM debugger commands +--------------------------- + +I suppose I'd better mention this before I start +to list the current active traces do:: + + Q TR + +there can be a maximum of 255 of these per set +( more about trace sets later ). + +To stop traces issue a:: + + TR END. + +To delete a particular breakpoint issue:: + + TR DEL + +The PA1 key drops to CP mode so you can issue debugger commands, +Doing alt c (on my 3270 console at least ) clears the screen. + +hitting b comes back to the running operating system +from cp mode ( in our case linux ). + +It is typically useful to add shortcuts to your profile.exec file +if you have one ( this is roughly equivalent to autoexec.bat in DOS ). +file here are a few from mine:: + + /* this gives me command history on issuing f12 */ + set pf12 retrieve + /* this continues */ + set pf8 imm b + /* goes to trace set a */ + set pf1 imm tr goto a + /* goes to trace set b */ + set pf2 imm tr goto b + /* goes to trace set c */ + set pf3 imm tr goto c + + + +Instruction Tracing +------------------- +Setting a simple breakpoint:: + + TR I PSWA

Instead I'll give a 390 IO architecture +summary for Dummies. If you have the s/390 principles of operation available +read this instead. If nothing else you may find a few useful keywords in here +and be able to use them on a web search engine to find more useful information. + +Unlike other bus architectures modern 390 systems do their IO using mostly +fibre optics and devices such as tapes and disks can be shared between several +mainframes. Also S390 can support up to 65536 devices while a high end PC based +system might be choking with around 64. + +Here is some of the common IO terminology: + +Subchannel: + This is the logical number most IO commands use to talk to an IO device. There + can be up to 0x10000 (65536) of these in a configuration, typically there are a + few hundred. Under VM for simplicity they are allocated contiguously, however + on the native hardware they are not. They typically stay consistent between + boots provided no new hardware is inserted or removed. + + Under Linux for s390 we use these as IRQ's and also when issuing an IO command + (CLEAR SUBCHANNEL, HALT SUBCHANNEL, MODIFY SUBCHANNEL, RESUME SUBCHANNEL, + START SUBCHANNEL, STORE SUBCHANNEL and TEST SUBCHANNEL). We use this as the ID + of the device we wish to talk to. The most important of these instructions are + START SUBCHANNEL (to start IO), TEST SUBCHANNEL (to check whether the IO + completed successfully) and HALT SUBCHANNEL (to kill IO). A subchannel can have + up to 8 channel paths to a device, this offers redundancy if one is not + available. + +Device Number: + This number remains static and is closely tied to the hardware. There are 65536 + of these, made up of a CHPID (Channel Path ID, the most significant 8 bits) and + another lsb 8 bits. These remain static even if more devices are inserted or + removed from the hardware. There is a 1 to 1 mapping between subchannels and + device numbers, provided devices aren't inserted or removed. + +Channel Control Words: + CCWs are linked lists of instructions initially pointed to by an operation + request block (ORB), which is initially given to Start Subchannel (SSCH) + command along with the subchannel number for the IO subsystem to process + while the CPU continues executing normal code. + CCWs come in two flavours, Format 0 (24 bit for backward compatibility) and + Format 1 (31 bit). These are typically used to issue read and write (and many + other) instructions. They consist of a length field and an absolute address + field. + + Each IO typically gets 1 or 2 interrupts, one for channel end (primary status) + when the channel is idle, and the second for device end (secondary status). + Sometimes you get both concurrently. You check how the IO went on by issuing a + TEST SUBCHANNEL at each interrupt, from which you receive an Interruption + response block (IRB). If you get channel and device end status in the IRB + without channel checks etc. your IO probably went okay. If you didn't you + probably need to examine the IRB, extended status word etc. + If an error occurs, more sophisticated control units have a facility known as + concurrent sense. This means that if an error occurs Extended sense information + will be presented in the Extended status word in the IRB. If not you have to + issue a subsequent SENSE CCW command after the test subchannel. + + +TPI (Test pending interrupt) can also be used for polled IO, but in +multitasking multiprocessor systems it isn't recommended except for +checking special cases (i.e. non looping checks for pending IO etc.). + +Store Subchannel and Modify Subchannel can be used to examine and modify +operating characteristics of a subchannel (e.g. channel paths). + +Other IO related Terms: + +Sysplex: + S390's Clustering Technology +QDIO: + S390's new high speed IO architecture to support devices such as gigabit + ethernet, this architecture is also designed to be forward compatible with + upcoming 64 bit machines. + + +General Concepts +---------------- + +Input Output Processors (IOP's) are responsible for communicating between +the mainframe CPU's & the channel & relieve the mainframe CPU's from the +burden of communicating with IO devices directly, this allows the CPU's to +concentrate on data processing. + +IOP's can use one or more links ( known as channel paths ) to talk to each +IO device. It first checks for path availability & chooses an available one, +then starts ( & sometimes terminates IO ). +There are two types of channel path: ESCON & the Parallel IO interface. + +IO devices are attached to control units, control units provide the +logic to interface the channel paths & channel path IO protocols to +the IO devices, they can be integrated with the devices or housed separately +& often talk to several similar devices ( typical examples would be raid +controllers or a control unit which connects to 1000 3270 terminals ):: + + + +---------------------------------------------------------------+ + | +-----+ +-----+ +-----+ +-----+ +----------+ +----------+ | + | | CPU | | CPU | | CPU | | CPU | | Main | | Expanded | | + | | | | | | | | | | Memory | | Storage | | + | +-----+ +-----+ +-----+ +-----+ +----------+ +----------+ | + |---------------------------------------------------------------+ + | IOP | IOP | IOP | + |--------------------------------------------------------------- + | C | C | C | C | C | C | C | C | C | C | C | C | C | C | C | C | + ---------------------------------------------------------------- + || || + || Bus & Tag Channel Path || ESCON + || ====================== || Channel + || || || || Path + +----------+ +----------+ +----------+ + | | | | | | + | CU | | CU | | CU | + | | | | | | + +----------+ +----------+ +----------+ + | | | | | + +----------+ +----------+ +----------+ +----------+ +----------+ + |I/O Device| |I/O Device| |I/O Device| |I/O Device| |I/O Device| + +----------+ +----------+ +----------+ +----------+ +----------+ + CPU = Central Processing Unit + C = Channel + IOP = IP Processor + CU = Control Unit + +The 390 IO systems come in 2 flavours the current 390 machines support both + +The Older 360 & 370 Interface,sometimes called the Parallel I/O interface, +sometimes called Bus-and Tag & sometimes Original Equipment Manufacturers +Interface (OEMI). + +This byte wide Parallel channel path/bus has parity & data on the "Bus" cable +and control lines on the "Tag" cable. These can operate in byte multiplex mode +for sharing between several slow devices or burst mode and monopolize the +channel for the whole burst. Up to 256 devices can be addressed on one of these +cables. These cables are about one inch in diameter. The maximum unextended +length supported by these cables is 125 Meters but this can be extended up to +2km with a fibre optic channel extended such as a 3044. The maximum burst speed +supported is 4.5 megabytes per second. However, some really old processors +support only transfer rates of 3.0, 2.0 & 1.0 MB/sec. +One of these paths can be daisy chained to up to 8 control units. + + +ESCON if fibre optic it is also called FICON +Was introduced by IBM in 1990. Has 2 fibre optic cables and uses either leds or +lasers for communication at a signaling rate of up to 200 megabits/sec. As +10bits are transferred for every 8 bits info this drops to 160 megabits/sec +and to 18.6 Megabytes/sec once control info and CRC are added. ESCON only +operates in burst mode. + +ESCONs typical max cable length is 3km for the led version and 20km for the +laser version known as XDF (extended distance facility). This can be further +extended by using an ESCON director which triples the above mentioned ranges. +Unlike Bus & Tag as ESCON is serial it uses a packet switching architecture, +the standard Bus & Tag control protocol is however present within the packets. +Up to 256 devices can be attached to each control unit that uses one of these +interfaces. + +Common 390 Devices include: +Network adapters typically OSA2,3172's,2116's & OSA-E gigabit ethernet adapters, +Consoles 3270 & 3215 (a teletype emulated under linux for a line mode console). +DASD's direct access storage devices ( otherwise known as hard disks ). +Tape Drives. +CTC ( Channel to Channel Adapters ), +ESCON or Parallel Cables used as a very high speed serial link +between 2 machines. + + +Debugging IO on s/390 & z/Architecture under VM +=============================================== + +Now we are ready to go on with IO tracing commands under VM + +A few self explanatory queries:: + + Q OSA + Q CTC + Q DISK ( This command is CMS specific ) + Q DASD + +Q OSA on my machine returns:: + + OSA 7C08 ON OSA 7C08 SUBCHANNEL = 0000 + OSA 7C09 ON OSA 7C09 SUBCHANNEL = 0001 + OSA 7C14 ON OSA 7C14 SUBCHANNEL = 0002 + OSA 7C15 ON OSA 7C15 SUBCHANNEL = 0003 + +If you have a guest with certain privileges you may be able to see devices +which don't belong to you.

It is usually +called core and created in the current working directory. + +This is very useful in that a customer can mail a core dump to a technical +support department and the technical support department can reconstruct what +happened. Provided they have an identical copy of this program with debugging +symbols compiled in and the source base of this build is available. + +In short it is far more useful than something like a crash log could ever hope +to be. + +Why have I never seen one ? +^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Probably because you haven't used the command:: + + ulimit -c unlimited in bash + +to allow core dumps, now do:: + + ulimit -a + +to verify that the limit was accepted. + +A sample core dump + To create this I'm going to do:: + + ulimit -c unlimited + gdb + +to launch gdb (my victim app. ) now be bad & do the following from another +telnet/xterm session to the same machine:: + + ps -aux | grep gdb + kill -SIGSEGV + +or alternatively use `killall -SIGSEGV gdb` if you have the killall command. + +Now look at the core dump:: + + ./gdb core + +Displays the following:: + + GNU gdb 4.18 + Copyright 1998 Free Software Foundation, Inc. + GDB is free software, covered by the GNU General Public License, and you are + welcome to change it and/or distribute copies of it under certain conditions. + Type "show copying" to see the conditions. + There is absolutely no warranty for GDB.

libraries, however it can be very painful +when you single step instruction into a function like printf for the +first time & you end up in functions like _dl_runtime_resolve this is +the ld.so doing lazy binding, lazy binding is a concept in ELF where +shared library functions are not loaded into memory unless they are +actually used, great for saving memory but a pain to debug. + +To get around this either relink the program -static or exit gdb type +export LD_BIND_NOW=true this will stop lazy binding & restart the gdb'ing +the program in question. + + + +Debugging modules +================= +As modules are dynamically loaded into the kernel their address can be +anywhere to get around this use the -m option with insmod to emit a load +map which can be piped into a file if required. + +The proc file system +==================== +What is it ?. +It is a filesystem created by the kernel with files which are created on demand +by the kernel if read, or can be used to modify kernel parameters, +it is a powerful concept. + +e.g.:: + + cat /proc/sys/net/ipv4/ip_forward + +On my machine outputs:: + + 0 + +telling me ip_forwarding is not on to switch it on I can do:: + + echo 1 > /proc/sys/net/ipv4/ip_forward + +cat it again:: + + cat /proc/sys/net/ipv4/ip_forward + +On my machine now outputs:: + + 1 + +IP forwarding is on. + +There is a lot of useful info in here best found

network drivers +------------------------------------ +ifconfig is a quite useful command +it gives the current state of network drivers. + +If you suspect your network device driver is dead +one way to check is type:: + + ifconfig + +e.g. tr0 + +You should see something like:: + + ifconfig tr0 + tr0 Link encap:16/4 Mbps Token Ring (New) HWaddr 00:04:AC:20:8E:48 + inet addr:9.164.185.132

carrier:0 + collisions:0 txqueuelen:100 + +if the device doesn't say up +try:: + + /etc/rc.d/init.d/network start + +( this starts the network stack & hopefully calls ifconfig tr0 up ). +ifconfig looks at the output of /proc/net/dev and presents it in a more +presentable form. + +Now ping the device from a machine in the same subnet. + +if the RX packets count & TX packets counts don't increment you probably +have problems. + +next:: + + cat /proc/net/arp + +Do you see any hardware addresses in the cache if not you may have problems. +Next try:: + + ping -c 5 + +i.e. the Bcast field above in the output of +ifconfig. Do you see any replies from machines other than the local machine +if not you may have problems. also if the TX packets count in ifconfig +hasn't incremented either you have serious problems in your driver +(e.g. the txbusy field of the network device being stuck on ) +or you may have multiple network devices connected. + + +chandev +------- +There is a new device layer for channel devices, some +drivers e.g. lcs are registered with this layer. + +If the device uses the channel device layer you'll be +able to find what interrupts it uses & the current state +of the device. + +See the manpage chandev.8 &type cat /proc/chandev for more info. + + +SysRq +===== +This is now supported by linux for s/390 & z/Architecture. + +To enable it do compile the kernel with:: + + Kernel Hacking -> Magic SysRq Key Enabled + +Then:: + + echo "1" > /proc/sys/kernel/sysrq + +also type:: + + echo "8" >/proc/sys/kernel/printk + +To make printk output go to console. + +On 390 all commands are prefixed with:: + + ^- + +e.g.:: + + ^-t will show tasks. + ^-? or some unknown command will display help. + +The sysrq key reading is very picky ( I have to type the keys in an +xterm session & paste them into the x3270 console ) +& it may be wise to predefine the keys as described in the VM hints above + +This is particularly useful for syncing disks unmounting & rebooting +if the machine gets partially hung. + +Read Documentation/admin-guide/sysrq.rst for more info + +References: +=========== +- Enterprise Systems Architecture Reference Summary +- Enterprise Systems Architecture Principles of Operation +- Hartmut Penners s390 stack frame sheet. +- IBM Mainframe Channel Attachment a technology brief from a CISCO webpage +- Various bits of man & info pages of Linux. +- Linux & GDB source. +- Various info & man pages. +- CMS Help on tracing commands. +- Linux for s/390 Elf Application Binary Interface +- Linux for z/Series Elf Application Binary Interface ( Both Highly Recommended ) +- z/Architecture Principles of Operation SA22-7832-00 +- Enterprise Systems Architecture/390 Reference Summary SA22-7209-01 & the +- Enterprise Systems Architecture/390 Principles of Operation SA22-7201-05 + +Special Thanks +============== +Special thanks to Neale Ferguson who maintains a much +prettier HTML version of this page at +http://linuxvm.org/penguinvm/ +Bob Grainger Stefan Bader & others for reporting bugs diff --git a/Documentation/s390/driver-model.rst b/Documentation/s390/driver-model.rst new file mode 100644 index 000000000000..ad4bc2dbea43 --- /dev/null +++ b/Documentation/s390/driver-model.rst @@ -0,0 +1,328 @@ +============================= +S/390 driver model interfaces +============================= + +1.

Device 1234 is accessed via subchannel 0 in subchannel set 1. + +The subchannel named 'defunct' does not represent any real subchannel on the +system; it is a pseudo subchannel where disconnected ccw devices are moved to +if they are displaced by another ccw device becoming operational on their +former subchannel. The ccw devices will be moved again to a proper subchannel +if they become operational again on that subchannel. + +You should address a ccw device via its bus id (e.g. 0.0.4711); the device can +be found under bus/ccw/devices/. + +All ccw devices export some data via sysfs. + +cutype: + The control unit type / model. + +devtype: + The device type / model, if applicable. + +availability: + Can be 'good' or 'boxed'; 'no path' or 'no device' for + disconnected devices. + +online: + An interface to set the device online and offline. + In the special case of the device being disconnected (see the + notify function under 1.2), piping 0 to online will forcibly delete + the device. + +The device drivers can add entries to export per-device data and interfaces. + +There is also some data exported on a per-subchannel basis (see under +bus/css/devices/): + +chpids: + Via which chpids the device is connected. + +pimpampom: + The path installed, path available and path operational masks. + +There also might be additional data, for example for block devices. + + +1.1 Bringing up a ccw device +---------------------------- + +This is done in several steps. + +a. Each driver can provide one or more parameter interfaces where parameters can + be specified. These interfaces are also in the driver's responsibility. +b. After a. has been performed, if necessary, the device is finally brought up + via the 'online' interface. + + +1.2 Writing a driver for ccw devices +------------------------------------ + +The basic struct ccw_device and struct ccw_driver data structures can be found +under include/asm/ccwdev.h:: + + struct ccw_device { + spinlock_t *ccwlock; + struct ccw_device_private *private; + struct ccw_device_id id; + + struct ccw_driver *drv; + struct device dev; + int online; + + void (*handler) (struct ccw_device *dev, unsigned long intparm, + struct irb *irb); + }; + + struct ccw_driver { + struct module *owner; + struct ccw_device_id *ids; + int (*probe) (struct ccw_device *); + int (*remove) (struct ccw_device *); + int (*set_online) (struct ccw_device *); + int (*set_offline) (struct ccw_device *); + int (*notify) (struct ccw_device *, int); + struct device_driver driver; + char *name; + }; + +The 'private' field contains data needed for internal i/o operation only, and +is not available to the device driver. + +Each driver should declare in a MODULE_DEVICE_TABLE into which CU types/models +and/or device types/models it is interested. This information can later be found +in the struct ccw_device_id fields:: + + struct ccw_device_id { + __u16 match_flags; + + __u16 cu_type; + __u16 dev_type; + __u8 cu_model; + __u8 dev_model; + + unsigned long driver_info; + }; + +The functions in ccw_driver should be used in the following way: + +probe: + This function is called by the device layer for each device the driver + is interested in. The driver should only allocate private structures + to put in dev->driver_data and create attributes (if needed). Also, + the interrupt handler (see below) should be set here. + +:: + + int (*probe) (struct ccw_device *cdev); + +Parameters: + cdev + - the device to be probed. + + +remove: + This function is called by the device layer upon removal of the driver, + the device or the module. The driver should perform cleanups here. + +:: + + int (*remove) (struct ccw_device *cdev); + +Parameters: + cdev + - the device to be removed. + + +set_online: + This function is called by the common I/O layer when the device is + activated via the 'online' attribute. The driver should finally + setup and activate the device here. + +:: + + int (*set_online) (struct ccw_device *); + +Parameters: + cdev + - the device to be activated. The common layer has + verified that the device is not already online. + + +set_offline: This function is called by the common I/O layer when the device is + de-activated via the 'online' attribute. The driver should shut + down the device, but not de-allocate its private data. + +:: + + int (*set_offline) (struct ccw_device *); + +Parameters: + cdev + - the device to be deactivated. The common layer has + verified that the device is online. + + +notify: + This function is called by the common I/O layer for some state changes + of the device. + + Signalled to the driver are: + + * In online state, device detached (CIO_GONE) or last path gone + (CIO_NO_PATH). The driver must return !0 to keep the device; for + return code 0, the device will be deleted as usual (also when no + notify function is registered). If the driver wants to keep the + device, it is moved into disconnected state. + * In disconnected state, device operational again (CIO_OPER). The + common I/O layer performs some sanity checks on device number and + Device / CU to be reasonably sure if it is still the same device. + If not, the old device is removed and a new one registered. By the + return code of the notify function the device driver signals if it + wants the device back: !0 for keeping, 0 to make the device being + removed and re-registered. + +:: + + int (*notify) (struct ccw_device *, int); + +Parameters: + cdev + - the device whose state changed. + + event + - the event that happened. This can be one of CIO_GONE, + CIO_NO_PATH or CIO_OPER. + +The handler field of the struct ccw_device is meant to be set to the interrupt +handler for the device. In order to accommodate drivers which use several +distinct handlers (e.g. multi subchannel devices), this is a member of ccw_device +instead of ccw_driver. +The handler is registered with the common layer during set_online() processing +before the driver is called, and is deregistered during set_offline() after the +driver has been called. Also, after registering / before deregistering, path +grouping resp. disbanding of the path group (if applicable) are performed. + +:: + + void (*handler) (struct ccw_device *dev, unsigned long intparm, struct irb *irb); + +Parameters: dev - the device the handler is called for + intparm - the intparm which allows the device driver to identify + the i/o the interrupt is associated with, or to recognize + the interrupt as unsolicited. + irb - interruption response block which contains the accumulated + status. + +The device driver is called from the common ccw_device layer and can retrieve +information about the interrupt from the irb parameter. + + +1.3 ccwgroup devices +-------------------- + +The ccwgroup mechanism is designed to handle devices consisting of multiple ccw +devices, like lcs or ctc. + +The ccw driver provides a 'group' attribute. Piping bus ids of ccw devices to +this attributes creates a ccwgroup device consisting of these ccw devices (if +possible). This ccwgroup device can be set online or offline just like a normal +ccw device. + +Each ccwgroup device also provides an 'ungroup' attribute to destroy the device +again (only when offline). This is a generic ccwgroup mechanism (the driver does +not need to implement anything beyond normal removal routines). + +A ccw device which is a member of a ccwgroup device carries a pointer to the +ccwgroup device in the driver_data of its device struct. This field must not be +touched by the driver - it should use the ccwgroup device's driver_data for its +private data. + +To implement a ccwgroup driver, please refer to include/asm/ccwgroup.h. Keep in +mind that most drivers will need to implement both a ccwgroup and a ccw +driver. + + +2. Channel paths +----------------- + +Channel paths show up, like subchannels, under the channel subsystem root (css0) +and are called 'chp0.'. They have no driver and do not belong to any bus. +Please note, that unlike /proc/chpids in 2.4, the channel path objects reflect +only the logical state and not the physical state, since we cannot track the +latter consistently due to lacking machine support (we don't need to be aware +of it anyway). + +status + - Can be 'online' or 'offline'. + Piping 'on' or 'off' sets the chpid logically online/offline. + Piping 'on' to an online chpid triggers path reprobing for all devices + the chpid connects to. This can be used to force the kernel to re-use + a channel path the user knows to be online, but the machine hasn't + created a machine check for. + +type + - The physical type of the channel path. + +shared + - Whether the channel path is shared. + +cmg + - The channel measurement group. + +3.

This information can later be found -in the struct ccw_device_id fields: - -struct ccw_device_id { - __u16 match_flags; - - __u16 cu_type; - __u16 dev_type; - __u8 cu_model; - __u8 dev_model; - - unsigned long driver_info; -}; - -The functions in ccw_driver should be used in the following way: -probe: This function is called by the device layer for each device the driver - is interested in. The driver should only allocate private structures - to put in dev->driver_data and create attributes (if needed). Also, - the interrupt handler (see below) should be set here. - -int (*probe) (struct ccw_device *cdev); - -Parameters: cdev - the device to be probed. - - -remove: This function is called by the device layer upon removal of the driver, - the device or the module. The driver should perform cleanups here. - -int (*remove) (struct ccw_device *cdev); - -Parameters: cdev - the device to be removed. - - -set_online: This function is called by the common I/O layer when the device is - activated via the 'online' attribute. The driver should finally - setup and activate the device here. - -int (*set_online) (struct ccw_device *); - -Parameters: cdev - the device to be activated. The common layer has - verified that the device is not already online. - - -set_offline: This function is called by the common I/O layer when the device is - de-activated via the 'online' attribute. The driver should shut - down the device, but not de-allocate its private data. - -int (*set_offline) (struct ccw_device *); - -Parameters: cdev - the device to be deactivated.

This can be one of CIO_GONE, - CIO_NO_PATH or CIO_OPER. - -The handler field of the struct ccw_device is meant to be set to the interrupt -handler for the device. In order to accommodate drivers which use several -distinct handlers (e.g. multi subchannel devices), this is a member of ccw_device -instead of ccw_driver. -The handler is registered with the common layer during set_online() processing -before the driver is called, and is deregistered during set_offline() after the -driver has been called.

This ccwgroup device can be set online or offline just like a normal -ccw device. - -Each ccwgroup device also provides an 'ungroup' attribute to destroy the device -again (only when offline). This is a generic ccwgroup mechanism (the driver does -not need to implement anything beyond normal removal routines). - -A ccw device which is a member of a ccwgroup device carries a pointer to the -ccwgroup device in the driver_data of its device struct. This field must not be -touched by the driver - it should use the ccwgroup device's driver_data for its -private data. - -To implement a ccwgroup driver, please refer to include/asm/ccwgroup.h. Keep in -mind that most drivers will need to implement both a ccwgroup and a ccw -driver. - - -2. Channel paths ------------------ - -Channel paths show up, like subchannels, under the channel subsystem root (css0) -and are called 'chp0.'. They have no driver and do not belong to any bus. -Please note, that unlike /proc/chpids in 2.4, the channel path objects reflect -only the logical state and not the physical state, since we cannot track the -latter consistently due to lacking machine support (we don't need to be aware -of it anyway). - -status - Can be 'online' or 'offline'. - Piping 'on' or 'off' sets the chpid logically online/offline. - Piping 'on' to an online chpid triggers path reprobing for all devices - the chpid connects to. This can be used to force the kernel to re-use - a channel path the user knows to be online, but the machine hasn't - created a machine check for. - -type - The physical type of the channel path. - -shared - Whether the channel path is shared. - -cmg - The channel measurement group. - -3.

This function initializes a +debug log for the caller. For each debug log exists a number of debug areas +where exactly one is active at one time. Each debug area consists of contiguous +pages in memory. In the debug areas there are stored debug entries (log records) +which are written by event- and exception-calls. + +An event-call writes the specified debug entry to the active debug +area and updates the log pointer for the active area. If the end +of the active debug area is reached, a wrap around is done (ring buffer) +and the next debug entry will be written at the beginning of the active +debug area. + +An exception-call writes the specified debug entry to the log and +switches to the next debug area. This is done in order to be sure +that the records which describe the origin of the exception are not +overwritten when a wrap around for the current area occurs. + +The debug areas themselves are also ordered in form of a ring buffer. +When an exception is thrown in the last debug area, the following debug +entries are then written again in the very first area. + +There are three versions for the event- and exception-calls: One for +logging raw data, one for text and one for numbers. + +Each debug entry contains the following data: + +- Timestamp +- Cpu-Number of calling task +- Level of debug entry (0...6) +- Return Address to caller +- Flag, if entry is an exception or not + +The debug logs can be inspected in a live system through entries in +the debugfs-filesystem. Under the toplevel directory "s390dbf" there is +a directory for each registered component, which is named like the +corresponding component. The debugfs normally should be mounted to +/sys/kernel/debug therefore the debug feature can be accessed under +/sys/kernel/debug/s390dbf. + +The content of the directories are files which represent different views +to the debug log. Each component can decide which views should be +used through registering them with the function debug_register_view(). +Predefined views for hex/ascii, sprintf and raw binary data are provided. +It is also possible to define other views. The content of +a view can be inspected simply by reading the corresponding debugfs file. + +All debug logs have an actual debug level (range from 0 to 6). +The default level is 3. Event and Exception functions have a 'level' +parameter. Only debug entries with a level that is lower or equal +than the actual level are written to the log. This means, when +writing events, high priority log entries should have a low level +value whereas low priority entries should have a high one. +The actual debug level can be changed with the help of the debugfs-filesystem +through writing a number string "x" to the 'level' debugfs file which is +provided for every debug log. Debugging can be switched off completely +by using "-" on the 'level' debugfs file. + +Example:: + + > echo "-" > /sys/kernel/debug/s390dbf/dasd/level + +It is also possible to deactivate the debug feature globally for every +debug log. You can change the behavior using 2 sysctl parameters in +/proc/sys/s390dbf: + +There are currently 2 possible triggers, which stop the debug feature +globally. The first possibility is to use the "debug_active" sysctl. If +set to 1 the debug feature is running. If "debug_active" is set to 0 the +debug feature is turned off. + +The second trigger which stops the debug feature is a kernel oops. +That prevents the debug feature from overwriting debug information that +happened before the oops. After an oops you can reactivate the debug feature +by piping 1 to /proc/sys/s390dbf/debug_active. Nevertheless, its not +suggested to use an oopsed kernel in a production environment. + +If you want to disallow the deactivation of the debug feature, you can use +the "debug_stoppable" sysctl. If you set "debug_stoppable" to 0 the debug +feature cannot be stopped. If the debug feature is already stopped, it +will stay deactivated. + +---------------------------------------------------------------------------- + +Kernel Interfaces: +------------------ + +:: + + debug_info_t *debug_register(char *name, int pages, int nr_areas, + int buf_size); + +Parameter: + name: + Name of debug log (e.g. used for debugfs entry) + pages: + Number of pages, which will be allocated per area + nr_areas: + Number of debug areas + buf_size: + Size of data area in each debug entry + +Return Value: + Handle for generated debug area + + NULL if register failed + +Description: Allocates memory for a debug log + Must not be called within an interrupt handler + +---------------------------------------------------------------------------- + +:: + + debug_info_t *debug_register_mode(char *name, int pages, int nr_areas, + int buf_size, mode_t mode, uid_t uid, + gid_t gid); + +Parameter: + name: + Name of debug log (e.g. used for debugfs entry) + pages: + Number of pages, which will be allocated per area + nr_areas: + Number of debug areas + buf_size: + Size of data area in each debug entry + mode: + File mode for debugfs files.

Stop debug feature:: + + > echo 0 > /proc/sys/s390dbf/debug_active + +lcrash Interface +---------------- +It is planned that the dump analysis tool lcrash gets an additional command +'s390dbf' to display all the debug logs. With this tool it will be possible +to investigate the debug logs on a live system and with a memory dump after +a system crash. + +Investigating raw memory +------------------------ +One last possibility to investigate the debug logs at a live +system and after a system crash is to look at the raw memory +under VM or at the Service Element. +It is possible to find the anker of the debug-logs through +the 'debug_area_first' symbol in the System map. Then one has +to follow the correct pointers of the data-structures defined +in debug.h and find the debug-areas in memory. +Normally modules which use the debug feature will also have +a global variable with the pointer to the debug-logs. Following +this pointer it will also be possible to find the debug logs in +memory. + +For this method it is recommended to use '16 * x + 4' byte (x = 0..n) +for the length of the data field in debug_register() in +order to see the debug entries well formatted. + + +Predefined Views +---------------- + +There are three predefined views: hex_ascii, raw and sprintf. +The hex_ascii view shows the data field in hex and ascii representation +(e.g. '45 43 4b 44 | ECKD'). +The raw view returns a bytestream as the debug areas are stored in memory. + +The sprintf view formats the debug entries in the same way as the sprintf +function would do. The sprintf event/exception functions write to the +debug entry a pointer to the format string (size = sizeof(long)) +and for each vararg a long value. So e.g. for a debug entry with a format +string plus two varargs one would need to allocate a (3 * sizeof(long)) +byte data area in the debug_register() function. + +IMPORTANT: + Using "%s" in sprintf event functions is dangerous. You can only + use "%s" in the sprintf event functions, if the memory for the passed string + is available as long as the debug feature exists.

This function initializes a -debug log for the caller. For each debug log exists a number of debug areas -where exactly one is active at one time. Each debug area consists of contiguous -pages in memory. In the debug areas there are stored debug entries (log records) -which are written by event- and exception-calls. - -An event-call writes the specified debug entry to the active debug -area and updates the log pointer for the active area. If the end -of the active debug area is reached, a wrap around is done (ring buffer) -and the next debug entry will be written at the beginning of the active -debug area. - -An exception-call writes the specified debug entry to the log and -switches to the next debug area. This is done in order to be sure -that the records which describe the origin of the exception are not -overwritten when a wrap around for the current area occurs. - -The debug areas themselves are also ordered in form of a ring buffer. -When an exception is thrown in the last debug area, the following debug -entries are then written again in the very first area. - -There are three versions for the event- and exception-calls: One for -logging raw data, one for text and one for numbers. - -Each debug entry contains the following data: - -- Timestamp -- Cpu-Number of calling task -- Level of debug entry (0...6) -- Return Address to caller -- Flag, if entry is an exception or not - -The debug logs can be inspected in a live system through entries in -the debugfs-filesystem. Under the toplevel directory "s390dbf" there is -a directory for each registered component, which is named like the -corresponding component. The debugfs normally should be mounted to -/sys/kernel/debug therefore the debug feature can be accessed under -/sys/kernel/debug/s390dbf. - -The content of the directories are files which represent different views -to the debug log. Each component can decide which views should be -used through registering them with the function debug_register_view(). -Predefined views for hex/ascii, sprintf and raw binary data are provided. -It is also possible to define other views. The content of -a view can be inspected simply by reading the corresponding debugfs file. - -All debug logs have an actual debug level (range from 0 to 6). -The default level is 3. Event and Exception functions have a 'level' -parameter. Only debug entries with a level that is lower or equal -than the actual level are written to the log. This means, when -writing events, high priority log entries should have a low level -value whereas low priority entries should have a high one. -The actual debug level can be changed with the help of the debugfs-filesystem -through writing a number string "x" to the 'level' debugfs file which is -provided for every debug log. Debugging can be switched off completely -by using "-" on the 'level' debugfs file. - -Example: - -> echo "-" > /sys/kernel/debug/s390dbf/dasd/level - -It is also possible to deactivate the debug feature globally for every -debug log. You can change the behavior using 2 sysctl parameters in -/proc/sys/s390dbf: -There are currently 2 possible triggers, which stop the debug feature -globally. The first possibility is to use the "debug_active" sysctl. If -set to 1 the debug feature is running. If "debug_active" is set to 0 the -debug feature is turned off. -The second trigger which stops the debug feature is a kernel oops. -That prevents the debug feature from overwriting debug information that -happened before the oops. After an oops you can reactivate the debug feature -by piping 1 to /proc/sys/s390dbf/debug_active. Nevertheless, its not -suggested to use an oopsed kernel in a production environment. -If you want to disallow the deactivation of the debug feature, you can use -the "debug_stoppable" sysctl. If you set "debug_stoppable" to 0 the debug -feature cannot be stopped. If the debug feature is already stopped, it -will stay deactivated. - -Kernel Interfaces: ------------------- - ----------------------------------------------------------------------------- -debug_info_t *debug_register(char *name, int pages, int nr_areas, - int buf_size); - -Parameter: name: Name of debug log (e.g. used for debugfs entry) - pages: number of pages, which will be allocated per area - nr_areas: number of debug areas - buf_size: size of data area in each debug entry - -Return Value: Handle for generated debug area - NULL if register failed - -Description: Allocates memory for a debug log - Must not be called within an interrupt handler - ----------------------------------------------------------------------------- -debug_info_t *debug_register_mode(char *name, int pages, int nr_areas, - int buf_size, mode_t mode, uid_t uid, - gid_t gid); - -Parameter: name: Name of debug log (e.g. used for debugfs entry) - pages: Number of pages, which will be allocated per area - nr_areas: Number of debug areas - buf_size: Size of data area in each debug entry - mode: File mode for debugfs files.

Stop debug feature -> echo 0 > /proc/sys/s390dbf/debug_active - -lcrash Interface ----------------- -It is planned that the dump analysis tool lcrash gets an additional command -'s390dbf' to display all the debug logs. With this tool it will be possible -to investigate the debug logs on a live system and with a memory dump after -a system crash. - -Investigating raw memory ------------------------- -One last possibility to investigate the debug logs at a live -system and after a system crash is to look at the raw memory -under VM or at the Service Element. -It is possible to find the anker of the debug-logs through -the 'debug_area_first' symbol in the System map. Then one has -to follow the correct pointers of the data-structures defined -in debug.h and find the debug-areas in memory. -Normally modules which use the debug feature will also have -a global variable with the pointer to the debug-logs. Following -this pointer it will also be possible to find the debug logs in -memory. - -For this method it is recommended to use '16 * x + 4' byte (x = 0..n) -for the length of the data field in debug_register() in -order to see the debug entries well formatted. - - -Predefined Views ----------------- - -There are three predefined views: hex_ascii, raw and sprintf. -The hex_ascii view shows the data field in hex and ascii representation -(e.g. '45 43 4b 44 | ECKD'). -The raw view returns a bytestream as the debug areas are stored in memory. - -The sprintf view formats the debug entries in the same way as the sprintf -function would do. The sprintf event/exception functions write to the -debug entry a pointer to the format string (size = sizeof(long)) -and for each vararg a long value. So e.g. for a debug entry with a format -string plus two varargs one would need to allocate a (3 * sizeof(long)) -byte data area in the debug_register() function. - -IMPORTANT: Using "%s" in sprintf event functions is dangerous. You can only -use "%s" in the sprintf event functions, if the memory for the passed string is -available as long as the debug feature exists.

The motivation for vfio-ap +is to make AP cards available to KVM guests using the VFIO mediated device +framework. This implementation relies considerably on the s390 virtualization +facilities which do most of the hard work of providing direct access to AP +devices. + +AP Architectural Overview +========================= +To facilitate the comprehension of the design, let's start with some +definitions: + +* AP adapter + + An AP adapter is an IBM Z adapter card that can perform cryptographic + functions. There can be from 0 to 256 adapters assigned to an LPAR. Adapters + assigned to the LPAR in which a linux host is running will be available to + the linux host. Each adapter is identified by a number from 0 to 255; however, + the maximum adapter number is determined by machine model and/or adapter type. + When installed, an AP adapter is accessed by AP instructions executed by any + CPU. + + The AP adapter cards are assigned to a given LPAR via the system's Activation + Profile which can be edited via the HMC. When the linux host system is IPL'd + in the LPAR, the AP bus detects the AP adapter cards assigned to the LPAR and + creates a sysfs device for each assigned adapter. For example, if AP adapters + 4 and 10 (0x0a) are assigned to the LPAR, the AP bus will create the following + sysfs device entries:: + + /sys/devices/ap/card04 + /sys/devices/ap/card0a + + Symbolic links to these devices will also be created in the AP bus devices + sub-directory:: + + /sys/bus/ap/devices/[card04] + /sys/bus/ap/devices/[card04] + +* AP domain + + An adapter is partitioned into domains. An adapter can hold up to 256 domains + depending upon the adapter type and hardware configuration. A domain is + identified by a number from 0 to 255; however, the maximum domain number is + determined by machine model and/or adapter type.. A domain can be thought of + as a set of hardware registers and memory used for processing AP commands. A + domain can be configured with a secure private key used for clear key + encryption. A domain is classified in one of two ways depending upon how it + may be accessed: + + * Usage domains are domains that are targeted by an AP instruction to + process an AP command. + + * Control domains are domains that are changed by an AP command sent to a + usage domain; for example, to set the secure private key for the control + domain. + + The AP usage and control domains are assigned to a given LPAR via the system's + Activation Profile which can be edited via the HMC. When a linux host system + is IPL'd in the LPAR, the AP bus module detects the AP usage and control + domains assigned to the LPAR. The domain number of each usage domain and + adapter number of each AP adapter are combined to create AP queue devices + (see AP Queue section below). The domain number of each control domain will be + represented in a bitmask and stored in a sysfs file + /sys/bus/ap/ap_control_domain_mask. The bits in the mask, from most to least + significant bit, correspond to domains 0-255. + +* AP Queue + + An AP queue is the means by which an AP command is sent to a usage domain + inside a specific adapter. An AP queue is identified by a tuple + comprised of an AP adapter ID (APID) and an AP queue index (APQI). The + APQI corresponds to a given usage domain number within the adapter. This tuple + forms an AP Queue Number (APQN) uniquely identifying an AP queue. AP + instructions include a field containing the APQN to identify the AP queue to + which the AP command is to be sent for processing. + + The AP bus will create a sysfs device for each APQN that can be derived from + the cross product of the AP adapter and usage domain numbers detected when the + AP bus module is loaded. For example, if adapters 4 and 10 (0x0a) and usage + domains 6 and 71 (0x47) are assigned to the LPAR, the AP bus will create the + following sysfs entries:: + + /sys/devices/ap/card04/04.0006 + /sys/devices/ap/card04/04.0047 + /sys/devices/ap/card0a/0a.0006 + /sys/devices/ap/card0a/0a.0047 + + The following symbolic links to these devices will be created in the AP bus + devices subdirectory:: + + /sys/bus/ap/devices/[04.0006] + /sys/bus/ap/devices/[04.0047] + /sys/bus/ap/devices/[0a.0006] + /sys/bus/ap/devices/[0a.0047] + +* AP Instructions: + + There are three AP instructions: + + * NQAP: to enqueue an AP command-request message to a queue + * DQAP: to dequeue an AP command-reply message from a queue + * PQAP: to administer the queues + + AP instructions identify the domain that is targeted to process the AP + command; this must be one of the usage domains. An AP command may modify a + domain that is not one of the usage domains, but the modified domain + must be one of the control domains. + +AP and SIE +========== +Let's now take a look at how AP instructions executed on a guest are interpreted +by the hardware. + +A satellite control block called the Crypto Control Block (CRYCB) is attached to +our main hardware virtualization control block. The CRYCB contains three fields +to identify the adapters, usage domains and control domains assigned to the KVM +guest: + +* The AP Mask (APM) field is a bit mask that identifies the AP adapters assigned + to the KVM guest. Each bit in the mask, from left to right (i.e. from most + significant to least significant bit in big endian order), corresponds to + an APID from 0-255. If a bit is set, the corresponding adapter is valid for + use by the KVM guest. + +* The AP Queue Mask (AQM) field is a bit mask identifying the AP usage domains + assigned to the KVM guest. Each bit in the mask, from left to right (i.e. from + most significant to least significant bit in big endian order), corresponds to + an AP queue index (APQI) from 0-255. If a bit is set, the corresponding queue + is valid for use by the KVM guest. + +* The AP Domain Mask field is a bit mask that identifies the AP control domains + assigned to the KVM guest. The ADM bit mask controls which domains can be + changed by an AP command-request message sent to a usage domain from the + guest. Each bit in the mask, from left to right (i.e. from most significant to + least significant bit in big endian order), corresponds to a domain from + 0-255. If a bit is set, the corresponding domain can be modified by an AP + command-request message sent to a usage domain. + +If you recall from the description of an AP Queue, AP instructions include +an APQN to identify the AP queue to which an AP command-request message is to be +sent (NQAP and PQAP instructions), or from which a command-reply message is to +be received (DQAP instruction). The validity of an APQN is defined by the matrix +calculated from the APM and AQM; it is the cross product of all assigned adapter +numbers (APM) with all assigned queue indexes (AQM). For example, if adapters 1 +and 2 and usage domains 5 and 6 are assigned to a guest, the APQNs (1,5), (1,6), +(2,5) and (2,6) will be valid for the guest. + +The APQNs can provide secure key functionality - i.e., a private key is stored +on the adapter card for each of its domains - so each APQN must be assigned to +at most one guest or to the linux host:: + + Example 1: Valid configuration: + ------------------------------ + Guest1: adapters 1,2 domains 5,6 + Guest2: adapter 1,2 domain 7 + + This is valid because both guests have a unique set of APQNs: + Guest1 has APQNs (1,5), (1,6), (2,5), (2,6); + Guest2 has APQNs (1,7), (2,7) + + Example 2: Valid configuration: + ------------------------------ + Guest1: adapters 1,2 domains 5,6 + Guest2: adapters 3,4 domains 5,6 + + This is also valid because both guests have a unique set of APQNs: + Guest1 has APQNs (1,5), (1,6), (2,5), (2,6); + Guest2 has APQNs (3,5), (3,6), (4,5), (4,6) + + Example 3: Invalid configuration: + -------------------------------- + Guest1: adapters 1,2 domains 5,6 + Guest2: adapter 1 domains 6,7 + + This is an invalid configuration because both guests have access to + APQN (1,6). + +The Design +========== +The design introduces three new objects: + +1.

This will serve as the parent device for + all mediated matrix devices used to configure an AP matrix for a guest. +3. The /sys/devices/vfio_ap/matrix device is created by the device core +4. The vfio_ap device driver will register with the AP bus for AP queue devices + of type 10 and higher (CEX4 and newer). The driver will provide the vfio_ap + driver's probe and remove callback interfaces. Devices older than CEX4 queues + are not supported to simplify the implementation by not needlessly + complicating the design by supporting older devices that will go out of + service in the relatively near future, and for which there are few older + systems around on which to test. +5. The AP bus registers the vfio_ap device driver with the device core +6. The administrator edits the AP adapter and queue masks to reserve AP queues + for use by the vfio_ap device driver. +7. The AP bus removes the AP queues reserved for the vfio_ap driver from the + default zcrypt cex4queue driver. +8. The AP bus probes the vfio_ap device driver to bind the queues reserved for + it. +9.

When a device is registered with the VFIO mediated device + framework, the sysfs attribute files identified in the 'mdev_attr_groups' + structure will be created in the mediated matrix device's directory. The + sysfs attributes for a mediated matrix device are: + + assign_adapter / unassign_adapter: + Write-only attributes for assigning/unassigning an AP adapter to/from the + mediated matrix device. To assign/unassign an adapter, the APID of the + adapter is echoed to the respective attribute file. + assign_domain / unassign_domain: + Write-only attributes for assigning/unassigning an AP usage domain to/from + the mediated matrix device. To assign/unassign a domain, the domain + number of the the usage domain is echoed to the respective attribute + file. + matrix: + A read-only file for displaying the APQNs derived from the cross product + of the adapter and domain numbers assigned to the mediated matrix device. + assign_control_domain / unassign_control_domain: + Write-only attributes for assigning/unassigning an AP control domain + to/from the mediated matrix device. To assign/unassign a control domain, + the ID of the domain to be assigned/unassigned is echoed to the respective + attribute file. + control_domains: + A read-only file for displaying the control domain numbers assigned to the + mediated matrix device. + +* functions: + + create: + allocates the ap_matrix_mdev structure used by the vfio_ap driver to: + + * Store the reference to the KVM structure for the guest using the mdev + * Store the AP matrix configuration for the adapters, domains, and control + domains assigned via the corresponding sysfs attributes files + + remove: + deallocates the mediated matrix device's ap_matrix_mdev structure.

The open is invoked when QEMU connects the VFIO iommu group + for the mdev matrix device to the MDEV bus. Access to the KVM structure used + to configure the KVM guest is provided via this callback. The KVM structure, + is used to configure the guest's access to the AP matrix defined via the + mediated matrix device's sysfs attribute files. + release: + unregisters the VFIO_GROUP_NOTIFY_SET_KVM notifier callback function for the + mdev matrix device and deconfigures the guest's AP matrix. + +Configure the APM, AQM and ADM in the CRYCB +------------------------------------------- +Configuring the AP matrix for a KVM guest will be performed when the +VFIO_GROUP_NOTIFY_SET_KVM notifier callback is invoked. The notifier +function is called when QEMU connects to KVM. The guest's AP matrix is +configured via it's CRYCB by: + +* Setting the bits in the APM corresponding to the APIDs assigned to the + mediated matrix device via its 'assign_adapter' interface. +* Setting the bits in the AQM corresponding to the domains assigned to the + mediated matrix device via its 'assign_domain' interface. +* Setting the bits in the ADM corresponding to the domain dIDs assigned to the + mediated matrix device via its 'assign_control_domains' interface. + +The CPU model features for AP +----------------------------- +The AP stack relies on the presence of the AP instructions as well as two +facilities: The AP Facilities Test (APFT) facility; and the AP Query +Configuration Information (QCI) facility. These features/facilities are made +available to a KVM guest via the following CPU model features: + +1. ap: Indicates whether the AP instructions are installed on the guest. This + feature will be enabled by KVM only if the AP instructions are installed + on the host. + +2. apft: Indicates the APFT facility is available on the guest. This facility + can be made available to the guest only if it is available on the host (i.e., + facility bit 15 is set). + +3. apqci: Indicates the AP QCI facility is available on the guest. This facility + can be made available to the guest only if it is available on the host (i.e., + facility bit 12 is set). + +Note: If the user chooses to specify a CPU model different than the 'host' +model to QEMU, the CPU model features and facilities need to be turned on +explicitly; for example:: + + /usr/bin/qemu-system-s390x ... -cpu z13,ap=on,apqci=on,apft=on + +A guest can be precluded from using AP features/facilities by turning them off +explicitly; for example:: + + /usr/bin/qemu-system-s390x ... -cpu host,ap=off,apqci=off,apft=off + +Note: If the APFT facility is turned off (apft=off) for the guest, the guest +will not see any AP devices. The zcrypt device drivers that register for type 10 +and newer AP devices - i.e., the cex4card and cex4queue device drivers - need +the APFT facility to ascertain the facilities installed on a given AP device. If +the APFT facility is not installed on the guest, then the probe of device +drivers will fail since only type 10 and newer devices can be configured for +guest use. + +Example +======= +Let's now provide an example to illustrate how KVM guests may be given +access to AP facilities. For this example, we will show how to configure +three guests such that executing the lszcrypt command on the guests would +look like this: + +Guest1 +------ +=========== ===== ============ +CARD.DOMAIN TYPE MODE +=========== ===== ============ +05 CEX5C CCA-Coproc +05.0004 CEX5C CCA-Coproc +05.00ab CEX5C CCA-Coproc +06 CEX5A Accelerator +06.0004 CEX5A Accelerator +06.00ab CEX5C CCA-Coproc +=========== ===== ============ + +Guest2 +------ +=========== ===== ============ +CARD.DOMAIN TYPE MODE +=========== ===== ============ +05 CEX5A Accelerator +05.0047 CEX5A Accelerator +05.00ff CEX5A Accelerator +=========== ===== ============ + +Guest2 +------ +=========== ===== ============ +CARD.DOMAIN TYPE MODE +=========== ===== ============ +06 CEX5A Accelerator +06.0047 CEX5A Accelerator +06.00ff CEX5A Accelerator +=========== ===== ============ + +These are the steps: + +1.

Secure the AP queues to be used by the three guests so that the host can not + access them. To secure them, there are two sysfs files that specify + bitmasks marking a subset of the APQN range as 'usable by the default AP + queue device drivers' or 'not usable by the default device drivers' and thus + available for use by the vfio_ap device driver'. The location of the sysfs + files containing the masks are:: + + /sys/bus/ap/apmask + /sys/bus/ap/aqmask + + The 'apmask' is a 256-bit mask that identifies a set of AP adapter IDs + (APID). Each bit in the mask, from left to right (i.e., from most significant + to least significant bit in big endian order), corresponds to an APID from + 0-255. If a bit is set, the APID is marked as usable only by the default AP + queue device drivers; otherwise, the APID is usable by the vfio_ap + device driver. + + The 'aqmask' is a 256-bit mask that identifies a set of AP queue indexes + (APQI). Each bit in the mask, from left to right (i.e., from most significant + to least significant bit in big endian order), corresponds to an APQI from + 0-255. If a bit is set, the APQI is marked as usable only by the default AP + queue device drivers; otherwise, the APQI is usable by the vfio_ap device + driver. + + Take, for example, the following mask:: + + 0x7dffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff + + It indicates: + + 1, 2, 3, 4, 5, and 7-255 belong to the default drivers' pool, and 0 and 6 + belong to the vfio_ap device driver's pool. + + The APQN of each AP queue device assigned to the linux host is checked by the + AP bus against the set of APQNs derived from the cross product of APIDs + and APQIs marked as usable only by the default AP queue device drivers.

Each bit + number string must be prepended with a ('+') or minus ('-') to indicate + the corresponding bit is to be switched on ('+') or off ('-'). Some + valid values are: + + - "+0" switches bit 0 on + - "-13" switches bit 13 off + - "+0x41" switches bit 65 on + - "-0xff" switches bit 255 off + + The following example: + + +0,-6,+0x47,-0xf0 + + Switches bits 0 and 71 (0x47) on + + Switches bits 6 and 240 (0xf0) off + + Note that the bits not specified in the list remain as they were before + the operation. + + 2. The masks can also be changed at boot time via parameters on the kernel + command line like this: + + ap.apmask=0xffff ap.aqmask=0x40 + + This would create the following masks:: + + apmask: + 0xffff000000000000000000000000000000000000000000000000000000000000 + + aqmask: + 0x4000000000000000000000000000000000000000000000000000000000000000 + + Resulting in these two pools:: + + default drivers pool: adapter 0-15, domain 1 + alternate drivers pool: adapter 16-255, domains 0, 2-255 + +Securing the APQNs for our example +---------------------------------- + To secure the AP queues 05.0004, 05.0047, 05.00ab, 05.00ff, 06.0004, 06.0047, + 06.00ab, and 06.00ff for use by the vfio_ap device driver, the corresponding + APQNs can either be removed from the default masks:: + + echo -5,-6 > /sys/bus/ap/apmask + + echo -4,-0x47,-0xab,-0xff > /sys/bus/ap/aqmask + + Or the masks can be set as follows:: + + echo 0xf9ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff \ + > apmask + + echo 0xf7fffffffffffffffeffffffffffffffffffffffffeffffffffffffffffffffe \ + > aqmask + + This will result in AP queues 05.0004, 05.0047, 05.00ab, 05.00ff, 06.0004, + 06.0047, 06.00ab, and 06.00ff getting bound to the vfio_ap device driver.

The motivation for vfio-ap -is to make AP cards available to KVM guests using the VFIO mediated device -framework. This implementation relies considerably on the s390 virtualization -facilities which do most of the hard work of providing direct access to AP -devices. - -AP Architectural Overview: -========================= -To facilitate the comprehension of the design, let's start with some -definitions: - -* AP adapter - - An AP adapter is an IBM Z adapter card that can perform cryptographic - functions. There can be from 0 to 256 adapters assigned to an LPAR. Adapters - assigned to the LPAR in which a linux host is running will be available to - the linux host. Each adapter is identified by a number from 0 to 255; however, - the maximum adapter number is determined by machine model and/or adapter type. - When installed, an AP adapter is accessed by AP instructions executed by any - CPU. - - The AP adapter cards are assigned to a given LPAR via the system's Activation - Profile which can be edited via the HMC. When the linux host system is IPL'd - in the LPAR, the AP bus detects the AP adapter cards assigned to the LPAR and - creates a sysfs device for each assigned adapter. For example, if AP adapters - 4 and 10 (0x0a) are assigned to the LPAR, the AP bus will create the following - sysfs device entries: - - /sys/devices/ap/card04 - /sys/devices/ap/card0a - - Symbolic links to these devices will also be created in the AP bus devices - sub-directory: - - /sys/bus/ap/devices/[card04] - /sys/bus/ap/devices/[card04] - -* AP domain - - An adapter is partitioned into domains. An adapter can hold up to 256 domains - depending upon the adapter type and hardware configuration. A domain is - identified by a number from 0 to 255; however, the maximum domain number is - determined by machine model and/or adapter type.. A domain can be thought of - as a set of hardware registers and memory used for processing AP commands. A - domain can be configured with a secure private key used for clear key - encryption. A domain is classified in one of two ways depending upon how it - may be accessed: - - * Usage domains are domains that are targeted by an AP instruction to - process an AP command. - - * Control domains are domains that are changed by an AP command sent to a - usage domain; for example, to set the secure private key for the control - domain. - - The AP usage and control domains are assigned to a given LPAR via the system's - Activation Profile which can be edited via the HMC. When a linux host system - is IPL'd in the LPAR, the AP bus module detects the AP usage and control - domains assigned to the LPAR. The domain number of each usage domain and - adapter number of each AP adapter are combined to create AP queue devices - (see AP Queue section below). The domain number of each control domain will be - represented in a bitmask and stored in a sysfs file - /sys/bus/ap/ap_control_domain_mask. The bits in the mask, from most to least - significant bit, correspond to domains 0-255. - -* AP Queue - - An AP queue is the means by which an AP command is sent to a usage domain - inside a specific adapter. An AP queue is identified by a tuple - comprised of an AP adapter ID (APID) and an AP queue index (APQI). The - APQI corresponds to a given usage domain number within the adapter. This tuple - forms an AP Queue Number (APQN) uniquely identifying an AP queue. AP - instructions include a field containing the APQN to identify the AP queue to - which the AP command is to be sent for processing. - - The AP bus will create a sysfs device for each APQN that can be derived from - the cross product of the AP adapter and usage domain numbers detected when the - AP bus module is loaded. For example, if adapters 4 and 10 (0x0a) and usage - domains 6 and 71 (0x47) are assigned to the LPAR, the AP bus will create the - following sysfs entries: - - /sys/devices/ap/card04/04.0006 - /sys/devices/ap/card04/04.0047 - /sys/devices/ap/card0a/0a.0006 - /sys/devices/ap/card0a/0a.0047 - - The following symbolic links to these devices will be created in the AP bus - devices subdirectory: - - /sys/bus/ap/devices/[04.0006] - /sys/bus/ap/devices/[04.0047] - /sys/bus/ap/devices/[0a.0006] - /sys/bus/ap/devices/[0a.0047] - -* AP Instructions: - - There are three AP instructions: - - * NQAP: to enqueue an AP command-request message to a queue - * DQAP: to dequeue an AP command-reply message from a queue - * PQAP: to administer the queues - - AP instructions identify the domain that is targeted to process the AP - command; this must be one of the usage domains. An AP command may modify a - domain that is not one of the usage domains, but the modified domain - must be one of the control domains. - -AP and SIE: -========== -Let's now take a look at how AP instructions executed on a guest are interpreted -by the hardware. - -A satellite control block called the Crypto Control Block (CRYCB) is attached to -our main hardware virtualization control block. The CRYCB contains three fields -to identify the adapters, usage domains and control domains assigned to the KVM -guest: - -* The AP Mask (APM) field is a bit mask that identifies the AP adapters assigned - to the KVM guest. Each bit in the mask, from left to right (i.e. from most - significant to least significant bit in big endian order), corresponds to - an APID from 0-255. If a bit is set, the corresponding adapter is valid for - use by the KVM guest. - -* The AP Queue Mask (AQM) field is a bit mask identifying the AP usage domains - assigned to the KVM guest. Each bit in the mask, from left to right (i.e. from - most significant to least significant bit in big endian order), corresponds to - an AP queue index (APQI) from 0-255. If a bit is set, the corresponding queue - is valid for use by the KVM guest. - -* The AP Domain Mask field is a bit mask that identifies the AP control domains - assigned to the KVM guest. The ADM bit mask controls which domains can be - changed by an AP command-request message sent to a usage domain from the - guest. Each bit in the mask, from left to right (i.e. from most significant to - least significant bit in big endian order), corresponds to a domain from - 0-255. If a bit is set, the corresponding domain can be modified by an AP - command-request message sent to a usage domain. - -If you recall from the description of an AP Queue, AP instructions include -an APQN to identify the AP queue to which an AP command-request message is to be -sent (NQAP and PQAP instructions), or from which a command-reply message is to -be received (DQAP instruction). The validity of an APQN is defined by the matrix -calculated from the APM and AQM; it is the cross product of all assigned adapter -numbers (APM) with all assigned queue indexes (AQM). For example, if adapters 1 -and 2 and usage domains 5 and 6 are assigned to a guest, the APQNs (1,5), (1,6), -(2,5) and (2,6) will be valid for the guest. - -The APQNs can provide secure key functionality - i.e., a private key is stored -on the adapter card for each of its domains - so each APQN must be assigned to -at most one guest or to the linux host. - - Example 1: Valid configuration: - ------------------------------ - Guest1: adapters 1,2 domains 5,6 - Guest2: adapter 1,2 domain 7 - - This is valid because both guests have a unique set of APQNs: - Guest1 has APQNs (1,5), (1,6), (2,5), (2,6); - Guest2 has APQNs (1,7), (2,7) - - Example 2: Valid configuration: - ------------------------------ - Guest1: adapters 1,2 domains 5,6 - Guest2: adapters 3,4 domains 5,6 - - This is also valid because both guests have a unique set of APQNs: - Guest1 has APQNs (1,5), (1,6), (2,5), (2,6); - Guest2 has APQNs (3,5), (3,6), (4,5), (4,6) - - Example 3: Invalid configuration: - -------------------------------- - Guest1: adapters 1,2 domains 5,6 - Guest2: adapter 1 domains 6,7 - - This is an invalid configuration because both guests have access to - APQN (1,6). - -The Design: -=========== -The design introduces three new objects: - -1.

This - feature will be enabled by KVM only if the AP instructions are installed - on the host. - -2. apft: Indicates the APFT facility is available on the guest. This facility - can be made available to the guest only if it is available on the host (i.e., - facility bit 15 is set). - -3. apqci: Indicates the AP QCI facility is available on the guest. This facility - can be made available to the guest only if it is available on the host (i.e., - facility bit 12 is set). - -Note: If the user chooses to specify a CPU model different than the 'host' -model to QEMU, the CPU model features and facilities need to be turned on -explicitly; for example: - - /usr/bin/qemu-system-s390x ... -cpu z13,ap=on,apqci=on,apft=on - -A guest can be precluded from using AP features/facilities by turning them off -explicitly; for example: - - /usr/bin/qemu-system-s390x ... -cpu host,ap=off,apqci=off,apft=off - -Note: If the APFT facility is turned off (apft=off) for the guest, the guest -will not see any AP devices. The zcrypt device drivers that register for type 10 -and newer AP devices - i.e., the cex4card and cex4queue device drivers - need -the APFT facility to ascertain the facilities installed on a given AP device. If -the APFT facility is not installed on the guest, then the probe of device -drivers will fail since only type 10 and newer devices can be configured for -guest use. - -Example: -======= -Let's now provide an example to illustrate how KVM guests may be given -access to AP facilities. For this example, we will show how to configure -three guests such that executing the lszcrypt command on the guests would -look like this: - -Guest1 ------- -CARD.DOMAIN TYPE MODE ------------------------------- -05 CEX5C CCA-Coproc -05.0004 CEX5C CCA-Coproc -05.00ab CEX5C CCA-Coproc -06 CEX5A Accelerator -06.0004 CEX5A Accelerator -06.00ab CEX5C CCA-Coproc - -Guest2 ------- -CARD.DOMAIN TYPE MODE ------------------------------- -05 CEX5A Accelerator -05.0047 CEX5A Accelerator -05.00ff CEX5A Accelerator - -Guest2 ------- -CARD.DOMAIN TYPE MODE ------------------------------- -06 CEX5A Accelerator -06.0047 CEX5A Accelerator -06.00ff CEX5A Accelerator - -These are the steps: - -1. Install the vfio_ap module on the linux host. The dependency chain for the - vfio_ap module is: - * iommu - * s390 - * zcrypt - * vfio - * vfio_mdev - * vfio_mdev_device - * KVM - - To build the vfio_ap module, the kernel build must be configured with the - following Kconfig elements selected: - * IOMMU_SUPPORT - * S390 - * ZCRYPT - * S390_AP_IOMMU - * VFIO - * VFIO_MDEV - * VFIO_MDEV_DEVICE - * KVM - - If using make menuconfig select the following to build the vfio_ap module: - -> Device Drivers - -> IOMMU Hardware Support - select S390 AP IOMMU Support - -> VFIO Non-Privileged userspace driver framework - -> Mediated device driver frramework - -> VFIO driver for Mediated devices - -> I/O subsystem - -> VFIO support for AP devices - -2. Secure the AP queues to be used by the three guests so that the host can not - access them. To secure them, there are two sysfs files that specify - bitmasks marking a subset of the APQN range as 'usable by the default AP - queue device drivers' or 'not usable by the default device drivers' and thus - available for use by the vfio_ap device driver'. The location of the sysfs - files containing the masks are: - - /sys/bus/ap/apmask - /sys/bus/ap/aqmask - - The 'apmask' is a 256-bit mask that identifies a set of AP adapter IDs - (APID). Each bit in the mask, from left to right (i.e., from most significant - to least significant bit in big endian order), corresponds to an APID from - 0-255. If a bit is set, the APID is marked as usable only by the default AP - queue device drivers; otherwise, the APID is usable by the vfio_ap - device driver. - - The 'aqmask' is a 256-bit mask that identifies a set of AP queue indexes - (APQI). Each bit in the mask, from left to right (i.e., from most significant - to least significant bit in big endian order), corresponds to an APQI from - 0-255. If a bit is set, the APQI is marked as usable only by the default AP - queue device drivers; otherwise, the APQI is usable by the vfio_ap device - driver. - - Take, for example, the following mask: - - 0x7dffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff - - It indicates: - - 1, 2, 3, 4, 5, and 7-255 belong to the default drivers' pool, and 0 and 6 - belong to the vfio_ap device driver's pool. - - The APQN of each AP queue device assigned to the linux host is checked by the - AP bus against the set of APQNs derived from the cross product of APIDs - and APQIs marked as usable only by the default AP queue device drivers. If a - match is detected, only the default AP queue device drivers will be probed; - otherwise, the vfio_ap device driver will be probed. - - By default, the two masks are set to reserve all APQNs for use by the default - AP queue device drivers. There are two ways the default masks can be changed: - - 1. The sysfs mask files can be edited by echoing a string into the - respective sysfs mask file in one of two formats: - - * An absolute hex string starting with 0x - like "0x12345678" - sets - the mask. If the given string is shorter than the mask, it is padded - with 0s on the right; for example, specifying a mask value of 0x41 is - the same as specifying: - - 0x4100000000000000000000000000000000000000000000000000000000000000 - - Keep in mind that the mask reads from left to right (i.e., most - significant to least significant bit in big endian order), so the mask - above identifies device numbers 1 and 7 (01000001). - - If the string is longer than the mask, the operation is terminated with - an error (EINVAL). - - * Individual bits in the mask can be switched on and off by specifying - each bit number to be switched in a comma separated list. Each bit - number string must be prepended with a ('+') or minus ('-') to indicate - the corresponding bit is to be switched on ('+') or off ('-'). Some - valid values are: - - "+0" switches bit 0 on - "-13" switches bit 13 off - "+0x41" switches bit 65 on - "-0xff" switches bit 255 off - - The following example: - +0,-6,+0x47,-0xf0 - - Switches bits 0 and 71 (0x47) on - Switches bits 6 and 240 (0xf0) off - - Note that the bits not specified in the list remain as they were before - the operation. - - 2. The masks can also be changed at boot time via parameters on the kernel - command line like this: - - ap.apmask=0xffff ap.aqmask=0x40 - - This would create the following masks: - - apmask: - 0xffff000000000000000000000000000000000000000000000000000000000000 - - aqmask: - 0x4000000000000000000000000000000000000000000000000000000000000000 - - Resulting in these two pools: - - default drivers pool: adapter 0-15, domain 1 - alternate drivers pool: adapter 16-255, domains 0, 2-255 - - Securing the APQNs for our example: - ---------------------------------- - To secure the AP queues 05.0004, 05.0047, 05.00ab, 05.00ff, 06.0004, 06.0047, - 06.00ab, and 06.00ff for use by the vfio_ap device driver, the corresponding - APQNs can either be removed from the default masks: - - echo -5,-6 > /sys/bus/ap/apmask - - echo -4,-0x47,-0xab,-0xff > /sys/bus/ap/aqmask - - Or the masks can be set as follows: - - echo 0xf9ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff \ - > apmask - - echo 0xf7fffffffffffffffeffffffffffffffffffffffffeffffffffffffffffffffe \ - > aqmask - - This will result in AP queues 05.0004, 05.0047, 05.00ab, 05.00ff, 06.0004, - 06.0047, 06.00ab, and 06.00ff getting bound to the vfio_ap device driver. The - sysfs directory for the vfio_ap device driver will now contain symbolic links - to the AP queue devices bound to it: - - /sys/bus/ap - ... [drivers] - ...... [vfio_ap] - ......... [05.0004] - ......... [05.0047] - ......... [05.00ab] - ......... [05.00ff] - ......... [06.0004] - ......... [06.0047] - ......... [06.00ab] - ......... [06.00ff] - - Keep in mind that only type 10 and newer adapters (i.e., CEX4 and later) - can be bound to the vfio_ap device driver. The reason for this is to - simplify the implementation by not needlessly complicating the design by - supporting older devices that will go out of service in the relatively near - future and for which there are few older systems on which to test. - - The administrator, therefore, must take care to secure only AP queues that - can be bound to the vfio_ap device driver. The device type for a given AP - queue device can be read from the parent card's sysfs directory. For example, - to see the hardware type of the queue 05.0004: - - cat /sys/bus/ap/devices/card05/hwtype - - The hwtype must be 10 or higher (CEX4 or newer) in order to be bound to the - vfio_ap device driver. - -3. Create the mediated devices needed to configure the AP matrixes for the - three guests and to provide an interface to the vfio_ap driver for - use by the guests: - - /sys/devices/vfio_ap/matrix/ - --- [mdev_supported_types] - ------ [vfio_ap-passthrough] (passthrough mediated matrix device type) - --------- create - --------- [devices] - - To create the mediated devices for the three guests: - - uuidgen > create - uuidgen > create - uuidgen > create - - or - - echo $uuid1 > create - echo $uuid2 > create - echo $uuid3 > create - - This will create three mediated devices in the [devices] subdirectory named - after the UUID written to the create attribute file.

If an adapter number - higher than the maximum is specified, the operation will terminate with - an error (ENODEV). - - * All APQNs that can be derived from the adapter ID and the IDs of - the previously assigned domains must be bound to the vfio_ap device - driver. If no domains have yet been assigned, then there must be at least - one APQN with the specified APID bound to the vfio_ap driver. If no such - APQNs are bound to the driver, the operation will terminate with an - error (EADDRNOTAVAIL). - - No APQN that can be derived from the adapter ID and the IDs of the - previously assigned domains can be assigned to another mediated matrix - device.

Motivation for vfio-ccw is to passthrough subchannels to a +virtual machine, while vfio is the means. + +Different than other hardware architectures, s390 has defined a unified +I/O access method, which is so called Channel I/O. It has its own access +patterns: + +- Channel programs run asynchronously on a separate (co)processor. +- The channel subsystem will access any memory designated by the caller + in the channel program directly, i.e. there is no iommu involved. + +Thus when we introduce vfio support for these devices, we realize it +with a mediated device (mdev) implementation. The vfio mdev will be +added to an iommu group, so as to make itself able to be managed by the +vfio framework. And we add read/write callbacks for special vfio I/O +regions to pass the channel programs from the mdev to its parent device +(the real I/O subchannel device) to do further address translation and +to perform I/O instructions. + +This document does not intend to explain the s390 I/O architecture in +every detail. More information/reference could be found here: + +- A good start to know Channel I/O in general: + https://en.wikipedia.org/wiki/Channel_I/O +- s390 architecture: + s390 Principles of Operation manual (IBM Form. No. SA22-7832) +- The existing QEMU code which implements a simple emulated channel + subsystem could also be a good reference. It makes it easier to follow + the flow. + qemu/hw/s390x/css.c + +For vfio mediated device framework: +- Documentation/vfio-mediated-device.txt + +Motivation of vfio-ccw +---------------------- + +Typically, a guest virtualized via QEMU/KVM on s390 only sees +paravirtualized virtio devices via the "Virtio Over Channel I/O +(virtio-ccw)" transport. This makes virtio devices discoverable via +standard operating system algorithms for handling channel devices. + +However this is not enough. On s390 for the majority of devices, which +use the standard Channel I/O based mechanism, we also need to provide +the functionality of passing through them to a QEMU virtual machine. +This includes devices that don't have a virtio counterpart (e.g. tape +drives) or that have specific characteristics which guests want to +exploit. + +For passing a device to a guest, we want to use the same interface as +everybody else, namely vfio. We implement this vfio support for channel +devices via the vfio mediated device framework and the subchannel device +driver "vfio_ccw". + +Access patterns of CCW devices +------------------------------ + +s390 architecture has implemented a so called channel subsystem, that +provides a unified view of the devices physically attached to the +systems. Though the s390 hardware platform knows about a huge variety of +different peripheral attachments like disk devices (aka. DASDs), tapes, +communication controllers, etc. They can all be accessed by a well +defined access method and they are presenting I/O completion a unified +way: I/O interruptions. + +All I/O requires the use of channel command words (CCWs). A CCW is an +instruction to a specialized I/O channel processor. A channel program is +a sequence of CCWs which are executed by the I/O channel subsystem. To +issue a channel program to the channel subsystem, it is required to +build an operation request block (ORB), which can be used to point out +the format of the CCW and other control information to the system. The +operating system signals the I/O channel subsystem to begin executing +the channel program with a SSCH (start sub-channel) instruction. The +central processor is then free to proceed with non-I/O instructions +until interrupted. The I/O completion result is received by the +interrupt handler in the form of interrupt response block (IRB). + +Back to vfio-ccw, in short: + +- ORBs and channel programs are built in guest kernel (with guest + physical addresses). +- ORBs and channel programs are passed to the host kernel. +- Host kernel translates the guest physical addresses to real addresses + and starts the I/O with issuing a privileged Channel I/O instruction + (e.g SSCH). +- channel programs run asynchronously on a separate processor. +- I/O completion will be signaled to the host with I/O interruptions. + And it will be copied as IRB to user space to pass it back to the + guest. + +Physical vfio ccw device and its child mdev +------------------------------------------- + +As mentioned above, we realize vfio-ccw with a mdev implementation. + +Channel I/O does not have IOMMU hardware support, so the physical +vfio-ccw device does not have an IOMMU level translation or isolation. + +Subchannel I/O instructions are all privileged instructions. When +handling the I/O instruction interception, vfio-ccw has the software +policing and translation how the channel program is programmed before +it gets sent to hardware. + +Within this implementation, we have two drivers for two types of +devices: + +- The vfio_ccw driver for the physical subchannel device. + This is an I/O subchannel driver for the real subchannel device. It + realizes a group of callbacks and registers to the mdev framework as a + parent (physical) device. As a consequence, mdev provides vfio_ccw a + generic interface (sysfs) to create mdev devices. A vfio mdev could be + created by vfio_ccw then and added to the mediated bus. It is the vfio + device that added to an IOMMU group and a vfio group. + vfio_ccw also provides an I/O region to accept channel program + request from user space and store I/O interrupt result for user + space to retrieve. To notify user space an I/O completion, it offers + an interface to setup an eventfd fd for asynchronous signaling. + +- The vfio_mdev driver for the mediated vfio ccw device. + This is provided by the mdev framework. It is a vfio device driver for + the mdev that created by vfio_ccw. + It realizes a group of vfio device driver callbacks, adds itself to a + vfio group, and registers itself to the mdev framework as a mdev + driver. + It uses a vfio iommu backend that uses the existing map and unmap + ioctls, but rather than programming them into an IOMMU for a device, + it simply stores the translations for use by later requests. This + means that a device programmed in a VM with guest physical addresses + can have the vfio kernel convert that address to process virtual + address, pin the page and program the hardware with the host physical + address in one step. + For a mdev, the vfio iommu backend will not pin the pages during the + VFIO_IOMMU_MAP_DMA ioctl. Mdev framework will only maintain a database + of the iova<->vaddr mappings in this operation. And they export a + vfio_pin_pages and a vfio_unpin_pages interfaces from the vfio iommu + backend for the physical devices to pin and unpin pages by demand. + +Below is a high Level block diagram:: + + +-------------+ + | | + | +---------+ | mdev_register_driver() +--------------+ + | | Mdev | +<-----------------------+ | + | | bus | | | vfio_mdev.ko | + | | driver | +----------------------->+ |<-> VFIO user + | +---------+ | probe()/remove() +--------------+ APIs + | | + | MDEV CORE | + | MODULE | + | mdev.ko | + | +---------+ | mdev_register_device() +--------------+ + | |Physical | +<-----------------------+ | + | | device | | | vfio_ccw.ko |<-> subchannel + | |interface| +----------------------->+ | device + | +---------+ | callback +--------------+ + +-------------+ + +The process of how these work together. + +1. vfio_ccw.ko drives the physical I/O subchannel, and registers the + physical device (with callbacks) to mdev framework. + When vfio_ccw probing the subchannel device, it registers device + pointer and callbacks to the mdev framework. Mdev related file nodes + under the device node in sysfs would be created for the subchannel + device, namely 'mdev_create', 'mdev_destroy' and + 'mdev_supported_types'. +2. Create a mediated vfio ccw device. + Use the 'mdev_create' sysfs file, we need to manually create one (and + only one for our case) mediated device. +3. vfio_mdev.ko drives the mediated ccw device. + vfio_mdev is also the vfio device drvier. It will probe the mdev and + add it to an iommu_group and a vfio_group. Then we could pass through + the mdev to a guest. + +vfio-ccw I/O region +------------------- + +An I/O region is used to accept channel program request from user +space and store I/O interrupt result for user space to retrieve. The +definition of the region is:: + + struct ccw_io_region { + #define ORB_AREA_SIZE 12 + __u8 orb_area[ORB_AREA_SIZE]; + #define SCSW_AREA_SIZE 12 + __u8 scsw_area[SCSW_AREA_SIZE]; + #define IRB_AREA_SIZE 96 + __u8 irb_area[IRB_AREA_SIZE]; + __u32 ret_code; + } __packed; + +While starting an I/O request, orb_area should be filled with the +guest ORB, and scsw_area should be filled with the SCSW of the Virtual +Subchannel. + +irb_area stores the I/O result. + +ret_code stores a return code for each access of the region. + +vfio-ccw operation details +-------------------------- + +vfio-ccw follows what vfio-pci did on the s390 platform and uses +vfio-iommu-type1 as the vfio iommu backend. + +* CCW translation APIs + A group of APIs (start with `cp_`) to do CCW translation. The CCWs + passed in by a user space program are organized with their guest + physical memory addresses. These APIs will copy the CCWs into kernel + space, and assemble a runnable kernel channel program by updating the + guest physical addresses with their corresponding host physical addresses. + Note that we have to use IDALs even for direct-access CCWs, as the + referenced memory can be located anywhere, including above 2G. + +* vfio_ccw device driver + This driver utilizes the CCW translation APIs and introduces + vfio_ccw, which is the driver for the I/O subchannel devices you want + to pass through. + vfio_ccw implements the following vfio ioctls:: + + VFIO_DEVICE_GET_INFO + VFIO_DEVICE_GET_IRQ_INFO + VFIO_DEVICE_GET_REGION_INFO + VFIO_DEVICE_RESET + VFIO_DEVICE_SET_IRQS + + This provides an I/O region, so that the user space program can pass a + channel program to the kernel, to do further CCW translation before + issuing them to a real device. + This also provides the SET_IRQ ioctl to setup an event notifier to + notify the user space program the I/O completion in an asynchronous + way. + +The use of vfio-ccw is not limited to QEMU, while QEMU is definitely a +good example to get understand how these patches work. Here is a little +bit more detail how an I/O request triggered by the QEMU guest will be +handled (without error handling). + +Explanation: + +- Q1-Q7: QEMU side process. +- K1-K5: Kernel side process. + +Q1. + Get I/O region info during initialization. + +Q2. + Setup event notifier and handler to handle I/O completion. + +... ... + +Q3. + Intercept a ssch instruction. +Q4. + Write the guest channel program and ORB to the I/O region. + + K1. + Copy from guest to kernel. + K2. + Translate the guest channel program to a host kernel space + channel program, which becomes runnable for a real device. + K3. + With the necessary information contained in the orb passed in + by QEMU, issue the ccwchain to the device. + K4. + Return the ssch CC code. +Q5. + Return the CC code to the guest. + +... ... + + K5. + Interrupt handler gets the I/O result and write the result to + the I/O region. + K6. + Signal QEMU to retrieve the result. + +Q6. + Get the signal and event handler reads out the result from the I/O + region. +Q7. + Update the irb for the guest. + +Limitations +----------- + +The current vfio-ccw implementation focuses on supporting basic commands +needed to implement block device functionality (read/write) of DASD/ECKD +device only. Some commands may need special handling in the future, for +example, anything related to path grouping. + +DASD is a kind of storage device. While ECKD is a data recording format. +More information for DASD and ECKD could be found here: +https://en.wikipedia.org/wiki/Direct-access_storage_device +https://en.wikipedia.org/wiki/Count_key_data + +Together with the corresponding work in QEMU, we can bring the passed +through DASD/ECKD device online in a guest now and use it as a block +device. + +While the current code allows the guest to start channel programs via +START SUBCHANNEL, support for HALT SUBCHANNEL or CLEAR SUBCHANNEL is +not yet implemented. + +vfio-ccw supports classic (command mode) channel I/O only.

Motivation for vfio-ccw is to passthrough subchannels to a -virtual machine, while vfio is the means. - -Different than other hardware architectures, s390 has defined a unified -I/O access method, which is so called Channel I/O. It has its own access -patterns: -- Channel programs run asynchronously on a separate (co)processor. -- The channel subsystem will access any memory designated by the caller - in the channel program directly, i.e. there is no iommu involved. -Thus when we introduce vfio support for these devices, we realize it -with a mediated device (mdev) implementation. The vfio mdev will be -added to an iommu group, so as to make itself able to be managed by the -vfio framework. And we add read/write callbacks for special vfio I/O -regions to pass the channel programs from the mdev to its parent device -(the real I/O subchannel device) to do further address translation and -to perform I/O instructions. - -This document does not intend to explain the s390 I/O architecture in -every detail. More information/reference could be found here: -- A good start to know Channel I/O in general: - https://en.wikipedia.org/wiki/Channel_I/O -- s390 architecture: - s390 Principles of Operation manual (IBM Form. No. SA22-7832) -- The existing QEMU code which implements a simple emulated channel - subsystem could also be a good reference. It makes it easier to follow - the flow. - qemu/hw/s390x/css.c - -For vfio mediated device framework: -- Documentation/vfio-mediated-device.txt - -Motivation of vfio-ccw ----------------------- - -Typically, a guest virtualized via QEMU/KVM on s390 only sees -paravirtualized virtio devices via the "Virtio Over Channel I/O -(virtio-ccw)" transport. This makes virtio devices discoverable via -standard operating system algorithms for handling channel devices. - -However this is not enough. On s390 for the majority of devices, which -use the standard Channel I/O based mechanism, we also need to provide -the functionality of passing through them to a QEMU virtual machine. -This includes devices that don't have a virtio counterpart (e.g. tape -drives) or that have specific characteristics which guests want to -exploit. - -For passing a device to a guest, we want to use the same interface as -everybody else, namely vfio. We implement this vfio support for channel -devices via the vfio mediated device framework and the subchannel device -driver "vfio_ccw". - -Access patterns of CCW devices ------------------------------- - -s390 architecture has implemented a so called channel subsystem, that -provides a unified view of the devices physically attached to the -systems. Though the s390 hardware platform knows about a huge variety of -different peripheral attachments like disk devices (aka. DASDs), tapes, -communication controllers, etc. They can all be accessed by a well -defined access method and they are presenting I/O completion a unified -way: I/O interruptions. - -All I/O requires the use of channel command words (CCWs). A CCW is an -instruction to a specialized I/O channel processor. A channel program is -a sequence of CCWs which are executed by the I/O channel subsystem. To -issue a channel program to the channel subsystem, it is required to -build an operation request block (ORB), which can be used to point out -the format of the CCW and other control information to the system. The -operating system signals the I/O channel subsystem to begin executing -the channel program with a SSCH (start sub-channel) instruction. The -central processor is then free to proceed with non-I/O instructions -until interrupted. The I/O completion result is received by the -interrupt handler in the form of interrupt response block (IRB). - -Back to vfio-ccw, in short: -- ORBs and channel programs are built in guest kernel (with guest - physical addresses). -- ORBs and channel programs are passed to the host kernel. -- Host kernel translates the guest physical addresses to real addresses - and starts the I/O with issuing a privileged Channel I/O instruction - (e.g SSCH). -- channel programs run asynchronously on a separate processor. -- I/O completion will be signaled to the host with I/O interruptions. - And it will be copied as IRB to user space to pass it back to the - guest. - -Physical vfio ccw device and its child mdev -------------------------------------------- - -As mentioned above, we realize vfio-ccw with a mdev implementation. - -Channel I/O does not have IOMMU hardware support, so the physical -vfio-ccw device does not have an IOMMU level translation or isolation. - -Subchannel I/O instructions are all privileged instructions. When -handling the I/O instruction interception, vfio-ccw has the software -policing and translation how the channel program is programmed before -it gets sent to hardware. - -Within this implementation, we have two drivers for two types of -devices: -- The vfio_ccw driver for the physical subchannel device. - This is an I/O subchannel driver for the real subchannel device. It - realizes a group of callbacks and registers to the mdev framework as a - parent (physical) device. As a consequence, mdev provides vfio_ccw a - generic interface (sysfs) to create mdev devices. A vfio mdev could be - created by vfio_ccw then and added to the mediated bus. It is the vfio - device that added to an IOMMU group and a vfio group. - vfio_ccw also provides an I/O region to accept channel program - request from user space and store I/O interrupt result for user - space to retrieve. To notify user space an I/O completion, it offers - an interface to setup an eventfd fd for asynchronous signaling. - -- The vfio_mdev driver for the mediated vfio ccw device. - This is provided by the mdev framework. It is a vfio device driver for - the mdev that created by vfio_ccw. - It realizes a group of vfio device driver callbacks, adds itself to a - vfio group, and registers itself to the mdev framework as a mdev - driver. - It uses a vfio iommu backend that uses the existing map and unmap - ioctls, but rather than programming them into an IOMMU for a device, - it simply stores the translations for use by later requests. This - means that a device programmed in a VM with guest physical addresses - can have the vfio kernel convert that address to process virtual - address, pin the page and program the hardware with the host physical - address in one step. - For a mdev, the vfio iommu backend will not pin the pages during the - VFIO_IOMMU_MAP_DMA ioctl. Mdev framework will only maintain a database - of the iova<->vaddr mappings in this operation. And they export a - vfio_pin_pages and a vfio_unpin_pages interfaces from the vfio iommu - backend for the physical devices to pin and unpin pages by demand. - -Below is a high Level block diagram. - - +-------------+ - | | - | +---------+ | mdev_register_driver() +--------------+ - | | Mdev | +<-----------------------+ | - | | bus | | | vfio_mdev.ko | - | | driver | +----------------------->+ |<-> VFIO user - | +---------+ | probe()/remove() +--------------+ APIs - | | - | MDEV CORE | - | MODULE | - | mdev.ko | - | +---------+ | mdev_register_device() +--------------+ - | |Physical | +<-----------------------+ | - | | device | | | vfio_ccw.ko |<-> subchannel - | |interface| +----------------------->+ | device - | +---------+ | callback +--------------+ - +-------------+ - -The process of how these work together. -1. vfio_ccw.ko drives the physical I/O subchannel, and registers the - physical device (with callbacks) to mdev framework. - When vfio_ccw probing the subchannel device, it registers device - pointer and callbacks to the mdev framework. Mdev related file nodes - under the device node in sysfs would be created for the subchannel - device, namely 'mdev_create', 'mdev_destroy' and - 'mdev_supported_types'. -2. Create a mediated vfio ccw device. - Use the 'mdev_create' sysfs file, we need to manually create one (and - only one for our case) mediated device. -3. vfio_mdev.ko drives the mediated ccw device. - vfio_mdev is also the vfio device drvier. It will probe the mdev and - add it to an iommu_group and a vfio_group. Then we could pass through - the mdev to a guest. - -vfio-ccw I/O region -------------------- - -An I/O region is used to accept channel program request from user -space and store I/O interrupt result for user space to retrieve. The -definition of the region is: - -struct ccw_io_region { -#define ORB_AREA_SIZE 12 - __u8 orb_area[ORB_AREA_SIZE]; -#define SCSW_AREA_SIZE 12 - __u8 scsw_area[SCSW_AREA_SIZE]; -#define IRB_AREA_SIZE 96 - __u8 irb_area[IRB_AREA_SIZE]; - __u32 ret_code; -} __packed; - -While starting an I/O request, orb_area should be filled with the -guest ORB, and scsw_area should be filled with the SCSW of the Virtual -Subchannel. - -irb_area stores the I/O result. - -ret_code stores a return code for each access of the region. - -vfio-ccw operation details --------------------------- - -vfio-ccw follows what vfio-pci did on the s390 platform and uses -vfio-iommu-type1 as the vfio iommu backend. - -* CCW translation APIs - A group of APIs (start with 'cp_') to do CCW translation. The CCWs - passed in by a user space program are organized with their guest - physical memory addresses. These APIs will copy the CCWs into kernel - space, and assemble a runnable kernel channel program by updating the - guest physical addresses with their corresponding host physical addresses. - Note that we have to use IDALs even for direct-access CCWs, as the - referenced memory can be located anywhere, including above 2G. - -* vfio_ccw device driver - This driver utilizes the CCW translation APIs and introduces - vfio_ccw, which is the driver for the I/O subchannel devices you want - to pass through. - vfio_ccw implements the following vfio ioctls: - VFIO_DEVICE_GET_INFO - VFIO_DEVICE_GET_IRQ_INFO - VFIO_DEVICE_GET_REGION_INFO - VFIO_DEVICE_RESET - VFIO_DEVICE_SET_IRQS - This provides an I/O region, so that the user space program can pass a - channel program to the kernel, to do further CCW translation before - issuing them to a real device. - This also provides the SET_IRQ ioctl to setup an event notifier to - notify the user space program the I/O completion in an asynchronous - way. - -The use of vfio-ccw is not limited to QEMU, while QEMU is definitely a -good example to get understand how these patches work. Here is a little -bit more detail how an I/O request triggered by the QEMU guest will be -handled (without error handling). - -Explanation: -Q1-Q7: QEMU side process. -K1-K5: Kernel side process. - -Q1. Get I/O region info during initialization. -Q2. Setup event notifier and handler to handle I/O completion. - -... ... - -Q3. Intercept a ssch instruction. -Q4. Write the guest channel program and ORB to the I/O region. - K1. Copy from guest to kernel. - K2. Translate the guest channel program to a host kernel space - channel program, which becomes runnable for a real device. - K3. With the necessary information contained in the orb passed in - by QEMU, issue the ccwchain to the device. - K4. Return the ssch CC code. -Q5. Return the CC code to the guest. - -... ... - - K5. Interrupt handler gets the I/O result and write the result to - the I/O region. - K6. Signal QEMU to retrieve the result. -Q6. Get the signal and event handler reads out the result from the I/O - region. -Q7. Update the irb for the guest. - -Limitations ------------ - -The current vfio-ccw implementation focuses on supporting basic commands -needed to implement block device functionality (read/write) of DASD/ECKD -device only. Some commands may need special handling in the future, for -example, anything related to path grouping. - -DASD is a kind of storage device. While ECKD is a data recording format. -More information for DASD and ECKD could be found here: -https://en.wikipedia.org/wiki/Direct-access_storage_device -https://en.wikipedia.org/wiki/Count_key_data - -Together with the corresponding work in QEMU, we can bring the passed -through DASD/ECKD device online in a guest now and use it as a block -device. - -While the current code allows the guest to start channel programs via -START SUBCHANNEL, support for HALT SUBCHANNEL or CLEAR SUBCHANNEL is -not yet implemented. - -vfio-ccw supports classic (command mode) channel I/O only. Transport -mode (HPF) is not supported. - -QDIO subchannels are currently not supported. Classic devices other than -DASD/ECKD might work, but have not been tested. - -Reference ---------- -1.

When using "-" all debug areas -are flushed. - -Examples: - -1. Flush debug area 0:: - - > echo "0" > /sys/kernel/debug/s390dbf/dasd/flush - -2. Flush all debug areas:: - - > echo "-" > /sys/kernel/debug/s390dbf/dasd/flush - -Changing the size of debug areas ------------------------------------- -It is possible the change the size of debug areas through piping -the number of pages to the debugfs file "pages". The resize request will -also flush the debug areas. - -Example: - -Define 4 pages for the debug areas of debug feature "dasd":: - - > echo "4" > /sys/kernel/debug/s390dbf/dasd/pages - -Stooping the debug feature --------------------------- -Example: - -1. Check if stopping is allowed:: - - > cat /proc/sys/s390dbf/debug_stoppable - -2. Stop debug feature:: - - > echo 0 > /proc/sys/s390dbf/debug_active - -lcrash Interface ----------------- -It is planned that the dump analysis tool lcrash gets an additional command -'s390dbf' to display all the debug logs. With this tool it will be possible -to investigate the debug logs on a live system and with a memory dump after -a system crash. - -Investigating raw memory ------------------------- -One last possibility to investigate the debug logs at a live -system and after a system crash is to look at the raw memory -under VM or at the Service Element. -It is possible to find the anker of the debug-logs through -the 'debug_area_first' symbol in the System map. Then one has -to follow the correct pointers of the data-structures defined -in debug.h and find the debug-areas in memory. -Normally modules which use the debug feature will also have -a global variable with the pointer to the debug-logs. Following -this pointer it will also be possible to find the debug logs in -memory. - -For this method it is recommended to use '16 * x + 4' byte (x = 0..n) -for the length of the data field in debug_register() in -order to see the debug entries well formatted. - - -Predefined Views ----------------- - -There are three predefined views: hex_ascii, raw and sprintf. -The hex_ascii view shows the data field in hex and ascii representation -(e.g. '45 43 4b 44 | ECKD'). -The raw view returns a bytestream as the debug areas are stored in memory. - -The sprintf view formats the debug entries in the same way as the sprintf -function would do. The sprintf event/exception functions write to the -debug entry a pointer to the format string (size = sizeof(long)) -and for each vararg a long value. So e.g. for a debug entry with a format -string plus two varargs one would need to allocate a (3 * sizeof(long)) -byte data area in the debug_register() function. - -IMPORTANT: - Using "%s" in sprintf event functions is dangerous. You can only - use "%s" in the sprintf event functions, if the memory for the passed string - is available as long as the debug feature exists. The reason behind this is - that due to performance considerations only a pointer to the string is stored - in the debug feature. If you log a string that is freed afterwards, you will - get an OOPS when inspecting the debug feature, because then the debug feature - will access the already freed memory. - -NOTE: - If using the sprintf view do NOT use other event/exception functions - than the sprintf-event and -exception functions. - -The format of the hex_ascii and sprintf view is as follows: - -- Number of area -- Timestamp (formatted as seconds and microseconds since 00:00:00 Coordinated - Universal Time (UTC), January 1, 1970) -- level of debug entry -- Exception flag (* = Exception) -- Cpu-Number of calling task -- Return Address to caller -- data field - -The format of the raw view is: - -- Header as described in debug.h -- datafield - -A typical line of the hex_ascii view will look like the following (first line -is only for explanation and will not be displayed when 'cating' the view): - -area time level exception cpu caller data (hex + ascii) --------------------------------------------------------------------------- -00 00964419409:440690 1 - 00 88023fe - - -Defining views --------------- - -Views are specified with the 'debug_view' structure.

Each CPU will have control of a set of MCA banks in the hardware and these are not shared with other CPUs. For example, bank 0 may be the Load-Store Unit on every logical CPU, but each bank 0 is a unique structure in the hardware. In other words, there isn't a *single* Load-Store Unit at MCA bank 0 that all logical CPUs share. This idea extends even to non-core MCA banks. For example, CPU0 and CPU4 may see a Unified Memory Controller at bank 15, but each CPU is actually seeing a unique hardware structure that is not shared with other CPUs. Because the MCA banks are all unique hardware structures, it would be good to control them in a more granular way. For example, if there is a known issue with the Floating Point Unit on CPU5 and a user wishes to disable an error type on the Floating Point Unit, then it would be good to do this only for CPU5 rather than all CPUs. Also, future AMD systems may have heterogeneous MCA banks. Meaning the bank numbers may not necessarily represent the same types between CPUs. For example, bank 20 visible to CPU0 may be a Unified Memory Controller and bank 20 visible to CPU4 may be a Coherent Slave. So granular control will be even more necessary should the user wish to control specific MCA banks. Split the device attributes from struct mce_bank leaving only the MCA bank control fields. Make struct mce_banks[] per_cpu in order to have more granular control over individual MCA banks in the hardware. Allocate the device attributes statically based on the maximum number of MCA banks supported. The sysfs interface will use as many as needed per CPU. Currently, this is set to mca_cfg.banks, but will be changed to a per_cpu bank count in a future patch. Allocate the MCA control bits statically. This is in order to avoid locking warnings when memory is allocated during secondary CPUs' init sequences. Also, remove the now unnecessary return values from __mcheck_cpu_mce_banks_init() and __mcheck_cpu_cap_init(). Redo the sysfs store/show functions to handle the per_cpu mce_banks[].

However, some banks may be unused in which case the registers for such banks are Read-as-Zero/Writes-Ignored. Also, the OS may avoid setting some control bits because of quirks, etc. A bank can be considered uninitialized if the MCA_CTL register returns zero. This is because either the OS did not write anything or because the hardware is enforcing RAZ/WI for the bank. Set a bank's init value based on if the control bits are set or not in hardware. Return an error code in the sysfs interface for uninitialized banks. Do a final bank init check in a separate function which is not part of any user-controlled code flows. This is so a user may enable/disable a bank during runtime without having to restart their system. [ bp: Massage a bit.

While it works perfectly fine for build-systems where the prefix gets defined anyways for us human beings it's quite an annoying requirement especially given most of time the same one prefix "arc-linux-" is all what we need. It looks like finally we're getting the best of both worlds: 1. W/o cross-toolchain we still may install headers, build .dtb etc 2. W/ cross-toolchain get the kerne built with only ARCH=arc Inspired by [1] & [2].

As of today we adjust memory apertures configuration in U-boot so we have different configuration in case of loading kernel via U-boot and JTAG. It isn't really critical in case of existing platform configuration as configuration differs for unused address space regions or unused AXI masters. However we may face with this issue when we'll bringup new peripherals or touch their address space. Fix that by perform full configuration of memory bridge in HSDK platform code. Basically we simply copy memory bridge configuration code from U-boot.

It is disabled since commit 1be01d4a5714 ("driver: base: Disable CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was made default to 'n', 2. It is not recommended (help message: "This should not be used today [...] creates a high system load") and was kept only for ancient userland, 3. Certain userland specifically requests it to be disabled (systemd README: "Legacy hotplug slows down the system and confuses udev").

If it discovers a pseudo_locksetup group, it breaks out of the loop. This means any later closid doesn't get its used bits added to used_b. These bits will then get set in unused_b, and added to the new control group's configuration, even if they were marked as exclusive for a later closid. When encountering a pseudo_locksetup group, we should continue. This is because "a resource group enters 'pseudo-locked' mode after the schemata is written while the resource group is in 'pseudo-locksetup' mode." When we find a pseudo_locksetup group, its configuration is expected to be overwritten, we can skip it.

So it's useful to expose AVX-512 usage elapsed time as a heuristic hint for user space job schedulers to cluster the AVX-512 using tasks together. Examples: $ while [ 1 ]; do cat /proc/tid/arch_status | grep AVX512; sleep 1; done AVX512_elapsed_ms: 4 AVX512_elapsed_ms: 8 AVX512_elapsed_ms: 4 This means that 4 milliseconds have elapsed since the tsks AVX512 usage was detected when the task was scheduled out. $ cat /proc/tid/arch_status | grep AVX512 AVX512_elapsed_ms: -1 '-1' indicates that no AVX512 usage was recorded for this task. The time exposed is not necessarily accurate when the arch_status file is read as the AVX512 usage is only evaluated when a task is scheduled out. Accurate usage information can be obtained with performance counters.

After consulting the developer documentation for IOP80321 and IOP80331 I can clearly see that this may be useful for IOP80321 family (mach-iop32x) but it is highly dubious for any 80331 series or later chip: in these chips the lines are not multiplexed for UARTs. We convert the code to pass optional GPIO descriptors and register these only on the 80321-based boards where it makes sense, optionally obtain them in the driver and use the gpiod_set_raw_value() to ascertain the line gets driven low when needed. The GPIO driver does not give the GPIO chip a reasonable label so the patch also adds that so that these machine descriptor tables can be used.

Firstly in the Linux page tables, much like other architectures, and secondly in the SLB (Segment Lookaside Buffer) and HPT. It's the SLB and HPT that are actually used by the hardware to do translations. As part of the series adding support for 4PB user virtual address space using the hash MMU, we added support for allocating multiple "context ids" per process, one for each 512TB chunk of address space. These are tracked in an array called extended_id in the mm_context_t of a process that has done a mapping above 512TB. If such a process forks (ie. clone(2) without CLONE_VM set) it's mm is copied, including the mm_context_t, and then init_new_context() is called to reinitialise parts of the mm_context_t as appropriate to separate the address spaces of the two processes. The key step in ensuring the two processes have separate address spaces is to allocate a new context id for the process, this is done at the beginning of hash__init_new_context(). If we didn't allocate a new context id then the two processes would share mappings as far as the SLB and HPT are concerned, even though their Linux page tables would be separate. For mappings above 512TB, which use the extended_id array, we neglected to allocate new context ids on fork, meaning the parent and child use the same ids and therefore share those mappings even though they're supposed to be separate. This can lead to the parent seeing writes done by the child, which is essentially memory corruption. There is an additional exposure which is that if the child process exits, all its context ids are freed, including the context ids that are still in use by the parent for mappings above 512TB. One or more of those ids can then be reallocated to a third process, that process can then read/write to the parent's mappings above 512TB. Additionally if the freed id is used for the third process's primary context id, then the parent is able to read/write to the third process's mappings *below* 512TB. All of these are fundamental failures to enforce separation between processes. The only mitigating factor is that the bug only occurs if a process creates mappings above 512TB, and most applications still do not create such mappings. Only machines using the hash page table MMU are affected, eg. PowerPC 970 (G5), PA6T, Power5/6/7/8/9. By default Power9 bare metal machines (powernv) use the Radix MMU and are not affected, unless the machine has been explicitly booted in HPT mode (using disable_radix on the kernel command line). KVM guests on Power9 may be affected if the host or guest is configured to use the HPT MMU. LPARs under PowerVM on Power9 are affected as they always use the HPT MMU. Kernels built with PAGE_SIZE=4K are not affected. The fix is relatively simple, we need to reallocate context ids for all extended mappings on fork.

KVM_GET_REG_LIST was not changed to match however: instead, it simply yields a list of 32-bit register IDs that together cover the whole kvm_regs struct. This means that if userspace tries to use the resulting list of IDs directly to drive calls to KVM_*_ONE_REG, some of those calls will now fail. This was not the intention. Instead, iterating KVM_*_ONE_REG over the list of IDs returned by KVM_GET_REG_LIST should be guaranteed to work. This patch fixes the problem by splitting validate_core_offset() into a backend core_reg_size_from_offset() which does all of the work except for checking that the size field in the register ID matches, and kvm_arm_copy_reg_indices() and num_core_regs() are converted to use this to enumerate the valid offsets. kvm_arm_copy_reg_indices() now also sets the register ID size field appropriately based on the value returned, so the register ID supplied to userspace is fully qualified for use with the register access ioctls.

This means that the two representations differ when running on a big-endian host. But we blindly copy data from one representation to another when converting between the two, resulting in the register contents being unintentionally byteswapped in certain situations. Currently this can be triggered by the first SVE instruction after a syscall, for example (though the potential trigger points may vary in future). So, fix the conversion functions fpsimd_to_sve(), sve_to_fpsimd() and sve_sync_from_fpsimd_zeropad() to swab where appropriate. There is no common swahl128() or swab128() that we could use here. Maybe it would be worth making this generic, but for now add a simple local hack. Since the byte order differences are exposed in ABI, also clarify the documentation.

However, the way this feature is triggered is a bit confusing. First, it is not used for page faults while a nested guest is running: but this is not an issue since the artificial halt is completely invisible to the guest, either L1 or L2. Second, it is used even if kvm_halt_in_guest() returns true; in this case, the guest probably should not pay the additional latency cost of the artificial halt, and thus we should handle the page fault in a completely synchronous way. By introducing a new function kvm_can_deliver_async_pf, this patch commonizes the code that chooses whether to deliver an async page fault (kvm_arch_async_page_not_present) and the code that chooses whether a page fault should be handled synchronously (kvm_can_do_async_pf).

Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if -you distribute copies of the library, or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link a program with the library, you must provide -complete object files to the recipients so that they can relink them -with the library, after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - Our method of protecting your rights has two steps: (1) copyright -the library, and (2) offer you this license which gives you legal -permission to copy, distribute and/or modify the library. - - Also, for each distributor's protection, we want to make certain -that everyone understands that there is no warranty for this free -library. If the library is modified by someone else and passed on, we -want its recipients to know that what they have is not the original -version, so that any problems introduced by others will not reflect on -the original authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that companies distributing free -software will individually obtain patent licenses, thus in effect -transforming the program into proprietary software. To prevent this, -we have made it clear that any patent must be licensed for everyone's -free use or not licensed at all. - - Most GNU software, including some libraries, is covered by the ordinary -GNU General Public License, which was designed for utility programs. This -license, the GNU Library General Public License, applies to certain -designated libraries. This license is quite different from the ordinary -one; be sure to read it in full, and don't assume that anything in it is -the same as in the ordinary license. - - The reason we have a separate public license for some libraries is that -they blur the distinction we usually make between modifying or adding to a -program and simply using it. Linking a program with a library, without -changing the library, is in some sense simply using the library, and is -analogous to running a utility program or application program. However, in -a textual and legal sense, the linked executable is a combined work, a -derivative of the original library, and the ordinary General Public License -treats it as such. - - Because of this blurred distinction, using the ordinary General -Public License for libraries did not effectively promote software -sharing, because most developers did not use the libraries. We -concluded that weaker conditions might promote sharing better. - - However, unrestricted linking of non-free programs would deprive the -users of those programs of all benefit from the free status of the -libraries themselves. This Library General Public License is intended to -permit developers of non-free programs to use free libraries, while -preserving your freedom as a user of such programs to change the free -libraries that are incorporated in them. (We have not seen how to achieve -this as regards changes in header files, but we have achieved it as regards -changes in the actual functions of the Library.) The hope is that this -will lead to faster development of free libraries. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library". The -former contains code derived from the library, while the latter only -works together with the library. - - Note that it is possible for a library to be covered by the ordinary -General Public License rather than by this special one. - - GNU LIBRARY GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License Agreement applies to any software library which -contains a notice placed by the copyright holder or other authorized -party saying it may be distributed under the terms of this Library -General Public License (also called "this License"). Each licensee is -addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also compile or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - c) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - d) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the source code distributed need not include anything that is normally -distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Library General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change. You can do so by permitting -redistribution under these terms (or, alternatively, under the terms of the -ordinary General Public License). - - To apply these terms, attach the following notices to the library. It is -safest to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least the -"copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Library General Public - License as published by the Free Software Foundation; either - version 2 of the License, or (at your option) any later version. - - This library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU - Library General Public License for more details. - - You should have received a copy of the GNU Library General Public - License along with this library; if not, write to the Free - Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. - -Also add information on how to contact you by electronic and paper mail. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the library, if -necessary.

The function can work or not, but the code logic should never do something different based on this. The only way this can fail is if: * debugfs superblock can not be pinned - something really went wrong with the vfs layer. * file is created with same name - the caller's fault. * new_inode() fails - happens if memory is exhausted. so failing to clean up debugfs properly is the least of the system's sproblems in uch a situation.

The bug is actually in early_p4d_offset() and introduced by commit 12a8cc7fcf54 ("x86/kasan: Use the same shadow offset for 4- and 5-level paging") early_p4d_offset() tries to convert pgd_val(*pgd) value to a physical address. This doesn't make sense because pgd_val() already contains the physical address. It did work prior to commit d52888aa2753 because the result of "__pa_nodebug(pgd_val(*pgd)) & PTE_PFN_MASK" was the same as "pgd_val(*pgd) & PTE_PFN_MASK". __pa_nodebug() just set some high bits which were masked out by applying PTE_PFN_MASK. After the change of the PAGE_OFFSET offset in commit d52888aa2753 __pa_nodebug(pgd_val(*pgd)) started to return a value with more high bits set and PTE_PFN_MASK wasn't enough to mask out all of them. So it returns a wrong not even canonical address and crashes on the attempt to dereference it. Switch back to pgd_val() & PTE_PFN_MASK to cure the issue.

Since there are no GPE blocks defined for use on ARM +platforms, ACPI events must be signaled differently. + +There are two options: GPIO-signaled interrupts (Section 5.6.5), and +interrupt-signaled events (Section 5.6.9). Interrupt-signaled events are a +new feature in the ACPI 6.1 specification. Either - or both - can be used +on a given platform, and which to use may be dependent of limitations in any +given SoC. If possible, interrupt-signaled events are recommended. + + +ACPI Processor Control +---------------------- +Section 8 of the ACPI specification changed significantly in version 6.0. +Processors should now be defined as Device objects with _HID ACPI0007; do +not use the deprecated Processor statement in ASL. All multiprocessor systems +should also define a hierarchy of processors, done with Processor Container +Devices (see Section 8.4.3.1, _HID ACPI0010); do not use processor aggregator +devices (Section 8.5) to describe processor topology. Section 8.4 of the +specification describes the semantics of these object definitions and how +they interrelate. + +Most importantly, the processor hierarchy defined also defines the low power +idle states that are available to the platform, along with the rules for +determining which processors can be turned on or off and the circumstances +that control that. Without this information, the processors will run in +whatever power state they were left in by UEFI. + +Note too, that the processor Device objects defined and the entries in the +MADT for GICs are expected to be in synchronization. The _UID of the Device +object must correspond to processor IDs used in the MADT. + +It is recommended that CPPC (8.4.5) be used as the primary model for processor +performance control on arm64. C-states and P-states may become available at +some point in the future, but most current design work appears to favor CPPC. + +Further, it is essential that the ARMv8 SoC provide a fully functional +implementation of PSCI; this will be the only mechanism supported by ACPI +to control CPU power state. Booting of secondary CPUs using the ACPI +parking protocol is possible, but discouraged, since only PSCI is supported +for ARM servers. + + +ACPI System Address Map Interfaces +---------------------------------- +In Section 15 of the ACPI specification, several methods are mentioned as +possible mechanisms for conveying memory resource information to the kernel. +For arm64, we will only support UEFI for booting with ACPI, hence the UEFI +GetMemoryMap() boot service is the only mechanism that will be used. + + +ACPI Platform Error Interfaces (APEI) +------------------------------------- +The APEI tables supported are described above. + +APEI requires the equivalent of an SCI and an NMI on ARMv8. The SCI is used +to notify the OSPM of errors that have occurred but can be corrected and the +system can continue correct operation, even if possibly degraded. The NMI is +used to indicate fatal errors that cannot be corrected, and require immediate +attention. + +Since there is no direct equivalent of the x86 SCI or NMI, arm64 handles +these slightly differently. The SCI is handled as a high priority interrupt; +given that these are corrected (or correctable) errors being reported, this +is sufficient. The NMI is emulated as the highest priority interrupt +possible. This implies some caution must be used since there could be +interrupts at higher privilege levels or even interrupts at the same priority +as the emulated NMI. In Linux, this should not be the case but one should +be aware it could happen. + + +ACPI Objects Not Supported on ARM64 +----------------------------------- +While this may change in the future, there are several classes of objects +that can be defined, but are not currently of general interest to ARM servers. +Some of these objects have x86 equivalents, and may actually make sense in ARM +servers. However, there is either no hardware available at present, or there +may not even be a non-ARM implementation yet. Hence, they are not currently +supported. + +The following classes of objects are not supported: + + - Section 9.2: ambient light sensor devices + + - Section 9.3: battery devices + + - Section 9.4: lids (e.g., laptop lids) + + - Section 9.8.2: IDE controllers + + - Section 9.9: floppy controllers + + - Section 9.10: GPE block devices + + - Section 9.15: PC/AT RTC/CMOS devices + + - Section 9.16: user presence detection devices + + - Section 9.17: I/O APIC devices; all GICs must be enumerable via MADT + + - Section 9.18: time and alarm devices (see 9.15) + + - Section 10: power source and power meter devices + + - Section 11: thermal management + + - Section 12: embedded controllers interface + + - Section 13: SMBus interfaces + + +This also means that there is no support for the following objects: + +==== =========================== ==== ========== +Name Section Name Section +==== =========================== ==== ========== +_ALC 9.3.4 _FDM 9.10.3 +_ALI 9.3.2 _FIX 6.2.7 +_ALP 9.3.6 _GAI 10.4.5 +_ALR 9.3.5 _GHL 10.4.7 +_ALT 9.3.3 _GTM 9.9.2.1.1 +_BCT 10.2.2.10 _LID 9.5.1 +_BDN 6.5.3 _PAI 10.4.4 +_BIF 10.2.2.1 _PCL 10.3.2 +_BIX 10.2.2.1 _PIF 10.3.3 +_BLT 9.2.3 _PMC 10.4.1 +_BMA 10.2.2.4 _PMD 10.4.8 +_BMC 10.2.2.12 _PMM 10.4.3 +_BMD 10.2.2.11 _PRL 10.3.4 +_BMS 10.2.2.5 _PSR 10.3.1 +_BST 10.2.2.6 _PTP 10.4.2 +_BTH 10.2.2.7 _SBS 10.1.3 +_BTM 10.2.2.9 _SHL 10.4.6 +_BTP 10.2.2.8 _STM 9.9.2.1.1 +_DCK 6.5.2 _UPD 9.16.1 +_EC 12.12 _UPP 9.16.2 +_FDE 9.10.1 _WPC 10.5.2 +_FDI 9.10.2 _WPP 10.5.3 +==== =========================== ==== ========== diff --git a/Documentation/arm64/acpi_object_usage.txt b/Documentation/arm64/acpi_object_usage.txt deleted file mode 100644 index c77010c5c1f0..000000000000 --- a/Documentation/arm64/acpi_object_usage.txt +++ /dev/null @@ -1,622 +0,0 @@ -ACPI Tables ------------ -The expectations of individual ACPI tables are discussed in the list that -follows. - -If a section number is used, it refers to a section number in the ACPI -specification where the object is defined.

It allows the +hardware vendors to take responsibility for power management behaviour without +depending on an OS release cycle which is not under their control. + +ACPI is also important because hardware and OS vendors have already worked +out the mechanisms for supporting a general purpose computing ecosystem. The +infrastructure is in place, the bindings are in place, and the processes are +in place. DT does exactly what Linux needs it to when working with vertically +integrated devices, but there are no good processes for supporting what the +server vendors need. Linux could potentially get there with DT, but doing so +really just duplicates something that already works. ACPI already does what +the hardware vendors need, Microsoft won’t collaborate on DT, and hardware +vendors would still end up providing two completely separate firmware +interfaces -- one for Linux and one for Windows. + + +Kernel Compatibility +-------------------- +One of the primary motivations for ACPI is standardization, and using that +to provide backward compatibility for Linux kernels. In the server market, +software and hardware are often used for long periods. ACPI allows the +kernel and firmware to agree on a consistent abstraction that can be +maintained over time, even as hardware or software change. As long as the +abstraction is supported, systems can be updated without necessarily having +to replace the kernel. + +When a Linux driver or subsystem is first implemented using ACPI, it by +definition ends up requiring a specific version of the ACPI specification +-- it's baseline. ACPI firmware must continue to work, even though it may +not be optimal, with the earliest kernel version that first provides support +for that baseline version of ACPI. There may be a need for additional drivers, +but adding new functionality (e.g., CPU power management) should not break +older kernel versions. Further, ACPI firmware must also work with the most +recent version of the kernel. + + +Relationship with Device Tree +----------------------------- +ACPI support in drivers and subsystems for ARMv8 should never be mutually +exclusive with DT support at compile time. + +At boot time the kernel will only use one description method depending on +parameters passed from the boot loader (including kernel bootargs). + +Regardless of whether DT or ACPI is used, the kernel must always be capable +of booting with either scheme (in kernels with both schemes enabled at compile +time). + + +Booting using ACPI tables +------------------------- +The only defined method for passing ACPI tables to the kernel on ARMv8 +is via the UEFI system configuration table. Just so it is explicit, this +means that ACPI is only supported on platforms that boot via UEFI. + +When an ARMv8 system boots, it can either have DT information, ACPI tables, +or in some very unusual cases, both. If no command line parameters are used, +the kernel will try to use DT for device enumeration; if there is no DT +present, the kernel will try to use ACPI tables, but only if they are present. +In neither is available, the kernel will not boot. If acpi=force is used +on the command line, the kernel will attempt to use ACPI tables first, but +fall back to DT if there are no ACPI tables present. The basic idea is that +the kernel will not fail to boot unless it absolutely has no other choice. + +Processing of ACPI tables may be disabled by passing acpi=off on the kernel +command line; this is the default behavior. + +In order for the kernel to load and use ACPI tables, the UEFI implementation +MUST set the ACPI_20_TABLE_GUID to point to the RSDP table (the table with +the ACPI signature "RSD PTR "). If this pointer is incorrect and acpi=force +is used, the kernel will disable ACPI and try to use DT to boot instead; the +kernel has, in effect, determined that ACPI tables are not present at that +point. + +If the pointer to the RSDP table is correct, the table will be mapped into +the kernel by the ACPI core, using the address provided by UEFI. + +The ACPI core will then locate and map in all other ACPI tables provided by +using the addresses in the RSDP table to find the XSDT (eXtended System +Description Table). The XSDT in turn provides the addresses to all other +ACPI tables provided by the system firmware; the ACPI core will then traverse +this table and map in the tables listed. + +The ACPI core will ignore any provided RSDT (Root System Description Table). +RSDTs have been deprecated and are ignored on arm64 since they only allow +for 32-bit addresses. + +Further, the ACPI core will only use the 64-bit address fields in the FADT +(Fixed ACPI Description Table). Any 32-bit address fields in the FADT will +be ignored on arm64. + +Hardware reduced mode (see Section 4.1 of the ACPI 6.1 specification) will +be enforced by the ACPI core on arm64. Doing so allows the ACPI core to +run less complex code since it no longer has to provide support for legacy +hardware from other architectures. Any fields that are not to be used for +hardware reduced mode must be set to zero. + +For the ACPI core to operate properly, and in turn provide the information +the kernel needs to configure devices, it expects to find the following +tables (all section numbers refer to the ACPI 6.1 specification): + + - RSDP (Root System Description Pointer), section 5.2.5 + + - XSDT (eXtended System Description Table), section 5.2.8 + + - FADT (Fixed ACPI Description Table), section 5.2.9 + + - DSDT (Differentiated System Description Table), section + 5.2.11.1 + + - MADT (Multiple APIC Description Table), section 5.2.12 + + - GTDT (Generic Timer Description Table), section 5.2.24 + + - If PCI is supported, the MCFG (Memory mapped ConFiGuration + Table), section 5.2.6, specifically Table 5-31. + + - If booting without a console= kernel parameter is + supported, the SPCR (Serial Port Console Redirection table), + section 5.2.6, specifically Table 5-31. + + - If necessary to describe the I/O topology, SMMUs and GIC ITSs, + the IORT (Input Output Remapping Table, section 5.2.6, specifically + Table 5-31). + + - If NUMA is supported, the SRAT (System Resource Affinity Table) + and SLIT (System Locality distance Information Table), sections + 5.2.16 and 5.2.17, respectively. + +If the above tables are not all present, the kernel may or may not be +able to boot properly since it may not be able to configure all of the +devices available. This list of tables is not meant to be all inclusive; +in some environments other tables may be needed (e.g., any of the APEI +tables from section 18) to support specific functionality. + + +ACPI Detection +-------------- +Drivers should determine their probe() type by checking for a null +value for ACPI_HANDLE, or checking .of_node, or other information in +the device structure. This is detailed further in the "Driver +Recommendations" section. + +In non-driver code, if the presence of ACPI needs to be detected at +run time, then check the value of acpi_disabled. If CONFIG_ACPI is not +set, acpi_disabled will always be 1. + + +Device Enumeration +------------------ +Device descriptions in ACPI should use standard recognized ACPI interfaces. +These may contain less information than is typically provided via a Device +Tree description for the same device. This is also one of the reasons that +ACPI can be useful -- the driver takes into account that it may have less +detailed information about the device and uses sensible defaults instead. +If done properly in the driver, the hardware can change and improve over +time without the driver having to change at all. + +Clocks provide an excellent example. In DT, clocks need to be specified +and the drivers need to take them into account. In ACPI, the assumption +is that UEFI will leave the device in a reasonable default state, including +any clock settings. If for some reason the driver needs to change a clock +value, this can be done in an ACPI method; all the driver needs to do is +invoke the method and not concern itself with what the method needs to do +to change the clock. Changing the hardware can then take place over time +by changing what the ACPI method does, and not the driver. + +In DT, the parameters needed by the driver to set up clocks as in the example +above are known as "bindings"; in ACPI, these are known as "Device Properties" +and provided to a driver via the _DSD object. + +ACPI tables are described with a formal language called ASL, the ACPI +Source Language (section 19 of the specification). This means that there +are always multiple ways to describe the same thing -- including device +properties. For example, device properties could use an ASL construct +that looks like this: Name(KEY0, "value0"). An ACPI device driver would +then retrieve the value of the property by evaluating the KEY0 object. +However, using Name() this way has multiple problems: (1) ACPI limits +names ("KEY0") to four characters unlike DT; (2) there is no industry +wide registry that maintains a list of names, minimizing re-use; (3) +there is also no registry for the definition of property values ("value0"), +again making re-use difficult; and (4) how does one maintain backward +compatibility as new hardware comes out? The _DSD method was created +to solve precisely these sorts of problems; Linux drivers should ALWAYS +use the _DSD method for device properties and nothing else. + +The _DSM object (ACPI Section 9.14.1) could also be used for conveying +device properties to a driver. Linux drivers should only expect it to +be used if _DSD cannot represent the data required, and there is no way +to create a new UUID for the _DSD object. Note that there is even less +regulation of the use of _DSM than there is of _DSD. Drivers that depend +on the contents of _DSM objects will be more difficult to maintain over +time because of this; as of this writing, the use of _DSM is the cause +of quite a few firmware problems and is not recommended. + +Drivers should look for device properties in the _DSD object ONLY; the _DSD +object is described in the ACPI specification section 6.2.5, but this only +describes how to define the structure of an object returned via _DSD, and +how specific data structures are defined by specific UUIDs. Linux should +only use the _DSD Device Properties UUID [5]: + + - UUID: daffd814-6eba-4d8c-8a91-bc9bbf4aa301 + + - http://www.uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf + +The UEFI Forum provides a mechanism for registering device properties [4] +so that they may be used across all operating systems supporting ACPI. +Device properties that have not been registered with the UEFI Forum should +not be used. + +Before creating new device properties, check to be sure that they have not +been defined before and either registered in the Linux kernel documentation +as DT bindings, or the UEFI Forum as device properties. While we do not want +to simply move all DT bindings into ACPI device properties, we can learn from +what has been previously defined. + +If it is necessary to define a new device property, or if it makes sense to +synthesize the definition of a binding so it can be used in any firmware, +both DT bindings and ACPI device properties for device drivers have review +processes. Use them both. When the driver itself is submitted for review +to the Linux mailing lists, the device property definitions needed must be +submitted at the same time. A driver that supports ACPI and uses device +properties will not be considered complete without their definitions. Once +the device property has been accepted by the Linux community, it must be +registered with the UEFI Forum [4], which will review it again for consistency +within the registry. This may require iteration. The UEFI Forum, though, +will always be the canonical site for device property definitions. + +It may make sense to provide notice to the UEFI Forum that there is the +intent to register a previously unused device property name as a means of +reserving the name for later use. Other operating system vendors will +also be submitting registration requests and this may help smooth the +process. + +Once registration and review have been completed, the kernel provides an +interface for looking up device properties in a manner independent of +whether DT or ACPI is being used. This API should be used [6]; it can +eliminate some duplication of code paths in driver probing functions and +discourage divergence between DT bindings and ACPI device properties. + + +Programmable Power Control Resources +------------------------------------ +Programmable power control resources include such resources as voltage/current +providers (regulators) and clock sources. + +With ACPI, the kernel clock and regulator framework is not expected to be used +at all. + +The kernel assumes that power control of these resources is represented with +Power Resource Objects (ACPI section 7.1). The ACPI core will then handle +correctly enabling and disabling resources as they are needed. In order to +get that to work, ACPI assumes each device has defined D-states and that these +can be controlled through the optional ACPI methods _PS0, _PS1, _PS2, and _PS3; +in ACPI, _PS0 is the method to invoke to turn a device full on, and _PS3 is for +turning a device full off. + +There are two options for using those Power Resources. They can: + + - be managed in a _PSx method which gets called on entry to power + state Dx. + + - be declared separately as power resources with their own _ON and _OFF + methods. They are then tied back to D-states for a particular device + via _PRx which specifies which power resources a device needs to be on + while in Dx. Kernel then tracks number of devices using a power resource + and calls _ON/_OFF as needed. + +The kernel ACPI code will also assume that the _PSx methods follow the normal +ACPI rules for such methods: + + - If either _PS0 or _PS3 is implemented, then the other method must also + be implemented. + + - If a device requires usage or setup of a power resource when on, the ASL + should organize that it is allocated/enabled using the _PS0 method. + + - Resources allocated or enabled in the _PS0 method should be disabled + or de-allocated in the _PS3 method. + + - Firmware will leave the resources in a reasonable state before handing + over control to the kernel. + +Such code in _PSx methods will of course be very platform specific. But, +this allows the driver to abstract out the interface for operating the device +and avoid having to read special non-standard values from ACPI tables. Further, +abstracting the use of these resources allows the hardware to change over time +without requiring updates to the driver. + + +Clocks +------ +ACPI makes the assumption that clocks are initialized by the firmware -- +UEFI, in this case -- to some working value before control is handed over +to the kernel. This has implications for devices such as UARTs, or SoC-driven +LCD displays, for example. + +When the kernel boots, the clocks are assumed to be set to reasonable +working values. If for some reason the frequency needs to change -- e.g., +throttling for power management -- the device driver should expect that +process to be abstracted out into some ACPI method that can be invoked +(please see the ACPI specification for further recommendations on standard +methods to be expected). The only exceptions to this are CPU clocks where +CPPC provides a much richer interface than ACPI methods. If the clocks +are not set, there is no direct way for Linux to control them. + +If an SoC vendor wants to provide fine-grained control of the system clocks, +they could do so by providing ACPI methods that could be invoked by Linux +drivers. However, this is NOT recommended and Linux drivers should NOT use +such methods, even if they are provided. Such methods are not currently +standardized in the ACPI specification, and using them could tie a kernel +to a very specific SoC, or tie an SoC to a very specific version of the +kernel, both of which we are trying to avoid. + + +Driver Recommendations +---------------------- +DO NOT remove any DT handling when adding ACPI support for a driver. The +same device may be used on many different systems. + +DO try to structure the driver so that it is data-driven. That is, set up +a struct containing internal per-device state based on defaults and whatever +else must be discovered by the driver probe function. Then, have the rest +of the driver operate off of the contents of that struct. Doing so should +allow most divergence between ACPI and DT functionality to be kept local to +the probe function instead of being scattered throughout the driver. For +example:: + + static int device_probe_dt(struct platform_device *pdev) + { + /* DT specific functionality */ + ... + } + + static int device_probe_acpi(struct platform_device *pdev) + { + /* ACPI specific functionality */ + ... + } + + static int device_probe(struct platform_device *pdev) + { + ... + struct device_node node = pdev->dev.of_node; + ... + + if (node) + ret = device_probe_dt(pdev); + else if (ACPI_HANDLE(&pdev->dev)) + ret = device_probe_acpi(pdev); + else + /* other initialization */ + ... + /* Continue with any generic probe operations */ + ... + } + +DO keep the MODULE_DEVICE_TABLE entries together in the driver to make it +clear the different names the driver is probed for, both from DT and from +ACPI:: + + static struct of_device_id virtio_mmio_match[] = { + { .compatible = "virtio,mmio", }, + { } + }; + MODULE_DEVICE_TABLE(of, virtio_mmio_match); + + static const struct acpi_device_id virtio_mmio_acpi_match[] = { + { "LNRO0005", }, + { } + }; + MODULE_DEVICE_TABLE(acpi, virtio_mmio_acpi_match); + + +ASWG +---- +The ACPI specification changes regularly. During the year 2014, for instance, +version 5.1 was released and version 6.0 substantially completed, with most of +the changes being driven by ARM-specific requirements. Proposed changes are +presented and discussed in the ASWG (ACPI Specification Working Group) which +is a part of the UEFI Forum. The current version of the ACPI specification +is 6.1 release in January 2016. + +Participation in this group is open to all UEFI members. Please see +http://www.uefi.org/workinggroup for details on group membership. + +It is the intent of the ARMv8 ACPI kernel code to follow the ACPI specification +as closely as possible, and to only implement functionality that complies with +the released standards from UEFI ASWG. As a practical matter, there will be +vendors that provide bad ACPI tables or violate the standards in some way. +If this is because of errors, quirks and fix-ups may be necessary, but will +be avoided if possible. If there are features missing from ACPI that preclude +it from being used on a platform, ECRs (Engineering Change Requests) should be +submitted to ASWG and go through the normal approval process; for those that +are not UEFI members, many other members of the Linux community are and would +likely be willing to assist in submitting ECRs. + + +Linux Code +---------- +Individual items specific to Linux on ARM, contained in the the Linux +source code, are in the list that follows: + +ACPI_OS_NAME + This macro defines the string to be returned when + an ACPI method invokes the _OS method.

As long as the -abstraction is supported, systems can be updated without necessarily having -to replace the kernel. - -When a Linux driver or subsystem is first implemented using ACPI, it by -definition ends up requiring a specific version of the ACPI specification --- it's baseline. ACPI firmware must continue to work, even though it may -not be optimal, with the earliest kernel version that first provides support -for that baseline version of ACPI. There may be a need for additional drivers, -but adding new functionality (e.g., CPU power management) should not break -older kernel versions. Further, ACPI firmware must also work with the most -recent version of the kernel. - - -Relationship with Device Tree ------------------------------ -ACPI support in drivers and subsystems for ARMv8 should never be mutually -exclusive with DT support at compile time. - -At boot time the kernel will only use one description method depending on -parameters passed from the boot loader (including kernel bootargs). - -Regardless of whether DT or ACPI is used, the kernel must always be capable -of booting with either scheme (in kernels with both schemes enabled at compile -time). - - -Booting using ACPI tables -------------------------- -The only defined method for passing ACPI tables to the kernel on ARMv8 -is via the UEFI system configuration table. Just so it is explicit, this -means that ACPI is only supported on platforms that boot via UEFI. - -When an ARMv8 system boots, it can either have DT information, ACPI tables, -or in some very unusual cases, both. If no command line parameters are used, -the kernel will try to use DT for device enumeration; if there is no DT -present, the kernel will try to use ACPI tables, but only if they are present. -In neither is available, the kernel will not boot. If acpi=force is used -on the command line, the kernel will attempt to use ACPI tables first, but -fall back to DT if there are no ACPI tables present. The basic idea is that -the kernel will not fail to boot unless it absolutely has no other choice. - -Processing of ACPI tables may be disabled by passing acpi=off on the kernel -command line; this is the default behavior. - -In order for the kernel to load and use ACPI tables, the UEFI implementation -MUST set the ACPI_20_TABLE_GUID to point to the RSDP table (the table with -the ACPI signature "RSD PTR "). If this pointer is incorrect and acpi=force -is used, the kernel will disable ACPI and try to use DT to boot instead; the -kernel has, in effect, determined that ACPI tables are not present at that -point. - -If the pointer to the RSDP table is correct, the table will be mapped into -the kernel by the ACPI core, using the address provided by UEFI. - -The ACPI core will then locate and map in all other ACPI tables provided by -using the addresses in the RSDP table to find the XSDT (eXtended System -Description Table). The XSDT in turn provides the addresses to all other -ACPI tables provided by the system firmware; the ACPI core will then traverse -this table and map in the tables listed. - -The ACPI core will ignore any provided RSDT (Root System Description Table). -RSDTs have been deprecated and are ignored on arm64 since they only allow -for 32-bit addresses. - -Further, the ACPI core will only use the 64-bit address fields in the FADT -(Fixed ACPI Description Table). Any 32-bit address fields in the FADT will -be ignored on arm64. - -Hardware reduced mode (see Section 4.1 of the ACPI 6.1 specification) will -be enforced by the ACPI core on arm64. Doing so allows the ACPI core to -run less complex code since it no longer has to provide support for legacy -hardware from other architectures. Any fields that are not to be used for -hardware reduced mode must be set to zero. - -For the ACPI core to operate properly, and in turn provide the information -the kernel needs to configure devices, it expects to find the following -tables (all section numbers refer to the ACPI 6.1 specification): - - -- RSDP (Root System Description Pointer), section 5.2.5 - - -- XSDT (eXtended System Description Table), section 5.2.8 - - -- FADT (Fixed ACPI Description Table), section 5.2.9 - - -- DSDT (Differentiated System Description Table), section - 5.2.11.1 - - -- MADT (Multiple APIC Description Table), section 5.2.12 - - -- GTDT (Generic Timer Description Table), section 5.2.24 - - -- If PCI is supported, the MCFG (Memory mapped ConFiGuration - Table), section 5.2.6, specifically Table 5-31. - - -- If booting without a console= kernel parameter is - supported, the SPCR (Serial Port Console Redirection table), - section 5.2.6, specifically Table 5-31. - - -- If necessary to describe the I/O topology, SMMUs and GIC ITSs, - the IORT (Input Output Remapping Table, section 5.2.6, specifically - Table 5-31). - - -- If NUMA is supported, the SRAT (System Resource Affinity Table) - and SLIT (System Locality distance Information Table), sections - 5.2.16 and 5.2.17, respectively. - -If the above tables are not all present, the kernel may or may not be -able to boot properly since it may not be able to configure all of the -devices available. This list of tables is not meant to be all inclusive; -in some environments other tables may be needed (e.g., any of the APEI -tables from section 18) to support specific functionality. - - -ACPI Detection --------------- -Drivers should determine their probe() type by checking for a null -value for ACPI_HANDLE, or checking .of_node, or other information in -the device structure. This is detailed further in the "Driver -Recommendations" section. - -In non-driver code, if the presence of ACPI needs to be detected at -run time, then check the value of acpi_disabled. If CONFIG_ACPI is not -set, acpi_disabled will always be 1. - - -Device Enumeration ------------------- -Device descriptions in ACPI should use standard recognized ACPI interfaces. -These may contain less information than is typically provided via a Device -Tree description for the same device. This is also one of the reasons that -ACPI can be useful -- the driver takes into account that it may have less -detailed information about the device and uses sensible defaults instead. -If done properly in the driver, the hardware can change and improve over -time without the driver having to change at all. - -Clocks provide an excellent example. In DT, clocks need to be specified -and the drivers need to take them into account. In ACPI, the assumption -is that UEFI will leave the device in a reasonable default state, including -any clock settings. If for some reason the driver needs to change a clock -value, this can be done in an ACPI method; all the driver needs to do is -invoke the method and not concern itself with what the method needs to do -to change the clock. Changing the hardware can then take place over time -by changing what the ACPI method does, and not the driver. - -In DT, the parameters needed by the driver to set up clocks as in the example -above are known as "bindings"; in ACPI, these are known as "Device Properties" -and provided to a driver via the _DSD object. - -ACPI tables are described with a formal language called ASL, the ACPI -Source Language (section 19 of the specification). This means that there -are always multiple ways to describe the same thing -- including device -properties. For example, device properties could use an ASL construct -that looks like this: Name(KEY0, "value0"). An ACPI device driver would -then retrieve the value of the property by evaluating the KEY0 object. -However, using Name() this way has multiple problems: (1) ACPI limits -names ("KEY0") to four characters unlike DT; (2) there is no industry -wide registry that maintains a list of names, minimizing re-use; (3) -there is also no registry for the definition of property values ("value0"), -again making re-use difficult; and (4) how does one maintain backward -compatibility as new hardware comes out? The _DSD method was created -to solve precisely these sorts of problems; Linux drivers should ALWAYS -use the _DSD method for device properties and nothing else. - -The _DSM object (ACPI Section 9.14.1) could also be used for conveying -device properties to a driver. Linux drivers should only expect it to -be used if _DSD cannot represent the data required, and there is no way -to create a new UUID for the _DSD object. Note that there is even less -regulation of the use of _DSM than there is of _DSD. Drivers that depend -on the contents of _DSM objects will be more difficult to maintain over -time because of this; as of this writing, the use of _DSM is the cause -of quite a few firmware problems and is not recommended. - -Drivers should look for device properties in the _DSD object ONLY; the _DSD -object is described in the ACPI specification section 6.2.5, but this only -describes how to define the structure of an object returned via _DSD, and -how specific data structures are defined by specific UUIDs. Linux should -only use the _DSD Device Properties UUID [5]: - - -- UUID: daffd814-6eba-4d8c-8a91-bc9bbf4aa301 - - -- http://www.uefi.org/sites/default/files/resources/_DSD-device-properties-UUID.pdf - -The UEFI Forum provides a mechanism for registering device properties [4] -so that they may be used across all operating systems supporting ACPI. -Device properties that have not been registered with the UEFI Forum should -not be used. - -Before creating new device properties, check to be sure that they have not -been defined before and either registered in the Linux kernel documentation -as DT bindings, or the UEFI Forum as device properties. While we do not want -to simply move all DT bindings into ACPI device properties, we can learn from -what has been previously defined. - -If it is necessary to define a new device property, or if it makes sense to -synthesize the definition of a binding so it can be used in any firmware, -both DT bindings and ACPI device properties for device drivers have review -processes. Use them both. When the driver itself is submitted for review -to the Linux mailing lists, the device property definitions needed must be -submitted at the same time. A driver that supports ACPI and uses device -properties will not be considered complete without their definitions. Once -the device property has been accepted by the Linux community, it must be -registered with the UEFI Forum [4], which will review it again for consistency -within the registry. This may require iteration. The UEFI Forum, though, -will always be the canonical site for device property definitions. - -It may make sense to provide notice to the UEFI Forum that there is the -intent to register a previously unused device property name as a means of -reserving the name for later use. Other operating system vendors will -also be submitting registration requests and this may help smooth the -process. - -Once registration and review have been completed, the kernel provides an -interface for looking up device properties in a manner independent of -whether DT or ACPI is being used. This API should be used [6]; it can -eliminate some duplication of code paths in driver probing functions and -discourage divergence between DT bindings and ACPI device properties. - - -Programmable Power Control Resources ------------------------------------- -Programmable power control resources include such resources as voltage/current -providers (regulators) and clock sources. - -With ACPI, the kernel clock and regulator framework is not expected to be used -at all. - -The kernel assumes that power control of these resources is represented with -Power Resource Objects (ACPI section 7.1). The ACPI core will then handle -correctly enabling and disabling resources as they are needed. In order to -get that to work, ACPI assumes each device has defined D-states and that these -can be controlled through the optional ACPI methods _PS0, _PS1, _PS2, and _PS3; -in ACPI, _PS0 is the method to invoke to turn a device full on, and _PS3 is for -turning a device full off. - -There are two options for using those Power Resources. They can: - - -- be managed in a _PSx method which gets called on entry to power - state Dx. - - -- be declared separately as power resources with their own _ON and _OFF - methods. They are then tied back to D-states for a particular device - via _PRx which specifies which power resources a device needs to be on - while in Dx. Kernel then tracks number of devices using a power resource - and calls _ON/_OFF as needed. - -The kernel ACPI code will also assume that the _PSx methods follow the normal -ACPI rules for such methods: - - -- If either _PS0 or _PS3 is implemented, then the other method must also - be implemented. - - -- If a device requires usage or setup of a power resource when on, the ASL - should organize that it is allocated/enabled using the _PS0 method. - - -- Resources allocated or enabled in the _PS0 method should be disabled - or de-allocated in the _PS3 method. - - -- Firmware will leave the resources in a reasonable state before handing - over control to the kernel. - -Such code in _PSx methods will of course be very platform specific. But, -this allows the driver to abstract out the interface for operating the device -and avoid having to read special non-standard values from ACPI tables. Further, -abstracting the use of these resources allows the hardware to change over time -without requiring updates to the driver. - - -Clocks ------- -ACPI makes the assumption that clocks are initialized by the firmware -- -UEFI, in this case -- to some working value before control is handed over -to the kernel. This has implications for devices such as UARTs, or SoC-driven -LCD displays, for example. - -When the kernel boots, the clocks are assumed to be set to reasonable -working values. If for some reason the frequency needs to change -- e.g., -throttling for power management -- the device driver should expect that -process to be abstracted out into some ACPI method that can be invoked -(please see the ACPI specification for further recommendations on standard -methods to be expected). The only exceptions to this are CPU clocks where -CPPC provides a much richer interface than ACPI methods. If the clocks -are not set, there is no direct way for Linux to control them. - -If an SoC vendor wants to provide fine-grained control of the system clocks, -they could do so by providing ACPI methods that could be invoked by Linux -drivers. However, this is NOT recommended and Linux drivers should NOT use -such methods, even if they are provided. Such methods are not currently -standardized in the ACPI specification, and using them could tie a kernel -to a very specific SoC, or tie an SoC to a very specific version of the -kernel, both of which we are trying to avoid. - - -Driver Recommendations ----------------------- -DO NOT remove any DT handling when adding ACPI support for a driver. The -same device may be used on many different systems. - -DO try to structure the driver so that it is data-driven. That is, set up -a struct containing internal per-device state based on defaults and whatever -else must be discovered by the driver probe function. Then, have the rest -of the driver operate off of the contents of that struct. Doing so should -allow most divergence between ACPI and DT functionality to be kept local to -the probe function instead of being scattered throughout the driver. For -example: - -static int device_probe_dt(struct platform_device *pdev) -{ - /* DT specific functionality */ - ... -} - -static int device_probe_acpi(struct platform_device *pdev) -{ - /* ACPI specific functionality */ - ... -} - -static int device_probe(struct platform_device *pdev) -{ - ... - struct device_node node = pdev->dev.of_node; - ... - - if (node) - ret = device_probe_dt(pdev); - else if (ACPI_HANDLE(&pdev->dev)) - ret = device_probe_acpi(pdev); - else - /* other initialization */ - ... - /* Continue with any generic probe operations */ - ... -} - -DO keep the MODULE_DEVICE_TABLE entries together in the driver to make it -clear the different names the driver is probed for, both from DT and from -ACPI: - -static struct of_device_id virtio_mmio_match[] = { - { .compatible = "virtio,mmio", }, - { } -}; -MODULE_DEVICE_TABLE(of, virtio_mmio_match); - -static const struct acpi_device_id virtio_mmio_acpi_match[] = { - { "LNRO0005", }, - { } -}; -MODULE_DEVICE_TABLE(acpi, virtio_mmio_acpi_match); - - -ASWG ----- -The ACPI specification changes regularly. During the year 2014, for instance, -version 5.1 was released and version 6.0 substantially completed, with most of -the changes being driven by ARM-specific requirements. Proposed changes are -presented and discussed in the ASWG (ACPI Specification Working Group) which -is a part of the UEFI Forum. The current version of the ACPI specification -is 6.1 release in January 2016. - -Participation in this group is open to all UEFI members. Please see -http://www.uefi.org/workinggroup for details on group membership. - -It is the intent of the ARMv8 ACPI kernel code to follow the ACPI specification -as closely as possible, and to only implement functionality that complies with -the released standards from UEFI ASWG. As a practical matter, there will be -vendors that provide bad ACPI tables or violate the standards in some way. -If this is because of errors, quirks and fix-ups may be necessary, but will -be avoided if possible. If there are features missing from ACPI that preclude -it from being used on a platform, ECRs (Engineering Change Requests) should be -submitted to ASWG and go through the normal approval process; for those that -are not UEFI members, many other members of the Linux community are and would -likely be willing to assist in submitting ECRs. - - -Linux Code ----------- -Individual items specific to Linux on ARM, contained in the the Linux -source code, are in the list that follows: - -ACPI_OS_NAME This macro defines the string to be returned when - an ACPI method invokes the _OS method. On ARM64 - systems, this macro will be "Linux" by default. - The command line parameter acpi_os= - can be used to set it to some other value.

Setup and initialise RAM +--------------------------- + +Requirement: MANDATORY + +The boot loader is expected to find and initialise all RAM that the +kernel will use for volatile data storage in the system.

(It may use internal algorithms +to automatically locate and size all RAM, or it may use knowledge of +the RAM in the machine, or any other method the boot loader designer +sees fit.) + + +2. Setup the device tree +------------------------- + +Requirement: MANDATORY + +The device tree blob (dtb) must be placed on an 8-byte boundary and must +not exceed 2 megabytes in size. Since the dtb will be mapped cacheable +using blocks of up to 2 megabytes in size, it must not be placed within +any 2M region which must be mapped with any specific attributes. + +NOTE: versions prior to v4.2 also require that the DTB be placed within +the 512 MB region starting at text_offset bytes below the kernel Image. + +3. Decompress the kernel image +------------------------------ + +Requirement: OPTIONAL + +The AArch64 kernel does not currently provide a decompressor and +therefore requires decompression (gzip etc.) to be performed by the boot +loader if a compressed Image target (e.g. Image.gz) is used. For +bootloaders that do not implement this requirement, the uncompressed +Image target is available instead. + + +4. Call the kernel image +------------------------ + +Requirement: MANDATORY + +The decompressed kernel image contains a 64-byte header as follows:: + + u32 code0; /* Executable code */ + u32 code1; /* Executable code */ + u64 text_offset; /* Image load offset, little endian */ + u64 image_size; /* Effective Image size, little endian */ + u64 flags; /* kernel flags, little endian */ + u64 res2 = 0; /* reserved */ + u64 res3 = 0; /* reserved */ + u64 res4 = 0; /* reserved */ + u32 magic = 0x644d5241; /* Magic number, little endian, "ARM\x64" */ + u32 res5; /* reserved (used for PE COFF offset) */ + + +Header notes: + +- As of v3.17, all fields are little endian unless stated otherwise. + +- code0/code1 are responsible for branching to stext. + +- when booting through EFI, code0/code1 are initially skipped. + res5 is an offset to the PE header and the PE header has the EFI + entry point (efi_stub_entry).

EL3 is the highest priority level and exists only in secure mode. - -For the purposes of this document, we will use the term `boot loader' -simply to define all software that executes on the CPU(s) before control -is passed to the Linux kernel. This may include secure monitor and -hypervisor code, or it may just be a handful of instructions for -preparing a minimal boot environment. - -Essentially, the boot loader should provide (as a minimum) the -following: - -1. Setup and initialise the RAM -2. Setup the device tree -3. Decompress the kernel image -4. Call the kernel image - - -1. Setup and initialise RAM ---------------------------- - -Requirement: MANDATORY - -The boot loader is expected to find and initialise all RAM that the -kernel will use for volatile data storage in the system. It performs -this in a machine dependent manner. (It may use internal algorithms -to automatically locate and size all RAM, or it may use knowledge of -the RAM in the machine, or any other method the boot loader designer -sees fit.) - - -2. Setup the device tree -------------------------- - -Requirement: MANDATORY - -The device tree blob (dtb) must be placed on an 8-byte boundary and must -not exceed 2 megabytes in size. Since the dtb will be mapped cacheable -using blocks of up to 2 megabytes in size, it must not be placed within -any 2M region which must be mapped with any specific attributes. - -NOTE: versions prior to v4.2 also require that the DTB be placed within -the 512 MB region starting at text_offset bytes below the kernel Image. - -3. Decompress the kernel image ------------------------------- - -Requirement: OPTIONAL - -The AArch64 kernel does not currently provide a decompressor and -therefore requires decompression (gzip etc.) to be performed by the boot -loader if a compressed Image target (e.g. Image.gz) is used. For -bootloaders that do not implement this requirement, the uncompressed -Image target is available instead. - - -4. Call the kernel image ------------------------- - -Requirement: MANDATORY - -The decompressed kernel image contains a 64-byte header as follows: - - u32 code0; /* Executable code */ - u32 code1; /* Executable code */ - u64 text_offset; /* Image load offset, little endian */ - u64 image_size; /* Effective Image size, little endian */ - u64 flags; /* kernel flags, little endian */ - u64 res2 = 0; /* reserved */ - u64 res3 = 0; /* reserved */ - u64 res4 = 0; /* reserved */ - u32 magic = 0x644d5241; /* Magic number, little endian, "ARM\x64" */ - u32 res5; /* reserved (used for PE COFF offset) */ - - -Header notes: - -- As of v3.17, all fields are little endian unless stated otherwise. - -- code0/code1 are responsible for branching to stext. - -- when booting through EFI, code0/code1 are initially skipped. - res5 is an offset to the PE header and the PE header has the EFI - entry point (efi_stub_entry). When the stub has done its work, it - jumps to code0 to resume the normal boot process. - -- Prior to v3.17, the endianness of text_offset was not specified. In - these cases image_size is zero and text_offset is 0x80000 in the - endianness of the kernel. Where image_size is non-zero image_size is - little-endian and must be respected. Where image_size is zero, - text_offset can be assumed to be 0x80000. - -- The flags field (introduced in v3.17) is a little-endian 64-bit field - composed as follows: - Bit 0: Kernel endianness. 1 if BE, 0 if LE. - Bit 1-2: Kernel Page size. - 0 - Unspecified. - 1 - 4K - 2 - 16K - 3 - 64K - Bit 3: Kernel physical placement - 0 - 2MB aligned base should be as close as possible - to the base of DRAM, since memory below it is not - accessible via the linear mapping - 1 - 2MB aligned base may be anywhere in physical - memory - Bits 4-63: Reserved. - -- When image_size is zero, a bootloader should attempt to keep as much - memory as possible free for use by the kernel immediately after the - end of the kernel image. The amount of space required will vary - depending on selected features, and is effectively unbound. - -The Image must be placed text_offset bytes from a 2MB aligned base -address anywhere in usable system RAM and called there. The region -between the 2 MB aligned base address and the start of the image has no -special significance to the kernel, and may be used for other purposes. -At least image_size bytes from the start of the image must be free for -use by the kernel. -NOTE: versions prior to v4.6 cannot make use of memory below the -physical offset of the Image so it is recommended that the Image be -placed as close as possible to the start of system RAM. - -If an initrd/initramfs is passed to the kernel at boot, it must reside -entirely within a 1 GB aligned physical memory window of up to 32 GB in -size that fully covers the kernel Image as well. - -Any memory described to the kernel (even that below the start of the -image) which is not marked as reserved from the kernel (e.g., with a -memreserve region in the device tree) will be considered as available to -the kernel. - -Before jumping into the kernel, the following conditions must be met: - -- Quiesce all DMA capable devices so that memory does not get - corrupted by bogus network packets or disk data.

In the presence of a system cache or other - coherent masters with caches enabled, this will typically require - cache maintenance by VA rather than set/way operations. - System caches which respect the architected cache maintenance by VA - operations must be configured and may be enabled. - System caches which do not respect architected cache maintenance by VA - operations (not recommended) must be configured and disabled. - -- Architected timers - CNTFRQ must be programmed with the timer frequency and CNTVOFF must - be programmed with a consistent value on all CPUs. If entering the - kernel at EL1, CNTHCTL_EL2 must have EL1PCTEN (bit 0) set where - available. - -- Coherency - All CPUs to be booted by the kernel must be part of the same coherency - domain on entry to the kernel.

For hardware produced by ARM, these +errata are broadly classified into the following categories: + + ========== ======================================================== + Category A A critical error without a viable workaround. + Category B A significant or critical error with an acceptable + workaround. + Category C A minor error that is not expected to occur under normal + operation. + ========== ======================================================== + +For more information, consult one of the "Software Developers Errata +Notice" documents available on infocenter.arm.com (registration +required). + +As far as Linux is concerned, Category B errata may require some special +treatment in the operating system. For example, avoiding a particular +sequence of code, or configuring the processor in a particular way. A +less common situation may require similar actions in order to declassify +a Category A erratum into a Category C erratum. These are collectively +known as "software workarounds" and are only required in the minority of +cases (e.g. those cases that both require a non-secure workaround *and* +can be triggered by Linux). + +For software workarounds that may adversely impact systems unaffected by +the erratum in question, a Kconfig entry is added under "Kernel +Features" -> "ARM errata workarounds via the alternatives framework". +These are enabled by default and patched in at runtime when an affected +CPU is detected. For less-intrusive workarounds, a Kconfig option is not +available and the code is structured (preferably with a comment) in such +a way that the erratum will not be hit. + +This approach can make it slightly onerous to determine exactly which +errata are worked around in an arbitrary kernel source tree, so this +file acts as a registry of software workarounds in the Linux Kernel and +will be updated when new workarounds are committed and backported to +stable kernels. + ++----------------+-----------------+-----------------+-----------------------------+ +| Implementor | Component |

Software Workarounds - ======================================= - -Author: Will Deacon -Date : 27 November 2015 - -It is an unfortunate fact of life that hardware is often produced with -so-called "errata", which can cause it to deviate from the architecture -under specific circumstances. For hardware produced by ARM, these -errata are broadly classified into the following categories: - - Category A: A critical error without a viable workaround. - Category B: A significant or critical error with an acceptable - workaround. - Category C: A minor error that is not expected to occur under normal - operation. - -For more information, consult one of the "Software Developers Errata -Notice" documents available on infocenter.arm.com (registration -required). - -As far as Linux is concerned, Category B errata may require some special -treatment in the operating system. For example, avoiding a particular -sequence of code, or configuring the processor in a particular way. A -less common situation may require similar actions in order to declassify -a Category A erratum into a Category C erratum. These are collectively -known as "software workarounds" and are only required in the minority of -cases (e.g. those cases that both require a non-secure workaround *and* -can be triggered by Linux). - -For software workarounds that may adversely impact systems unaffected by -the erratum in question, a Kconfig entry is added under "Kernel -Features" -> "ARM errata workarounds via the alternatives framework". -These are enabled by default and patched in at runtime when an affected -CPU is detected. For less-intrusive workarounds, a Kconfig option is not -available and the code is structured (preferably with a comment) in such -a way that the erratum will not be hit. - -This approach can make it slightly onerous to determine exactly which -errata are worked around in an arbitrary kernel source tree, so this -file acts as a registry of software workarounds in the Linux Kernel and -will be updated when new workarounds are committed and backported to -stable kernels. - -| Implementor | Component | Erratum ID | Kconfig | -+----------------+-----------------+-----------------+-----------------------------+ -| Allwinner | A64/R18 | UNKNOWN1 | SUN50I_ERRATUM_UNKNOWN1 | -| | | | | -| ARM | Cortex-A53 | #826319 | ARM64_ERRATUM_826319 | -| ARM | Cortex-A53 | #827319 | ARM64_ERRATUM_827319 | -| ARM | Cortex-A53 | #824069 | ARM64_ERRATUM_824069 | -| ARM | Cortex-A53 | #819472 | ARM64_ERRATUM_819472 | -| ARM | Cortex-A53 | #845719 | ARM64_ERRATUM_845719 | -| ARM | Cortex-A53 | #843419 | ARM64_ERRATUM_843419 | -| ARM | Cortex-A57 | #832075 | ARM64_ERRATUM_832075 | -| ARM | Cortex-A57 | #852523 | N/A | -| ARM | Cortex-A57 | #834220 | ARM64_ERRATUM_834220 | -| ARM | Cortex-A72 | #853709 | N/A | -| ARM | Cortex-A73 | #858921 | ARM64_ERRATUM_858921 | -| ARM | Cortex-A55 | #1024718 | ARM64_ERRATUM_1024718 | -| ARM | Cortex-A76 | #1188873,1418040| ARM64_ERRATUM_1418040 | -| ARM | Cortex-A76 | #1165522 | ARM64_ERRATUM_1165522 | -| ARM | Cortex-A76 | #1286807 | ARM64_ERRATUM_1286807 | -| ARM | Cortex-A76 | #1463225 | ARM64_ERRATUM_1463225 | -| ARM | Neoverse-N1 | #1188873,1418040| ARM64_ERRATUM_1418040 | -| ARM | MMU-500 | #841119,826419 | N/A | -| | | | | -| Cavium | ThunderX ITS | #22375,24313 | CAVIUM_ERRATUM_22375 | -| Cavium | ThunderX ITS | #23144 | CAVIUM_ERRATUM_23144 | -| Cavium | ThunderX GICv3 | #23154 | CAVIUM_ERRATUM_23154 | -| Cavium | ThunderX Core | #27456 | CAVIUM_ERRATUM_27456 | -| Cavium | ThunderX Core | #30115 | CAVIUM_ERRATUM_30115 | -| Cavium | ThunderX SMMUv2 | #27704 | N/A | -| Cavium | ThunderX2 SMMUv3| #74 | N/A | -| Cavium | ThunderX2 SMMUv3| #126 | N/A | -| | | | | -| Freescale/NXP | LS2080A/LS1043A | A-008585 | FSL_ERRATUM_A008585 | -| | | | | -| Hisilicon | Hip0{5,6,7} | #161010101 | HISILICON_ERRATUM_161010101 | -| Hisilicon | Hip0{6,7} | #161010701 | N/A | -| Hisilicon | Hip07 | #161600802 | HISILICON_ERRATUM_161600802 | -| Hisilicon | Hip08 SMMU PMCG | #162001800 | N/A | -| | | | | -| Qualcomm Tech. | Kryo/Falkor v1 | E1003 | QCOM_FALKOR_ERRATUM_1003 | -| Qualcomm Tech. | Falkor v1 | E1009 | QCOM_FALKOR_ERRATUM_1009 | -| Qualcomm Tech. | QDF2400 ITS | E0065 | QCOM_QDF2400_ERRATUM_0065 | -| Qualcomm Tech. | Falkor v{1,2} | E1041 | QCOM_FALKOR_ERRATUM_1041 | -| Fujitsu | A64FX | E#010001 | FUJITSU_ERRATUM_010001 | diff --git a/Documentation/arm64/sve.rst b/Documentation/arm64/sve.rst new file mode 100644 index 000000000000..38422ab249dd --- /dev/null +++ b/Documentation/arm64/sve.rst @@ -0,0 +1,529 @@ +=================================================== +Scalable Vector Extension support for AArch64 Linux +=================================================== + +Author: Dave Martin + +Date: 4 August 2017 + +This document outlines briefly the interface provided to userspace by Linux in +order to support use of the ARM Scalable Vector Extension (SVE). + +This is an outline of the most important features and issues only and not +intended to be exhaustive. + +This document does not aim to describe the SVE architecture or programmer's +model. To aid understanding, a minimal description of relevant programmer's +model features for SVE is included in Appendix A. + + +1. General +----------- + +* SVE registers Z0..Z31, P0..P15 and FFR and the current vector length VL, are + tracked per-thread. + +* The presence of SVE is reported to userspace via HWCAP_SVE in the aux vector + AT_HWCAP entry. Presence of this flag implies the presence of the SVE + instructions and registers, and the Linux-specific system interfaces + described in this document. SVE is reported in /proc/cpuinfo as "sve". + +* Support for the execution of SVE instructions in userspace can also be + detected by reading the CPU ID register ID_AA64PFR0_EL1 using an MRS + instruction, and checking that the value of the SVE field is nonzero. [3] + + It does not guarantee the presence of the system interfaces described in the + following sections: software that needs to verify that those interfaces are + present must check for HWCAP_SVE instead. + +* On hardware that supports the SVE2 extensions, HWCAP2_SVE2 will also + be reported in the AT_HWCAP2 aux vector entry. In addition to this, + optional extensions to SVE2 may be reported by the presence of: + + HWCAP2_SVE2 + HWCAP2_SVEAES + HWCAP2_SVEPMULL + HWCAP2_SVEBITPERM + HWCAP2_SVESHA3 + HWCAP2_SVESM4 + + This list may be extended over time as the SVE architecture evolves. + + These extensions are also reported via the CPU ID register ID_AA64ZFR0_EL1, + which userspace can read using an MRS instruction. See elf_hwcaps.txt and + cpu-feature-registers.txt for details. + +* Debuggers should restrict themselves to interacting with the target via the + NT_ARM_SVE regset. The recommended way of detecting support for this regset + is to connect to a target process first and then attempt a + ptrace(PTRACE_GETREGSET, pid, NT_ARM_SVE, &iov). + + +2. Vector length terminology +----------------------------- + +The size of an SVE vector (Z) register is referred to as the "vector length". + +To avoid confusion about the units used to express vector length, the kernel +adopts the following conventions: + +* Vector length (VL) = size of a Z-register in bytes + +* Vector quadwords (VQ) = size of a Z-register in units of 128 bits + +(So, VL = 16 * VQ.) + +The VQ convention is used where the underlying granularity is important, such +as in data structure definitions. In most other situations, the VL convention +is used. This is consistent with the meaning of the "VL" pseudo-register in +the SVE instruction set architecture. + + +3. System call behaviour +------------------------- + +* On syscall, V0..V31 are preserved (as without SVE). Thus, bits [127:0] of + Z0..Z31 are preserved. All other bits of Z0..Z31, and all of P0..P15 and FFR + become unspecified on return from a syscall. + +* The SVE registers are not used to pass arguments to or receive results from + any syscall. + +* In practice the affected registers/bits will be preserved or will be replaced + with zeros on return from a syscall, but userspace should not make + assumptions about this. The kernel behaviour may vary on a case-by-case + basis. + +* All other SVE state of a thread, including the currently configured vector + length, the state of the PR_SVE_VL_INHERIT flag, and the deferred vector + length (if any), is preserved across all syscalls, subject to the specific + exceptions for execve() described in section 6. + + In particular, on return from a fork() or clone(), the parent and new child + process or thread share identical SVE configuration, matching that of the + parent before the call. + + +4. Signal handling +------------------- + +* A new signal frame record sve_context encodes the SVE registers on signal + delivery. [1] + +* This record is supplementary to fpsimd_context. The FPSR and FPCR registers + are only present in fpsimd_context. For convenience, the content of V0..V31 + is duplicated between sve_context and fpsimd_context. + +* The signal frame record for SVE always contains basic metadata, in particular + the thread's vector length (in sve_context.vl). + +* The SVE registers may or may not be included in the record, depending on + whether the registers are live for the thread. The registers are present if + and only if: + sve_context.head.size >= SVE_SIG_CONTEXT_SIZE(sve_vq_from_vl(sve_context.vl)). + +* If the registers are present, the remainder of the record has a vl-dependent + size and layout. Macros SVE_SIG_* are defined [1] to facilitate access to + the members. + +* If the SVE context is too big to fit in sigcontext.__reserved[], then extra + space is allocated on the stack, an extra_context record is written in + __reserved[] referencing this space. sve_context is then written in the + extra space. Refer to [1] for further details about this mechanism. + + +5. Signal return +----------------- + +When returning from a signal handler: + +* If there is no sve_context record in the signal frame, or if the record is + present but contains no register data as desribed in the previous section, + then the SVE registers/bits become non-live and take unspecified values. + +* If sve_context is present in the signal frame and contains full register + data, the SVE registers become live and are populated with the specified + data. However, for backward compatibility reasons, bits [127:0] of Z0..Z31 + are always restored from the corresponding members of fpsimd_context.vregs[] + and not from sve_context. The remaining bits are restored from sve_context. + +* Inclusion of fpsimd_context in the signal frame remains mandatory, + irrespective of whether sve_context is present or not. + +* The vector length cannot be changed via signal return. If sve_context.vl in + the signal frame does not match the current vector length, the signal return + attempt is treated as illegal, resulting in a forced SIGSEGV. + + +6. prctl extensions +-------------------- + +Some new prctl() calls are added to allow programs to manage the SVE vector +length: + +prctl(PR_SVE_SET_VL, unsigned long arg) + + Sets the vector length of the calling thread and related flags, where + arg == vl | flags. Other threads of the calling process are unaffected. + + vl is the desired vector length, where sve_vl_valid(vl) must be true. + + flags: + + PR_SVE_SET_VL_INHERIT + + Inherit the current vector length across execve(). Otherwise, the + vector length is reset to the system default at execve(). (See + Section 9.) + + PR_SVE_SET_VL_ONEXEC + + Defer the requested vector length change until the next execve() + performed by this thread. + + The effect is equivalent to implicit exceution of the following + call immediately after the next execve() (if any) by the thread: + + prctl(PR_SVE_SET_VL, arg & ~PR_SVE_SET_VL_ONEXEC) + + This allows launching of a new program with a different vector + length, while avoiding runtime side effects in the caller. + + + Without PR_SVE_SET_VL_ONEXEC, the requested change takes effect + immediately. + + + Return value: a nonnegative on success, or a negative value on error: + EINVAL: SVE not supported, invalid vector length requested, or + invalid flags. + + + On success: + + * Either the calling thread's vector length or the deferred vector length + to be applied at the next execve() by the thread (dependent on whether + PR_SVE_SET_VL_ONEXEC is present in arg), is set to the largest value + supported by the system that is less than or equal to vl. If vl == + SVE_VL_MAX, the value set will be the largest value supported by the + system. + + * Any previously outstanding deferred vector length change in the calling + thread is cancelled. + + * The returned value describes the resulting configuration, encoded as for + PR_SVE_GET_VL. The vector length reported in this value is the new + current vector length for this thread if PR_SVE_SET_VL_ONEXEC was not + present in arg; otherwise, the reported vector length is the deferred + vector length that will be applied at the next execve() by the calling + thread. + + * Changing the vector length causes all of P0..P15, FFR and all bits of + Z0..Z31 except for Z0 bits [127:0] .. Z31 bits [127:0] to become + unspecified. Calling PR_SVE_SET_VL with vl equal to the thread's current + vector length, or calling PR_SVE_SET_VL with the PR_SVE_SET_VL_ONEXEC + flag, does not constitute a change to the vector length for this purpose. + + +prctl(PR_SVE_GET_VL) + + Gets the vector length of the calling thread. + + The following flag may be OR-ed into the result: + + PR_SVE_SET_VL_INHERIT + + Vector length will be inherited across execve(). + + There is no way to determine whether there is an outstanding deferred + vector length change (which would only normally be the case between a + fork() or vfork() and the corresponding execve() in typical use). + + To extract the vector length from the result, and it with + PR_SVE_VL_LEN_MASK. + + Return value: a nonnegative value on success, or a negative value on error: + EINVAL: SVE not supported. + + +7. ptrace extensions +--------------------- + +* A new regset NT_ARM_SVE is defined for use with PTRACE_GETREGSET and + PTRACE_SETREGSET. + + Refer to [2] for definitions. + +The regset data starts with struct user_sve_header, containing: + + size + + Size of the complete regset, in bytes. + This depends on vl and possibly on other things in the future. + + If a call to PTRACE_GETREGSET requests less data than the value of + size, the caller can allocate a larger buffer and retry in order to + read the complete regset. + + max_size + + Maximum size in bytes that the regset can grow to for the target + thread. The regset won't grow bigger than this even if the target + thread changes its vector length etc. + + vl + + Target thread's current vector length, in bytes. + + max_vl + + Maximum possible vector length for the target thread. + + flags + + either + + SVE_PT_REGS_FPSIMD + + SVE registers are not live (GETREGSET) or are to be made + non-live (SETREGSET). + + The payload is of type struct user_fpsimd_state, with the same + meaning as for NT_PRFPREG, starting at offset + SVE_PT_FPSIMD_OFFSET from the start of user_sve_header. + + Extra data might be appended in the future: the size of the + payload should be obtained using SVE_PT_FPSIMD_SIZE(vq, flags). + + vq should be obtained using sve_vq_from_vl(vl). + + or + + SVE_PT_REGS_SVE + + SVE registers are live (GETREGSET) or are to be made live + (SETREGSET). + + The payload contains the SVE register data, starting at offset + SVE_PT_SVE_OFFSET from the start of user_sve_header, and with + size SVE_PT_SVE_SIZE(vq, flags); + + ... OR-ed with zero or more of the following flags, which have the same + meaning and behaviour as the corresponding PR_SET_VL_* flags: + + SVE_PT_VL_INHERIT + + SVE_PT_VL_ONEXEC (SETREGSET only). + +* The effects of changing the vector length and/or flags are equivalent to + those documented for PR_SVE_SET_VL. + + The caller must make a further GETREGSET call if it needs to know what VL is + actually set by SETREGSET, unless is it known in advance that the requested + VL is supported. + +* In the SVE_PT_REGS_SVE case, the size and layout of the payload depends on + the header fields. The SVE_PT_SVE_*() macros are provided to facilitate + access to the members. + +* In either case, for SETREGSET it is permissible to omit the payload, in which + case only the vector length and flags are changed (along with any + consequences of those changes). + +* For SETREGSET, if an SVE_PT_REGS_SVE payload is present and the + requested VL is not supported, the effect will be the same as if the + payload were omitted, except that an EIO error is reported. No + attempt is made to translate the payload data to the correct layout + for the vector length actually set. The thread's FPSIMD state is + preserved, but the remaining bits of the SVE registers become + unspecified. It is up to the caller to translate the payload layout + for the actual VL and retry. + +* The effect of writing a partial, incomplete payload is unspecified. + + +8. ELF coredump extensions +--------------------------- + +* A NT_ARM_SVE note will be added to each coredump for each thread of the + dumped process. The contents will be equivalent to the data that would have + been read if a PTRACE_GETREGSET of NT_ARM_SVE were executed for each thread + when the coredump was generated. + + +9. System runtime configuration +-------------------------------- + +* To mitigate the ABI impact of expansion of the signal frame, a policy + mechanism is provided for administrators, distro maintainers and developers + to set the default vector length for userspace processes: + +/proc/sys/abi/sve_default_vector_length + + Writing the text representation of an integer to this file sets the system + default vector length to the specified value, unless the value is greater + than the maximum vector length supported by the system in which case the + default vector length is set to that maximum. + + The result can be determined by reopening the file and reading its + contents. + + At boot, the default vector length is initially set to 64 or the maximum + supported vector length, whichever is smaller. This determines the initial + vector length of the init process (PID 1). + + Reading this file returns the current system default vector length. + +* At every execve() call, the new vector length of the new process is set to + the system default vector length, unless + + * PR_SVE_SET_VL_INHERIT (or equivalently SVE_PT_VL_INHERIT) is set for the + calling thread, or + + * a deferred vector length change is pending, established via the + PR_SVE_SET_VL_ONEXEC flag (or SVE_PT_VL_ONEXEC). + +* Modifying the system default vector length does not affect the vector length + of any existing process or thread that does not make an execve() call. + + +Appendix A. SVE programmer's model (informative) +================================================= + +This section provides a minimal description of the additions made by SVE to the +ARMv8-A programmer's model that are relevant to this document. + +Note: This section is for information only and not intended to be complete or +to replace any architectural specification. + +A.1.

For convenience, the content of V0..V31 - is duplicated between sve_context and fpsimd_context. - -* The signal frame record for SVE always contains basic metadata, in particular - the thread's vector length (in sve_context.vl). - -* The SVE registers may or may not be included in the record, depending on - whether the registers are live for the thread. The registers are present if - and only if: - sve_context.head.size >= SVE_SIG_CONTEXT_SIZE(sve_vq_from_vl(sve_context.vl)). - -* If the registers are present, the remainder of the record has a vl-dependent - size and layout. Macros SVE_SIG_* are defined [1] to facilitate access to - the members. - -* If the SVE context is too big to fit in sigcontext.__reserved[], then extra - space is allocated on the stack, an extra_context record is written in - __reserved[] referencing this space. sve_context is then written in the - extra space. Refer to [1] for further details about this mechanism. - - -5. Signal return ------------------ - -When returning from a signal handler: - -* If there is no sve_context record in the signal frame, or if the record is - present but contains no register data as desribed in the previous section, - then the SVE registers/bits become non-live and take unspecified values. - -* If sve_context is present in the signal frame and contains full register - data, the SVE registers become live and are populated with the specified - data. However, for backward compatibility reasons, bits [127:0] of Z0..Z31 - are always restored from the corresponding members of fpsimd_context.vregs[] - and not from sve_context. The remaining bits are restored from sve_context. - -* Inclusion of fpsimd_context in the signal frame remains mandatory, - irrespective of whether sve_context is present or not. - -* The vector length cannot be changed via signal return. If sve_context.vl in - the signal frame does not match the current vector length, the signal return - attempt is treated as illegal, resulting in a forced SIGSEGV. - - -6. prctl extensions --------------------- - -Some new prctl() calls are added to allow programs to manage the SVE vector -length: - -prctl(PR_SVE_SET_VL, unsigned long arg) - - Sets the vector length of the calling thread and related flags, where - arg == vl | flags. Other threads of the calling process are unaffected. - - vl is the desired vector length, where sve_vl_valid(vl) must be true. - - flags: - - PR_SVE_SET_VL_INHERIT - - Inherit the current vector length across execve(). Otherwise, the - vector length is reset to the system default at execve(). (See - Section 9.) - - PR_SVE_SET_VL_ONEXEC - - Defer the requested vector length change until the next execve() - performed by this thread. - - The effect is equivalent to implicit exceution of the following - call immediately after the next execve() (if any) by the thread: - - prctl(PR_SVE_SET_VL, arg & ~PR_SVE_SET_VL_ONEXEC) - - This allows launching of a new program with a different vector - length, while avoiding runtime side effects in the caller. - - - Without PR_SVE_SET_VL_ONEXEC, the requested change takes effect - immediately. - - - Return value: a nonnegative on success, or a negative value on error: - EINVAL: SVE not supported, invalid vector length requested, or - invalid flags. - - - On success: - - * Either the calling thread's vector length or the deferred vector length - to be applied at the next execve() by the thread (dependent on whether - PR_SVE_SET_VL_ONEXEC is present in arg), is set to the largest value - supported by the system that is less than or equal to vl. If vl == - SVE_VL_MAX, the value set will be the largest value supported by the - system. - - * Any previously outstanding deferred vector length change in the calling - thread is cancelled. - - * The returned value describes the resulting configuration, encoded as for - PR_SVE_GET_VL. The vector length reported in this value is the new - current vector length for this thread if PR_SVE_SET_VL_ONEXEC was not - present in arg; otherwise, the reported vector length is the deferred - vector length that will be applied at the next execve() by the calling - thread. - - * Changing the vector length causes all of P0..P15, FFR and all bits of - Z0..Z31 except for Z0 bits [127:0] .. Z31 bits [127:0] to become - unspecified. Calling PR_SVE_SET_VL with vl equal to the thread's current - vector length, or calling PR_SVE_SET_VL with the PR_SVE_SET_VL_ONEXEC - flag, does not constitute a change to the vector length for this purpose. - - -prctl(PR_SVE_GET_VL) - - Gets the vector length of the calling thread. - - The following flag may be OR-ed into the result: - - PR_SVE_SET_VL_INHERIT - - Vector length will be inherited across execve(). - - There is no way to determine whether there is an outstanding deferred - vector length change (which would only normally be the case between a - fork() or vfork() and the corresponding execve() in typical use). - - To extract the vector length from the result, and it with - PR_SVE_VL_LEN_MASK. - - Return value: a nonnegative value on success, or a negative value on error: - EINVAL: SVE not supported. - - -7. ptrace extensions ---------------------- - -* A new regset NT_ARM_SVE is defined for use with PTRACE_GETREGSET and - PTRACE_SETREGSET. - - Refer to [2] for definitions. - -The regset data starts with struct user_sve_header, containing: - - size - - Size of the complete regset, in bytes. - This depends on vl and possibly on other things in the future. - - If a call to PTRACE_GETREGSET requests less data than the value of - size, the caller can allocate a larger buffer and retry in order to - read the complete regset. - - max_size - - Maximum size in bytes that the regset can grow to for the target - thread. The regset won't grow bigger than this even if the target - thread changes its vector length etc. - - vl - - Target thread's current vector length, in bytes. - - max_vl - - Maximum possible vector length for the target thread. - - flags - - either - - SVE_PT_REGS_FPSIMD - - SVE registers are not live (GETREGSET) or are to be made - non-live (SETREGSET). - - The payload is of type struct user_fpsimd_state, with the same - meaning as for NT_PRFPREG, starting at offset - SVE_PT_FPSIMD_OFFSET from the start of user_sve_header. - - Extra data might be appended in the future: the size of the - payload should be obtained using SVE_PT_FPSIMD_SIZE(vq, flags). - - vq should be obtained using sve_vq_from_vl(vl). - - or - - SVE_PT_REGS_SVE - - SVE registers are live (GETREGSET) or are to be made live - (SETREGSET). - - The payload contains the SVE register data, starting at offset - SVE_PT_SVE_OFFSET from the start of user_sve_header, and with - size SVE_PT_SVE_SIZE(vq, flags); - - ... OR-ed with zero or more of the following flags, which have the same - meaning and behaviour as the corresponding PR_SET_VL_* flags: - - SVE_PT_VL_INHERIT - - SVE_PT_VL_ONEXEC (SETREGSET only). - -* The effects of changing the vector length and/or flags are equivalent to - those documented for PR_SVE_SET_VL. - - The caller must make a further GETREGSET call if it needs to know what VL is - actually set by SETREGSET, unless is it known in advance that the requested - VL is supported. - -* In the SVE_PT_REGS_SVE case, the size and layout of the payload depends on - the header fields. The SVE_PT_SVE_*() macros are provided to facilitate - access to the members. - -* In either case, for SETREGSET it is permissible to omit the payload, in which - case only the vector length and flags are changed (along with any - consequences of those changes). - -* For SETREGSET, if an SVE_PT_REGS_SVE payload is present and the - requested VL is not supported, the effect will be the same as if the - payload were omitted, except that an EIO error is reported. No - attempt is made to translate the payload data to the correct layout - for the vector length actually set. The thread's FPSIMD state is - preserved, but the remaining bits of the SVE registers become - unspecified. It is up to the caller to translate the payload layout - for the actual VL and retry. - -* The effect of writing a partial, incomplete payload is unspecified. - - -8. ELF coredump extensions ---------------------------- - -* A NT_ARM_SVE note will be added to each coredump for each thread of the - dumped process. The contents will be equivalent to the data that would have - been read if a PTRACE_GETREGSET of NT_ARM_SVE were executed for each thread - when the coredump was generated. - - -9. System runtime configuration --------------------------------- - -* To mitigate the ABI impact of expansion of the signal frame, a policy - mechanism is provided for administrators, distro maintainers and developers - to set the default vector length for userspace processes: - -/proc/sys/abi/sve_default_vector_length - - Writing the text representation of an integer to this file sets the system - default vector length to the specified value, unless the value is greater - than the maximum vector length supported by the system in which case the - default vector length is set to that maximum. - - The result can be determined by reopening the file and reading its - contents. - - At boot, the default vector length is initially set to 64 or the maximum - supported vector length, whichever is smaller. This determines the initial - vector length of the init process (PID 1). - - Reading this file returns the current system default vector length. - -* At every execve() call, the new vector length of the new process is set to - the system default vector length, unless - - * PR_SVE_SET_VL_INHERIT (or equivalently SVE_PT_VL_INHERIT) is set for the - calling thread, or - - * a deferred vector length change is pending, established via the - PR_SVE_SET_VL_ONEXEC flag (or SVE_PT_VL_ONEXEC). - -* Modifying the system default vector length does not affect the vector length - of any existing process or thread that does not make an execve() call. - - -Appendix A. SVE programmer's model (informative) -================================================= - -This section provides a minimal description of the additions made by SVE to the -ARMv8-A programmer's model that are relevant to this document. - -Note: This section is for information only and not intended to be complete or -to replace any architectural specification. - -A.1. Registers ---------------- - -In A64 state, SVE adds the following: - -* 32 8VL-bit vector registers Z0..Z31 - For each Zn, Zn bits [127:0] alias the ARMv8-A vector register Vn. - - A register write using a Vn register name zeros all bits of the corresponding - Zn except for bits [127:0]. - -* 16 VL-bit predicate registers P0..P15 - -* 1 VL-bit special-purpose predicate register FFR (the "first-fault register") - -* a VL "pseudo-register" that determines the size of each vector register - - The SVE instruction set architecture provides no way to write VL directly. - Instead, it can be modified only by EL1 and above, by writing appropriate - system registers. - -* The value of VL can be configured at runtime by EL1 and above: - 16 <= VL <= VLmax, where VL must be a multiple of 16. - -* The maximum vector length is determined by the hardware: - 16 <= VLmax <= 256. - - (The SVE architecture specifies 256, but permits future architecture - revisions to raise this limit.) - -* FPSR and FPCR are retained from ARMv8-A, and interact with SVE floating-point - operations in a similar way to the way in which they interact with ARMv8 - floating-point operations. - - 8VL-1 128 0 bit index - +---- //// -----------------+ - Z0 | : V0 | - : : - Z7 | : V7 | - Z8 | : * V8 | - : : : - Z15 | : *V15 | - Z16 | : V16 | - : : - Z31 | : V31 | - +---- //// -----------------+ - 31 0 - VL-1 0 +-------+ - +---- //// --+ FPSR | | - P0 | | +-------+ - : | | *FPCR | | - P15 | | +-------+ - +---- //// --+ - FFR | | +-----+ - +---- //// --+ VL | | - +-----+ - -(*) callee-save: - This only applies to bits [63:0] of Z-/V-registers. - FPCR contains callee-save and caller-save bits.

Many folks have had -"trouble" with cdroms because of this requirement, so the driver now probes -for both units, though success is more likely when the drive is jumpered -correctly. - -Courtesy of Scott Snyder and others, the driver supports ATAPI cdrom drives -such as the NEC-260 and the new MITSUMI triple/quad speed drives. -Such drives will be identified at boot time, just like a hard disk. - -If for some reason your cdrom drive is *not* found at boot time, you can force -the probe to look harder by supplying a kernel command line parameter -via LILO, such as: - - ide_core.cdrom=1.0 /* "master" on second interface (hdc) */ -or - ide_core.cdrom=1.1 /* "slave" on second interface (hdd) */ - -For example, a GW2000 system might have a hard drive on the primary -interface (/dev/hda) and an IDE cdrom drive on the secondary interface -(/dev/hdc). To mount a CD in the cdrom drive, one would use something like: - - ln -sf /dev/hdc /dev/cdrom - mkdir /mnt/cdrom - mount /dev/cdrom /mnt/cdrom -t iso9660 -o ro - -If, after doing all of the above, mount doesn't work and you see -errors from the driver (with dmesg) complaining about `status=0xff', -this means that the hardware is not responding to the driver's attempts -to read it. One of the following is probably the problem: - - - Your hardware is broken. - - - You are using the wrong address for the device, or you have the - drive jumpered wrong. Review the configuration instructions above. - - - Your IDE controller requires some nonstandard initialization sequence - before it will work properly. If this is the case, there will often - be a separate MS-DOS driver just for the controller. IDE interfaces - on sound cards usually fall into this category. Such configurations - can often be made to work by first booting MS-DOS, loading the - appropriate drivers, and then warm-booting linux (without powering - off). This can be automated using loadlin in the MS-DOS autoexec. - -If you always get timeout errors, interrupts from the drive are probably -not making it to the host. Check how you have the hardware jumpered -and make sure it matches what the driver expects (see the configuration -instructions above). If you have a PCI system, also check the BIOS -setup; I've had one report of a system which was shipped with IRQ 15 -disabled by the BIOS. - -The kernel is able to execute binaries directly off of the cdrom, -provided it is mounted with the default block size of 1024 (as above). - -Please pass on any feedback on any of this stuff to the maintainer, -whose address can be found in linux/MAINTAINERS. - -The IDE driver is modularized. The high level disk/CD-ROM/tape/floppy -drivers can always be compiled as loadable modules, the chipset drivers -can only be compiled into the kernel, and the core code (ide.c) can be -compiled as a loadable module provided no chipset support is needed. - -When using ide.c as a module in combination with kmod, add: - - alias block-major-3 ide-probe - -to a configuration file in /etc/modprobe.d/. - -When ide.c is used as a module, you can pass command line parameters to the -driver using the "options=" keyword to insmod, while replacing any ',' with -';'. - - -================================================================================ - -Summary of ide driver parameters for kernel command line --------------------------------------------------------- - -For legacy IDE VLB host drivers (ali14xx/dtc2278/ht6560b/qd65xx/umc8672) -you need to explicitly enable probing by using "probe" kernel parameter, -i.e. to enable probing for ALI M14xx chipsets (ali14xx host driver) use: - -* "ali14xx.probe" boot option when ali14xx driver is built-in the kernel - -* "probe" module parameter when ali14xx driver is compiled as module - ("modprobe ali14xx probe") - -Also for legacy CMD640 host driver (cmd640) you need to use "probe_vlb" -kernel paremeter to enable probing for VLB version of the chipset (PCI ones -are detected automatically). - -You also need to use "probe" kernel parameter for ide-4drives driver -(support for IDE generic chipset with four drives on one port). - -To enable support for IDE doublers on Amiga use "doubler" kernel parameter -for gayle host driver (i.e. "gayle.doubler" if the driver is built-in). - -To force ignoring cable detection (this should be needed only if you're using -short 40-wires cable which cannot be automatically detected - if this is not -a case please report it as a bug instead) use "ignore_cable" kernel parameter: - -* "ide_core.ignore_cable=[interface_number]" boot option if IDE is built-in - (i.e. "ide_core.ignore_cable=1" to force ignoring cable for "ide1") - -* "ignore_cable=[interface_number]" module parameter (for ide_core module) - if IDE is compiled as module - -Other kernel parameters for ide_core are: - -* "nodma=[interface_number.device_number]" to disallow DMA for a device - -* "noflush=[interface_number.device_number]" to disable flush requests - -* "nohpa=[interface_number.device_number]" to disable Host Protected Area - -* "noprobe=[interface_number.device_number]" to skip probing - -* "nowerr=[interface_number.device_number]" to ignore the WRERR_STAT bit - -* "cdrom=[interface_number.device_number]" to force device as a CD-ROM - -* "chs=[interface_number.device_number]" to force device as a disk (using CHS) - -================================================================================ - -Some Terminology ----------------- -IDE = Integrated Drive Electronics, meaning that each drive has a built-in -controller, which is why an "IDE interface card" is not a "controller card". - -ATA = AT (the old IBM 286 computer) Attachment Interface, a draft American -National Standard for connecting hard drives to PCs.

Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

"config" starts a new config entry. The following lines +define attributes for this config option. Attributes can be the type of +the config option, input prompt, dependencies, help text and default +values. A config option can be defined multiple times with the same +name, but every definition can have only a single input prompt and the +type must not conflict. + +Menu attributes +--------------- + +A menu entry can have a number of attributes. Not all of them are +applicable everywhere (see syntax). + +- type definition: "bool"/"tristate"/"string"/"hex"/"int" + Every config option must have a type. There are only two basic types: + tristate and string; the other types are based on these two. The type + definition optionally accepts an input prompt, so these two examples + are equivalent:: + + bool "Networking support" + + and:: + + bool + prompt "Networking support" + +- input prompt: "prompt" ["if" ] + Every menu entry can have at most one prompt, which is used to display + to the user. Optionally dependencies only for this prompt can be added + with "if". + +- default value: "default" ["if" ] + A config option can have any number of default values. If multiple + default values are visible, only the first defined one is active. + Default values are not limited to the menu entry where they are + defined. This means the default can be defined somewhere else or be + overridden by an earlier definition. + The default value is only assigned to the config symbol if no other + value was set by the user (via the input prompt above). If an input + prompt is visible the default value is presented to the user and can + be overridden by him. + Optionally, dependencies only for this default value can be added with + "if". + + The default value deliberately defaults to 'n' in order to avoid bloating the + build. With few exceptions, new config options should not change this. The + intent is for "make oldconfig" to add as little as possible to the config from + release to release. + + Note: + Things that merit "default y/m" include: + + a) A new Kconfig option for something that used to always be built + should be "default y". + + b) A new gatekeeping Kconfig option that hides/shows other Kconfig + options (but does not generate any code of its own), should be + "default y" so people will see those other options. + + c) Sub-driver behavior or similar options for a driver that is + "default n". This allows you to provide sane defaults. + + d) Hardware or infrastructure that everybody expects, such as CONFIG_NET + or CONFIG_BLOCK. These are rare exceptions. + +- type definition + default value:: + + "def_bool"/"def_tristate" ["if" ] + + This is a shorthand notation for a type definition plus a value. + Optionally dependencies for this default value can be added with "if". + +- dependencies: "depends on" + This defines a dependency for this menu entry. If multiple + dependencies are defined, they are connected with '&&'. Dependencies + are applied to all other options within this menu entry (which also + accept an "if" expression), so these two examples are equivalent:: + + bool "foo" if BAR + default y if BAR + + and:: + + depends on BAR + bool "foo" + default y + +- reverse dependencies: "select" ["if" ] + While normal dependencies reduce the upper limit of a symbol (see + below), reverse dependencies can be used to force a lower limit of + another symbol. The value of the current menu symbol is used as the + minimal value can be set to. If is selected multiple + times, the limit is set to the largest selection. + Reverse dependencies can only be used with boolean or tristate + symbols. + + Note: + select should be used with care. select will force + a symbol to a value without visiting the dependencies. + By abusing select you are able to select a symbol FOO even + if FOO depends on BAR that is not set. + In general use select only for non-visible symbols + (no prompts anywhere) and for symbols with no dependencies. + That will limit the usefulness but on the other hand avoid + the illegal configurations all over. + +- weak reverse dependencies: "imply" ["if" ] + This is similar to "select" as it enforces a lower limit on another + symbol except that the "implied" symbol's value may still be set to n + from a direct dependency or with a visible prompt. + + Given the following example:: + + config FOO + tristate + imply BAZ + + config BAZ + tristate + depends on BAR + + The following values are possible: + + === === ============= ============== + FOO BAR BAZ's default choice for BAZ + === === ============= ============== + n y n N/m/y + m y m M/y/n + y y y Y/n + y n * N + === === ============= ============== + + This is useful e.g. with multiple drivers that want to indicate their + ability to hook into a secondary subsystem while allowing the user to + configure that subsystem out without also having to unset these drivers. + +- limiting menu display: "visible if" + This attribute is only applicable to menu blocks, if the condition is + false, the menu block is not displayed to the user (the symbols + contained there can still be selected by other symbols, though). It is + similar to a conditional "prompt" attribute for individual menu + entries. Default value of "visible" is true. + +- numerical ranges: "range" ["if" ] + This allows to limit the range of possible input values for int + and hex symbols. The user can only input a value which is larger than + or equal to the first symbol and smaller than or equal to the second + symbol. + +- help text: "help" or "---help---" + This defines a help text. The end of the help text is determined by + the indentation level, this means it ends at the first line which has + a smaller indentation than the first line of the help text. + "---help---" and "help" do not differ in behaviour, "---help---" is + used to help visually separate configuration logic from help within + the file as an aid to developers. + +- misc options: "option" [=] + Various less common options can be defined via this option syntax, + which can modify the behaviour of the menu entry and its config + symbol. These options are currently possible: + + - "defconfig_list" + This declares a list of default entries which can be used when + looking for the default configuration (which is used when the main + .config doesn't exists yet.) + + - "modules" + This declares the symbol to be used as the MODULES symbol, which + enables the third modular state for all config symbols. + At most one symbol may have the "modules" option set. + + - "allnoconfig_y" + This declares the symbol as one that should have the value y when + using "allnoconfig". Used for symbols that hide other symbols. + +Menu dependencies +----------------- + +Dependencies define the visibility of a menu entry and can also reduce +the input range of tristate symbols. The tristate logic used in the +expressions uses one more state than normal boolean logic to express the +module state. Dependency expressions have the following syntax:: + + ::= (1) + '=' (2) + '!=' (3) + '<' (4) + '>' (4) + '<=' (4) + '>=' (4) + '(' ')' (5) + '!' (6) + '&&' (7) + '||' (8) + +Expressions are listed in decreasing order of precedence. + +(1) Convert the symbol into an expression. Boolean and tristate symbols + are simply converted into the respective expression values. All + other symbol types result in 'n'. +(2) If the values of both symbols are equal, it returns 'y', + otherwise 'n'. +(3) If the values of both symbols are equal, it returns 'n', + otherwise 'y'. +(4) If value of is respectively lower, greater, lower-or-equal, + or greater-or-equal than value of , it returns 'y', + otherwise 'n'. +(5) Returns the value of the expression. Used to override precedence. +(6) Returns the result of (2-/expr/). +(7) Returns the result of min(/expr/, /expr/). +(8) Returns the result of max(/expr/, /expr/). + +An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 +respectively for calculations). A menu entry becomes visible when its +expression evaluates to 'm' or 'y'. + +There are two types of symbols: constant and non-constant symbols. +Non-constant symbols are the most common ones and are defined with the +'config' statement. Non-constant symbols consist entirely of alphanumeric +characters or underscores. +Constant symbols are only part of expressions. Constant symbols are +always surrounded by single or double quotes. Within the quote, any +other character is allowed and the quotes can be escaped using '\'. + +Menu structure +-------------- + +The position of a menu entry in the tree is determined in two ways. First +it can be specified explicitly:: + + menu "Network device support" + depends on NET + + config NETDEVICES + ... + + endmenu + +All entries within the "menu" ... "endmenu" block become a submenu of +"Network device support". All subentries inherit the dependencies from +the menu entry, e.g. this means the dependency "NET" is added to the +dependency list of the config option NETDEVICES. + +The other way to generate the menu structure is done by analyzing the +dependencies. If a menu entry somehow depends on the previous entry, it +can be made a submenu of it. First, the previous (parent) symbol must +be part of the dependency list and then one of these two conditions +must be true: + +- the child entry must become invisible, if the parent is set to 'n' +- the child entry must only be visible, if the parent is visible:: + + config MODULES + bool "Enable loadable module support" + + config MODVERSIONS + bool "Set version information on all module symbols" + depends on MODULES + + comment "module support disabled" + depends on !MODULES + +MODVERSIONS directly depends on MODULES, this means it's only visible if +MODULES is different from 'n'. The comment on the other hand is only +visible when MODULES is set to 'n'. + + +Kconfig syntax +-------------- + +The configuration file describes a series of menu entries, where every +line starts with a keyword (except help texts). The following keywords +end a menu entry: + +- config +- menuconfig +- choice/endchoice +- comment +- menu/endmenu +- if/endif +- source + +The first five also start the definition of a menu entry. + +config:: + "config" + + +This defines a config symbol and accepts any of above +attributes as options. + +menuconfig:: + "menuconfig" + + +This is similar to the simple config entry above, but it also gives a +hint to front ends, that all suboptions should be displayed as a +separate list of options. To make sure all the suboptions will really +show up under the menuconfig entry and not outside of it, every item +from the list must depend on the menuconfig symbol. +In practice, this is achieved by using one of the next two constructs:: + + (1): + menuconfig M + if M + config C1 + config C2 + endif + + (2): + menuconfig M + config C1 + depends on M + config C2 + depends on M + +In the following examples (3) and (4), C1 and C2 still have the M +dependency, but will not appear under menuconfig M anymore, because +of C0, which doesn't depend on M:: + + (3): + menuconfig M + config C0 + if M + config C1 + config C2 + endif + + (4): + menuconfig M + config C0 + config C1 + depends on M + config C2 + depends on M + +choices:: + + "choice" [symbol] + + + "endchoice" + +This defines a choice group and accepts any of the above attributes as +options. A choice can only be of type bool or tristate. If no type is +specified for a choice, its type will be determined by the type of +the first choice element in the group or remain unknown if none of the +choice elements have a type specified, as well. + +While a boolean choice only allows a single config entry to be +selected, a tristate choice also allows any number of config entries +to be set to 'm'. This can be used if multiple drivers for a single +hardware exists and only a single driver can be compiled/loaded into +the kernel, but all drivers can be compiled as modules. + +A choice accepts another option "optional", which allows to set the +choice to 'n' and no entry needs to be selected. +If no [symbol] is associated with a choice, then you can not have multiple +definitions of that choice. If a [symbol] is associated to the choice, +then you may define the same choice (i.e. with the same entries) in another +place. + +comment:: + + "comment" + + +This defines a comment which is displayed to the user during the +configuration process and is also echoed to the output files. The only +possible options are dependencies. + +menu:: + + "menu" + + + "endmenu" + +This defines a menu block, see "Menu structure" above for more +information. The only possible options are dependencies and "visible" +attributes. + +if:: + + "if" + + "endif" + +This defines an if block. The dependency expression is appended +to all enclosed menu entries. + +source:: + + "source" + +This reads the specified configuration file. This file is always parsed. + +mainmenu:: + + "mainmenu" + +This sets the config program's title bar if the config program chooses +to use it. It should be placed at the top of the configuration, before any +other statement. + +'#' Kconfig source file comment: + +An unquoted '#' character anywhere in a source file line indicates +the beginning of a source file comment. The remainder of that line +is a comment. + + +Kconfig hints +------------- +This is a collection of Kconfig tips, most of which aren't obvious at +first glance and most of which have become idioms in several Kconfig +files. + +Adding common features and make the usage configurable +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +It is a common idiom to implement a feature/functionality that are +relevant for some architectures but not all. +The recommended way to do so is to use a config variable named HAVE_* +that is defined in a common Kconfig file and selected by the relevant +architectures. +An example is the generic IOMAP functionality. + +We would in lib/Kconfig see:: + + # Generic IOMAP is used to ... + config HAVE_GENERIC_IOMAP + + config GENERIC_IOMAP + depends on HAVE_GENERIC_IOMAP && FOO + +And in lib/Makefile we would see:: + + obj-$(CONFIG_GENERIC_IOMAP) += iomap.o + +For each architecture using the generic IOMAP functionality we would see:: + + config X86 + select ... + select HAVE_GENERIC_IOMAP + select ... + +Note: we use the existing config option and avoid creating a new +config variable to select HAVE_GENERIC_IOMAP. + +Note: the use of the internal config variable HAVE_GENERIC_IOMAP, it is +introduced to overcome the limitation of select which will force a +config option to 'y' no matter the dependencies. +The dependencies are moved to the symbol GENERIC_IOMAP and we avoid the +situation where select forces a symbol equals to 'y'. + +Adding features that need compiler support +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +There are several features that need compiler support. The recommended way +to describe the dependency on the compiler feature is to use "depends on" +followed by a test macro:: + + config STACKPROTECTOR + bool "Stack Protector buffer overflow detection" + depends on $(cc-option,-fstack-protector) + ... + +If you need to expose a compiler capability to makefiles and/or C source files, +`CC_HAS_` is the recommended prefix for the config option:: + + config CC_HAS_STACKPROTECTOR_NONE + def_bool $(cc-option,-fno-stack-protector) + +Build as module only +~~~~~~~~~~~~~~~~~~~~ +To restrict a component build to module-only, qualify its config symbol +with "depends on m". E.g.:: + + config FOO + depends on BAR && m + +limits FOO to module (=m) or disabled (=n). + +Kconfig recursive dependency limitations +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If you've hit the Kconfig error: "recursive dependency detected" you've run +into a recursive dependency issue with Kconfig, a recursive dependency can be +summarized as a circular dependency. The kconfig tools need to ensure that +Kconfig files comply with specified configuration requirements. In order to do +that kconfig must determine the values that are possible for all Kconfig +symbols, this is currently not possible if there is a circular relation +between two or more Kconfig symbols. For more details refer to the "Simple +Kconfig recursive issue" subsection below. Kconfig does not do recursive +dependency resolution; this has a few implications for Kconfig file writers. +We'll first explain why this issues exists and then provide an example +technical limitation which this brings upon Kconfig developers.

These dependencies are used -to determine the visibility of an entry. Any child entry is only -visible if its parent entry is also visible. - -Menu entries ------------- - -Most entries define a config option; all other entries help to organize -them. A single configuration option is defined like this: - -config MODVERSIONS - bool "Set version information on all module symbols" - depends on MODULES - help - Usually, modules have to be recompiled whenever you switch to a new - kernel. ... - -Every line starts with a key word and can be followed by multiple -arguments. "config" starts a new config entry. The following lines -define attributes for this config option. Attributes can be the type of -the config option, input prompt, dependencies, help text and default -values. A config option can be defined multiple times with the same -name, but every definition can have only a single input prompt and the -type must not conflict. - -Menu attributes ---------------- - -A menu entry can have a number of attributes. Not all of them are -applicable everywhere (see syntax). - -- type definition: "bool"/"tristate"/"string"/"hex"/"int" - Every config option must have a type. There are only two basic types: - tristate and string; the other types are based on these two. The type - definition optionally accepts an input prompt, so these two examples - are equivalent: - - bool "Networking support" - and - bool - prompt "Networking support" - -- input prompt: "prompt" ["if" ] - Every menu entry can have at most one prompt, which is used to display - to the user. Optionally dependencies only for this prompt can be added - with "if". - -- default value: "default" ["if" ] - A config option can have any number of default values. If multiple - default values are visible, only the first defined one is active. - Default values are not limited to the menu entry where they are - defined. This means the default can be defined somewhere else or be - overridden by an earlier definition. - The default value is only assigned to the config symbol if no other - value was set by the user (via the input prompt above). If an input - prompt is visible the default value is presented to the user and can - be overridden by him. - Optionally, dependencies only for this default value can be added with - "if". - - The default value deliberately defaults to 'n' in order to avoid bloating the - build. With few exceptions, new config options should not change this. The - intent is for "make oldconfig" to add as little as possible to the config from - release to release. - - Note: - Things that merit "default y/m" include: - - a) A new Kconfig option for something that used to always be built - should be "default y". - - b) A new gatekeeping Kconfig option that hides/shows other Kconfig - options (but does not generate any code of its own), should be - "default y" so people will see those other options. - - c) Sub-driver behavior or similar options for a driver that is - "default n". This allows you to provide sane defaults. - - d) Hardware or infrastructure that everybody expects, such as CONFIG_NET - or CONFIG_BLOCK. These are rare exceptions. - -- type definition + default value: - "def_bool"/"def_tristate" ["if" ] - This is a shorthand notation for a type definition plus a value. - Optionally dependencies for this default value can be added with "if". - -- dependencies: "depends on" - This defines a dependency for this menu entry. If multiple - dependencies are defined, they are connected with '&&'. Dependencies - are applied to all other options within this menu entry (which also - accept an "if" expression), so these two examples are equivalent: - - bool "foo" if BAR - default y if BAR - and - depends on BAR - bool "foo" - default y - -- reverse dependencies: "select" ["if" ] - While normal dependencies reduce the upper limit of a symbol (see - below), reverse dependencies can be used to force a lower limit of - another symbol. The value of the current menu symbol is used as the - minimal value can be set to. If is selected multiple - times, the limit is set to the largest selection. - Reverse dependencies can only be used with boolean or tristate - symbols. - Note: - select should be used with care. select will force - a symbol to a value without visiting the dependencies. - By abusing select you are able to select a symbol FOO even - if FOO depends on BAR that is not set. - In general use select only for non-visible symbols - (no prompts anywhere) and for symbols with no dependencies. - That will limit the usefulness but on the other hand avoid - the illegal configurations all over. - -- weak reverse dependencies: "imply" ["if" ] - This is similar to "select" as it enforces a lower limit on another - symbol except that the "implied" symbol's value may still be set to n - from a direct dependency or with a visible prompt. - - Given the following example: - - config FOO - tristate - imply BAZ - - config BAZ - tristate - depends on BAR - - The following values are possible: - - FOO BAR BAZ's default choice for BAZ - --- --- ------------- -------------- - n y n N/m/y - m y m M/y/n - y y y Y/n - y n * N - - This is useful e.g. with multiple drivers that want to indicate their - ability to hook into a secondary subsystem while allowing the user to - configure that subsystem out without also having to unset these drivers. - -- limiting menu display: "visible if" - This attribute is only applicable to menu blocks, if the condition is - false, the menu block is not displayed to the user (the symbols - contained there can still be selected by other symbols, though). It is - similar to a conditional "prompt" attribute for individual menu - entries. Default value of "visible" is true. - -- numerical ranges: "range" ["if" ] - This allows to limit the range of possible input values for int - and hex symbols. The user can only input a value which is larger than - or equal to the first symbol and smaller than or equal to the second - symbol. - -- help text: "help" or "---help---" - This defines a help text. The end of the help text is determined by - the indentation level, this means it ends at the first line which has - a smaller indentation than the first line of the help text. - "---help---" and "help" do not differ in behaviour, "---help---" is - used to help visually separate configuration logic from help within - the file as an aid to developers. - -- misc options: "option" [=] - Various less common options can be defined via this option syntax, - which can modify the behaviour of the menu entry and its config - symbol. These options are currently possible: - - - "defconfig_list" - This declares a list of default entries which can be used when - looking for the default configuration (which is used when the main - .config doesn't exists yet.) - - - "modules" - This declares the symbol to be used as the MODULES symbol, which - enables the third modular state for all config symbols. - At most one symbol may have the "modules" option set. - - - "allnoconfig_y" - This declares the symbol as one that should have the value y when - using "allnoconfig". Used for symbols that hide other symbols. - -Menu dependencies ------------------ - -Dependencies define the visibility of a menu entry and can also reduce -the input range of tristate symbols. The tristate logic used in the -expressions uses one more state than normal boolean logic to express the -module state. Dependency expressions have the following syntax: - - ::= (1) - '=' (2) - '!=' (3) - '<' (4) - '>' (4) - '<=' (4) - '>=' (4) - '(' ')' (5) - '!' (6) - '&&' (7) - '||' (8) - -Expressions are listed in decreasing order of precedence. - -(1) Convert the symbol into an expression. Boolean and tristate symbols - are simply converted into the respective expression values. All - other symbol types result in 'n'. -(2) If the values of both symbols are equal, it returns 'y', - otherwise 'n'. -(3) If the values of both symbols are equal, it returns 'n', - otherwise 'y'. -(4) If value of is respectively lower, greater, lower-or-equal, - or greater-or-equal than value of , it returns 'y', - otherwise 'n'. -(5) Returns the value of the expression. Used to override precedence. -(6) Returns the result of (2-/expr/). -(7) Returns the result of min(/expr/, /expr/). -(8) Returns the result of max(/expr/, /expr/). - -An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 -respectively for calculations). A menu entry becomes visible when its -expression evaluates to 'm' or 'y'. - -There are two types of symbols: constant and non-constant symbols. -Non-constant symbols are the most common ones and are defined with the -'config' statement. Non-constant symbols consist entirely of alphanumeric -characters or underscores. -Constant symbols are only part of expressions. Constant symbols are -always surrounded by single or double quotes. Within the quote, any -other character is allowed and the quotes can be escaped using '\'. - -Menu structure --------------- - -The position of a menu entry in the tree is determined in two ways. First -it can be specified explicitly: - -menu "Network device support" - depends on NET - -config NETDEVICES - ... - -endmenu - -All entries within the "menu" ... "endmenu" block become a submenu of -"Network device support". All subentries inherit the dependencies from -the menu entry, e.g. this means the dependency "NET" is added to the -dependency list of the config option NETDEVICES. - -The other way to generate the menu structure is done by analyzing the -dependencies. If a menu entry somehow depends on the previous entry, it -can be made a submenu of it. First, the previous (parent) symbol must -be part of the dependency list and then one of these two conditions -must be true: -- the child entry must become invisible, if the parent is set to 'n' -- the child entry must only be visible, if the parent is visible - -config MODULES - bool "Enable loadable module support" - -config MODVERSIONS - bool "Set version information on all module symbols" - depends on MODULES - -comment "module support disabled" - depends on !MODULES - -MODVERSIONS directly depends on MODULES, this means it's only visible if -MODULES is different from 'n'. The comment on the other hand is only -visible when MODULES is set to 'n'. - - -Kconfig syntax --------------- - -The configuration file describes a series of menu entries, where every -line starts with a keyword (except help texts). The following keywords -end a menu entry: -- config -- menuconfig -- choice/endchoice -- comment -- menu/endmenu -- if/endif -- source -The first five also start the definition of a menu entry. - -config: - - "config" - - -This defines a config symbol and accepts any of above -attributes as options. - -menuconfig: - "menuconfig" - - -This is similar to the simple config entry above, but it also gives a -hint to front ends, that all suboptions should be displayed as a -separate list of options. To make sure all the suboptions will really -show up under the menuconfig entry and not outside of it, every item -from the list must depend on the menuconfig symbol. -In practice, this is achieved by using one of the next two constructs: - -(1): -menuconfig M -if M - config C1 - config C2 -endif - -(2): -menuconfig M -config C1 - depends on M -config C2 - depends on M - -In the following examples (3) and (4), C1 and C2 still have the M -dependency, but will not appear under menuconfig M anymore, because -of C0, which doesn't depend on M: - -(3): -menuconfig M - config C0 -if M - config C1 - config C2 -endif - -(4): -menuconfig M -config C0 -config C1 - depends on M -config C2 - depends on M - -choices: - - "choice" [symbol] - - - "endchoice" - -This defines a choice group and accepts any of the above attributes as -options. A choice can only be of type bool or tristate. If no type is -specified for a choice, its type will be determined by the type of -the first choice element in the group or remain unknown if none of the -choice elements have a type specified, as well. - -While a boolean choice only allows a single config entry to be -selected, a tristate choice also allows any number of config entries -to be set to 'm'. This can be used if multiple drivers for a single -hardware exists and only a single driver can be compiled/loaded into -the kernel, but all drivers can be compiled as modules. - -A choice accepts another option "optional", which allows to set the -choice to 'n' and no entry needs to be selected. -If no [symbol] is associated with a choice, then you can not have multiple -definitions of that choice. If a [symbol] is associated to the choice, -then you may define the same choice (i.e. with the same entries) in another -place. - -comment: - - "comment" - - -This defines a comment which is displayed to the user during the -configuration process and is also echoed to the output files. The only -possible options are dependencies. - -menu: - - "menu" - - - "endmenu" - -This defines a menu block, see "Menu structure" above for more -information. The only possible options are dependencies and "visible" -attributes. - -if: - - "if" - - "endif" - -This defines an if block. The dependency expression is appended -to all enclosed menu entries. - -source: - - "source" - -This reads the specified configuration file. This file is always parsed. - -mainmenu: - - "mainmenu" - -This sets the config program's title bar if the config program chooses -to use it. It should be placed at the top of the configuration, before any -other statement. - -'#' Kconfig source file comment: - -An unquoted '#' character anywhere in a source file line indicates -the beginning of a source file comment. The remainder of that line -is a comment. - - -Kconfig hints -------------- -This is a collection of Kconfig tips, most of which aren't obvious at -first glance and most of which have become idioms in several Kconfig -files. - -Adding common features and make the usage configurable -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -It is a common idiom to implement a feature/functionality that are -relevant for some architectures but not all. -The recommended way to do so is to use a config variable named HAVE_* -that is defined in a common Kconfig file and selected by the relevant -architectures. -An example is the generic IOMAP functionality. - -We would in lib/Kconfig see: - -# Generic IOMAP is used to ... -config HAVE_GENERIC_IOMAP - -config GENERIC_IOMAP - depends on HAVE_GENERIC_IOMAP && FOO - -And in lib/Makefile we would see: -obj-$(CONFIG_GENERIC_IOMAP) += iomap.o - -For each architecture using the generic IOMAP functionality we would see: - -config X86 - select ... - select HAVE_GENERIC_IOMAP - select ... - -Note: we use the existing config option and avoid creating a new -config variable to select HAVE_GENERIC_IOMAP. - -Note: the use of the internal config variable HAVE_GENERIC_IOMAP, it is -introduced to overcome the limitation of select which will force a -config option to 'y' no matter the dependencies. -The dependencies are moved to the symbol GENERIC_IOMAP and we avoid the -situation where select forces a symbol equals to 'y'. - -Adding features that need compiler support -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -There are several features that need compiler support. The recommended way -to describe the dependency on the compiler feature is to use "depends on" -followed by a test macro. - -config STACKPROTECTOR - bool "Stack Protector buffer overflow detection" - depends on $(cc-option,-fstack-protector) - ... - -If you need to expose a compiler capability to makefiles and/or C source files, -CC_HAS_ is the recommended prefix for the config option. - -config CC_HAS_STACKPROTECTOR_NONE - def_bool $(cc-option,-fno-stack-protector) - -Build as module only -~~~~~~~~~~~~~~~~~~~~ -To restrict a component build to module-only, qualify its config symbol -with "depends on m". E.g.: - -config FOO - depends on BAR && m - -limits FOO to module (=m) or disabled (=n). - -Kconfig recursive dependency limitations -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -If you've hit the Kconfig error: "recursive dependency detected" you've run -into a recursive dependency issue with Kconfig, a recursive dependency can be -summarized as a circular dependency. The kconfig tools need to ensure that -Kconfig files comply with specified configuration requirements. In order to do -that kconfig must determine the values that are possible for all Kconfig -symbols, this is currently not possible if there is a circular relation -between two or more Kconfig symbols. For more details refer to the "Simple -Kconfig recursive issue" subsection below.

The top Makefile textually includes an arch Makefile +with the name arch/$(ARCH)/Makefile. The arch Makefile supplies +architecture-specific information to the top Makefile. + +Each subdirectory has a kbuild Makefile which carries out the commands +passed down from above. The kbuild Makefile uses information from the +.config file to construct various file lists used by kbuild to build +any built-in or modular targets. + +scripts/Makefile.* contains all the definitions/rules etc. that +are used to build the kernel based on the kbuild makefiles. + + +2 Who does what +=============== + +People have four different relationships with the kernel Makefiles. + +*Users* are people who build kernels. These people type commands such as +"make menuconfig" or "make". They usually do not read or edit +any kernel Makefiles (or any other source files). + +*Normal developers* are people who work on features such as device +drivers, file systems, and network protocols. These people need to +maintain the kbuild Makefiles for the subsystem they are +working on. In order to do this effectively, they need some overall +knowledge about the kernel Makefiles, plus detailed knowledge about the +public interface for kbuild. + +*Arch developers* are people who work on an entire architecture, such +as sparc or ia64. Arch developers need to know about the arch Makefile +as well as kbuild Makefiles. + +*Kbuild developers* are people who work on the kernel build system itself. +These people need to know about all aspects of the kernel Makefiles. + +This document is aimed towards normal developers and arch developers. + + +3 The kbuild files +================== + +Most Makefiles within the kernel are kbuild Makefiles that use the +kbuild infrastructure. This chapter introduces the syntax used in the +kbuild makefiles. +The preferred name for the kbuild files are 'Makefile' but 'Kbuild' can +be used and if both a 'Makefile' and a 'Kbuild' file exists, then the 'Kbuild' +file will be used. + +Section 3.1 "Goal definitions" is a quick intro, further chapters provide +more details, with real examples. + +3.1 Goal definitions +-------------------- + + Goal definitions are the main part (heart) of the kbuild Makefile. + These lines define the files to be built, any special compilation + options, and any subdirectories to be entered recursively. + + The most simple kbuild makefile contains one line: + + Example:: + + obj-y += foo.o + + This tells kbuild that there is one object in that directory, named + foo.o. foo.o will be built from foo.c or foo.S. + + If foo.o shall be built as a module, the variable obj-m is used. + Therefore the following pattern is often used: + + Example:: + + obj-$(CONFIG_FOO) += foo.o + + $(CONFIG_FOO) evaluates to either y (for built-in) or m (for module). + If CONFIG_FOO is neither y nor m, then the file will not be compiled + nor linked. + +3.2 Built-in object goals - obj-y +--------------------------------- + + The kbuild Makefile specifies object files for vmlinux + in the $(obj-y) lists. These lists depend on the kernel + configuration. + + Kbuild compiles all the $(obj-y) files. It then calls + "$(AR) rcSTP" to merge these files into one built-in.a file. + This is a thin archive without a symbol table. It will be later + linked into vmlinux by scripts/link-vmlinux.sh + + The order of files in $(obj-y) is significant. Duplicates in + the lists are allowed: the first instance will be linked into + built-in.a and succeeding instances will be ignored. + + Link order is significant, because certain functions + (module_init() / __initcall) will be called during boot in the + order they appear. So keep in mind that changing the link + order may e.g. change the order in which your SCSI + controllers are detected, and thus your disks are renumbered. + + Example:: + + #drivers/isdn/i4l/Makefile + # Makefile for the kernel ISDN subsystem and device drivers. + # Each configuration option enables a list of files. + obj-$(CONFIG_ISDN_I4L) += isdn.o + obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o + +3.3 Loadable module goals - obj-m +--------------------------------- + + $(obj-m) specifies object files which are built as loadable + kernel modules. + + A module may be built from one source file or several source + files. In the case of one source file, the kbuild makefile + simply adds the file to $(obj-m). + + Example:: + + #drivers/isdn/i4l/Makefile + obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o + + Note: In this example $(CONFIG_ISDN_PPP_BSDCOMP) evaluates to 'm' + + If a kernel module is built from several source files, you specify + that you want to build a module in the same way as above; however, + kbuild needs to know which object files you want to build your + module from, so you have to tell it by setting a $(-y) + variable. + + Example:: + + #drivers/isdn/i4l/Makefile + obj-$(CONFIG_ISDN_I4L) += isdn.o + isdn-y := isdn_net_lib.o isdn_v110.o isdn_common.o + + In this example, the module name will be isdn.o. Kbuild will + compile the objects listed in $(isdn-y) and then run + "$(LD) -r" on the list of these files to generate isdn.o. + + Due to kbuild recognizing $(-y) for composite objects, + you can use the value of a `CONFIG_` symbol to optionally include an + object file as part of a composite object. + + Example:: + + #fs/ext2/Makefile + obj-$(CONFIG_EXT2_FS) += ext2.o + ext2-y := balloc.o dir.o file.o ialloc.o inode.o ioctl.o \ + namei.o super.o symlink.o + ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o xattr_user.o \ + xattr_trusted.o + + In this example, xattr.o, xattr_user.o and xattr_trusted.o are only + part of the composite object ext2.o if $(CONFIG_EXT2_FS_XATTR) + evaluates to 'y'. + + Note: Of course, when you are building objects into the kernel, + the syntax above will also work. So, if you have CONFIG_EXT2_FS=y, + kbuild will build an ext2.o file for you out of the individual + parts and then link this into built-in.a, as you would expect. + +3.4 Objects which export symbols +-------------------------------- + + No special notation is required in the makefiles for + modules exporting symbols. + +3.5 Library file goals - lib-y +------------------------------ + + Objects listed with obj-* are used for modules, or + combined in a built-in.a for that specific directory. + There is also the possibility to list objects that will + be included in a library, lib.a. + All objects listed with lib-y are combined in a single + library for that directory. + Objects that are listed in obj-y and additionally listed in + lib-y will not be included in the library, since they will + be accessible anyway. + For consistency, objects listed in lib-m will be included in lib.a. + + Note that the same kbuild makefile may list files to be built-in + and to be part of a library. Therefore the same directory + may contain both a built-in.a and a lib.a file. + + Example:: + + #arch/x86/lib/Makefile + lib-y := delay.o + + This will create a library lib.a based on delay.o. For kbuild to + actually recognize that there is a lib.a being built, the directory + shall be listed in libs-y. + + See also "6.4 List directories to visit when descending". + + Use of lib-y is normally restricted to `lib/` and `arch/*/lib`. + +3.6 Descending down in directories +---------------------------------- + + A Makefile is only responsible for building objects in its own + directory. Files in subdirectories should be taken care of by + Makefiles in these subdirs. The build system will automatically + invoke make recursively in subdirectories, provided you let it know of + them. + + To do so, obj-y and obj-m are used. + ext2 lives in a separate directory, and the Makefile present in fs/ + tells kbuild to descend down using the following assignment. + + Example:: + + #fs/Makefile + obj-$(CONFIG_EXT2_FS) += ext2/ + + If CONFIG_EXT2_FS is set to either 'y' (built-in) or 'm' (modular) + the corresponding obj- variable will be set, and kbuild will descend + down in the ext2 directory. + Kbuild only uses this information to decide that it needs to visit + the directory, it is the Makefile in the subdirectory that + specifies what is modular and what is built-in. + + It is good practice to use a `CONFIG_` variable when assigning directory + names. This allows kbuild to totally skip the directory if the + corresponding `CONFIG_` option is neither 'y' nor 'm'. + +3.7 Compilation flags +--------------------- + + ccflags-y, asflags-y and ldflags-y + These three flags apply only to the kbuild makefile in which they + are assigned. They are used for all the normal cc, as and ld + invocations happening during a recursive build. + Note: Flags with the same behaviour were previously named: + EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS. + They are still supported but their usage is deprecated. + + ccflags-y specifies options for compiling with $(CC). + + Example:: + + # drivers/acpi/acpica/Makefile + ccflags-y := -Os -D_LINUX -DBUILDING_ACPICA + ccflags-$(CONFIG_ACPI_DEBUG) += -DACPI_DEBUG_OUTPUT + + This variable is necessary because the top Makefile owns the + variable $(KBUILD_CFLAGS) and uses it for compilation flags for the + entire tree. + + asflags-y specifies options for assembling with $(AS). + + Example:: + + #arch/sparc/kernel/Makefile + asflags-y := -ansi + + ldflags-y specifies options for linking with $(LD). + + Example:: + + #arch/cris/boot/compressed/Makefile + ldflags-y += -T $(srctree)/$(src)/decompress_$(arch-y).lds + + subdir-ccflags-y, subdir-asflags-y + The two flags listed above are similar to ccflags-y and asflags-y. + The difference is that the subdir- variants have effect for the kbuild + file where they are present and all subdirectories. + Options specified using subdir-* are added to the commandline before + the options specified using the non-subdir variants. + + Example:: + + subdir-ccflags-y := -Werror + + CFLAGS_$@, AFLAGS_$@ + CFLAGS_$@ and AFLAGS_$@ only apply to commands in current + kbuild makefile. + + $(CFLAGS_$@) specifies per-file options for $(CC). The $@ + part has a literal value which specifies the file that it is for. + + Example:: + + # drivers/scsi/Makefile + CFLAGS_aha152x.o = -DAHA152X_STAT -DAUTOCONF + CFLAGS_gdth.o = # -DDEBUG_GDTH=2 -D__SERIAL__ -D__COM2__ \ + -DGDTH_STATISTICS + + These two lines specify compilation flags for aha152x.o and gdth.o. + + $(AFLAGS_$@) is a similar feature for source files in assembly + languages. + + Example:: + + # arch/arm/kernel/Makefile + AFLAGS_head.o := -DTEXT_OFFSET=$(TEXT_OFFSET) + AFLAGS_crunch-bits.o := -Wa,-mcpu=ep9312 + AFLAGS_iwmmxt.o := -Wa,-mcpu=iwmmxt + + +3.9 Dependency tracking +----------------------- + + Kbuild tracks dependencies on the following: + 1) All prerequisite files (both `*.c` and `*.h`) + 2) `CONFIG_` options used in all prerequisite files + 3) Command-line used to compile target + + Thus, if you change an option to $(CC) all affected files will + be re-compiled. + +3.10 Special Rules +------------------ + + Special rules are used when the kbuild infrastructure does + not provide the required support. A typical example is + header files generated during the build process. + Another example are the architecture-specific Makefiles which + need special rules to prepare boot images etc. + + Special rules are written as normal Make rules. + Kbuild is not executing in the directory where the Makefile is + located, so all special rules shall provide a relative + path to prerequisite files and target files. + + Two variables are used when defining special rules: + + $(src) + $(src) is a relative path which points to the directory + where the Makefile is located. Always use $(src) when + referring to files located in the src tree. + + $(obj) + $(obj) is a relative path which points to the directory + where the target is saved. Always use $(obj) when + referring to generated files. + + Example:: + + #drivers/scsi/Makefile + $(obj)/53c8xx_d.h: $(src)/53c7,8xx.scr $(src)/script_asm.pl + $(CPP) -DCHIP=810 - < $< | ... $(src)/script_asm.pl + + This is a special rule, following the normal syntax + required by make. + + The target file depends on two prerequisite files. References + to the target file are prefixed with $(obj), references + to prerequisites are referenced with $(src) (because they are not + generated files). + + $(kecho) + echoing information to user in a rule is often a good practice + but when execution "make -s" one does not expect to see any output + except for warnings/errors. + To support this kbuild defines $(kecho) which will echo out the + text following $(kecho) to stdout except if "make -s" is used. + + Example:: + + #arch/blackfin/boot/Makefile + $(obj)/vmImage: $(obj)/vmlinux.gz + $(call if_changed,uimage) + @$(kecho) 'Kernel: $@ is ready' + + +3.11 $(CC) support functions +---------------------------- + + The kernel may be built with several different versions of + $(CC), each supporting a unique set of features and options. + kbuild provides basic support to check for valid options for $(CC). + $(CC) is usually the gcc compiler, but other alternatives are + available. + + as-option + as-option is used to check if $(CC) -- when used to compile + assembler (`*.S`) files -- supports the given option. An optional + second option may be specified if the first option is not supported. + + Example:: + + #arch/sh/Makefile + cflags-y += $(call as-option,-Wa$(comma)-isa=$(isa-y),) + + In the above example, cflags-y will be assigned the option + -Wa$(comma)-isa=$(isa-y) if it is supported by $(CC). + The second argument is optional, and if supplied will be used + if first argument is not supported. + + cc-ldoption + cc-ldoption is used to check if $(CC) when used to link object files + supports the given option. An optional second option may be + specified if first option are not supported. + + Example:: + + #arch/x86/kernel/Makefile + vsyscall-flags += $(call cc-ldoption, -Wl$(comma)--hash-style=sysv) + + In the above example, vsyscall-flags will be assigned the option + -Wl$(comma)--hash-style=sysv if it is supported by $(CC). + The second argument is optional, and if supplied will be used + if first argument is not supported. + + as-instr + as-instr checks if the assembler reports a specific instruction + and then outputs either option1 or option2 + C escapes are supported in the test instruction + Note: as-instr-option uses KBUILD_AFLAGS for $(AS) options + + cc-option + cc-option is used to check if $(CC) supports a given option, and if + not supported to use an optional second option. + + Example:: + + #arch/x86/Makefile + cflags-y += $(call cc-option,-march=pentium-mmx,-march=i586) + + In the above example, cflags-y will be assigned the option + -march=pentium-mmx if supported by $(CC), otherwise -march=i586. + The second argument to cc-option is optional, and if omitted, + cflags-y will be assigned no value if first option is not supported. + Note: cc-option uses KBUILD_CFLAGS for $(CC) options + + cc-option-yn + cc-option-yn is used to check if gcc supports a given option + and return 'y' if supported, otherwise 'n'. + + Example:: + + #arch/ppc/Makefile + biarch := $(call cc-option-yn, -m32) + aflags-$(biarch) += -a32 + cflags-$(biarch) += -m32 + + In the above example, $(biarch) is set to y if $(CC) supports the -m32 + option. When $(biarch) equals 'y', the expanded variables $(aflags-y) + and $(cflags-y) will be assigned the values -a32 and -m32, + respectively. + Note: cc-option-yn uses KBUILD_CFLAGS for $(CC) options + + cc-disable-warning + cc-disable-warning checks if gcc supports a given warning and returns + the commandline switch to disable it. This special function is needed, + because gcc 4.4 and later accept any unknown -Wno-* option and only + warn about it if there is another warning in the source file. + + Example:: + + KBUILD_CFLAGS += $(call cc-disable-warning, unused-but-set-variable) + + In the above example, -Wno-unused-but-set-variable will be added to + KBUILD_CFLAGS only if gcc really accepts it. + + cc-ifversion + cc-ifversion tests the version of $(CC) and equals the fourth parameter + if version expression is true, or the fifth (if given) if the version + expression is false. + + Example:: + + #fs/reiserfs/Makefile + ccflags-y := $(call cc-ifversion, -lt, 0402, -O1) + + In this example, ccflags-y will be assigned the value -O1 if the + $(CC) version is less than 4.2. + cc-ifversion takes all the shell operators: + -eq, -ne, -lt, -le, -gt, and -ge + The third parameter may be a text as in this example, but it may also + be an expanded variable or a macro. + + cc-cross-prefix + cc-cross-prefix is used to check if there exists a $(CC) in path with + one of the listed prefixes. The first prefix where there exist a + prefix$(CC) in the PATH is returned - and if no prefix$(CC) is found + then nothing is returned. + Additional prefixes are separated by a single space in the + call of cc-cross-prefix. + This functionality is useful for architecture Makefiles that try + to set CROSS_COMPILE to well-known values but may have several + values to select between. + It is recommended only to try to set CROSS_COMPILE if it is a cross + build (host arch is different from target arch). And if CROSS_COMPILE + is already set then leave it with the old value. + + Example:: + + #arch/m68k/Makefile + ifneq ($(SUBARCH),$(ARCH)) + ifeq ($(CROSS_COMPILE),) + CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu-) + endif + endif + +3.12 $(LD) support functions +---------------------------- + + ld-option + ld-option is used to check if $(LD) supports the supplied option. + ld-option takes two options as arguments. + The second argument is an optional option that can be used if the + first option is not supported by $(LD). + + Example:: + + #Makefile + LDFLAGS_vmlinux += $(call ld-option, -X) + + +4 Host Program support +====================== + +Kbuild supports building executables on the host for use during the +compilation stage. +Two steps are required in order to use a host executable. + +The first step is to tell kbuild that a host program exists. This is +done utilising the variable hostprogs-y. + +The second step is to add an explicit dependency to the executable. +This can be done in two ways. Either add the dependency in a rule, +or utilise the variable $(always). +Both possibilities are described in the following. + +4.1 Simple Host Program +----------------------- + + In some cases there is a need to compile and run a program on the + computer where the build is running. + The following line tells kbuild that the program bin2hex shall be + built on the build host. + + Example:: + + hostprogs-y := bin2hex + + Kbuild assumes in the above example that bin2hex is made from a single + c-source file named bin2hex.c located in the same directory as + the Makefile. + +4.2 Composite Host Programs +--------------------------- + + Host programs can be made up based on composite objects. + The syntax used to define composite objects for host programs is + similar to the syntax used for kernel objects. + $(-objs) lists all objects used to link the final + executable. + + Example:: + + #scripts/lxdialog/Makefile + hostprogs-y := lxdialog + lxdialog-objs := checklist.o lxdialog.o + + Objects with extension .o are compiled from the corresponding .c + files. In the above example, checklist.c is compiled to checklist.o + and lxdialog.c is compiled to lxdialog.o. + + Finally, the two .o files are linked to the executable, lxdialog. + Note: The syntax -y is not permitted for host-programs. + +4.3 Using C++ for host programs +------------------------------- + + kbuild offers support for host programs written in C++. This was + introduced solely to support kconfig, and is not recommended + for general use. + + Example:: + + #scripts/kconfig/Makefile + hostprogs-y := qconf + qconf-cxxobjs := qconf.o + + In the example above the executable is composed of the C++ file + qconf.cc - identified by $(qconf-cxxobjs). + + If qconf is composed of a mixture of .c and .cc files, then an + additional line can be used to identify this. + + Example:: + + #scripts/kconfig/Makefile + hostprogs-y := qconf + qconf-cxxobjs := qconf.o + qconf-objs := check.o + +4.4 Controlling compiler options for host programs +-------------------------------------------------- + + When compiling host programs, it is possible to set specific flags. + The programs will always be compiled utilising $(HOSTCC) passed + the options specified in $(KBUILD_HOSTCFLAGS). + To set flags that will take effect for all host programs created + in that Makefile, use the variable HOST_EXTRACFLAGS. + + Example:: + + #scripts/lxdialog/Makefile + HOST_EXTRACFLAGS += -I/usr/include/ncurses + + To set specific flags for a single file the following construction + is used: + + Example:: + + #arch/ppc64/boot/Makefile + HOSTCFLAGS_piggyback.o := -DKERNELBASE=$(KERNELBASE) + + It is also possible to specify additional options to the linker. + + Example:: + + #scripts/kconfig/Makefile + HOSTLDLIBS_qconf := -L$(QTDIR)/lib + + When linking qconf, it will be passed the extra option + "-L$(QTDIR)/lib". + +4.5 When host programs are actually built +----------------------------------------- + + Kbuild will only build host-programs when they are referenced + as a prerequisite. + This is possible in two ways: + + (1) List the prerequisite explicitly in a special rule. + + Example:: + + #drivers/pci/Makefile + hostprogs-y := gen-devlist + $(obj)/devlist.h: $(src)/pci.ids $(obj)/gen-devlist + ( cd $(obj); ./gen-devlist ) < $< + + The target $(obj)/devlist.h will not be built before + $(obj)/gen-devlist is updated. Note that references to + the host programs in special rules must be prefixed with $(obj). + + (2) Use $(always) + + When there is no suitable special rule, and the host program + shall be built when a makefile is entered, the $(always) + variable shall be used. + + Example:: + + #scripts/lxdialog/Makefile + hostprogs-y := lxdialog + always := $(hostprogs-y) + + This will tell kbuild to build lxdialog even if not referenced in + any rule. + +4.6 Using hostprogs-$(CONFIG_FOO) +--------------------------------- + + A typical pattern in a Kbuild file looks like this: + + Example:: + + #scripts/Makefile + hostprogs-$(CONFIG_KALLSYMS) += kallsyms + + Kbuild knows about both 'y' for built-in and 'm' for module. + So if a config symbol evaluates to 'm', kbuild will still build + the binary. In other words, Kbuild handles hostprogs-m exactly + like hostprogs-y. But only hostprogs-y is recommended to be used + when no CONFIG symbols are involved. + +5 Kbuild clean infrastructure +============================= + +"make clean" deletes most generated files in the obj tree where the kernel +is compiled. This includes generated files such as host programs. +Kbuild knows targets listed in $(hostprogs-y), $(hostprogs-m), $(always), +$(extra-y) and $(targets). They are all deleted during "make clean". +Files matching the patterns "*.[oas]", "*.ko", plus some additional files +generated by kbuild are deleted all over the kernel src tree when +"make clean" is executed. + +Additional files can be specified in kbuild makefiles by use of $(clean-files). + + Example:: + + #lib/Makefile + clean-files := crc32table.h + +When executing "make clean", the file "crc32table.h" will be deleted. +Kbuild will assume files to be in the same relative directory as the +Makefile, except if prefixed with $(objtree). + +To delete a directory hierarchy use: + + Example:: + + #scripts/package/Makefile + clean-dirs := $(objtree)/debian/ + +This will delete the directory debian in the toplevel directory, including all +subdirectories. + +To exclude certain files from make clean, use the $(no-clean-files) variable. +This is only a special case used in the top level Kbuild file: + + Example:: + + #Kbuild + no-clean-files := $(bounds-file) $(offsets-file) + +Usually kbuild descends down in subdirectories due to "obj-* := dir/", +but in the architecture makefiles where the kbuild infrastructure +is not sufficient this sometimes needs to be explicit. + + Example:: + + #arch/x86/boot/Makefile + subdir- := compressed/ + +The above assignment instructs kbuild to descend down in the +directory compressed/ when "make clean" is executed. + +To support the clean infrastructure in the Makefiles that build the +final bootimage there is an optional target named archclean: + + Example:: + + #arch/x86/Makefile + archclean: + $(Q)$(MAKE) $(clean)=arch/x86/boot + +When "make clean" is executed, make will descend down in arch/x86/boot, +and clean as usual. The Makefile located in arch/x86/boot/ may use +the subdir- trick to descend further down. + +Note 1: arch/$(ARCH)/Makefile cannot use "subdir-", because that file is +included in the top level makefile, and the kbuild infrastructure +is not operational at that point. + +Note 2: All directories listed in core-y, libs-y, drivers-y and net-y will +be visited during "make clean". + +6 Architecture Makefiles +======================== + +The top level Makefile sets up the environment and does the preparation, +before starting to descend down in the individual directories. +The top level makefile contains the generic part, whereas +arch/$(ARCH)/Makefile contains what is required to set up kbuild +for said architecture. +To do so, arch/$(ARCH)/Makefile sets up a number of variables and defines +a few targets. + +When kbuild executes, the following steps are followed (roughly): + +1) Configuration of the kernel => produce .config +2) Store kernel version in include/linux/version.h +3) Updating all other prerequisites to the target prepare: + - Additional prerequisites are specified in arch/$(ARCH)/Makefile +4) Recursively descend down in all directories listed in + init-* core* drivers-* net-* libs-* and build all targets. + - The values of the above variables are expanded in arch/$(ARCH)/Makefile. +5) All object files are then linked and the resulting file vmlinux is + located at the root of the obj tree. + The very first objects linked are listed in head-y, assigned by + arch/$(ARCH)/Makefile. +6) Finally, the architecture-specific part does any required post processing + and builds the final bootimage. + - This includes building boot records + - Preparing initrd images and the like + + +6.1 Set variables to tweak the build to the architecture +-------------------------------------------------------- + + LDFLAGS + Generic $(LD) options + + Flags used for all invocations of the linker. + Often specifying the emulation is sufficient. + + Example:: + + #arch/s390/Makefile + LDFLAGS := -m elf_s390 + + Note: ldflags-y can be used to further customise + the flags used. See chapter 3.7. + + LDFLAGS_vmlinux + Options for $(LD) when linking vmlinux + + LDFLAGS_vmlinux is used to specify additional flags to pass to + the linker when linking the final vmlinux image. + LDFLAGS_vmlinux uses the LDFLAGS_$@ support. + + Example:: + + #arch/x86/Makefile + LDFLAGS_vmlinux := -e stext + + OBJCOPYFLAGS + objcopy flags + + When $(call if_changed,objcopy) is used to translate a .o file, + the flags specified in OBJCOPYFLAGS will be used. + $(call if_changed,objcopy) is often used to generate raw binaries on + vmlinux. + + Example:: + + #arch/s390/Makefile + OBJCOPYFLAGS := -O binary + + #arch/s390/boot/Makefile + $(obj)/image: vmlinux FORCE + $(call if_changed,objcopy) + + In this example, the binary $(obj)/image is a binary version of + vmlinux. The usage of $(call if_changed,xxx) will be described later. + + KBUILD_AFLAGS + $(AS) assembler flags + + Default value - see top level Makefile + Append or modify as required per architecture. + + Example:: + + #arch/sparc64/Makefile + KBUILD_AFLAGS += -m64 -mcpu=ultrasparc + + KBUILD_CFLAGS + $(CC) compiler flags + + Default value - see top level Makefile + Append or modify as required per architecture. + + Often, the KBUILD_CFLAGS variable depends on the configuration. + + Example:: + + #arch/x86/boot/compressed/Makefile + cflags-$(CONFIG_X86_32) := -march=i386 + cflags-$(CONFIG_X86_64) := -mcmodel=small + KBUILD_CFLAGS += $(cflags-y) + + Many arch Makefiles dynamically run the target C compiler to + probe supported options:: + + #arch/x86/Makefile + + ... + cflags-$(CONFIG_MPENTIUMII) += $(call cc-option,\ + -march=pentium2,-march=i686) + ... + # Disable unit-at-a-time mode ... + KBUILD_CFLAGS += $(call cc-option,-fno-unit-at-a-time) + ... + + + The first example utilises the trick that a config option expands + to 'y' when selected. + + KBUILD_AFLAGS_KERNEL + $(AS) options specific for built-in + + $(KBUILD_AFLAGS_KERNEL) contains extra C compiler flags used to compile + resident kernel code. + + KBUILD_AFLAGS_MODULE + Options for $(AS) when building modules + + $(KBUILD_AFLAGS_MODULE) is used to add arch-specific options that + are used for $(AS). + + From commandline AFLAGS_MODULE shall be used (see kbuild.txt). + + KBUILD_CFLAGS_KERNEL + $(CC) options specific for built-in + + $(KBUILD_CFLAGS_KERNEL) contains extra C compiler flags used to compile + resident kernel code. + + KBUILD_CFLAGS_MODULE + Options for $(CC) when building modules + + $(KBUILD_CFLAGS_MODULE) is used to add arch-specific options that + are used for $(CC). + From commandline CFLAGS_MODULE shall be used (see kbuild.txt). + + KBUILD_LDFLAGS_MODULE + Options for $(LD) when linking modules + + $(KBUILD_LDFLAGS_MODULE) is used to add arch-specific options + used when linking modules. This is often a linker script. + + From commandline LDFLAGS_MODULE shall be used (see kbuild.txt). + + KBUILD_ARFLAGS Options for $(AR) when creating archives + + $(KBUILD_ARFLAGS) set by the top level Makefile to "D" (deterministic + mode) if this option is supported by $(AR). + + ARCH_CPPFLAGS, ARCH_AFLAGS, ARCH_CFLAGS Overrides the kbuild defaults + + These variables are appended to the KBUILD_CPPFLAGS, + KBUILD_AFLAGS, and KBUILD_CFLAGS, respectively, after the + top-level Makefile has set any other flags. This provides a + means for an architecture to override the defaults. + + +6.2 Add prerequisites to archheaders +------------------------------------ + + The archheaders: rule is used to generate header files that + may be installed into user space by "make header_install" or + "make headers_install_all". In order to support + "make headers_install_all", this target has to be able to run + on an unconfigured tree, or a tree configured for another + architecture. + + It is run before "make archprepare" when run on the + architecture itself. + + +6.3 Add prerequisites to archprepare +------------------------------------ + + The archprepare: rule is used to list prerequisites that need to be + built before starting to descend down in the subdirectories. + This is usually used for header files containing assembler constants. + + Example:: + + #arch/arm/Makefile + archprepare: maketools + + In this example, the file target maketools will be processed + before descending down in the subdirectories. + See also chapter XXX-TODO that describe how kbuild supports + generating offset header files. + + +6.4 List directories to visit when descending +--------------------------------------------- + + An arch Makefile cooperates with the top Makefile to define variables + which specify how to build the vmlinux file. Note that there is no + corresponding arch-specific section for modules; the module-building + machinery is all architecture-independent. + + + head-y, init-y, core-y, libs-y, drivers-y, net-y + $(head-y) lists objects to be linked first in vmlinux. + + $(libs-y) lists directories where a lib.a archive can be located. + + The rest list directories where a built-in.a object file can be + located. + + $(init-y) objects will be located after $(head-y). + + Then the rest follows in this order: + + $(core-y), $(libs-y), $(drivers-y) and $(net-y). + + The top level Makefile defines values for all generic directories, + and arch/$(ARCH)/Makefile only adds architecture-specific + directories. + + Example:: + + #arch/sparc64/Makefile + core-y += arch/sparc64/kernel/ + libs-y += arch/sparc64/prom/ arch/sparc64/lib/ + drivers-$(CONFIG_OPROFILE) += arch/sparc64/oprofile/ + + +6.5 Architecture-specific boot images +------------------------------------- + + An arch Makefile specifies goals that take the vmlinux file, compress + it, wrap it in bootstrapping code, and copy the resulting files + somewhere. This includes various kinds of installation commands. + The actual goals are not standardized across architectures. + + It is common to locate any additional processing in a boot/ + directory below arch/$(ARCH)/. + + Kbuild does not provide any smart way to support building a + target specified in boot/. Therefore arch/$(ARCH)/Makefile shall + call make manually to build a target in boot/. + + The recommended approach is to include shortcuts in + arch/$(ARCH)/Makefile, and use the full path when calling down + into the arch/$(ARCH)/boot/Makefile. + + Example:: + + #arch/x86/Makefile + boot := arch/x86/boot + bzImage: vmlinux + $(Q)$(MAKE) $(build)=$(boot) $(boot)/$@ + + "$(Q)$(MAKE) $(build)=" is the recommended way to invoke + make in a subdirectory. + + There are no rules for naming architecture-specific targets, + but executing "make help" will list all relevant targets. + To support this, $(archhelp) must be defined. + + Example:: + + #arch/x86/Makefile + define archhelp + echo '* bzImage - Image (arch/$(ARCH)/boot/bzImage)' + endif + + When make is executed without arguments, the first goal encountered + will be built. In the top level Makefile the first goal present + is all:. + An architecture shall always, per default, build a bootable image. + In "make help", the default goal is highlighted with a '*'. + Add a new prerequisite to all: to select a default goal different + from vmlinux. + + Example:: + + #arch/x86/Makefile + all: bzImage + + When "make" is executed without arguments, bzImage will be built. + +6.6 Building non-kbuild targets +------------------------------- + + extra-y + extra-y specifies additional targets created in the current + directory, in addition to any targets specified by `obj-*`. + + Listing all targets in extra-y is required for two purposes: + + 1) Enable kbuild to check changes in command lines + + - When $(call if_changed,xxx) is used + + 2) kbuild knows what files to delete during "make clean" + + Example:: + + #arch/x86/kernel/Makefile + extra-y := head.o init_task.o + + In this example, extra-y is used to list object files that + shall be built, but shall not be linked as part of built-in.a. + + +6.7 Commands useful for building a boot image +--------------------------------------------- + + Kbuild provides a few macros that are useful when building a + boot image. + + if_changed + if_changed is the infrastructure used for the following commands. + + Usage:: + + target: source(s) FORCE + $(call if_changed,ld/objcopy/gzip/...) + + When the rule is evaluated, it is checked to see if any files + need an update, or the command line has changed since the last + invocation. The latter will force a rebuild if any options + to the executable have changed. + Any target that utilises if_changed must be listed in $(targets), + otherwise the command line check will fail, and the target will + always be built. + Assignments to $(targets) are without $(obj)/ prefix. + if_changed may be used in conjunction with custom commands as + defined in 6.8 "Custom kbuild commands". + + Note: It is a typical mistake to forget the FORCE prerequisite. + Another common pitfall is that whitespace is sometimes + significant; for instance, the below will fail (note the extra space + after the comma):: + + target: source(s) FORCE + + **WRONG!** $(call if_changed, ld/objcopy/gzip/...) + + Note: + if_changed should not be used more than once per target. + It stores the executed command in a corresponding .cmd + + file and multiple calls would result in overwrites and + unwanted results when the target is up to date and only the + tests on changed commands trigger execution of commands. + + ld + Link target. Often, LDFLAGS_$@ is used to set specific options to ld. + + Example:: + + #arch/x86/boot/Makefile + LDFLAGS_bootsect := -Ttext 0x0 -s --oformat binary + LDFLAGS_setup := -Ttext 0x0 -s --oformat binary -e begtext + + targets += setup setup.o bootsect bootsect.o + $(obj)/setup $(obj)/bootsect: %: %.o FORCE + $(call if_changed,ld) + + In this example, there are two possible targets, requiring different + options to the linker. The linker options are specified using the + LDFLAGS_$@ syntax - one for each potential target. + $(targets) are assigned all potential targets, by which kbuild knows + the targets and will: + + 1) check for commandline changes + 2) delete target during make clean + + The ": %: %.o" part of the prerequisite is a shorthand that + frees us from listing the setup.o and bootsect.o files. + + Note: + It is a common mistake to forget the "targets :=" assignment, + resulting in the target file being recompiled for no + obvious reason. + + objcopy + Copy binary. Uses OBJCOPYFLAGS usually specified in + arch/$(ARCH)/Makefile. + OBJCOPYFLAGS_$@ may be used to set additional options. + + gzip + Compress target. Use maximum compression to compress target. + + Example:: + + #arch/x86/boot/compressed/Makefile + $(obj)/vmlinux.bin.gz: $(vmlinux.bin.all-y) FORCE + $(call if_changed,gzip) + + dtc + Create flattened device tree blob object suitable for linking + into vmlinux. Device tree blobs linked into vmlinux are placed + in an init section in the image. Platform code *must* copy the + blob to non-init memory prior to calling unflatten_device_tree(). + + To use this command, simply add `*.dtb` into obj-y or targets, or make + some other target depend on `%.dtb` + + A central rule exists to create `$(obj)/%.dtb` from `$(src)/%.dts`; + architecture Makefiles do no need to explicitly write out that rule. + + Example:: + + targets += $(dtb-y) + DTC_FLAGS ?= -p 1024 + +6.8 Custom kbuild commands +-------------------------- + + When kbuild is executing with KBUILD_VERBOSE=0, then only a shorthand + of a command is normally displayed. + To enable this behaviour for custom commands kbuild requires + two variables to be set:: + + quiet_cmd_ - what shall be echoed + cmd_ - the command to execute + + Example:: + + # + quiet_cmd_image = BUILD $@ + cmd_image = $(obj)/tools/build $(BUILDFLAGS) \ + $(obj)/vmlinux.bin > $@ + + targets += bzImage + $(obj)/bzImage: $(obj)/vmlinux.bin $(obj)/tools/build FORCE + $(call if_changed,image) + @echo 'Kernel: $@ is ready' + + When updating the $(obj)/bzImage target, the line: + + BUILD arch/x86/boot/bzImage + + will be displayed with "make KBUILD_VERBOSE=0". + + +--- 6.9 Preprocessing linker scripts + + When the vmlinux image is built, the linker script + arch/$(ARCH)/kernel/vmlinux.lds is used. + The script is a preprocessed variant of the file vmlinux.lds.S + located in the same directory. + kbuild knows .lds files and includes a rule `*lds.S` -> `*lds`. + + Example:: + + #arch/x86/kernel/Makefile + always := vmlinux.lds + + #Makefile + export CPPFLAGS_vmlinux.lds += -P -C -U$(ARCH) + + The assignment to $(always) is used to tell kbuild to build the + target vmlinux.lds. + The assignment to $(CPPFLAGS_vmlinux.lds) tells kbuild to use the + specified options when building the target vmlinux.lds. + + When building the `*.lds` target, kbuild uses the variables:: + + KBUILD_CPPFLAGS : Set in top-level Makefile + cppflags-y : May be set in the kbuild makefile + CPPFLAGS_$(@F) : Target-specific flags. + Note that the full filename is used in this + assignment. + + The kbuild infrastructure for `*lds` files is used in several + architecture-specific files. + +6.10 Generic header files +------------------------- + + The directory include/asm-generic contains the header files + that may be shared between individual architectures. + The recommended approach how to use a generic header file is + to list the file in the Kbuild file. + See "7.2 generic-y" for further info on syntax etc. + +6.11 Post-link pass +------------------- + + If the file arch/xxx/Makefile.postlink exists, this makefile + will be invoked for post-link objects (vmlinux and modules.ko) + for architectures to run post-link passes on. Must also handle + the clean target. + + This pass runs after kallsyms generation. If the architecture + needs to modify symbol locations, rather than manipulate the + kallsyms, it may be easier to add another postlink target for + .tmp_vmlinux? targets to be called from link-vmlinux.sh. + + For example, powerpc uses this to check relocation sanity of + the linked vmlinux file. + +7 Kbuild syntax for exported headers +------------------------------------ + +The kernel includes a set of headers that is exported to userspace. +Many headers can be exported as-is but other headers require a +minimal pre-processing before they are ready for user-space. +The pre-processing does: + +- drop kernel-specific annotations +- drop include of compiler.h +- drop all sections that are kernel internal (guarded by `ifdef __KERNEL__`) + +All headers under include/uapi/, include/generated/uapi/, +arch//include/uapi/ and arch//include/generated/uapi/ +are exported. + +A Kbuild file may be defined under arch//include/uapi/asm/ and +arch//include/asm/ to list asm files coming from asm-generic. +See subsequent chapter for the syntax of the Kbuild file. + +7.1 no-export-headers +--------------------- + + no-export-headers is essentially used by include/uapi/linux/Kbuild to + avoid exporting specific headers (e.g. kvm.h) on architectures that do + not support it. It should be avoided as much as possible. + +7.2 generic-y +------------- + + If an architecture uses a verbatim copy of a header from + include/asm-generic then this is listed in the file + arch/$(ARCH)/include/asm/Kbuild like this: + + Example:: + + #arch/x86/include/asm/Kbuild + generic-y += termios.h + generic-y += rtc.h + + During the prepare phase of the build a wrapper include + file is generated in the directory:: + + arch/$(ARCH)/include/generated/asm + + When a header is exported where the architecture uses + the generic header a similar wrapper is generated as part + of the set of exported headers in the directory:: + + usr/include/asm + + The generated wrapper will in both cases look like the following: + + Example: termios.h:: + + #include + +7.3 generated-y +--------------- + + If an architecture generates other header files alongside generic-y + wrappers, generated-y specifies them. + + This prevents them being treated as stale asm-generic wrappers and + removed. + + Example:: + + #arch/x86/include/asm/Kbuild + generated-y += syscalls_32.h + +7.4 mandatory-y +--------------- + + mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild + to define the minimum set of ASM headers that all architectures must have. + + This works like optional generic-y. If a mandatory header is missing + in arch/$(ARCH)/include/(uapi/)/asm, Kbuild will automatically generate + a wrapper of the asm-generic one. + + The convention is to list one subdir per line and + preferably in alphabetic order. + +8 Kbuild Variables +================== + +The top Makefile exports the following variables: + + VERSION, PATCHLEVEL, SUBLEVEL, EXTRAVERSION + These variables define the current kernel version. A few arch + Makefiles actually use these values directly; they should use + $(KERNELRELEASE) instead. + + $(VERSION), $(PATCHLEVEL), and $(SUBLEVEL) define the basic + three-part version number, such as "2", "4", and "0". These three + values are always numeric. + + $(EXTRAVERSION) defines an even tinier sublevel for pre-patches + or additional patches. It is usually some non-numeric string + such as "-pre4", and is often blank. + + KERNELRELEASE + $(KERNELRELEASE) is a single string such as "2.4.0-pre4", suitable + for constructing installation directory names or showing in + version strings. Some arch Makefiles use it for this purpose. + + ARCH + This variable defines the target architecture, such as "i386", + "arm", or "sparc". Some kbuild Makefiles test $(ARCH) to + determine which files to compile. + + By default, the top Makefile sets $(ARCH) to be the same as the + host system architecture. For a cross build, a user may + override the value of $(ARCH) on the command line:: + + make ARCH=m68k ... + + + INSTALL_PATH + This variable defines a place for the arch Makefiles to install + the resident kernel image and System.map file. + Use this for architecture-specific install targets. + + INSTALL_MOD_PATH, MODLIB + $(INSTALL_MOD_PATH) specifies a prefix to $(MODLIB) for module + installation. This variable is not defined in the Makefile but + may be passed in by the user if desired. + + $(MODLIB) specifies the directory for module installation. + The top Makefile defines $(MODLIB) to + $(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE). The user may + override this value on the command line if desired. + + INSTALL_MOD_STRIP + If this variable is specified, it will cause modules to be stripped + after they are installed. If INSTALL_MOD_STRIP is '1', then the + default option --strip-debug will be used. Otherwise, the + INSTALL_MOD_STRIP value will be used as the option(s) to the strip + command. + + +9 Makefile language +=================== + +The kernel Makefiles are designed to be run with GNU Make. The Makefiles +use only the documented features of GNU Make, but they do use many +GNU extensions. + +GNU Make supports elementary list-processing functions. The kernel +Makefiles use a novel style of list building and manipulation with few +"if" statements. + +GNU Make has two assignment operators, ":=" and "=". ":=" performs +immediate evaluation of the right-hand side and stores an actual string +into the left-hand side. "=" is like a formula definition; it stores the +right-hand side in an unevaluated form and then evaluates this form each +time the left-hand side is used. + +There are some cases where "=" is appropriate. Usually, though, ":=" +is the right choice. + +10 Credits +========== + +- Original version made by Michael Elizabeth Chastain, +- Updates by Kai Germaschewski +- Updates by Sam Ravnborg +- Language QA by Jan Engelhardt + +11 TODO +======= + +- Describe how kbuild supports shipped files with _shipped. +- Generating offset header files. +- Add more variables to section 7? diff --git a/Documentation/kbuild/makefiles.txt b/Documentation/kbuild/makefiles.txt deleted file mode 100644 index d65ad5746f94..000000000000 --- a/Documentation/kbuild/makefiles.txt +++ /dev/null @@ -1,1369 +0,0 @@ -Linux Kernel Makefiles - -This document describes the Linux kernel Makefiles. - -=== Table of Contents - - === 1 Overview - === 2 Who does what - === 3 The kbuild files - --- 3.1 Goal definitions - --- 3.2 Built-in object goals - obj-y - --- 3.3 Loadable module goals - obj-m - --- 3.4 Objects which export symbols - --- 3.5 Library file goals - lib-y - --- 3.6 Descending down in directories - --- 3.7 Compilation flags - --- 3.8 Command line dependency - --- 3.9 Dependency tracking - --- 3.10 Special Rules - --- 3.11 $(CC) support functions - --- 3.12 $(LD) support functions - - === 4 Host Program support - --- 4.1 Simple Host Program - --- 4.2 Composite Host Programs - --- 4.3 Using C++ for host programs - --- 4.4 Controlling compiler options for host programs - --- 4.5 When host programs are actually built - --- 4.6 Using hostprogs-$(CONFIG_FOO) - - === 5 Kbuild clean infrastructure - - === 6 Architecture Makefiles - --- 6.1 Set variables to tweak the build to the architecture - --- 6.2 Add prerequisites to archheaders: - --- 6.3 Add prerequisites to archprepare: - --- 6.4 List directories to visit when descending - --- 6.5 Architecture-specific boot images - --- 6.6 Building non-kbuild targets - --- 6.7 Commands useful for building a boot image - --- 6.8 Custom kbuild commands - --- 6.9 Preprocessing linker scripts - --- 6.10 Generic header files - --- 6.11 Post-link pass - - === 7 Kbuild syntax for exported headers - --- 7.1 no-export-headers - --- 7.2 generic-y - --- 7.3 generated-y - --- 7.4 mandatory-y - - === 8 Kbuild Variables - === 9 Makefile language - === 10 Credits - === 11 TODO - -=== 1 Overview - -The Makefiles have five parts: - - Makefile the top Makefile. - .config the kernel configuration file. - arch/$(ARCH)/Makefile the arch Makefile. - scripts/Makefile.* common rules etc. for all kbuild Makefiles. - kbuild Makefiles there are about 500 of these. - -The top Makefile reads the .config file, which comes from the kernel -configuration process. - -The top Makefile is responsible for building two major products: vmlinux -(the resident kernel image) and modules (any module files). -It builds these goals by recursively descending into the subdirectories of -the kernel source tree. -The list of subdirectories which are visited depends upon the kernel -configuration.

They usually do not read or edit -any kernel Makefiles (or any other source files). - -*Normal developers* are people who work on features such as device -drivers, file systems, and network protocols. These people need to -maintain the kbuild Makefiles for the subsystem they are -working on. In order to do this effectively, they need some overall -knowledge about the kernel Makefiles, plus detailed knowledge about the -public interface for kbuild. - -*Arch developers* are people who work on an entire architecture, such -as sparc or ia64. Arch developers need to know about the arch Makefile -as well as kbuild Makefiles. - -*Kbuild developers* are people who work on the kernel build system itself. -These people need to know about all aspects of the kernel Makefiles. - -This document is aimed towards normal developers and arch developers. - - -=== 3 The kbuild files - -Most Makefiles within the kernel are kbuild Makefiles that use the -kbuild infrastructure. This chapter introduces the syntax used in the -kbuild makefiles. -The preferred name for the kbuild files are 'Makefile' but 'Kbuild' can -be used and if both a 'Makefile' and a 'Kbuild' file exists, then the 'Kbuild' -file will be used. - -Section 3.1 "Goal definitions" is a quick intro, further chapters provide -more details, with real examples. - ---- 3.1 Goal definitions - - Goal definitions are the main part (heart) of the kbuild Makefile. - These lines define the files to be built, any special compilation - options, and any subdirectories to be entered recursively. - - The most simple kbuild makefile contains one line: - - Example: - obj-y += foo.o - - This tells kbuild that there is one object in that directory, named - foo.o. foo.o will be built from foo.c or foo.S. - - If foo.o shall be built as a module, the variable obj-m is used. - Therefore the following pattern is often used: - - Example: - obj-$(CONFIG_FOO) += foo.o - - $(CONFIG_FOO) evaluates to either y (for built-in) or m (for module). - If CONFIG_FOO is neither y nor m, then the file will not be compiled - nor linked. - ---- 3.2 Built-in object goals - obj-y - - The kbuild Makefile specifies object files for vmlinux - in the $(obj-y) lists. These lists depend on the kernel - configuration. - - Kbuild compiles all the $(obj-y) files. It then calls - "$(AR) rcSTP" to merge these files into one built-in.a file. - This is a thin archive without a symbol table. It will be later - linked into vmlinux by scripts/link-vmlinux.sh - - The order of files in $(obj-y) is significant. Duplicates in - the lists are allowed: the first instance will be linked into - built-in.a and succeeding instances will be ignored. - - Link order is significant, because certain functions - (module_init() / __initcall) will be called during boot in the - order they appear. So keep in mind that changing the link - order may e.g. change the order in which your SCSI - controllers are detected, and thus your disks are renumbered. - - Example: - #drivers/isdn/i4l/Makefile - # Makefile for the kernel ISDN subsystem and device drivers. - # Each configuration option enables a list of files. - obj-$(CONFIG_ISDN_I4L) += isdn.o - obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o - ---- 3.3 Loadable module goals - obj-m - - $(obj-m) specifies object files which are built as loadable - kernel modules. - - A module may be built from one source file or several source - files. In the case of one source file, the kbuild makefile - simply adds the file to $(obj-m). - - Example: - #drivers/isdn/i4l/Makefile - obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o - - Note: In this example $(CONFIG_ISDN_PPP_BSDCOMP) evaluates to 'm' - - If a kernel module is built from several source files, you specify - that you want to build a module in the same way as above; however, - kbuild needs to know which object files you want to build your - module from, so you have to tell it by setting a $(-y) - variable. - - Example: - #drivers/isdn/i4l/Makefile - obj-$(CONFIG_ISDN_I4L) += isdn.o - isdn-y := isdn_net_lib.o isdn_v110.o isdn_common.o - - In this example, the module name will be isdn.o. Kbuild will - compile the objects listed in $(isdn-y) and then run - "$(LD) -r" on the list of these files to generate isdn.o. - - Due to kbuild recognizing $(-y) for composite objects, - you can use the value of a CONFIG_ symbol to optionally include an - object file as part of a composite object. - - Example: - #fs/ext2/Makefile - obj-$(CONFIG_EXT2_FS) += ext2.o - ext2-y := balloc.o dir.o file.o ialloc.o inode.o ioctl.o \ - namei.o super.o symlink.o - ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o xattr_user.o \ - xattr_trusted.o - - In this example, xattr.o, xattr_user.o and xattr_trusted.o are only - part of the composite object ext2.o if $(CONFIG_EXT2_FS_XATTR) - evaluates to 'y'. - - Note: Of course, when you are building objects into the kernel, - the syntax above will also work. So, if you have CONFIG_EXT2_FS=y, - kbuild will build an ext2.o file for you out of the individual - parts and then link this into built-in.a, as you would expect. - ---- 3.4 Objects which export symbols - - No special notation is required in the makefiles for - modules exporting symbols. - ---- 3.5 Library file goals - lib-y - - Objects listed with obj-* are used for modules, or - combined in a built-in.a for that specific directory. - There is also the possibility to list objects that will - be included in a library, lib.a. - All objects listed with lib-y are combined in a single - library for that directory. - Objects that are listed in obj-y and additionally listed in - lib-y will not be included in the library, since they will - be accessible anyway. - For consistency, objects listed in lib-m will be included in lib.a. - - Note that the same kbuild makefile may list files to be built-in - and to be part of a library. Therefore the same directory - may contain both a built-in.a and a lib.a file. - - Example: - #arch/x86/lib/Makefile - lib-y := delay.o - - This will create a library lib.a based on delay.o. For kbuild to - actually recognize that there is a lib.a being built, the directory - shall be listed in libs-y. - See also "6.4 List directories to visit when descending". - - Use of lib-y is normally restricted to lib/ and arch/*/lib. - ---- 3.6 Descending down in directories - - A Makefile is only responsible for building objects in its own - directory. Files in subdirectories should be taken care of by - Makefiles in these subdirs. The build system will automatically - invoke make recursively in subdirectories, provided you let it know of - them. - - To do so, obj-y and obj-m are used. - ext2 lives in a separate directory, and the Makefile present in fs/ - tells kbuild to descend down using the following assignment. - - Example: - #fs/Makefile - obj-$(CONFIG_EXT2_FS) += ext2/ - - If CONFIG_EXT2_FS is set to either 'y' (built-in) or 'm' (modular) - the corresponding obj- variable will be set, and kbuild will descend - down in the ext2 directory. - Kbuild only uses this information to decide that it needs to visit - the directory, it is the Makefile in the subdirectory that - specifies what is modular and what is built-in. - - It is good practice to use a CONFIG_ variable when assigning directory - names. This allows kbuild to totally skip the directory if the - corresponding CONFIG_ option is neither 'y' nor 'm'. - ---- 3.7 Compilation flags - - ccflags-y, asflags-y and ldflags-y - These three flags apply only to the kbuild makefile in which they - are assigned. They are used for all the normal cc, as and ld - invocations happening during a recursive build. - Note: Flags with the same behaviour were previously named: - EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS. - They are still supported but their usage is deprecated. - - ccflags-y specifies options for compiling with $(CC). - - Example: - # drivers/acpi/acpica/Makefile - ccflags-y := -Os -D_LINUX -DBUILDING_ACPICA - ccflags-$(CONFIG_ACPI_DEBUG) += -DACPI_DEBUG_OUTPUT - - This variable is necessary because the top Makefile owns the - variable $(KBUILD_CFLAGS) and uses it for compilation flags for the - entire tree. - - asflags-y specifies options for assembling with $(AS). - - Example: - #arch/sparc/kernel/Makefile - asflags-y := -ansi - - ldflags-y specifies options for linking with $(LD). - - Example: - #arch/cris/boot/compressed/Makefile - ldflags-y += -T $(srctree)/$(src)/decompress_$(arch-y).lds - - subdir-ccflags-y, subdir-asflags-y - The two flags listed above are similar to ccflags-y and asflags-y. - The difference is that the subdir- variants have effect for the kbuild - file where they are present and all subdirectories. - Options specified using subdir-* are added to the commandline before - the options specified using the non-subdir variants. - - Example: - subdir-ccflags-y := -Werror - - CFLAGS_$@, AFLAGS_$@ - - CFLAGS_$@ and AFLAGS_$@ only apply to commands in current - kbuild makefile. - - $(CFLAGS_$@) specifies per-file options for $(CC). The $@ - part has a literal value which specifies the file that it is for. - - Example: - # drivers/scsi/Makefile - CFLAGS_aha152x.o = -DAHA152X_STAT -DAUTOCONF - CFLAGS_gdth.o = # -DDEBUG_GDTH=2 -D__SERIAL__ -D__COM2__ \ - -DGDTH_STATISTICS - - These two lines specify compilation flags for aha152x.o and gdth.o. - - $(AFLAGS_$@) is a similar feature for source files in assembly - languages. - - Example: - # arch/arm/kernel/Makefile - AFLAGS_head.o := -DTEXT_OFFSET=$(TEXT_OFFSET) - AFLAGS_crunch-bits.o := -Wa,-mcpu=ep9312 - AFLAGS_iwmmxt.o := -Wa,-mcpu=iwmmxt - - ---- 3.9 Dependency tracking - - Kbuild tracks dependencies on the following: - 1) All prerequisite files (both *.c and *.h) - 2) CONFIG_ options used in all prerequisite files - 3) Command-line used to compile target - - Thus, if you change an option to $(CC) all affected files will - be re-compiled. - ---- 3.10 Special Rules - - Special rules are used when the kbuild infrastructure does - not provide the required support. A typical example is - header files generated during the build process. - Another example are the architecture-specific Makefiles which - need special rules to prepare boot images etc. - - Special rules are written as normal Make rules. - Kbuild is not executing in the directory where the Makefile is - located, so all special rules shall provide a relative - path to prerequisite files and target files. - - Two variables are used when defining special rules: - - $(src) - $(src) is a relative path which points to the directory - where the Makefile is located. Always use $(src) when - referring to files located in the src tree. - - $(obj) - $(obj) is a relative path which points to the directory - where the target is saved. Always use $(obj) when - referring to generated files. - - Example: - #drivers/scsi/Makefile - $(obj)/53c8xx_d.h: $(src)/53c7,8xx.scr $(src)/script_asm.pl - $(CPP) -DCHIP=810 - < $< | ... $(src)/script_asm.pl - - This is a special rule, following the normal syntax - required by make. - The target file depends on two prerequisite files. References - to the target file are prefixed with $(obj), references - to prerequisites are referenced with $(src) (because they are not - generated files). - - $(kecho) - echoing information to user in a rule is often a good practice - but when execution "make -s" one does not expect to see any output - except for warnings/errors. - To support this kbuild defines $(kecho) which will echo out the - text following $(kecho) to stdout except if "make -s" is used. - - Example: - #arch/blackfin/boot/Makefile - $(obj)/vmImage: $(obj)/vmlinux.gz - $(call if_changed,uimage) - @$(kecho) 'Kernel: $@ is ready' - - ---- 3.11 $(CC) support functions - - The kernel may be built with several different versions of - $(CC), each supporting a unique set of features and options. - kbuild provides basic support to check for valid options for $(CC). - $(CC) is usually the gcc compiler, but other alternatives are - available. - - as-option - as-option is used to check if $(CC) -- when used to compile - assembler (*.S) files -- supports the given option. An optional - second option may be specified if the first option is not supported. - - Example: - #arch/sh/Makefile - cflags-y += $(call as-option,-Wa$(comma)-isa=$(isa-y),) - - In the above example, cflags-y will be assigned the option - -Wa$(comma)-isa=$(isa-y) if it is supported by $(CC). - The second argument is optional, and if supplied will be used - if first argument is not supported. - - as-instr - as-instr checks if the assembler reports a specific instruction - and then outputs either option1 or option2 - C escapes are supported in the test instruction - Note: as-instr-option uses KBUILD_AFLAGS for $(AS) options - - cc-option - cc-option is used to check if $(CC) supports a given option, and if - not supported to use an optional second option. - - Example: - #arch/x86/Makefile - cflags-y += $(call cc-option,-march=pentium-mmx,-march=i586) - - In the above example, cflags-y will be assigned the option - -march=pentium-mmx if supported by $(CC), otherwise -march=i586. - The second argument to cc-option is optional, and if omitted, - cflags-y will be assigned no value if first option is not supported. - Note: cc-option uses KBUILD_CFLAGS for $(CC) options - - cc-option-yn - cc-option-yn is used to check if gcc supports a given option - and return 'y' if supported, otherwise 'n'. - - Example: - #arch/ppc/Makefile - biarch := $(call cc-option-yn, -m32) - aflags-$(biarch) += -a32 - cflags-$(biarch) += -m32 - - In the above example, $(biarch) is set to y if $(CC) supports the -m32 - option. When $(biarch) equals 'y', the expanded variables $(aflags-y) - and $(cflags-y) will be assigned the values -a32 and -m32, - respectively. - Note: cc-option-yn uses KBUILD_CFLAGS for $(CC) options - - cc-disable-warning - cc-disable-warning checks if gcc supports a given warning and returns - the commandline switch to disable it. This special function is needed, - because gcc 4.4 and later accept any unknown -Wno-* option and only - warn about it if there is another warning in the source file. - - Example: - KBUILD_CFLAGS += $(call cc-disable-warning, unused-but-set-variable) - - In the above example, -Wno-unused-but-set-variable will be added to - KBUILD_CFLAGS only if gcc really accepts it. - - cc-ifversion - cc-ifversion tests the version of $(CC) and equals the fourth parameter - if version expression is true, or the fifth (if given) if the version - expression is false. - - Example: - #fs/reiserfs/Makefile - ccflags-y := $(call cc-ifversion, -lt, 0402, -O1) - - In this example, ccflags-y will be assigned the value -O1 if the - $(CC) version is less than 4.2. - cc-ifversion takes all the shell operators: - -eq, -ne, -lt, -le, -gt, and -ge - The third parameter may be a text as in this example, but it may also - be an expanded variable or a macro. - - cc-cross-prefix - cc-cross-prefix is used to check if there exists a $(CC) in path with - one of the listed prefixes. The first prefix where there exist a - prefix$(CC) in the PATH is returned - and if no prefix$(CC) is found - then nothing is returned. - Additional prefixes are separated by a single space in the - call of cc-cross-prefix. - This functionality is useful for architecture Makefiles that try - to set CROSS_COMPILE to well-known values but may have several - values to select between. - It is recommended only to try to set CROSS_COMPILE if it is a cross - build (host arch is different from target arch). And if CROSS_COMPILE - is already set then leave it with the old value. - - Example: - #arch/m68k/Makefile - ifneq ($(SUBARCH),$(ARCH)) - ifeq ($(CROSS_COMPILE),) - CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu-) - endif - endif - ---- 3.12 $(LD) support functions - - ld-option - ld-option is used to check if $(LD) supports the supplied option. - ld-option takes two options as arguments. - The second argument is an optional option that can be used if the - first option is not supported by $(LD). - - Example: - #Makefile - LDFLAGS_vmlinux += $(call ld-option, -X) - - -=== 4 Host Program support - -Kbuild supports building executables on the host for use during the -compilation stage. -Two steps are required in order to use a host executable. - -The first step is to tell kbuild that a host program exists. This is -done utilising the variable hostprogs-y. - -The second step is to add an explicit dependency to the executable. -This can be done in two ways. Either add the dependency in a rule, -or utilise the variable $(always). -Both possibilities are described in the following. - ---- 4.1 Simple Host Program - - In some cases there is a need to compile and run a program on the - computer where the build is running. - The following line tells kbuild that the program bin2hex shall be - built on the build host. - - Example: - hostprogs-y := bin2hex - - Kbuild assumes in the above example that bin2hex is made from a single - c-source file named bin2hex.c located in the same directory as - the Makefile. - ---- 4.2 Composite Host Programs - - Host programs can be made up based on composite objects. - The syntax used to define composite objects for host programs is - similar to the syntax used for kernel objects. - $(-objs) lists all objects used to link the final - executable. - - Example: - #scripts/lxdialog/Makefile - hostprogs-y := lxdialog - lxdialog-objs := checklist.o lxdialog.o - - Objects with extension .o are compiled from the corresponding .c - files. In the above example, checklist.c is compiled to checklist.o - and lxdialog.c is compiled to lxdialog.o. - Finally, the two .o files are linked to the executable, lxdialog. - Note: The syntax -y is not permitted for host-programs. - ---- 4.3 Using C++ for host programs - - kbuild offers support for host programs written in C++. This was - introduced solely to support kconfig, and is not recommended - for general use. - - Example: - #scripts/kconfig/Makefile - hostprogs-y := qconf - qconf-cxxobjs := qconf.o - - In the example above the executable is composed of the C++ file - qconf.cc - identified by $(qconf-cxxobjs). - - If qconf is composed of a mixture of .c and .cc files, then an - additional line can be used to identify this. - - Example: - #scripts/kconfig/Makefile - hostprogs-y := qconf - qconf-cxxobjs := qconf.o - qconf-objs := check.o - ---- 4.4 Controlling compiler options for host programs - - When compiling host programs, it is possible to set specific flags. - The programs will always be compiled utilising $(HOSTCC) passed - the options specified in $(KBUILD_HOSTCFLAGS). - To set flags that will take effect for all host programs created - in that Makefile, use the variable HOST_EXTRACFLAGS. - - Example: - #scripts/lxdialog/Makefile - HOST_EXTRACFLAGS += -I/usr/include/ncurses - - To set specific flags for a single file the following construction - is used: - - Example: - #arch/ppc64/boot/Makefile - HOSTCFLAGS_piggyback.o := -DKERNELBASE=$(KERNELBASE) - - It is also possible to specify additional options to the linker. - - Example: - #scripts/kconfig/Makefile - HOSTLDLIBS_qconf := -L$(QTDIR)/lib - - When linking qconf, it will be passed the extra option - "-L$(QTDIR)/lib". - ---- 4.5 When host programs are actually built - - Kbuild will only build host-programs when they are referenced - as a prerequisite. - This is possible in two ways: - - (1) List the prerequisite explicitly in a special rule. - - Example: - #drivers/pci/Makefile - hostprogs-y := gen-devlist - $(obj)/devlist.h: $(src)/pci.ids $(obj)/gen-devlist - ( cd $(obj); ./gen-devlist ) < $< - - The target $(obj)/devlist.h will not be built before - $(obj)/gen-devlist is updated. Note that references to - the host programs in special rules must be prefixed with $(obj). - - (2) Use $(always) - When there is no suitable special rule, and the host program - shall be built when a makefile is entered, the $(always) - variable shall be used. - - Example: - #scripts/lxdialog/Makefile - hostprogs-y := lxdialog - always := $(hostprogs-y) - - This will tell kbuild to build lxdialog even if not referenced in - any rule. - ---- 4.6 Using hostprogs-$(CONFIG_FOO) - - A typical pattern in a Kbuild file looks like this: - - Example: - #scripts/Makefile - hostprogs-$(CONFIG_KALLSYMS) += kallsyms - - Kbuild knows about both 'y' for built-in and 'm' for module. - So if a config symbol evaluates to 'm', kbuild will still build - the binary. In other words, Kbuild handles hostprogs-m exactly - like hostprogs-y. But only hostprogs-y is recommended to be used - when no CONFIG symbols are involved. - -=== 5 Kbuild clean infrastructure - -"make clean" deletes most generated files in the obj tree where the kernel -is compiled. This includes generated files such as host programs. -Kbuild knows targets listed in $(hostprogs-y), $(hostprogs-m), $(always), -$(extra-y) and $(targets). They are all deleted during "make clean". -Files matching the patterns "*.[oas]", "*.ko", plus some additional files -generated by kbuild are deleted all over the kernel src tree when -"make clean" is executed. - -Additional files can be specified in kbuild makefiles by use of $(clean-files). - - Example: - #lib/Makefile - clean-files := crc32table.h - -When executing "make clean", the file "crc32table.h" will be deleted. -Kbuild will assume files to be in the same relative directory as the -Makefile, except if prefixed with $(objtree). - -To delete a directory hierarchy use: - - Example: - #scripts/package/Makefile - clean-dirs := $(objtree)/debian/ - -This will delete the directory debian in the toplevel directory, including all -subdirectories. - -To exclude certain files from make clean, use the $(no-clean-files) variable. -This is only a special case used in the top level Kbuild file: - - Example: - #Kbuild - no-clean-files := $(bounds-file) $(offsets-file) - -Usually kbuild descends down in subdirectories due to "obj-* := dir/", -but in the architecture makefiles where the kbuild infrastructure -is not sufficient this sometimes needs to be explicit. - - Example: - #arch/x86/boot/Makefile - subdir- := compressed/ - -The above assignment instructs kbuild to descend down in the -directory compressed/ when "make clean" is executed. - -To support the clean infrastructure in the Makefiles that build the -final bootimage there is an optional target named archclean: - - Example: - #arch/x86/Makefile - archclean: - $(Q)$(MAKE) $(clean)=arch/x86/boot - -When "make clean" is executed, make will descend down in arch/x86/boot, -and clean as usual. The Makefile located in arch/x86/boot/ may use -the subdir- trick to descend further down. - -Note 1: arch/$(ARCH)/Makefile cannot use "subdir-", because that file is -included in the top level makefile, and the kbuild infrastructure -is not operational at that point. - -Note 2: All directories listed in core-y, libs-y, drivers-y and net-y will -be visited during "make clean". - -=== 6 Architecture Makefiles - -The top level Makefile sets up the environment and does the preparation, -before starting to descend down in the individual directories. -The top level makefile contains the generic part, whereas -arch/$(ARCH)/Makefile contains what is required to set up kbuild -for said architecture. -To do so, arch/$(ARCH)/Makefile sets up a number of variables and defines -a few targets. - -When kbuild executes, the following steps are followed (roughly): -1) Configuration of the kernel => produce .config -2) Store kernel version in include/linux/version.h -3) Updating all other prerequisites to the target prepare: - - Additional prerequisites are specified in arch/$(ARCH)/Makefile -4) Recursively descend down in all directories listed in - init-* core* drivers-* net-* libs-* and build all targets. - - The values of the above variables are expanded in arch/$(ARCH)/Makefile. -5) All object files are then linked and the resulting file vmlinux is - located at the root of the obj tree. - The very first objects linked are listed in head-y, assigned by - arch/$(ARCH)/Makefile. -6) Finally, the architecture-specific part does any required post processing - and builds the final bootimage. - - This includes building boot records - - Preparing initrd images and the like - - ---- 6.1 Set variables to tweak the build to the architecture - - LDFLAGS Generic $(LD) options - - Flags used for all invocations of the linker. - Often specifying the emulation is sufficient. - - Example: - #arch/s390/Makefile - LDFLAGS := -m elf_s390 - Note: ldflags-y can be used to further customise - the flags used. See chapter 3.7. - - LDFLAGS_vmlinux Options for $(LD) when linking vmlinux - - LDFLAGS_vmlinux is used to specify additional flags to pass to - the linker when linking the final vmlinux image. - LDFLAGS_vmlinux uses the LDFLAGS_$@ support. - - Example: - #arch/x86/Makefile - LDFLAGS_vmlinux := -e stext - - OBJCOPYFLAGS objcopy flags - - When $(call if_changed,objcopy) is used to translate a .o file, - the flags specified in OBJCOPYFLAGS will be used. - $(call if_changed,objcopy) is often used to generate raw binaries on - vmlinux. - - Example: - #arch/s390/Makefile - OBJCOPYFLAGS := -O binary - - #arch/s390/boot/Makefile - $(obj)/image: vmlinux FORCE - $(call if_changed,objcopy) - - In this example, the binary $(obj)/image is a binary version of - vmlinux. The usage of $(call if_changed,xxx) will be described later. - - KBUILD_AFLAGS $(AS) assembler flags - - Default value - see top level Makefile - Append or modify as required per architecture. - - Example: - #arch/sparc64/Makefile - KBUILD_AFLAGS += -m64 -mcpu=ultrasparc - - KBUILD_CFLAGS $(CC) compiler flags - - Default value - see top level Makefile - Append or modify as required per architecture. - - Often, the KBUILD_CFLAGS variable depends on the configuration. - - Example: - #arch/x86/boot/compressed/Makefile - cflags-$(CONFIG_X86_32) := -march=i386 - cflags-$(CONFIG_X86_64) := -mcmodel=small - KBUILD_CFLAGS += $(cflags-y) - - Many arch Makefiles dynamically run the target C compiler to - probe supported options: - - #arch/x86/Makefile - - ... - cflags-$(CONFIG_MPENTIUMII) += $(call cc-option,\ - -march=pentium2,-march=i686) - ... - # Disable unit-at-a-time mode ... - KBUILD_CFLAGS += $(call cc-option,-fno-unit-at-a-time) - ... - - - The first example utilises the trick that a config option expands - to 'y' when selected. - - KBUILD_AFLAGS_KERNEL $(AS) options specific for built-in - - $(KBUILD_AFLAGS_KERNEL) contains extra C compiler flags used to compile - resident kernel code. - - KBUILD_AFLAGS_MODULE Options for $(AS) when building modules - - $(KBUILD_AFLAGS_MODULE) is used to add arch-specific options that - are used for $(AS). - From commandline AFLAGS_MODULE shall be used (see kbuild.txt). - - KBUILD_CFLAGS_KERNEL $(CC) options specific for built-in - - $(KBUILD_CFLAGS_KERNEL) contains extra C compiler flags used to compile - resident kernel code. - - KBUILD_CFLAGS_MODULE Options for $(CC) when building modules - - $(KBUILD_CFLAGS_MODULE) is used to add arch-specific options that - are used for $(CC). - From commandline CFLAGS_MODULE shall be used (see kbuild.txt). - - KBUILD_LDFLAGS_MODULE Options for $(LD) when linking modules - - $(KBUILD_LDFLAGS_MODULE) is used to add arch-specific options - used when linking modules. This is often a linker script. - From commandline LDFLAGS_MODULE shall be used (see kbuild.txt). - - KBUILD_ARFLAGS Options for $(AR) when creating archives - - $(KBUILD_ARFLAGS) set by the top level Makefile to "D" (deterministic - mode) if this option is supported by $(AR). - - ARCH_CPPFLAGS, ARCH_AFLAGS, ARCH_CFLAGS Overrides the kbuild defaults - - These variables are appended to the KBUILD_CPPFLAGS, - KBUILD_AFLAGS, and KBUILD_CFLAGS, respectively, after the - top-level Makefile has set any other flags. This provides a - means for an architecture to override the defaults. - - ---- 6.2 Add prerequisites to archheaders: - - The archheaders: rule is used to generate header files that - may be installed into user space by "make header_install" or - "make headers_install_all". In order to support - "make headers_install_all", this target has to be able to run - on an unconfigured tree, or a tree configured for another - architecture. - - It is run before "make archprepare" when run on the - architecture itself. - - ---- 6.3 Add prerequisites to archprepare: - - The archprepare: rule is used to list prerequisites that need to be - built before starting to descend down in the subdirectories. - This is usually used for header files containing assembler constants. - - Example: - #arch/arm/Makefile - archprepare: maketools - - In this example, the file target maketools will be processed - before descending down in the subdirectories. - See also chapter XXX-TODO that describe how kbuild supports - generating offset header files. - - ---- 6.4 List directories to visit when descending - - An arch Makefile cooperates with the top Makefile to define variables - which specify how to build the vmlinux file. Note that there is no - corresponding arch-specific section for modules; the module-building - machinery is all architecture-independent. - - - head-y, init-y, core-y, libs-y, drivers-y, net-y - - $(head-y) lists objects to be linked first in vmlinux. - $(libs-y) lists directories where a lib.a archive can be located. - The rest list directories where a built-in.a object file can be - located. - - $(init-y) objects will be located after $(head-y). - Then the rest follows in this order: - $(core-y), $(libs-y), $(drivers-y) and $(net-y). - - The top level Makefile defines values for all generic directories, - and arch/$(ARCH)/Makefile only adds architecture-specific directories. - - Example: - #arch/sparc64/Makefile - core-y += arch/sparc64/kernel/ - libs-y += arch/sparc64/prom/ arch/sparc64/lib/ - drivers-$(CONFIG_OPROFILE) += arch/sparc64/oprofile/ - - ---- 6.5 Architecture-specific boot images - - An arch Makefile specifies goals that take the vmlinux file, compress - it, wrap it in bootstrapping code, and copy the resulting files - somewhere. This includes various kinds of installation commands. - The actual goals are not standardized across architectures. - - It is common to locate any additional processing in a boot/ - directory below arch/$(ARCH)/. - - Kbuild does not provide any smart way to support building a - target specified in boot/. Therefore arch/$(ARCH)/Makefile shall - call make manually to build a target in boot/. - - The recommended approach is to include shortcuts in - arch/$(ARCH)/Makefile, and use the full path when calling down - into the arch/$(ARCH)/boot/Makefile. - - Example: - #arch/x86/Makefile - boot := arch/x86/boot - bzImage: vmlinux - $(Q)$(MAKE) $(build)=$(boot) $(boot)/$@ - - "$(Q)$(MAKE) $(build)=" is the recommended way to invoke - make in a subdirectory. - - There are no rules for naming architecture-specific targets, - but executing "make help" will list all relevant targets. - To support this, $(archhelp) must be defined. - - Example: - #arch/x86/Makefile - define archhelp - echo '* bzImage - Image (arch/$(ARCH)/boot/bzImage)' - endif - - When make is executed without arguments, the first goal encountered - will be built. In the top level Makefile the first goal present - is all:. - An architecture shall always, per default, build a bootable image. - In "make help", the default goal is highlighted with a '*'. - Add a new prerequisite to all: to select a default goal different - from vmlinux. - - Example: - #arch/x86/Makefile - all: bzImage - - When "make" is executed without arguments, bzImage will be built. - ---- 6.6 Building non-kbuild targets - - extra-y - - extra-y specifies additional targets created in the current - directory, in addition to any targets specified by obj-*. - - Listing all targets in extra-y is required for two purposes: - 1) Enable kbuild to check changes in command lines - - When $(call if_changed,xxx) is used - 2) kbuild knows what files to delete during "make clean" - - Example: - #arch/x86/kernel/Makefile - extra-y := head.o init_task.o - - In this example, extra-y is used to list object files that - shall be built, but shall not be linked as part of built-in.a. - - ---- 6.7 Commands useful for building a boot image - - Kbuild provides a few macros that are useful when building a - boot image. - - if_changed - - if_changed is the infrastructure used for the following commands. - - Usage: - target: source(s) FORCE - $(call if_changed,ld/objcopy/gzip/...) - - When the rule is evaluated, it is checked to see if any files - need an update, or the command line has changed since the last - invocation. The latter will force a rebuild if any options - to the executable have changed. - Any target that utilises if_changed must be listed in $(targets), - otherwise the command line check will fail, and the target will - always be built. - Assignments to $(targets) are without $(obj)/ prefix. - if_changed may be used in conjunction with custom commands as - defined in 6.8 "Custom kbuild commands". - - Note: It is a typical mistake to forget the FORCE prerequisite. - Another common pitfall is that whitespace is sometimes - significant; for instance, the below will fail (note the extra space - after the comma): - target: source(s) FORCE - #WRONG!# $(call if_changed, ld/objcopy/gzip/...) - - Note: if_changed should not be used more than once per target. - It stores the executed command in a corresponding .cmd - file and multiple calls would result in overwrites and - unwanted results when the target is up to date and only the - tests on changed commands trigger execution of commands. - - ld - Link target. Often, LDFLAGS_$@ is used to set specific options to ld. - - Example: - #arch/x86/boot/Makefile - LDFLAGS_bootsect := -Ttext 0x0 -s --oformat binary - LDFLAGS_setup := -Ttext 0x0 -s --oformat binary -e begtext - - targets += setup setup.o bootsect bootsect.o - $(obj)/setup $(obj)/bootsect: %: %.o FORCE - $(call if_changed,ld) - - In this example, there are two possible targets, requiring different - options to the linker. The linker options are specified using the - LDFLAGS_$@ syntax - one for each potential target. - $(targets) are assigned all potential targets, by which kbuild knows - the targets and will: - 1) check for commandline changes - 2) delete target during make clean - - The ": %: %.o" part of the prerequisite is a shorthand that - frees us from listing the setup.o and bootsect.o files. - Note: It is a common mistake to forget the "targets :=" assignment, - resulting in the target file being recompiled for no - obvious reason. - - objcopy - Copy binary. Uses OBJCOPYFLAGS usually specified in - arch/$(ARCH)/Makefile. - OBJCOPYFLAGS_$@ may be used to set additional options. - - gzip - Compress target. Use maximum compression to compress target. - - Example: - #arch/x86/boot/compressed/Makefile - $(obj)/vmlinux.bin.gz: $(vmlinux.bin.all-y) FORCE - $(call if_changed,gzip) - - dtc - Create flattened device tree blob object suitable for linking - into vmlinux. Device tree blobs linked into vmlinux are placed - in an init section in the image. Platform code *must* copy the - blob to non-init memory prior to calling unflatten_device_tree(). - - To use this command, simply add *.dtb into obj-y or targets, or make - some other target depend on %.dtb - - A central rule exists to create $(obj)/%.dtb from $(src)/%.dts; - architecture Makefiles do no need to explicitly write out that rule. - - Example: - targets += $(dtb-y) - DTC_FLAGS ?= -p 1024 - ---- 6.8 Custom kbuild commands - - When kbuild is executing with KBUILD_VERBOSE=0, then only a shorthand - of a command is normally displayed. - To enable this behaviour for custom commands kbuild requires - two variables to be set: - quiet_cmd_ - what shall be echoed - cmd_ - the command to execute - - Example: - # - quiet_cmd_image = BUILD $@ - cmd_image = $(obj)/tools/build $(BUILDFLAGS) \ - $(obj)/vmlinux.bin > $@ - - targets += bzImage - $(obj)/bzImage: $(obj)/vmlinux.bin $(obj)/tools/build FORCE - $(call if_changed,image) - @echo 'Kernel: $@ is ready' - - When updating the $(obj)/bzImage target, the line - - BUILD arch/x86/boot/bzImage - - will be displayed with "make KBUILD_VERBOSE=0". - - ---- 6.9 Preprocessing linker scripts - - When the vmlinux image is built, the linker script - arch/$(ARCH)/kernel/vmlinux.lds is used. - The script is a preprocessed variant of the file vmlinux.lds.S - located in the same directory. - kbuild knows .lds files and includes a rule *lds.S -> *lds. - - Example: - #arch/x86/kernel/Makefile - always := vmlinux.lds - - #Makefile - export CPPFLAGS_vmlinux.lds += -P -C -U$(ARCH) - - The assignment to $(always) is used to tell kbuild to build the - target vmlinux.lds. - The assignment to $(CPPFLAGS_vmlinux.lds) tells kbuild to use the - specified options when building the target vmlinux.lds. - - When building the *.lds target, kbuild uses the variables: - KBUILD_CPPFLAGS : Set in top-level Makefile - cppflags-y : May be set in the kbuild makefile - CPPFLAGS_$(@F) : Target-specific flags. - Note that the full filename is used in this - assignment. - - The kbuild infrastructure for *lds files is used in several - architecture-specific files. - ---- 6.10 Generic header files - - The directory include/asm-generic contains the header files - that may be shared between individual architectures. - The recommended approach how to use a generic header file is - to list the file in the Kbuild file. - See "7.2 generic-y" for further info on syntax etc. - ---- 6.11 Post-link pass - - If the file arch/xxx/Makefile.postlink exists, this makefile - will be invoked for post-link objects (vmlinux and modules.ko) - for architectures to run post-link passes on. Must also handle - the clean target. - - This pass runs after kallsyms generation. If the architecture - needs to modify symbol locations, rather than manipulate the - kallsyms, it may be easier to add another postlink target for - .tmp_vmlinux? targets to be called from link-vmlinux.sh. - - For example, powerpc uses this to check relocation sanity of - the linked vmlinux file. - -=== 7 Kbuild syntax for exported headers - -The kernel includes a set of headers that is exported to userspace. -Many headers can be exported as-is but other headers require a -minimal pre-processing before they are ready for user-space. -The pre-processing does: -- drop kernel-specific annotations -- drop include of compiler.h -- drop all sections that are kernel internal (guarded by ifdef __KERNEL__) - -All headers under include/uapi/, include/generated/uapi/, -arch//include/uapi/ and arch//include/generated/uapi/ -are exported. - -A Kbuild file may be defined under arch//include/uapi/asm/ and -arch//include/asm/ to list asm files coming from asm-generic. -See subsequent chapter for the syntax of the Kbuild file. - ---- 7.1 no-export-headers - - no-export-headers is essentially used by include/uapi/linux/Kbuild to - avoid exporting specific headers (e.g. kvm.h) on architectures that do - not support it. It should be avoided as much as possible. - ---- 7.2 generic-y - - If an architecture uses a verbatim copy of a header from - include/asm-generic then this is listed in the file - arch/$(ARCH)/include/asm/Kbuild like this: - - Example: - #arch/x86/include/asm/Kbuild - generic-y += termios.h - generic-y += rtc.h - - During the prepare phase of the build a wrapper include - file is generated in the directory: - - arch/$(ARCH)/include/generated/asm - - When a header is exported where the architecture uses - the generic header a similar wrapper is generated as part - of the set of exported headers in the directory: - - usr/include/asm - - The generated wrapper will in both cases look like the following: - - Example: termios.h - #include - ---- 7.3 generated-y - - If an architecture generates other header files alongside generic-y - wrappers, generated-y specifies them. - - This prevents them being treated as stale asm-generic wrappers and - removed. - - Example: - #arch/x86/include/asm/Kbuild - generated-y += syscalls_32.h - ---- 7.4 mandatory-y - - mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild - to define the minimum set of ASM headers that all architectures must have. - - This works like optional generic-y. If a mandatory header is missing - in arch/$(ARCH)/include/(uapi/)/asm, Kbuild will automatically generate - a wrapper of the asm-generic one. - - The convention is to list one subdir per line and - preferably in alphabetic order. - -=== 8 Kbuild Variables - -The top Makefile exports the following variables: - - VERSION, PATCHLEVEL, SUBLEVEL, EXTRAVERSION - - These variables define the current kernel version. A few arch - Makefiles actually use these values directly; they should use - $(KERNELRELEASE) instead. - - $(VERSION), $(PATCHLEVEL), and $(SUBLEVEL) define the basic - three-part version number, such as "2", "4", and "0". These three - values are always numeric. - - $(EXTRAVERSION) defines an even tinier sublevel for pre-patches - or additional patches. It is usually some non-numeric string - such as "-pre4", and is often blank. - - KERNELRELEASE - - $(KERNELRELEASE) is a single string such as "2.4.0-pre4", suitable - for constructing installation directory names or showing in - version strings. Some arch Makefiles use it for this purpose. - - ARCH - - This variable defines the target architecture, such as "i386", - "arm", or "sparc". Some kbuild Makefiles test $(ARCH) to - determine which files to compile. - - By default, the top Makefile sets $(ARCH) to be the same as the - host system architecture. For a cross build, a user may - override the value of $(ARCH) on the command line: - - make ARCH=m68k ... - - - INSTALL_PATH - - This variable defines a place for the arch Makefiles to install - the resident kernel image and System.map file. - Use this for architecture-specific install targets. - - INSTALL_MOD_PATH, MODLIB - - $(INSTALL_MOD_PATH) specifies a prefix to $(MODLIB) for module - installation. This variable is not defined in the Makefile but - may be passed in by the user if desired. - - $(MODLIB) specifies the directory for module installation. - The top Makefile defines $(MODLIB) to - $(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE). The user may - override this value on the command line if desired. - - INSTALL_MOD_STRIP - - If this variable is specified, it will cause modules to be stripped - after they are installed. If INSTALL_MOD_STRIP is '1', then the - default option --strip-debug will be used. Otherwise, the - INSTALL_MOD_STRIP value will be used as the option(s) to the strip - command. - - -=== 9 Makefile language - -The kernel Makefiles are designed to be run with GNU Make. The Makefiles -use only the documented features of GNU Make, but they do use many -GNU extensions. - -GNU Make supports elementary list-processing functions. The kernel -Makefiles use a novel style of list building and manipulation with few -"if" statements. - -GNU Make has two assignment operators, ":=" and "=". ":=" performs -immediate evaluation of the right-hand side and stores an actual string -into the left-hand side. "=" is like a formula definition; it stores the -right-hand side in an unevaluated form and then evaluates this form each -time the left-hand side is used. - -There are some cases where "=" is appropriate. Usually, though, ":=" -is the right choice. - -=== 10 Credits - -Original version made by Michael Elizabeth Chastain, -Updates by Kai Germaschewski -Updates by Sam Ravnborg -Language QA by Jan Engelhardt - -=== 11 TODO - -- Describe how kbuild supports shipped files with _shipped. -- Generating offset header files. -- Add more variables to section 7? - - - diff --git a/Documentation/kbuild/modules.rst b/Documentation/kbuild/modules.rst new file mode 100644 index 000000000000..24e763482650 --- /dev/null +++ b/Documentation/kbuild/modules.rst @@ -0,0 +1,571 @@ +========================= +Building External Modules +========================= + +This document describes how to build an out-of-tree kernel module. + +..

Tips & Tricks + --- 7.1 Testing for CONFIG_FOO_BAR + + + +1. Introduction +=============== + +"kbuild" is the build system used by the Linux kernel. Modules must use +kbuild to stay compatible with changes in the build infrastructure and +to pick up the right flags to "gcc." Functionality for building modules +both in-tree and out-of-tree is provided. The method for building +either is similar, and all modules are initially developed and built +out-of-tree. + +Covered in this document is information aimed at developers interested +in building out-of-tree (or "external") modules. The author of an +external module should supply a makefile that hides most of the +complexity, so one only has to type "make" to build the module. This is +easily accomplished, and a complete example will be presented in +section 3. + + +2. How to Build External Modules +================================ + +To build external modules, you must have a prebuilt kernel available +that contains the configuration and header files used in the build. +Also, the kernel must have been built with modules enabled. If you are +using a distribution kernel, there will be a package for the kernel you +are running provided by your distribution. + +An alternative is to use the "make" target "modules_prepare." This will +make sure the kernel contains the information required. The target +exists solely as a simple way to prepare a kernel source tree for +building external modules. + +NOTE: "modules_prepare" will not build Module.symvers even if +CONFIG_MODVERSIONS is set; therefore, a full kernel build needs to be +executed to make module versioning work. + +2.1 Command Syntax +================== + + The command to build an external module is:: + + $ make -C M=$PWD + + The kbuild system knows that an external module is being built + due to the "M=" option given in the command. + + To build against the running kernel use:: + + $ make -C /lib/modules/`uname -r`/build M=$PWD + + Then to install the module(s) just built, add the target + "modules_install" to the command:: + + $ make -C /lib/modules/`uname -r`/build M=$PWD modules_install + +2.2 Options +=========== + + ($KDIR refers to the path of the kernel source directory.) + + make -C $KDIR M=$PWD + + -C $KDIR + The directory where the kernel source is located. + "make" will actually change to the specified directory + when executing and will change back when finished. + + M=$PWD + Informs kbuild that an external module is being built. + The value given to "M" is the absolute path of the + directory where the external module (kbuild file) is + located. + +2.3 Targets +=========== + + When building an external module, only a subset of the "make" + targets are available. + + make -C $KDIR M=$PWD [target] + + The default will build the module(s) located in the current + directory, so a target does not need to be specified. All + output files will also be generated in this directory. No + attempts are made to update the kernel source, and it is a + precondition that a successful "make" has been executed for the + kernel. + + modules + The default target for external modules. It has the + same functionality as if no target was specified. See + description above. + + modules_install + Install the external module(s). The default location is + /lib/modules//extra/, but a prefix may + be added with INSTALL_MOD_PATH (discussed in section 5). + + clean + Remove all generated files in the module directory only. + + help + List the available targets for external modules. + +2.4 Building Separate Files +=========================== + + It is possible to build single files that are part of a module. + This works equally well for the kernel, a module, and even for + external modules. + + Example (The module foo.ko, consist of bar.o and baz.o):: + + make -C $KDIR M=$PWD bar.lst + make -C $KDIR M=$PWD baz.o + make -C $KDIR M=$PWD foo.ko + make -C $KDIR M=$PWD ./ + + +3. Creating a Kbuild File for an External Module +================================================ + +In the last section we saw the command to build a module for the +running kernel. The module is not actually built, however, because a +build file is required. Contained in this file will be the name of +the module(s) being built, along with the list of requisite source +files. The file may be as simple as a single line:: + + obj-m := .o + +The kbuild system will build .o from .c, +and, after linking, will result in the kernel module .ko. +The above line can be put in either a "Kbuild" file or a "Makefile." +When the module is built from multiple sources, an additional line is +needed listing the files:: + + -y := .o .o ... + +NOTE: Further documentation describing the syntax used by kbuild is +located in Documentation/kbuild/makefiles.rst. + +The examples below demonstrate how to create a build file for the +module 8123.ko, which is built from the following files:: + + 8123_if.c + 8123_if.h + 8123_pci.c + 8123_bin.o_shipped <= Binary blob + +--- 3.1 Shared Makefile + + An external module always includes a wrapper makefile that + supports building the module using "make" with no arguments. + This target is not used by kbuild; it is only for convenience. + Additional functionality, such as test targets, can be included + but should be filtered out from kbuild due to possible name + clashes. + + Example 1:: + + --> filename: Makefile + ifneq ($(KERNELRELEASE),) + # kbuild part of makefile + obj-m := 8123.o + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + else + # normal makefile + KDIR ?= /lib/modules/`uname -r`/build + + default: + $(MAKE) -C $(KDIR) M=$$PWD + + # Module specific targets + genbin: + echo "X" > 8123_bin.o_shipped + + endif + + The check for KERNELRELEASE is used to separate the two parts + of the makefile. In the example, kbuild will only see the two + assignments, whereas "make" will see everything except these + two assignments. This is due to two passes made on the file: + the first pass is by the "make" instance run on the command + line; the second pass is by the kbuild system, which is + initiated by the parameterized "make" in the default target. + +3.2 Separate Kbuild File and Makefile +------------------------------------- + + In newer versions of the kernel, kbuild will first look for a + file named "Kbuild," and only if that is not found, will it + then look for a makefile. Utilizing a "Kbuild" file allows us + to split up the makefile from example 1 into two files: + + Example 2:: + + --> filename: Kbuild + obj-m := 8123.o + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + --> filename: Makefile + KDIR ?= /lib/modules/`uname -r`/build + + default: + $(MAKE) -C $(KDIR) M=$$PWD + + # Module specific targets + genbin: + echo "X" > 8123_bin.o_shipped + + The split in example 2 is questionable due to the simplicity of + each file; however, some external modules use makefiles + consisting of several hundred lines, and here it really pays + off to separate the kbuild part from the rest. + + The next example shows a backward compatible version. + + Example 3:: + + --> filename: Kbuild + obj-m := 8123.o + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + --> filename: Makefile + ifneq ($(KERNELRELEASE),) + # kbuild part of makefile + include Kbuild + + else + # normal makefile + KDIR ?= /lib/modules/`uname -r`/build + + default: + $(MAKE) -C $(KDIR) M=$$PWD + + # Module specific targets + genbin: + echo "X" > 8123_bin.o_shipped + + endif + + Here the "Kbuild" file is included from the makefile. This + allows an older version of kbuild, which only knows of + makefiles, to be used when the "make" and kbuild parts are + split into separate files. + +3.3 Binary Blobs +---------------- + + Some external modules need to include an object file as a blob. + kbuild has support for this, but requires the blob file to be + named _shipped. When the kbuild rules kick in, a copy + of _shipped is created with _shipped stripped off, + giving us . This shortened filename can be used in + the assignment to the module. + + Throughout this section, 8123_bin.o_shipped has been used to + build the kernel module 8123.ko; it has been included as + 8123_bin.o:: + + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + Although there is no distinction between the ordinary source + files and the binary file, kbuild will pick up different rules + when creating the object file for the module. + +3.4 Building Multiple Modules +============================= + + kbuild supports building multiple modules with a single build + file. For example, if you wanted to build two modules, foo.ko + and bar.ko, the kbuild lines would be:: + + obj-m := foo.o bar.o + foo-y := + bar-y := + + It is that simple! + + +4. Include Files +================ + +Within the kernel, header files are kept in standard locations +according to the following rule: + + * If the header file only describes the internal interface of a + module, then the file is placed in the same directory as the + source files. + * If the header file describes an interface used by other parts + of the kernel that are located in different directories, then + the file is placed in include/linux/. + + NOTE: + There are two notable exceptions to this rule: larger + subsystems have their own directory under include/, such as + include/scsi; and architecture specific headers are located + under arch/$(ARCH)/include/. + +4.1 Kernel Includes +------------------- + + To include a header file located under include/linux/, simply + use:: + + #include + + kbuild will add options to "gcc" so the relevant directories + are searched. + +4.2 Single Subdirectory +----------------------- + + External modules tend to place header files in a separate + include/ directory where their source is located, although this + is not the usual kernel style. To inform kbuild of the + directory, use either ccflags-y or CFLAGS_.o. + + Using the example from section 3, if we moved 8123_if.h to a + subdirectory named include, the resulting kbuild file would + look like:: + + --> filename: Kbuild + obj-m := 8123.o + + ccflags-y := -Iinclude + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + Note that in the assignment there is no space between -I and + the path. This is a limitation of kbuild: there must be no + space present. + +4.3 Several Subdirectories +-------------------------- + + kbuild can handle files that are spread over several directories. + Consider the following example:: + + . + |__ src + | |__ complex_main.c + | |__ hal + | |__ hardwareif.c + | |__ include + | |__ hardwareif.h + |__ include + |__ complex.h + + To build the module complex.ko, we then need the following + kbuild file:: + + --> filename: Kbuild + obj-m := complex.o + complex-y := src/complex_main.o + complex-y += src/hal/hardwareif.o + + ccflags-y := -I$(src)/include + ccflags-y += -I$(src)/src/hal/include + + As you can see, kbuild knows how to handle object files located + in other directories. The trick is to specify the directory + relative to the kbuild file's location. That being said, this + is NOT recommended practice. + + For the header files, kbuild must be explicitly told where to + look. When kbuild executes, the current directory is always the + root of the kernel tree (the argument to "-C") and therefore an + absolute path is needed. $(src) provides the absolute path by + pointing to the directory where the currently executing kbuild + file is located. + + +5. Module Installation +====================== + +Modules which are included in the kernel are installed in the +directory: + + /lib/modules/$(KERNELRELEASE)/kernel/ + +And external modules are installed in: + + /lib/modules/$(KERNELRELEASE)/extra/ + +5.1 INSTALL_MOD_PATH +-------------------- + + Above are the default directories but as always some level of + customization is possible. A prefix can be added to the + installation path using the variable INSTALL_MOD_PATH:: + + $ make INSTALL_MOD_PATH=/frodo modules_install + => Install dir: /frodo/lib/modules/$(KERNELRELEASE)/kernel/ + + INSTALL_MOD_PATH may be set as an ordinary shell variable or, + as shown above, can be specified on the command line when + calling "make." This has effect when installing both in-tree + and out-of-tree modules. + +5.2 INSTALL_MOD_DIR +------------------- + + External modules are by default installed to a directory under + /lib/modules/$(KERNELRELEASE)/extra/, but you may wish to + locate modules for a specific functionality in a separate + directory. For this purpose, use INSTALL_MOD_DIR to specify an + alternative name to "extra.":: + + $ make INSTALL_MOD_DIR=gandalf -C $KDIR \ + M=$PWD modules_install + => Install dir: /lib/modules/$(KERNELRELEASE)/gandalf/ + + +6. Module Versioning +==================== + +Module versioning is enabled by the CONFIG_MODVERSIONS tag, and is used +as a simple ABI consistency check. A CRC value of the full prototype +for an exported symbol is created.

Tips & Tricks - --- 7.1 Testing for CONFIG_FOO_BAR - - - -=== 1. Introduction - -"kbuild" is the build system used by the Linux kernel. Modules must use -kbuild to stay compatible with changes in the build infrastructure and -to pick up the right flags to "gcc." Functionality for building modules -both in-tree and out-of-tree is provided. The method for building -either is similar, and all modules are initially developed and built -out-of-tree. - -Covered in this document is information aimed at developers interested -in building out-of-tree (or "external") modules. The author of an -external module should supply a makefile that hides most of the -complexity, so one only has to type "make" to build the module. This is -easily accomplished, and a complete example will be presented in -section 3. - - -=== 2. How to Build External Modules - -To build external modules, you must have a prebuilt kernel available -that contains the configuration and header files used in the build. -Also, the kernel must have been built with modules enabled. If you are -using a distribution kernel, there will be a package for the kernel you -are running provided by your distribution. - -An alternative is to use the "make" target "modules_prepare." This will -make sure the kernel contains the information required. The target -exists solely as a simple way to prepare a kernel source tree for -building external modules. - -NOTE: "modules_prepare" will not build Module.symvers even if -CONFIG_MODVERSIONS is set; therefore, a full kernel build needs to be -executed to make module versioning work. - ---- 2.1 Command Syntax - - The command to build an external module is: - - $ make -C M=$PWD - - The kbuild system knows that an external module is being built - due to the "M=" option given in the command. - - To build against the running kernel use: - - $ make -C /lib/modules/`uname -r`/build M=$PWD - - Then to install the module(s) just built, add the target - "modules_install" to the command: - - $ make -C /lib/modules/`uname -r`/build M=$PWD modules_install - ---- 2.2 Options - - ($KDIR refers to the path of the kernel source directory.) - - make -C $KDIR M=$PWD - - -C $KDIR - The directory where the kernel source is located. - "make" will actually change to the specified directory - when executing and will change back when finished. - - M=$PWD - Informs kbuild that an external module is being built. - The value given to "M" is the absolute path of the - directory where the external module (kbuild file) is - located. - ---- 2.3 Targets - - When building an external module, only a subset of the "make" - targets are available. - - make -C $KDIR M=$PWD [target] - - The default will build the module(s) located in the current - directory, so a target does not need to be specified. All - output files will also be generated in this directory. No - attempts are made to update the kernel source, and it is a - precondition that a successful "make" has been executed for the - kernel. - - modules - The default target for external modules. It has the - same functionality as if no target was specified. See - description above. - - modules_install - Install the external module(s). The default location is - /lib/modules//extra/, but a prefix may - be added with INSTALL_MOD_PATH (discussed in section 5). - - clean - Remove all generated files in the module directory only. - - help - List the available targets for external modules. - ---- 2.4 Building Separate Files - - It is possible to build single files that are part of a module. - This works equally well for the kernel, a module, and even for - external modules. - - Example (The module foo.ko, consist of bar.o and baz.o): - make -C $KDIR M=$PWD bar.lst - make -C $KDIR M=$PWD baz.o - make -C $KDIR M=$PWD foo.ko - make -C $KDIR M=$PWD ./ - - -=== 3. Creating a Kbuild File for an External Module - -In the last section we saw the command to build a module for the -running kernel. The module is not actually built, however, because a -build file is required. Contained in this file will be the name of -the module(s) being built, along with the list of requisite source -files. The file may be as simple as a single line: - - obj-m := .o - -The kbuild system will build .o from .c, -and, after linking, will result in the kernel module .ko. -The above line can be put in either a "Kbuild" file or a "Makefile." -When the module is built from multiple sources, an additional line is -needed listing the files: - - -y := .o .o ... - -NOTE: Further documentation describing the syntax used by kbuild is -located in Documentation/kbuild/makefiles.txt. - -The examples below demonstrate how to create a build file for the -module 8123.ko, which is built from the following files: - - 8123_if.c - 8123_if.h - 8123_pci.c - 8123_bin.o_shipped <= Binary blob - ---- 3.1 Shared Makefile - - An external module always includes a wrapper makefile that - supports building the module using "make" with no arguments. - This target is not used by kbuild; it is only for convenience. - Additional functionality, such as test targets, can be included - but should be filtered out from kbuild due to possible name - clashes. - - Example 1: - --> filename: Makefile - ifneq ($(KERNELRELEASE),) - # kbuild part of makefile - obj-m := 8123.o - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - else - # normal makefile - KDIR ?= /lib/modules/`uname -r`/build - - default: - $(MAKE) -C $(KDIR) M=$$PWD - - # Module specific targets - genbin: - echo "X" > 8123_bin.o_shipped - - endif - - The check for KERNELRELEASE is used to separate the two parts - of the makefile. In the example, kbuild will only see the two - assignments, whereas "make" will see everything except these - two assignments. This is due to two passes made on the file: - the first pass is by the "make" instance run on the command - line; the second pass is by the kbuild system, which is - initiated by the parameterized "make" in the default target. - ---- 3.2 Separate Kbuild File and Makefile - - In newer versions of the kernel, kbuild will first look for a - file named "Kbuild," and only if that is not found, will it - then look for a makefile. Utilizing a "Kbuild" file allows us - to split up the makefile from example 1 into two files: - - Example 2: - --> filename: Kbuild - obj-m := 8123.o - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - --> filename: Makefile - KDIR ?= /lib/modules/`uname -r`/build - - default: - $(MAKE) -C $(KDIR) M=$$PWD - - # Module specific targets - genbin: - echo "X" > 8123_bin.o_shipped - - The split in example 2 is questionable due to the simplicity of - each file; however, some external modules use makefiles - consisting of several hundred lines, and here it really pays - off to separate the kbuild part from the rest. - - The next example shows a backward compatible version. - - Example 3: - --> filename: Kbuild - obj-m := 8123.o - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - --> filename: Makefile - ifneq ($(KERNELRELEASE),) - # kbuild part of makefile - include Kbuild - - else - # normal makefile - KDIR ?= /lib/modules/`uname -r`/build - - default: - $(MAKE) -C $(KDIR) M=$$PWD - - # Module specific targets - genbin: - echo "X" > 8123_bin.o_shipped - - endif - - Here the "Kbuild" file is included from the makefile. This - allows an older version of kbuild, which only knows of - makefiles, to be used when the "make" and kbuild parts are - split into separate files. - ---- 3.3 Binary Blobs - - Some external modules need to include an object file as a blob. - kbuild has support for this, but requires the blob file to be - named _shipped. When the kbuild rules kick in, a copy - of _shipped is created with _shipped stripped off, - giving us . This shortened filename can be used in - the assignment to the module. - - Throughout this section, 8123_bin.o_shipped has been used to - build the kernel module 8123.ko; it has been included as - 8123_bin.o. - - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - Although there is no distinction between the ordinary source - files and the binary file, kbuild will pick up different rules - when creating the object file for the module. - ---- 3.4 Building Multiple Modules - - kbuild supports building multiple modules with a single build - file. For example, if you wanted to build two modules, foo.ko - and bar.ko, the kbuild lines would be: - - obj-m := foo.o bar.o - foo-y := - bar-y := - - It is that simple! - - -=== 4. Include Files - -Within the kernel, header files are kept in standard locations -according to the following rule: - - * If the header file only describes the internal interface of a - module, then the file is placed in the same directory as the - source files. - * If the header file describes an interface used by other parts - of the kernel that are located in different directories, then - the file is placed in include/linux/. - - NOTE: There are two notable exceptions to this rule: larger - subsystems have their own directory under include/, such as - include/scsi; and architecture specific headers are located - under arch/$(ARCH)/include/. - ---- 4.1 Kernel Includes - - To include a header file located under include/linux/, simply - use: - - #include - - kbuild will add options to "gcc" so the relevant directories - are searched. - ---- 4.2 Single Subdirectory - - External modules tend to place header files in a separate - include/ directory where their source is located, although this - is not the usual kernel style. To inform kbuild of the - directory, use either ccflags-y or CFLAGS_.o. - - Using the example from section 3, if we moved 8123_if.h to a - subdirectory named include, the resulting kbuild file would - look like: - - --> filename: Kbuild - obj-m := 8123.o - - ccflags-y := -Iinclude - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - Note that in the assignment there is no space between -I and - the path. This is a limitation of kbuild: there must be no - space present. - ---- 4.3 Several Subdirectories - - kbuild can handle files that are spread over several directories. - Consider the following example: - - . - |__ src - | |__ complex_main.c - | |__ hal - | |__ hardwareif.c - | |__ include - | |__ hardwareif.h - |__ include - |__ complex.h - - To build the module complex.ko, we then need the following - kbuild file: - - --> filename: Kbuild - obj-m := complex.o - complex-y := src/complex_main.o - complex-y += src/hal/hardwareif.o - - ccflags-y := -I$(src)/include - ccflags-y += -I$(src)/src/hal/include - - As you can see, kbuild knows how to handle object files located - in other directories. The trick is to specify the directory - relative to the kbuild file's location. That being said, this - is NOT recommended practice. - - For the header files, kbuild must be explicitly told where to - look. When kbuild executes, the current directory is always the - root of the kernel tree (the argument to "-C") and therefore an - absolute path is needed. $(src) provides the absolute path by - pointing to the directory where the currently executing kbuild - file is located. - - -=== 5. Module Installation - -Modules which are included in the kernel are installed in the -directory: - - /lib/modules/$(KERNELRELEASE)/kernel/ - -And external modules are installed in: - - /lib/modules/$(KERNELRELEASE)/extra/ - ---- 5.1 INSTALL_MOD_PATH - - Above are the default directories but as always some level of - customization is possible. A prefix can be added to the - installation path using the variable INSTALL_MOD_PATH: - - $ make INSTALL_MOD_PATH=/frodo modules_install - => Install dir: /frodo/lib/modules/$(KERNELRELEASE)/kernel/ - - INSTALL_MOD_PATH may be set as an ordinary shell variable or, - as shown above, can be specified on the command line when - calling "make." This has effect when installing both in-tree - and out-of-tree modules. - ---- 5.2 INSTALL_MOD_DIR - - External modules are by default installed to a directory under - /lib/modules/$(KERNELRELEASE)/extra/, but you may wish to - locate modules for a specific functionality in a separate - directory. For this purpose, use INSTALL_MOD_DIR to specify an - alternative name to "extra." - - $ make INSTALL_MOD_DIR=gandalf -C $KDIR \ - M=$PWD modules_install - => Install dir: /lib/modules/$(KERNELRELEASE)/gandalf/ - - -=== 6. Module Versioning - -Module versioning is enabled by the CONFIG_MODVERSIONS tag, and is used -as a simple ABI consistency check. A CRC value of the full prototype -for an exported symbol is created. When a module is loaded/used, the -CRC values contained in the kernel are compared with similar values in -the module; if they are not equal, the kernel refuses to load the -module. - -Module.symvers contains a list of all exported symbols from a kernel -build. - ---- 6.1 Symbols From the Kernel (vmlinux + modules) - - During a kernel build, a file named Module.symvers will be - generated. Module.symvers contains all exported symbols from - the kernel and compiled modules. For each symbol, the - corresponding CRC value is also stored. - - The syntax of the Module.symvers file is: - - - 0x2d036834 scsi_remove_host drivers/scsi/scsi_mod - - For a kernel build without CONFIG_MODVERSIONS enabled, the CRC - would read 0x00000000. - - Module.symvers serves two purposes: - 1) It lists all exported symbols from vmlinux and all modules. - 2) It lists the CRC if CONFIG_MODVERSIONS is enabled. - ---- 6.2 Symbols and External Modules - - When building an external module, the build system needs access - to the symbols from the kernel to check if all external symbols - are defined.

Note: the vmcoreinfo.rst has one very long title on one of its sub-sections: PG_lru|PG_private|PG_swapcache|PG_swapbacked|PG_slab|PG_hwpoision|PG_head_mask|PAGE_BUDDY_MAPCOUNT_VALUE(~PG_buddy)|PAGE_OFFLINE_MAPCOUNT_VALUE(~PG_offline) I opted to break this one, into two entries with the same content, in order to make it easier to display after being parsed in html and PDF. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

The system kernel's memory image is preserved across +the reboot and is accessible to the dump-capture kernel. + +You can use common commands, such as cp and scp, to copy the +memory image to a dump file on the local disk, or across the network to +a remote system. + +Kdump and kexec are currently supported on the x86, x86_64, ppc64, ia64, +s390x, arm and arm64 architectures. + +When the system kernel boots, it reserves a small section of memory for +the dump-capture kernel. This ensures that ongoing Direct Memory Access +(DMA) from the system kernel does not corrupt the dump-capture kernel. +The kexec -p command loads the dump-capture kernel into this reserved +memory. + +On x86 machines, the first 640 KB of physical memory is needed to boot, +regardless of where the kernel loads. Therefore, kexec backs up this +region just before rebooting into the dump-capture kernel. + +Similarly on PPC64 machines first 32KB of physical memory is needed for +booting regardless of where the kernel is loaded and to support 64K page +size kexec backs up the first 64KB memory. + +For s390x, when kdump is triggered, the crashkernel region is exchanged +with the region [0, crashkernel region size] and then the kdump kernel +runs in [0, crashkernel region size]. Therefore no relocatable kernel is +needed for s390x. + +All of the necessary information about the system kernel's core image is +encoded in the ELF format, and stored in a reserved area of memory +before a crash. The physical address of the start of the ELF header is +passed to the dump-capture kernel through the elfcorehdr= boot +parameter. Optionally the size of the ELF header can also be passed +when using the elfcorehdr=[size[KMG]@]offset[KMG] syntax. + + +With the dump-capture kernel, you can access the memory image through +/proc/vmcore. This exports the dump as an ELF-format file that you can +write out using file copy commands such as cp or scp.

For example, + "crashkernel=64M@16M" tells the system kernel to reserve 64 MB of memory + starting at physical address 0x01000000 (16MB) for the dump-capture kernel. + + On x86 and x86_64, use "crashkernel=64M@16M". + + On ppc64, use "crashkernel=128M@32M". + + On ia64, 256M@256M is a generous value that typically works. + The region may be automatically placed on ia64, see the + dump-capture kernel config option notes above. + If use sparse memory, the size should be rounded to GRANULE boundaries. + + On s390x, typically use "crashkernel=xxM". The value of xx is dependent + on the memory consumption of the kdump system. In general this is not + dependent on the memory size of the production system. + + On arm, the use of "crashkernel=Y@X" is no longer necessary; the + kernel will automatically locate the crash kernel image within the + first 512MB of RAM if X is not given. + + On arm64, use "crashkernel=Y[@X]". Note that the start address of + the kernel, X if explicitly specified, must be aligned to 2MiB (0x200000). + +Load the Dump-capture Kernel +============================ + +After booting to the system kernel, dump-capture kernel needs to be +loaded. + +Based on the architecture and type of image (relocatable or not), one +can choose to load the uncompressed vmlinux or compressed bzImage/vmlinuz +of dump-capture kernel.

On i386, kexec automatically checks if + the physical RAM size exceeds the 4 GB limit and if not, uses ELF32. + So, on non-PAE systems, ELF32 is always used. + + The --elf32-core-headers option can be used to force the generation of ELF32 + headers. This is necessary because GDB currently cannot open vmcore files + with ELF64 headers on 32-bit systems. + +* The "irqpoll" boot parameter reduces driver initialization failures + due to shared interrupts in the dump-capture kernel. + +* You must specify in the format corresponding to the root + device name in the output of mount command. + +* Boot parameter "1" boots the dump-capture kernel into single-user + mode without networking. If you want networking, use "3". + +* We generally don't have to bring up a SMP kernel just to capture the + dump. Hence generally it is useful either to build a UP dump-capture + kernel or specify maxcpus=1 option while loading dump-capture kernel. + Note, though maxcpus always works, you had better replace it with + nr_cpus to save memory if supported by the current ARCH, such as x86. + +* You should enable multi-cpu support in dump-capture kernel if you intend + to use multi-thread programs with it, such as parallel dump feature of + makedumpfile. Otherwise, the multi-thread program may have a great + performance degradation. To enable multi-cpu support, you should bring up an + SMP dump-capture kernel and specify maxcpus/nr_cpus, disable_cpu_apicid=[X] + options while loading it. + +* For s390x there are two kdump modes: If a ELF header is specified with + the elfcorehdr= kernel parameter, it is used by the kdump kernel as it + is done on all other architectures. If no elfcorehdr= kernel parameter is + specified, the s390x kdump kernel dynamically creates the header. The + second mode has the advantage that for CPU and memory hotplug, kdump has + not to be reloaded with kexec_load(). + +* For s390x systems with many attached devices the "cio_ignore" kernel + parameter should be used for the kdump kernel in order to prevent allocation + of kernel memory for devices that are not relevant for kdump. The same + applies to systems that use SCSI/FCP devices. In that case the + "allow_lun_scan" zfcp module parameter should be set to zero before + setting FCP devices online. + +Kernel Panic +============ + +After successfully loading the dump-capture kernel as previously +described, the system will reboot into the dump-capture kernel if a +system crash is triggered. Trigger points are located in panic(), +die(), die_nmi() and in the sysrq handler (ALT-SysRq-c). + +The following conditions will execute a crash trigger point: + +If a hard lockup is detected and "NMI watchdog" is configured, the system +will boot into the dump-capture kernel ( die_nmi() ). + +If die() is called, and it happens to be a thread with pid 0 or 1, or die() +is called inside interrupt context or die() is called and panic_on_oops is set, +the system will boot into the dump-capture kernel. + +On powerpc systems when a soft-reset is generated, die() is called by all cpus +and the system will boot into the dump-capture kernel. + +For testing purposes, you can trigger a crash by using "ALT-SysRq-c", +"echo c > /proc/sysrq-trigger" or write a module to force the panic. + +Write Out the Dump File +======================= + +After the dump-capture kernel is booted, write out the dump file with +the following command:: + + cp /proc/vmcore + + +Analysis +======== + +Before analyzing the dump image, you should reboot into a stable kernel. + +You can do limited analysis using GDB on the dump file copied out of +/proc/vmcore. Use the debug vmlinux built with -g and run the following +command:: + + gdb vmlinux + +Stack trace for the task on processor 0, register display, and memory +display work fine. + +Note: GDB cannot analyze core files generated in ELF64 format for x86. +On systems with a maximum of 4GB of memory, you can generate +ELF32-format headers using the --elf32-core-headers kernel option on the +dump kernel. + +You can also use the Crash utility to analyze dump files in Kdump +format. Crash is available on Dave Anderson's site at the following URL: + + http://people.redhat.com/~anderson/ + +Trigger Kdump on WARN() +======================= + +The kernel parameter, panic_on_warn, calls panic() in all WARN() paths.

DO NOT add this kernel - to the boot loader configuration files. - -Dump-capture kernel config options (Arch Dependent, ppc64) ----------------------------------------------------------- - -1) Enable "Build a kdump crash kernel" support under "Kernel" options: - - CONFIG_CRASH_DUMP=y - -2) Enable "Build a relocatable kernel" support - - CONFIG_RELOCATABLE=y - - Make and install the kernel and its modules. - -Dump-capture kernel config options (Arch Dependent, ia64) ----------------------------------------------------------- - -- No specific options are required to create a dump-capture kernel - for ia64, other than those specified in the arch independent section - above. This means that it is possible to use the system kernel - as a dump-capture kernel if desired. - - The crashkernel region can be automatically placed by the system - kernel at run time. This is done by specifying the base address as 0, - or omitting it all together. - - crashkernel=256M@0 - or - crashkernel=256M - - If the start address is specified, note that the start address of the - kernel will be aligned to 64Mb, so if the start address is not then - any space below the alignment point will be wasted. - -Dump-capture kernel config options (Arch Dependent, arm) ----------------------------------------------------------- - -- To use a relocatable kernel, - Enable "AUTO_ZRELADDR" support under "Boot" options: - - AUTO_ZRELADDR=y - -Dump-capture kernel config options (Arch Dependent, arm64) ----------------------------------------------------------- - -- Please note that kvm of the dump-capture kernel will not be enabled - on non-VHE systems even if it is configured. This is because the CPU - will not be reset to EL2 on panic. - -Extended crashkernel syntax -=========================== - -While the "crashkernel=size[@offset]" syntax is sufficient for most -configurations, sometimes it's handy to have the reserved memory dependent -on the value of System RAM -- that's mostly for distributors that pre-setup -the kernel command line to avoid a unbootable system after some memory has -been removed from the machine. - -The syntax is: - - crashkernel=:[,:,...][@offset] - range=start-[end] - -For example: - - crashkernel=512M-2G:64M,2G-:128M - -This would mean: - - 1) if the RAM is smaller than 512M, then don't reserve anything - (this is the "rescue" case) - 2) if the RAM size is between 512M and 2G (exclusive), then reserve 64M - 3) if the RAM size is larger than 2G, then reserve 128M - - - -Boot into System Kernel -======================= - -1) Update the boot loader (such as grub, yaboot, or lilo) configuration - files as necessary. - -2) Boot the system kernel with the boot parameter "crashkernel=Y@X", - where Y specifies how much memory to reserve for the dump-capture kernel - and X specifies the beginning of this reserved memory. For example, - "crashkernel=64M@16M" tells the system kernel to reserve 64 MB of memory - starting at physical address 0x01000000 (16MB) for the dump-capture kernel. - - On x86 and x86_64, use "crashkernel=64M@16M". - - On ppc64, use "crashkernel=128M@32M". - - On ia64, 256M@256M is a generous value that typically works. - The region may be automatically placed on ia64, see the - dump-capture kernel config option notes above. - If use sparse memory, the size should be rounded to GRANULE boundaries. - - On s390x, typically use "crashkernel=xxM". The value of xx is dependent - on the memory consumption of the kdump system. In general this is not - dependent on the memory size of the production system. - - On arm, the use of "crashkernel=Y@X" is no longer necessary; the - kernel will automatically locate the crash kernel image within the - first 512MB of RAM if X is not given. - - On arm64, use "crashkernel=Y[@X]". Note that the start address of - the kernel, X if explicitly specified, must be aligned to 2MiB (0x200000). - -Load the Dump-capture Kernel -============================ - -After booting to the system kernel, dump-capture kernel needs to be -loaded. - -Based on the architecture and type of image (relocatable or not), one -can choose to load the uncompressed vmlinux or compressed bzImage/vmlinuz -of dump-capture kernel. Following is the summary. - -For i386 and x86_64: - - Use vmlinux if kernel is not relocatable. - - Use bzImage/vmlinuz if kernel is relocatable. -For ppc64: - - Use vmlinux -For ia64: - - Use vmlinux or vmlinuz.gz -For s390x: - - Use image or bzImage -For arm: - - Use zImage -For arm64: - - Use vmlinux or Image - -If you are using an uncompressed vmlinux image then use following command -to load dump-capture kernel. - - kexec -p \ - --initrd= --args-linux \ - --append="root= " - -If you are using a compressed bzImage/vmlinuz, then use following command -to load dump-capture kernel. - - kexec -p \ - --initrd= \ - --append="root= " - -If you are using a compressed zImage, then use following command -to load dump-capture kernel. - - kexec --type zImage -p \ - --initrd= \ - --dtb= \ - --append="root= " - -If you are using an uncompressed Image, then use following command -to load dump-capture kernel. - - kexec -p \ - --initrd= \ - --append="root= " - -Please note, that --args-linux does not need to be specified for ia64. -It is planned to make this a no-op on that architecture, but for now -it should be omitted - -Following are the arch specific command line options to be used while -loading dump-capture kernel. - -For i386, x86_64 and ia64: - "1 irqpoll maxcpus=1 reset_devices" - -For ppc64: - "1 maxcpus=1 noirqdistrib reset_devices" - -For s390x: - "1 maxcpus=1 cgroup_disable=memory" - -For arm: - "1 maxcpus=1 reset_devices" - -For arm64: - "1 maxcpus=1 reset_devices" - -Notes on loading the dump-capture kernel: - -* By default, the ELF headers are stored in ELF64 format to support - systems with more than 4GB memory. On i386, kexec automatically checks if - the physical RAM size exceeds the 4 GB limit and if not, uses ELF32. - So, on non-PAE systems, ELF32 is always used. - - The --elf32-core-headers option can be used to force the generation of ELF32 - headers. This is necessary because GDB currently cannot open vmcore files - with ELF64 headers on 32-bit systems. - -* The "irqpoll" boot parameter reduces driver initialization failures - due to shared interrupts in the dump-capture kernel. - -* You must specify in the format corresponding to the root - device name in the output of mount command. - -* Boot parameter "1" boots the dump-capture kernel into single-user - mode without networking. If you want networking, use "3". - -* We generally don't have to bring up a SMP kernel just to capture the - dump. Hence generally it is useful either to build a UP dump-capture - kernel or specify maxcpus=1 option while loading dump-capture kernel. - Note, though maxcpus always works, you had better replace it with - nr_cpus to save memory if supported by the current ARCH, such as x86. - -* You should enable multi-cpu support in dump-capture kernel if you intend - to use multi-thread programs with it, such as parallel dump feature of - makedumpfile. Otherwise, the multi-thread program may have a great - performance degradation. To enable multi-cpu support, you should bring up an - SMP dump-capture kernel and specify maxcpus/nr_cpus, disable_cpu_apicid=[X] - options while loading it. - -* For s390x there are two kdump modes: If a ELF header is specified with - the elfcorehdr= kernel parameter, it is used by the kdump kernel as it - is done on all other architectures. If no elfcorehdr= kernel parameter is - specified, the s390x kdump kernel dynamically creates the header. The - second mode has the advantage that for CPU and memory hotplug, kdump has - not to be reloaded with kexec_load(). - -* For s390x systems with many attached devices the "cio_ignore" kernel - parameter should be used for the kdump kernel in order to prevent allocation - of kernel memory for devices that are not relevant for kdump. The same - applies to systems that use SCSI/FCP devices. In that case the - "allow_lun_scan" zfcp module parameter should be set to zero before - setting FCP devices online. - -Kernel Panic -============ - -After successfully loading the dump-capture kernel as previously -described, the system will reboot into the dump-capture kernel if a -system crash is triggered. Trigger points are located in panic(), -die(), die_nmi() and in the sysrq handler (ALT-SysRq-c). - -The following conditions will execute a crash trigger point: - -If a hard lockup is detected and "NMI watchdog" is configured, the system -will boot into the dump-capture kernel ( die_nmi() ). - -If die() is called, and it happens to be a thread with pid 0 or 1, or die() -is called inside interrupt context or die() is called and panic_on_oops is set, -the system will boot into the dump-capture kernel. - -On powerpc systems when a soft-reset is generated, die() is called by all cpus -and the system will boot into the dump-capture kernel. - -For testing purposes, you can trigger a crash by using "ALT-SysRq-c", -"echo c > /proc/sysrq-trigger" or write a module to force the panic. - -Write Out the Dump File -======================= - -After the dump-capture kernel is booted, write out the dump file with -the following command: - - cp /proc/vmcore - - -Analysis -======== - -Before analyzing the dump image, you should reboot into a stable kernel. - -You can do limited analysis using GDB on the dump file copied out of -/proc/vmcore. Use the debug vmlinux built with -g and run the following -command: - - gdb vmlinux - -Stack trace for the task on processor 0, register display, and memory -display work fine. - -Note: GDB cannot analyze core files generated in ELF64 format for x86. -On systems with a maximum of 4GB of memory, you can generate -ELF32-format headers using the --elf32-core-headers kernel option on the -dump kernel. - -You can also use the Crash utility to analyze dump files in Kdump -format. Crash is available on Dave Anderson's site at the following URL: - - http://people.redhat.com/~anderson/ - -Trigger Kdump on WARN() -======================= - -The kernel parameter, panic_on_warn, calls panic() in all WARN() paths. This -will cause a kdump to occur at the panic() call. In cases where a user wants -to specify this during runtime, /proc/sys/kernel/panic_on_warn can be set to 1 -to achieve the same behaviour. - -Contact -======= - -Vivek Goyal (vgoyal@redhat.com) -Maneesh Soni (maneesh@in.ibm.com) - diff --git a/Documentation/kdump/vmcoreinfo.rst b/Documentation/kdump/vmcoreinfo.rst new file mode 100644 index 000000000000..007a6b86e0ee --- /dev/null +++ b/Documentation/kdump/vmcoreinfo.rst @@ -0,0 +1,488 @@ +========== +VMCOREINFO +========== + +What is it? +=========== + +VMCOREINFO is a special ELF note section.

Wysocki , GPL + +1. Testing hibernation (aka suspend to disk or STD) +=================================================== + +To check if hibernation works, you can try to hibernate in the "reboot" mode:: + + # echo reboot > /sys/power/disk + # echo disk > /sys/power/state + +and the system should create a hibernation image, reboot, resume and get back to +the command prompt where you have started the transition.

Thus, if your machine +fails to hibernate or resume in the "reboot" mode, you should try the +"platform" mode:: + + # echo platform > /sys/power/disk + # echo disk > /sys/power/state + +which is the default and recommended mode of hibernation. + +Unfortunately, the "platform" mode of hibernation does not work on some systems +with broken BIOSes.

Then, +there is the file /sys/power/pm_test that can be used to make the hibernation +core run in a test mode. There are 5 test modes available: + +freezer + - test the freezing of processes + +devices + - test the freezing of processes and suspending of devices + +platform + - test the freezing of processes, suspending of devices and platform + global control methods [1]_ + +processors + - test the freezing of processes, suspending of devices, platform + global control methods [1]_ and the disabling of nonboot CPUs + +core + - test the freezing of processes, suspending of devices, platform global + control methods\ [1]_, the disabling of nonboot CPUs and suspending + of platform/system devices + +.. [1] + + the platform global control methods are only available on ACPI systems + and are only tested if the hibernation mode is set to "platform" + +To use one of them it is necessary to write the corresponding string to +/sys/power/pm_test (eg. "devices" to test the freezing of processes and +suspending devices) and issue the standard hibernation commands. For example, +to use the "devices" test mode along with the "platform" mode of hibernation, +you should do the following:: + + # echo devices > /sys/power/pm_test + # echo platform > /sys/power/disk + # echo disk > /sys/power/state + +Then, the kernel will try to freeze processes, suspend devices, wait a few +seconds (5 by default, but configurable by the suspend.pm_test_delay module +parameter), resume devices and thaw processes. If "platform" is written to +/sys/power/pm_test , then after suspending devices the kernel will additionally +invoke the global control methods (eg. ACPI global control methods) used to +prepare the platform firmware for hibernation. Next, it will wait a +configurable number of seconds and invoke the platform (eg. ACPI) global +methods used to cancel hibernation etc. + +Writing "none" to /sys/power/pm_test causes the kernel to switch to the normal +hibernation/suspend operations. Also, when open for reading, /sys/power/pm_test +contains a space-separated list of all available tests (including "none" that +represents the normal functionality) in which the current test level is +indicated by square brackets. + +Generally, as you can see, each test level is more "invasive" than the previous +one and the "core" level tests the hardware and drivers as deeply as possible +without creating a hibernation image. Obviously, if the "devices" test fails, +the "platform" test will fail as well and so on. Thus, as a rule of thumb, you +should try the test modes starting from "freezer", through "devices", "platform" +and "processors" up to "core" (repeat the test on each level a couple of times +to make sure that any random factors are avoided). + +If the "freezer" test fails, there is a task that cannot be frozen (in that case +it usually is possible to identify the offending task by analysing the output of +dmesg obtained after the failing test). Failure at this level usually means +that there is a problem with the tasks freezer subsystem that should be +reported. + +If the "devices" test fails, most likely there is a driver that cannot suspend +or resume its device (in the latter case the system may hang or become unstable +after the test, so please take that into consideration). To find this driver, +you can carry out a binary search according to the rules: + +- if the test fails, unload a half of the drivers currently loaded and repeat + (that would probably involve rebooting the system, so always note what drivers + have been loaded before the test), +- if the test succeeds, load a half of the drivers you have unloaded most + recently and repeat. + +Once you have found the failing driver (there can be more than just one of +them), you have to unload it every time before hibernation. In that case please +make sure to report the problem with the driver. + +It is also possible that the "devices" test will still fail after you have +unloaded all modules. In that case, you may want to look in your kernel +configuration for the drivers that can be compiled as modules (and test again +with these drivers compiled as modules). You may also try to use some special +kernel command line options such as "noapic", "noacpi" or even "acpi=off". + +If the "platform" test fails, there is a problem with the handling of the +platform (eg. ACPI) firmware on your system. In that case the "platform" mode +of hibernation is not likely to work. You can try the "shutdown" mode, but that +is rather a poor man's workaround. + +If the "processors" test fails, the disabling/enabling of nonboot CPUs does not +work (of course, this only may be an issue on SMP systems) and the problem +should be reported. In that case you can also try to switch the nonboot CPUs +off and on using the /sys/devices/system/cpu/cpu*/online sysfs attributes and +see if that works. + +If the "core" test fails, which means that suspending of the system/platform +devices has failed (these devices are suspended on one CPU with interrupts off), +the problem is most probably hardware-related and serious, so it should be +reported. + +A failure of any of the "platform", "processors" or "core" tests may cause your +system to hang or become unstable, so please beware. Such a failure usually +indicates a serious problem that very well may be related to the hardware, but +please report it anyway. + +b) Testing minimal configuration +-------------------------------- + +If all of the hibernation test modes work, you can boot the system with the +"init=/bin/bash" command line parameter and attempt to hibernate in the +"reboot", "shutdown" and "platform" modes. If that does not work, there +probably is a problem with a driver statically compiled into the kernel and you +can try to compile more drivers as modules, so that they can be tested +individually. Otherwise, there is a problem with a modular driver and you can +find it by loading a half of the modules you normally use and binary searching +in accordance with the algorithm: +- if there are n modules loaded and the attempt to suspend and resume fails, +unload n/2 of the modules and try again (that would probably involve rebooting +the system), +- if there are n modules loaded and the attempt to suspend and resume succeeds, +load n/2 modules more and try again. + +Again, if you find the offending module(s), it(they) must be unloaded every time +before hibernation, and please report the problem with it(them). + +c) Using the "test_resume" hibernation option +--------------------------------------------- + +/sys/power/disk generally tells the kernel what to do after creating a +hibernation image. One of the available options is "test_resume" which +causes the just created image to be used for immediate restoration. Namely, +after doing:: + + # echo test_resume > /sys/power/disk + # echo disk > /sys/power/state + +a hibernation image will be created and a resume from it will be triggered +immediately without involving the platform firmware in any way. + +That test can be used to check if failures to resume from hibernation are +related to bad interactions with the platform firmware. That is, if the above +works every time, but resume from actual hibernation does not work or is +unreliable, the platform firmware may be responsible for the failures. + +On architectures and platforms that support using different kernels to restore +hibernation images (that is, the kernel used to read the image from storage and +load it into memory is different from the one included in the image) or support +kernel address space randomization, it also can be used to check if failures +to resume may be related to the differences between the restore and image +kernels. + +d) Advanced debugging +--------------------- + +In case that hibernation does not work on your system even in the minimal +configuration and compiling more drivers as modules is not practical or some +modules cannot be unloaded, you can use one of the more advanced debugging +techniques to find the problem. First, if there is a serial port in your box, +you can boot the kernel with the 'no_console_suspend' parameter and try to log +kernel messages using the serial console. This may provide you with some +information about the reasons of the suspend (resume) failure. Alternatively, +it may be possible to use a FireWire port for debugging with firescope +(http://v3.sk/~lkundrak/firescope/).

They +should be unloaded every time before an STR transition. + +Next, you can follow the instructions at S2RAM_LINK to test the system, but if +it does not work "out of the box", you may need to boot it with +"init=/bin/bash" and test s2ram in the minimal configuration. In that case, +you may be able to search for failing drivers by following the procedure +analogous to the one described in section 1. If you find some failing drivers, +you will have to unload them every time before an STR transition (ie. before +you run s2ram), and please report the problems with them. + +There is a debugfs entry which shows the suspend to RAM statistics.

If there are multiple +batteries with their own chargers acting independently in a system, +the system may need multiple instances of Charger Manager. + +1. Introduction +=============== + +Charger Manager supports the following: + +* Support for multiple chargers (e.g., a device with USB, AC, and solar panels) + A system may have multiple chargers (or power sources) and some of + they may be activated at the same time. Each charger may have its + own power-supply-class and each power-supply-class can provide + different information about the battery status. This framework + aggregates charger-related information from multiple sources and + shows combined information as a single power-supply-class. + +* Support for in suspend-to-RAM polling (with suspend_again callback) + While the battery is being charged and the system is in suspend-to-RAM, + we may need to monitor the battery health by looking at the ambient or + battery temperature. We can accomplish this by waking up the system + periodically. However, such a method wakes up devices unnecessarily for + monitoring the battery health and tasks, and user processes that are + supposed to be kept suspended. That, in turn, incurs unnecessary power + consumption and slow down charging process. Or even, such peak power + consumption can stop chargers in the middle of charging + (external power input < device power consumption), which not + only affects the charging time, but the lifespan of the battery. + + Charger Manager provides a function "cm_suspend_again" that can be + used as suspend_again callback of platform_suspend_ops. If the platform + requires tasks other than cm_suspend_again, it may implement its own + suspend_again callback that calls cm_suspend_again in the middle. + Normally, the platform will need to resume and suspend some devices + that are used by Charger Manager. + +* Support for premature full-battery event handling + If the battery voltage drops by "fullbatt_vchkdrop_uV" after + "fullbatt_vchkdrop_ms" from the full-battery event, the framework + restarts charging. This check is also performed while suspended by + setting wakeup time accordingly and using suspend_again. + +* Support for uevent-notify + With the charger-related events, the device sends + notification to users with UEVENT. + +2. Global Charger-Manager Data related with suspend_again +========================================================= +In order to setup Charger Manager with suspend-again feature +(in-suspend monitoring), the user should provide charger_global_desc +with setup_charger_manager(`struct charger_global_desc *`). +This charger_global_desc data for in-suspend monitoring is global +as the name suggests. Thus, the user needs to provide only once even +if there are multiple batteries. If there are multiple batteries, the +multiple instances of Charger Manager share the same charger_global_desc +and it will manage in-suspend monitoring for all instances of Charger Manager. + +The user needs to provide all the three entries to `struct charger_global_desc` +properly in order to activate in-suspend monitoring: + +`char *rtc_name;` + The name of rtc (e.g., "rtc0") used to wakeup the system from + suspend for Charger Manager. The alarm interrupt (AIE) of the rtc + should be able to wake up the system from suspend. Charger Manager + saves and restores the alarm value and use the previously-defined + alarm if it is going to go off earlier than Charger Manager so that + Charger Manager does not interfere with previously-defined alarms. + +`bool (*rtc_only_wakeup)(void);` + This callback should let CM know whether + the wakeup-from-suspend is caused only by the alarm of "rtc" in the + same struct. If there is any other wakeup source triggered the + wakeup, it should return false. If the "rtc" is the only wakeup + reason, it should return true. + +`bool assume_timer_stops_in_suspend;` + if true, Charger Manager assumes that + the timer (CM uses jiffies as timer) stops during suspend. Then, CM + assumes that the suspend-duration is same as the alarm length. + + +3. How to setup suspend_again +============================= +Charger Manager provides a function "extern bool cm_suspend_again(void)". +When cm_suspend_again is called, it monitors every battery.

If there are multiple -batteries with their own chargers acting independently in a system, -the system may need multiple instances of Charger Manager. - -1. Introduction -=============== - -Charger Manager supports the following: - -* Support for multiple chargers (e.g., a device with USB, AC, and solar panels) - A system may have multiple chargers (or power sources) and some of - they may be activated at the same time. Each charger may have its - own power-supply-class and each power-supply-class can provide - different information about the battery status. This framework - aggregates charger-related information from multiple sources and - shows combined information as a single power-supply-class. - -* Support for in suspend-to-RAM polling (with suspend_again callback) - While the battery is being charged and the system is in suspend-to-RAM, - we may need to monitor the battery health by looking at the ambient or - battery temperature. We can accomplish this by waking up the system - periodically. However, such a method wakes up devices unnecessarily for - monitoring the battery health and tasks, and user processes that are - supposed to be kept suspended. That, in turn, incurs unnecessary power - consumption and slow down charging process. Or even, such peak power - consumption can stop chargers in the middle of charging - (external power input < device power consumption), which not - only affects the charging time, but the lifespan of the battery. - - Charger Manager provides a function "cm_suspend_again" that can be - used as suspend_again callback of platform_suspend_ops. If the platform - requires tasks other than cm_suspend_again, it may implement its own - suspend_again callback that calls cm_suspend_again in the middle. - Normally, the platform will need to resume and suspend some devices - that are used by Charger Manager. - -* Support for premature full-battery event handling - If the battery voltage drops by "fullbatt_vchkdrop_uV" after - "fullbatt_vchkdrop_ms" from the full-battery event, the framework - restarts charging. This check is also performed while suspended by - setting wakeup time accordingly and using suspend_again. - -* Support for uevent-notify - With the charger-related events, the device sends - notification to users with UEVENT. - -2. Global Charger-Manager Data related with suspend_again -======================================================== -In order to setup Charger Manager with suspend-again feature -(in-suspend monitoring), the user should provide charger_global_desc -with setup_charger_manager(struct charger_global_desc *). -This charger_global_desc data for in-suspend monitoring is global -as the name suggests. Thus, the user needs to provide only once even -if there are multiple batteries. If there are multiple batteries, the -multiple instances of Charger Manager share the same charger_global_desc -and it will manage in-suspend monitoring for all instances of Charger Manager. - -The user needs to provide all the three entries properly in order to activate -in-suspend monitoring: - -struct charger_global_desc { - -char *rtc_name; - : The name of rtc (e.g., "rtc0") used to wakeup the system from - suspend for Charger Manager. The alarm interrupt (AIE) of the rtc - should be able to wake up the system from suspend.

If there is any other wakeup source triggered the - wakeup, it should return false. If the "rtc" is the only wakeup - reason, it should return true. - -bool assume_timer_stops_in_suspend; - : if true, Charger Manager assumes that - the timer (CM uses jiffies as timer) stops during suspend. Then, CM - assumes that the suspend-duration is same as the alarm length. -}; - -3. How to setup suspend_again -============================= -Charger Manager provides a function "extern bool cm_suspend_again(void)". -When cm_suspend_again is called, it monitors every battery.

After this, it executes try_to_freeze_tasks() that sends a +fake signal to all user space processes, and wakes up all the kernel threads. +All freezable tasks must react to that by calling try_to_freeze(), which +results in a call to __refrigerator() (defined in kernel/freezer.c), which sets +the task's PF_FROZEN flag, changes its state to TASK_UNINTERRUPTIBLE and makes +it loop until PF_FROZEN is cleared for it. Then, we say that the task is +'frozen' and therefore the set of functions handling this mechanism is referred +to as 'the freezer' (these functions are defined in kernel/power/process.c, +kernel/freezer.c & include/linux/freezer.h). User space processes are generally +frozen before kernel threads. + +__refrigerator() must not be called directly. Instead, use the +try_to_freeze() function (defined in include/linux/freezer.h), that checks +if the task is to be frozen and makes the task enter __refrigerator(). + +For user space processes try_to_freeze() is called automatically from the +signal-handling code, but the freezable kernel threads need to call it +explicitly in suitable places or use the wait_event_freezable() or +wait_event_freezable_timeout() macros (defined in include/linux/freezer.h) +that combine interruptible sleep with checking if the task is to be frozen and +calling try_to_freeze(). The main loop of a freezable kernel thread may look +like the following one:: + + set_freezable(); + do { + hub_events(); + wait_event_freezable(khubd_wait, + !list_empty(&hub_event_list) || + kthread_should_stop()); + } while (!kthread_should_stop() || !list_empty(&hub_event_list)); + +(from drivers/usb/core/hub.c::hub_thread()). + +If a freezable kernel thread fails to call try_to_freeze() after the freezer has +initiated a freezing operation, the freezing of tasks will fail and the entire +hibernation operation will be cancelled. For this reason, freezable kernel +threads must call try_to_freeze() somewhere or use one of the +wait_event_freezable() and wait_event_freezable_timeout() macros. + +After the system memory state has been restored from a hibernation image and +devices have been reinitialized, the function thaw_processes() is called in +order to clear the PF_FROZEN flag for each frozen task. Then, the tasks that +have been frozen leave __refrigerator() and continue running. + + +Rationale behind the functions dealing with freezing and thawing of tasks +------------------------------------------------------------------------- + +freeze_processes(): + - freezes only userspace tasks + +freeze_kernel_threads(): + - freezes all tasks (including kernel threads) because we can't freeze + kernel threads without freezing userspace tasks + +thaw_kernel_threads(): + - thaws only kernel threads; this is particularly useful if we need to do + anything special in between thawing of kernel threads and thawing of + userspace tasks, or if we want to postpone the thawing of userspace tasks + +thaw_processes(): + - thaws all tasks (including kernel threads) because we can't thaw userspace + tasks without thawing kernel threads + + +III. Which kernel threads are freezable? +======================================== + +Kernel threads are not freezable by default. However, a kernel thread may clear +PF_NOFREEZE for itself by calling set_freezable() (the resetting of PF_NOFREEZE +directly is not allowed). From this point it is regarded as freezable +and must call try_to_freeze() in a suitable place. + +IV. Why do we do that? +====================== + +Generally speaking, there is a couple of reasons to use the freezing of tasks: + +1. The principal reason is to prevent filesystems from being damaged after + hibernation. At the moment we have no simple means of checkpointing + filesystems, so if there are any modifications made to filesystem data and/or + metadata on disks, we cannot bring them back to the state from before the + modifications. At the same time each hibernation image contains some + filesystem-related information that must be consistent with the state of the + on-disk data and metadata after the system memory state has been restored + from the image (otherwise the filesystems will be damaged in a nasty way, + usually making them almost impossible to repair). We therefore freeze + tasks that might cause the on-disk filesystems' data and metadata to be + modified after the hibernation image has been created and before the + system is finally powered off. The majority of these are user space + processes, but if any of the kernel threads may cause something like this + to happen, they have to be freezable. + +2. Next, to create the hibernation image we need to free a sufficient amount of + memory (approximately 50% of available RAM) and we need to do that before + devices are deactivated, because we generally need them for swapping out. + Then, after the memory for the image has been freed, we don't want tasks + to allocate additional memory and we prevent them from doing that by + freezing them earlier. [Of course, this also means that device drivers + should not allocate substantial amounts of memory from their .suspend() + callbacks before hibernation, but this is a separate issue.] + +3. The third reason is to prevent user space processes and some kernel threads + from interfering with the suspending and resuming of devices. A user space + process running on a second CPU while we are suspending devices may, for + example, be troublesome and without the freezing of tasks we would need some + safeguards against race conditions that might occur in such a case. + +Although Linus Torvalds doesn't like the freezing of tasks, he said this in one +of the discussions on LKML (http://lkml.org/lkml/2007/4/27/608): + +"RJW:> Why we freeze tasks at all or why we freeze kernel threads? + +Linus: In many ways, 'at all'. + +I **do** realize the IO request queue issues, and that we cannot actually do +s2ram with some devices in the middle of a DMA. So we want to be able to +avoid *that*, there's no question about that. And I suspect that stopping +user threads and then waiting for a sync is practically one of the easier +ways to do so. + +So in practice, the 'at all' may become a 'why freeze kernel threads?' and +freezing user threads I don't find really objectionable." + +Still, there are kernel threads that may want to be freezable. For example, if +a kernel thread that belongs to a device driver accesses the device directly, it +in principle needs to know when the device is suspended, so that it doesn't try +to access it at that time. However, if the kernel thread is freezable, it will +be frozen before the driver's .suspend() callback is executed and it will be +thawed after the driver's .resume() callback has run, so it won't be accessing +the device while it's suspended. + +4. Another reason for freezing tasks is to prevent user space processes from + realizing that hibernation (or suspend) operation takes place. Ideally, user + space processes should not notice that such a system-wide operation has + occurred and should continue running without any problems after the restore + (or resume from suspend). Unfortunately, in the most general case this + is quite difficult to achieve without the freezing of tasks. Consider, + for example, a process that depends on all CPUs being online while it's + running. Since we need to disable nonboot CPUs during the hibernation, + if this process is not frozen, it may notice that the number of CPUs has + changed and may start to work incorrectly because of that. + +V. Are there any problems related to the freezing of tasks? +=========================================================== + +Yes, there are. + +First of all, the freezing of kernel threads may be tricky if they depend one +on another. For example, if kernel thread A waits for a completion (in the +TASK_UNINTERRUPTIBLE state) that needs to be done by freezable kernel thread B +and B is frozen in the meantime, then A will be blocked until B is thawed, which +may be undesirable. That's why kernel threads are not freezable by default. + +Second, there are the following two problems related to the freezing of user +space processes: + +1. Putting processes into an uninterruptible sleep distorts the load average. +2. Now that we have FUSE, plus the framework for doing device drivers in + userspace, it gets even more complicated because some userspace processes are + now doing the sorts of things that kernel threads do + (https://lists.linux-foundation.org/pipermail/linux-pm/2007-May/012309.html). + +The problem 1. seems to be fixable, although it hasn't been fixed so far. The +other one is more serious, but it seems that we can work around it by using +hibernation (and suspend) notifiers (in that case, though, we won't be able to +avoid the realization by the user space processes that the hibernation is taking +place). + +There are also problems that the freezing of tasks tends to expose, although +they are not directly related to it. For example, if request_firmware() is +called from a device driver's .resume() routine, it will timeout and eventually +fail, because the user land process that should respond to the request is frozen +at this point. So, seemingly, the failure is due to the freezing of tasks. +Suppose, however, that the firmware file is located on a filesystem accessible +only through another device that hasn't been resumed yet. In that case, +request_firmware() will fail regardless of whether or not the freezing of tasks +is used. Consequently, the problem is not really related to the freezing of +tasks, since it generally exists anyway. + +A driver must have all firmwares it may need in RAM before suspend() is called. +If keeping them is not practical, for example due to their size, they must be +requested early enough using the suspend notifier API described in +Documentation/driver-api/pm/notifiers.rst. + +VI. Are there any precautions to be taken to prevent freezing failures? +======================================================================= + +Yes, there are. + +First of all, grabbing the 'system_transition_mutex' lock to mutually exclude a piece of code +from system-wide sleep such as suspend/hibernation is not encouraged. +If possible, that piece of code must instead hook onto the suspend/hibernation +notifiers to achieve mutual exclusion. Look at the CPU-Hotplug code +(kernel/cpu.c) for an example. + +However, if that is not feasible, and grabbing 'system_transition_mutex' is deemed necessary, +it is strongly discouraged to directly call mutex_[un]lock(&system_transition_mutex) since +that could lead to freezing failures, because if the suspend/hibernate code +successfully acquired the 'system_transition_mutex' lock, and hence that other entity failed +to acquire the lock, then that task would get blocked in TASK_UNINTERRUPTIBLE +state. As a consequence, the freezer would not be able to freeze that task, +leading to freezing failure. + +However, the [un]lock_system_sleep() APIs are safe to use in this scenario, +since they ask the freezer to skip freezing this task, since it is anyway +"frozen enough" as it is blocked on 'system_transition_mutex', which will be released +only after the entire suspend/hibernation sequence is complete. +So, to summarize, use [un]lock_system_sleep() instead of directly using +mutex_[un]lock(&system_transition_mutex). That would prevent freezing failures. + +V.

Introduction +=============== + +1.1 What is an Operating Performance Point (OPP)? +------------------------------------------------- + +Complex SoCs of today consists of a multiple sub-modules working in conjunction. +In an operational system executing varied use cases, not all modules in the SoC +need to function at their highest performing frequency all the time. To +facilitate this, sub-modules in a SoC are grouped into domains, allowing some +domains to run at lower voltage and frequency while other domains run at +voltage/frequency pairs that are higher. + +The set of discrete tuples consisting of frequency and voltage pairs that +the device will support per domain are called Operating Performance Points or +OPPs. + +As an example: + +Let us consider an MPU device which supports the following: +{300MHz at minimum voltage of 1V}, {800MHz at minimum voltage of 1.2V}, +{1GHz at minimum voltage of 1.3V} + +We can represent these as three OPPs as the following {Hz, uV} tuples: + +- {300000000, 1000000} +- {800000000, 1200000} +- {1000000000, 1300000} + +1.2 Operating Performance Points Library +---------------------------------------- + +OPP library provides a set of helper functions to organize and query the OPP +information. The library is located in drivers/base/power/opp.c and the header +is located in include/linux/pm_opp.h. OPP library can be enabled by enabling +CONFIG_PM_OPP from power management menuconfig menu. OPP library depends on +CONFIG_PM as certain SoCs such as Texas Instrument's OMAP framework allows to +optionally boot at a certain OPP without needing cpufreq. + +Typical usage of the OPP library is as follows:: + + (users) -> registers a set of default OPPs -> (library) + SoC framework -> modifies on required cases certain OPPs -> OPP layer + -> queries to search/retrieve information -> + +OPP layer expects each domain to be represented by a unique device pointer. SoC +framework registers a set of initial OPPs per device with the OPP layer. This +list is expected to be an optimally small number typically around 5 per device. +This initial list contains a set of OPPs that the framework expects to be safely +enabled by default in the system. + +Note on OPP Availability +^^^^^^^^^^^^^^^^^^^^^^^^ + +As the system proceeds to operate, SoC framework may choose to make certain +OPPs available or not available on each device based on various external +factors. Example usage: Thermal management or other exceptional situations where +SoC framework might choose to disable a higher frequency OPP to safely continue +operations until that OPP could be re-enabled if possible. + +OPP library facilitates this concept in it's implementation. The following +operational functions operate only on available opps: +opp_find_freq_{ceil, floor}, dev_pm_opp_get_voltage, dev_pm_opp_get_freq, dev_pm_opp_get_opp_count + +dev_pm_opp_find_freq_exact is meant to be used to find the opp pointer which can then +be used for dev_pm_opp_enable/disable functions to make an opp available as required. + +WARNING: Users of OPP library should refresh their availability count using +get_opp_count if dev_pm_opp_enable/disable functions are invoked for a device, the +exact mechanism to trigger these or the notification mechanism to other +dependent subsystems such as cpufreq are left to the discretion of the SoC +specific framework which uses the OPP library. Similar care needs to be taken +care to refresh the cpufreq table in cases of these operations. + +2. Initial OPP List Registration +================================ +The SoC implementation calls dev_pm_opp_add function iteratively to add OPPs per +device. It is expected that the SoC framework will register the OPP entries +optimally- typical numbers range to be less than 5. The list generated by +registering the OPPs is maintained by OPP library throughout the device +operation. The SoC framework can subsequently control the availability of the +OPPs dynamically using the dev_pm_opp_enable / disable functions. + +dev_pm_opp_add + Add a new OPP for a specific domain represented by the device pointer. + The OPP is defined using the frequency and voltage. Once added, the OPP + is assumed to be available and control of it's availability can be done + with the dev_pm_opp_enable/disable functions. OPP library internally stores + and manages this information in the opp struct. This function may be + used by SoC framework to define a optimal list as per the demands of + SoC usage environment. + + WARNING: + Do not use this function in interrupt context. + + Example:: + + soc_pm_init() + { + /* Do things */ + r = dev_pm_opp_add(mpu_dev, 1000000, 900000); + if (!r) { + pr_err("%s: unable to register mpu opp(%d)\n", r); + goto no_cpufreq; + } + /* Do cpufreq things */ + no_cpufreq: + /* Do remaining things */ + } + +3. OPP Search Functions +======================= +High level framework such as cpufreq operates on frequencies. To map the +frequency back to the corresponding OPP, OPP library provides handy functions +to search the OPP list that OPP library internally manages. These search +functions return the matching pointer representing the opp if a match is +found, else returns error. These errors are expected to be handled by standard +error checks such as IS_ERR() and appropriate actions taken by the caller. + +Callers of these functions shall call dev_pm_opp_put() after they have used the +OPP. Otherwise the memory for the OPP will never get freed and result in +memleak. + +dev_pm_opp_find_freq_exact + Search for an OPP based on an *exact* frequency and + availability. This function is especially useful to enable an OPP which + is not available by default. + Example: In a case when SoC framework detects a situation where a + higher frequency could be made available, it can use this function to + find the OPP prior to call the dev_pm_opp_enable to actually make + it available:: + + opp = dev_pm_opp_find_freq_exact(dev, 1000000000, false); + dev_pm_opp_put(opp); + /* dont operate on the pointer.. just do a sanity check.. */ + if (IS_ERR(opp)) { + pr_err("frequency not disabled!\n"); + /* trigger appropriate actions.. */ + } else { + dev_pm_opp_enable(dev,1000000000); + } + + NOTE: + This is the only search function that operates on OPPs which are + not available. + +dev_pm_opp_find_freq_floor + Search for an available OPP which is *at most* the + provided frequency. This function is useful while searching for a lesser + match OR operating on OPP information in the order of decreasing + frequency. + Example: To find the highest opp for a device:: + + freq = ULONG_MAX; + opp = dev_pm_opp_find_freq_floor(dev, &freq); + dev_pm_opp_put(opp); + +dev_pm_opp_find_freq_ceil + Search for an available OPP which is *at least* the + provided frequency. This function is useful while searching for a + higher match OR operating on OPP information in the order of increasing + frequency. + Example 1: To find the lowest opp for a device:: + + freq = 0; + opp = dev_pm_opp_find_freq_ceil(dev, &freq); + dev_pm_opp_put(opp); + + Example 2: A simplified implementation of a SoC cpufreq_driver->target:: + + soc_cpufreq_target(..) + { + /* Do stuff like policy checks etc. */ + /* Find the best frequency match for the req */ + opp = dev_pm_opp_find_freq_ceil(dev, &freq); + dev_pm_opp_put(opp); + if (!IS_ERR(opp)) + soc_switch_to_freq_voltage(freq); + else + /* do something when we can't satisfy the req */ + /* do other stuff */ + } + +4. OPP Availability Control Functions +===================================== +A default OPP list registered with the OPP library may not cater to all possible +situation. The OPP library provides a set of functions to modify the +availability of a OPP within the OPP list. This allows SoC frameworks to have +fine grained dynamic control of which sets of OPPs are operationally available. +These functions are intended to *temporarily* remove an OPP in conditions such +as thermal considerations (e.g. don't use OPPx until the temperature drops). + +WARNING: + Do not use these functions in interrupt context. + +dev_pm_opp_enable + Make a OPP available for operation. + Example: Lets say that 1GHz OPP is to be made available only if the + SoC temperature is lower than a certain threshold. The SoC framework + implementation might choose to do something as follows:: + + if (cur_temp < temp_low_thresh) { + /* Enable 1GHz if it was disabled */ + opp = dev_pm_opp_find_freq_exact(dev, 1000000000, false); + dev_pm_opp_put(opp); + /* just error check */ + if (!IS_ERR(opp)) + ret = dev_pm_opp_enable(dev, 1000000000); + else + goto try_something_else; + } + +dev_pm_opp_disable + Make an OPP to be not available for operation + Example: Lets say that 1GHz OPP is to be disabled if the temperature + exceeds a threshold value. The SoC framework implementation might + choose to do something as follows:: + + if (cur_temp > temp_high_thresh) { + /* Disable 1GHz if it was enabled */ + opp = dev_pm_opp_find_freq_exact(dev, 1000000000, true); + dev_pm_opp_put(opp); + /* just error check */ + if (!IS_ERR(opp)) + ret = dev_pm_opp_disable(dev, 1000000000); + else + goto try_something_else; + } + +5. OPP Data Retrieval Functions +=============================== +Since OPP library abstracts away the OPP information, a set of functions to pull +information from the OPP structure is necessary. Once an OPP pointer is +retrieved using the search functions, the following functions can be used by SoC +framework to retrieve the information represented inside the OPP layer. + +dev_pm_opp_get_voltage + Retrieve the voltage represented by the opp pointer. + Example: At a cpufreq transition to a different frequency, SoC + framework requires to set the voltage represented by the OPP using + the regulator framework to the Power Management chip providing the + voltage:: + + soc_switch_to_freq_voltage(freq) + { + /* do things */ + opp = dev_pm_opp_find_freq_ceil(dev, &freq); + v = dev_pm_opp_get_voltage(opp); + dev_pm_opp_put(opp); + if (v) + regulator_set_voltage(.., v); + /* do other things */ + } + +dev_pm_opp_get_freq + Retrieve the freq represented by the opp pointer. + Example: Lets say the SoC framework uses a couple of helper functions + we could pass opp pointers instead of doing additional parameters to + handle quiet a bit of data parameters:: + + soc_cpufreq_target(..) + { + /* do things.. */ + max_freq = ULONG_MAX; + max_opp = dev_pm_opp_find_freq_floor(dev,&max_freq); + requested_opp = dev_pm_opp_find_freq_ceil(dev,&freq); + if (!IS_ERR(max_opp) && !IS_ERR(requested_opp)) + r = soc_test_validity(max_opp, requested_opp); + dev_pm_opp_put(max_opp); + dev_pm_opp_put(requested_opp); + /* do other things */ + } + soc_test_validity(..) + { + if(dev_pm_opp_get_voltage(max_opp) < dev_pm_opp_get_voltage(requested_opp)) + return -EINVAL; + if(dev_pm_opp_get_freq(max_opp) < dev_pm_opp_get_freq(requested_opp)) + return -EINVAL; + /* do things.. */ + } + +dev_pm_opp_get_opp_count + Retrieve the number of available opps for a device + Example: Lets say a co-processor in the SoC needs to know the available + frequencies in a table, the main processor can notify as following:: + + soc_notify_coproc_available_frequencies() + { + /* Do things */ + num_available = dev_pm_opp_get_opp_count(dev); + speeds = kzalloc(sizeof(u32) * num_available, GFP_KERNEL); + /* populate the table in increasing order */ + freq = 0; + while (!IS_ERR(opp = dev_pm_opp_find_freq_ceil(dev, &freq))) { + speeds[i] = freq; + freq++; + i++; + dev_pm_opp_put(opp); + } + + soc_notify_coproc(AVAILABLE_FREQs, speeds, num_available); + /* Do other things */ + } + +6.

Hardware and Platform Support for PCI Power Management +========================================================= + +1.1. Native and Platform-Based Power Management +----------------------------------------------- + +In general, power management is a feature allowing one to save energy by putting +devices into states in which they draw less power (low-power states) at the +price of reduced functionality or performance. + +Usually, a device is put into a low-power state when it is underutilized or +completely inactive. However, when it is necessary to use the device once +again, it has to be put back into the "fully functional" state (full-power +state). This may happen when there are some data for the device to handle or +as a result of an external event requiring the device to be active, which may +be signaled by the device itself. + +PCI devices may be put into low-power states in two ways, by using the device +capabilities introduced by the PCI Bus Power Management Interface Specification, +or with the help of platform firmware, such as an ACPI BIOS. In the first +approach, that is referred to as the native PCI power management (native PCI PM) +in what follows, the device power state is changed as a result of writing a +specific value into one of its standard configuration registers. The second +approach requires the platform firmware to provide special methods that may be +used by the kernel to change the device's power state. + +Devices supporting the native PCI PM usually can generate wakeup signals called +Power Management Events (PMEs) to let the kernel know about external events +requiring the device to be active. After receiving a PME the kernel is supposed +to put the device that sent it into the full-power state. However, the PCI Bus +Power Management Interface Specification doesn't define any standard method of +delivering the PME from the device to the CPU and the operating system kernel. +It is assumed that the platform firmware will perform this task and therefore, +even though a PCI device is set up to generate PMEs, it also may be necessary to +prepare the platform firmware for notifying the CPU of the PMEs coming from the +device (e.g. by generating interrupts). + +In turn, if the methods provided by the platform firmware are used for changing +the power state of a device, usually the platform also provides a method for +preparing the device to generate wakeup signals. In that case, however, it +often also is necessary to prepare the device for generating PMEs using the +native PCI PM mechanism, because the method provided by the platform depends on +that. + +Thus in many situations both the native and the platform-based power management +mechanisms have to be used simultaneously to obtain the desired result. + +1.2. Native PCI Power Management +-------------------------------- + +The PCI Bus Power Management Interface Specification (PCI PM Spec) was +introduced between the PCI 2.1 and PCI 2.2 Specifications. It defined a +standard interface for performing various operations related to power +management. + +The implementation of the PCI PM Spec is optional for conventional PCI devices, +but it is mandatory for PCI Express devices. If a device supports the PCI PM +Spec, it has an 8 byte power management capability field in its PCI +configuration space. This field is used to describe and control the standard +features related to the native PCI power management. + +The PCI PM Spec defines 4 operating states for devices (D0-D3) and for buses +(B0-B3). The higher the number, the less power is drawn by the device or bus +in that state. However, the higher the number, the longer the latency for +the device or bus to return to the full-power state (D0 or B0, respectively). + +There are two variants of the D3 state defined by the specification. The first +one is D3hot, referred to as the software accessible D3, because devices can be +programmed to go into it. The second one, D3cold, is the state that PCI devices +are in when the supply voltage (Vcc) is removed from them. It is not possible +to program a PCI device to go into D3cold, although there may be a programmable +interface for putting the bus the device is on into a state in which Vcc is +removed from all devices on the bus. + +PCI bus power management, however, is not supported by the Linux kernel at the +time of this writing and therefore it is not covered by this document. + +Note that every PCI device can be in the full-power state (D0) or in D3cold, +regardless of whether or not it implements the PCI PM Spec. In addition to +that, if the PCI PM Spec is implemented by the device, it must support D3hot +as well as D0. The support for the D1 and D2 power states is optional. + +PCI devices supporting the PCI PM Spec can be programmed to go to any of the +supported low-power states (except for D3cold). While in D1-D3hot the +standard configuration registers of the device must be accessible to software +(i.e. the device is required to respond to PCI configuration accesses), although +its I/O and memory spaces are then disabled. This allows the device to be +programmatically put into D0. Thus the kernel can switch the device back and +forth between D0 and the supported low-power states (except for D3cold) and the +possible power state transitions the device can undergo are the following: + ++----------------------------+ +| Current State | New State | ++----------------------------+ +| D0 | D1, D2, D3 | ++----------------------------+ +| D1 | D2, D3 | ++----------------------------+ +| D2 | D3 | ++----------------------------+ +| D1, D2, D3 | D0 | ++----------------------------+ + +The transition from D3cold to D0 occurs when the supply voltage is provided to +the device (i.e. power is restored). In that case the device returns to D0 with +a full power-on reset sequence and the power-on defaults are restored to the +device by hardware just as at initial power up. + +PCI devices supporting the PCI PM Spec can be programmed to generate PMEs +while in a low-power state (D1-D3), but they are not required to be capable +of generating PMEs from all supported low-power states. In particular, the +capability of generating PMEs from D3cold is optional and depends on the +presence of additional voltage (3.3Vaux) allowing the device to remain +sufficiently active to generate a wakeup signal. + +1.3. ACPI Device Power Management +--------------------------------- + +The platform firmware support for the power management of PCI devices is +system-specific. However, if the system in question is compliant with the +Advanced Configuration and Power Interface (ACPI) Specification, like the +majority of x86-based systems, it is supposed to implement device power +management interfaces defined by the ACPI standard. + +For this purpose the ACPI BIOS provides special functions called "control +methods" that may be executed by the kernel to perform specific tasks, such as +putting a device into a low-power state. These control methods are encoded +using special byte-code language called the ACPI Machine Language (AML) and +stored in the machine's BIOS. The kernel loads them from the BIOS and executes +them as needed using an AML interpreter that translates the AML byte code into +computations and memory or I/O space accesses. This way, in theory, a BIOS +writer can provide the kernel with a means to perform actions depending +on the system design in a system-specific fashion. + +ACPI control methods may be divided into global control methods, that are not +associated with any particular devices, and device control methods, that have +to be defined separately for each device supposed to be handled with the help of +the platform. This means, in particular, that ACPI device control methods can +only be used to handle devices that the BIOS writer knew about in advance. The +ACPI methods used for device power management fall into that category. + +The ACPI specification assumes that devices can be in one of four power states +labeled as D0, D1, D2, and D3 that roughly correspond to the native PCI PM +D0-D3 states (although the difference between D3hot and D3cold is not taken +into account by ACPI). Moreover, for each power state of a device there is a +set of power resources that have to be enabled for the device to be put into +that state. These power resources are controlled (i.e. enabled or disabled) +with the help of their own control methods, _ON and _OFF, that have to be +defined individually for each of them. + +To put a device into the ACPI power state Dx (where x is a number between 0 and +3 inclusive) the kernel is supposed to (1) enable the power resources required +by the device in this state using their _ON control methods and (2) execute the +_PSx control method defined for the device. In addition to that, if the device +is going to be put into a low-power state (D1-D3) and is supposed to generate +wakeup signals from that state, the _DSW (or _PSW, replaced with _DSW by ACPI +3.0) control method defined for it has to be executed before _PSx. Power +resources that are not required by the device in the target power state and are +not required any more by any other device should be disabled (by executing their +_OFF control methods). If the current power state of the device is D3, it can +only be put into D0 this way. + +However, quite often the power states of devices are changed during a +system-wide transition into a sleep state or back into the working state. ACPI +defines four system sleep states, S1, S2, S3, and S4, and denotes the system +working state as S0. In general, the target system sleep (or working) state +determines the highest power (lowest number) state the device can be put +into and the kernel is supposed to obtain this information by executing the +device's _SxD control method (where x is a number between 0 and 4 inclusive). +If the device is required to wake up the system from the target sleep state, the +lowest power (highest number) state it can be put into is also determined by the +target state of the system. The kernel is then supposed to use the device's +_SxW control method to obtain the number of that state. It also is supposed to +use the device's _PRW control method to learn which power resources need to be +enabled for the device to be able to generate wakeup signals. + +1.4. Wakeup Signaling +--------------------- + +Wakeup signals generated by PCI devices, either as native PCI PMEs, or as +a result of the execution of the _DSW (or _PSW) ACPI control method before +putting the device into a low-power state, have to be caught and handled as +appropriate. If they are sent while the system is in the working state +(ACPI S0), they should be translated into interrupts so that the kernel can +put the devices generating them into the full-power state and take care of the +events that triggered them. In turn, if they are sent while the system is +sleeping, they should cause the system's core logic to trigger wakeup. + +On ACPI-based systems wakeup signals sent by conventional PCI devices are +converted into ACPI General-Purpose Events (GPEs) which are hardware signals +from the system core logic generated in response to various events that need to +be acted upon. Every GPE is associated with one or more sources of potentially +interesting events. In particular, a GPE may be associated with a PCI device +capable of signaling wakeup. The information on the connections between GPEs +and event sources is recorded in the system's ACPI BIOS from where it can be +read by the kernel. + +If a PCI device known to the system's ACPI BIOS signals wakeup, the GPE +associated with it (if there is one) is triggered. The GPEs associated with PCI +bridges may also be triggered in response to a wakeup signal from one of the +devices below the bridge (this also is the case for root bridges) and, for +example, native PCI PMEs from devices unknown to the system's ACPI BIOS may be +handled this way. + +A GPE may be triggered when the system is sleeping (i.e. when it is in one of +the ACPI S1-S4 states), in which case system wakeup is started by its core logic +(the device that was the source of the signal causing the system wakeup to occur +may be identified later). The GPEs used in such situations are referred to as +wakeup GPEs. + +Usually, however, GPEs are also triggered when the system is in the working +state (ACPI S0) and in that case the system's core logic generates a System +Control Interrupt (SCI) to notify the kernel of the event. Then, the SCI +handler identifies the GPE that caused the interrupt to be generated which, +in turn, allows the kernel to identify the source of the event (that may be +a PCI device signaling wakeup). The GPEs used for notifying the kernel of +events occurring while the system is in the working state are referred to as +runtime GPEs. + +Unfortunately, there is no standard way of handling wakeup signals sent by +conventional PCI devices on systems that are not ACPI-based, but there is one +for PCI Express devices. Namely, the PCI Express Base Specification introduced +a native mechanism for converting native PCI PMEs into interrupts generated by +root ports. For conventional PCI devices native PMEs are out-of-band, so they +are routed separately and they need not pass through bridges (in principle they +may be routed directly to the system's core logic), but for PCI Express devices +they are in-band messages that have to pass through the PCI Express hierarchy, +including the root port on the path from the device to the Root Complex. Thus +it was possible to introduce a mechanism by which a root port generates an +interrupt whenever it receives a PME message from one of the devices below it. +The PCI Express Requester ID of the device that sent the PME message is then +recorded in one of the root port's configuration registers from where it may be +read by the interrupt handler allowing the device to be identified. [PME +messages sent by PCI Express endpoints integrated with the Root Complex don't +pass through root ports, but instead they cause a Root Complex Event Collector +(if there is one) to generate interrupts.] + +In principle the native PCI Express PME signaling may also be used on ACPI-based +systems along with the GPEs, but to use it the kernel has to ask the system's +ACPI BIOS to release control of root port configuration registers. The ACPI +BIOS, however, is not required to allow the kernel to control these registers +and if it doesn't do that, the kernel must not modify their contents. Of course +the native PCI Express PME signaling cannot be used by the kernel in that case. + + +2. PCI Subsystem and Device Power Management +============================================ + +2.1. Device Power Management Callbacks +-------------------------------------- + +The PCI Subsystem participates in the power management of PCI devices in a +number of ways. First of all, it provides an intermediate code layer between +the device power management core (PM core) and PCI device drivers. +Specifically, the pm field of the PCI subsystem's struct bus_type object, +pci_bus_type, points to a struct dev_pm_ops object, pci_dev_pm_ops, containing +pointers to several device power management callbacks:: + + const struct dev_pm_ops pci_dev_pm_ops = { + .prepare = pci_pm_prepare, + .complete = pci_pm_complete, + .suspend = pci_pm_suspend, + .resume = pci_pm_resume, + .freeze = pci_pm_freeze, + .thaw = pci_pm_thaw, + .poweroff = pci_pm_poweroff, + .restore = pci_pm_restore, + .suspend_noirq = pci_pm_suspend_noirq, + .resume_noirq = pci_pm_resume_noirq, + .freeze_noirq = pci_pm_freeze_noirq, + .thaw_noirq = pci_pm_thaw_noirq, + .poweroff_noirq = pci_pm_poweroff_noirq, + .restore_noirq = pci_pm_restore_noirq, + .runtime_suspend = pci_pm_runtime_suspend, + .runtime_resume = pci_pm_runtime_resume, + .runtime_idle = pci_pm_runtime_idle, + }; + +These callbacks are executed by the PM core in various situations related to +device power management and they, in turn, execute power management callbacks +provided by PCI device drivers. They also perform power management operations +involving some standard configuration registers of PCI devices that device +drivers need not know or care about. + +The structure representing a PCI device, struct pci_dev, contains several fields +that these callbacks operate on:: + + struct pci_dev { + ... + pci_power_t current_state; /* Current operating state. */ + int pm_cap; /* PM capability offset in the + configuration space */ + unsigned int pme_support:5; /* Bitmask of states from which PME# + can be generated */ + unsigned int pme_interrupt:1;/* Is native PCIe PME signaling used? */ + unsigned int d1_support:1; /* Low power state D1 is supported */ + unsigned int d2_support:1; /* Low power state D2 is supported */ + unsigned int no_d1d2:1; /* D1 and D2 are forbidden */ + unsigned int wakeup_prepared:1; /* Device prepared for wake up */ + unsigned int d3_delay; /* D3->D0 transition time in ms */ + ... + }; + +They also indirectly use some fields of the struct device that is embedded in +struct pci_dev. + +2.2. Device Initialization +-------------------------- + +The PCI subsystem's first task related to device power management is to +prepare the device for power management and initialize the fields of struct +pci_dev used for this purpose. This happens in two functions defined in +drivers/pci/pci.c, pci_pm_init() and platform_pci_wakeup_init(). + +The first of these functions checks if the device supports native PCI PM +and if that's the case the offset of its power management capability structure +in the configuration space is stored in the pm_cap field of the device's struct +pci_dev object. Next, the function checks which PCI low-power states are +supported by the device and from which low-power states the device can generate +native PCI PMEs. The power management fields of the device's struct pci_dev and +the struct device embedded in it are updated accordingly and the generation of +PMEs by the device is disabled. + +The second function checks if the device can be prepared to signal wakeup with +the help of the platform firmware, such as the ACPI BIOS. If that is the case, +the function updates the wakeup fields in struct device embedded in the +device's struct pci_dev and uses the firmware-provided method to prevent the +device from signaling wakeup. + +At this point the device is ready for power management. For driverless devices, +however, this functionality is limited to a few basic operations carried out +during system-wide transitions to a sleep state and back to the working state. + +2.3. Runtime Device Power Management +------------------------------------ + +The PCI subsystem plays a vital role in the runtime power management of PCI +devices. For this purpose it uses the general runtime power management +(runtime PM) framework described in Documentation/power/runtime_pm.rst. +Namely, it provides subsystem-level callbacks:: + + pci_pm_runtime_suspend() + pci_pm_runtime_resume() + pci_pm_runtime_idle() + +that are executed by the core runtime PM routines. It also implements the +entire mechanics necessary for handling runtime wakeup signals from PCI devices +in low-power states, which at the time of this writing works for both the native +PCI Express PME signaling and the ACPI GPE-based wakeup signaling described in +Section 1. + +First, a PCI device is put into a low-power state, or suspended, with the help +of pm_schedule_suspend() or pm_runtime_suspend() which for PCI devices call +pci_pm_runtime_suspend() to do the actual job. For this to work, the device's +driver has to provide a pm->runtime_suspend() callback (see below), which is +run by pci_pm_runtime_suspend() as the first action. If the driver's callback +returns successfully, the device's standard configuration registers are saved, +the device is prepared to generate wakeup signals and, finally, it is put into +the target low-power state. + +The low-power state to put the device into is the lowest-power (highest number) +state from which it can signal wakeup. The exact method of signaling wakeup is +system-dependent and is determined by the PCI subsystem on the basis of the +reported capabilities of the device and the platform firmware. To prepare the +device for signaling wakeup and put it into the selected low-power state, the +PCI subsystem can use the platform firmware as well as the device's native PCI +PM capabilities, if supported. + +It is expected that the device driver's pm->runtime_suspend() callback will +not attempt to prepare the device for signaling wakeup or to put it into a +low-power state. The driver ought to leave these tasks to the PCI subsystem +that has all of the information necessary to perform them. + +A suspended device is brought back into the "active" state, or resumed, +with the help of pm_request_resume() or pm_runtime_resume() which both call +pci_pm_runtime_resume() for PCI devices. Again, this only works if the device's +driver provides a pm->runtime_resume() callback (see below). However, before +the driver's callback is executed, pci_pm_runtime_resume() brings the device +back into the full-power state, prevents it from signaling wakeup while in that +state and restores its standard configuration registers. Thus the driver's +callback need not worry about the PCI-specific aspects of the device resume. + +Note that generally pci_pm_runtime_resume() may be called in two different +situations. First, it may be called at the request of the device's driver, for +example if there are some data for it to process. Second, it may be called +as a result of a wakeup signal from the device itself (this sometimes is +referred to as "remote wakeup"). Of course, for this purpose the wakeup signal +is handled in one of the ways described in Section 1 and finally converted into +a notification for the PCI subsystem after the source device has been +identified. + +The pci_pm_runtime_idle() function, called for PCI devices by pm_runtime_idle() +and pm_request_idle(), executes the device driver's pm->runtime_idle() +callback, if defined, and if that callback doesn't return error code (or is not +present at all), suspends the device with the help of pm_runtime_suspend(). +Sometimes pci_pm_runtime_idle() is called automatically by the PM core (for +example, it is called right after the device has just been resumed), in which +cases it is expected to suspend the device if that makes sense. Usually, +however, the PCI subsystem doesn't really know if the device really can be +suspended, so it lets the device's driver decide by running its +pm->runtime_idle() callback. + +2.4. System-Wide Power Transitions +---------------------------------- +There are a few different types of system-wide power transitions, described in +Documentation/driver-api/pm/devices.rst. Each of them requires devices to be handled +in a specific way and the PM core executes subsystem-level power management +callbacks for this purpose. They are executed in phases such that each phase +involves executing the same subsystem-level callback for every device belonging +to the given subsystem before the next phase begins. These phases always run +after tasks have been frozen. + +2.4.1. System Suspend +^^^^^^^^^^^^^^^^^^^^^ + +When the system is going into a sleep state in which the contents of memory will +be preserved, such as one of the ACPI sleep states S1-S3, the phases are: + + prepare, suspend, suspend_noirq. + +The following PCI bus type's callbacks, respectively, are used in these phases:: + + pci_pm_prepare() + pci_pm_suspend() + pci_pm_suspend_noirq() + +The pci_pm_prepare() routine first puts the device into the "fully functional" +state with the help of pm_runtime_resume(). Then, it executes the device +driver's pm->prepare() callback if defined (i.e. if the driver's struct +dev_pm_ops object is present and the prepare pointer in that object is valid). + +The pci_pm_suspend() routine first checks if the device's driver implements +legacy PCI suspend routines (see Section 3), in which case the driver's legacy +suspend callback is executed, if present, and its result is returned. Next, if +the device's driver doesn't provide a struct dev_pm_ops object (containing +pointers to the driver's callbacks), pci_pm_default_suspend() is called, which +simply turns off the device's bus master capability and runs +pcibios_disable_device() to disable it, unless the device is a bridge (PCI +bridges are ignored by this routine). Next, the device driver's pm->suspend() +callback is executed, if defined, and its result is returned if it fails. +Finally, pci_fixup_device() is called to apply hardware suspend quirks related +to the device if necessary. + +Note that the suspend phase is carried out asynchronously for PCI devices, so +the pci_pm_suspend() callback may be executed in parallel for any pair of PCI +devices that don't depend on each other in a known way (i.e. none of the paths +in the device tree from the root bridge to a leaf device contains both of them). + +The pci_pm_suspend_noirq() routine is executed after suspend_device_irqs() has +been called, which means that the device driver's interrupt handler won't be +invoked while this routine is running. It first checks if the device's driver +implements legacy PCI suspends routines (Section 3), in which case the legacy +late suspend routine is called and its result is returned (the standard +configuration registers of the device are saved if the driver's callback hasn't +done that). Second, if the device driver's struct dev_pm_ops object is not +present, the device's standard configuration registers are saved and the routine +returns success. Otherwise the device driver's pm->suspend_noirq() callback is +executed, if present, and its result is returned if it fails. Next, if the +device's standard configuration registers haven't been saved yet (one of the +device driver's callbacks executed before might do that), pci_pm_suspend_noirq() +saves them, prepares the device to signal wakeup (if necessary) and puts it into +a low-power state. + +The low-power state to put the device into is the lowest-power (highest number) +state from which it can signal wakeup while the system is in the target sleep +state. Just like in the runtime PM case described above, the mechanism of +signaling wakeup is system-dependent and determined by the PCI subsystem, which +is also responsible for preparing the device to signal wakeup from the system's +target sleep state as appropriate. + +PCI device drivers (that don't implement legacy power management callbacks) are +generally not expected to prepare devices for signaling wakeup or to put them +into low-power states. However, if one of the driver's suspend callbacks +(pm->suspend() or pm->suspend_noirq()) saves the device's standard configuration +registers, pci_pm_suspend_noirq() will assume that the device has been prepared +to signal wakeup and put into a low-power state by the driver (the driver is +then assumed to have used the helper functions provided by the PCI subsystem for +this purpose). PCI device drivers are not encouraged to do that, but in some +rare cases doing that in the driver may be the optimum approach. + +2.4.2. System Resume +^^^^^^^^^^^^^^^^^^^^ + +When the system is undergoing a transition from a sleep state in which the +contents of memory have been preserved, such as one of the ACPI sleep states +S1-S3, into the working state (ACPI S0), the phases are: + + resume_noirq, resume, complete. + +The following PCI bus type's callbacks, respectively, are executed in these +phases:: + + pci_pm_resume_noirq() + pci_pm_resume() + pci_pm_complete() + +The pci_pm_resume_noirq() routine first puts the device into the full-power +state, restores its standard configuration registers and applies early resume +hardware quirks related to the device, if necessary. This is done +unconditionally, regardless of whether or not the device's driver implements +legacy PCI power management callbacks (this way all PCI devices are in the +full-power state and their standard configuration registers have been restored +when their interrupt handlers are invoked for the first time during resume, +which allows the kernel to avoid problems with the handling of shared interrupts +by drivers whose devices are still suspended). If legacy PCI power management +callbacks (see Section 3) are implemented by the device's driver, the legacy +early resume callback is executed and its result is returned. Otherwise, the +device driver's pm->resume_noirq() callback is executed, if defined, and its +result is returned. + +The pci_pm_resume() routine first checks if the device's standard configuration +registers have been restored and restores them if that's not the case (this +only is necessary in the error path during a failing suspend). Next, resume +hardware quirks related to the device are applied, if necessary, and if the +device's driver implements legacy PCI power management callbacks (see +Section 3), the driver's legacy resume callback is executed and its result is +returned. Otherwise, the device's wakeup signaling mechanisms are blocked and +its driver's pm->resume() callback is executed, if defined (the callback's +result is then returned). + +The resume phase is carried out asynchronously for PCI devices, like the +suspend phase described above, which means that if two PCI devices don't depend +on each other in a known way, the pci_pm_resume() routine may be executed for +the both of them in parallel. + +The pci_pm_complete() routine only executes the device driver's pm->complete() +callback, if defined. + +2.4.3. System Hibernation +^^^^^^^^^^^^^^^^^^^^^^^^^ + +System hibernation is more complicated than system suspend, because it requires +a system image to be created and written into a persistent storage medium. The +image is created atomically and all devices are quiesced, or frozen, before that +happens. + +The freezing of devices is carried out after enough memory has been freed (at +the time of this writing the image creation requires at least 50% of system RAM +to be free) in the following three phases: + + prepare, freeze, freeze_noirq + +that correspond to the PCI bus type's callbacks:: + + pci_pm_prepare() + pci_pm_freeze() + pci_pm_freeze_noirq() + +This means that the prepare phase is exactly the same as for system suspend. +The other two phases, however, are different. + +The pci_pm_freeze() routine is quite similar to pci_pm_suspend(), but it runs +the device driver's pm->freeze() callback, if defined, instead of pm->suspend(), +and it doesn't apply the suspend-related hardware quirks. It is executed +asynchronously for different PCI devices that don't depend on each other in a +known way. + +The pci_pm_freeze_noirq() routine, in turn, is similar to +pci_pm_suspend_noirq(), but it calls the device driver's pm->freeze_noirq() +routine instead of pm->suspend_noirq(). It also doesn't attempt to prepare the +device for signaling wakeup and put it into a low-power state. Still, it saves +the device's standard configuration registers if they haven't been saved by one +of the driver's callbacks. + +Once the image has been created, it has to be saved. However, at this point all +devices are frozen and they cannot handle I/O, while their ability to handle +I/O is obviously necessary for the image saving. Thus they have to be brought +back to the fully functional state and this is done in the following phases: + + thaw_noirq, thaw, complete + +using the following PCI bus type's callbacks:: + + pci_pm_thaw_noirq() + pci_pm_thaw() + pci_pm_complete() + +respectively. + +The first of them, pci_pm_thaw_noirq(), is analogous to pci_pm_resume_noirq(), +but it doesn't put the device into the full power state and doesn't attempt to +restore its standard configuration registers. It also executes the device +driver's pm->thaw_noirq() callback, if defined, instead of pm->resume_noirq(). + +The pci_pm_thaw() routine is similar to pci_pm_resume(), but it runs the device +driver's pm->thaw() callback instead of pm->resume(). It is executed +asynchronously for different PCI devices that don't depend on each other in a +known way. + +The complete phase it the same as for system resume. + +After saving the image, devices need to be powered down before the system can +enter the target sleep state (ACPI S4 for ACPI-based systems). This is done in +three phases: + + prepare, poweroff, poweroff_noirq + +where the prepare phase is exactly the same as for system suspend. The other +two phases are analogous to the suspend and suspend_noirq phases, respectively. +The PCI subsystem-level callbacks they correspond to:: + + pci_pm_poweroff() + pci_pm_poweroff_noirq() + +work in analogy with pci_pm_suspend() and pci_pm_poweroff_noirq(), respectively, +although they don't attempt to save the device's standard configuration +registers. + +2.4.4. System Restore +^^^^^^^^^^^^^^^^^^^^^ + +System restore requires a hibernation image to be loaded into memory and the +pre-hibernation memory contents to be restored before the pre-hibernation system +activity can be resumed. + +As described in Documentation/driver-api/pm/devices.rst, the hibernation image is loaded +into memory by a fresh instance of the kernel, called the boot kernel, which in +turn is loaded and run by a boot loader in the usual way. After the boot kernel +has loaded the image, it needs to replace its own code and data with the code +and data of the "hibernated" kernel stored within the image, called the image +kernel. For this purpose all devices are frozen just like before creating +the image during hibernation, in the + + prepare, freeze, freeze_noirq + +phases described above. However, the devices affected by these phases are only +those having drivers in the boot kernel; other devices will still be in whatever +state the boot loader left them. + +Should the restoration of the pre-hibernation memory contents fail, the boot +kernel would go through the "thawing" procedure described above, using the +thaw_noirq, thaw, and complete phases (that will only affect the devices having +drivers in the boot kernel), and then continue running normally. + +If the pre-hibernation memory contents are restored successfully, which is the +usual situation, control is passed to the image kernel, which then becomes +responsible for bringing the system back to the working state. To achieve this, +it must restore the devices' pre-hibernation functionality, which is done much +like waking up from the memory sleep state, although it involves different +phases: + + restore_noirq, restore, complete + +The first two of these are analogous to the resume_noirq and resume phases +described above, respectively, and correspond to the following PCI subsystem +callbacks:: + + pci_pm_restore_noirq() + pci_pm_restore() + +These callbacks work in analogy with pci_pm_resume_noirq() and pci_pm_resume(), +respectively, but they execute the device driver's pm->restore_noirq() and +pm->restore() callbacks, if available. + +The complete phase is carried out in exactly the same way as during system +resume. + + +3. PCI Device Drivers and Power Management +========================================== + +3.1. Power Management Callbacks +------------------------------- + +PCI device drivers participate in power management by providing callbacks to be +executed by the PCI subsystem's power management routines described above and by +controlling the runtime power management of their devices. + +At the time of this writing there are two ways to define power management +callbacks for a PCI device driver, the recommended one, based on using a +dev_pm_ops structure described in Documentation/driver-api/pm/devices.rst, and the +"legacy" one, in which the .suspend(), .suspend_late(), .resume_early(), and +.resume() callbacks from struct pci_driver are used. The legacy approach, +however, doesn't allow one to define runtime power management callbacks and is +not really suitable for any new drivers. Therefore it is not covered by this +document (refer to the source code to learn more about it). + +It is recommended that all PCI device drivers define a struct dev_pm_ops object +containing pointers to power management (PM) callbacks that will be executed by +the PCI subsystem's PM routines in various circumstances. A pointer to the +driver's struct dev_pm_ops object has to be assigned to the driver.pm field in +its struct pci_driver object. Once that has happened, the "legacy" PM callbacks +in struct pci_driver are ignored (even if they are not NULL). + +The PM callbacks in struct dev_pm_ops are not mandatory and if they are not +defined (i.e. the respective fields of struct dev_pm_ops are unset) the PCI +subsystem will handle the device in a simplified default manner. If they are +defined, though, they are expected to behave as described in the following +subsections. + +3.1.1. prepare() +^^^^^^^^^^^^^^^^ + +The prepare() callback is executed during system suspend, during hibernation +(when a hibernation image is about to be created), during power-off after +saving a hibernation image and during system restore, when a hibernation image +has just been loaded into memory. + +This callback is only necessary if the driver's device has children that in +general may be registered at any time. In that case the role of the prepare() +callback is to prevent new children of the device from being registered until +one of the resume_noirq(), thaw_noirq(), or restore_noirq() callbacks is run. + +In addition to that the prepare() callback may carry out some operations +preparing the device to be suspended, although it should not allocate memory +(if additional memory is required to suspend the device, it has to be +preallocated earlier, for example in a suspend/hibernate notifier as described +in Documentation/driver-api/pm/notifiers.rst). + +3.1.2. suspend() +^^^^^^^^^^^^^^^^ + +The suspend() callback is only executed during system suspend, after prepare() +callbacks have been executed for all devices in the system. + +This callback is expected to quiesce the device and prepare it to be put into a +low-power state by the PCI subsystem. It is not required (in fact it even is +not recommended) that a PCI driver's suspend() callback save the standard +configuration registers of the device, prepare it for waking up the system, or +put it into a low-power state. All of these operations can very well be taken +care of by the PCI subsystem, without the driver's participation. + +However, in some rare case it is convenient to carry out these operations in +a PCI driver. Then, pci_save_state(), pci_prepare_to_sleep(), and +pci_set_power_state() should be used to save the device's standard configuration +registers, to prepare it for system wakeup (if necessary), and to put it into a +low-power state, respectively. Moreover, if the driver calls pci_save_state(), +the PCI subsystem will not execute either pci_prepare_to_sleep(), or +pci_set_power_state() for its device, so the driver is then responsible for +handling the device as appropriate. + +While the suspend() callback is being executed, the driver's interrupt handler +can be invoked to handle an interrupt from the device, so all suspend-related +operations relying on the driver's ability to handle interrupts should be +carried out in this callback. + +3.1.3. suspend_noirq() +^^^^^^^^^^^^^^^^^^^^^^ + +The suspend_noirq() callback is only executed during system suspend, after +suspend() callbacks have been executed for all devices in the system and +after device interrupts have been disabled by the PM core. + +The difference between suspend_noirq() and suspend() is that the driver's +interrupt handler will not be invoked while suspend_noirq() is running. Thus +suspend_noirq() can carry out operations that would cause race conditions to +arise if they were performed in suspend(). + +3.1.4. freeze() +^^^^^^^^^^^^^^^ + +The freeze() callback is hibernation-specific and is executed in two situations, +during hibernation, after prepare() callbacks have been executed for all devices +in preparation for the creation of a system image, and during restore, +after a system image has been loaded into memory from persistent storage and the +prepare() callbacks have been executed for all devices. + +The role of this callback is analogous to the role of the suspend() callback +described above. In fact, they only need to be different in the rare cases when +the driver takes the responsibility for putting the device into a low-power +state. + +In that cases the freeze() callback should not prepare the device system wakeup +or put it into a low-power state. Still, either it or freeze_noirq() should +save the device's standard configuration registers using pci_save_state(). + +3.1.5. freeze_noirq() +^^^^^^^^^^^^^^^^^^^^^ + +The freeze_noirq() callback is hibernation-specific. It is executed during +hibernation, after prepare() and freeze() callbacks have been executed for all +devices in preparation for the creation of a system image, and during restore, +after a system image has been loaded into memory and after prepare() and +freeze() callbacks have been executed for all devices. It is always executed +after device interrupts have been disabled by the PM core. + +The role of this callback is analogous to the role of the suspend_noirq() +callback described above and it very rarely is necessary to define +freeze_noirq(). + +The difference between freeze_noirq() and freeze() is analogous to the +difference between suspend_noirq() and suspend(). + +3.1.6. poweroff() +^^^^^^^^^^^^^^^^^ + +The poweroff() callback is hibernation-specific. It is executed when the system +is about to be powered off after saving a hibernation image to a persistent +storage. prepare() callbacks are executed for all devices before poweroff() is +called. + +The role of this callback is analogous to the role of the suspend() and freeze() +callbacks described above, although it does not need to save the contents of +the device's registers. In particular, if the driver wants to put the device +into a low-power state itself instead of allowing the PCI subsystem to do that, +the poweroff() callback should use pci_prepare_to_sleep() and +pci_set_power_state() to prepare the device for system wakeup and to put it +into a low-power state, respectively, but it need not save the device's standard +configuration registers. + +3.1.7. poweroff_noirq() +^^^^^^^^^^^^^^^^^^^^^^^ + +The poweroff_noirq() callback is hibernation-specific. It is executed after +poweroff() callbacks have been executed for all devices in the system. + +The role of this callback is analogous to the role of the suspend_noirq() and +freeze_noirq() callbacks described above, but it does not need to save the +contents of the device's registers. + +The difference between poweroff_noirq() and poweroff() is analogous to the +difference between suspend_noirq() and suspend(). + +3.1.8. resume_noirq() +^^^^^^^^^^^^^^^^^^^^^ + +The resume_noirq() callback is only executed during system resume, after the +PM core has enabled the non-boot CPUs. The driver's interrupt handler will not +be invoked while resume_noirq() is running, so this callback can carry out +operations that might race with the interrupt handler. + +Since the PCI subsystem unconditionally puts all devices into the full power +state in the resume_noirq phase of system resume and restores their standard +configuration registers, resume_noirq() is usually not necessary. In general +it should only be used for performing operations that would lead to race +conditions if carried out by resume(). + +3.1.9. resume() +^^^^^^^^^^^^^^^ + +The resume() callback is only executed during system resume, after +resume_noirq() callbacks have been executed for all devices in the system and +device interrupts have been enabled by the PM core. + +This callback is responsible for restoring the pre-suspend configuration of the +device and bringing it back to the fully functional state. The device should be +able to process I/O in a usual way after resume() has returned. + +3.1.10. thaw_noirq() +^^^^^^^^^^^^^^^^^^^^ + +The thaw_noirq() callback is hibernation-specific. It is executed after a +system image has been created and the non-boot CPUs have been enabled by the PM +core, in the thaw_noirq phase of hibernation. It also may be executed if the +loading of a hibernation image fails during system restore (it is then executed +after enabling the non-boot CPUs). The driver's interrupt handler will not be +invoked while thaw_noirq() is running. + +The role of this callback is analogous to the role of resume_noirq(). The +difference between these two callbacks is that thaw_noirq() is executed after +freeze() and freeze_noirq(), so in general it does not need to modify the +contents of the device's registers. + +3.1.11. thaw() +^^^^^^^^^^^^^^ + +The thaw() callback is hibernation-specific. It is executed after thaw_noirq() +callbacks have been executed for all devices in the system and after device +interrupts have been enabled by the PM core. + +This callback is responsible for restoring the pre-freeze configuration of +the device, so that it will work in a usual way after thaw() has returned. + +3.1.12. restore_noirq() +^^^^^^^^^^^^^^^^^^^^^^^ + +The restore_noirq() callback is hibernation-specific. It is executed in the +restore_noirq phase of hibernation, when the boot kernel has passed control to +the image kernel and the non-boot CPUs have been enabled by the image kernel's +PM core. + +This callback is analogous to resume_noirq() with the exception that it cannot +make any assumption on the previous state of the device, even if the BIOS (or +generally the platform firmware) is known to preserve that state over a +suspend-resume cycle. + +For the vast majority of PCI device drivers there is no difference between +resume_noirq() and restore_noirq(). + +3.1.13. restore() +^^^^^^^^^^^^^^^^^ + +The restore() callback is hibernation-specific. It is executed after +restore_noirq() callbacks have been executed for all devices in the system and +after the PM core has enabled device drivers' interrupt handlers to be invoked. + +This callback is analogous to resume(), just like restore_noirq() is analogous +to resume_noirq(). Consequently, the difference between restore_noirq() and +restore() is analogous to the difference between resume_noirq() and resume(). + +For the vast majority of PCI device drivers there is no difference between +resume() and restore(). + +3.1.14. complete() +^^^^^^^^^^^^^^^^^^ + +The complete() callback is executed in the following situations: + + - during system resume, after resume() callbacks have been executed for all + devices, + - during hibernation, before saving the system image, after thaw() callbacks + have been executed for all devices, + - during system restore, when the system is going back to its pre-hibernation + state, after restore() callbacks have been executed for all devices. + +It also may be executed if the loading of a hibernation image into memory fails +(in that case it is run after thaw() callbacks have been executed for all +devices that have drivers in the boot kernel). + +This callback is entirely optional, although it may be necessary if the +prepare() callback performs operations that need to be reversed. + +3.1.15. runtime_suspend() +^^^^^^^^^^^^^^^^^^^^^^^^^ + +The runtime_suspend() callback is specific to device runtime power management +(runtime PM). It is executed by the PM core's runtime PM framework when the +device is about to be suspended (i.e. quiesced and put into a low-power state) +at run time. + +This callback is responsible for freezing the device and preparing it to be +put into a low-power state, but it must allow the PCI subsystem to perform all +of the PCI-specific actions necessary for suspending the device. + +3.1.16. runtime_resume() +^^^^^^^^^^^^^^^^^^^^^^^^ + +The runtime_resume() callback is specific to device runtime PM. It is executed +by the PM core's runtime PM framework when the device is about to be resumed +(i.e. put into the full-power state and programmed to process I/O normally) at +run time. + +This callback is responsible for restoring the normal functionality of the +device after it has been put into the full-power state by the PCI subsystem. +The device is expected to be able to process I/O in the usual way after +runtime_resume() has returned. + +3.1.17. runtime_idle() +^^^^^^^^^^^^^^^^^^^^^^ + +The runtime_idle() callback is specific to device runtime PM. It is executed +by the PM core's runtime PM framework whenever it may be desirable to suspend +the device according to the PM core's information. In particular, it is +automatically executed right after runtime_resume() has returned in case the +resume of the device has happened as a result of a spurious event. + +This callback is optional, but if it is not implemented or if it returns 0, the +PCI subsystem will call pm_runtime_suspend() for the device, which in turn will +cause the driver's runtime_suspend() callback to be executed. + +3.1.18. Pointing Multiple Callback Pointers to One Routine +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Although in principle each of the callbacks described in the previous +subsections can be defined as a separate function, it often is convenient to +point two or more members of struct dev_pm_ops to the same routine. There are +a few convenience macros that can be used for this purpose. + +The SIMPLE_DEV_PM_OPS macro declares a struct dev_pm_ops object with one +suspend routine pointed to by the .suspend(), .freeze(), and .poweroff() +members and one resume routine pointed to by the .resume(), .thaw(), and +.restore() members. The other function pointers in this struct dev_pm_ops are +unset. + +The UNIVERSAL_DEV_PM_OPS macro is similar to SIMPLE_DEV_PM_OPS, but it +additionally sets the .runtime_resume() pointer to the same value as +.resume() (and .thaw(), and .restore()) and the .runtime_suspend() pointer to +the same value as .suspend() (and .freeze() and .poweroff()). + +The SET_SYSTEM_SLEEP_PM_OPS can be used inside of a declaration of struct +dev_pm_ops to indicate that one suspend routine is to be pointed to by the +.suspend(), .freeze(), and .poweroff() members and one resume routine is to +be pointed to by the .resume(), .thaw(), and .restore() members. + +3.1.19. Driver Flags for Power Management +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The PM core allows device drivers to set flags that influence the handling of +power management for the devices by the core itself and by middle layer code +including the PCI bus type. The flags should be set once at the driver probe +time with the help of the dev_pm_set_driver_flags() function and they should not +be updated directly afterwards. + +The DPM_FLAG_NEVER_SKIP flag prevents the PM core from using the direct-complete +mechanism allowing device suspend/resume callbacks to be skipped if the device +is in runtime suspend when the system suspend starts. That also affects all of +the ancestors of the device, so this flag should only be used if absolutely +necessary. + +The DPM_FLAG_SMART_PREPARE flag instructs the PCI bus type to only return a +positive value from pci_pm_prepare() if the ->prepare callback provided by the +driver of the device returns a positive value. That allows the driver to opt +out from using the direct-complete mechanism dynamically. + +The DPM_FLAG_SMART_SUSPEND flag tells the PCI bus type that from the driver's +perspective the device can be safely left in runtime suspend during system +suspend. That causes pci_pm_suspend(), pci_pm_freeze() and pci_pm_poweroff() +to skip resuming the device from runtime suspend unless there are PCI-specific +reasons for doing that. Also, it causes pci_pm_suspend_late/noirq(), +pci_pm_freeze_late/noirq() and pci_pm_poweroff_late/noirq() to return early +if the device remains in runtime suspend in the beginning of the "late" phase +of the system-wide transition under way. Moreover, if the device is in +runtime suspend in pci_pm_resume_noirq() or pci_pm_restore_noirq(), its runtime +power management status will be changed to "active" (as it is going to be put +into D0 going forward), but if it is in runtime suspend in pci_pm_thaw_noirq(), +the function will set the power.direct_complete flag for it (to make the PM core +skip the subsequent "thaw" callbacks for it) and return. + +Setting the DPM_FLAG_LEAVE_SUSPENDED flag means that the driver prefers the +device to be left in suspend after system-wide transitions to the working state. +This flag is checked by the PM core, but the PCI bus type informs the PM core +which devices may be left in suspend from its perspective (that happens during +the "noirq" phase of system-wide suspend and analogous transitions) and next it +uses the dev_pm_may_skip_resume() helper to decide whether or not to return from +pci_pm_resume_noirq() early, as the PM core will skip the remaining resume +callbacks for the device during the transition under way and will set its +runtime PM status to "suspended" if dev_pm_may_skip_resume() returns "true" for +it. + +3.2. Device Runtime Power Management +------------------------------------ + +In addition to providing device power management callbacks PCI device drivers +are responsible for controlling the runtime power management (runtime PM) of +their devices. + +The PCI device runtime PM is optional, but it is recommended that PCI device +drivers implement it at least in the cases where there is a reliable way of +verifying that the device is not used (like when the network cable is detached +from an Ethernet adapter or there are no devices attached to a USB controller). + +To support the PCI runtime PM the driver first needs to implement the +runtime_suspend() and runtime_resume() callbacks. It also may need to implement +the runtime_idle() callback to prevent the device from being suspended again +every time right after the runtime_resume() callback has returned +(alternatively, the runtime_suspend() callback will have to check if the +device should really be suspended and return -EAGAIN if that is not the case). + +The runtime PM of PCI devices is enabled by default by the PCI core. PCI +device drivers do not need to enable it and should not attempt to do so. +However, it is blocked by pci_pm_init() that runs the pm_runtime_forbid() +helper function. In addition to that, the runtime PM usage counter of +each PCI device is incremented by local_pci_probe() before executing the +probe callback provided by the device's driver. + +If a PCI driver implements the runtime PM callbacks and intends to use the +runtime PM framework provided by the PM core and the PCI subsystem, it needs +to decrement the device's runtime PM usage counter in its probe callback +function. If it doesn't do that, the counter will always be different from +zero for the device and it will never be runtime-suspended. The simplest +way to do that is by calling pm_runtime_put_noidle(), but if the driver +wants to schedule an autosuspend right away, for example, it may call +pm_runtime_put_autosuspend() instead for this purpose. Generally, it +just needs to call a function that decrements the devices usage counter +from its probe routine to make runtime PM work for the device. + +It is important to remember that the driver's runtime_suspend() callback +may be executed right after the usage counter has been decremented, because +user space may already have caused the pm_runtime_allow() helper function +unblocking the runtime PM of the device to run via sysfs, so the driver must +be prepared to cope with that. + +The driver itself should not call pm_runtime_allow(), though. Instead, it +should let user space or some platform-specific code do that (user space can +do it via sysfs as stated above), but it must be prepared to handle the +runtime PM of the device correctly as soon as pm_runtime_allow() is called +(which may happen at any time, even before the driver is loaded). + +When the driver's remove callback runs, it has to balance the decrementation +of the device's runtime PM usage counter at the probe time. For this reason, +if it has decremented the counter in its probe callback, it must run +pm_runtime_get_noresume() in its remove callback. [Since the core carries +out a runtime resume of the device and bumps up the device's usage counter +before running the driver's remove callback, the runtime PM of the device +is effectively disabled for the duration of the remove execution and all +runtime PM helper functions incrementing the device's usage counter are +then effectively equivalent to pm_runtime_get_noresume().] + +The runtime PM framework works by processing requests to suspend or resume +devices, or to check if they are idle (in which cases it is reasonable to +subsequently request that they be suspended). These requests are represented +by work items put into the power management workqueue, pm_wq. Although there +are a few situations in which power management requests are automatically +queued by the PM core (for example, after processing a request to resume a +device the PM core automatically queues a request to check if the device is +idle), device drivers are generally responsible for queuing power management +requests for their devices. For this purpose they should use the runtime PM +helper functions provided by the PM core, discussed in +Documentation/power/runtime_pm.rst. + +Devices can also be suspended and resumed synchronously, without placing a +request into pm_wq. In the majority of cases this also is done by their +drivers that use helper functions provided by the PM core for this purpose. + +For more information on the runtime PM of devices refer to +Documentation/power/runtime_pm.rst. + + +4.

Hardware and Platform Support for PCI Power Management -========================================================= - -1.1. Native and Platform-Based Power Management ------------------------------------------------ -In general, power management is a feature allowing one to save energy by putting -devices into states in which they draw less power (low-power states) at the -price of reduced functionality or performance. - -Usually, a device is put into a low-power state when it is underutilized or -completely inactive. However, when it is necessary to use the device once -again, it has to be put back into the "fully functional" state (full-power -state). This may happen when there are some data for the device to handle or -as a result of an external event requiring the device to be active, which may -be signaled by the device itself. - -PCI devices may be put into low-power states in two ways, by using the device -capabilities introduced by the PCI Bus Power Management Interface Specification, -or with the help of platform firmware, such as an ACPI BIOS. In the first -approach, that is referred to as the native PCI power management (native PCI PM) -in what follows, the device power state is changed as a result of writing a -specific value into one of its standard configuration registers. The second -approach requires the platform firmware to provide special methods that may be -used by the kernel to change the device's power state. - -Devices supporting the native PCI PM usually can generate wakeup signals called -Power Management Events (PMEs) to let the kernel know about external events -requiring the device to be active. After receiving a PME the kernel is supposed -to put the device that sent it into the full-power state. However, the PCI Bus -Power Management Interface Specification doesn't define any standard method of -delivering the PME from the device to the CPU and the operating system kernel. -It is assumed that the platform firmware will perform this task and therefore, -even though a PCI device is set up to generate PMEs, it also may be necessary to -prepare the platform firmware for notifying the CPU of the PMEs coming from the -device (e.g. by generating interrupts). - -In turn, if the methods provided by the platform firmware are used for changing -the power state of a device, usually the platform also provides a method for -preparing the device to generate wakeup signals. In that case, however, it -often also is necessary to prepare the device for generating PMEs using the -native PCI PM mechanism, because the method provided by the platform depends on -that. - -Thus in many situations both the native and the platform-based power management -mechanisms have to be used simultaneously to obtain the desired result. - -1.2. Native PCI Power Management --------------------------------- -The PCI Bus Power Management Interface Specification (PCI PM Spec) was -introduced between the PCI 2.1 and PCI 2.2 Specifications. It defined a -standard interface for performing various operations related to power -management. - -The implementation of the PCI PM Spec is optional for conventional PCI devices, -but it is mandatory for PCI Express devices. If a device supports the PCI PM -Spec, it has an 8 byte power management capability field in its PCI -configuration space. This field is used to describe and control the standard -features related to the native PCI power management. - -The PCI PM Spec defines 4 operating states for devices (D0-D3) and for buses -(B0-B3). The higher the number, the less power is drawn by the device or bus -in that state. However, the higher the number, the longer the latency for -the device or bus to return to the full-power state (D0 or B0, respectively). - -There are two variants of the D3 state defined by the specification. The first -one is D3hot, referred to as the software accessible D3, because devices can be -programmed to go into it. The second one, D3cold, is the state that PCI devices -are in when the supply voltage (Vcc) is removed from them. It is not possible -to program a PCI device to go into D3cold, although there may be a programmable -interface for putting the bus the device is on into a state in which Vcc is -removed from all devices on the bus. - -PCI bus power management, however, is not supported by the Linux kernel at the -time of this writing and therefore it is not covered by this document. - -Note that every PCI device can be in the full-power state (D0) or in D3cold, -regardless of whether or not it implements the PCI PM Spec. In addition to -that, if the PCI PM Spec is implemented by the device, it must support D3hot -as well as D0. The support for the D1 and D2 power states is optional. - -PCI devices supporting the PCI PM Spec can be programmed to go to any of the -supported low-power states (except for D3cold). While in D1-D3hot the -standard configuration registers of the device must be accessible to software -(i.e. the device is required to respond to PCI configuration accesses), although -its I/O and memory spaces are then disabled. This allows the device to be -programmatically put into D0. Thus the kernel can switch the device back and -forth between D0 and the supported low-power states (except for D3cold) and the -possible power state transitions the device can undergo are the following: - -+----------------------------+ -| Current State | New State | -+----------------------------+ -| D0 | D1, D2, D3 | -+----------------------------+ -| D1 | D2, D3 | -+----------------------------+ -| D2 | D3 | -+----------------------------+ -| D1, D2, D3 | D0 | -+----------------------------+ - -The transition from D3cold to D0 occurs when the supply voltage is provided to -the device (i.e. power is restored). In that case the device returns to D0 with -a full power-on reset sequence and the power-on defaults are restored to the -device by hardware just as at initial power up. - -PCI devices supporting the PCI PM Spec can be programmed to generate PMEs -while in a low-power state (D1-D3), but they are not required to be capable -of generating PMEs from all supported low-power states. In particular, the -capability of generating PMEs from D3cold is optional and depends on the -presence of additional voltage (3.3Vaux) allowing the device to remain -sufficiently active to generate a wakeup signal. - -1.3. ACPI Device Power Management ---------------------------------- -The platform firmware support for the power management of PCI devices is -system-specific. However, if the system in question is compliant with the -Advanced Configuration and Power Interface (ACPI) Specification, like the -majority of x86-based systems, it is supposed to implement device power -management interfaces defined by the ACPI standard. - -For this purpose the ACPI BIOS provides special functions called "control -methods" that may be executed by the kernel to perform specific tasks, such as -putting a device into a low-power state. These control methods are encoded -using special byte-code language called the ACPI Machine Language (AML) and -stored in the machine's BIOS. The kernel loads them from the BIOS and executes -them as needed using an AML interpreter that translates the AML byte code into -computations and memory or I/O space accesses. This way, in theory, a BIOS -writer can provide the kernel with a means to perform actions depending -on the system design in a system-specific fashion. - -ACPI control methods may be divided into global control methods, that are not -associated with any particular devices, and device control methods, that have -to be defined separately for each device supposed to be handled with the help of -the platform. This means, in particular, that ACPI device control methods can -only be used to handle devices that the BIOS writer knew about in advance. The -ACPI methods used for device power management fall into that category. - -The ACPI specification assumes that devices can be in one of four power states -labeled as D0, D1, D2, and D3 that roughly correspond to the native PCI PM -D0-D3 states (although the difference between D3hot and D3cold is not taken -into account by ACPI). Moreover, for each power state of a device there is a -set of power resources that have to be enabled for the device to be put into -that state. These power resources are controlled (i.e. enabled or disabled) -with the help of their own control methods, _ON and _OFF, that have to be -defined individually for each of them. - -To put a device into the ACPI power state Dx (where x is a number between 0 and -3 inclusive) the kernel is supposed to (1) enable the power resources required -by the device in this state using their _ON control methods and (2) execute the -_PSx control method defined for the device. In addition to that, if the device -is going to be put into a low-power state (D1-D3) and is supposed to generate -wakeup signals from that state, the _DSW (or _PSW, replaced with _DSW by ACPI -3.0) control method defined for it has to be executed before _PSx. Power -resources that are not required by the device in the target power state and are -not required any more by any other device should be disabled (by executing their -_OFF control methods). If the current power state of the device is D3, it can -only be put into D0 this way. - -However, quite often the power states of devices are changed during a -system-wide transition into a sleep state or back into the working state. ACPI -defines four system sleep states, S1, S2, S3, and S4, and denotes the system -working state as S0. In general, the target system sleep (or working) state -determines the highest power (lowest number) state the device can be put -into and the kernel is supposed to obtain this information by executing the -device's _SxD control method (where x is a number between 0 and 4 inclusive). -If the device is required to wake up the system from the target sleep state, the -lowest power (highest number) state it can be put into is also determined by the -target state of the system. The kernel is then supposed to use the device's -_SxW control method to obtain the number of that state. It also is supposed to -use the device's _PRW control method to learn which power resources need to be -enabled for the device to be able to generate wakeup signals. - -1.4. Wakeup Signaling ---------------------- -Wakeup signals generated by PCI devices, either as native PCI PMEs, or as -a result of the execution of the _DSW (or _PSW) ACPI control method before -putting the device into a low-power state, have to be caught and handled as -appropriate. If they are sent while the system is in the working state -(ACPI S0), they should be translated into interrupts so that the kernel can -put the devices generating them into the full-power state and take care of the -events that triggered them. In turn, if they are sent while the system is -sleeping, they should cause the system's core logic to trigger wakeup. - -On ACPI-based systems wakeup signals sent by conventional PCI devices are -converted into ACPI General-Purpose Events (GPEs) which are hardware signals -from the system core logic generated in response to various events that need to -be acted upon. Every GPE is associated with one or more sources of potentially -interesting events. In particular, a GPE may be associated with a PCI device -capable of signaling wakeup. The information on the connections between GPEs -and event sources is recorded in the system's ACPI BIOS from where it can be -read by the kernel. - -If a PCI device known to the system's ACPI BIOS signals wakeup, the GPE -associated with it (if there is one) is triggered. The GPEs associated with PCI -bridges may also be triggered in response to a wakeup signal from one of the -devices below the bridge (this also is the case for root bridges) and, for -example, native PCI PMEs from devices unknown to the system's ACPI BIOS may be -handled this way. - -A GPE may be triggered when the system is sleeping (i.e. when it is in one of -the ACPI S1-S4 states), in which case system wakeup is started by its core logic -(the device that was the source of the signal causing the system wakeup to occur -may be identified later). The GPEs used in such situations are referred to as -wakeup GPEs. - -Usually, however, GPEs are also triggered when the system is in the working -state (ACPI S0) and in that case the system's core logic generates a System -Control Interrupt (SCI) to notify the kernel of the event. Then, the SCI -handler identifies the GPE that caused the interrupt to be generated which, -in turn, allows the kernel to identify the source of the event (that may be -a PCI device signaling wakeup). The GPEs used for notifying the kernel of -events occurring while the system is in the working state are referred to as -runtime GPEs. - -Unfortunately, there is no standard way of handling wakeup signals sent by -conventional PCI devices on systems that are not ACPI-based, but there is one -for PCI Express devices. Namely, the PCI Express Base Specification introduced -a native mechanism for converting native PCI PMEs into interrupts generated by -root ports. For conventional PCI devices native PMEs are out-of-band, so they -are routed separately and they need not pass through bridges (in principle they -may be routed directly to the system's core logic), but for PCI Express devices -they are in-band messages that have to pass through the PCI Express hierarchy, -including the root port on the path from the device to the Root Complex. Thus -it was possible to introduce a mechanism by which a root port generates an -interrupt whenever it receives a PME message from one of the devices below it. -The PCI Express Requester ID of the device that sent the PME message is then -recorded in one of the root port's configuration registers from where it may be -read by the interrupt handler allowing the device to be identified. [PME -messages sent by PCI Express endpoints integrated with the Root Complex don't -pass through root ports, but instead they cause a Root Complex Event Collector -(if there is one) to generate interrupts.] - -In principle the native PCI Express PME signaling may also be used on ACPI-based -systems along with the GPEs, but to use it the kernel has to ask the system's -ACPI BIOS to release control of root port configuration registers. The ACPI -BIOS, however, is not required to allow the kernel to control these registers -and if it doesn't do that, the kernel must not modify their contents. Of course -the native PCI Express PME signaling cannot be used by the kernel in that case. - - -2. PCI Subsystem and Device Power Management -============================================ - -2.1. Device Power Management Callbacks --------------------------------------- -The PCI Subsystem participates in the power management of PCI devices in a -number of ways. First of all, it provides an intermediate code layer between -the device power management core (PM core) and PCI device drivers. -Specifically, the pm field of the PCI subsystem's struct bus_type object, -pci_bus_type, points to a struct dev_pm_ops object, pci_dev_pm_ops, containing -pointers to several device power management callbacks: - -const struct dev_pm_ops pci_dev_pm_ops = { - .prepare = pci_pm_prepare, - .complete = pci_pm_complete, - .suspend = pci_pm_suspend, - .resume = pci_pm_resume, - .freeze = pci_pm_freeze, - .thaw = pci_pm_thaw, - .poweroff = pci_pm_poweroff, - .restore = pci_pm_restore, - .suspend_noirq = pci_pm_suspend_noirq, - .resume_noirq = pci_pm_resume_noirq, - .freeze_noirq = pci_pm_freeze_noirq, - .thaw_noirq = pci_pm_thaw_noirq, - .poweroff_noirq = pci_pm_poweroff_noirq, - .restore_noirq = pci_pm_restore_noirq, - .runtime_suspend = pci_pm_runtime_suspend, - .runtime_resume = pci_pm_runtime_resume, - .runtime_idle = pci_pm_runtime_idle, -}; - -These callbacks are executed by the PM core in various situations related to -device power management and they, in turn, execute power management callbacks -provided by PCI device drivers. They also perform power management operations -involving some standard configuration registers of PCI devices that device -drivers need not know or care about. - -The structure representing a PCI device, struct pci_dev, contains several fields -that these callbacks operate on: - -struct pci_dev { - ... - pci_power_t current_state; /* Current operating state. */ - int pm_cap; /* PM capability offset in the - configuration space */ - unsigned int pme_support:5; /* Bitmask of states from which PME# - can be generated */ - unsigned int pme_interrupt:1;/* Is native PCIe PME signaling used? */ - unsigned int d1_support:1; /* Low power state D1 is supported */ - unsigned int d2_support:1; /* Low power state D2 is supported */ - unsigned int no_d1d2:1; /* D1 and D2 are forbidden */ - unsigned int wakeup_prepared:1; /* Device prepared for wake up */ - unsigned int d3_delay; /* D3->D0 transition time in ms */ - ... -}; - -They also indirectly use some fields of the struct device that is embedded in -struct pci_dev. - -2.2. Device Initialization --------------------------- -The PCI subsystem's first task related to device power management is to -prepare the device for power management and initialize the fields of struct -pci_dev used for this purpose. This happens in two functions defined in -drivers/pci/pci.c, pci_pm_init() and platform_pci_wakeup_init(). - -The first of these functions checks if the device supports native PCI PM -and if that's the case the offset of its power management capability structure -in the configuration space is stored in the pm_cap field of the device's struct -pci_dev object. Next, the function checks which PCI low-power states are -supported by the device and from which low-power states the device can generate -native PCI PMEs. The power management fields of the device's struct pci_dev and -the struct device embedded in it are updated accordingly and the generation of -PMEs by the device is disabled. - -The second function checks if the device can be prepared to signal wakeup with -the help of the platform firmware, such as the ACPI BIOS. If that is the case, -the function updates the wakeup fields in struct device embedded in the -device's struct pci_dev and uses the firmware-provided method to prevent the -device from signaling wakeup. - -At this point the device is ready for power management. For driverless devices, -however, this functionality is limited to a few basic operations carried out -during system-wide transitions to a sleep state and back to the working state. - -2.3. Runtime Device Power Management ------------------------------------- -The PCI subsystem plays a vital role in the runtime power management of PCI -devices. For this purpose it uses the general runtime power management -(runtime PM) framework described in Documentation/power/runtime_pm.txt. -Namely, it provides subsystem-level callbacks: - - pci_pm_runtime_suspend() - pci_pm_runtime_resume() - pci_pm_runtime_idle() - -that are executed by the core runtime PM routines. It also implements the -entire mechanics necessary for handling runtime wakeup signals from PCI devices -in low-power states, which at the time of this writing works for both the native -PCI Express PME signaling and the ACPI GPE-based wakeup signaling described in -Section 1. - -First, a PCI device is put into a low-power state, or suspended, with the help -of pm_schedule_suspend() or pm_runtime_suspend() which for PCI devices call -pci_pm_runtime_suspend() to do the actual job. For this to work, the device's -driver has to provide a pm->runtime_suspend() callback (see below), which is -run by pci_pm_runtime_suspend() as the first action. If the driver's callback -returns successfully, the device's standard configuration registers are saved, -the device is prepared to generate wakeup signals and, finally, it is put into -the target low-power state. - -The low-power state to put the device into is the lowest-power (highest number) -state from which it can signal wakeup. The exact method of signaling wakeup is -system-dependent and is determined by the PCI subsystem on the basis of the -reported capabilities of the device and the platform firmware. To prepare the -device for signaling wakeup and put it into the selected low-power state, the -PCI subsystem can use the platform firmware as well as the device's native PCI -PM capabilities, if supported. - -It is expected that the device driver's pm->runtime_suspend() callback will -not attempt to prepare the device for signaling wakeup or to put it into a -low-power state. The driver ought to leave these tasks to the PCI subsystem -that has all of the information necessary to perform them. - -A suspended device is brought back into the "active" state, or resumed, -with the help of pm_request_resume() or pm_runtime_resume() which both call -pci_pm_runtime_resume() for PCI devices. Again, this only works if the device's -driver provides a pm->runtime_resume() callback (see below). However, before -the driver's callback is executed, pci_pm_runtime_resume() brings the device -back into the full-power state, prevents it from signaling wakeup while in that -state and restores its standard configuration registers. Thus the driver's -callback need not worry about the PCI-specific aspects of the device resume. - -Note that generally pci_pm_runtime_resume() may be called in two different -situations. First, it may be called at the request of the device's driver, for -example if there are some data for it to process. Second, it may be called -as a result of a wakeup signal from the device itself (this sometimes is -referred to as "remote wakeup"). Of course, for this purpose the wakeup signal -is handled in one of the ways described in Section 1 and finally converted into -a notification for the PCI subsystem after the source device has been -identified. - -The pci_pm_runtime_idle() function, called for PCI devices by pm_runtime_idle() -and pm_request_idle(), executes the device driver's pm->runtime_idle() -callback, if defined, and if that callback doesn't return error code (or is not -present at all), suspends the device with the help of pm_runtime_suspend(). -Sometimes pci_pm_runtime_idle() is called automatically by the PM core (for -example, it is called right after the device has just been resumed), in which -cases it is expected to suspend the device if that makes sense. Usually, -however, the PCI subsystem doesn't really know if the device really can be -suspended, so it lets the device's driver decide by running its -pm->runtime_idle() callback. - -2.4. System-Wide Power Transitions ----------------------------------- -There are a few different types of system-wide power transitions, described in -Documentation/driver-api/pm/devices.rst. Each of them requires devices to be handled -in a specific way and the PM core executes subsystem-level power management -callbacks for this purpose. They are executed in phases such that each phase -involves executing the same subsystem-level callback for every device belonging -to the given subsystem before the next phase begins. These phases always run -after tasks have been frozen. - -2.4.1. System Suspend - -When the system is going into a sleep state in which the contents of memory will -be preserved, such as one of the ACPI sleep states S1-S3, the phases are: - - prepare, suspend, suspend_noirq. - -The following PCI bus type's callbacks, respectively, are used in these phases: - - pci_pm_prepare() - pci_pm_suspend() - pci_pm_suspend_noirq() - -The pci_pm_prepare() routine first puts the device into the "fully functional" -state with the help of pm_runtime_resume(). Then, it executes the device -driver's pm->prepare() callback if defined (i.e. if the driver's struct -dev_pm_ops object is present and the prepare pointer in that object is valid). - -The pci_pm_suspend() routine first checks if the device's driver implements -legacy PCI suspend routines (see Section 3), in which case the driver's legacy -suspend callback is executed, if present, and its result is returned. Next, if -the device's driver doesn't provide a struct dev_pm_ops object (containing -pointers to the driver's callbacks), pci_pm_default_suspend() is called, which -simply turns off the device's bus master capability and runs -pcibios_disable_device() to disable it, unless the device is a bridge (PCI -bridges are ignored by this routine). Next, the device driver's pm->suspend() -callback is executed, if defined, and its result is returned if it fails. -Finally, pci_fixup_device() is called to apply hardware suspend quirks related -to the device if necessary. - -Note that the suspend phase is carried out asynchronously for PCI devices, so -the pci_pm_suspend() callback may be executed in parallel for any pair of PCI -devices that don't depend on each other in a known way (i.e. none of the paths -in the device tree from the root bridge to a leaf device contains both of them). - -The pci_pm_suspend_noirq() routine is executed after suspend_device_irqs() has -been called, which means that the device driver's interrupt handler won't be -invoked while this routine is running. It first checks if the device's driver -implements legacy PCI suspends routines (Section 3), in which case the legacy -late suspend routine is called and its result is returned (the standard -configuration registers of the device are saved if the driver's callback hasn't -done that). Second, if the device driver's struct dev_pm_ops object is not -present, the device's standard configuration registers are saved and the routine -returns success. Otherwise the device driver's pm->suspend_noirq() callback is -executed, if present, and its result is returned if it fails. Next, if the -device's standard configuration registers haven't been saved yet (one of the -device driver's callbacks executed before might do that), pci_pm_suspend_noirq() -saves them, prepares the device to signal wakeup (if necessary) and puts it into -a low-power state. - -The low-power state to put the device into is the lowest-power (highest number) -state from which it can signal wakeup while the system is in the target sleep -state. Just like in the runtime PM case described above, the mechanism of -signaling wakeup is system-dependent and determined by the PCI subsystem, which -is also responsible for preparing the device to signal wakeup from the system's -target sleep state as appropriate. - -PCI device drivers (that don't implement legacy power management callbacks) are -generally not expected to prepare devices for signaling wakeup or to put them -into low-power states. However, if one of the driver's suspend callbacks -(pm->suspend() or pm->suspend_noirq()) saves the device's standard configuration -registers, pci_pm_suspend_noirq() will assume that the device has been prepared -to signal wakeup and put into a low-power state by the driver (the driver is -then assumed to have used the helper functions provided by the PCI subsystem for -this purpose). PCI device drivers are not encouraged to do that, but in some -rare cases doing that in the driver may be the optimum approach. - -2.4.2. System Resume - -When the system is undergoing a transition from a sleep state in which the -contents of memory have been preserved, such as one of the ACPI sleep states -S1-S3, into the working state (ACPI S0), the phases are: - - resume_noirq, resume, complete. - -The following PCI bus type's callbacks, respectively, are executed in these -phases: - - pci_pm_resume_noirq() - pci_pm_resume() - pci_pm_complete() - -The pci_pm_resume_noirq() routine first puts the device into the full-power -state, restores its standard configuration registers and applies early resume -hardware quirks related to the device, if necessary. This is done -unconditionally, regardless of whether or not the device's driver implements -legacy PCI power management callbacks (this way all PCI devices are in the -full-power state and their standard configuration registers have been restored -when their interrupt handlers are invoked for the first time during resume, -which allows the kernel to avoid problems with the handling of shared interrupts -by drivers whose devices are still suspended). If legacy PCI power management -callbacks (see Section 3) are implemented by the device's driver, the legacy -early resume callback is executed and its result is returned. Otherwise, the -device driver's pm->resume_noirq() callback is executed, if defined, and its -result is returned. - -The pci_pm_resume() routine first checks if the device's standard configuration -registers have been restored and restores them if that's not the case (this -only is necessary in the error path during a failing suspend). Next, resume -hardware quirks related to the device are applied, if necessary, and if the -device's driver implements legacy PCI power management callbacks (see -Section 3), the driver's legacy resume callback is executed and its result is -returned. Otherwise, the device's wakeup signaling mechanisms are blocked and -its driver's pm->resume() callback is executed, if defined (the callback's -result is then returned). - -The resume phase is carried out asynchronously for PCI devices, like the -suspend phase described above, which means that if two PCI devices don't depend -on each other in a known way, the pci_pm_resume() routine may be executed for -the both of them in parallel. - -The pci_pm_complete() routine only executes the device driver's pm->complete() -callback, if defined. - -2.4.3. System Hibernation - -System hibernation is more complicated than system suspend, because it requires -a system image to be created and written into a persistent storage medium. The -image is created atomically and all devices are quiesced, or frozen, before that -happens. - -The freezing of devices is carried out after enough memory has been freed (at -the time of this writing the image creation requires at least 50% of system RAM -to be free) in the following three phases: - - prepare, freeze, freeze_noirq - -that correspond to the PCI bus type's callbacks: - - pci_pm_prepare() - pci_pm_freeze() - pci_pm_freeze_noirq() - -This means that the prepare phase is exactly the same as for system suspend. -The other two phases, however, are different. - -The pci_pm_freeze() routine is quite similar to pci_pm_suspend(), but it runs -the device driver's pm->freeze() callback, if defined, instead of pm->suspend(), -and it doesn't apply the suspend-related hardware quirks. It is executed -asynchronously for different PCI devices that don't depend on each other in a -known way. - -The pci_pm_freeze_noirq() routine, in turn, is similar to -pci_pm_suspend_noirq(), but it calls the device driver's pm->freeze_noirq() -routine instead of pm->suspend_noirq(). It also doesn't attempt to prepare the -device for signaling wakeup and put it into a low-power state. Still, it saves -the device's standard configuration registers if they haven't been saved by one -of the driver's callbacks. - -Once the image has been created, it has to be saved. However, at this point all -devices are frozen and they cannot handle I/O, while their ability to handle -I/O is obviously necessary for the image saving. Thus they have to be brought -back to the fully functional state and this is done in the following phases: - - thaw_noirq, thaw, complete - -using the following PCI bus type's callbacks: - - pci_pm_thaw_noirq() - pci_pm_thaw() - pci_pm_complete() - -respectively. - -The first of them, pci_pm_thaw_noirq(), is analogous to pci_pm_resume_noirq(), -but it doesn't put the device into the full power state and doesn't attempt to -restore its standard configuration registers. It also executes the device -driver's pm->thaw_noirq() callback, if defined, instead of pm->resume_noirq(). - -The pci_pm_thaw() routine is similar to pci_pm_resume(), but it runs the device -driver's pm->thaw() callback instead of pm->resume(). It is executed -asynchronously for different PCI devices that don't depend on each other in a -known way. - -The complete phase it the same as for system resume. - -After saving the image, devices need to be powered down before the system can -enter the target sleep state (ACPI S4 for ACPI-based systems). This is done in -three phases: - - prepare, poweroff, poweroff_noirq - -where the prepare phase is exactly the same as for system suspend. The other -two phases are analogous to the suspend and suspend_noirq phases, respectively. -The PCI subsystem-level callbacks they correspond to - - pci_pm_poweroff() - pci_pm_poweroff_noirq() - -work in analogy with pci_pm_suspend() and pci_pm_poweroff_noirq(), respectively, -although they don't attempt to save the device's standard configuration -registers. - -2.4.4. System Restore - -System restore requires a hibernation image to be loaded into memory and the -pre-hibernation memory contents to be restored before the pre-hibernation system -activity can be resumed. - -As described in Documentation/driver-api/pm/devices.rst, the hibernation image is loaded -into memory by a fresh instance of the kernel, called the boot kernel, which in -turn is loaded and run by a boot loader in the usual way. After the boot kernel -has loaded the image, it needs to replace its own code and data with the code -and data of the "hibernated" kernel stored within the image, called the image -kernel. For this purpose all devices are frozen just like before creating -the image during hibernation, in the - - prepare, freeze, freeze_noirq - -phases described above. However, the devices affected by these phases are only -those having drivers in the boot kernel; other devices will still be in whatever -state the boot loader left them. - -Should the restoration of the pre-hibernation memory contents fail, the boot -kernel would go through the "thawing" procedure described above, using the -thaw_noirq, thaw, and complete phases (that will only affect the devices having -drivers in the boot kernel), and then continue running normally. - -If the pre-hibernation memory contents are restored successfully, which is the -usual situation, control is passed to the image kernel, which then becomes -responsible for bringing the system back to the working state. To achieve this, -it must restore the devices' pre-hibernation functionality, which is done much -like waking up from the memory sleep state, although it involves different -phases: - - restore_noirq, restore, complete - -The first two of these are analogous to the resume_noirq and resume phases -described above, respectively, and correspond to the following PCI subsystem -callbacks: - - pci_pm_restore_noirq() - pci_pm_restore() - -These callbacks work in analogy with pci_pm_resume_noirq() and pci_pm_resume(), -respectively, but they execute the device driver's pm->restore_noirq() and -pm->restore() callbacks, if available. - -The complete phase is carried out in exactly the same way as during system -resume. - - -3. PCI Device Drivers and Power Management -========================================== - -3.1. Power Management Callbacks -------------------------------- -PCI device drivers participate in power management by providing callbacks to be -executed by the PCI subsystem's power management routines described above and by -controlling the runtime power management of their devices. - -At the time of this writing there are two ways to define power management -callbacks for a PCI device driver, the recommended one, based on using a -dev_pm_ops structure described in Documentation/driver-api/pm/devices.rst, and the -"legacy" one, in which the .suspend(), .suspend_late(), .resume_early(), and -.resume() callbacks from struct pci_driver are used. The legacy approach, -however, doesn't allow one to define runtime power management callbacks and is -not really suitable for any new drivers. Therefore it is not covered by this -document (refer to the source code to learn more about it). - -It is recommended that all PCI device drivers define a struct dev_pm_ops object -containing pointers to power management (PM) callbacks that will be executed by -the PCI subsystem's PM routines in various circumstances. A pointer to the -driver's struct dev_pm_ops object has to be assigned to the driver.pm field in -its struct pci_driver object. Once that has happened, the "legacy" PM callbacks -in struct pci_driver are ignored (even if they are not NULL). - -The PM callbacks in struct dev_pm_ops are not mandatory and if they are not -defined (i.e. the respective fields of struct dev_pm_ops are unset) the PCI -subsystem will handle the device in a simplified default manner. If they are -defined, though, they are expected to behave as described in the following -subsections. - -3.1.1. prepare() - -The prepare() callback is executed during system suspend, during hibernation -(when a hibernation image is about to be created), during power-off after -saving a hibernation image and during system restore, when a hibernation image -has just been loaded into memory. - -This callback is only necessary if the driver's device has children that in -general may be registered at any time. In that case the role of the prepare() -callback is to prevent new children of the device from being registered until -one of the resume_noirq(), thaw_noirq(), or restore_noirq() callbacks is run. - -In addition to that the prepare() callback may carry out some operations -preparing the device to be suspended, although it should not allocate memory -(if additional memory is required to suspend the device, it has to be -preallocated earlier, for example in a suspend/hibernate notifier as described -in Documentation/driver-api/pm/notifiers.rst). - -3.1.2. suspend() - -The suspend() callback is only executed during system suspend, after prepare() -callbacks have been executed for all devices in the system. - -This callback is expected to quiesce the device and prepare it to be put into a -low-power state by the PCI subsystem. It is not required (in fact it even is -not recommended) that a PCI driver's suspend() callback save the standard -configuration registers of the device, prepare it for waking up the system, or -put it into a low-power state. All of these operations can very well be taken -care of by the PCI subsystem, without the driver's participation. - -However, in some rare case it is convenient to carry out these operations in -a PCI driver. Then, pci_save_state(), pci_prepare_to_sleep(), and -pci_set_power_state() should be used to save the device's standard configuration -registers, to prepare it for system wakeup (if necessary), and to put it into a -low-power state, respectively. Moreover, if the driver calls pci_save_state(), -the PCI subsystem will not execute either pci_prepare_to_sleep(), or -pci_set_power_state() for its device, so the driver is then responsible for -handling the device as appropriate. - -While the suspend() callback is being executed, the driver's interrupt handler -can be invoked to handle an interrupt from the device, so all suspend-related -operations relying on the driver's ability to handle interrupts should be -carried out in this callback. - -3.1.3. suspend_noirq() - -The suspend_noirq() callback is only executed during system suspend, after -suspend() callbacks have been executed for all devices in the system and -after device interrupts have been disabled by the PM core. - -The difference between suspend_noirq() and suspend() is that the driver's -interrupt handler will not be invoked while suspend_noirq() is running. Thus -suspend_noirq() can carry out operations that would cause race conditions to -arise if they were performed in suspend(). - -3.1.4. freeze() - -The freeze() callback is hibernation-specific and is executed in two situations, -during hibernation, after prepare() callbacks have been executed for all devices -in preparation for the creation of a system image, and during restore, -after a system image has been loaded into memory from persistent storage and the -prepare() callbacks have been executed for all devices. - -The role of this callback is analogous to the role of the suspend() callback -described above. In fact, they only need to be different in the rare cases when -the driver takes the responsibility for putting the device into a low-power -state. - -In that cases the freeze() callback should not prepare the device system wakeup -or put it into a low-power state. Still, either it or freeze_noirq() should -save the device's standard configuration registers using pci_save_state(). - -3.1.5. freeze_noirq() - -The freeze_noirq() callback is hibernation-specific. It is executed during -hibernation, after prepare() and freeze() callbacks have been executed for all -devices in preparation for the creation of a system image, and during restore, -after a system image has been loaded into memory and after prepare() and -freeze() callbacks have been executed for all devices. It is always executed -after device interrupts have been disabled by the PM core. - -The role of this callback is analogous to the role of the suspend_noirq() -callback described above and it very rarely is necessary to define -freeze_noirq(). - -The difference between freeze_noirq() and freeze() is analogous to the -difference between suspend_noirq() and suspend(). - -3.1.6. poweroff() - -The poweroff() callback is hibernation-specific. It is executed when the system -is about to be powered off after saving a hibernation image to a persistent -storage. prepare() callbacks are executed for all devices before poweroff() is -called. - -The role of this callback is analogous to the role of the suspend() and freeze() -callbacks described above, although it does not need to save the contents of -the device's registers. In particular, if the driver wants to put the device -into a low-power state itself instead of allowing the PCI subsystem to do that, -the poweroff() callback should use pci_prepare_to_sleep() and -pci_set_power_state() to prepare the device for system wakeup and to put it -into a low-power state, respectively, but it need not save the device's standard -configuration registers. - -3.1.7. poweroff_noirq() - -The poweroff_noirq() callback is hibernation-specific. It is executed after -poweroff() callbacks have been executed for all devices in the system. - -The role of this callback is analogous to the role of the suspend_noirq() and -freeze_noirq() callbacks described above, but it does not need to save the -contents of the device's registers. - -The difference between poweroff_noirq() and poweroff() is analogous to the -difference between suspend_noirq() and suspend(). - -3.1.8. resume_noirq() - -The resume_noirq() callback is only executed during system resume, after the -PM core has enabled the non-boot CPUs. The driver's interrupt handler will not -be invoked while resume_noirq() is running, so this callback can carry out -operations that might race with the interrupt handler. - -Since the PCI subsystem unconditionally puts all devices into the full power -state in the resume_noirq phase of system resume and restores their standard -configuration registers, resume_noirq() is usually not necessary. In general -it should only be used for performing operations that would lead to race -conditions if carried out by resume(). - -3.1.9. resume() - -The resume() callback is only executed during system resume, after -resume_noirq() callbacks have been executed for all devices in the system and -device interrupts have been enabled by the PM core. - -This callback is responsible for restoring the pre-suspend configuration of the -device and bringing it back to the fully functional state. The device should be -able to process I/O in a usual way after resume() has returned. - -3.1.10. thaw_noirq() - -The thaw_noirq() callback is hibernation-specific. It is executed after a -system image has been created and the non-boot CPUs have been enabled by the PM -core, in the thaw_noirq phase of hibernation. It also may be executed if the -loading of a hibernation image fails during system restore (it is then executed -after enabling the non-boot CPUs). The driver's interrupt handler will not be -invoked while thaw_noirq() is running. - -The role of this callback is analogous to the role of resume_noirq(). The -difference between these two callbacks is that thaw_noirq() is executed after -freeze() and freeze_noirq(), so in general it does not need to modify the -contents of the device's registers. - -3.1.11. thaw() - -The thaw() callback is hibernation-specific. It is executed after thaw_noirq() -callbacks have been executed for all devices in the system and after device -interrupts have been enabled by the PM core. - -This callback is responsible for restoring the pre-freeze configuration of -the device, so that it will work in a usual way after thaw() has returned. - -3.1.12. restore_noirq() - -The restore_noirq() callback is hibernation-specific. It is executed in the -restore_noirq phase of hibernation, when the boot kernel has passed control to -the image kernel and the non-boot CPUs have been enabled by the image kernel's -PM core. - -This callback is analogous to resume_noirq() with the exception that it cannot -make any assumption on the previous state of the device, even if the BIOS (or -generally the platform firmware) is known to preserve that state over a -suspend-resume cycle. - -For the vast majority of PCI device drivers there is no difference between -resume_noirq() and restore_noirq(). - -3.1.13. restore() - -The restore() callback is hibernation-specific. It is executed after -restore_noirq() callbacks have been executed for all devices in the system and -after the PM core has enabled device drivers' interrupt handlers to be invoked. - -This callback is analogous to resume(), just like restore_noirq() is analogous -to resume_noirq(). Consequently, the difference between restore_noirq() and -restore() is analogous to the difference between resume_noirq() and resume(). - -For the vast majority of PCI device drivers there is no difference between -resume() and restore(). - -3.1.14. complete() - -The complete() callback is executed in the following situations: - - during system resume, after resume() callbacks have been executed for all - devices, - - during hibernation, before saving the system image, after thaw() callbacks - have been executed for all devices, - - during system restore, when the system is going back to its pre-hibernation - state, after restore() callbacks have been executed for all devices. -It also may be executed if the loading of a hibernation image into memory fails -(in that case it is run after thaw() callbacks have been executed for all -devices that have drivers in the boot kernel). - -This callback is entirely optional, although it may be necessary if the -prepare() callback performs operations that need to be reversed. - -3.1.15. runtime_suspend() - -The runtime_suspend() callback is specific to device runtime power management -(runtime PM). It is executed by the PM core's runtime PM framework when the -device is about to be suspended (i.e. quiesced and put into a low-power state) -at run time. - -This callback is responsible for freezing the device and preparing it to be -put into a low-power state, but it must allow the PCI subsystem to perform all -of the PCI-specific actions necessary for suspending the device. - -3.1.16. runtime_resume() - -The runtime_resume() callback is specific to device runtime PM. It is executed -by the PM core's runtime PM framework when the device is about to be resumed -(i.e. put into the full-power state and programmed to process I/O normally) at -run time. - -This callback is responsible for restoring the normal functionality of the -device after it has been put into the full-power state by the PCI subsystem. -The device is expected to be able to process I/O in the usual way after -runtime_resume() has returned. - -3.1.17. runtime_idle() - -The runtime_idle() callback is specific to device runtime PM. It is executed -by the PM core's runtime PM framework whenever it may be desirable to suspend -the device according to the PM core's information. In particular, it is -automatically executed right after runtime_resume() has returned in case the -resume of the device has happened as a result of a spurious event. - -This callback is optional, but if it is not implemented or if it returns 0, the -PCI subsystem will call pm_runtime_suspend() for the device, which in turn will -cause the driver's runtime_suspend() callback to be executed. - -3.1.18. Pointing Multiple Callback Pointers to One Routine - -Although in principle each of the callbacks described in the previous -subsections can be defined as a separate function, it often is convenient to -point two or more members of struct dev_pm_ops to the same routine. There are -a few convenience macros that can be used for this purpose. - -The SIMPLE_DEV_PM_OPS macro declares a struct dev_pm_ops object with one -suspend routine pointed to by the .suspend(), .freeze(), and .poweroff() -members and one resume routine pointed to by the .resume(), .thaw(), and -.restore() members. The other function pointers in this struct dev_pm_ops are -unset. - -The UNIVERSAL_DEV_PM_OPS macro is similar to SIMPLE_DEV_PM_OPS, but it -additionally sets the .runtime_resume() pointer to the same value as -.resume() (and .thaw(), and .restore()) and the .runtime_suspend() pointer to -the same value as .suspend() (and .freeze() and .poweroff()). - -The SET_SYSTEM_SLEEP_PM_OPS can be used inside of a declaration of struct -dev_pm_ops to indicate that one suspend routine is to be pointed to by the -.suspend(), .freeze(), and .poweroff() members and one resume routine is to -be pointed to by the .resume(), .thaw(), and .restore() members. - -3.1.19. Driver Flags for Power Management - -The PM core allows device drivers to set flags that influence the handling of -power management for the devices by the core itself and by middle layer code -including the PCI bus type. The flags should be set once at the driver probe -time with the help of the dev_pm_set_driver_flags() function and they should not -be updated directly afterwards. - -The DPM_FLAG_NEVER_SKIP flag prevents the PM core from using the direct-complete -mechanism allowing device suspend/resume callbacks to be skipped if the device -is in runtime suspend when the system suspend starts. That also affects all of -the ancestors of the device, so this flag should only be used if absolutely -necessary. - -The DPM_FLAG_SMART_PREPARE flag instructs the PCI bus type to only return a -positive value from pci_pm_prepare() if the ->prepare callback provided by the -driver of the device returns a positive value. That allows the driver to opt -out from using the direct-complete mechanism dynamically. - -The DPM_FLAG_SMART_SUSPEND flag tells the PCI bus type that from the driver's -perspective the device can be safely left in runtime suspend during system -suspend. That causes pci_pm_suspend(), pci_pm_freeze() and pci_pm_poweroff() -to skip resuming the device from runtime suspend unless there are PCI-specific -reasons for doing that. Also, it causes pci_pm_suspend_late/noirq(), -pci_pm_freeze_late/noirq() and pci_pm_poweroff_late/noirq() to return early -if the device remains in runtime suspend in the beginning of the "late" phase -of the system-wide transition under way. Moreover, if the device is in -runtime suspend in pci_pm_resume_noirq() or pci_pm_restore_noirq(), its runtime -power management status will be changed to "active" (as it is going to be put -into D0 going forward), but if it is in runtime suspend in pci_pm_thaw_noirq(), -the function will set the power.direct_complete flag for it (to make the PM core -skip the subsequent "thaw" callbacks for it) and return. - -Setting the DPM_FLAG_LEAVE_SUSPENDED flag means that the driver prefers the -device to be left in suspend after system-wide transitions to the working state. -This flag is checked by the PM core, but the PCI bus type informs the PM core -which devices may be left in suspend from its perspective (that happens during -the "noirq" phase of system-wide suspend and analogous transitions) and next it -uses the dev_pm_may_skip_resume() helper to decide whether or not to return from -pci_pm_resume_noirq() early, as the PM core will skip the remaining resume -callbacks for the device during the transition under way and will set its -runtime PM status to "suspended" if dev_pm_may_skip_resume() returns "true" for -it. - -3.2. Device Runtime Power Management ------------------------------------- -In addition to providing device power management callbacks PCI device drivers -are responsible for controlling the runtime power management (runtime PM) of -their devices. - -The PCI device runtime PM is optional, but it is recommended that PCI device -drivers implement it at least in the cases where there is a reliable way of -verifying that the device is not used (like when the network cable is detached -from an Ethernet adapter or there are no devices attached to a USB controller). - -To support the PCI runtime PM the driver first needs to implement the -runtime_suspend() and runtime_resume() callbacks. It also may need to implement -the runtime_idle() callback to prevent the device from being suspended again -every time right after the runtime_resume() callback has returned -(alternatively, the runtime_suspend() callback will have to check if the -device should really be suspended and return -EAGAIN if that is not the case). - -The runtime PM of PCI devices is enabled by default by the PCI core. PCI -device drivers do not need to enable it and should not attempt to do so. -However, it is blocked by pci_pm_init() that runs the pm_runtime_forbid() -helper function. In addition to that, the runtime PM usage counter of -each PCI device is incremented by local_pci_probe() before executing the -probe callback provided by the device's driver. - -If a PCI driver implements the runtime PM callbacks and intends to use the -runtime PM framework provided by the PM core and the PCI subsystem, it needs -to decrement the device's runtime PM usage counter in its probe callback -function. If it doesn't do that, the counter will always be different from -zero for the device and it will never be runtime-suspended. The simplest -way to do that is by calling pm_runtime_put_noidle(), but if the driver -wants to schedule an autosuspend right away, for example, it may call -pm_runtime_put_autosuspend() instead for this purpose. Generally, it -just needs to call a function that decrements the devices usage counter -from its probe routine to make runtime PM work for the device. - -It is important to remember that the driver's runtime_suspend() callback -may be executed right after the usage counter has been decremented, because -user space may already have caused the pm_runtime_allow() helper function -unblocking the runtime PM of the device to run via sysfs, so the driver must -be prepared to cope with that. - -The driver itself should not call pm_runtime_allow(), though. Instead, it -should let user space or some platform-specific code do that (user space can -do it via sysfs as stated above), but it must be prepared to handle the -runtime PM of the device correctly as soon as pm_runtime_allow() is called -(which may happen at any time, even before the driver is loaded). - -When the driver's remove callback runs, it has to balance the decrementation -of the device's runtime PM usage counter at the probe time. For this reason, -if it has decremented the counter in its probe callback, it must run -pm_runtime_get_noresume() in its remove callback. [Since the core carries -out a runtime resume of the device and bumps up the device's usage counter -before running the driver's remove callback, the runtime PM of the device -is effectively disabled for the duration of the remove execution and all -runtime PM helper functions incrementing the device's usage counter are -then effectively equivalent to pm_runtime_get_noresume().] - -The runtime PM framework works by processing requests to suspend or resume -devices, or to check if they are idle (in which cases it is reasonable to -subsequently request that they be suspended). These requests are represented -by work items put into the power management workqueue, pm_wq. Although there -are a few situations in which power management requests are automatically -queued by the PM core (for example, after processing a request to resume a -device the PM core automatically queues a request to check if the device is -idle), device drivers are generally responsible for queuing power management -requests for their devices. For this purpose they should use the runtime PM -helper functions provided by the PM core, discussed in -Documentation/power/runtime_pm.txt. - -Devices can also be suspended and resumed synchronously, without placing a -request into pm_wq. In the majority of cases this also is done by their -drivers that use helper functions provided by the PM core for this purpose. - -For more information on the runtime PM of devices refer to -Documentation/power/runtime_pm.txt. - - -4.

If that value is PM_QOS_LATENCY_ANY, in turn, and +the hardware supports a special "no requirement" setting, the callback is +expected to use it. That allows software to prevent the hardware from +automatically updating the device's latency tolerance in response to its power +state changes (e.g. during transitions from D3cold to D0), which generally may +be done in the autonomous latency tolerance control mode. + +If .set_latency_tolerance() is present for the device, sysfs attribute +pm_qos_latency_tolerance_us will be present in the devivce's power directory. +Then, user space can use that attribute to specify its latency tolerance +requirement for the device, if any. Writing "any" to it means "no requirement, +but do not let the hardware control latency tolerance" and writing "auto" to it +allows the hardware to be switched to the autonomous mode if there are no other +requirements from the kernel side in the device's list. + +Kernel code can use the functions described above along with the +DEV_PM_QOS_LATENCY_TOLERANCE device PM QoS type to add, remove and update +latency tolerance requirements for devices. diff --git a/Documentation/power/pm_qos_interface.txt b/Documentation/power/pm_qos_interface.txt deleted file mode 100644 index 19c5f7b1a7ba..000000000000 --- a/Documentation/power/pm_qos_interface.txt +++ /dev/null @@ -1,212 +0,0 @@ -PM Quality Of Service Interface. - -This interface provides a kernel and user mode interface for registering -performance expectations by drivers, subsystems and user space applications on -one of the parameters. - -Two different PM QoS frameworks are available: -1.

One device PM QoS flag is defined currently: PM_QOS_FLAG_NO_POWER_OFF. - -Note: The aggregated target values are implemented in such a way that reading -the aggregated value does not require any locking mechanism. - - -From kernel mode the use of this interface is the following: - -int dev_pm_qos_add_request(device, handle, type, value): -Will insert an element into the list for that identified device with the -target value. Upon change to this list the new target is recomputed and any -registered notifiers are called only if the target value is now different. -Clients of dev_pm_qos need to save the handle for future use in other -dev_pm_qos API functions. - -int dev_pm_qos_update_request(handle, new_value): -Will update the list element pointed to by the handle with the new target value -and recompute the new aggregated target, calling the notification trees if the -target is changed. - -int dev_pm_qos_remove_request(handle): -Will remove the element. After removal it will update the aggregate target and -call the notification trees if the target was changed as a result of removing -the request. - -s32 dev_pm_qos_read_value(device): -Returns the aggregated value for a given device's constraints list. - -enum pm_qos_flags_status dev_pm_qos_flags(device, mask) -Check PM QoS flags of the given device against the given mask of flags. -The meaning of the return values is as follows: - PM_QOS_FLAGS_ALL: All flags from the mask are set - PM_QOS_FLAGS_SOME: Some flags from the mask are set - PM_QOS_FLAGS_NONE: No flags from the mask are set - PM_QOS_FLAGS_UNDEFINED: The device's PM QoS structure has not been - initialized or the list of requests is empty. - -int dev_pm_qos_add_ancestor_request(dev, handle, type, value) -Add a PM QoS request for the first direct ancestor of the given device whose -power.ignore_children flag is unset (for DEV_PM_QOS_RESUME_LATENCY requests) -or whose power.set_latency_tolerance callback pointer is not NULL (for -DEV_PM_QOS_LATENCY_TOLERANCE requests). - -int dev_pm_qos_expose_latency_limit(device, value) -Add a request to the device's PM QoS list of resume latency constraints and -create a sysfs attribute pm_qos_resume_latency_us under the device's power -directory allowing user space to manipulate that request. - -void dev_pm_qos_hide_latency_limit(device) -Drop the request added by dev_pm_qos_expose_latency_limit() from the device's -PM QoS list of resume latency constraints and remove sysfs attribute -pm_qos_resume_latency_us from the device's power directory. - -int dev_pm_qos_expose_flags(device, value) -Add a request to the device's PM QoS list of flags and create sysfs attribute -pm_qos_no_power_off under the device's power directory allowing user space to -change the value of the PM_QOS_FLAG_NO_POWER_OFF flag. - -void dev_pm_qos_hide_flags(device) -Drop the request added by dev_pm_qos_expose_flags() from the device's PM QoS list -of flags and remove sysfs attribute pm_qos_no_power_off from the device's power -directory. - -Notification mechanisms: -The per-device PM QoS framework has a per-device notification tree. - -int dev_pm_qos_add_notifier(device, notifier): -Adds a notification callback function for the device. -The callback is called when the aggregated value of the device constraints list -is changed (for resume latency device PM QoS only). - -int dev_pm_qos_remove_notifier(device, notifier): -Removes the notification callback function for the device. - - -Active state latency tolerance - -This device PM QoS type is used to support systems in which hardware may switch -to energy-saving operation modes on the fly. In those systems, if the operation -mode chosen by the hardware attempts to save energy in an overly aggressive way, -it may cause excess latencies to be visible to software, causing it to miss -certain protocol requirements or target frame or sample rates etc. - -If there is a latency tolerance control mechanism for a given device available -to software, the .set_latency_tolerance callback in that device's dev_pm_info -structure should be populated. The routine pointed to by it is should implement -whatever is necessary to transfer the effective requirement value to the -hardware. - -Whenever the effective latency tolerance changes for the device, its -.set_latency_tolerance() callback will be executed and the effective value will -be passed to it. If that value is negative, which means that the list of -latency tolerance requirements for the device is empty, the callback is expected -to switch the underlying hardware latency tolerance control mechanism to an -autonomous mode if available. If that value is PM_QOS_LATENCY_ANY, in turn, and -the hardware supports a special "no requirement" setting, the callback is -expected to use it. That allows software to prevent the hardware from -automatically updating the device's latency tolerance in response to its power -state changes (e.g. during transitions from D3cold to D0), which generally may -be done in the autonomous latency tolerance control mode. - -If .set_latency_tolerance() is present for the device, sysfs attribute -pm_qos_latency_tolerance_us will be present in the devivce's power directory. -Then, user space can use that attribute to specify its latency tolerance -requirement for the device, if any. Writing "any" to it means "no requirement, -but do not let the hardware control latency tolerance" and writing "auto" to it -allows the hardware to be switched to the autonomous mode if there are no other -requirements from the kernel side in the device's list. - -Kernel code can use the functions described above along with the -DEV_PM_QOS_LATENCY_TOLERANCE device PM QoS type to add, remove and update -latency tolerance requirements for devices. diff --git a/Documentation/power/power_supply_class.rst b/Documentation/power/power_supply_class.rst new file mode 100644 index 000000000000..3f2c3fe38a61 --- /dev/null +++ b/Documentation/power/power_supply_class.rst @@ -0,0 +1,282 @@ +======================== +Linux power supply class +======================== + +Synopsis +~~~~~~~~ +Power supply class used to represent battery, UPS, AC or DC power supply +properties to user-space. + +It defines core set of attributes, which should be applicable to (almost) +every power supply out there.

This can be achieved by -calling :- - -int regulator_set_mode(struct regulator *regulator, unsigned int mode); -unsigned int regulator_get_mode(struct regulator *regulator); - -Direct mode will only be used by consumers that *know* about the regulator and -are not sharing the regulator with other consumers. - - -6. Regulator Events -=================== -Regulators can notify consumers of external events. Events could be received by -consumers under regulator stress or failure conditions. - -Consumers can register interest in regulator events by calling :- - -int regulator_register_notifier(struct regulator *regulator, - struct notifier_block *nb); - -Consumers can unregister interest by calling :- - -int regulator_unregister_notifier(struct regulator *regulator, - struct notifier_block *nb); - -Regulators use the kernel notifier framework to send event to their interested -consumers. - -7. Regulator Direct Register Access -=================================== -Some kinds of power management hardware or firmware are designed such that -they need to do low-level hardware access to regulators, with no involvement -from the kernel. Examples of such devices are: - -- clocksource with a voltage-controlled oscillator and control logic to change - the supply voltage over I2C to achieve a desired output clock rate -- thermal management firmware that can issue an arbitrary I2C transaction to - perform system poweroff during overtemperature conditions - -To set up such a device/firmware, various parameters like I2C address of the -regulator, addresses of various regulator registers etc. need to be configured -to it. The regulator framework provides the following helpers for querying -these details. - -Bus-specific details, like I2C addresses or transfer rates are handled by the -regmap framework. To get the regulator's regmap (if supported), use :- - -struct regmap *regulator_get_regmap(struct regulator *regulator); - -To obtain the hardware register offset and bitmask for the regulator's voltage -selector register, use :- - -int regulator_get_hardware_vsel_register(struct regulator *regulator, - unsigned *vsel_reg, - unsigned *vsel_mask); - -To convert a regulator framework voltage selector code (used by -regulator_list_voltage) to a hardware-specific voltage selector that can be -directly written to the voltage selector register, use :- - -int regulator_list_hardware_vsel(struct regulator *regulator, - unsigned selector); diff --git a/Documentation/power/regulator/design.rst b/Documentation/power/regulator/design.rst new file mode 100644 index 000000000000..3b09c6841dc4 --- /dev/null +++ b/Documentation/power/regulator/design.rst @@ -0,0 +1,38 @@ +========================== +Regulator API design notes +========================== + +This document provides a brief, partially structured, overview of some +of the design considerations which impact the regulator API design. + +Safety +------ + + - Errors in regulator configuration can have very serious consequences + for the system, potentially including lasting hardware damage. + - It is not possible to automatically determine the power configuration + of the system - software-equivalent variants of the same chip may + have different power requirements, and not all components with power + requirements are visible to software. + +.. note:: + + The API should make no changes to the hardware state unless it has + specific knowledge that these changes are safe to perform on this + particular system. + +Consumer use cases +------------------ + + - The overwhelming majority of devices in a system will have no + requirement to do any runtime configuration of their power beyond + being able to turn it on or off. + + - Many of the power supplies in the system will be shared between many + different consumers. + +.. note:: + + The consumer API should be structured so that these use cases are + very easy to handle and so that consumers will work with shared + supplies without any additional effort. diff --git a/Documentation/power/regulator/design.txt b/Documentation/power/regulator/design.txt deleted file mode 100644 index fdd919b96830..000000000000 --- a/Documentation/power/regulator/design.txt +++ /dev/null @@ -1,33 +0,0 @@ -Regulator API design notes -========================== - -This document provides a brief, partially structured, overview of some -of the design considerations which impact the regulator API design. - -Safety ------- - - - Errors in regulator configuration can have very serious consequences - for the system, potentially including lasting hardware damage. - - It is not possible to automatically determine the power configuration - of the system - software-equivalent variants of the same chip may - have different power requirements, and not all components with power - requirements are visible to software. - - => The API should make no changes to the hardware state unless it has - specific knowledge that these changes are safe to perform on this - particular system. - -Consumer use cases ------------------- - - - The overwhelming majority of devices in a system will have no - requirement to do any runtime configuration of their power beyond - being able to turn it on or off. - - - Many of the power supplies in the system will be shared between many - different consumers. - - => The consumer API should be structured so that these use cases are - very easy to handle and so that consumers will work with shared - supplies without any additional effort. diff --git a/Documentation/power/regulator/machine.rst b/Documentation/power/regulator/machine.rst new file mode 100644 index 000000000000..22fffefaa3ad --- /dev/null +++ b/Documentation/power/regulator/machine.rst @@ -0,0 +1,97 @@ +================================== +Regulator Machine Driver Interface +================================== + +The regulator machine driver interface is intended for board/machine specific +initialisation code to configure the regulator subsystem. + +Consider the following machine:: + + Regulator-1 -+-> Regulator-2 --> [Consumer A @ 1.8 - 2.0V] + | + +-> [Consumer B @ 3.3V] + +The drivers for consumers A & B must be mapped to the correct regulator in +order to control their power supplies.

Wysocki , Novell Inc. + +(C) 2010 Alan Stern + +(C) 2014 Intel Corp., Rafael J. Wysocki + +1. Introduction +=============== + +Support for runtime power management (runtime PM) of I/O devices is provided +at the power management core (PM core) level by means of: + +* The power management workqueue pm_wq in which bus types and device drivers can + put their PM-related work items. It is strongly recommended that pm_wq be + used for queuing all work items related to runtime PM, because this allows + them to be synchronized with system-wide power transitions (suspend to RAM, + hibernation and resume from system sleep states). pm_wq is declared in + include/linux/pm_runtime.h and defined in kernel/power/main.c. + +* A number of runtime PM fields in the 'power' member of 'struct device' (which + is of the type 'struct dev_pm_info', defined in include/linux/pm.h) that can + be used for synchronizing runtime PM operations with one another. + +* Three device runtime PM callbacks in 'struct dev_pm_ops' (defined in + include/linux/pm.h). + +* A set of helper functions defined in drivers/base/power/runtime.c that can be + used for carrying out runtime PM operations in such a way that the + synchronization between them is taken care of by the PM core. Bus types and + device drivers are encouraged to use these functions. + +The runtime PM callbacks present in 'struct dev_pm_ops', the device runtime PM +fields of 'struct dev_pm_info' and the core helper functions provided for +runtime PM are described below. + +2. Device Runtime PM Callbacks +============================== + +There are three device runtime PM callbacks defined in 'struct dev_pm_ops':: + + struct dev_pm_ops { + ... + int (*runtime_suspend)(struct device *dev); + int (*runtime_resume)(struct device *dev); + int (*runtime_idle)(struct device *dev); + ... + }; + +The ->runtime_suspend(), ->runtime_resume() and ->runtime_idle() callbacks +are executed by the PM core for the device's subsystem that may be either of +the following: + + 1. PM domain of the device, if the device's PM domain object, dev->pm_domain, + is present. + + 2. Device type of the device, if both dev->type and dev->type->pm are present. + + 3. Device class of the device, if both dev->class and dev->class->pm are + present. + + 4. Bus type of the device, if both dev->bus and dev->bus->pm are present. + +If the subsystem chosen by applying the above rules doesn't provide the relevant +callback, the PM core will invoke the corresponding driver callback stored in +dev->driver->pm directly (if present). + +The PM core always checks which callback to use in the order given above, so the +priority order of callbacks from high to low is: PM domain, device type, class +and bus type. Moreover, the high-priority one will always take precedence over +a low-priority one. The PM domain, bus type, device type and class callbacks +are referred to as subsystem-level callbacks in what follows. + +By default, the callbacks are always invoked in process context with interrupts +enabled. However, the pm_runtime_irq_safe() helper function can be used to tell +the PM core that it is safe to run the ->runtime_suspend(), ->runtime_resume() +and ->runtime_idle() callbacks for the given device in atomic context with +interrupts disabled. This implies that the callback routines in question must +not block or sleep, but it also means that the synchronous helper functions +listed at the end of Section 4 may be used for that device within an interrupt +handler or generally in an atomic context. + +The subsystem-level suspend callback, if present, is _entirely_ _responsible_ +for handling the suspend of the device as appropriate, which may, but need not +include executing the device driver's own ->runtime_suspend() callback (from the +PM core's point of view it is not necessary to implement a ->runtime_suspend() +callback in a device driver as long as the subsystem-level suspend callback +knows what to do to handle the device). + + * Once the subsystem-level suspend callback (or the driver suspend callback, + if invoked directly) has completed successfully for the given device, the PM + core regards the device as suspended, which need not mean that it has been + put into a low power state. It is supposed to mean, however, that the + device will not process data and will not communicate with the CPU(s) and + RAM until the appropriate resume callback is executed for it. The runtime + PM status of a device after successful execution of the suspend callback is + 'suspended'. + + * If the suspend callback returns -EBUSY or -EAGAIN, the device's runtime PM + status remains 'active', which means that the device _must_ be fully + operational afterwards. + + * If the suspend callback returns an error code different from -EBUSY and + -EAGAIN, the PM core regards this as a fatal error and will refuse to run + the helper functions described in Section 4 for the device until its status + is directly set to either 'active', or 'suspended' (the PM core provides + special helper functions for this purpose). + +In particular, if the driver requires remote wakeup capability (i.e. hardware +mechanism allowing the device to request a change of its power state, such as +PCI PME) for proper functioning and device_can_wakeup() returns 'false' for the +device, then ->runtime_suspend() should return -EBUSY. On the other hand, if +device_can_wakeup() returns 'true' for the device and the device is put into a +low-power state during the execution of the suspend callback, it is expected +that remote wakeup will be enabled for the device. Generally, remote wakeup +should be enabled for all input devices put into low-power states at run time. + +The subsystem-level resume callback, if present, is **entirely responsible** for +handling the resume of the device as appropriate, which may, but need not +include executing the device driver's own ->runtime_resume() callback (from the +PM core's point of view it is not necessary to implement a ->runtime_resume() +callback in a device driver as long as the subsystem-level resume callback knows +what to do to handle the device). + + * Once the subsystem-level resume callback (or the driver resume callback, if + invoked directly) has completed successfully, the PM core regards the device + as fully operational, which means that the device _must_ be able to complete + I/O operations as needed. The runtime PM status of the device is then + 'active'. + + * If the resume callback returns an error code, the PM core regards this as a + fatal error and will refuse to run the helper functions described in Section + 4 for the device, until its status is directly set to either 'active', or + 'suspended' (by means of special helper functions provided by the PM core + for this purpose). + +The idle callback (a subsystem-level one, if present, or the driver one) is +executed by the PM core whenever the device appears to be idle, which is +indicated to the PM core by two counters, the device's usage counter and the +counter of 'active' children of the device. + + * If any of these counters is decreased using a helper function provided by + the PM core and it turns out to be equal to zero, the other counter is + checked. If that counter also is equal to zero, the PM core executes the + idle callback with the device as its argument. + +The action performed by the idle callback is totally dependent on the subsystem +(or driver) in question, but the expected and recommended action is to check +if the device can be suspended (i.e. if all of the conditions necessary for +suspending the device are satisfied) and to queue up a suspend request for the +device in that case. If there is no idle callback, or if the callback returns +0, then the PM core will attempt to carry out a runtime suspend of the device, +also respecting devices configured for autosuspend. In essence this means a +call to pm_runtime_autosuspend() (do note that drivers needs to update the +device last busy mark, pm_runtime_mark_last_busy(), to control the delay under +this circumstance). To prevent this (for example, if the callback routine has +started a delayed suspend), the routine must return a non-zero value. Negative +error return codes are ignored by the PM core. + +The helper functions provided by the PM core, described in Section 4, guarantee +that the following constraints are met with respect to runtime PM callbacks for +one device: + +(1) The callbacks are mutually exclusive (e.g. it is forbidden to execute + ->runtime_suspend() in parallel with ->runtime_resume() or with another + instance of ->runtime_suspend() for the same device) with the exception that + ->runtime_suspend() or ->runtime_resume() can be executed in parallel with + ->runtime_idle() (although ->runtime_idle() will not be started while any + of the other callbacks is being executed for the same device). + +(2) ->runtime_idle() and ->runtime_suspend() can only be executed for 'active' + devices (i.e. the PM core will only execute ->runtime_idle() or + ->runtime_suspend() for the devices the runtime PM status of which is + 'active'). + +(3) ->runtime_idle() and ->runtime_suspend() can only be executed for a device + the usage counter of which is equal to zero _and_ either the counter of + 'active' children of which is equal to zero, or the 'power.ignore_children' + flag of which is set. + +(4) ->runtime_resume() can only be executed for 'suspended' devices (i.e. the + PM core will only execute ->runtime_resume() for the devices the runtime + PM status of which is 'suspended'). + +Additionally, the helper functions provided by the PM core obey the following +rules: + + * If ->runtime_suspend() is about to be executed or there's a pending request + to execute it, ->runtime_idle() will not be executed for the same device. + + * A request to execute or to schedule the execution of ->runtime_suspend() + will cancel any pending requests to execute ->runtime_idle() for the same + device. + + * If ->runtime_resume() is about to be executed or there's a pending request + to execute it, the other callbacks will not be executed for the same device. + + * A request to execute ->runtime_resume() will cancel any pending or + scheduled requests to execute the other callbacks for the same device, + except for scheduled autosuspends. + +3.

Runtime PM Initialization, Device Probing and Removal +======================================================== + +Initially, the runtime PM is disabled for all devices, which means that the +majority of the runtime PM helper functions described in Section 4 will return +-EAGAIN until pm_runtime_enable() is called for the device. + +In addition to that, the initial runtime PM status of all devices is +'suspended', but it need not reflect the actual physical state of the device. +Thus, if the device is initially active (i.e. it is able to process I/O), its +runtime PM status must be changed to 'active', with the help of +pm_runtime_set_active(), before pm_runtime_enable() is called for the device. + +However, if the device has a parent and the parent's runtime PM is enabled, +calling pm_runtime_set_active() for the device will affect the parent, unless +the parent's 'power.ignore_children' flag is set. Namely, in that case the +parent won't be able to suspend at run time, using the PM core's helper +functions, as long as the child's status is 'active', even if the child's +runtime PM is still disabled (i.e. pm_runtime_enable() hasn't been called for +the child yet or pm_runtime_disable() has been called for it). For this reason, +once pm_runtime_set_active() has been called for the device, pm_runtime_enable() +should be called for it too as soon as reasonably possible or its runtime PM +status should be changed back to 'suspended' with the help of +pm_runtime_set_suspended(). + +If the default initial runtime PM status of the device (i.e. 'suspended') +reflects the actual state of the device, its bus type's or its driver's +->probe() callback will likely need to wake it up using one of the PM core's +helper functions described in Section 4. In that case, pm_runtime_resume() +should be used. Of course, for this purpose the device's runtime PM has to be +enabled earlier by calling pm_runtime_enable(). + +Note, if the device may execute pm_runtime calls during the probe (such as +if it is registers with a subsystem that may call back in) then the +pm_runtime_get_sync() call paired with a pm_runtime_put() call will be +appropriate to ensure that the device is not put back to sleep during the +probe. This can happen with systems such as the network device layer. + +It may be desirable to suspend the device once ->probe() has finished. +Therefore the driver core uses the asynchronous pm_request_idle() to submit a +request to execute the subsystem-level idle callback for the device at that +time. A driver that makes use of the runtime autosuspend feature, may want to +update the last busy mark before returning from ->probe(). + +Moreover, the driver core prevents runtime PM callbacks from racing with the bus +notifier callback in __device_release_driver(), which is necessary, because the +notifier is used by some subsystems to carry out operations affecting the +runtime PM functionality. It does so by calling pm_runtime_get_sync() before +driver_sysfs_remove() and the BUS_NOTIFY_UNBIND_DRIVER notifications. This +resumes the device if it's in the suspended state and prevents it from +being suspended again while those routines are being executed. + +To allow bus types and drivers to put devices into the suspended state by +calling pm_runtime_suspend() from their ->remove() routines, the driver core +executes pm_runtime_put_sync() after running the BUS_NOTIFY_UNBIND_DRIVER +notifications in __device_release_driver(). This requires bus types and +drivers to make their ->remove() callbacks avoid races with runtime PM directly, +but also it allows of more flexibility in the handling of devices during the +removal of their drivers. + +Drivers in ->remove() callback should undo the runtime PM changes done +in ->probe(). Usually this means calling pm_runtime_disable(), +pm_runtime_dont_use_autosuspend() etc. + +The user space can effectively disallow the driver of the device to power manage +it at run time by changing the value of its /sys/devices/.../power/control +attribute to "on", which causes pm_runtime_forbid() to be called. In principle, +this mechanism may also be used by the driver to effectively turn off the +runtime power management of the device until the user space turns it on. +Namely, during the initialization the driver can make sure that the runtime PM +status of the device is 'active' and call pm_runtime_forbid(). It should be +noted, however, that if the user space has already intentionally changed the +value of /sys/devices/.../power/control to "auto" to allow the driver to power +manage the device at run time, the driver may confuse it by using +pm_runtime_forbid() this way. + +6. Runtime PM and System Sleep +============================== + +Runtime PM and system sleep (i.e., system suspend and hibernation, also known +as suspend-to-RAM and suspend-to-disk) interact with each other in a couple of +ways. If a device is active when a system sleep starts, everything is +straightforward. But what should happen if the device is already suspended? + +The device may have different wake-up settings for runtime PM and system sleep. +For example, remote wake-up may be enabled for runtime suspend but disallowed +for system sleep (device_may_wakeup(dev) returns 'false'). When this happens, +the subsystem-level system suspend callback is responsible for changing the +device's wake-up setting (it may leave that to the device driver's system +suspend routine). It may be necessary to resume the device and suspend it again +in order to do so. The same is true if the driver uses different power levels +or other settings for runtime suspend and system sleep. + +During system resume, the simplest approach is to bring all devices back to full +power, even if they had been suspended before the system suspend began. There +are several reasons for this, including: + + * The device might need to switch power levels, wake-up settings, etc. + + * Remote wake-up events might have been lost by the firmware. + + * The device's children may need the device to be at full power in order + to resume themselves. + + * The driver's idea of the device state may not agree with the device's + physical state. This can happen during resume from hibernation. + + * The device might need to be reset. + + * Even though the device was suspended, if its usage counter was > 0 then most + likely it would need a runtime resume in the near future anyway. + +If the device had been suspended before the system suspend began and it's +brought back to full power during resume, then its runtime PM status will have +to be updated to reflect the actual post-system sleep status. The way to do +this is: + + - pm_runtime_disable(dev); + - pm_runtime_set_active(dev); + - pm_runtime_enable(dev); + +The PM core always increments the runtime usage counter before calling the +->suspend() callback and decrements it after calling the ->resume() callback. +Hence disabling runtime PM temporarily like this will not cause any runtime +suspend attempts to be permanently lost. If the usage count goes to zero +following the return of the ->resume() callback, the ->runtime_idle() callback +will be invoked as usual. + +On some systems, however, system sleep is not entered through a global firmware +or hardware operation. Instead, all hardware components are put into low-power +states directly by the kernel in a coordinated way. Then, the system sleep +state effectively follows from the states the hardware components end up in +and the system is woken up from that state by a hardware interrupt or a similar +mechanism entirely under the kernel's control. As a result, the kernel never +gives control away and the states of all devices during resume are precisely +known to it. If that is the case and none of the situations listed above takes +place (in particular, if the system is not waking up from hibernation), it may +be more efficient to leave the devices that had been suspended before the system +suspend began in the suspended state. + +To this end, the PM core provides a mechanism allowing some coordination between +different levels of device hierarchy. Namely, if a system suspend .prepare() +callback returns a positive number for a device, that indicates to the PM core +that the device appears to be runtime-suspended and its state is fine, so it +may be left in runtime suspend provided that all of its descendants are also +left in runtime suspend. If that happens, the PM core will not execute any +system suspend and resume callbacks for all of those devices, except for the +complete callback, which is then entirely responsible for handling the device +as appropriate. This only applies to system suspend transitions that are not +related to hibernation (see Documentation/driver-api/pm/devices.rst for more +information). + +The PM core does its best to reduce the probability of race conditions between +the runtime PM and system suspend/resume (and hibernation) callbacks by carrying +out the following operations: + + * During system suspend pm_runtime_get_noresume() is called for every device + right before executing the subsystem-level .prepare() callback for it and + pm_runtime_barrier() is called for every device right before executing the + subsystem-level .suspend() callback for it. In addition to that the PM core + calls __pm_runtime_disable() with 'false' as the second argument for every + device right before executing the subsystem-level .suspend_late() callback + for it. + + * During system resume pm_runtime_enable() and pm_runtime_put() are called for + every device right after executing the subsystem-level .resume_early() + callback and right after executing the subsystem-level .complete() callback + for it, respectively. + +7. Generic subsystem callbacks + +Subsystems may wish to conserve code space by using the set of generic power +management callbacks provided by the PM core, defined in +driver/base/power/generic_ops.c: + + `int pm_generic_runtime_suspend(struct device *dev);` + - invoke the ->runtime_suspend() callback provided by the driver of this + device and return its result, or return 0 if not defined + + `int pm_generic_runtime_resume(struct device *dev);` + - invoke the ->runtime_resume() callback provided by the driver of this + device and return its result, or return 0 if not defined + + `int pm_generic_suspend(struct device *dev);` + - if the device has not been suspended at run time, invoke the ->suspend() + callback provided by its driver and return its result, or return 0 if not + defined + + `int pm_generic_suspend_noirq(struct device *dev);` + - if pm_runtime_suspended(dev) returns "false", invoke the ->suspend_noirq() + callback provided by the device's driver and return its result, or return + 0 if not defined + + `int pm_generic_resume(struct device *dev);` + - invoke the ->resume() callback provided by the driver of this device and, + if successful, change the device's runtime PM status to 'active' + + `int pm_generic_resume_noirq(struct device *dev);` + - invoke the ->resume_noirq() callback provided by the driver of this device + + `int pm_generic_freeze(struct device *dev);` + - if the device has not been suspended at run time, invoke the ->freeze() + callback provided by its driver and return its result, or return 0 if not + defined + + `int pm_generic_freeze_noirq(struct device *dev);` + - if pm_runtime_suspended(dev) returns "false", invoke the ->freeze_noirq() + callback provided by the device's driver and return its result, or return + 0 if not defined + + `int pm_generic_thaw(struct device *dev);` + - if the device has not been suspended at run time, invoke the ->thaw() + callback provided by its driver and return its result, or return 0 if not + defined + + `int pm_generic_thaw_noirq(struct device *dev);` + - if pm_runtime_suspended(dev) returns "false", invoke the ->thaw_noirq() + callback provided by the device's driver and return its result, or return + 0 if not defined + + `int pm_generic_poweroff(struct device *dev);` + - if the device has not been suspended at run time, invoke the ->poweroff() + callback provided by its driver and return its result, or return 0 if not + defined + + `int pm_generic_poweroff_noirq(struct device *dev);` + - if pm_runtime_suspended(dev) returns "false", run the ->poweroff_noirq() + callback provided by the device's driver and return its result, or return + 0 if not defined + + `int pm_generic_restore(struct device *dev);` + - invoke the ->restore() callback provided by the driver of this device and, + if successful, change the device's runtime PM status to 'active' + + `int pm_generic_restore_noirq(struct device *dev);` + - invoke the ->restore_noirq() callback provided by the device's driver + +These functions are the defaults used by the PM core, if a subsystem doesn't +provide its own callbacks for ->runtime_idle(), ->runtime_suspend(), +->runtime_resume(), ->suspend(), ->suspend_noirq(), ->resume(), +->resume_noirq(), ->freeze(), ->freeze_noirq(), ->thaw(), ->thaw_noirq(), +->poweroff(), ->poweroff_noirq(), ->restore(), ->restore_noirq() in the +subsystem-level dev_pm_ops structure. + +Device drivers that wish to use the same function as a system suspend, freeze, +poweroff and runtime suspend callback, and similarly for system resume, thaw, +restore, and runtime resume, can achieve this with the help of the +UNIVERSAL_DEV_PM_OPS macro defined in include/linux/pm.h (possibly setting its +last argument to NULL). + +8. "No-Callback" Devices +======================== + +Some "devices" are only logical sub-devices of their parent and cannot be +power-managed on their own. (The prototype example is a USB interface. Entire +USB devices can go into low-power mode or send wake-up requests, but neither is +possible for individual interfaces.) The drivers for these devices have no +need of runtime PM callbacks; if the callbacks did exist, ->runtime_suspend() +and ->runtime_resume() would always return 0 without doing anything else and +->runtime_idle() would always call pm_runtime_suspend(). + +Subsystems can tell the PM core about these devices by calling +pm_runtime_no_callbacks(). This should be done after the device structure is +initialized and before it is registered (although after device registration is +also okay). The routine will set the device's power.no_callbacks flag and +prevent the non-debugging runtime PM sysfs attributes from being created. + +When power.no_callbacks is set, the PM core will not invoke the +->runtime_idle(), ->runtime_suspend(), or ->runtime_resume() callbacks. +Instead it will assume that suspends and resumes always succeed and that idle +devices should be suspended. + +As a consequence, the PM core will never directly inform the device's subsystem +or driver about runtime power changes. Instead, the driver for the device's +parent must take responsibility for telling the device's driver when the +parent's power state changes. + +9. Autosuspend, or automatically-delayed suspends +================================================= + +Changing a device's power state isn't free; it requires both time and energy. +A device should be put in a low-power state only when there's some reason to +think it will remain in that state for a substantial time. A common heuristic +says that a device which hasn't been used for a while is liable to remain +unused; following this advice, drivers should not allow devices to be suspended +at runtime until they have been inactive for some minimum period. Even when +the heuristic ends up being non-optimal, it will still prevent devices from +"bouncing" too rapidly between low-power and full-power states. + +The term "autosuspend" is an historical remnant. It doesn't mean that the +device is automatically suspended (the subsystem or driver still has to call +the appropriate PM routines); rather it means that runtime suspends will +automatically be delayed until the desired period of inactivity has elapsed. + +Inactivity is determined based on the power.last_busy field. Drivers should +call pm_runtime_mark_last_busy() to update this field after carrying out I/O, +typically just before calling pm_runtime_put_autosuspend(). The desired length +of the inactivity period is a matter of policy. Subsystems can set this length +initially by calling pm_runtime_set_autosuspend_delay(), but after device +registration the length should be controlled by user space, using the +/sys/devices/.../power/autosuspend_delay_ms attribute. + +In order to use autosuspend, subsystems or drivers must call +pm_runtime_use_autosuspend() (preferably before registering the device), and +thereafter they should use the various `*_autosuspend()` helper functions +instead of the non-autosuspend counterparts:: + + Instead of: pm_runtime_suspend use: pm_runtime_autosuspend; + Instead of: pm_schedule_suspend use: pm_request_autosuspend; + Instead of: pm_runtime_put use: pm_runtime_put_autosuspend; + Instead of: pm_runtime_put_sync use: pm_runtime_put_sync_autosuspend. + +Drivers may also continue to use the non-autosuspend helper functions; they +will behave normally, which means sometimes taking the autosuspend delay into +account (see pm_runtime_idle). + +Under some circumstances a driver or subsystem may want to prevent a device +from autosuspending immediately, even though the usage counter is zero and the +autosuspend delay time has expired. If the ->runtime_suspend() callback +returns -EAGAIN or -EBUSY, and if the next autosuspend delay expiration time is +in the future (as it normally would be if the callback invoked +pm_runtime_mark_last_busy()), the PM core will automatically reschedule the +autosuspend. The ->runtime_suspend() callback can't do this rescheduling +itself because no suspend requests of any kind are accepted while the device is +suspending (i.e., while the callback is running). + +The implementation is well suited for asynchronous use in interrupt contexts. +However such use inevitably involves races, because the PM core can't +synchronize ->runtime_suspend() callbacks with the arrival of I/O requests. +This synchronization must be handled by the driver, using its private lock. +Here is a schematic pseudo-code example:: + + foo_read_or_write(struct foo_priv *foo, void *data) + { + lock(&foo->private_lock); + add_request_to_io_queue(foo, data); + if (foo->num_pending_requests++ == 0) + pm_runtime_get(&foo->dev); + if (!foo->is_suspended) + foo_process_next_request(foo); + unlock(&foo->private_lock); + } + + foo_io_completion(struct foo_priv *foo, void *req) + { + lock(&foo->private_lock); + if (--foo->num_pending_requests == 0) { + pm_runtime_mark_last_busy(&foo->dev); + pm_runtime_put_autosuspend(&foo->dev); + } else { + foo_process_next_request(foo); + } + unlock(&foo->private_lock); + /* Send req result back to the user ... */ + } + + int foo_runtime_suspend(struct device *dev) + { + struct foo_priv foo = container_of(dev, ...); + int ret = 0; + + lock(&foo->private_lock); + if (foo->num_pending_requests > 0) { + ret = -EBUSY; + } else { + /* ... suspend the device ... */ + foo->is_suspended = 1; + } + unlock(&foo->private_lock); + return ret; + } + + int foo_runtime_resume(struct device *dev) + { + struct foo_priv foo = container_of(dev, ...); + + lock(&foo->private_lock); + /* ... resume the device ... */ + foo->is_suspended = 0; + pm_runtime_mark_last_busy(&foo->dev); + if (foo->num_pending_requests > 0) + foo_process_next_request(foo); + unlock(&foo->private_lock); + return 0; + } + +The important point is that after foo_io_completion() asks for an autosuspend, +the foo_runtime_suspend() callback may race with foo_read_or_write(). +Therefore foo_runtime_suspend() has to check whether there are any pending I/O +requests (while holding the private lock) before allowing the suspend to +proceed. + +In addition, the power.autosuspend_delay field can be changed by user space at +any time. If a driver cares about this, it can call +pm_runtime_autosuspend_expiration() from within the ->runtime_suspend() +callback while holding its private lock. If the function returns a nonzero +value then the delay has not yet expired and the callback should return +-EAGAIN. diff --git a/Documentation/power/runtime_pm.txt b/Documentation/power/runtime_pm.txt deleted file mode 100644 index 937e33c46211..000000000000 --- a/Documentation/power/runtime_pm.txt +++ /dev/null @@ -1,928 +0,0 @@ -Runtime Power Management Framework for I/O Devices - -(C) 2009-2011 Rafael J. Wysocki , Novell Inc. -(C) 2010 Alan Stern -(C) 2014 Intel Corp., Rafael J. Wysocki - -1. Introduction - -Support for runtime power management (runtime PM) of I/O devices is provided -at the power management core (PM core) level by means of: - -* The power management workqueue pm_wq in which bus types and device drivers can - put their PM-related work items. It is strongly recommended that pm_wq be - used for queuing all work items related to runtime PM, because this allows - them to be synchronized with system-wide power transitions (suspend to RAM, - hibernation and resume from system sleep states). pm_wq is declared in - include/linux/pm_runtime.h and defined in kernel/power/main.c. - -* A number of runtime PM fields in the 'power' member of 'struct device' (which - is of the type 'struct dev_pm_info', defined in include/linux/pm.h) that can - be used for synchronizing runtime PM operations with one another. - -* Three device runtime PM callbacks in 'struct dev_pm_ops' (defined in - include/linux/pm.h). - -* A set of helper functions defined in drivers/base/power/runtime.c that can be - used for carrying out runtime PM operations in such a way that the - synchronization between them is taken care of by the PM core. Bus types and - device drivers are encouraged to use these functions. - -The runtime PM callbacks present in 'struct dev_pm_ops', the device runtime PM -fields of 'struct dev_pm_info' and the core helper functions provided for -runtime PM are described below. - -2. Device Runtime PM Callbacks - -There are three device runtime PM callbacks defined in 'struct dev_pm_ops': - -struct dev_pm_ops { - ... - int (*runtime_suspend)(struct device *dev); - int (*runtime_resume)(struct device *dev); - int (*runtime_idle)(struct device *dev); - ... -}; - -The ->runtime_suspend(), ->runtime_resume() and ->runtime_idle() callbacks -are executed by the PM core for the device's subsystem that may be either of -the following: - - 1. PM domain of the device, if the device's PM domain object, dev->pm_domain, - is present. - - 2. Device type of the device, if both dev->type and dev->type->pm are present. - - 3. Device class of the device, if both dev->class and dev->class->pm are - present. - - 4. Bus type of the device, if both dev->bus and dev->bus->pm are present. - -If the subsystem chosen by applying the above rules doesn't provide the relevant -callback, the PM core will invoke the corresponding driver callback stored in -dev->driver->pm directly (if present). - -The PM core always checks which callback to use in the order given above, so the -priority order of callbacks from high to low is: PM domain, device type, class -and bus type. Moreover, the high-priority one will always take precedence over -a low-priority one. The PM domain, bus type, device type and class callbacks -are referred to as subsystem-level callbacks in what follows. - -By default, the callbacks are always invoked in process context with interrupts -enabled. However, the pm_runtime_irq_safe() helper function can be used to tell -the PM core that it is safe to run the ->runtime_suspend(), ->runtime_resume() -and ->runtime_idle() callbacks for the given device in atomic context with -interrupts disabled. This implies that the callback routines in question must -not block or sleep, but it also means that the synchronous helper functions -listed at the end of Section 4 may be used for that device within an interrupt -handler or generally in an atomic context. - -The subsystem-level suspend callback, if present, is _entirely_ _responsible_ -for handling the suspend of the device as appropriate, which may, but need not -include executing the device driver's own ->runtime_suspend() callback (from the -PM core's point of view it is not necessary to implement a ->runtime_suspend() -callback in a device driver as long as the subsystem-level suspend callback -knows what to do to handle the device). - - * Once the subsystem-level suspend callback (or the driver suspend callback, - if invoked directly) has completed successfully for the given device, the PM - core regards the device as suspended, which need not mean that it has been - put into a low power state. It is supposed to mean, however, that the - device will not process data and will not communicate with the CPU(s) and - RAM until the appropriate resume callback is executed for it. The runtime - PM status of a device after successful execution of the suspend callback is - 'suspended'. - - * If the suspend callback returns -EBUSY or -EAGAIN, the device's runtime PM - status remains 'active', which means that the device _must_ be fully - operational afterwards. - - * If the suspend callback returns an error code different from -EBUSY and - -EAGAIN, the PM core regards this as a fatal error and will refuse to run - the helper functions described in Section 4 for the device until its status - is directly set to either 'active', or 'suspended' (the PM core provides - special helper functions for this purpose). - -In particular, if the driver requires remote wakeup capability (i.e. hardware -mechanism allowing the device to request a change of its power state, such as -PCI PME) for proper functioning and device_can_wakeup() returns 'false' for the -device, then ->runtime_suspend() should return -EBUSY. On the other hand, if -device_can_wakeup() returns 'true' for the device and the device is put into a -low-power state during the execution of the suspend callback, it is expected -that remote wakeup will be enabled for the device. Generally, remote wakeup -should be enabled for all input devices put into low-power states at run time. - -The subsystem-level resume callback, if present, is _entirely_ _responsible_ for -handling the resume of the device as appropriate, which may, but need not -include executing the device driver's own ->runtime_resume() callback (from the -PM core's point of view it is not necessary to implement a ->runtime_resume() -callback in a device driver as long as the subsystem-level resume callback knows -what to do to handle the device). - - * Once the subsystem-level resume callback (or the driver resume callback, if - invoked directly) has completed successfully, the PM core regards the device - as fully operational, which means that the device _must_ be able to complete - I/O operations as needed. The runtime PM status of the device is then - 'active'. - - * If the resume callback returns an error code, the PM core regards this as a - fatal error and will refuse to run the helper functions described in Section - 4 for the device, until its status is directly set to either 'active', or - 'suspended' (by means of special helper functions provided by the PM core - for this purpose). - -The idle callback (a subsystem-level one, if present, or the driver one) is -executed by the PM core whenever the device appears to be idle, which is -indicated to the PM core by two counters, the device's usage counter and the -counter of 'active' children of the device. - - * If any of these counters is decreased using a helper function provided by - the PM core and it turns out to be equal to zero, the other counter is - checked. If that counter also is equal to zero, the PM core executes the - idle callback with the device as its argument. - -The action performed by the idle callback is totally dependent on the subsystem -(or driver) in question, but the expected and recommended action is to check -if the device can be suspended (i.e. if all of the conditions necessary for -suspending the device are satisfied) and to queue up a suspend request for the -device in that case. If there is no idle callback, or if the callback returns -0, then the PM core will attempt to carry out a runtime suspend of the device, -also respecting devices configured for autosuspend. In essence this means a -call to pm_runtime_autosuspend() (do note that drivers needs to update the -device last busy mark, pm_runtime_mark_last_busy(), to control the delay under -this circumstance). To prevent this (for example, if the callback routine has -started a delayed suspend), the routine must return a non-zero value. Negative -error return codes are ignored by the PM core. - -The helper functions provided by the PM core, described in Section 4, guarantee -that the following constraints are met with respect to runtime PM callbacks for -one device: - -(1) The callbacks are mutually exclusive (e.g. it is forbidden to execute - ->runtime_suspend() in parallel with ->runtime_resume() or with another - instance of ->runtime_suspend() for the same device) with the exception that - ->runtime_suspend() or ->runtime_resume() can be executed in parallel with - ->runtime_idle() (although ->runtime_idle() will not be started while any - of the other callbacks is being executed for the same device). - -(2) ->runtime_idle() and ->runtime_suspend() can only be executed for 'active' - devices (i.e. the PM core will only execute ->runtime_idle() or - ->runtime_suspend() for the devices the runtime PM status of which is - 'active'). - -(3) ->runtime_idle() and ->runtime_suspend() can only be executed for a device - the usage counter of which is equal to zero _and_ either the counter of - 'active' children of which is equal to zero, or the 'power.ignore_children' - flag of which is set. - -(4) ->runtime_resume() can only be executed for 'suspended' devices (i.e. the - PM core will only execute ->runtime_resume() for the devices the runtime - PM status of which is 'suspended'). - -Additionally, the helper functions provided by the PM core obey the following -rules: - - * If ->runtime_suspend() is about to be executed or there's a pending request - to execute it, ->runtime_idle() will not be executed for the same device. - - * A request to execute or to schedule the execution of ->runtime_suspend() - will cancel any pending requests to execute ->runtime_idle() for the same - device. - - * If ->runtime_resume() is about to be executed or there's a pending request - to execute it, the other callbacks will not be executed for the same device. - - * A request to execute ->runtime_resume() will cancel any pending or - scheduled requests to execute the other callbacks for the same device, - except for scheduled autosuspends. - -3.

Runtime PM Initialization, Device Probing and Removal - -Initially, the runtime PM is disabled for all devices, which means that the -majority of the runtime PM helper functions described in Section 4 will return --EAGAIN until pm_runtime_enable() is called for the device. - -In addition to that, the initial runtime PM status of all devices is -'suspended', but it need not reflect the actual physical state of the device. -Thus, if the device is initially active (i.e. it is able to process I/O), its -runtime PM status must be changed to 'active', with the help of -pm_runtime_set_active(), before pm_runtime_enable() is called for the device. - -However, if the device has a parent and the parent's runtime PM is enabled, -calling pm_runtime_set_active() for the device will affect the parent, unless -the parent's 'power.ignore_children' flag is set. Namely, in that case the -parent won't be able to suspend at run time, using the PM core's helper -functions, as long as the child's status is 'active', even if the child's -runtime PM is still disabled (i.e. pm_runtime_enable() hasn't been called for -the child yet or pm_runtime_disable() has been called for it). For this reason, -once pm_runtime_set_active() has been called for the device, pm_runtime_enable() -should be called for it too as soon as reasonably possible or its runtime PM -status should be changed back to 'suspended' with the help of -pm_runtime_set_suspended(). - -If the default initial runtime PM status of the device (i.e. 'suspended') -reflects the actual state of the device, its bus type's or its driver's -->probe() callback will likely need to wake it up using one of the PM core's -helper functions described in Section 4. In that case, pm_runtime_resume() -should be used. Of course, for this purpose the device's runtime PM has to be -enabled earlier by calling pm_runtime_enable(). - -Note, if the device may execute pm_runtime calls during the probe (such as -if it is registers with a subsystem that may call back in) then the -pm_runtime_get_sync() call paired with a pm_runtime_put() call will be -appropriate to ensure that the device is not put back to sleep during the -probe. This can happen with systems such as the network device layer. - -It may be desirable to suspend the device once ->probe() has finished. -Therefore the driver core uses the asynchronous pm_request_idle() to submit a -request to execute the subsystem-level idle callback for the device at that -time. A driver that makes use of the runtime autosuspend feature, may want to -update the last busy mark before returning from ->probe(). - -Moreover, the driver core prevents runtime PM callbacks from racing with the bus -notifier callback in __device_release_driver(), which is necessary, because the -notifier is used by some subsystems to carry out operations affecting the -runtime PM functionality. It does so by calling pm_runtime_get_sync() before -driver_sysfs_remove() and the BUS_NOTIFY_UNBIND_DRIVER notifications. This -resumes the device if it's in the suspended state and prevents it from -being suspended again while those routines are being executed. - -To allow bus types and drivers to put devices into the suspended state by -calling pm_runtime_suspend() from their ->remove() routines, the driver core -executes pm_runtime_put_sync() after running the BUS_NOTIFY_UNBIND_DRIVER -notifications in __device_release_driver(). This requires bus types and -drivers to make their ->remove() callbacks avoid races with runtime PM directly, -but also it allows of more flexibility in the handling of devices during the -removal of their drivers. - -Drivers in ->remove() callback should undo the runtime PM changes done -in ->probe(). Usually this means calling pm_runtime_disable(), -pm_runtime_dont_use_autosuspend() etc. - -The user space can effectively disallow the driver of the device to power manage -it at run time by changing the value of its /sys/devices/.../power/control -attribute to "on", which causes pm_runtime_forbid() to be called. In principle, -this mechanism may also be used by the driver to effectively turn off the -runtime power management of the device until the user space turns it on. -Namely, during the initialization the driver can make sure that the runtime PM -status of the device is 'active' and call pm_runtime_forbid(). It should be -noted, however, that if the user space has already intentionally changed the -value of /sys/devices/.../power/control to "auto" to allow the driver to power -manage the device at run time, the driver may confuse it by using -pm_runtime_forbid() this way. - -6. Runtime PM and System Sleep - -Runtime PM and system sleep (i.e., system suspend and hibernation, also known -as suspend-to-RAM and suspend-to-disk) interact with each other in a couple of -ways. If a device is active when a system sleep starts, everything is -straightforward. But what should happen if the device is already suspended? - -The device may have different wake-up settings for runtime PM and system sleep. -For example, remote wake-up may be enabled for runtime suspend but disallowed -for system sleep (device_may_wakeup(dev) returns 'false'). When this happens, -the subsystem-level system suspend callback is responsible for changing the -device's wake-up setting (it may leave that to the device driver's system -suspend routine). It may be necessary to resume the device and suspend it again -in order to do so. The same is true if the driver uses different power levels -or other settings for runtime suspend and system sleep. - -During system resume, the simplest approach is to bring all devices back to full -power, even if they had been suspended before the system suspend began. There -are several reasons for this, including: - - * The device might need to switch power levels, wake-up settings, etc. - - * Remote wake-up events might have been lost by the firmware. - - * The device's children may need the device to be at full power in order - to resume themselves. - - * The driver's idea of the device state may not agree with the device's - physical state. This can happen during resume from hibernation. - - * The device might need to be reset. - - * Even though the device was suspended, if its usage counter was > 0 then most - likely it would need a runtime resume in the near future anyway. - -If the device had been suspended before the system suspend began and it's -brought back to full power during resume, then its runtime PM status will have -to be updated to reflect the actual post-system sleep status. The way to do -this is: - - pm_runtime_disable(dev); - pm_runtime_set_active(dev); - pm_runtime_enable(dev); - -The PM core always increments the runtime usage counter before calling the -->suspend() callback and decrements it after calling the ->resume() callback. -Hence disabling runtime PM temporarily like this will not cause any runtime -suspend attempts to be permanently lost. If the usage count goes to zero -following the return of the ->resume() callback, the ->runtime_idle() callback -will be invoked as usual. - -On some systems, however, system sleep is not entered through a global firmware -or hardware operation. Instead, all hardware components are put into low-power -states directly by the kernel in a coordinated way. Then, the system sleep -state effectively follows from the states the hardware components end up in -and the system is woken up from that state by a hardware interrupt or a similar -mechanism entirely under the kernel's control. As a result, the kernel never -gives control away and the states of all devices during resume are precisely -known to it. If that is the case and none of the situations listed above takes -place (in particular, if the system is not waking up from hibernation), it may -be more efficient to leave the devices that had been suspended before the system -suspend began in the suspended state. - -To this end, the PM core provides a mechanism allowing some coordination between -different levels of device hierarchy. Namely, if a system suspend .prepare() -callback returns a positive number for a device, that indicates to the PM core -that the device appears to be runtime-suspended and its state is fine, so it -may be left in runtime suspend provided that all of its descendants are also -left in runtime suspend. If that happens, the PM core will not execute any -system suspend and resume callbacks for all of those devices, except for the -complete callback, which is then entirely responsible for handling the device -as appropriate. This only applies to system suspend transitions that are not -related to hibernation (see Documentation/driver-api/pm/devices.rst for more -information). - -The PM core does its best to reduce the probability of race conditions between -the runtime PM and system suspend/resume (and hibernation) callbacks by carrying -out the following operations: - - * During system suspend pm_runtime_get_noresume() is called for every device - right before executing the subsystem-level .prepare() callback for it and - pm_runtime_barrier() is called for every device right before executing the - subsystem-level .suspend() callback for it. In addition to that the PM core - calls __pm_runtime_disable() with 'false' as the second argument for every - device right before executing the subsystem-level .suspend_late() callback - for it. - - * During system resume pm_runtime_enable() and pm_runtime_put() are called for - every device right after executing the subsystem-level .resume_early() - callback and right after executing the subsystem-level .complete() callback - for it, respectively. - -7. Generic subsystem callbacks - -Subsystems may wish to conserve code space by using the set of generic power -management callbacks provided by the PM core, defined in -driver/base/power/generic_ops.c: - - int pm_generic_runtime_suspend(struct device *dev); - - invoke the ->runtime_suspend() callback provided by the driver of this - device and return its result, or return 0 if not defined - - int pm_generic_runtime_resume(struct device *dev); - - invoke the ->runtime_resume() callback provided by the driver of this - device and return its result, or return 0 if not defined - - int pm_generic_suspend(struct device *dev); - - if the device has not been suspended at run time, invoke the ->suspend() - callback provided by its driver and return its result, or return 0 if not - defined - - int pm_generic_suspend_noirq(struct device *dev); - - if pm_runtime_suspended(dev) returns "false", invoke the ->suspend_noirq() - callback provided by the device's driver and return its result, or return - 0 if not defined - - int pm_generic_resume(struct device *dev); - - invoke the ->resume() callback provided by the driver of this device and, - if successful, change the device's runtime PM status to 'active' - - int pm_generic_resume_noirq(struct device *dev); - - invoke the ->resume_noirq() callback provided by the driver of this device - - int pm_generic_freeze(struct device *dev); - - if the device has not been suspended at run time, invoke the ->freeze() - callback provided by its driver and return its result, or return 0 if not - defined - - int pm_generic_freeze_noirq(struct device *dev); - - if pm_runtime_suspended(dev) returns "false", invoke the ->freeze_noirq() - callback provided by the device's driver and return its result, or return - 0 if not defined - - int pm_generic_thaw(struct device *dev); - - if the device has not been suspended at run time, invoke the ->thaw() - callback provided by its driver and return its result, or return 0 if not - defined - - int pm_generic_thaw_noirq(struct device *dev); - - if pm_runtime_suspended(dev) returns "false", invoke the ->thaw_noirq() - callback provided by the device's driver and return its result, or return - 0 if not defined - - int pm_generic_poweroff(struct device *dev); - - if the device has not been suspended at run time, invoke the ->poweroff() - callback provided by its driver and return its result, or return 0 if not - defined - - int pm_generic_poweroff_noirq(struct device *dev); - - if pm_runtime_suspended(dev) returns "false", run the ->poweroff_noirq() - callback provided by the device's driver and return its result, or return - 0 if not defined - - int pm_generic_restore(struct device *dev); - - invoke the ->restore() callback provided by the driver of this device and, - if successful, change the device's runtime PM status to 'active' - - int pm_generic_restore_noirq(struct device *dev); - - invoke the ->restore_noirq() callback provided by the device's driver - -These functions are the defaults used by the PM core, if a subsystem doesn't -provide its own callbacks for ->runtime_idle(), ->runtime_suspend(), -->runtime_resume(), ->suspend(), ->suspend_noirq(), ->resume(), -->resume_noirq(), ->freeze(), ->freeze_noirq(), ->thaw(), ->thaw_noirq(), -->poweroff(), ->poweroff_noirq(), ->restore(), ->restore_noirq() in the -subsystem-level dev_pm_ops structure. - -Device drivers that wish to use the same function as a system suspend, freeze, -poweroff and runtime suspend callback, and similarly for system resume, thaw, -restore, and runtime resume, can achieve this with the help of the -UNIVERSAL_DEV_PM_OPS macro defined in include/linux/pm.h (possibly setting its -last argument to NULL). - -8. "No-Callback" Devices - -Some "devices" are only logical sub-devices of their parent and cannot be -power-managed on their own. (The prototype example is a USB interface. Entire -USB devices can go into low-power mode or send wake-up requests, but neither is -possible for individual interfaces.) The drivers for these devices have no -need of runtime PM callbacks; if the callbacks did exist, ->runtime_suspend() -and ->runtime_resume() would always return 0 without doing anything else and -->runtime_idle() would always call pm_runtime_suspend(). - -Subsystems can tell the PM core about these devices by calling -pm_runtime_no_callbacks(). This should be done after the device structure is -initialized and before it is registered (although after device registration is -also okay). The routine will set the device's power.no_callbacks flag and -prevent the non-debugging runtime PM sysfs attributes from being created. - -When power.no_callbacks is set, the PM core will not invoke the -->runtime_idle(), ->runtime_suspend(), or ->runtime_resume() callbacks. -Instead it will assume that suspends and resumes always succeed and that idle -devices should be suspended. - -As a consequence, the PM core will never directly inform the device's subsystem -or driver about runtime power changes. Instead, the driver for the device's -parent must take responsibility for telling the device's driver when the -parent's power state changes. - -9. Autosuspend, or automatically-delayed suspends - -Changing a device's power state isn't free; it requires both time and energy. -A device should be put in a low-power state only when there's some reason to -think it will remain in that state for a substantial time. A common heuristic -says that a device which hasn't been used for a while is liable to remain -unused; following this advice, drivers should not allow devices to be suspended -at runtime until they have been inactive for some minimum period. Even when -the heuristic ends up being non-optimal, it will still prevent devices from -"bouncing" too rapidly between low-power and full-power states. - -The term "autosuspend" is an historical remnant. It doesn't mean that the -device is automatically suspended (the subsystem or driver still has to call -the appropriate PM routines); rather it means that runtime suspends will -automatically be delayed until the desired period of inactivity has elapsed. - -Inactivity is determined based on the power.last_busy field. Drivers should -call pm_runtime_mark_last_busy() to update this field after carrying out I/O, -typically just before calling pm_runtime_put_autosuspend(). The desired length -of the inactivity period is a matter of policy. Subsystems can set this length -initially by calling pm_runtime_set_autosuspend_delay(), but after device -registration the length should be controlled by user space, using the -/sys/devices/.../power/autosuspend_delay_ms attribute. - -In order to use autosuspend, subsystems or drivers must call -pm_runtime_use_autosuspend() (preferably before registering the device), and -thereafter they should use the various *_autosuspend() helper functions instead -of the non-autosuspend counterparts: - - Instead of: pm_runtime_suspend use: pm_runtime_autosuspend; - Instead of: pm_schedule_suspend use: pm_request_autosuspend; - Instead of: pm_runtime_put use: pm_runtime_put_autosuspend; - Instead of: pm_runtime_put_sync use: pm_runtime_put_sync_autosuspend. - -Drivers may also continue to use the non-autosuspend helper functions; they -will behave normally, which means sometimes taking the autosuspend delay into -account (see pm_runtime_idle). - -Under some circumstances a driver or subsystem may want to prevent a device -from autosuspending immediately, even though the usage counter is zero and the -autosuspend delay time has expired. If the ->runtime_suspend() callback -returns -EAGAIN or -EBUSY, and if the next autosuspend delay expiration time is -in the future (as it normally would be if the callback invoked -pm_runtime_mark_last_busy()), the PM core will automatically reschedule the -autosuspend. The ->runtime_suspend() callback can't do this rescheduling -itself because no suspend requests of any kind are accepted while the device is -suspending (i.e., while the callback is running). - -The implementation is well suited for asynchronous use in interrupt contexts. -However such use inevitably involves races, because the PM core can't -synchronize ->runtime_suspend() callbacks with the arrival of I/O requests. -This synchronization must be handled by the driver, using its private lock. -Here is a schematic pseudo-code example: - - foo_read_or_write(struct foo_priv *foo, void *data) - { - lock(&foo->private_lock); - add_request_to_io_queue(foo, data); - if (foo->num_pending_requests++ == 0) - pm_runtime_get(&foo->dev); - if (!foo->is_suspended) - foo_process_next_request(foo); - unlock(&foo->private_lock); - } - - foo_io_completion(struct foo_priv *foo, void *req) - { - lock(&foo->private_lock); - if (--foo->num_pending_requests == 0) { - pm_runtime_mark_last_busy(&foo->dev); - pm_runtime_put_autosuspend(&foo->dev); - } else { - foo_process_next_request(foo); - } - unlock(&foo->private_lock); - /* Send req result back to the user ... */ - } - - int foo_runtime_suspend(struct device *dev) - { - struct foo_priv foo = container_of(dev, ...); - int ret = 0; - - lock(&foo->private_lock); - if (foo->num_pending_requests > 0) { - ret = -EBUSY; - } else { - /* ... suspend the device ... */ - foo->is_suspended = 1; - } - unlock(&foo->private_lock); - return ret; - } - - int foo_runtime_resume(struct device *dev) - { - struct foo_priv foo = container_of(dev, ...); - - lock(&foo->private_lock); - /* ... resume the device ... */ - foo->is_suspended = 0; - pm_runtime_mark_last_busy(&foo->dev); - if (foo->num_pending_requests > 0) - foo_process_next_request(foo); - unlock(&foo->private_lock); - return 0; - } - -The important point is that after foo_io_completion() asks for an autosuspend, -the foo_runtime_suspend() callback may race with foo_read_or_write(). -Therefore foo_runtime_suspend() has to check whether there are any pending I/O -requests (while holding the private lock) before allowing the suspend to -proceed. - -In addition, the power.autosuspend_delay field can be changed by user space at -any time. If a driver cares about this, it can call -pm_runtime_autosuspend_expiration() from within the ->runtime_suspend() -callback while holding its private lock. If the function returns a nonzero -value then the delay has not yet expired and the callback should return --EAGAIN. diff --git a/Documentation/power/s2ram.rst b/Documentation/power/s2ram.rst new file mode 100644 index 000000000000..d739aa7c742c --- /dev/null +++ b/Documentation/power/s2ram.rst @@ -0,0 +1,87 @@ +======================== +How to get s2ram working +======================== + +2006 Linus Torvalds +2006 Pavel Machek + +1) Check suspend.sf.net, program s2ram there has long whitelist of + "known ok" machines, along with tricks to use on each one. + +2) If that does not help, try reading tricks.txt and + video.txt.

The function doing that is resume_device_irqs(). + + +The IRQF_NO_SUSPEND Flag +------------------------ + +There are interrupts that can legitimately trigger during the entire system +suspend-resume cycle, including the "noirq" phases of suspending and resuming +devices as well as during the time when nonboot CPUs are taken offline and +brought back online. That applies to timer interrupts in the first place, +but also to IPIs and to some other special-purpose interrupts. + +The IRQF_NO_SUSPEND flag is used to indicate that to the IRQ subsystem when +requesting a special-purpose interrupt. It causes suspend_device_irqs() to +leave the corresponding IRQ enabled so as to allow the interrupt to work as +expected during the suspend-resume cycle, but does not guarantee that the +interrupt will wake the system from a suspended state -- for such cases it is +necessary to use enable_irq_wake(). + +Note that the IRQF_NO_SUSPEND flag affects the entire IRQ and not just one +user of it.

For this reason, using IRQF_NO_SUSPEND and IRQF_SHARED at the +same time should be avoided. + + +System Wakeup Interrupts, enable_irq_wake() and disable_irq_wake() +------------------------------------------------------------------ + +System wakeup interrupts generally need to be configured to wake up the system +from sleep states, especially if they are used for different purposes (e.g. as +I/O interrupts) in the working state. + +That may involve turning on a special signal handling logic within the platform +(such as an SoC) so that signals from a given line are routed in a different way +during system sleep so as to trigger a system wakeup when needed. For example, +the platform may include a dedicated interrupt controller used specifically for +handling system wakeup events. Then, if a given interrupt line is supposed to +wake up the system from sleep sates, the corresponding input of that interrupt +controller needs to be enabled to receive signals from the line in question. +After wakeup, it generally is better to disable that input to prevent the +dedicated controller from triggering interrupts unnecessarily. + +The IRQ subsystem provides two helper functions to be used by device drivers for +those purposes. Namely, enable_irq_wake() turns on the platform's logic for +handling the given IRQ as a system wakeup interrupt line and disable_irq_wake() +turns that logic off. + +Calling enable_irq_wake() causes suspend_device_irqs() to treat the given IRQ +in a special way. Namely, the IRQ remains enabled, by on the first interrupt +it will be disabled, marked as pending and "suspended" so that it will be +re-enabled by resume_device_irqs() during the subsequent system resume. Also +the PM core is notified about the event which causes the system suspend in +progress to be aborted (that doesn't have to happen immediately, but at one +of the points where the suspend thread looks for pending wakeup events). + +This way every interrupt from a wakeup interrupt source will either cause the +system suspend currently in progress to be aborted or wake up the system if +already suspended. However, after suspend_device_irqs() interrupt handlers are +not executed for system wakeup IRQs. They are only executed for IRQF_NO_SUSPEND +IRQs at that time, but those IRQs should not be configured for system wakeup +using enable_irq_wake(). + + +Interrupts and Suspend-to-Idle +------------------------------ + +Suspend-to-idle (also known as the "freeze" sleep state) is a relatively new +system sleep state that works by idling all of the processors and waiting for +interrupts right after the "noirq" phase of suspending devices. + +Of course, this means that all of the interrupts with the IRQF_NO_SUSPEND flag +set will bring CPUs out of idle while in that state, but they will not cause the +IRQ subsystem to trigger a system wakeup. + +System wakeup interrupts, in turn, will trigger wakeup from suspend-to-idle in +analogy with what they do in the full system suspend case. The only difference +is that the wakeup from suspend-to-idle is signaled using the usual working +state interrupt delivery mechanisms and doesn't require the platform to use +any special interrupt handling logic for it to work. + + +IRQF_NO_SUSPEND and enable_irq_wake() +------------------------------------- + +There are very few valid reasons to use both enable_irq_wake() and the +IRQF_NO_SUSPEND flag on the same IRQ, and it is never valid to use both for the +same device. + +First of all, if the IRQ is not shared, the rules for handling IRQF_NO_SUSPEND +interrupts (interrupt handlers are invoked after suspend_device_irqs()) are +directly at odds with the rules for handling system wakeup interrupts (interrupt +handlers are not invoked after suspend_device_irqs()). + +Second, both enable_irq_wake() and IRQF_NO_SUSPEND apply to entire IRQs and not +to individual interrupt handlers, so sharing an IRQ between a system wakeup +interrupt source and an IRQF_NO_SUSPEND interrupt source does not generally +make sense. + +In rare cases an IRQ can be shared between a wakeup device driver and an +IRQF_NO_SUSPEND user. In order for this to be safe, the wakeup device driver +must be able to discern spurious IRQs from genuine wakeup events (signalling +the latter to the core with pm_system_wakeup()), must use enable_irq_wake() to +ensure that the IRQ will function as a wakeup source, and must request the IRQ +with IRQF_COND_SUSPEND to tell the core that it meets these requirements. If +these requirements are not met, it is not valid to use IRQF_COND_SUSPEND. diff --git a/Documentation/power/suspend-and-interrupts.txt b/Documentation/power/suspend-and-interrupts.txt deleted file mode 100644 index 8afb29a8604a..000000000000 --- a/Documentation/power/suspend-and-interrupts.txt +++ /dev/null @@ -1,135 +0,0 @@ -System Suspend and Device Interrupts - -Copyright (C) 2014 Intel Corp. -Author: Rafael J.

Namely, enable_irq_wake() turns on the platform's logic for -handling the given IRQ as a system wakeup interrupt line and disable_irq_wake() -turns that logic off. - -Calling enable_irq_wake() causes suspend_device_irqs() to treat the given IRQ -in a special way. Namely, the IRQ remains enabled, by on the first interrupt -it will be disabled, marked as pending and "suspended" so that it will be -re-enabled by resume_device_irqs() during the subsequent system resume. Also -the PM core is notified about the event which causes the system suspend in -progress to be aborted (that doesn't have to happen immediately, but at one -of the points where the suspend thread looks for pending wakeup events). - -This way every interrupt from a wakeup interrupt source will either cause the -system suspend currently in progress to be aborted or wake up the system if -already suspended. However, after suspend_device_irqs() interrupt handlers are -not executed for system wakeup IRQs. They are only executed for IRQF_NO_SUSPEND -IRQs at that time, but those IRQs should not be configured for system wakeup -using enable_irq_wake(). - - -Interrupts and Suspend-to-Idle ------------------------------- - -Suspend-to-idle (also known as the "freeze" sleep state) is a relatively new -system sleep state that works by idling all of the processors and waiting for -interrupts right after the "noirq" phase of suspending devices. - -Of course, this means that all of the interrupts with the IRQF_NO_SUSPEND flag -set will bring CPUs out of idle while in that state, but they will not cause the -IRQ subsystem to trigger a system wakeup. - -System wakeup interrupts, in turn, will trigger wakeup from suspend-to-idle in -analogy with what they do in the full system suspend case. The only difference -is that the wakeup from suspend-to-idle is signaled using the usual working -state interrupt delivery mechanisms and doesn't require the platform to use -any special interrupt handling logic for it to work. - - -IRQF_NO_SUSPEND and enable_irq_wake() -------------------------------------- - -There are very few valid reasons to use both enable_irq_wake() and the -IRQF_NO_SUSPEND flag on the same IRQ, and it is never valid to use both for the -same device. - -First of all, if the IRQ is not shared, the rules for handling IRQF_NO_SUSPEND -interrupts (interrupt handlers are invoked after suspend_device_irqs()) are -directly at odds with the rules for handling system wakeup interrupts (interrupt -handlers are not invoked after suspend_device_irqs()). - -Second, both enable_irq_wake() and IRQF_NO_SUSPEND apply to entire IRQs and not -to individual interrupt handlers, so sharing an IRQ between a system wakeup -interrupt source and an IRQF_NO_SUSPEND interrupt source does not generally -make sense. - -In rare cases an IRQ can be shared between a wakeup device driver and an -IRQF_NO_SUSPEND user. In order for this to be safe, the wakeup device driver -must be able to discern spurious IRQs from genuine wakeup events (signalling -the latter to the core with pm_system_wakeup()), must use enable_irq_wake() to -ensure that the IRQ will function as a wakeup source, and must request the IRQ -with IRQF_COND_SUSPEND to tell the core that it meets these requirements. If -these requirements are not met, it is not valid to use IRQF_COND_SUSPEND. diff --git a/Documentation/power/swsusp-and-swap-files.rst b/Documentation/power/swsusp-and-swap-files.rst new file mode 100644 index 000000000000..a33a2919dbe4 --- /dev/null +++ b/Documentation/power/swsusp-and-swap-files.rst @@ -0,0 +1,63 @@ +=============================================== +Using swap files with software suspend (swsusp) +=============================================== + + (C) 2006 Rafael J.

It +saves the state of the machine to a filesystem or to a partition and switches +to standby mode. Later resuming the machine the saved state is loaded back to +ram and the machine can continue its work. It has two real benefits. First we +save ourselves the time machine goes down and later boots up, energy costs +are real high when running from batteries. The other gain is that we don't have +to interrupt our programs so processes that are calculating something for a long +time shouldn't need to be written interruptible. + +swsusp saves the state of the machine into active swaps and then reboots or +powerdowns. You must explicitly specify the swap partition to resume from with +`resume=` kernel option. If signature is found it loads and restores saved +state. If the option `noresume` is specified as a boot parameter, it skips +the resuming. If the option `hibernate=nocompress` is specified as a boot +parameter, it saves hibernation image without compression. + +In the meantime while the system is suspended you should not add/remove any +of the hardware, write to the filesystems, etc. + +Sleep states summary +==================== + +There are three different interfaces you can use, /proc/acpi should +work like this: + +In a really perfect world:: + + echo 1 > /proc/acpi/sleep # for standby + echo 2 > /proc/acpi/sleep # for suspend to ram + echo 3 > /proc/acpi/sleep # for suspend to ram, but with more power conservative + echo 4 > /proc/acpi/sleep # for suspend to disk + echo 5 > /proc/acpi/sleep # for shutdown unfriendly the system + +and perhaps:: + + echo 4b > /proc/acpi/sleep # for suspend to disk via s4bios + +Frequently Asked Questions +========================== + +Q: + well, suspending a server is IMHO a really stupid thing, + but... (Diego Zuccato): + +A: + You bought new UPS for your server. How do you install it without + bringing machine down? Suspend to disk, rearrange power cables, + resume. + + You have your server on UPS. Power died, and UPS is indicating 30 + seconds to failure. What do you do? Suspend to disk. + + +Q: + Maybe I'm missing something, but why don't the regular I/O paths work? + +A: + We do use the regular I/O paths. However we cannot restore the data + to its original location as we load it. That would create an + inconsistent kernel state which would certainly result in an oops. + Instead, we load the image into unused memory and then atomically copy + it back to it original location. This implies, of course, a maximum + image size of half the amount of memory. + + There are two solutions to this: + + * require half of memory to be free during suspend. That way you can + read "new" data onto free spots, then cli and copy + + * assume we had special "polling" ide driver that only uses memory + between 0-640KB. That way, I'd have to make sure that 0-640KB is free + during suspending, but otherwise it would work... + + suspend2 shares this fundamental limitation, but does not include user + data and disk caches into "used memory" by saving them in + advance. That means that the limitation goes away in practice. + +Q: + Does linux support ACPI S4? + +A: + Yes. That's what echo platform > /sys/power/disk does. + +Q: + What is 'suspend2'? + +A: + suspend2 is 'Software Suspend 2', a forked implementation of + suspend-to-disk which is available as separate patches for 2.4 and 2.6 + kernels from swsusp.sourceforge.net. It includes support for SMP, 4GB + highmem and preemption. It also has a extensible architecture that + allows for arbitrary transformations on the image (compression, + encryption) and arbitrary backends for writing the image (eg to swap + or an NFS share[Work In Progress]). Questions regarding suspend2 + should be sent to the mailing list available through the suspend2 + website, and not to the Linux Kernel Mailing List. We are working + toward merging suspend2 into the mainline kernel. + +Q: + What is the freezing of tasks and why are we using it? + +A: + The freezing of tasks is a mechanism by which user space processes and some + kernel threads are controlled during hibernation or system-wide suspend (on some + architectures). See freezing-of-tasks.txt for details. + +Q: + What is the difference between "platform" and "shutdown"? + +A: + shutdown: + save state in linux, then tell bios to powerdown + + platform: + save state in linux, then tell bios to powerdown and blink + "suspended led" + + "platform" is actually right thing to do where supported, but + "shutdown" is most reliable (except on ACPI systems). + +Q: + I do not understand why you have such strong objections to idea of + selective suspend. + +A: + Do selective suspend during runtime power management, that's okay. But + it's useless for suspend-to-disk. (And I do not see how you could use + it for suspend-to-ram, I hope you do not want that). + + Lets see, so you suggest to + + * SUSPEND all but swap device and parents + * Snapshot + * Write image to disk + * SUSPEND swap device and parents + * Powerdown + + Oh no, that does not work, if swap device or its parents uses DMA, + you've corrupted data. You'd have to do + + * SUSPEND all but swap device and parents + * FREEZE swap device and parents + * Snapshot + * UNFREEZE swap device and parents + * Write + * SUSPEND swap device and parents + + Which means that you still need that FREEZE state, and you get more + complicated code. (And I have not yet introduce details like system + devices). + +Q: + There don't seem to be any generally useful behavioral + distinctions between SUSPEND and FREEZE. + +A: + Doing SUSPEND when you are asked to do FREEZE is always correct, + but it may be unnecessarily slow. If you want your driver to stay simple, + slowness may not matter to you.

Instead it does + protect from leaking sensitive data after resume from suspend. + + Think of the following: you suspend while an application is running + that keeps sensitive data in memory. The application itself prevents + the data from being swapped out. Suspend, however, must write these + data to swap to be able to resume later on. Without suspend encryption + your sensitive data are then stored in plaintext on disk. This means + that after resume your sensitive data are accessible to all + applications having direct access to the swap device which was used + for suspend. If you don't need swap after resume these data can remain + on disk virtually forever. Thus it can happen that your system gets + broken in weeks later and sensitive data which you thought were + encrypted and protected are retrieved and stolen from the swap device. + To prevent this situation you should use 'Encrypt suspend image'. + + During suspend a temporary key is created and this key is used to + encrypt the data written to disk. When, during resume, the data was + read back into memory the temporary key is destroyed which simply + means that all data written to disk during suspend are then + inaccessible so they can't be stolen later on. The only thing that + you must then take care of is that you call 'mkswap' for the swap + partition used for suspend as early as possible during regular + boot. This asserts that any temporary key from an oopsed suspend or + from a failed or aborted resume is erased from the swap device. + + As a rule of thumb use encrypted swap to protect your data while your + system is shut down or suspended. Additionally use the encrypted + suspend image to prevent sensitive data from being stolen after + resume. + +Q: + Can I suspend to a swap file? + +A: + Generally, yes, you can. However, it requires you to use the "resume=" and + "resume_offset=" kernel command line parameters, so the resume from a swap file + cannot be initiated from an initrd or initramfs image. See + swsusp-and-swap-files.txt for details. + +Q: + Is there a maximum system RAM size that is supported by swsusp? + +A: + It should work okay with highmem. + +Q: + Does swsusp (to disk) use only one swap partition or can it use + multiple swap partitions (aggregate them into one logical space)? + +A: + Only one swap partition, sorry. + +Q: + If my application(s) causes lots of memory & swap space to be used + (over half of the total system RAM), is it correct that it is likely + to be useless to try to suspend to disk while that app is running? + +A: + No, it should work okay, as long as your app does not mlock() + it. Just prepare big enough swap partition. + +Q: + What information is useful for debugging suspend-to-disk problems? + +A: + Well, last messages on the screen are always useful. If something + is broken, it is usually some kernel driver, therefore trying with as + little as possible modules loaded helps a lot. I also prefer people to + suspend from console, preferably without X running. Booting with + init=/bin/bash, then swapon and starting suspend sequence manually + usually does the trick. Then it is good idea to try with latest + vanilla kernel. + +Q: + How can distributions ship a swsusp-supporting kernel with modular + disk drivers (especially SATA)? + +A: + Well, it can be done, load the drivers, then do echo into + /sys/power/resume file from initrd. Be sure not to mount + anything, not even read-only mount, or you are going to lose your + data. + +Q: + How do I make suspend more verbose? + +A: + If you want to see any non-error kernel messages on the virtual + terminal the kernel switches to during suspend, you have to set the + kernel console loglevel to at least 4 (KERN_WARNING), for example by + doing:: + + # save the old loglevel + read LOGLEVEL DUMMY < /proc/sys/kernel/printk + # set the loglevel so we see the progress bar. + # if the level is higher than needed, we leave it alone. + if [ $LOGLEVEL -lt 5 ]; then + echo 5 > /proc/sys/kernel/printk + fi + + IMG_SZ=0 + read IMG_SZ < /sys/power/image_size + echo -n disk > /sys/power/state + RET=$? + # + # the logic here is: + # if image_size > 0 (without kernel support, IMG_SZ will be zero), + # then try again with image_size set to zero. + if [ $RET -ne 0 -a $IMG_SZ -ne 0 ]; then # try again with minimal image size + echo 0 > /sys/power/image_size + echo -n disk > /sys/power/state + RET=$? + fi + + # restore previous loglevel + echo $LOGLEVEL > /proc/sys/kernel/printk + exit $RET + +Q: + Is this true that if I have a mounted filesystem on a USB device and + I suspend to disk, I can lose data unless the filesystem has been mounted + with "sync"? + +A: + That's right ... if you disconnect that device, you may lose data. + In fact, even with "-o sync" you can lose data if your programs have + information in buffers they haven't written out to a disk you disconnect, + or if you disconnect before the device finished saving data you wrote. + + Software suspend normally powers down USB controllers, which is equivalent + to disconnecting all USB devices attached to your system. + + Your system might well support low-power modes for its USB controllers + while the system is asleep, maintaining the connection, using true sleep + modes like "suspend-to-RAM" or "standby". (Don't write "disk" to the + /sys/power/state file; write "standby" or "mem".) We've not seen any + hardware that can use these modes through software suspend, although in + theory some systems might support "platform" modes that won't break the + USB connections. + + Remember that it's always a bad idea to unplug a disk drive containing a + mounted filesystem. That's true even when your system is asleep! The + safest thing is to unmount all filesystems on removable media (such USB, + Firewire, CompactFlash, MMC, external SATA, or even IDE hotplug bays) + before suspending; then remount them after resuming. + + There is a work-around for this problem. For more information, see + Documentation/driver-api/usb/persist.rst. + +Q: + Can I suspend-to-disk using a swap partition under LVM? + +A: + Yes and No. You can suspend successfully, but the kernel will not be able + to resume on its own. You need an initramfs that can recognize the resume + situation, activate the logical volume containing the swap volume (but not + touch any filesystems!), and eventually call:: + + echo -n "$major:$minor" > /sys/power/resume + + where $major and $minor are the respective major and minor device numbers of + the swap volume. + + uswsusp works with LVM, too. See http://suspend.sourceforge.net/ + +Q: + I upgraded the kernel from 2.6.15 to 2.6.16. Both kernels were + compiled with the similar configuration files. Anyway I found that + suspend to disk (and resume) is much slower on 2.6.16 compared to + 2.6.15. Any idea for why that might happen or how can I speed it up? + +A: + This is because the size of the suspend image is now greater than + for 2.6.15 (by saving more data we can get more responsive system + after resume). + + There's the /sys/power/image_size knob that controls the size of the + image. If you set it to 0 (eg. by echo 0 > /sys/power/image_size as + root), the 2.6.15 behavior should be restored. If it is still too + slow, take a look at suspend.sf.net -- userland suspend is faster and + supports LZF compression to speed it up further. diff --git a/Documentation/power/swsusp.txt b/Documentation/power/swsusp.txt deleted file mode 100644 index 236d1fb13640..000000000000 --- a/Documentation/power/swsusp.txt +++ /dev/null @@ -1,446 +0,0 @@ -Some warnings, first. - - * BIG FAT WARNING ********************************************************* - * - * If you touch anything on disk between suspend and resume... - * ...kiss your data goodbye. - * - * If you do resume from initrd after your filesystems are mounted... - * ...bye bye root partition. - * [this is actually same case as above] - * - * If you have unsupported (*) devices using DMA, you may have some - * problems.

It -saves the state of the machine to a filesystem or to a partition and switches -to standby mode. Later resuming the machine the saved state is loaded back to -ram and the machine can continue its work. It has two real benefits. First we -save ourselves the time machine goes down and later boots up, energy costs -are real high when running from batteries. The other gain is that we don't have to -interrupt our programs so processes that are calculating something for a long -time shouldn't need to be written interruptible. - -swsusp saves the state of the machine into active swaps and then reboots or -powerdowns. You must explicitly specify the swap partition to resume from with -``resume='' kernel option. If signature is found it loads and restores saved -state. If the option ``noresume'' is specified as a boot parameter, it skips -the resuming.

It includes support for SMP, 4GB -highmem and preemption. It also has a extensible architecture that -allows for arbitrary transformations on the image (compression, -encryption) and arbitrary backends for writing the image (eg to swap -or an NFS share[Work In Progress]).

We are working -toward merging suspend2 into the mainline kernel. - -Q: What is the freezing of tasks and why are we using it? - -A: The freezing of tasks is a mechanism by which user space processes and some -kernel threads are controlled during hibernation or system-wide suspend (on some -architectures).

This patch adds SO_DETACH_REUSEPORT_BPF sockopt. The same sockopt can be used to undo both SO_ATTACH_REUSEPORT_[CE]BPF. reseport_detach_prog() is added and it is mostly a mirror of the existing reuseport_attach_prog(). The differences are, it does not call reuseport_alloc() and returns -ENOENT when there is no old prog.

Note that we do not need to use that area for control blocks directly referenced by instructions, e.g. the orb. It handles neither QDIO in the common code, nor any device type specific stuff (like channel programs constructed by the DASD driver). An interesting side effect is that virtio structures are now going to get allocated in 31 bit addressable storage.

On a virtual system where not all logical CPUs are backed by real CPUs all the time it can take a while for all CPUs to check-in. With the current definition of cpu_relax_yield a diagnose 0x44 is done which tells the hypervisor to schedule *some* other CPU. That can be any CPU and not necessarily one of the CPUs that need to run in order to advance the state machine. This can lead to a pretty bad diagnose 0x44 storm until the last missing CPU finally checked-in. Replace the undirected cpu_relax_yield based on diagnose 0x44 with a directed yield. Each CPU in the wait loop will pick up the next CPU in the cpumask of stop_machine. The diagnose 0x9c is used to tell the hypervisor to run this next CPU instead of the current one. If there is only a limited number of real CPUs backing the virtual CPUs we end up with the real CPUs passed around in a round-robin fashion.

The number of IPIs then is linear with regard to the number 'n' of entries of a key: O(n*3), which is O(n). This algorithm works fine for the update of a single key. But we think it is possible to optimize the case in which a static key has more than one entry. For instance, the sched_schedstats jump label has 56 entries in my (updated) fedora kernel, resulting in 168 IPIs for each CPU in which the thread that is enabling the key is _not_ running. With this patch, rather than receiving a single patch to be processed, a vector of patches is passed, enabling the rewrite of the pseudo-code #1 in this way: -- Pseudo-code #2 - This patch --- 1) for each patch in the vector: add an int3 trap to the address that will be patched sync cores (send IPI to all other CPUs) 2) for each patch in the vector: update all but the first byte of the patched range sync cores (send IPI to all other CPUs) 3) for each patch in the vector: replace the first byte (int3) by the first byte of replacing opcode sync cores (send IPI to all other CPUs) -- Pseudo-code #2 - This patch --- Doing the update in this way, the number of IPI becomes O(3) with regard to the number of keys, which is O(1). The batch mode is done with the function text_poke_bp_batch(), that receives two arguments: a vector of "struct text_to_poke", and the number of entries in the vector. The vector must be sorted by the addr field of the text_to_poke structure, enabling the binary search of a handler in the poke_int3_handler function (a fast path).

This functions returns true in the case of a successful enqueue of an entry. If it returns false, the caller must to apply the queue and then try to queue again, for instance, because the queue is full. This function expects the caller to sort the entries by the address before enqueueuing then. This is already done by the arch independent code, though. After queuing all jump_entries, the function: void arch_jump_label_transform_apply(void) Applies the changes in the queue.

Strongly ordered architectures where the atomic RmW primitive implies full memory ordering and smp_mb__{before,after}_atomic() are a simple barrier() (such as x86) fail for: *x = 1; atomic_inc(u); smp_mb__after_atomic(); r0 = *y; Because, while the atomic_inc() implies memory order, it (surprisingly) does not provide a compiler barrier. This then allows the compiler to re-order like so: atomic_inc(u); *x = 1; smp_mb__after_atomic(); r0 = *y; Which the CPU is then allowed to re-order (under TSO rules) like: atomic_inc(u); r0 = *y; *x = 1; And this very much was not intended. Therefore strengthen the atomic RmW ops to include a compiler barrier. NOTE: atomic_{or,and,xor} and the bitops already had the compiler barrier.

The uncore units on Snow Ridge include Ubox, Chabox, IIO, IRP, M2PCIE, PCU, M2M, PCIE3 and IMC. - The config register encoding and pci device IDs are changed. - For CHA, the umask_ext and filter_tid fields are changed. - For IIO, the ch_mask and fc_mask fields are changed. - For M2M, the mask_ext field is changed. - Add new PCIe3 unit for PCIe3 root port which provides the interface between PCIe devices, plugged into the PCIe port, and the components (in M2IOSF). - IMC can only be accessed via MMIO on Snow Ridge now. Current common code doesn't support it yet. IMC will be supported in following patches. - There are 9 free running counters for IIO CLOCKS and bandwidth In. - Full uncore event list is not published yet. Event constrain is not included in this patch. It will be added later separately.

The uncore boxes need to be initalized and exited accordingly for the first/last CPU of a socket. Starts from Snow Ridge server, a new type of uncore box is introduced, which can only be accessed by MMIO. The driver needs to map/unmap MMIO space for the first/last CPU of a socket. Extract the codes of box ref/unref and init/exit for reuse later. There is no functional change.

The thing is, the this_cpu_*() operations are defined IRQ-safe, this means the values are subject to change from IRQs, and thus must be reloaded. Also, the generic form: local_irq_save() __this_cpu_read() local_irq_restore() would not allow the re-use of previous values; if by nothing else, then the barrier()s implied by local_irq_*(). Which raises the point that percpu_from_op() and the others also need that volatile. OTOH __this_cpu_*() operations are not IRQ-safe and assume external preempt/IRQ disabling and could thus be allowed more room for optimization. This makes the this_cpu_*() vs __this_cpu_*() behaviour more consistent with other architectures. $ ./compare.sh defconfig-build defconfig-build1 vmlinux.o x86_pmu_cancel_txn 80 71 -9,+0 __text_poke 919 964 +45,+0 do_user_addr_fault 1082 1058 -24,+0 __do_page_fault 1194 1178 -16,+0 do_exit 2995 3027 -43,+75 process_one_work 1008 989 -67,+48 finish_task_switch 524 505 -19,+0 __schedule_bug 103 98 -59,+54 __schedule_bug 103 98 -59,+54 __sched_setscheduler 2015 2030 +15,+0 freeze_processes 203 230 +31,-4 rcu_gp_kthread_wake 106 99 -7,+0 rcu_core 1841 1834 -7,+0 call_timer_fn 298 286 -12,+0 can_stop_idle_tick 146 139 -31,+24 perf_pending_event 253 239 -14,+0 shmem_alloc_page 209 213 +4,+0 __alloc_pages_slowpath 3284 3269 -15,+0 umount_tree 671 694 +23,+0 advance_transaction 803 798 -5,+0 con_put_char 71 51 -20,+0 xhci_urb_enqueue 1302 1295 -7,+0 xhci_urb_enqueue 1302 1295 -7,+0 tcp_sacktag_write_queue 2130 2075 -55,+0 tcp_try_undo_loss 229 208 -21,+0 tcp_v4_inbound_md5_hash 438 411 -31,+4 tcp_v4_inbound_md5_hash 438 411 -31,+4 tcp_v6_inbound_md5_hash 469 411 -33,-25 tcp_v6_inbound_md5_hash 469 411 -33,-25 restricted_pointer 434 420 -14,+0 irq_exit 162 154 -8,+0 get_perf_callchain 638 624 -14,+0 rt_mutex_trylock 169 156 -13,+0 avc_has_extended_perms 1092 1089 -3,+0 avc_has_perm_noaudit 309 306 -3,+0 __perf_sw_event 138 122 -16,+0 perf_swevent_get_recursion_context 116 102 -14,+0 __local_bh_enable_ip 93 72 -21,+0 xfrm_input 4175 4161 -14,+0 avc_has_perm 446 443 -3,+0 vm_events_fold_cpu 57 56 -1,+0 vfree 68 61 -7,+0 freeze_processes 203 230 +31,-4 _local_bh_enable 44 30 -14,+0 ip_do_fragment 1982 1944 -38,+0 do_exit 2995 3027 -43,+75 __do_softirq 742 724 -18,+0 cpu_init 1510 1489 -21,+0 account_system_time 80 79 -1,+0 total 12985281 12984819 -742,+280 Reported-by: Nadav Amit Signed-off-by: Peter Zijlstra (Intel) Cc: Linus Torvalds Cc: Peter Zijlstra Cc: Thomas Gleixner Link: https://lkml.kernel.org/r/20181206112433.GB13675@hirez.programming.kicks-ass.net Signed-off-by: Ingo Molnar --- arch/x86/include/asm/percpu.h | 224 +++++++++++++++++++++--------------------- 1 file changed, 112 insertions(+), 112 deletions(-) (limited to 'arch') diff --git a/arch/x86/include/asm/percpu.h b/arch/x86/include/asm/percpu.h index 1a19d11cfbbd..f75ccccd71aa 100644 --- a/arch/x86/include/asm/percpu.h +++ b/arch/x86/include/asm/percpu.h @@ -87,7 +87,7 @@ * don't give an lvalue though). */ extern void __bad_percpu_size(void);

However since smp_processor_id() is reading a stable value, we can use __this_cpu_read(). While this does reduce text size somewhat, this mostly results in code movement to .text.unlikely as a result of more/larger .cold. subfunctions.

This hcall is handled in the host in kvmppc_h_set_dawr() which can be called in either real mode on the guest exit path from hcall_try_real_mode() in book3s_hv_rmhandlers.S, or in virtual mode when called from kvmppc_pseries_do_hcall() in book3s_hv.c. The function kvmppc_h_set_dawr() updates the dawr and dawrx fields in the vcpu struct accordingly and then also writes the respective values into the DAWR and DAWRX registers directly. It is necessary to write the registers directly here when calling the function in real mode since the path to re-enter the guest won't do this. However when in virtual mode the host DAWR and DAWRX values have already been restored, and so writing the registers would overwrite these. Additionally there is no reason to write the guest values here as these will be read from the vcpu struct and written to the registers appropriately the next time the vcpu is run. This also avoids the case when handling h_set_dawr for a nested guest where the guest hypervisor isn't able to write the DAWR and DAWRX registers directly and must rely on the real hypervisor to do this for it when it calls H_ENTER_NESTED.

It is plausible that some boards could shut down important rails in S3. Also note that currently wakeup doesn't seem to happen unless you use the "deep" suspend mode (where SDRAM is turned off). Presumably the shallow suspend mode is gating some sort of clock that's important but I couldn't easily figure out how to get it working.

As it pertains to this bug fix, the third case explicitly states EXIT_REASON_MCE_DURING_VMENTRY is handled like any other VM-Exit during VM-Entry, i.e. sets bit 31 to indicate the VM-Entry failed. If a machine-check event occurs during a VM entry, one of the following occurs: - The machine-check event is handled as if it occurred before the VM entry: ... - The machine-check event is handled after VM entry completes: ... - A VM-entry failure occurs as described in Section 26.7. The basic exit reason is 41, for "VM-entry failure due to machine-check event". Explicitly handle EXIT_REASON_MCE_DURING_VMENTRY as a one-off case in vmx_vcpu_run() instead of binning it into vmx_complete_atomic_exit(). Doing so allows vmx_vcpu_run() to handle VMX_EXIT_REASONS_FAILED_VMENTRY in a sane fashion and also simplifies vmx_complete_atomic_exit() since VMCS.VM_EXIT_INTR_INFO is guaranteed to be fresh.

Use the already-cached EXIT_REASON to determine if the VM-Exit was due to an interrupt, thus avoiding an extra VMREAD (to query VM_EXIT_INTR_INFO) for all other types of VM-Exit. In addition to avoiding the extra VMREAD, checking the EXIT_REASON instead of VM_EXIT_INTR_INFO makes it more obvious that vmx_handle_external_intr() is called for all VM-Exits, e.g. someone unfamiliar with the flow might wonder under what condition(s) VM_EXIT_INTR_INFO does not contain a valid interrupt, which is simply not possible since KVM always runs with "ack interrupt on exit". WARN once if VM_EXIT_INTR_INFO doesn't contain a valid interrupt on an EXTERNAL_INTERRUPT VM-Exit, as such a condition would indicate a hardware bug.

Before commit a547c6db4d2f1 ("KVM: VMX: Enable acknowledge interupt on vmexit"), the kernel's IDT base was consumed by KVM only when setting constant VMCS state, i.e. to set VMCS.HOST_IDTR_BASE. Because constant host state is done once per vCPU, there was ostensibly no need to cache the kernel's IDT base. When support for "ack interrupt on exit" was introduced, KVM added a second consumer of the IDT base as handling already-acked interrupts requires directly calling the interrupt handler, i.e. KVM uses the IDT base to find the address of the handler. Because interrupts are a fast path, KVM cached the IDT base to avoid having to VMREAD HOST_IDTR_BASE. Presumably, the IDT base was cached on a per-vCPU basis simply because the existing code grabbed the IDT base on a per-vCPU (VMCS) basis. Note, all post-boot IDTs use the same handlers for external interrupts, i.e. the "ack interrupt on exit" use of the IDT base would be unaffected even if the cached IDT somehow did not match the current IDT. And as for the original use case of setting VMCS.HOST_IDTR_BASE, if any of the above analysis is wrong then KVM has had a bug since the beginning of time since KVM has effectively been caching the IDT at vCPU creation since commit a8b732ca01c ("[PATCH] kvm: userspace interface").

The other exceptions handled by complete_atomic_exit(), e.g. async #PF and #MC, have similar requirements, and are located there to avoid extra VMREADs since VMX bins hardware exceptions and NMIs into a single exit reason. Clean up the code and eliminate the vaguely named complete_atomic_exit() by moving the interrupts-disabled exception and NMI handling into the existing handle_external_intrs() callback, and rename the callback to a more appropriate name. Rename VMexit handlers throughout so that the atomic and non-atomic counterparts have similar names. In addition to improving code readability, this also ensures the NMI handler is run with the host's debug registers loaded in the unlikely event that the user is debugging NMIs. Accuracy of the last_guest_tsc field is also improved when handling NMIs (and #MCs) as the handler will run after updating said field.

Intercepting RO fields means KVM doesn't need to sync them from the shadow VMCS to vmcs12 when running L2. The obvious downside is that L1 will VM-Exit more often when running L3, but it's likely safe to assume most folks would happily sacrifice a bit of L3 performance, which may not even be noticeable in the grande scheme, to improve L2 performance across the board. Not intercepting fields tagged read-only also allows for additional optimizations, e.g. marking GUEST_{CS,SS}_AR_BYTES as SHADOW_FIELD_RO since those fields are rarely written by a VMMs, but read frequently. When utilizing a shadow VMCS with asymmetric R/W and R/O bitmaps, fields that cause VM-Exit on VMWRITE but not VMREAD need to be propagated to the shadow VMCS during VMWRITE emulation, otherwise a subsequence VMREAD from L1 will consume a stale value. Note, KVM currently utilizes asymmetric bitmaps when "VMWRITE any field" is not exposed to L1, but only so that it can reject the VMWRITE, i.e. propagating the VMWRITE to the shadow VMCS is a new requirement, not a bug fix. Eliminating the copying of RO fields reduces the latency of nested VM-Entry (copy_shadow_to_vmcs12()) by ~100 cycles (plus 40-50 cycles if/when the AR_BYTES fields are exposed RO).

Intercepting VMWRITEs for the two fields saves ~55 cycles in copy_shadow_to_vmcs12(). Because some Intel CPUs, e.g. Haswell, drop the reserved bits of the guest access rights fields on VMWRITE, exposing the fields to L1 for VMREAD but not VMWRITE leads to inconsistent behavior between L1 and L2. On hardware that drops the bits, L1 will see the stripped down value due to reading the value from hardware, while L2 will see the full original value as stored by KVM. To avoid such an inconsistency, emulate the behavior on all CPUS, but only for intercepted VMWRITEs so as to avoid introducing pointless latency into copy_shadow_to_vmcs12(), e.g. if the emulation were added to vmcs12_write_any(). Since the AR_BYTES emulation is done only for intercepted VMWRITE, if a future patch (re)exposed AR_BYTES for both VMWRITE and VMREAD, then KVM would end up with incosistent behavior on pre-Haswell hardware, e.g. KVM would drop the reserved bits on intercepted VMWRITE, but direct VMWRITE to the shadow VMCS would not drop the bits. Add a WARN in the shadow field initialization to detect any attempt to expose an AR_BYTES field without updating vmcs12_write_any(). Note, emulation of the AR_BYTES reserved bit behavior is based on a patch[1] from Jim Mattson that applied the emulation to all writes to vmcs12 so that live migration across different generations of hardware would not introduce divergent behavior. But given that live migration of nested state has already been enabled, that ship has sailed (not to mention that no sane VMM will be affected by this behavior).

Delay pulling rarely accessed guest fields from vmcs02 until they are VMREAD or until vmcs12 is dirtied. The latter case is necessary because nested VM-Entry will consume all manner of fields when vmcs12 is dirty, e.g. for consistency checks. Note, an alternative to synchronizing all guest fields on VMREAD would be to read *only* the field being accessed, but switching VMCS pointers is expensive and odds are good if one guest field is being accessed then others will soon follow, or that vmcs12 will be dirtied due to a VMWRITE (see above). And the full synchronization results in slightly cleaner code. Note, although GUEST_PDPTRs are relevant only for a 32-bit PAE guest, they are accessed quite frequently for said guests, and a separate patch is in flight to optimize away GUEST_PDTPR synchronziation for non-PAE guests.

If guest state is already loaded (the likely, if not guaranteed, case), keep the guest state loaded and manually swap the loaded_cpu_state pointer after propagating saved host state to the new vmcs0{1,2}. Avoiding the switch between guest and host reduces the latency of switching between vmcs01 and vmcs02 by several hundred cycles, and reduces the roundtrip time of a nested VM by upwards of 1000 cycles.

A VM entry to a guest that uses PAE paging loads the PDPTEs into internal, non-architectural registers based on the setting of the "enable EPT" VM-execution control. and: [GUEST_PDPTR] values are saved into the four PDPTE fields as follows: - If the "enable EPT" VM-execution control is 0 or the logical processor was not using PAE paging at the time of the VM exit, the values saved are undefined. In other words, if EPT is disabled or the guest isn't using PAE paging, then the PDPTRS aren't consumed by hardware on VM-Entry and are loaded with junk on VM-Exit. From a nesting perspective, all of the above hold true, i.e. KVM can effectively ignore the VMCS PDPTRs. E.g. KVM already loads the PDPTRs from memory when nested EPT is disabled (see nested_vmx_load_cr3()). Because KVM intercepts setting CR4.PAE, there is no danger of consuming a stale value or crushing L1's VMWRITEs regardless of whether L1 intercepts CR4.PAE. The vmcs12's values are unchanged up until the VM-Exit where L2 sets CR4.PAE, i.e. L0 will see the new PAE state on the subsequent VM-Entry and propagate the PDPTRs from vmcs12 to vmcs02.

VMWRITEs to the major VMCS controls are deceptively expensive. Intel CPUs with VMCS caching (Westmere and later) also optimize away consistency checks on VM-Entry, i.e. skip consistency checks if the relevant fields have not changed since the last successful VM-Entry (of the cached VMCS). Because uops are a precious commodity, uCode's dirty VMCS field tracking isn't as precise as software would prefer. Notably, writing any of the major VMCS fields effectively marks the entire VMCS dirty, i.e. causes the next VM-Entry to perform all consistency checks, which consumes several hundred cycles. Zero out the controls' shadow copies during VMCS allocation and use the optimized setter when "initializing" controls. While this technically affects both non-nested and nested virtualization, nested virtualization is the primary beneficiary as avoid VMWRITEs when prepare vmcs02 allows hardware to optimizie away consistency checks.

CPUs with VMCS caching (Westmere and later) also optimize away consistency checks on VM-Entry, i.e. skip consistency checks if the relevant fields have not changed since the last successful VM-Entry (of the cached VMCS). Because uops are a precious commodity, uCode's dirty VMCS field tracking isn't as precise as software would prefer. Notably, writing any of the major VMCS fields effectively marks the entire VMCS dirty, i.e. causes the next VM-Entry to perform all consistency checks, which consumes several hundred cycles. As it pertains to KVM, toggling PIN_BASED_VMX_PREEMPTION_TIMER more than doubles the latency of the next VM-Entry (and again when/if the flag is toggled back). In a non-nested scenario, running a "standard" guest with the preemption timer enabled, toggling the timer flag is uncommon but not rare, e.g. roughly 1 in 10 entries. Disabling the preemption timer can change these numbers due to its use for "immediate exits", even when explicitly disabled by userspace. Nested virtualization in particular is painful, as the timer flag is set for the majority of VM-Enters, but prepare_vmcs02() initializes vmcs02's pin controls to *clear* the flag since its the timer's final state isn't known until vmx_vcpu_run(). I.e. the majority of nested VM-Enters end up unnecessarily writing pin controls *twice*. Rather than toggle the timer flag in pin controls, set the timer value itself to the largest allowed value to put it into a "soft disabled" state, and ignore any spurious preemption timer exits. Sadly, the timer is a 32-bit value and so theoretically it can fire before the head death of the universe, i.e. spurious exits are possible. But because KVM does *not* save the timer value on VM-Exit and because the timer runs at a slower rate than the TSC, the maximuma timer value is still sufficiently large for KVM's purposes. E.g. on a modern CPU with a timer that runs at 1/32 the frequency of a 2.4ghz constant-rate TSC, the timer will fire after ~55 seconds of *uninterrupted* guest execution. In other words, spurious VM-Exits are effectively only possible if the host is completely tickless on the logical CPU, the guest is not using the preemption timer, and the guest is not generating VM-Exits for any other reason. To be safe from bad/weird hardware, disable the preemption timer if its maximum delay is less than ten seconds. Ten seconds is mostly arbitrary and was selected in no small part because it's a nice round number. For simplicity and paranoia, fall back to __kvm_request_immediate_exit() if the preemption timer is disabled by KVM or userspace. Previously KVM continued to use the preemption timer to force immediate exits even when the timer was disabled by userspace. Now that KVM leaves the timer running instead of truly disabling it, allow userspace to kill it entirely in the unlikely event the timer (or KVM) malfunctions.

Since it does not affect KVM's dirty logic, e.g. the preemption timer value is loaded from vmcs12 even if vmcs12 is "clean", there is no need to mark vmcs12 dirty when L1 writes pin controls, and shadowing the field achieves that.

It missed that the callbacks invoke sysfs functions which might sleep causing nice 'might sleep' splats with proper debugging enabled. Split the callbacks and only load the microcode in the early startup phase and move the sysfs handling back into the later threaded and preemptible bringup phase where it was before.

Add-n card options add further functionality (such as additional Audio, Display, networking options). Note: A) The minimum configuration required to boot up the board is System On Module(SOM) + Common Processor Board. B) Since there is just a single SOM and Common Processor Board, we are maintaining common processor board as the base dts and SOM as the dtsi that we include. In the future as more SOM's appear, we should move common processor board as a dtsi and include configurations as dts. C) All daughter cards beyond the basic boards shall be maintained as overlays.

Nest and core IMC (In-Memory Collection counters) assigns a particular cpu as the designated target for counter data collection. During system boot, the first online cpu in a chip gets assigned as the designated cpu for that chip(for nest-imc) and the first online cpu in a core gets assigned as the designated cpu for that core(for core-imc). If the designated cpu goes offline, the next online cpu from the same chip(for nest-imc)/core(for core-imc) is assigned as the next target, and the event context is migrated to the target cpu. Currently, cpumask_any_but() function is used to find the target cpu. Though this function is expected to return a `random` cpu, this always returns the next online cpu. If all cpus in a chip/core is offlined in a sequential manner, starting from the first cpu, the event migration has to happen for all the cpus which goes offline. Since the migration process involves a grace period, the total time taken to offline all the cpus will be significantly high. Example: In a system which has 2 sockets, with NUMA node0 CPU(s): 0-87 NUMA node8 CPU(s): 88-175 Time taken to offline cpu 88-175: real 2m56.099s user 0m0.191s sys 0m0.000s Use cpumask_last() to choose the target cpu, when the designated cpu goes online, so the migration will happen only when the last_cpu in the mask goes offline. This way the time taken to offline all cpus in a chip/core can be reduced. With the patch: Time taken to offline cpu 88-175: real 0m12.207s user 0m0.171s sys 0m0.000s Offlining all cpus in reverse order is also taken care because, cpumask_any_but() is used to find the designated cpu if the last cpu in the mask goes offline. Since cpumask_any_but() always return the first cpu in the mask, that becomes the designated cpu and migration will happen only when the first_cpu in the mask goes offline.

In order to avoid changing the ioctl values of KVM_{GET,SET}_NESTED_STATE, there is a need to preserve sizeof(struct kvm_nested_state). This is done by defining the data struct as "data.vmx[0]". It was the most elegant way I found to preserve struct size while still keeping struct readable and easy to maintain. It does have a misfortunate side-effect that now it has to be accessed as "data.vmx[0]" rather than just "data.vmx". Because we are already modifying these structs, I also modified the following: * Define the "format" field values as macros. * Rename vmcs_pa to vmcs12_pa for better readability.

Just remove the old defconfig and replace it with performance_defconfig, which reduces the number of configs to maintain. A config with debugging options enabled is debug_defconfig which is supposed to be rather close to performance_defconfig except that is has debug options enabled.

s390: fix stfle zero padding The stfle inline assembly returns the number of double words written (condition code 0) or the double words it would have written (condition code 3), if the memory array it got as parameter would have been large enough. The current stfle implementation assumes that the array is always large enough and clears those parts of the array that have not been written to with a subsequent memset call. If however the array is not large enough memset will get a negative length parameter, which means that memset clears memory until it gets an exception and the kernel crashes. To fix this simply limit the maximum length. Move also the inline assembly to an extra function to avoid clobbering of register 0, which might happen because of the added min_t invocation together with code instrumentation. The bug was introduced with commit 14375bc4eb8d ("[S390] cleanup facility list handling") but was rather harmless, since it would only write to a rather large array. It became a potential problem with commit 3ab121ab1866 ("[S390] kernel: Add z/VM LGR detection"). Since then it writes to an array with only four double words, while some machines already deliver three double words. As soon as machines have a facility bit within the fifth double a crash on IPL would happen.

When trying to use Clang with LLVM's integrated assembler, this leads to build errors such as this: clang-8: error: the clang compiler does not support '-Wa,-march=armv7-a+sec' Use ".arch_extension sec" to enable the security extension in a more portable fasion. Also make sure to use ".arch armv7-a" in case a v6/v7 multi-platform kernel is being built. Note that this is technically not exactly the same as the old code checked for availabilty of the security extension by calling as-instr. However, there are already other sites which use ".arch_extension sec" unconditionally, hence de-facto we need an assembler capable of ".arch_extension sec" already today (arch/arm/mm/proc-v7.S). The arch extension "sec" is available since binutils 2.21 according to its documentation [1].

The datasheet describes that they are "3.3V input tolerant open drain (OD) output pins". This means the GPIO controller can drive the output LOW to reset the PHY. To release the reset it can only switch the pin to input mode. The output cannot be driven HIGH for these pins. This requires configuring the reset line as GPIO_OPEN_DRAIN because otherwise the PHY will be stuck in "reset" state (because driving the pin HIGH seems to result in the same signal as driving it LOW). The reset line works together with a pull-up resistor (R143 in the Odroid-N2 schematics). The SoC can drive GPIOZ_14 LOW to assert the PHY reset. However, since the SoC can't drive the pin HIGH (to release the reset) we switch the mode to INPUT and let the pull-up resistor take care of driving the reset line HIGH. Switch to GPIOZ_15 for the PHY reset line instead of using GPIOZ_14 (which actually is the interrupt line). Move from the "snps" specific resets to the MDIO framework's reset-gpios because only the latter honors the GPIO flags. Use the GPIO flags (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN) to match with the pull-up resistor because this will: - drive the output LOW to reset the PHY (= active low) - switch the pin to INPUT mode so the pull-up will take the PHY out of reset Fixes: 51d116557b2044 ("arm64: dts: meson-g12a-x96-max: Add Gigabit Ethernet Support") Reviewed-by: Neil Armstrong Signed-off-by: Martin Blumenstingl Signed-off-by: Kevin Hilman --- arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'arch') diff --git a/arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts b/arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts index d37868d21114..3f9385553132 100644 --- a/arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts +++ b/arch/arm64/boot/dts/amlogic/meson-g12a-x96-max.dts @@ -285,6 +285,10 @@ reg = <0>; max-speed = <1000>; eee-broken-1000t; + + reset-assert-us = <10000>; + reset-deassert-us = <30000>; + reset-gpios = <&gpio GPIOZ_15 (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN)>; }; }; @@ -295,9 +299,6 @@ phy-mode = "rgmii"; phy-handle = <&external_phy>; amlogic,tx-delay-ns = <2>; - snps,reset-gpio = <&gpio GPIOZ_14 0>; - snps,reset-delays-us = <0 10000 1000000>; - snps,reset-active-low; }; &pwm_ef { -- cgit v1.2.3 From f29cabf240ed6e67993f17594e5e6fffc5bc07e0 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 15 Jun 2019 12:38:31 +0200 Subject: arm64: dts: meson: use the generic Ethernet PHY reset GPIO bindings The snps,reset-gpio bindings are deprecated in favour of the generic "Ethernet PHY reset" bindings. Replace snps,reset-gpio from the ðmac node with reset-gpios in the ethernet-phy node. The old snps,reset-active-low property is now encoded directly as GPIO flag inside the reset-gpios property. snps,reset-delays-us is converted to reset-assert-us and reset-deassert-us. reset-assert-us is the second cell from snps,reset-delays-us while reset-deassert-us was the third cell. Instead of blindly copying the old values (which seems strange since they gave the PHY one second to come out of reset) over this also updates the delays based on the datasheets: - the Realtek RTL8211F PHY needs a 10ms assert delay (the datasheet mentions: "For a complete PHY reset, this pin must be asserted low for at least 10ms") and a 30ms deassert delay (the datasheet mentions: "Wait for a further 30ms (for internal circuits settling time) before accessing the PHY register". This applies to the following boards: GXBB NanoPi K2, GXBB Odroid-C2, GXBB Vega S95 variants, GXBB Wetek variants, GXL P230, GXM Khadas VIM2, GXM Nexbox A1, GXM Q200, GXM RBox Pro boards. - the ICPlus IP101GR PHY needs a 10ms assert delay (the datasheet mentions: "Trst | Reset period | 10ms") and a deassert delay of 10ms as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock output ready after reset released | 10ms"). This applies to the GXBB Nexbox A95X board. - the Micrel KSZ9031 seems to require a 100us delay but use the same (seemingly safe) values from RTL8211F due to lack of a board to verify this. This applies to the GXBB P200 board. The GXBB P201 board is left out from this conversion because it doesn't have a dedicated PHY node (because it's not clear which PHY is used on that board).

Describe this in the device tree so the PHY framework can bring the PHY into a known state when initializing it. GPIOZ_15 doesn't support driving the output HIGH (to take the PHY out of reset, only output LOW to reset the PHY is supported). The datasheet states it's an "3.3V input tolerant open drain (OD) output pin". Instead there's a pull-up resistor on the board to take the PHY out of reset. The GPIO itself will be set to INPUT mode to take the PHY out of reset and LOW to reset the PHY, which is achieved with the flags (GPIO_ACTIVE_LOW | GPIO_OPEN_DRAIN).

The flags are stored in resource::flags - the lower byte stores PCI_BASE_ADDRESS_SPACE/etc bits and the other bytes are IORESOURCE_IO/etc. Some flags from PCI_BASE_ADDRESS_xxx and IORESOURCE_xxx are duplicated, such as PCI_BASE_ADDRESS_MEM_PREFETCH/PCI_BASE_ADDRESS_MEM_TYPE_64/etc. When parsing the "reg" property, we copy the prefetch flag but we skip on PCI_BASE_ADDRESS_MEM_TYPE_64 which leaves the flags out of sync. The missing IORESOURCE_MEM_64 flag comes into play under 2 conditions: 1. we remove PCI_PROBE_ONLY for pseries (by hacking pSeries_setup_arch() or by passing "/chosen/linux,pci-probe-only"); 2. we request resource alignment (by passing pci=resource_alignment= via the kernel cmd line to request PAGE_SIZE alignment or defining ppc_md.pcibios_default_alignment which returns anything but 0). Note that the alignment requests are ignored if PCI_PROBE_ONLY is enabled. With 1) and 2), the generic PCI code in the kernel unconditionally decides to: - reassign the BARs in pci_specified_resource_alignment() (works fine) - write new BARs to the device - this fails for 64bit BARs as the generic code looks at IORESOURCE_MEM_64 (not set) and writes only lower 32bits of the BAR and leaves the upper 32bit unmodified which breaks BAR mapping in the hypervisor. This fixes the issue by copying the flag. This is useful if we want to enforce certain BAR alignment per platform as handling subpage sized BARs is proven to cause problems with hotplug (SLOF already aligns BARs to 64k).

This SME workarea used during early encryption of the kernel is situated on a 2MB boundary after the end of the kernel text, data, etc. sections (_end). This works well during initial boot of a compressed kernel because of the relocation used for decompression of the kernel. But when performing a kexec boot, there's a chance that the SME workarea may not be mapped by the kexec pagetables or that some of the other data used by kexec could exist in this range. Create a section for SME in vmlinux.lds.S. Position it after "_end", which is after "__end_of_kernel_reserve", so that the memory will be reclaimed during boot and since this area is all zeroes, it compresses well. This new section will be part of the kernel image, so kexec will account for it in pagetable mappings and placement of data after the kernel. Here's an example of a kernel size without and with the SME section: without: vmlinux: 36,501,616 bzImage: 6,497,344 100000000-47f37ffff : System RAM 1e4000000-1e47677d4 : Kernel code (0x7677d4) 1e47677d5-1e4e2e0bf : Kernel data (0x6c68ea) 1e5074000-1e5372fff : Kernel bss (0x2fefff) with: vmlinux: 44,419,408 bzImage: 6,503,136 880000000-c7ff7ffff : System RAM 8cf000000-8cf7677d4 : Kernel code (0x7677d4) 8cf7677d5-8cfe2e0bf : Kernel data (0x6c68ea) 8d0074000-8d0372fff : Kernel bss (0x2fefff) Signed-off-by: Tom Lendacky Signed-off-by: Borislav Petkov Reviewed-by: Baoquan He Reviewed-by: Dave Hansen Tested-by: Lianbo Jiang Cc: Andy Lutomirski Cc: Brijesh Singh Cc: "H.

But the kernel can not exactly match the e820 reserved ranges when walking through the iomem resources using the default IORES_DESC_NONE descriptor, because there are several types of e820 ranges which are marked IORES_DESC_NONE, see e820_type_to_iores_desc(). Therefore, add a new I/O resource descriptor called IORES_DESC_RESERVED to mark exactly those ranges. It will be used to match the reserved resource ranges when walking through iomem resources.

charset=UTF-8 Content-Transfer-Encoding: 8bit At present, when using the kexec_file_load() syscall to load the kernel image and initramfs, for example: kexec -s -p xxx the kernel does not pass the e820 reserved ranges to the second kernel, which might cause two problems: 1. MMCONFIG: A device in PCI segment 1 cannot be discovered by the kernel PCI probing without all the e820 I/O reservations being present in the e820 table. Which is the case currently, because the kdump kernel does not have those reservations because the kexec command does not pass the I/O reservation via the "memmap=xxx" command line option. Further details courtesy of Bjorn Helgaas¹: I think you should regard correct MCFG/ECAM usage in the kdump kernel as a requirement. MMCONFIG (aka ECAM) space is described in the ACPI MCFG table. If you don't have ECAM: (a) PCI devices won't work at all on non-x86 systems that use only ECAM for config access, (b) you won't be able to access devices on non-0 segments (granted, there aren't very many of these yet, but there will be more in the future), and (c) you won't be able to access extended config space (addresses 0x100-0xfff), which means none of the Extended Capabilities will be available (AER, ACS, ATS, etc). 2. The second issue is that the SME kdump kernel doesn't work without the e820 reserved ranges. When SME is active in the kdump kernel, those reserved regions are still decrypted, but because those reserved ranges are not present at all in kdump kernel's e820 table, they are accessed as encrypted. Which is obviously wrong.

With memory encryption in the picture, special care must be taken when loading a kexec/kdump kernel in a SEV guest. A SEV guest starts and runs fully encrypted. In order to load a kexec kernel and initrd, arch_kexec_post_{alloc,free}_pages() need to not map areas as decrypted unconditionally but differentiate whether the kernel is running as a SEV guest and if so, leave kexec area encrypted.

BF16 is a short version of 32-bit single-precision floating-point format (FP32) and has several advantages over 16-bit half-precision floating-point format (FP16). BF16 keeps FP32 accumulation after multiplication without loss of precision, offers more than enough range for deep learning training tasks, and doesn't need to handle hardware exception. AVX512 BFLOAT16 instructions are enumerated in CPUID.7.1:EAX[bit 5] AVX512_BF16. CPUID.7.1:EAX contains only feature bits. Reuse the currently empty word 12 as a pure features word to hold the feature bits including AVX512_BF16. Detailed information of the CPUID bit and AVX512 BFLOAT16 instructions can be found in the latest Intel Architecture Instruction Set Extensions and Future Features Programming Reference.

This is because the guest may use the local form of the tlb invalidation instruction meaning stale tlb entries would persist where it previously ran. This is handled on guest entry in kvmppc_check_need_tlb_flush() which calls flush_guest_tlb() to perform the tlb flush. Previously the generic radix__local_flush_tlb_lpid_guest() function was used, however the functionality was reimplemented in flush_guest_tlb() to avoid the trace_tlbie() call as the flushing may be done in real mode. The reimplementation in flush_guest_tlb() was missing an erat invalidation after flushing the tlb. This lead to observable memory corruption in the guest due to the caching of stale translations. Fix this by adding the erat invalidation.

For example, if find_first_bit() is provided with an 8 bit bitmap the operation will access BITS_PER_LONG bits from the provided bitmap. While the operation ensures that these extra bits do not affect the result, the memory is still accessed. The capacity bitmasks (CBMs) are typically stored in u32 since they can never exceed 32 bits. A few instances exist where a bitmap_* operation is performed on a CBM by simply pointing the bitmap operation to the stored u32 value. The consequence of this pattern is that some bitmap_* operations will access out-of-bounds memory when interacting with the provided CBM. This same issue has previously been addressed with commit 49e00eee0061 ("x86/intel_rdt: Fix out-of-bounds memory access in CBM tests") but at that time not all instances of the issue were fixed. Fix this by using an unsigned long to store the capacity bitmask data that is passed to bitmap functions.

When not operating in this mode the decrementer behaves as a 32 bit decrementer which is NOT signed extended (as on POWER8). Currently when reading a guest decrementer value we don't take into account whether the large decrementer is enabled or not, and this means the value will be incorrect when the guest is not using the large decrementer.

In the event that the L1 guest tries to run a nested (L2) guest immediately after this and the L2 guest decrementer is negative (which is loaded by L1 before making the H_ENTER_NESTED hcall), then the pending decrementer exception isn't cleared and the L2 entry is blocked since L1 has a pending exception, even though L1 may have already handled the exception and written a positive value for it's decrementer. This results in a loop of L1 trying to enter the L2 guest and L0 blocking the entry since L1 has an interrupt pending with the outcome being that L2 never gets to run and hangs. Fix this by clearing any pending decrementer exceptions when L1 makes the H_ENTER_NESTED hcall since it won't do this if it's decrementer has gone negative, and anyway it's decrementer has been communicated to L0 in the hdec_expires field and L0 will return control to L1 when this goes negative by delivering an H_DECREMENTER exception.

Replace snps,reset-gpio from the ðmac node with reset-gpios in the ethernet-phy node. The old snps,reset-active-low property is now encoded directly as GPIO flag inside the reset-gpios property. snps,reset-delays-us is converted to reset-assert-us and reset-deassert-us. reset-assert-us is the second cell from snps,reset-delays-us while reset-deassert-us was the third cell. Instead of blindly copying the old values (which seems strange since they gave the PHY one second to come out of reset) over this also updates the delays based on the datasheets: - RTL8211F PHY on the Odroid-C1 and MXIII-Plus needs a 10ms assert delay (the datasheet mentions: "For a complete PHY reset, this pin must be asserted low for at least 10ms") and a 30ms deassert delay (the datasheet mentions: "Wait for a further 30ms (for internal circuits settling time) before accessing the PHY register"). The old settings used 10ms for assert and 1000ms for deassert. - IP101GR PHY on the EC-100 and MXQ needs a 10ms assert delay (the datasheet mentions: "Trst | Reset period | 10ms") and a 10ms deassert delay as well (the datasheet mentions: "Tclk_MII_rdy | MII/RMII clock output ready after reset released | 10ms")). The old settings used 10ms for assert and 1000ms for deassert. No functional changes intended.

However, prior, big-endian ARM was relying on gcc to translate its -mbe8 option into ld's --be8 option. Lacking this, ld generated be32 code, making the VDSO generate SIGILL when called by userspace.

It does not. Architectures such as nios2 or h8300 simply take the asm-generic syscall definitions and generate their syscall table from it. Since they don't define __ARCH_WANT_SYS_CLONE the build would fail complaining about sys_clone3 missing. The reason this doesn't happen for legacy clone is that nios2 and h8300 provide assembly stubs for sys_clone. This seems to be done for architectural reasons. The build failures for nios2 and h8300 were caught int -next luckily. The solution is to define __ARCH_WANT_SYS_CLONE3 that architectures can add. Additionally, we need a cond_syscall(clone3) for architectures such as nios2 or h8300 that generate their syscall table in the way I explained above.

Currently, nmi_enter() is done in handle_domain_nmi(), which is much too late as instrumentation code might get called before. Move the nmi_enter/exit() calls to the arch IRQ vector handler. On arm64, it is not possible to know if the IRQ vector handler was called because of an NMI before acknowledging the interrupt. However, It is possible to know whether normal interrupts could be taken in the interrupted context (i.e. if taking an NMI in that context could introduce a potential race condition). When interrupting a context with IRQs disabled, call nmi_enter() as soon as possible. In contexts with IRQs enabled, defer this to the interrupt controller, which is in a better position to know if an interrupt taken is an NMI.

This resulted in local_irq_restore() potentially modifying the value of PMR in undesired location due to the state of PSR.I upon flag saving [1]. In an attempt to solve this issue in a less hackish manner, introduce a bit (GIC_PRIO_IGNORE_PMR) for the PMR values that can represent whether PSR.I is being used to disable interrupts, in which case it takes precedence of the status of interrupt masking via PMR. GIC_PRIO_PSR_I_SET is chosen such that ( | GIC_PRIO_PSR_I_SET) does not mask more interrupts than as some sections (e.g. arch_cpu_idle(), interrupt acknowledge path) requires PMR not to mask interrupts that could be signaled to the CPU when using only PSR.I.

This creates a path through vclock_gettime() in which no vclock is enabled at all (due to disabled TSC on old CPUs, for example) but the pvclock or hvclock page nevertheless read. This will segfault on bare metal. This fixes commit 459e3a21535a ("gcc-9: properly declare the {pv,hv}clock_page storage") in the sense that, before that commit, GCC didn't seem to generate the offending code. There was nothing wrong with that commit per se, and -stable maintainers should backport this to all supported kernels regardless of whether the offending commit was present, since the same crash could just as easily be triggered by the phase of the moon. On GCC 9.1.1, this doesn't seem to affect the generated code at all, so I'm not too concerned about performance regressions from this fix.

This behavior is not correct as the selector should be preserved. Update only the base value and leave the selector intact. To simplify the code further remove the conditional checking for the same value as this code is not performance critical. The only recognizable downside of this change is when the selector is already nonzero on write. The base will be reloaded according to the selector. But the case is highly unexpected in real usages.

That allows to accelerate certain FS/GS base operations in subsequent changes. Note, that while possible, the user space entry/exit GSBASE operations are not going to use the new FSGSBASE instructions. The reason is that it would require additional storage for the user space value which adds more complexity to the low level code and experiments have shown marginal benefit. This may be revisited later but for now the SWAPGS based handling in the entry code is preserved except for the paranoid entry/exit code. To preserve the SWAPGS entry mechanism introduce __[rd|wr]gsbase_inactive() helpers. Note, for Xen PV, paravirt hooks can be added later as they might allow a very efficient but different implementation. [ tglx: Massaged changelog ] Signed-off-by: Chang S.

Use that capability to preserve the full state. This will enable user code to do whatever it wants with the new instructions without any kernel-induced gotchas. (There can still be architectural gotchas: movl %gs,%eax; movl %eax,%gs may change GSBASE if WRGSBASE was used, but users are expected to read the CPU manual before doing things like that.) This is a considerable speedup. It seems to save about 100 cycles per context switch compared to the baseline 4.6-rc1 behavior on a Skylake laptop.

But when GSBASE is unknown, the per-CPU base can be found from the per_cpu_offset table with a CPU NR. The CPU NR is extracted from the limit field of the CPUNODE entry in GDT, or by the RDPID instruction. This is a prerequisite for using FSGSBASE in the low level entry code. Also, add the GAS-compatible RDPID macro as binutils 2.21 do not support it. Support is added in version 2.27. [ tglx: Massaged changelog ] Suggested-by: H. Peter Anvin Signed-off-by: Chang S.

Bae" Date: Wed, 8 May 2019 03:02:27 -0700 Subject: x86/entry/64: Handle FSGSBASE enabled paranoid entry/exit Without FSGSBASE, user space cannot change GSBASE other than through a PRCTL. The kernel enforces that the user space GSBASE value is postive as negative values are used for detecting the kernel space GSBASE value in the paranoid entry code. If FSGSBASE is enabled, user space can set arbitrary GSBASE values without kernel intervention, including negative ones, which breaks the paranoid entry assumptions. To avoid this, paranoid entry needs to unconditionally save the current GSBASE value independent of the interrupted context, retrieve and write the kernel GSBASE and unconditionally restore the saved value on exit. The restore happens either in paranoid_exit or in the special exit path of the NMI low level code. All other entry code pathes which use unconditional SWAPGS are not affected as they do not depend on the actual content. [ tglx: Massaged changelogs and comments ] Suggested-by: H.

So, the application needs to know if it can safely use these instructions. Just looking at the CPUID bit is not enough because it may be running in a kernel that does not enable the instructions. One way for the application would be to just try and catch the SIGILL. But that is difficult to do in libraries which may not want to overwrite the signal handlers of the main application. Enumerate the enabled FSGSBASE capability in bit 1 of AT_HWCAP2 in the ELF aux vector. AT_HWCAP2 is already used by PPC for similar purposes. The application can access it open coded or by using the getauxval() function in newer versions of glibc. [ tglx: Massaged changelog ] Signed-off-by: Andi Kleen Signed-off-by: Chang S.

Direct calls of this form can be mitigate by pinning bits of CR4 so that they cannot be changed through a common function. This is not intended to be a general ROP protection (which would require CFI to defend against properly), but rather a way to avoid trivial direct function calling (or CFI bypasses via a matching function prototype) as seen in: https://googleprojectzero.blogspot.com/2017/05/exploiting-linux-kernel-via-packet.html (https://github.com/xairy/kernel-exploits/tree/master/CVE-2017-7308) The goals of this change: - Pin specific bits (SMEP, SMAP, and UMIP) when writing CR4. - Avoid setting the bits too early (they must become pinned only after CPU feature detection and selection has finished). - Pinning mask needs to be read-only during normal runtime. - Pinning needs to be checked after write to validate the cr4 state Using __ro_after_init on the mask is done so it can't be first disabled with a malicious write. Since these bits are global state (once established by the boot CPU and kernel boot parameters), they are safe to write to secondary CPUs before those CPUs have finished feature detection. As such, the bits are set at the first cr4 write, so that cr4 write bugs can be detected (instead of silently papered over). This uses a few bytes less storage of a location we don't have: read-only per-CPU data. A check is performed after the register write because an attack could just skip directly to the register write. Such a direct jump is possible because of how this function may be built by the compiler (especially due to the removal of frame pointers) where it doesn't add a stack frame (function exit may only be a retq without pops) which is sufficient for trivial exploitation like in the timer overwrites mentioned above). The asm argument constraints gain the "+" modifier to convince the compiler that it shouldn't make ordering assumptions about the arguments or memory, and treat them as changed.

Many applications read /proc/cpuinfo at the start for trivial reasons like counting cores or detecting cpu features. While sensitive workloads like DPDK network polling don't like any interrupts. Integrates this feature with cpu isolation and do not send IPIs to CPUs without housekeeping flag HK_FLAG_MISC (set by nohz_full). Code that requests cpu frequency like show_cpuinfo() falls back to the last frequency set by the cpufreq driver if this method returns 0.

From 98cd3c3f83fbba27a6bacd75ad12e8388a61a32a Mon Sep 17 00:00:00 2001 From: Peter Collingbourne Date: Fri, 21 Jun 2019 10:52:32 +0100 Subject: arm64: vdso: Build vDSO with -ffixed-x18 The vDSO needs to be built with x18 reserved in order to accommodate userspace platform ABIs built on top of Linux that use the register to carry inter-procedural state, as provided for by the AAPCS. An example of such a platform ABI is the one that will be used by an upcoming version of Android. Although this change is currently a no-op due to the fact that the vDSO is currently implemented in pure assembly on arm64, it is necessary in order to prepare for using the generic C implementation of the vDSO.

The address range is determined by using CPUID.0x5. A store to an address within the specified address range triggers the monitoring hardware to wake up the processor waiting in umwait. umwait instructs the processor to enter an implementation-dependent optimized state while monitoring a range of addresses. The optimized state may be either a light-weight power/performance optimized state (C0.1 state) or an improved power/performance optimized state (C0.2 state). tpause instructs the processor to enter an implementation-dependent optimized state C0.1 or C0.2 state and wake up when time-stamp counter reaches specified timeout. The three instructions may be executed at any privilege level. The instructions provide power saving method while waiting in user space. Additionally, they can allow a sibling hyperthread to make faster progress while this thread is waiting. One example of an application usage of umwait is when waiting for input data from another application, such as a user level multi-threaded packet processing engine.

IA32_UMWAIT_CONTROL MSR register allows the OS to enable/disable C0.2 on the processor and to set the maximum time the processor can reside in C0.1 or C0.2. By default C0.2 is enabled so the user wait instructions can enter the C0.2 state to save more power with slower wakeup time. Andy Lutomirski proposed to set the maximum umwait time to 100000 cycles by default. A quote from Andy: "What I want to avoid is the case where it works dramatically differently on NO_HZ_FULL systems as compared to everything else. Also, UMWAIT may behave a bit differently if the max timeout is hit, and I'd like that path to get exercised widely by making it happen even on default configs." A sysfs interface to adjust the time and the C0.2 enablement is provided in a follow up change. [ tglx: Renamed MSR_IA32_UMWAIT_CONTROL_MAX_TIME to MSR_IA32_UMWAIT_CONTROL_TIME_MASK because the constant is used as mask throughout the code.

By default, C0.2 is enabled and the user wait instructions results in lower power consumption with slower wakeup time. But in real time systems which require faster wakeup time although power savings could be smaller, the administrator needs to disable C0.2 and all umwait invocations from user applications use C0.1. Create a sysfs interface which allows the administrator to control C0.2 state during run time. Andy Lutomirski suggested to turn off local irqs before writing the MSR to ensure the cached control value is not changed by a concurrent sysfs write from a different CPU via IPI. [ tglx: Simplified the update logic in the write function and got rid of all the convoluted type casts. Added a shared update function and made the namespace consistent.

If that qualifier is also used in the bus_find_device() prototype, it will be possible to pass the same match() callback function to both bus_find_device() and class_find_device(), which will allow some optimizations to be made in order to avoid code duplication going forward. Also with that, constify the "data" parameter as it is passed as a const to the match function. For this reason, change the prototype of bus_find_device() to match the prototype of class_find_device() and adjust its callers to use the const qualifier in accordance with the new prototype of it.

The case depends on the baseboard so muxing the data lanes is not part of this patch. - SMARC I2S - SMARC Watchdog Note: The watchdog output pin is routed to the CPLD and the SMARC header.

The LDO10 (PVDD_PRE_1V8) supplies instead VDDP_MMC pin of eMMC host interface and it is already marked as always on. This change only properly models the hardware and reflects in usage of regulators. There is no functional change because: 1. LDO18 cannot be turned off (e.g. by lack of consumers) because in off mode it is controlled by LDO18EN pin, which is pulled up by always-on regulator LDO2 (PVDD_APIO_1V8). 2. LDO10 is marked as always on so removing its consumer will not have effect.

User defines following struct for each MSR register: struct perf_msr { u64 msr; struct attribute_group *grp; bool (*test)(int idx, void *data); bool no_check; }; Where: msr - is the MSR address attrs - is attribute groups array to add if the check passed test - is test function pointer no_check - is bool that bypass the check and adds the attribute without any test The array of struct perf_msr is passed into: perf_msr_probe(struct perf_msr *msr, int cnt, bool zero, void *data) Together with: cnt - which is the number of struct msr array elements data - which is user pointer passed to the test function zero - allow counters that returns zero on rdmsr The perf_msr_probe will executed test code, read the MSR and check the value is != 0. If all these tests pass, related attribute group is kept visible. Also adding PMU_EVENT_GROUP macro helper to define attribute group for single attribute. It will be used in following patches.

While at current asm/io.h the accessors are defined, their implementation is only applicable either for 64bit systems, or for systems with cpu_has_64bits flag set. Obviously there are MIPS systems which are neither of these, but still need to have those drivers supported. In this case the solution is to define some generic versions of the q-accessors, but with a limitation to be non-atomic. Such accessors are defined in the io-64-nonatomic-{hi-lo,lo-hi}.h file. The drivers which utilize the q-suffixed IO-methods are supposed to include the header file, so in case if these accessors aren't defined for the platform, the generic non-atomic versions are utilized. Currently the MIPS-specific asm/io.h file provides the q-accessors for any MIPS system even for ones, which in fact don't support them and raise BUG() in case if any of them is called. Due to this the generic versions of the accessors are never used while an attempt to call the IO-methods causes the kernel BUG(). In order to fix this we need to define the q-accessors only for the MIPS systems, which actually support them, and don't define them otherwise, so to let the corresponding drivers to use the non-atomic q-suffixed accessors.

The IRQ signal is routed to both of them and user can chose which ICU will resend the IRQ to their respective VPE. The patch adds the support for the second ICU. The patch changes a register definition of the driver. Instead of an individual IM, the whole ICU is defined. This will only affects openwrt patched kernel (vanilla doesn't have additional .dts files). Also spinlocks has been added, both cores can RMW different bitfields in the same register. Added affinity set function. The new VPE cpumask will take into the action at the irq enable. The functionality was tested on 4.14 openwrt kernel and TP-W9980B modem.

The missed 'set -e' is a typical bug in shell scripting. For example, when a disk space shortage occurs while this script is running, it actually ends up with generating a truncated capflags.c. Yet, mkcapflags.sh continues running and exits with 0. So, the build system assumes it has succeeded. It will not be re-generated in the next invocation of Make since its timestamp is newer than that of any of the source files. Add 'set -e' so that any error in this script is caught and propagated to the build system. Since 9c2af1c7377a ("kbuild: add .DELETE_ON_ERROR special target"), make automatically deletes the target on any failure. So, the broken capflags.c will be deleted automatically.

is unnecessary. Worse, the windup does not restore AMR, so this can result in a false KUAP fault after a recoverable machine check hits inside a user copy operation. Fix this similarly to HMI by just avoiding the kuap lock in the early machine check handler (it will be set by the late handler that runs in virtual mode if that runs). If the virtual mode handler is reached, it will lock and restore the AMR.

Update DT for it. In the new binding, the number of connected chips are described in DT instead of run-time probed. I added just one chip to the reference boards, where we do not know if the on-board NAND device is a single chip or multiple chips. If we added too many chips into DT, it would end up with the timeout error in nand_scan_ident(). I changed all the pinctrl properties to use the single CS.

This issue was tracked down to the case when the kernel image unpacks in a way that it crosses an 1G boundary. The crash is caused by an overrun of the PMD page table in __startup_64() and corruption of P4D page table allocated next to it. This particular issue is not visible with 4-level paging as P4D page tables are not used. But the P4D and the PUD calculation have similar problems. The PMD index calculation is wrong due to operator precedence, which fails to confine the PMDs in the PMD array on wrap around. The P4D calculation for 5-level paging and the PUD calculation calculate the first index correctly, but then blindly increment it which causes the same issue when a kernel image is located across a 512G and for 5-level paging across a 46T boundary. This wrap around mishandling was introduced when these parts moved from assembly to C. Restore it to the correct behaviour.

But now only PUD_SIZE alignment is guaranteed. In the case I was able to reproduce the following vaddr/paddr values were observed in phys_p4d_init(): Iteration vaddr paddr 1 0xff4228027fe00000 0x033fe00000 2 0xff42287f40000000 0x8000000000 'vaddr' in both cases belongs to the same p4d entry. But due to the original assumption that PAGE_OFFSET is aligned to P4D_SIZE this overlap cannot be handled correctly. The code assumes strictly aligned entries and unconditionally increments the index into the P4D table, which creates false duplicate entries. Once the index reaches the end, the last entry in the page table is missing. Aside of that the 'paddr >= paddr_end' condition can evaluate wrong which causes an P4D entry to be cleared incorrectly. Change the loop in phys_p4d_init() to walk purely based on virtual addresses like __kernel_physical_mapping_init() does. This makes it work correctly with unaligned virtual addresses.

The reason for this is that putting modules in the vmalloc region (like we normally do when KASLR is enabled) is not possible in this case, given that the entire vmalloc region is already backed by KASAN zero shadow pages, and so allocating dedicated KASAN shadow space as required by loaded modules is not possible. The default module allocation window is set to [_etext - 128MB, _etext] in kaslr.c, which is appropriate for KASLR kernels booted without a seed or with 'nokaslr' on the command line. However, as it turns out, it is not quite correct for the KASAN case, since it still intersects the vmalloc region at the top, where attempts to allocate shadow pages will collide with the KASAN zero shadow pages, causing a WARN() and all kinds of other trouble. So cap the top end to MODULES_END explicitly when running with KASAN.

Which is true for any valid x86 VDSO clocksource. Stupidly it still did the mask operation for no reason and at the wrong place right after reading the clocksource. 2) It contains a sanity check to catch the case where slightly unsynchronized TSC values can be observed which would cause the delta calculation to make a huge jump. It therefore checks whether the current TSC value is larger than the value on which the current conversion is based on. If it's not larger the base value is used to prevent time jumps. #1 Is not only stupid for the X86 case because it does the masking for no reason it is also completely wrong for clocksources with a smaller mask which can legitimately wrap around during a conversion period. The core timekeeping code does it correct by applying the mask after the delta calculation: (now - base) & mask #2 is equally broken for clocksources which have smaller masks and can wrap around during a conversion period because there the now > base check is just wrong and causes stale time stamps and time going backwards issues. Unbreak it by: 1) Removing the mask operation from the clocksource read which makes the fallback detection work for all clocksources 2) Replacing the conditional delta calculation with a overrideable inline function. #2 could reuse clocksource_delta() from the timekeeping code but that results in a significant performance hit for the x86 VSDO. The timekeeping core code must have the non optimized version as it has to operate correctly with clocksources which have smaller masks as well to handle the case where TSC is discarded as timekeeper clocksource and replaced by HPET or pmtimer. For the VDSO there is no replacement clocksource. If TSC is unusable the syscall is enforced which does the right thing. To accommodate to the needs of various architectures provide an override-able inline function which defaults to the regular delta calculation with masking: (now - base) & mask Override it for x86 with the non-masking and checking version. This unbreaks the ARM64 syscall fallback operation, allows to use clocksources with arbitrary width and preserves the performance optimization for x86.

In the case of SSBD, unless the host has enabled SSBD always on mode (by passing "spec_store_bypass_disable=on" in the kernel parameters), the SSBD bit is not set in the mask and the guest can not properly enable the SSBD always on mitigation mode. This has been confirmed by running the SSBD PoC on a guest using the SSBD always on mitigation mode (booted with kernel parameter "spec_store_bypass_disable=on"), and verifying that the guest is vulnerable unless the host is also using SSBD always on mode. In addition, the guest OS incorrectly reports the SSB vulnerability as mitigated. Always set the SSBD bit in x86_spec_ctrl_mask when the host CPU supports it, allowing the guest to use SSBD whether or not the host has chosen to enable the mitigation in any of its modes.

Specifically the LPM driver that the Broadcom Bluetooth expects to have (but is missing in mainline) has two halves of the equation: BT_HOST_WAKE and BT_DEV_WAKE. The BT_HOST_WAKE (which was handled in the previous commit) is the one that lets the Bluetooth wake the system up. The BT_DEV_WAKE (this patch) tells the Bluetooth that it's OK to go into a low power mode. That means we were burning a bit of extra power in S3 without this patch. Measurements are a bit noisy, but it appears to be a few mA worth of difference. NOTE: Though these pins don't do much on systems with Marvell Bluetooth, downstream kernels set it on all veyron boards so we'll do the same.

Currently the rk3328-roc-cc ethernet is enabled using "snps,force_thresh_dma_mode". While this works, the performance leaves a lot to be desired. A previous attempt to improve performance used "snps,txpbl = <0x4>". This also allowed networking to function, but performance varied between boards. This patch takes that one step further. Set txpbl and rxpbl to 0x4. This can also be accomplished with "snps,pbl =<0x4>" which affects both. Also set "snps,aal" which forces address aligned DMA mode.

As explained in the binding, those clocks are required for new platforms but not for existing platforms before commit fe8abf332b8f ("usb: dwc3: support clocks and resets for DWC3 core"). However, as those clocks are really treated as required, this ends with having some annoying messages when the "rockchip,rk3399-dwc3" is used: [ 1.724107] dwc3 fe800000.dwc3: Failed to get clk 'ref': -2 [ 1.731893] dwc3 fe900000.dwc3: Failed to get clk 'ref': -2 [ 2.495937] dwc3 fe800000.dwc3: Failed to get clk 'ref': -2 [ 2.647239] dwc3 fe900000.dwc3: Failed to get clk 'ref': -2 In order to remove those annoying messages, update the DWC3 hardware module node and add all the required clocks. With this change, both, the glue node and the DWC3 core node, have the clocks defined, but that's not really a problem and there isn't a side effect on do this. So, we can get rid of the annoying get clk error messages.

This is required because certain dynamic binary instrumentation tools attempt to read the call targets of call instructions in the instrumented code. If the instrumented code uses vsyscalls, then the vsyscall page needs to contain readable code. Unfortunately, leaving readable memory at a deterministic address can be used to help various ASLR bypasses, so some hardening value can be gained by disallowing vsyscall reads. Given how rarely the vsyscall page needs to be readable, add a mechanism to make the vsyscall page be execute only.

The information is scattered in different data structures. Also the HPET reservation in the HPET character device is split out into several places which makes the code hard to follow. Assigning a mode to the channel allows to consolidate the reservation code and paves the way for further simplifications. As a first step set the mode of the legacy channels when the HPET is in legacy mode.

This comes with a twist. The static clockevent initializer has selected support for periodic and oneshot mode unconditionally whether the HPET config advertised periodic mode or not. Even the pre clockevents code did this. But.... Using the conditional in hpet_init_clockevent() makes at least Qemu and one hardware machine fail to boot. There are two issues which cause the boot failure: #1 After the timer delivery test in IOAPIC and the IOAPIC setup the next interrupt is not delivered despite the HPET channel being programmed correctly. Reprogramming the HPET after switching to IOAPIC makes it work again. After fixing this, the next issue surfaces: #2 Due to the unconditional periodic mode 'availability' the Local APIC timer calibration can hijack the global clockevents event handler without causing damage. Using oneshot at this stage makes if hang because the HPET does not get reprogrammed due to the handler hijacking. Duh, stupid me! Both issues require major surgery and especially the kick HPET again after enabling IOAPIC results in really nasty hackery. This 'assume periodic works' magic has survived since HPET support got added, so it's questionable whether this should be fixed. Both Qemu and the failing hardware machine support periodic mode despite the fact that both don't advertise it in the configuration register and both need that extra kick after switching to IOAPIC.

This flexibility brings several issues to kexec/kdump: 1) Dynamic switching between paging modes requires support in the target kernel. This means kexec from a 5-level paging kernel into a kernel which does not support mode switching is not possible. So the loader needs to be able to analyze the supported paging modes of the kexec target kernel. 2) If running on a 5-level paging kernel and the kexec target kernel is a 4-level paging kernel, the target immage cannot be loaded above the 64TB address space limit. But the kexec loader searches for a load area from top to bottom which would eventually put the target kernel above 64TB when the machine has large enough RAM size. So the loader needs to be able to analyze the paging mode of the target kernel to load it at a suitable spot in the address space. Solution: Add two bits XLF_5LEVEL and XLF_5LEVEL_ENABLED: - Bit XLF_5LEVEL indicates whether 5-level paging mode switching support is available. (Issue #1) - Bit XLF_5LEVEL_ENABLED indicates whether the kernel was compiled with full 5-level paging support (CONFIG_X86_5LEVEL=y). (Issue #2) The loader will use these bits to verify whether the target kernel is suitable to be kexec'ed to from a 5-level paging kernel and to determine the constraints of the target kernel load address. The flags will be used by the kernel kexec subsystem and the userspace kexec tools. [ tglx: Massaged changelog ] Signed-off-by: Baoquan He Signed-off-by: Thomas Gleixner Acked-by: Kirill A.

The 1st kernel reserves the kdump kernel region during bootup. At that point it is not known whether the kdump kernel has 5-level or 4-level paging support.

Furthermore, all processors must program these registers in lock step and with interrupts disabled; the process also involves flushing caches and TLBs twice. As a result, the process may take a considerable amount of time. On some platforms, this can lead to a large skew of the refined-jiffies clock source. Early when booting, if no other clock is available (e.g., booting with hpet=disabled), the refined-jiffies clock source is used to monitor the TSC clock source. If the skew of refined-jiffies is too large, Linux wrongly assumes that the TSC is unstable: clocksource: timekeeping watchdog on CPU1: Marking clocksource 'tsc-early' as unstable because the skew is too large: clocksource: 'refined-jiffies' wd_now: fffedc10 wd_last: fffedb90 mask: ffffffff clocksource: 'tsc-early' cs_now: 5eccfddebc cs_last: 5e7e3303d4 mask: ffffffffffffffff tsc: Marking TSC unstable due to clocksource watchdog As per measurements, around 98% of the time needed by the procedure to program MTRRs in multi-processor systems is spent flushing caches with wbinvd(). As per the Section 11.11.8 of the Intel 64 and IA 32 Architectures Software Developer's Manual, it is not necessary to flush caches if the CPU supports cache self-snooping. Thus, skipping the cache flushes can reduce by several tens of milliseconds the time needed to complete the programming of the MTRR registers: Platform Before After 104-core (208 Threads) Skylake 1437ms 28ms 2-core ( 4 Threads) Haswell 114ms 2ms Reported-by: Mohammad Etemadi Signed-off-by: Ricardo Neri Signed-off-by: Thomas Gleixner Cc: Borislav Petkov Cc: Alan Cox Cc: Tony Luck Cc: "H.

Many locks are involved. To be on the safe side, text_mutex must become a low level lock taken after cpu_hotplug_lock.rw_sem. This can't be achieved easily with the current ftrace design. For example, arm calls set_all_modules_text_rw() already in ftrace_arch_code_modify_prepare(), see arch/arm/kernel/ftrace.c. This functions is called: + outside stop_machine() from ftrace_run_update_code() + without stop_machine() from ftrace_module_enable() Fortunately, the problematic fix is needed only on x86_64. It is the only architecture that calls set_all_modules_text_rw() in ftrace path and supports livepatching at the same time. Therefore it is enough to move text_mutex handling from the generic kernel/trace/ftrace.c into arch/x86/kernel/ftrace.c: ftrace_arch_code_modify_prepare() ftrace_arch_code_modify_post_process() This patch basically reverts the ftrace part of the problematic commit 9f255b632bf12c4dd7 ("module: Fix livepatch/ftrace module text permissions race"). And provides x86_64 specific-fix. Some refactoring of the ftrace code will be needed when livepatching is implemented for arm or nds32. These architectures call set_all_modules_text_rw() and use stop_machine() at the same time.

When gated, the 8254 registers can still be programmed as normal, but there are no IRQ0 timer interrupts. Some products such as the Connex L1430 and exone go Rugged E11 use this register to ship with the PIT gated by default. This causes Linux to fail to boot: Kernel panic - not syncing: IO-APIC + timer doesn't work! Boot with apic=debug and send a report. The panic happens before the framebuffer is initialized, so to the user, it appears as an early boot hang on a black screen. Affected products typically have a BIOS option that can be used to enable the 8254 and make Linux work (Chipset -> South Cluster Configuration -> Miscellaneous Configuration -> 8254 Clock Gating), however it would be best to make Linux support the no-8254 case. Modern sytems allow to discover the TSC and local APIC timer frequencies, so the calibration against the PIT is not required. These systems have always running timers and the local APIC timer works also in deep power states. So the setup of the PIT including the IO-APIC timer interrupt delivery checks are a pointless exercise. Skip the PIT setup and the IO-APIC timer interrupt checks on these systems, which avoids the panic caused by non ticking PITs and also speeds up the boot process. Thanks to Daniel for providing the changelog, initial analysis of the problem and testing against a variety of machines.

So if we have threads offline, we have to temporarily bring them up. This can race with administrator actions such as SMT state changes. As of dfd718a2ed1f ("powerpc/rtas: Fix a potential race between CPU-Offline & Migration"), rtas_ibm_suspend_me() accounts for this, but errors out with -EBUSY for what almost certainly is a transient condition in any reasonable scenario. Callers of rtas_ibm_suspend_me() already retry when -EAGAIN is returned, and it is typical during a migration for that to happen repeatedly for several minutes polling the H_VASI_STATE hcall result before proceeding to the next stage. So return -EAGAIN instead of -EBUSY when this race is encountered. Additionally: logging this event is still appropriate but use pr_info instead of pr_err; and remove use of unlikely() while here as this is not a hot path at all.

Rao" Date: Thu, 27 Jun 2019 15:29:40 +0530 Subject: powerpc/xmon: Fix disabling tracing while in xmon Commit ed49f7fd6438d ("powerpc/xmon: Disable tracing when entering xmon") added code to disable recording trace entries while in xmon. The commit introduced a variable 'tracing_enabled' to record if tracing was enabled on xmon entry, and used this to conditionally enable tracing during exit from xmon. However, we are not checking the value of 'fromipi' variable in xmon_core() when setting 'tracing_enabled'. Due to this, when secondary cpus enter xmon, they will see tracing as being disabled already and tracing won't be re-enabled on exit. Fix the same.

Also add a comment where the existing behavior seems to be lacking. Switching to the generic code enables DMA allocations from atomic context, which is required by the DMA API documentation, and also adds various other minor features drivers start relying upon. It also makes sure we have a tested code base for all architectures that require uncached pte bits for coherent DMA allocations.

So even though the contention reduction is NOT super high, it is still an improvement. There's an additional code size improvement as we only have 2 up_read() calls now. Note to myself: -------------- 1. Given the way it is done, we are forced to move @bad_area label earlier causing the various "goto bad_area" cases to hit perf stat code. - PERF_COUNT_SW_PAGE_FAULTS is NOW updated for access errors which is what arm/arm64 seem to be doing as well (with slightly different code) - PERF_COUNT_SW_PAGE_FAULTS_{MAJ,MIN} must NOT be updated for the error case which is guarded by now setting @fault initial value to VM_FAULT_ERROR which serves both cases when handle_mm_fault() returns error or is not called at all. 2. arm/arm64 use two homebrew fault flags VM_FAULT_BAD{MAP,MAPACCESS} which I was inclined to add too but seems not needed for ARC - given that we have everything is 1 function we can still use goto - we setup si_code at the right place (arm* do that in the end) - we init fault already to error value which guards entry into perf stats event update Cc: Peter Zijlstra Signed-off-by: Vineet Gupta --- arch/arc/mm/fault.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'arch') diff --git a/arch/arc/mm/fault.c b/arch/arc/mm/fault.c index 6a78a2d776a9..e7df5ef3877a 100644 --- a/arch/arc/mm/fault.c +++ b/arch/arc/mm/fault.c @@ -152,6 +152,9 @@ retry: } } +bad_area: + up_read(&mm->mmap_sem); + /* * Major/minor page fault accounting * (in case of retry we only land here once) @@ -170,13 +173,9 @@ retry: } /* Normal return path: fault Handled Gracefully */ - up_read(&mm->mmap_sem); return; } -bad_area: - up_read(&mm->mmap_sem); - if (!user_mode(regs)) goto no_context; -- cgit v1.2.3 From 45869eb0c0afd72bd5ab2437d4b00915697c044a Mon Sep 17 00:00:00 2001 From: Vineet Gupta Date: Tue, 9 Apr 2019 16:55:15 -0700 Subject: ARCv2: entry: comments about hardware auto-save on taken interrupts Signed-off-by: Vineet Gupta --- arch/arc/include/asm/entry-arcv2.h | 78 ++++++++++++++++++++++++++++++-------- 1 file changed, 62 insertions(+), 16 deletions(-) (limited to 'arch') diff --git a/arch/arc/include/asm/entry-arcv2.h b/arch/arc/include/asm/entry-arcv2.h index 225e7df2d8ed..1c3520d1fa42 100644 --- a/arch/arc/include/asm/entry-arcv2.h +++ b/arch/arc/include/asm/entry-arcv2.h @@ -7,15 +7,54 @@ #include #include /* For THREAD_SIZE */ +/* + * Interrupt/Exception stack layout (pt_regs) for ARCv2 + * (End of struct aligned to end of page [unless nested]) + * + * INTERRUPT EXCEPTION + * + * manual --------------------- manual + * | orig_r0 | + * | event/ECR | + * | bta | + * | user_r25 | + * | gp | + * | fp | + * | sp | + * | r12 | + * | r30 | + * | r58 | + * | r59 | + * hw autosave --------------------- + * optional | r0 | + * | r1 | + * ~ ~ + * | r9 | + * | r10 | + * | r11 | + * | blink | + * | lpe | + * | lps | + * | lpc | + * | ei base | + * | ldi base | + * | jli base | + * --------------------- + * hw autosave | pc / eret | + * mandatory | stat32 / erstatus | + * --------------------- + */ + /*------------------------------------------------------------------------*/ .macro INTERRUPT_PROLOGUE called_from - - ; Before jumping to Interrupt Vector, hardware micro-ops did following: + ; (A) Before jumping to Interrupt Vector, hardware micro-ops did following: ; 1.

This helps shave a few instructions from EXCEPTION_PROLOGUE by eliding re-reading ERSTATUS and some bit fiddling. However TLB Miss Exception handler can clobber the CPU flags and still end up in EXCEPTION_PROLOGUE in the slow path handling TLB handling case: EV_TLBMissD do_slow_path_pf EV_TLBProtV (aliased to call_do_page_fault) EXCEPTION_PROLOGUE As a result, EXCEPTION_PROLOGUE need to "unclobber" the Z flag which this patch changes. It is now pushed out to TLB Miss Exception handler. The reasons beings: - The flag restoration is only needed for slowpath TLB Miss Exception handling, but currently being in EXCEPTION_PROLOGUE penalizes all exceptions such as ProtV and syscall Trap, where Z flag is already as expected. - Pushing unclobber out to where it was clobbered is much cleaner and also serves to document the fact. - Makes EXCEPTION_PROLGUE similar to INTERRUPT_PROLOGUE so easier to refactor the common parts which is what this series aims to do Signed-off-by: Vineet Gupta --- arch/arc/include/asm/entry-arcv2.h | 8 -------- arch/arc/mm/tlbex.S | 11 +++++++++++ 2 files changed, 11 insertions(+), 8 deletions(-) (limited to 'arch') diff --git a/arch/arc/include/asm/entry-arcv2.h b/arch/arc/include/asm/entry-arcv2.h index 1c3520d1fa42..3209a6762960 100644 --- a/arch/arc/include/asm/entry-arcv2.h +++ b/arch/arc/include/asm/entry-arcv2.h @@ -225,14 +225,6 @@ ; -- for interrupts, regs above are auto-saved by h/w in that order -- ; Now do what ISR prologue does (manually save r12, sp, fp, gp, r25) - ; - ; Set Z flag if this was from U mode (expected by INTERRUPT_PROLOGUE) - ; Although H/w exception micro-ops do set Z flag for U mode (just like - ; for interrupts), it could get clobbered in case we soft land here from - ; a TLB Miss exception handler (tlbex.S) - - and r10, r10, STATUS_U_MASK - xor.f 0, r10, STATUS_U_MASK INTERRUPT_PROLOGUE exception diff --git a/arch/arc/mm/tlbex.S b/arch/arc/mm/tlbex.S index 471a97bf492d..c55d95dd2f39 100644 --- a/arch/arc/mm/tlbex.S +++ b/arch/arc/mm/tlbex.S @@ -393,6 +393,17 @@ EV_TLBMissD_fast_ret: ; additional label for VDK OS-kit instrumentation ;-------- Common routine to call Linux Page Fault Handler ----------- do_slow_path_pf: +#ifdef CONFIG_ISA_ARCV2 + ; Set Z flag if exception in U mode.

This patch removes "pmu" interrupt for Exynos4210 SoCs, so the driver will skip the PMU module.

Both of the above options are enabled by default for architectures such as x86, ARM, and ARM64. The idle dynamic ticks helps use save power by stopping timer ticks when the system is idle whereas hrtimers is a much improved timer subsystem compared to the old "timer wheel" based system.

Doing it in the opposite order crashes if the exception came from a context with user GSBASE and user CR3 -- RESTORE_CR3 cannot resture user CR3 if run with user GSBASE. This results in infinitely recursing exceptions if user code does SYSENTER with TF set if both FSGSBASE and PTI are enabled. The old code worked if user code just set TF without SYSENTER because #DB from user mode is special cased in idtentry and paranoid_exit doesn't run. Fix it by cleaning up the spaghetti code. All that paranoid_exit needs to do is to disable IRQs, handle IRQ tracing, then restore CR3, and restore GSBASE. Simply do those actions in that order.

For performance it is taken in the common case, which is a fetch bubble and a waste of i-cache. For code development and maintainence, it requires yet another stack frame setup routine, and that constrains all exception handlers to follow the same register save pattern which inhibits future optimisation. Remove the test/branch and replace it with a trap. Teach the program check handler to use the emergency stack for this case. This does not result in quite so nice a message, however the SRR0 and SRR1 of the crashed interrupt can be seen in r11 and r12, as is the original r1 (adjusted by INT_FRAME_SIZE). These are the most important parts to debugging the issue. The original r9-12 and cr0 is lost, which is the main downside. kernel BUG at linux/arch/powerpc/kernel/exceptions-64s.S:847!

First of all we do not want to change existing behavior when intercepting AP instructions without the SIE allowing the guest to use AP instructions. In this patch we only handle the AQIC interception allowed by facility 65 which will be enabled when the complete interception infrastructure will be present. We add a callback inside the KVM arch structure for s390 for a VFIO driver to handle a specific response to the PQAP instruction with the AQIC command and only this command. But we want to be able to return a correct answer to the guest even there is no VFIO AP driver in the kernel. Therefor, we inject the correct exceptions from inside KVM for the case the callback is not initialized, which happens when the vfio_ap driver is not loaded. We do consider the responsibility of the driver to always initialize the PQAP callback if it defines queues by initializing the CRYCB for a guest. If the callback has been setup we call it. If not we setup an answer considering that no queue is available for the guest when no callback has been setup.

It is, however, wrong to assume that it is only valid to do VMCLEAR for the eVMCS which is currently active on the vCPU performing VMCLEAR. Currently, the logic in handle_vmclear() is broken: in case, there is no active eVMCS on the vCPU doing VMCLEAR we treat the argument as a 'normal' VMCS and kvm_vcpu_write_guest() to the 'launch_state' field irreversibly corrupts the memory area. So, in case the VMCLEAR argument is not the current active eVMCS on the vCPU, how can we know if the area it is pointing to is a normal or an enlightened VMCS? Thanks to the bug in Hyper-V (see commit 72aeb60c52bf7 ("KVM: nVMX: Verify eVMCS revision id match supported eVMCS version on eVMCS VMPTRLD")) we can not, the revision can't be used to distinguish between them. So let's assume it is always enlightened in case enlightened vmentry is enabled in the assist page. Also, check if vmx->nested.enlightened_vmcs_enabled to minimize the impact for 'unenlightened' workloads.

Emulating an L1 INVEPT does require synchronizing the appropriate shadow EPT root(s), but a call to kvm_mmu_sync_roots in this context won't do that. Similarly, the hardware TLB and paging-structure-cache entries associated with the appropriate shadow EPT root(s) must be flushed, but requesting a TLB_FLUSH from this context won't do that either. How did this ever work? KVM always does a sync_roots and TLB flush (in the correct context) when transitioning from L1 to L2. That isn't the best choice for nested VM performance, but it effectively papers over the mistakes here. Remove the unnecessary operations and leave a comment to try to do better in the future.

As indicated by vmx->nested.enlightened_vmcs_enabled. This is quite bizarre as userspace VMM should make sure to expose same vCPU with same CPUID values in both source and destination. In case vCPU is exposed with eVMCS support on CPUID, it is also expected to enable KVM_CAP_HYPERV_ENLIGHTENED_VMCS capability. Therefore, KVM_STATE_NESTED_EVMCS is redundant. KVM_STATE_NESTED_EVMCS is currently used on restore path (vmx_set_nested_state()) only to enable eVMCS capability in KVM and to signal need_vmcs12_sync such that on next VMEntry to guest nested_sync_from_vmcs12() will be called to sync vmcs12 content into eVMCS in guest memory. However, because restore nested-state is rare enough, we could have just modified vmx_set_nested_state() to always signal need_vmcs12_sync. From all the above, it seems that we could have just removed the usage of KVM_STATE_NESTED_EVMCS. However, in order to preserve backwards migration compatibility, we cannot do that. (vmx_get_nested_state() needs to signal flag when migrating from new kernel to old kernel). Returning KVM_STATE_NESTED_EVMCS when just vCPU have eVMCS enabled have a bad side-effect of userspace VMM having to send nested-state from source to destination as part of migration stream. Even if guest have never used eVMCS as it doesn't even run a nested hypervisor workload. This requires destination userspace VMM and KVM to support setting nested-state. Which make it more difficult to migrate from new host to older host. To avoid this, change KVM_STATE_NESTED_EVMCS to signal eVMCS is not only enabled but also active. i.e. Guest have made some eVMCS active via an enlightened VMEntry. i.e. vmcs12 is copied from eVMCS and therefore should be restored into eVMCS resident in memory (by copy_vmcs12_to_enlightened()).

For example, some tests for the wireless subsystem and userspace are based on hwsim, a virtual wireless adapter. Some tests can take a long time to run because they e.g. wait for 120 seconds to elapse for some regulatory checks. This obviously goes faster if it need not actually wait that long, but time inside the test environment just "bumps up" when there's nothing to do. Add CONFIG_UML_TIME_TRAVEL_SUPPORT to enable code to support such modes at runtime, selected on the command line: * just "time-travel", in which time inside the UML instance can move faster than real time, if there's nothing to do * "time-travel=inf-cpu" in which time also moves slower and any CPU processing takes no time at all, which allows to implement consistent behaviour regardless of host CPU load (or speed) or debug overhead. An additional "time-travel-start=" parameter is also supported in this case to start the wall clock at this time (in unix epoch). With this enabled, the test mentioned above goes from a runtime of about 140 seconds (with startup overhead and all) to being CPU bound and finishing in 15 seconds (on my slow laptop).

There are two requirements: perform idle wake up quickly; and save everything including CFAR for non-idle interrupts, with no performance requirement. The problem with placing the idle test in the middle of the handler and using the normal handler code to save CFAR, is that it's quite costly (e.g., mfcfar is serialising, speculative workarounds get applied, SRR1 has to be reloaded, etc). It also prevents the standard interrupt handler boilerplate being used. This pain can be avoided by using a dedicated idle interrupt handler at the start of the interrupt handler, which restores all registers back to the way they were in case it was not an idle wake up. CFAR is preserved without saving it before the non-idle case by making that the fall-through, and idle is a taken branch. Performance seems to be in the noise, but possibly around 0.5% faster, the executed instructions certainly look better. The bigger benefit is being able to drop in standard interrupt handlers after the idle code, which helps with subsequent cleanup and consolidation.

By default there is no change in behavior. This enables SWIOTLB when the "swiotlb" kernel parameter is set to "force".

However if the property is missing or zero sized, then there is no fallback of any kind and the PCI resources remain undiscovered, i.e. pdev->resource[] array remains empty. This adds a fallback which parses the "reg" property in pretty much same way except it marks resources as "unset" which later make Linux assign those resources proper addresses. This has an effect when: 1. a hypervisor failed to assign any resource for a device; 2. /chosen/linux,pci-probe-only=0 is in the DT so the system may try assigning a resource. Neither is likely to happen under PowerVM.

These ops need an iommu_table pointer which is stored in dev->archdata.iommu_table_base. It is initialized during pcibios_setup_device() which handles boot time devices. However when a device is taken from the system in order to pass it through, the default IOMMU table is destroyed but the pointer in a device is not updated; also when a device is returned back to the system, a new table pointer is not stored in dev->archdata.iommu_table_base either. So when a just returned device tries using IOMMU, it crashes on accessing stale iommu_table or its members. This calls set_iommu_table_base() when the default window is created. Note it used to be there before but was wrongly removed (see "fixes"). It did not appear before as these days most devices simply use bypass.

That means the interrupt has been sent to the target CPUs local APIC, but the target CPU is in a state which delays the servicing. So free_irq() would proceed to free resources and to clear the vector because synchronize_hardirq() does not see an interrupt handler in progress. That can trigger a spurious interrupt warning, which is harmless and just confuses users, but it also can leave the remote IRR in a stale state because once the handler is invoked the interrupt resources might be freed already and therefore acknowledgement is not possible anymore. Implement the irq_get_irqchip_state() callback for the IO-APIC irq chip. The callback is invoked from free_irq() via __synchronize_hardirq(). Check the remote IRR bit of the interrupt and return 'in flight' if it is set and the interrupt is configured in level mode. For edge mode the remote IRR has no meaning. As this is only meaningful for level triggered interrupts this won't cure the potential spurious interrupt warning for edge triggered interrupts, but the edge trigger case does not result in stale hardware state. This has to be addressed at the vector/interrupt entry level seperately.

Robert provided some more information and did an initial analysis. The following situation leads to these warnings: CPU 0 CPU 1 IO_APIC interrupt is raised sent to CPU1 Unable to handle immediately (interrupts off, deep idle delay) mask() ... free() shutdown() synchronize_irq() clear_vector() do_IRQ() -> vector is clear Before the rework the vector entries of legacy interrupts were statically assigned and occupied precious vector space while most of them were unused. Due to that the above situation was handled silently because the vector was handled and the core handler of the assigned interrupt descriptor noticed that it is shut down and returned. While this has been usually observed with legacy interrupts, this situation is not limited to them. Any other interrupt source, e.g. MSI, can cause the same issue. After adding proper synchronization for level triggered interrupts, this can only happen for edge triggered interrupts where the IO-APIC obviously cannot provide information about interrupts in flight. While the spurious warning is actually harmless in this case it worries users and driver developers. Handle it gracefully by marking the vector entry as VECTOR_SHUTDOWN instead of VECTOR_UNUSED when the vector is freed up. If that above late handling happens the spurious detector will not complain and switch the entry to VECTOR_UNUSED. Any subsequent spurious interrupt on that line will trigger the spurious warning as before.

Sounds reasonable, but it's subtly broken. The spurious interrupt vector entry point pushes vector number 0xFF on the stack which makes the whole logic in __smp_spurious_interrupt() pointless. As a consequence any spurious interrupt which comes from a vector != 0xFF is treated as a real spurious interrupt (vector 0xFF) and not acknowledged. That subsequently stalls all interrupt vectors of equal and lower priority, which brings the system to a grinding halt. This can happen because even on 64-bit the system vector space is not guaranteed to be fully populated. A full compile time handling of the unused vectors is not possible because quite some of them are conditonally populated at runtime. Bring the entry stubs back, which wastes 160 bytes if all stubs are unused, but gains the proper handling back. There is no point to selectively spare some of the stubs which are known at compile time as the required code in the IDT management would be way larger and convoluted. Do not route the spurious entries through common_interrupt and do_IRQ() as the original code did. Route it to smp_spurious_interrupt() which evaluates the vector number and acts accordingly now that the real vector numbers are handed in. Fixup the pr_warn so the actual spurious vector (0xff) is clearly distiguished from the other vectors and also note for the vectored case whether it was pending in the ISR or not. "Spurious APIC interrupt (vector 0xFF) on CPU#0, should never happen." "Spurious interrupt vector 0xed on CPU#1. Acked." "Spurious interrupt vector 0xee on CPU#1. Not pending!."

Move the existing clocksource code under drivers/hv and arch/x86 to the new clocksource driver while separating out the ISA dependencies. Update Hyper-V initialization to call initialization and cleanup routines since the Hyper-V synthetic clock is not independently enumerated in ACPI. Update Hyper-V clocksource users in KVM and VDSO to get definitions from the new include file. No behavior is changed and no new functionality is added.

The expected behavior is a no-op, whereas the current implementation changes bits in the destination register. The following example demonstrates the bug. The expected result of this program is 1, but the current JITed code returns 2. r0 = 1 r1 = 1 r2 = 0 r1 <<= r2 if r1 == 1 goto end r0 = 2 end: exit The bug is caused by an incorrect assumption by the JIT that a shift by 32 clear the register. On x32 however, shifts use the lower 5 bits of the source, making a shift by 32 equivalent to a shift by 0. This patch fixes the bug using double-precision shifts, which also simplifies the code.

The expected behavior is for this to be a no-op. The following program demonstrates the bug. The expexceted result is 1, but the current JITed code returns 2. r0 = 1 r1 = 1 r1 <<= 0 if r1 == 1 goto end r0 = 2 end: exit This patch simplifies the code and fixes the bug.

implement 5 way interleave for ECB, CBC and CTR This implements 5-way interleaving for ECB, CBC decryption and CTR, resulting in a speedup of ~11% on Marvell ThunderX2, which has a very deep pipeline and therefore a high issue latency for NEON instructions operating on the same registers. Note that XTS is left alone: implementing 5-way interleave there would either involve spilling of the calculated tweaks to the stack, or recalculating them after the encryption operation, and doing either of those would most likely penalize low end cores. For ECB, this is not a concern at all, given that we have plenty of spare registers. For CTR and CBC decryption, we take advantage of the fact that v16 is not used by the CE version of the code (which is the only one targeted by the optimization), and so we can reshuffle the code a bit and avoid having to spill to memory (with the exception of one extra reload in the CBC routine) Signed-off-by: Ard Biesheuvel Signed-off-by: Herbert Xu --- arch/arm64/crypto/aes-ce.S | 2 + arch/arm64/crypto/aes-modes.S | 102 +++++++++++++++++++++++++++++------------- arch/arm64/crypto/aes-neon.S | 2 + 3 files changed, 75 insertions(+), 31 deletions(-) (limited to 'arch') diff --git a/arch/arm64/crypto/aes-ce.S b/arch/arm64/crypto/aes-ce.S index 0fca5f463406..dbfc04ea20c7 100644 --- a/arch/arm64/crypto/aes-ce.S +++ b/arch/arm64/crypto/aes-ce.S @@ -18,6 +18,8 @@ .arch armv8-a+crypto xtsmask .req v16 + cbciv .req v16 + vctr .req v16 .macro xts_reload_mask, tmp .endm diff --git a/arch/arm64/crypto/aes-modes.S b/arch/arm64/crypto/aes-modes.S index add6267f9e3a..3f60f7b152bf 100644 --- a/arch/arm64/crypto/aes-modes.S +++ b/arch/arm64/crypto/aes-modes.S @@ -17,6 +17,14 @@ #define MAX_STRIDE 4 #endif +#if MAX_STRIDE == 4 +#define ST4(x...) x +#define ST5(x...) +#else +#define ST4(x...) +#define ST5(x...) x +#endif + aes_encrypt_block4x: encrypt_block4x v0, v1, v2, v3, w3, x2, x8, w7 ret @@ -53,14 +61,17 @@ AES_ENTRY(aes_ecb_encrypt) enc_prepare w3, x2, x5 .LecbencloopNx: - subs w4, w4, #4 + subs w4, w4, #MAX_STRIDE bmi .Lecbenc1x ld1 {v0.16b-v3.16b}, [x1], #64 /* get 4 pt blocks */ - bl aes_encrypt_block4x +ST4( bl aes_encrypt_block4x ) +ST5( ld1 {v4.16b}, [x1], #16 ) +ST5( bl aes_encrypt_block5x ) st1 {v0.16b-v3.16b}, [x0], #64 +ST5( st1 {v4.16b}, [x0], #16 ) b .LecbencloopNx .Lecbenc1x: - adds w4, w4, #4 + adds w4, w4, #MAX_STRIDE beq .Lecbencout .Lecbencloop: ld1 {v0.16b}, [x1], #16 /* get next pt block */ @@ -81,14 +92,17 @@ AES_ENTRY(aes_ecb_decrypt) dec_prepare w3, x2, x5 .LecbdecloopNx: - subs w4, w4, #4 + subs w4, w4, #MAX_STRIDE bmi .Lecbdec1x ld1 {v0.16b-v3.16b}, [x1], #64 /* get 4 ct blocks */ - bl aes_decrypt_block4x +ST4( bl aes_decrypt_block4x ) +ST5( ld1 {v4.16b}, [x1], #16 ) +ST5( bl aes_decrypt_block5x ) st1 {v0.16b-v3.16b}, [x0], #64 +ST5( st1 {v4.16b}, [x0], #16 ) b .LecbdecloopNx .Lecbdec1x: - adds w4, w4, #4 + adds w4, w4, #MAX_STRIDE beq .Lecbdecout .Lecbdecloop: ld1 {v0.16b}, [x1], #16 /* get next ct block */ @@ -148,39 +162,56 @@ AES_ENTRY(aes_cbc_decrypt) stp x29, x30, [sp, #-16]! mov x29, sp - ld1 {v7.16b}, [x5] /* get iv */ + ld1 {cbciv.16b}, [x5] /* get iv */ dec_prepare w3, x2, x6 .LcbcdecloopNx: - subs w4, w4, #4 + subs w4, w4, #MAX_STRIDE bmi .Lcbcdec1x ld1 {v0.16b-v3.16b}, [x1], #64 /* get 4 ct blocks */ +#if MAX_STRIDE == 5 + ld1 {v4.16b}, [x1], #16 /* get 1 ct block */ + mov v5.16b, v0.16b + mov v6.16b, v1.16b + mov v7.16b, v2.16b + bl aes_decrypt_block5x + sub x1, x1, #32 + eor v0.16b, v0.16b, cbciv.16b + eor v1.16b, v1.16b, v5.16b + ld1 {v5.16b}, [x1], #16 /* reload 1 ct block */ + ld1 {cbciv.16b}, [x1], #16 /* reload 1 ct block */ + eor v2.16b, v2.16b, v6.16b + eor v3.16b, v3.16b, v7.16b + eor v4.16b, v4.16b, v5.16b +#else mov v4.16b, v0.16b mov v5.16b, v1.16b mov v6.16b, v2.16b bl aes_decrypt_block4x sub x1, x1, #16 - eor v0.16b, v0.16b, v7.16b + eor v0.16b, v0.16b, cbciv.16b eor v1.16b, v1.16b, v4.16b - ld1 {v7.16b}, [x1], #16 /* reload 1 ct block */ + ld1 {cbciv.16b}, [x1], #16 /* reload 1 ct block */ eor v2.16b, v2.16b, v5.16b eor v3.16b, v3.16b, v6.16b +#endif st1 {v0.16b-v3.16b}, [x0], #64 +ST5( st1 {v4.16b}, [x0], #16 ) b .LcbcdecloopNx .Lcbcdec1x: - adds w4, w4, #4 + adds w4, w4, #MAX_STRIDE beq .Lcbcdecout .Lcbcdecloop: ld1 {v1.16b}, [x1], #16 /* get next ct block */ mov v0.16b, v1.16b /* ...and copy to v0 */ decrypt_block v0, w3, x2, x6, w7 - eor v0.16b, v0.16b, v7.16b /* xor with iv => pt */ - mov v7.16b, v1.16b /* ct is next iv */ + eor v0.16b, v0.16b, cbciv.16b /* xor with iv => pt */ + mov cbciv.16b, v1.16b /* ct is next iv */ st1 {v0.16b}, [x0], #16 subs w4, w4, #1 bne .Lcbcdecloop .Lcbcdecout: - st1 {v7.16b}, [x5] /* return iv */ + st1 {cbciv.16b}, [x5] /* return iv */ ldp x29, x30, [sp], #16 ret AES_ENDPROC(aes_cbc_decrypt) @@ -274,51 +305,60 @@ AES_ENTRY(aes_ctr_encrypt) mov x29, sp enc_prepare w3, x2, x6 - ld1 {v4.16b}, [x5] + ld1 {vctr.16b}, [x5] - umov x6, v4.d[1] /* keep swabbed ctr in reg */ + umov x6, vctr.d[1] /* keep swabbed ctr in reg */ rev x6, x6 cmn w6, w4 /* 32 bit overflow?

SPDX-License-Identifier: GPL-2.0 - -Using FS and GS segments in user space applications -=================================================== - -The x86 architecture supports segmentation. Instructions which access -memory can use segment register based addressing mode. The following -notation is used to address a byte within a segment: - - Segment-register:Byte-address - -The segment base address is added to the Byte-address to compute the -resulting virtual address which is accessed. This allows to access multiple -instances of data with the identical Byte-address, i.e. the same code. The -selection of a particular instance is purely based on the base-address in -the segment register. - -In 32-bit mode the CPU provides 6 segments, which also support segment -limits. The limits can be used to enforce address space protections. - -In 64-bit mode the CS/SS/DS/ES segments are ignored and the base address is -always 0 to provide a full 64bit address space. The FS and GS segments are -still functional in 64-bit mode. - -Common FS and GS usage ------------------------------- - -The FS segment is commonly used to address Thread Local Storage (TLS). FS -is usually managed by runtime code or a threading library. Variables -declared with the '__thread' storage class specifier are instantiated per -thread and the compiler emits the FS: address prefix for accesses to these -variables. Each thread has its own FS base address so common code can be -used without complex address offset calculations to access the per thread -instances. Applications should not use FS for other purposes when they use -runtimes or threading libraries which manage the per thread FS. - -The GS segment has no common use and can be used freely by -applications. GCC and Clang support GS based addressing via address space -identifiers. - -Reading and writing the FS/GS base address ------------------------------------------- - -There exist two mechanisms to read and write the FS/FS base address: - - - the arch_prctl() system call - - - the FSGSBASE instruction family - -Accessing FS/GS base with arch_prctl() --------------------------------------- - - The arch_prctl(2) based mechanism is available on all 64bit CPUs and all - kernel versions. - - Reading the base: - - arch_prctl(ARCH_GET_FS, &fsbase); - arch_prctl(ARCH_GET_GS, &gsbase); - - Writing the base: - - arch_prctl(ARCH_SET_FS, fsbase); - arch_prctl(ARCH_SET_GS, gsbase); - - The ARCH_SET_GS prctl may be disabled depending on kernel configuration - and security settings. - -Accessing FS/GS base with the FSGSBASE instructions ---------------------------------------------------- - - With the Ivy Bridge CPU generation Intel introduced a new set of - instructions to access the FS and GS base registers directly from user - space. These instructions are also supported on AMD Family 17H CPUs. The - following instructions are available: - - =============== =========================== - RDFSBASE %reg Read the FS base register - RDGSBASE %reg Read the GS base register - WRFSBASE %reg Write the FS base register - WRGSBASE %reg Write the GS base register - =============== =========================== - - The instructions avoid the overhead of the arch_prctl() syscall and allow - more flexible usage of the FS/GS addressing modes in user space - applications. This does not prevent conflicts between threading libraries - and runtimes which utilize FS and applications which want to use it for - their own purpose. - -FSGSBASE instructions enablement -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - The instructions are enumerated in CPUID leaf 7, bit 0 of EBX. If - available /proc/cpuinfo shows 'fsgsbase' in the flag entry of the CPUs. - - The availability of the instructions does not enable them - automatically. The kernel has to enable them explicitly in CR4. The - reason for this is that older kernels make assumptions about the values in - the GS register and enforce them when GS base is set via - arch_prctl(). Allowing user space to write arbitrary values to GS base - would violate these assumptions and cause malfunction. - - On kernels which do not enable FSGSBASE the execution of the FSGSBASE - instructions will fault with a #UD exception. - - The kernel provides reliable information about the enabled state in the - ELF AUX vector. If the HWCAP2_FSGSBASE bit is set in the AUX vector, the - kernel has FSGSBASE instructions enabled and applications can use them. - The following code example shows how this detection works:: - - #include - #include - - /* Will be eventually in asm/hwcap.h */ - #ifndef HWCAP2_FSGSBASE - #define HWCAP2_FSGSBASE (1 << 1) - #endif - - .... - - unsigned val = getauxval(AT_HWCAP2); - - if (val & HWCAP2_FSGSBASE) - printf("FSGSBASE enabled\n"); - -FSGSBASE instructions compiler support -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -GCC version 4.6.4 and newer provide instrinsics for the FSGSBASE -instructions. Clang supports them as well. - - =================== =========================== - _readfsbase_u64() Read the FS base register - _readfsbase_u64() Read the GS base register - _writefsbase_u64() Write the FS base register - _writegsbase_u64() Write the GS base register - =================== =========================== - -To utilize these instrinsics must be included in the source -code and the compiler option -mfsgsbase has to be added. - -Compiler support for FS/GS based addressing -------------------------------------------- - -GCC version 6 and newer provide support for FS/GS based addressing via -Named Address Spaces. GCC implements the following address space -identifiers for x86: - - ========= ==================================== - __seg_fs Variable is addressed relative to FS - __seg_gs Variable is addressed relative to GS - ========= ==================================== - -The preprocessor symbols __SEG_FS and __SEG_GS are defined when these -address spaces are supported. Code which implements fallback modes should -check whether these symbols are defined. Usage example:: - - #ifdef __SEG_GS - - long data0 = 0; - long data1 = 1; - - long __seg_gs *ptr; - - /* Check whether FSGSBASE is enabled by the kernel (HWCAP2_FSGSBASE) */ - .... - - /* Set GS to point to data0 */ - _writegsbase_u64(&data0); - - /* Access offset 0 of GS */ - ptr = 0; - printf("data0 = %ld\n", *ptr); - - /* Set GS to point to data1 */ - _writegsbase_u64(&data1); - /* ptr still addresses offset 0! */ - printf("data1 = %ld\n", *ptr); - - -Clang does not provide the GCC address space identifiers, but it provides -address spaces via an attribute based mechanism in Clang 5 and newer -versions: - - ==================================== ===================================== - __attribute__((address_space(256)) Variable is addressed relative to GS - __attribute__((address_space(257)) Variable is addressed relative to FS - ==================================== ===================================== - -FS/GS based addressing with inline assembly -------------------------------------------- - -In case the compiler does not support address spaces, inline assembly can -be used for FS/GS based addressing mode:: - - mov %fs:offset, %reg - mov %gs:offset, %reg - - mov %reg, %fs:offset - mov %reg, %gs:offset diff --git a/Documentation/x86/x86_64/index.rst b/Documentation/x86/x86_64/index.rst index a56070fc8e77..d6eaaa5a35fc 100644 --- a/Documentation/x86/x86_64/index.rst +++ b/Documentation/x86/x86_64/index.rst @@ -14,4 +14,3 @@ x86_64 Support fake-numa-for-cpusets cpu-hotplug-spec machinecheck - fsgs diff --git a/arch/x86/entry/calling.h b/arch/x86/entry/calling.h index d3fbe2dc03ea..efb0d1b1f15f 100644 --- a/arch/x86/entry/calling.h +++ b/arch/x86/entry/calling.h @@ -6,7 +6,6 @@ #include #include #include -#include /* @@ -338,12 +337,6 @@ For 32-bit we have the following conventions - kernel is built with #endif .endm -.macro SAVE_AND_SET_GSBASE scratch_reg:req save_reg:req - rdgsbase \save_reg - GET_PERCPU_BASE \scratch_reg - wrgsbase \scratch_reg -.endm - #endif /* CONFIG_X86_64 */ .macro STACKLEAK_ERASE @@ -352,39 +345,6 @@ For 32-bit we have the following conventions - kernel is built with #endif .endm -#ifdef CONFIG_SMP - -/* - * CPU/node NR is loaded from the limit (size) field of a special segment - * descriptor entry in GDT. - */ -.macro LOAD_CPU_AND_NODE_SEG_LIMIT reg:req - movq $__CPUNODE_SEG, \reg - lsl \reg, \reg -.endm - -/* - * Fetch the per-CPU GSBASE value for this processor and put it in @reg. - * We normally use %gs for accessing per-CPU data, but we are setting up - * %gs here and obviously can not use %gs itself to access per-CPU data. - */ -.macro GET_PERCPU_BASE reg:req - ALTERNATIVE \ - "LOAD_CPU_AND_NODE_SEG_LIMIT \reg", \ - "RDPID \reg", \ - X86_FEATURE_RDPID - andq $VDSO_CPUNODE_MASK, \reg - movq __per_cpu_offset(, \reg, 8), \reg -.endm - -#else - -.macro GET_PERCPU_BASE reg:req - movq pcpu_unit_offsets(%rip), \reg -.endm - -#endif /* CONFIG_SMP */ - /* * This does 'call enter_from_user_mode' unless we can avoid it based on * kernel config or using the static jump infrastructure. diff --git a/arch/x86/entry/entry_64.S b/arch/x86/entry/entry_64.S index 670306f588bf..3b7a0e8d3bc0 100644 --- a/arch/x86/entry/entry_64.S +++ b/arch/x86/entry/entry_64.S @@ -38,7 +38,6 @@ #include #include #include -#include #include #include "calling.h" @@ -948,6 +947,7 @@ ENTRY(\sym) addq $\ist_offset, CPU_TSS_IST(\shift_ist) .endif + /* these procedures expect "no swapgs" flag in ebx */ .if \paranoid jmp paranoid_exit .else @@ -1164,21 +1164,24 @@ idtentry machine_check do_mce has_error_code=0 paranoid=1 #endif /* - * Save all registers in pt_regs.

Rao" Date: Wed, 3 Jul 2019 22:33:57 +0530 Subject: powerpc/pseries: Introduce rwlock to gatekeep DTLB usage Since we would be introducing a new user of the DTL buffer in a subsequent patch, we need a way to gatekeep use of the DTL buffer. The current debugfs interface for DTL allows registering and opening cpu-specific DTL buffers. Cpu specific files are exposed under debugfs 'powerpc/dtl/' node, and changing 'dtl_event_mask' in the same directory enables controlling the event mask used when registering DTL buffer for a particular cpu. Subsequently, we will be introducing a user of the DTL buffers that registers access to the DTL buffers across all cpus with the same event mask. To ensure these two users do not step on each other, we introduce a rwlock to gatekeep DTL buffer access. This fits the requirement of the current debugfs interface wanting to allow multiple independent cpu-specific users (read lock), and the subsequent user wanting exclusive access (write lock).

Rao" Date: Wed, 3 Jul 2019 22:34:00 +0530 Subject: powerpc/pseries: Provide vcpu dispatch statistics For Shared Processor LPARs, the POWER Hypervisor maintains a relatively static mapping of the LPAR processors (vcpus) to physical processor chips (representing the "home" node) and tries to always dispatch vcpus on their associated physical processor chip. However, under certain scenarios, vcpus may be dispatched on a different processor chip (away from its home node). The actual physical processor number on which a certain vcpu is dispatched is available to the guest in the 'processor_id' field of each DTL entry. The guest can discover the home node of each vcpu through the H_HOME_NODE_ASSOCIATIVITY(flags=1) hcall. The guest can also discover the associativity of physical processors, as represented in the DTL entry, through the H_HOME_NODE_ASSOCIATIVITY(flags=2) hcall. These can then be compared to determine if the vcpu was dispatched on its home node or not. If the vcpu was not dispatched on the home node, it is possible to determine if the vcpu was dispatched in a different chip, socket or drawer. Introduce a procfs file /proc/powerpc/vcpudispatch_stats that can be used to obtain these statistics. Writing '1' to this file enables collecting the statistics, while writing '0' disables the statistics. The statistics themselves are available by reading the procfs file. By default, the DTLB log for each vcpu is processed 50 times a second so as not to miss any entries. This processing frequency can be changed through /proc/powerpc/vcpudispatch_stats_freq.

We want to make sure we look at the uuid read from device tree in an endian-neutral fashion. For now, I am picking little-endian to be format so that we don't end up doing an additional conversion. The reason to store in a specific endian format is to enable reading the namespace created with a little-endian kernel config on a big-endian kernel. We do store the device tree uuid string as a 64-bit little-endian cookie in the label area. When booting the kernel we also compare this cookie against what is read from the device tree. For this, to work we have to store and compare these values in a CPU endian config independent fashion.

Some SCC functions like the QMC requires an extended parameter RAM. On modern 8xx (ie 866 and 885), SPI area can already be relocated, allowing the use of those functions on SCC2. But SCC3 and SCC4 parameter RAM collide with SMC1 and SMC2 parameter RAMs. This patch adds microcode to allow the relocation of both SMC1 and SMC2, and relocate them at offsets 0x1ec0 and 0x1fc0. Those offsets are by default for the CPM1 DSP1 and DSP2, but there is no kernel driver using them at the moment so this area can be reused.

This was causing sparse and clang to complain, while GCC compiled cleanly. Commit 0c529ff789bc addressed this problem, but since vq_present() is no longer a function, there is now no implicit casting of the returned value to the return type (bool). In set_sve_vls(), this uncast bit value is compared against a bool, and so may spuriously compare as unequal when both are nonzero. As a result, KVM may reject valid SVE vector length configurations as invalid, and vice versa. Fix it by forcing the returned value to a bool.

So move the pure prototype kdocs of ("s390: include/asm/debug.h add kerneldoc markups") from debug.h to debug.c and merge them with the old function docs. Also, I had the impression that kdoc typically is at the implementation in the compile unit rather than at the prototype in the header file. While at it, update the short kdoc description to distinguish the different functions. And a few more consistency cleanups. Added a new kdoc for debug_set_critical() since debug.h comments it as part of the API.

In such a case, KVM must restore L1's state to the pre-VM-Enter state as L2's state has already been loaded into KVM's software model. L1's CR3 and PDPTRs in particular are loaded from vmcs01.GUEST_*. But when EPT is disabled, the associated fields hold KVM's shadow values, not L1's "real" values. Fortunately, when EPT is disabled the PDPTRs come from memory, i.e. are not cached in the VMCS. Which leaves CR3 as the sole anomaly. A previously applied workaround to handle CR3 was to force nested early checks if EPT is disabled: commit 2b27924bb1d48 ("KVM: nVMX: always use early vmcs check when EPT is disabled") Forcing nested early checks is undesirable as doing so adds hundreds of cycles to every nested VM-Entry. Rather than take this performance hit, handle CR3 by overwriting vmcs01.GUEST_CR3 with L1's CR3 during nested VM-Entry when EPT is disabled *and* nested early checks are disabled. By stuffing vmcs01.GUEST_CR3, nested_vmx_restore_host_state() will naturally restore the correct vcpu->arch.cr3 from vmcs01.GUEST_CR3. These shenanigans work because nested_vmx_restore_host_state() does a full kvm_mmu_reset_context(), i.e. unloads the current MMU, which guarantees vmcs01.GUEST_CR3 will be rewritten with a new shadow CR3 prior to re-entering L1. vcpu->arch.root_mmu.root_hpa is set to INVALID_PAGE via: nested_vmx_restore_host_state() -> kvm_mmu_reset_context() -> kvm_mmu_unload() -> kvm_mmu_free_roots() kvm_mmu_unload() has WARN_ON(root_hpa != INVALID_PAGE), i.e. we can bank on 'root_hpa == INVALID_PAGE' unless the implementation of kvm_mmu_reset_context() is changed. On the way into L1, VMCS.GUEST_CR3 is guaranteed to be written (on a successful entry) via: vcpu_enter_guest() -> kvm_mmu_reload() -> kvm_mmu_load() -> kvm_mmu_load_cr3() -> vmx_set_cr3() Stuff vmcs01.GUEST_CR3 if and only if nested early checks are disabled as a "late" VM-Fail should never happen win that case (KVM WARNs), and the conditional write avoids the need to restore the correct GUEST_CR3 when nested_vmx_check_vmentry_hw() fails.

This lets us use it in places like the vectors without having to use alternatives. If someone disables CONFIG_ARM64_RAS_EXTN, this instruction still has its RAS extensions behaviour, but we no longer read DISR_EL1 as this register does depend on alternatives. This could go wrong if we want to synchronize an SError from a KVM guest. On a CPU that has the RAS extensions, but the KConfig option was disabled, we consume the pending SError with no chance of ever reading it. Hide the ESB-instruction behind the CONFIG_ARM64_RAS_EXTN option, outputting a regular nop if the feature has been disabled.

The generated sequences already do some of the early guest-exit work (i.e. saving registers). To avoid duplication the generated vectors branch to the original vector just after the preamble. This size is hard coded. Adding new instructions to the HYP vector causes strange side effects, which are difficult to debug as the affected code is patched in at runtime. Add KVM_VECTOR_PREAMBLE to tell kvm_patch_vector_branch() how big the preamble is. The valid_vect macro can then validate this at build time.

Patching the head or tail of the vector shouldn't remove preamble instructions. Today, this is easy as we only have one instruction in the preamble. Change the unpatched tail of the indirect vector so that it always runs this, regardless of patching.

This saves the unmasking and remasking of asynchronous exceptions. We do this after we've saved the guest registers and restored the host's. Any SError that becomes pending due to this will be accounted to the guest, when it actually occurred during host-execution. Move the ESB-instruction as early as possible. Any guest SError will become pending due to this ESB-instruction and then consumed to DISR_EL1 before the host touches anything. This lets us account for host/guest SError precisely on the guest exit exception boundary. Because the ESB-instruction now lands in the preamble section of the vectors, we need to add it to the unpatched indirect vectors too, and to any sequence that may be patched in over the top. The ESB-instruction always lives in the head of the vectors, to be before any memory write. Whereas the register-store always lives in the tail.

Reading DISR_EL1 before guest entry requires free registers, and using ESB+DISR_EL1 to consume and read back the ESR would leave KVM holding a host SError... We would rather leave the SError pending and let the host take it once we exit world-switch. To do this, we need to defer guest-entry if an SError is pending. Read the ISR to see if SError (or an IRQ) is pending. If so fake an exit. Place this check between __guest_enter()'s save of the host registers, and restore of the guest's. SError that occur between here and the eret into the guest must have affected the guest's registers, which we can naturally attribute to the guest. The dsb is needed to ensure any previous writes have been done before we read ISR_EL1. On systems without the v8.2 RAS extensions this doesn't give us anything as we can't contain errors, and the ESR bits to describe the severity are all implementation-defined. Replace this with a nop for these systems.

Now that KVM attributes SError to the host/guest more precisely the host's architecture code will always handle host errors that become pending during world-switch. Errors misclassified by this errata that affected the guest will be re-injected to the guest as an implementation-defined SError, which can be uncontained.

Guests may use this interface to ensure mitigation is active. If we want to migrate such a guest to a host with a different support level for those workarounds, migration might need to fail, to ensure that critical guests don't loose their protection. Introduce a way for userland to save and restore the workarounds state. On restoring we do checks that make sure we don't downgrade our mitigation level.

As a result, it is necessary to add duplicate definitions for any system register that already needs a definition in sysreg.h for other reasons. This is a bit of a maintenance headache, and the reasons for the _el*() accessors working the way they do is a bit historical. This patch gets rid of the shadow sysreg definitions in , converts the _el*() accessors to use the core __msr_s/__mrs_s interface, and converts all call sites to use the standard sysreg #define names (i.e., upper case, with SYS_ prefix). This patch will conflict heavily anyway, so the opportunity to clean up some bad whitespace in the context of the changes is taken. The change exposes a few system registers that have no sysreg.h definition, due to msr_s/mrs_s being used in place of msr/mrs: additions are made in order to fill in the gaps.

This only 'works' with CONFIG_MATH_EMULATION enabled. But on 64bit this cannot work because user space expects SSE to work which required basic FPU support. MATH_EMULATION does not help because SSE is not emulated. The command line option `nofxsr' should also be limited to 32bit because FXSR is part of the required flags on 64bit so turning it off is not possible. Clearing X86_FEATURE_FPU without emulation enabled will not work anyway and hang in fpu__init_system_early_generic() before the console is enabled. Setting additioal dependencies, ensures that the CPU still boots on a modern CPU. Otherwise, dropping FPU will leave FXSR enabled causing the kernel to crash early in fpu__init_system_mxcsr(). With XSAVE support it will crash in fpu__init_cpu_xstate(). The problem is that xsetbv() with XMM set and SSE cleared is not allowed. That means XSAVE has to be disabled. The XSAVE support is disabled in fpu__init_system_xstate_size_legacy() but it is too late. It can be removed, it has been added in commit 1f999ab5a1360 ("x86, xsave: Disable xsave in i387 emulation mode") to use `no387' on a CPU with XSAVE support. All this happens before console output. After hat, the next possible crash is in RAID6 detect code because MMX remained enabled. With a 3DNOW enabled config it will explode in memcpy() for instance due to kernel_fpu_begin() but this is unconditionally enabled. This is enough to boot a Debian Wheezy on a 32bit qemu "host" CPU which supports everything up to XSAVES, AVX2 without 3DNOW. Later, Debian increased the minimum requirements to i686 which means it does not boot userland atleast due to CMOV. After masking the additional features it still keeps SSE4A and 3DNOW* enabled (if present on the host) but those are unused in the kernel. Restrict `no387' and `nofxsr' otions to 32bit only.

Apparently this can be greatly simplified by returning from pure kernel mode (iso interrupt) so drop to pure kernel mdoe and execute the normal exception return path. Testing this was a bit of challenge as return from interrupt is rarely executed now after commit 4de0e52867d83105767 ("ARCv2: STAR 9000814690: Really Re-enable interrupts to avoid deadlocks"). That fix is necessary evil and pct interrupts etc do exercise intr return path. Anyhow after a revert of above in my local test setup I was able to hit this case and verify the patch works.

For now we add 5 Virtio slots in .dts and enable block and network devices via Virtio-MMIO. Note even though typically Virtio register set fits in 0x200 bytes we "allocate" here 0x2000 so that it matches ARC's default 8KiB page size and so remapping of that area is done clearly. We also enable DEVTMPFS automount for more convenient use of external root file-stystem. Before that we used to use built-in Initramfs which didn't automount DEVTMPFS anyways so we didn't need that option, while now it starts making sense.

It turns out that contrary to arm64, cpu_logical_map() on 32bit ARM doesn't return the *full* MPIDR, but a truncated version. This leaves the host MPIDR slightly corrupted after the first run of a VM, since we won't correctly restore the MPIDR on exit. Oops. Since we cannot trust cpu_logical_map(), let's adopt a different strategy. We move the initialization of the host CPU context as part of the per-CPU initialization (which, in retrospect, makes a lot of sense), and directly read the MPIDR from the HW. This is guaranteed to work on both arm and arm64.

Provide XTENSA_SPILL_STACK_RESERVE macro that specifies required stack frame size when register spilling is involved. Replace all uses of 'entry' and 'retw' with the above macros. This makes most of the xtensa assembly code ready for XEA3 and call0 ABI.

Defconfig enables PCIe host and a number of virtio devices. DTS routes legacy PCI IRQs to the first four level-triggered external IRQ lines. CPU core with edge-triggered IRQs among the first four may need a custom DTS to work correctly.

Due to this, the setup_vm() has to map all possible kernel virtual addresses since it does not know size and location of RAM. This means we have kernel mappings for non-existent RAM and any buggy driver (or kernel) code doing out-of-bound access to RAM will not fault and cause underterministic behaviour. Further, the setup_vm() creates PMD mappings (i.e. 2M mappings) for RV64 systems. This means for PAGE_OFFSET=0xffffffe000000000 (i.e. MAXPHYSMEM_128GB=y), the setup_vm() will require 129 pages (i.e. 516 KB) of memory for initial page tables which is never freed. The memory required for initial page tables will further increase if we chose a lower value of PAGE_OFFSET (e.g. 0xffffff0000000000) This patch implements two-staged initial page table setup, as follows: 1. Early (i.e. setup_vm()): This stage maps kernel image and DTB in a early page table (i.e. early_pg_dir). The early_pg_dir will be used only by boot HART so it can be freed as-part of init memory free-up. 2. Final (i.e. setup_vm_final()): This stage maps all possible RAM banks in the final page table (i.e. swapper_pg_dir). The boot HART will start using swapper_pg_dir at the end of setup_vm_final(). All non-boot HARTs directly use the swapper_pg_dir created by boot HART. We have following advantages with this new approach: 1. Kernel mappings for non-existent RAM don't exists anymore. 2. Memory consumed by initial page tables is now indpendent of the chosen PAGE_OFFSET. 3. Memory consumed by initial page tables on RV64 system is 2 pages (i.e. 8 KB) which has significantly reduced and these pages will be freed as-part of the init memory free-up. The patch also provides a foundation for implementing strict kernel mappings where we protect kernel text and rodata using PTE permissions.

The problem is that the KASAN-ified version of int3_magic() is much less trivial than the C code appears. It clobbers several unexpected registers. So when the selftest's INT3 is converted to an emulated call to int3_magic(), the registers are clobbered and Bad Things happen when the function returns. Fix this by converting int3_magic() to the trivial ASM function it should be, avoiding all calling convention issues. Also add ASM_CALL_CONSTRAINT to the INT3 ASM, since it contains a 'CALL'.

I figured out the root cause in lib/decompress_unxz.c: | #ifdef CONFIG_PPC | # define XZ_DEC_POWERPC | #endif CONFIG_PPC is undefined here in the ppc bootwrapper because autoconf.h is not included except by arch/powerpc/boot/serial.c XZ_DEC_POWERPC is not defined, therefore, bcj_powerpc() is not compiled for the bootwrapper. With the next commit passing CONFIG_PPC correctly, we would realize that {get,put}_unaligned_be32 was missing. Unlike the other decompressors, the ppc bootwrapper duplicates all the necessary helpers in arch/powerpc/boot/. The other architectures define __KERNEL__ and pull in helpers for building the decompressors. If ppc bootwrapper had defined __KERNEL__, lib/xz/xz_private.h would have included : | #ifdef __KERNEL__ | # include | # include | # include However, doing so would cause tons of definition conflicts since the bootwrapper has duplicated everything. I just added copies of {get,put}_unaligned_be32, following the bootwrapper coding convention.

The correct dependency is: $(obj)/serial.o: $(obj)/autoconf.h However, I do not see the reason why we need to copy autoconf.h to arch/power/boot/. Nor do I see consistency in the way of passing CONFIG options. decompress.c references CONFIG_KERNEL_GZIP and CONFIG_KERNEL_XZ, which are passed via the command line. serial.c includes autoconf.h to reference a couple of CONFIG options, but this is fragile because we often forget to include "autoconf.h" from source files. In fact, it is already broken. ppc_asm.h references CONFIG_PPC_8xx, but utils.S is not given any way to access CONFIG options. So, CONFIG_PPC_8xx is never defined here. Pass $(LINUXINCLUDE) to make sure CONFIG options are accessible from all .c and .S files in arch/powerpc/boot/. I also removed the -traditional flag to make include/linux/kconfig.h work. This flag makes the preprocessor imitate the behavior of the pre-standard C compiler, but I do not understand why it is necessary.

The reason is that the static key which controls the pinning is marked RO after init. The kvm_intel module contains a CR4 write which requires to update the static key entry list. That obviously does not work when the key is in a RO section. With CONFIG_PARAVIRT enabled this does not happen because the CR4 write uses the paravirt indirection and the actual write function is built in. As the key is intended to be immutable after init, move native_write_cr0/4() out of line. While at it consolidate the update of the cr4 shadow variable and store the value right away when the pinning is initialized on a booting CPU. No point in reading it back 20 instructions later. This allows to confine the static key and the pinning variable to cpu/common and allows to mark them static.

As a result, a tick that fires in the window between VM-Exit and guest_exit_irqoff() will be accounted as system time. While said window is relatively small, it's large enough to be problematic in some configurations, e.g. if VM-Exits are consistently occurring a hair earlier than the tick irq. Intentionally toggle irqs back off so that guest_exit_irqoff() can be used in lieu of guest_exit() in order to avoid the save/restore of flags in guest_exit(). On my Haswell system, "nop; cli; sti" is ~6 cycles, versus ~28 cycles for "pushf; pop ; cli; push ; popf".

Unfortunately this broke EEH MMIO error checking. Detection works by inserting a hook which checks the results of the ioreadXX() set of functions. When a read returns a 0xFFs response we need to check for an error which we do by mapping the (virtual) MMIO address back to a physical address, then mapping physical address to a PCI device via an interval tree. When translating virt -> phys we currently assume the ioremap space is only populated by PAGE_SIZE mappings. If a hugepage mapping is found we emit a WARN_ON(), but otherwise handles the check as though a normal page was found. In pathalogical cases such as copying a buffer containing a lot of 0xFFs from BAR memory this can result in the system not booting because it's too busy printing WARN_ON()s. There's no real reason to assume huge pages can't be present and we're prefectly capable of handling them, so do that.

Provide the necessarry interface for such a task by implementing a new ioctl BIODASDRAS. The ioctl uses the format_data_t data structure for data input: typedef struct format_data_t { unsigned int start_unit; /* from track */ unsigned int stop_unit; /* to track */ unsigned int blksize; /* sectorsize */ unsigned int intensity; } format_data_t; If the intensity is set to 0x40, start_unit and stop_unit are ignored and space for the entire volume is released. Otherwise, if intensity is set to 0, the respective range is released (if possible).

Currently, the last stage boot loaders such as U-Boot can accept only uImage which is an unnecessary additional step in automating boot process. Add an image header that boot loader understands and boot Linux from flat Image directly. This header is based on ARM64 boot image header and provides an opportunity to combine both ARM64 & RISC-V image headers in future. Also make sure that PE/COFF header can co-exist in the same image so that EFI stub can be supported for RISC-V in future. EFI specification needs PE/COFF image header in the beginning of the kernel image in order to load it as an EFI application. In order to support EFI stub, code0 should be replaced with "MZ" magic string and res4(at offset 0x3c) should point to the rest of the PE/COFF header (which will be added during EFI support).

This change includes the required change for x86 as reference and changes the kernel API doc to point to bitops-instrumented.h instead. Rationale: the functions in x86's bitops.h are no longer the kernel API functions, but instead the arch_ prefixed functions, which are then instrumented via bitops-instrumented.h. Other architectures can similarly add support for asm implementations of bitops. The documentation text was derived from x86 and existing bitops asm-generic versions: 1) references to x86 have been removed; 2) as a result, some of the text had to be reworded for clarity and consistency. Tested using lib/test_kasan with bitops tests (pre-requisite patch).

For several architectures the ARCH_SELECT_MEMORY_MODEL has no real effect because the dependencies for the memory model are always evaluated to a single value. Remove the ARCH_SELECT_MEMORY_MODEL from the Kconfigs for these architectures. This patch (of 3): The ARCH_SELECT_MEMORY_MODEL in arch/arm/Kconfig is enabled only when ARCH_SPARSEMEM_ENABLE=y. But in this case, ARCH_SPARSEMEM_DEFAULT is also enabled and this in turn enables SPARSEMEM_MANUAL. Since there is no definition of ARCH_FLATMEM_ENABLE in arch/arm/Kconfig, SPARSEMEM_MANUAL is the only enabled memory model, hence the final selection will evaluate to SPARSEMEM=y. Since ARCH_SPARSEMEM_ENABLE is set to 'y' only by several sub-arch configurations, the default for must sub-arches would be the falback to FLATMEM regardless of ARCH_SELECT_MEMORY_MODEL.

Note that this defines ARCH_HAS_PTE_SPECIAL for mips as mips has pte_special and pte_mkspecial implemented and used in the existing gup code. They are no-op stubs, though which makes me a little unsure if this is really right thing to do. Note that this also adds back a missing cpu_has_dc_aliases check for __get_user_pages_fast, which the old code was only doing for get_user_pages_fast. This clearly looks like an oversight, as any condition that makes get_user_pages_fast unsafe also applies to __get_user_pages_fast.

Add a generic implementation that can be reused across architectures and enable its use on x86. The generic implementation uses GFP_KERNEL | __GFP_ZERO for the kernel page tables and GFP_KERNEL | __GFP_ZERO | __GFP_ACCOUNT for the user page tables. The "base" functions for PTE allocation, namely __pte_alloc_one_kernel() and __pte_alloc_one() are intended for the architectures that require additional actions after actual memory allocation or must use non-default GFP flags. x86 is switched to use generic pte_alloc_one_kernel(), pte_free_kernel() and pte_free(). x86 still implements pte_alloc_one() to allow run-time control of GFP flags required for "userpte" command line option.

The KVM memory cache is now using GFP_PGTABLE_USER. The mappings created with create_pgd_mapping() are now using GFP_PGTABLE_KERNEL. The conversion to the generic version of pte_free_kernel() removes the NULL check for pte. The pte_free() version on arm64 is identical to the generic one and can be simply dropped.

Those bitfields overlap with high order event select bits in the Data Fabric PMC control register, however. So when a user requests raw Data Fabric events (-e amd_df/event=0xYYY/), the two highest order bits get inadvertently set, changing the counter select to events that don't exist, and for which no counts are read. This patch changes the logic to write the L3 masks only when dealing with L3 PMC counters. AMD Family 16h and below Northbridge (NB) counters were not affected.

For example: perf record -e 'cycles:p' -a perf record -e 'cycles' -a The error message for spurious NMI: [June 21 15:38] Uhhuh. NMI received for unknown reason 30 on CPU 2. [ +0.000000] Do you have a strange power saving mode enabled? [ +0.000000] Dazed and confused, but trying to continue The bug was introduced by the following commit: commit 6f55967ad9d9 ("perf/x86/intel: Fix race in intel_pmu_disable_event()") The commit moves the intel_pmu_pebs_disable() after intel_pmu_disable_fixed(), which returns immediately. The related bit of PEBS_ENABLE MSR will never be cleared for the fixed counter. Then a non-PEBS event runs on the fixed counter, but the bit on PEBS_ENABLE is still set, which triggers spurious NMIs. Check and disable PEBS for fixed counters after intel_pmu_disable_fixed().

To not break this nice new feature let's mark 435 for clone3 as reserved on all architectures that do not yet implement it. Even if an architecture does not plan to implement it this ensures that new system calls coming after clone3 will have the same number on all architectures.

Overview - -Intel's IXP4xx network processor is a highly integrated SOC that -is targeted for network applications, though it has become popular -in industrial control and other areas due to low cost and power -consumption. The IXP4xx family currently consists of several processors -that support different network offload functions such as encryption, -routing, firewalling, etc. The IXP46x family is an updated version which -supports faster speeds, new memory and flash configurations, and more -integration such as an on-chip I2C controller. - -For more information on the various versions of the CPU, see: - - http://developer.intel.com/design/network/products/npfamily/ixp4xx.htm - -Intel also made the IXCP1100 CPU for sometime which is an IXP4xx -stripped of much of the network intelligence. - -2. Linux Support - -Linux currently supports the following features on the IXP4xx chips: - -- Dual serial ports -- PCI interface -- Flash access (MTD/JFFS) -- I2C through GPIO on IXP42x -- GPIO for input/output/interrupts - See arch/arm/mach-ixp4xx/include/mach/platform.h for access functions. -- Timers (watchdog, OS) - -The following components of the chips are not supported by Linux and -require the use of Intel's proprietary CSR software: - -- USB device interface -- Network interfaces (HSS, Utopia, NPEs, etc) -- Network offload functionality - -If you need to use any of the above, you need to download Intel's -software from: - - http://developer.intel.com/design/network/products/npfamily/ixp425.htm - -DO NOT POST QUESTIONS TO THE LINUX MAILING LISTS REGARDING THE PROPRIETARY -SOFTWARE. - -There are several websites that provide directions/pointers on using -Intel's software: - - http://sourceforge.net/projects/ixp4xx-osdg/ - Open Source Developer's Guide for using uClinux and the Intel libraries - -http://gatewaymaker.sourceforge.net/ - Simple one page summary of building a gateway using an IXP425 and Linux - -http://ixp425.sourceforge.net/ - ATM device driver for IXP425 that relies on Intel's libraries - -3. Known Issues/Limitations - -3a. Limited inbound PCI window - -The IXP4xx family allows for up to 256MB of memory but the PCI interface -can only expose 64MB of that memory to the PCI bus. This means that if -you are running with > 64MB, all PCI buffers outside of the accessible -range will be bounced using the routines in arch/arm/common/dmabounce.c. - -3b. Limited outbound PCI window - -IXP4xx provides two methods of accessing PCI memory space: - -1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB). - To access PCI via this space, we simply ioremap() the BAR - into the kernel and we can use the standard read[bwl]/write[bwl] - macros. This is the preffered method due to speed but it - limits the system to just 64MB of PCI memory. This can be - problamatic if using video cards and other memory-heavy devices. - -2) If > 64MB of memory space is required, the IXP4xx can be - configured to use indirect registers to access PCI This allows - for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. - The disadvantage of this is that every PCI access requires - three local register accesses plus a spinlock, but in some - cases the performance hit is acceptable. In addition, you cannot - mmap() PCI devices in this case due to the indirect nature - of the PCI window. - -By default, the direct method is used for performance reasons. If -you need more PCI memory, enable the IXP4XX_INDIRECT_PCI config option. - -3c. GPIO as Interrupts - -Currently the code only handles level-sensitive GPIO interrupts - -4. Supported platforms - -ADI Engineering Coyote Gateway Reference Platform -http://www.adiengineering.com/productsCoyote.html - - The ADI Coyote platform is reference design for those building - small residential/office gateways. One NPE is connected to a 10/100 - interface, one to 4-port 10/100 switch, and the third to and ADSL - interface. In addition, it also supports to POTs interfaces connected - via SLICs. Note that those are not supported by Linux ATM. Finally, - the platform has two mini-PCI slots used for 802.11[bga] cards. - Finally, there is an IDE port hanging off the expansion bus. - -Gateworks Avila Network Platform -http://www.gateworks.com/support/overview.php - - The Avila platform is basically and IXDP425 with the 4 PCI slots - replaced with mini-PCI slots and a CF IDE interface hanging off - the expansion bus. - -Intel IXDP425 Development Platform -http://www.intel.com/design/network/products/npfamily/ixdpg425.htm - - This is Intel's standard reference platform for the IXDP425 and is - also known as the Richfield board. It contains 4 PCI slots, 16MB - of flash, two 10/100 ports and one ADSL port. - -Intel IXDP465 Development Platform -http://www.intel.com/design/network/products/npfamily/ixdp465.htm - - This is basically an IXDP425 with an IXP465 and 32M of flash instead - of just 16. - -Intel IXDPG425 Development Platform - - This is basically and ADI Coyote board with a NEC EHCI controller - added. One issue with this board is that the mini-PCI slots only - have the 3.3v line connected, so you can't use a PCI to mini-PCI - adapter with an E100 card. So to NFS root you need to use either - the CSR or a WiFi card and a ramdisk that BOOTPs and then does - a pivot_root to NFS. - -Motorola PrPMC1100 Processor Mezanine Card -http://www.fountainsys.com - - The PrPMC1100 is based on the IXCP1100 and is meant to plug into - and IXP2400/2800 system to act as the system controller. It simply - contains a CPU and 16MB of flash on the board and needs to be - plugged into a carrier board to function. Currently Linux only - supports the Motorola PrPMC carrier board for this platform. - -5.

This doesn't have to be a real "IC"; indeed the -SA11x0 IRQs are handled by two separate "chip" structures, one for -GPIO0-10, and another for all the rest. It is just a container for -the various operations (maybe this'll change to a better name). -This structure has the following operations: - -struct irqchip { - /* - * Acknowledge the IRQ. - * If this is a level-based IRQ, then it is expected to mask the IRQ - * as well. - */ - void (*ack)(unsigned int irq); - /* - * Mask the IRQ in hardware. - */ - void (*mask)(unsigned int irq); - /* - * Unmask the IRQ in hardware. - */ - void (*unmask)(unsigned int irq); - /* - * Re-run the IRQ - */ - void (*rerun)(unsigned int irq); - /* - * Set the type of the IRQ. - */ - int (*type)(unsigned int irq, unsigned int, type); -}; - -ack - required. May be the same function as mask for IRQs - handled by do_level_IRQ. -mask - required. -unmask - required. -rerun - optional. Not required if you're using do_level_IRQ for all - IRQs that use this 'irqchip'. Generally expected to re-trigger - the hardware IRQ if possible. If not, may call the handler - directly. -type - optional. If you don't support changing the type of an IRQ, - it should be null so people can detect if they are unable to - set the IRQ type. - -For each IRQ, we keep the following information: - - - "disable" depth (number of disable_irq()s without enable_irq()s) - - flags indicating what we can do with this IRQ (valid, probe, - noautounmask) as before - - status of the IRQ (probing, enable, etc) - - chip - - per-IRQ handler - - irqaction structure list - -The handler can be one of the 3 standard handlers - "level", "edge" and -"simple", or your own specific handler if you need to do something special. - -The "level" handler is what we currently have - its pretty simple. -"edge" knows about the brokenness of such IRQ implementations - that you -need to leave the hardware IRQ enabled while processing it, and queueing -further IRQ events should the IRQ happen again while processing. The -"simple" handler is very basic, and does not perform any hardware -manipulation, nor state tracking. This is useful for things like the -SMC9196 and USAR above. - -So, what's changed? - -1. Machine implementations must not write to the irqdesc array. - -2. New functions to manipulate the irqdesc array. The first 4 are expected - to be useful only to machine specific code. The last is recommended to - only be used by machine specific code, but may be used in drivers if - absolutely necessary. - - set_irq_chip(irq,chip) - - Set the mask/unmask methods for handling this IRQ - - set_irq_handler(irq,handler) - - Set the handler for this IRQ (level, edge, simple) - - set_irq_chained_handler(irq,handler) - - Set a "chained" handler for this IRQ - automatically - enables this IRQ (eg, Neponset and SA1111 handlers). - - set_irq_flags(irq,flags) - - Set the valid/probe/noautoenable flags. - - set_irq_type(irq,type) - - Set active the IRQ edge(s)/level. This replaces the - SA1111 INTPOL manipulation, and the set_GPIO_IRQ_edge() - function. Type should be one of IRQ_TYPE_xxx defined in - - -3. set_GPIO_IRQ_edge() is obsolete, and should be replaced by set_irq_type. - -4. Direct access to SA1111 INTPOL is deprecated. Use set_irq_type instead. - -5. A handler is expected to perform any necessary acknowledgement of the - parent IRQ via the correct chip specific function. For instance, if - the SA1111 is directly connected to a SA1110 GPIO, then you should - acknowledge the SA1110 IRQ each time you re-read the SA1111 IRQ status. - -6. For any child which doesn't have its own IRQ enable/disable controls - (eg, SMC9196), the handler must mask or acknowledge the parent IRQ - while the child handler is called, and the child handler should be the - "simple" handler (not "edge" nor "level"). After the handler completes, - the parent IRQ should be unmasked, and the status of all children must - be re-checked for pending events. (see the Neponset IRQ handler for - details). - -7. fixup_irq() is gone, as is arch/arm/mach-*/include/mach/irq.h - -Please note that this will not solve all problems - some of them are -hardware based. Mixing level-based and edge-based IRQs on the same -parent signal (eg neponset) is one such area where a software based -solution can't provide the full answer to low IRQ latency. - diff --git a/Documentation/arm/Marvell/README b/Documentation/arm/Marvell/README deleted file mode 100644 index 56ada27c53be..000000000000 --- a/Documentation/arm/Marvell/README +++ /dev/null @@ -1,395 +0,0 @@ -ARM Marvell SoCs -================ - -This document lists all the ARM Marvell SoCs that are currently -supported in mainline by the Linux kernel.

In addition to -modelling the hardware overlays, omapdss supports virtual overlays and overlay -managers. These can be used when updating a display with CPU or system DMA. - -omapdss driver support for audio --------------------------------- -There exist several display technologies and standards that support audio as -well. Hence, it is relevant to update the DSS device driver to provide an audio -interface that may be used by an audio driver or any other driver interested in -the functionality. - -The audio_enable function is intended to prepare the relevant -IP for playback (e.g., enabling an audio FIFO, taking in/out of reset -some IP, enabling companion chips, etc). It is intended to be called before -audio_start. The audio_disable function performs the reverse operation and is -intended to be called after audio_stop. - -While a given DSS device driver may support audio, it is possible that for -certain configurations audio is not supported (e.g., an HDMI display using a -VESA video timing). The audio_supported function is intended to query whether -the current configuration of the display supports audio. - -The audio_config function is intended to configure all the relevant audio -parameters of the display. In order to make the function independent of any -specific DSS device driver, a struct omap_dss_audio is defined. Its purpose -is to contain all the required parameters for audio configuration. At the -moment, such structure contains pointers to IEC-60958 channel status word -and CEA-861 audio infoframe structures. This should be enough to support -HDMI and DisplayPort, as both are based on CEA-861 and IEC-60958. - -The audio_enable/disable, audio_config and audio_supported functions could be -implemented as functions that may sleep. Hence, they should not be called -while holding a spinlock or a readlock. - -The audio_start/audio_stop function is intended to effectively start/stop audio -playback after the configuration has taken place. These functions are designed -to be used in an atomic context. Hence, audio_start should return quickly and be -called only after all the needed resources for audio playback (audio FIFOs, -DMA channels, companion chips, etc) have been enabled to begin data transfers. -audio_stop is designed to only stop the audio transfers. The resources used -for playback are released using audio_disable. - -The enum omap_dss_audio_state may be used to help the implementations of -the interface to keep track of the audio state. The initial state is _DISABLED; -then, the state transitions to _CONFIGURED, and then, when it is ready to -play audio, to _ENABLED.

They register -themselves to the DSS driver. - -omapfb driver -------------- - -The omapfb driver implements arbitrary number of standard linux framebuffers. -These framebuffers can be routed flexibly to any overlays, thus allowing very -dynamic display architecture. - -The driver exports some omapfb specific ioctls, which are compatible with the -ioctls in the old driver. - -The rest of the non standard features are exported via sysfs. Whether the final -implementation will use sysfs, or ioctls, is still open. - -V4L2 drivers ------------- - -V4L2 is being implemented in TI. - -From omapdss point of view the V4L2 drivers should be similar to framebuffer -driver. - -Architecture --------------------- - -Some clarification what the different components do: - - - Framebuffer is a memory area inside OMAP's SRAM/SDRAM that contains the - pixel data for the image. Framebuffer has width and height and color - depth. - - Overlay defines where the pixels are read from and where they go on the - screen. The overlay may be smaller than framebuffer, thus displaying only - part of the framebuffer. The position of the overlay may be changed if - the overlay is smaller than the display. - - Overlay manager combines the overlays in to one image and feeds them to - display. - - Display is the actual physical display device. - -A framebuffer can be connected to multiple overlays to show the same pixel data -on all of the overlays. Note that in this case the overlay input sizes must be -the same, but, in case of video overlays, the output size can be different. Any -framebuffer can be connected to any overlay. - -An overlay can be connected to one overlay manager. Also DISPC overlays can be -connected only to DISPC overlay managers, and virtual overlays can be only -connected to virtual overlays. - -An overlay manager can be connected to one display. There are certain -restrictions which kinds of displays an overlay manager can be connected: - - - DISPC TV overlay manager can be only connected to TV display. - - Virtual overlay managers can only be connected to DBI or DSI displays. - - DISPC LCD overlay manager can be connected to all displays, except TV - display. - -Sysfs ------ -The sysfs interface is mainly used for testing.

Drivers should use the following idiom: - - if (pdata->set_max_dev_wakeup_lat) - (*pdata->set_max_dev_wakeup_lat)(dev, t); - -The most common usage of these functions will probably be to specify -the maximum time from when an interrupt occurs, to when the device -becomes accessible. To accomplish this, driver writers should use the -set_max_mpu_wakeup_lat() function to constrain the MPU wakeup -latency, and the set_max_dev_wakeup_lat() function to constrain the -device wakeup latency (from clk_enable() to accessibility). For -example, - - /* Limit MPU wakeup latency */ - if (pdata->set_max_mpu_wakeup_lat) - (*pdata->set_max_mpu_wakeup_lat)(dev, tc); - - /* Limit device powerdomain wakeup latency */ - if (pdata->set_max_dev_wakeup_lat) - (*pdata->set_max_dev_wakeup_lat)(dev, td); - - /* total wakeup latency in this example: (tc + td) */ - -The PM parameters can be overwritten by calling the function again -with the new value. The settings can be removed by calling the -function with a t argument of -1 (except in the case of -set_max_bus_tput(), which should be called with an r argument of 0). - -The fifth function above, omap_pm_get_dev_context_loss_count(), -is intended as an optimization to allow drivers to determine whether the -device has lost its internal context. If context has been lost, the -driver must restore its internal context before proceeding. - - -Other specialized interface functions -------------------------------------- - -The five functions listed above are intended to be usable by any -device driver.

For more information, see - http://www.arm.linux.org.uk/developer/patches/info.php Always include some - explanation as to what the patch does and why it is needed. - - Bug reports should be sent to linux-arm-kernel@lists.arm.linux.org.uk, - or submitted through the web form at - http://www.arm.linux.org.uk/developer/ - - When sending bug reports, please ensure that they contain all relevant - information, eg. the kernel messages that were printed before/during - the problem, what you were doing, etc. - - -Include files -------------- - - Several new include directories have been created under include/asm-arm, - which are there to reduce the clutter in the top-level directory. These - directories, and their purpose is listed below: - - arch-* machine/platform specific header files - hardware driver-internal ARM specific data structures/definitions - mach descriptions of generic ARM to specific machine interfaces - proc-* processor dependent header files (currently only two - categories) - - -Machine/Platform support ------------------------- - - The ARM tree contains support for a lot of different machine types. To - continue supporting these differences, it has become necessary to split - machine-specific parts by directory. For this, the machine category is - used to select which directories and files get included (we will use - $(MACHINE) to refer to the category) - - To this end, we now have arch/arm/mach-$(MACHINE) directories which are - designed to house the non-driver files for a particular machine (eg, PCI, - memory management, architecture definitions etc). For all future - machines, there should be a corresponding arch/arm/mach-$(MACHINE)/include/mach - directory. - - -Modules -------- - - Although modularisation is supported (and required for the FP emulator), - each module on an ARM2/ARM250/ARM3 machine when is loaded will take - memory up to the next 32k boundary due to the size of the pages. - Therefore, is modularisation on these machines really worth it? - - However, ARM6 and up machines allow modules to take multiples of 4k, and - as such Acorn RiscPCs and other architectures using these processors can - make good use of modularisation. - - -ADFS Image files ----------------- - - You can access image files on your ADFS partitions by mounting the ADFS - partition, and then using the loopback device driver. You must have - losetup installed. - - Please note that the PCEmulator DOS partitions have a partition table at - the start, and as such, you will have to give '-o offset' to losetup. - - -Request to developers ---------------------- - - When writing device drivers which include a separate assembler file, please - include it in with the C file, and not the arch/arm/lib directory. This - allows the driver to be compiled as a loadable module without requiring - half the code to be compiled into the kernel image. - - In general, try to avoid using assembler unless it is really necessary. It - makes drivers far less easy to port to other hardware. - - -ST506 hard drives ------------------ - - The ST506 hard drive controllers seem to be working fine (if a little - slowly). At the moment they will only work off the controllers on an - A4x0's motherboard, but for it to work off a Podule just requires - someone with a podule to add the addresses for the IRQ mask and the - HDC base to the source. - - As of 31/3/96 it works with two drives (you should get the ADFS - *configure harddrive set to 2). I've got an internal 20MB and a great - big external 5.25" FH 64MB drive (who could ever want more :-) ). - - I've just got 240K/s off it (a dd with bs=128k); thats about half of what - RiscOS gets; but it's a heck of a lot better than the 50K/s I was getting - last week :-) - - Known bug: Drive data errors can cause a hang; including cases where - the controller has fixed the error using ECC. (Possibly ONLY - in that case...hmm). - - -1772 Floppy ------------ - This also seems to work OK, but hasn't been stressed much lately. It - hasn't got any code for disc change detection in there at the moment which - could be a bit of a problem! Suggestions on the correct way to do this - are welcome. - - -CONFIG_MACH_ and CONFIG_ARCH_ ------------------------------ - A change was made in 2003 to the macro names for new machines. - Historically, CONFIG_ARCH_ was used for the bonafide architecture, - e.g. SA1100, as well as implementations of the architecture, - e.g. Assabet. It was decided to change the implementation macros - to read CONFIG_MACH_ for clarity. Moreover, a retroactive fixup has - not been made because it would complicate patching. - - Previous registrations may be found online. - - - -Kernel entry (head.S) --------------------------- - The initial entry into the kernel is via head.S, which uses machine - independent code. The machine is selected by the value of 'r1' on - entry, which must be kept unique. - - Due to the large number of machines which the ARM port of Linux provides - for, we have a method to manage this which ensures that we don't end up - duplicating large amounts of code. - - We group machine (or platform) support code into machine classes. A - class typically based around one or more system on a chip devices, and - acts as a natural container around the actual implementations. These - classes are given directories - arch/arm/mach- and - arch/arm/mach- - which contain the source files to/include/mach - support the machine class. This directories also contain any machine - specific supporting code. - - For example, the SA1100 class is based upon the SA1100 and SA1110 SoC - devices, and contains the code to support the way the on-board and off- - board devices are used, or the device is setup, and provides that - machine specific "personality." - - For platforms that support device tree (DT), the machine selection is - controlled at runtime by passing the device tree blob to the kernel. At - compile-time, support for the machine type must be selected. This allows for - a single multiplatform kernel build to be used for several machine types. - - For platforms that do not use device tree, this machine selection is - controlled by the machine type ID, which acts both as a run-time and a - compile-time code selection method. You can register a new machine via the - web site at: - - - - Note: Please do not register a machine type for DT-only platforms.

These defines are used to tell - the GPIO functions which pin is to be used. - - With the conversion to gpiolib, there is no longer a direct conversion - from gpio pin number to register base address as in earlier kernels.

This can be configured by the following - function: - - void s3c_gpio_setpull(unsigned int pin, unsigned int to); - - Where the to value is S3C_GPIO_PULL_NONE to set the pull-up off, - and S3C_GPIO_PULL_UP to enable the specified pull-up. Any other - values are currently undefined. - - -Getting and setting the state of a PIN --------------------------------------- - - These calls are now implemented by the relevant gpiolib calls, convert - your board or driver to use gpiolib. - - -Getting the IRQ number associated with a PIN --------------------------------------------- - - A standard gpiolib function can map the given pin number to an IRQ - number to pass to the IRQ system. - - int gpio_to_irq(unsigned int pin); - - Note, not all pins have an IRQ. - - -Author -------- - -Ben Dooks, 03 October 2004 -Copyright 2004 Ben Dooks, Simtec Electronics diff --git a/Documentation/arm/Samsung-S3C24XX/H1940.txt b/Documentation/arm/Samsung-S3C24XX/H1940.txt deleted file mode 100644 index b738859b1fc0..000000000000 --- a/Documentation/arm/Samsung-S3C24XX/H1940.txt +++ /dev/null @@ -1,40 +0,0 @@ - HP IPAQ H1940 - ============= - -http://www.handhelds.org/projects/h1940.html - -Introduction ------------- - - The HP H1940 is a S3C2410 based handheld device, with - bluetooth connectivity. - - -Support -------- - - A variety of information is available - - handhelds.org project page: - - http://www.handhelds.org/projects/h1940.html - - handhelds.org wiki page: - - http://handhelds.org/moin/moin.cgi/HpIpaqH1940 - - Herbert Pötzl pages: - - http://vserver.13thfloor.at/H1940/ - - -Maintainers ------------ - - This project is being maintained and developed by a variety - of people, including Ben Dooks, Arnaud Patard, and Herbert Pötzl. - - Thanks to the many others who have also provided support. - - -(c) 2005 Ben Dooks diff --git a/Documentation/arm/Samsung-S3C24XX/NAND.txt b/Documentation/arm/Samsung-S3C24XX/NAND.txt deleted file mode 100644 index bc478a3409b8..000000000000 --- a/Documentation/arm/Samsung-S3C24XX/NAND.txt +++ /dev/null @@ -1,30 +0,0 @@ - S3C24XX NAND Support - ==================== - -Introduction ------------- - -Small Page NAND ---------------- - -The driver uses a 512 byte (1 page) ECC code for this setup.

These + directories, and their purpose is listed below: + + ============= ========================================================== + `arch-*` machine/platform specific header files + `hardware` driver-internal ARM specific data structures/definitions + `mach` descriptions of generic ARM to specific machine interfaces + `proc-*` processor dependent header files (currently only two + categories) + ============= ========================================================== + + +Machine/Platform support +------------------------ + + The ARM tree contains support for a lot of different machine types. To + continue supporting these differences, it has become necessary to split + machine-specific parts by directory. For this, the machine category is + used to select which directories and files get included (we will use + $(MACHINE) to refer to the category) + + To this end, we now have arch/arm/mach-$(MACHINE) directories which are + designed to house the non-driver files for a particular machine (eg, PCI, + memory management, architecture definitions etc). For all future + machines, there should be a corresponding arch/arm/mach-$(MACHINE)/include/mach + directory. + + +Modules +------- + + Although modularisation is supported (and required for the FP emulator), + each module on an ARM2/ARM250/ARM3 machine when is loaded will take + memory up to the next 32k boundary due to the size of the pages. + Therefore, is modularisation on these machines really worth it? + + However, ARM6 and up machines allow modules to take multiples of 4k, and + as such Acorn RiscPCs and other architectures using these processors can + make good use of modularisation. + + +ADFS Image files +---------------- + + You can access image files on your ADFS partitions by mounting the ADFS + partition, and then using the loopback device driver. You must have + losetup installed. + + Please note that the PCEmulator DOS partitions have a partition table at + the start, and as such, you will have to give '-o offset' to losetup. + + +Request to developers +--------------------- + + When writing device drivers which include a separate assembler file, please + include it in with the C file, and not the arch/arm/lib directory. This + allows the driver to be compiled as a loadable module without requiring + half the code to be compiled into the kernel image. + + In general, try to avoid using assembler unless it is really necessary. It + makes drivers far less easy to port to other hardware. + + +ST506 hard drives +----------------- + + The ST506 hard drive controllers seem to be working fine (if a little + slowly). At the moment they will only work off the controllers on an + A4x0's motherboard, but for it to work off a Podule just requires + someone with a podule to add the addresses for the IRQ mask and the + HDC base to the source. + + As of 31/3/96 it works with two drives (you should get the ADFS + `*configure` harddrive set to 2). I've got an internal 20MB and a great + big external 5.25" FH 64MB drive (who could ever want more :-) ). + + I've just got 240K/s off it (a dd with bs=128k); thats about half of what + RiscOS gets; but it's a heck of a lot better than the 50K/s I was getting + last week :-) + + Known bug: Drive data errors can cause a hang; including cases where + the controller has fixed the error using ECC. (Possibly ONLY + in that case...hmm). + + +1772 Floppy +----------- + This also seems to work OK, but hasn't been stressed much lately. It + hasn't got any code for disc change detection in there at the moment which + could be a bit of a problem! Suggestions on the correct way to do this + are welcome. + + +`CONFIG_MACH_` and `CONFIG_ARCH_` +--------------------------------- + A change was made in 2003 to the macro names for new machines. + Historically, `CONFIG_ARCH_` was used for the bonafide architecture, + e.g. SA1100, as well as implementations of the architecture, + e.g. Assabet. It was decided to change the implementation macros + to read `CONFIG_MACH_` for clarity. Moreover, a retroactive fixup has + not been made because it would complicate patching. + + Previous registrations may be found online. + + + +Kernel entry (head.S) +--------------------- + The initial entry into the kernel is via head.S, which uses machine + independent code. The machine is selected by the value of 'r1' on + entry, which must be kept unique. + + Due to the large number of machines which the ARM port of Linux provides + for, we have a method to manage this which ensures that we don't end up + duplicating large amounts of code. + + We group machine (or platform) support code into machine classes. A + class typically based around one or more system on a chip devices, and + acts as a natural container around the actual implementations. These + classes are given directories - arch/arm/mach- and + arch/arm/mach- - which contain the source files to/include/mach + support the machine class. This directories also contain any machine + specific supporting code. + + For example, the SA1100 class is based upon the SA1100 and SA1110 SoC + devices, and contains the code to support the way the on-board and off- + board devices are used, or the device is setup, and provides that + machine specific "personality." + + For platforms that support device tree (DT), the machine selection is + controlled at runtime by passing the device tree blob to the kernel.

This allows for + a single multiplatform kernel build to be used for several machine types. + + For platforms that do not use device tree, this machine selection is + controlled by the machine type ID, which acts both as a run-time and a + compile-time code selection method.

The boot loader is expected +to initialise various devices, and eventually call the Linux kernel, +passing information to the kernel. + +Essentially, the boot loader should provide (as a minimum) the +following: + +1. Setup and initialise the RAM. +2. Initialise one serial port. +3. Detect the machine type. +4. Setup the kernel tagged list. +5. Load initramfs. +6. Call the kernel image. + + +1. Setup and initialise RAM +--------------------------- + +Existing boot loaders: + MANDATORY +New boot loaders: + MANDATORY + +The boot loader is expected to find and initialise all RAM that the +kernel will use for volatile data storage in the system. It performs +this in a machine dependent manner. (It may use internal algorithms +to automatically locate and size all RAM, or it may use knowledge of +the RAM in the machine, or any other method the boot loader designer +sees fit.) + + +2. Initialise one serial port +----------------------------- + +Existing boot loaders: + OPTIONAL, RECOMMENDED +New boot loaders: + OPTIONAL, RECOMMENDED + +The boot loader should initialise and enable one serial port on the +target. This allows the kernel serial driver to automatically detect +which serial port it should use for the kernel console (generally +used for debugging purposes, or communication with the target.) + +As an alternative, the boot loader can pass the relevant 'console=' +option to the kernel via the tagged lists specifying the port, and +serial format options as described in + + Documentation/admin-guide/kernel-parameters.rst. + + +3. Detect the machine type +-------------------------- + +Existing boot loaders: + OPTIONAL +New boot loaders: + MANDATORY except for DT-only platforms + +The boot loader should detect the machine type its running on by some +method. Whether this is a hard coded value or some algorithm that +looks at the connected hardware is beyond the scope of this document. +The boot loader must ultimately be able to provide a MACH_TYPE_xxx +value to the kernel. (see linux/arch/arm/tools/mach-types). This +should be passed to the kernel in register r1. + +For DT-only platforms, the machine type will be determined by device +tree. set the machine type to all ones (~0). This is not strictly +necessary, but assures that it will not match any existing types. + +4. Setup boot data +------------------ + +Existing boot loaders: + OPTIONAL, HIGHLY RECOMMENDED +New boot loaders: + MANDATORY + +The boot loader must provide either a tagged list or a dtb image for +passing configuration data to the kernel. The physical address of the +boot data is passed to the kernel in register r2. + +4a. Setup the kernel tagged list +-------------------------------- + +The boot loader must create and initialise the kernel tagged list. +A valid tagged list starts with ATAG_CORE and ends with ATAG_NONE. +The ATAG_CORE tag may or may not be empty. An empty ATAG_CORE tag +has the size field set to '2' (0x00000002). The ATAG_NONE must set +the size field to zero. + +Any number of tags can be placed in the list. It is undefined +whether a repeated tag appends to the information carried by the +previous tag, or whether it replaces the information in its +entirety; some tags behave as the former, others the latter. + +The boot loader must pass at a minimum the size and location of +the system memory, and root filesystem location. Therefore, the +minimum tagged list should look:: + + +-----------+ + base -> | ATAG_CORE | | + +-----------+ | + | ATAG_MEM | | increasing address + +-----------+ | + | ATAG_NONE | | + +-----------+ v + +The tagged list should be stored in system RAM. + +The tagged list must be placed in a region of memory where neither +the kernel decompressor nor initrd 'bootp' program will overwrite +it. The recommended placement is in the first 16KiB of RAM. + +4b. Setup the device tree +------------------------- + +The boot loader must load a device tree image (dtb) into system ram +at a 64bit aligned address and initialize it with the boot data. The +dtb format is documented in Documentation/devicetree/booting-without-of.txt. +The kernel will look for the dtb magic value of 0xd00dfeed at the dtb +physical address to determine if a dtb has been passed instead of a +tagged list. + +The boot loader must pass at a minimum the size and location of the +system memory, and the root filesystem location. The dtb must be +placed in a region of memory where the kernel decompressor will not +overwrite it, while remaining within the region which will be covered +by the kernel's low-memory mapping. + +A safe location is just above the 128MiB boundary from start of RAM. + +5. Load initramfs. +------------------ + +Existing boot loaders: + OPTIONAL +New boot loaders: + OPTIONAL + +If an initramfs is in use then, as with the dtb, it must be placed in +a region of memory where the kernel decompressor will not overwrite it +while also with the region which will be covered by the kernel's +low-memory mapping. + +A safe location is just above the device tree blob which itself will +be loaded just above the 128MiB boundary from the start of RAM as +recommended above. + +6. Calling the kernel image +--------------------------- + +Existing boot loaders: + MANDATORY +New boot loaders: + MANDATORY + +There are two options for calling the kernel zImage.

Each MMU TLB variant is now handled completely separately - +we have TLB v3, TLB v4 (without write buffer), TLB v4 (with write buffer), +and finally TLB v4 (with write buffer, with I TLB invalidate entry). +There is more assembly code inside each of these functions, mainly to +allow more flexible TLB handling for the future. + +Secondly, the IRQ subsystem. + +The 2.5 kernels will be having major changes to the way IRQs are handled. +Unfortunately, this means that machine types that touch the irq_desc[] +array (basically all machine types) will break, and this means every +machine type that we currently have. + +Lets take an example. On the Assabet with Neponset, we have:: + + GPIO25 IRR:2 + SA1100 ------------> Neponset -----------> SA1111 + IIR:1 + -----------> USAR + IIR:0 + -----------> SMC9196 + +The way stuff currently works, all SA1111 interrupts are mutually +exclusive of each other - if you're processing one interrupt from the +SA1111 and another comes in, you have to wait for that interrupt to +finish processing before you can service the new interrupt. Eg, an +IDE PIO-based interrupt on the SA1111 excludes all other SA1111 and +SMC9196 interrupts until it has finished transferring its multi-sector +data, which can be a long time. Note also that since we loop in the +SA1111 IRQ handler, SA1111 IRQs can hold off SMC9196 IRQs indefinitely. + + +The new approach brings several new ideas... + +We introduce the concept of a "parent" and a "child". For example, +to the Neponset handler, the "parent" is GPIO25, and the "children"d +are SA1111, SMC9196 and USAR. + +We also bring the idea of an IRQ "chip" (mainly to reduce the size of +the irqdesc array). This doesn't have to be a real "IC"; indeed the +SA11x0 IRQs are handled by two separate "chip" structures, one for +GPIO0-10, and another for all the rest. It is just a container for +the various operations (maybe this'll change to a better name). +This structure has the following operations:: + + struct irqchip { + /* + * Acknowledge the IRQ. + * If this is a level-based IRQ, then it is expected to mask the IRQ + * as well. + */ + void (*ack)(unsigned int irq); + /* + * Mask the IRQ in hardware. + */ + void (*mask)(unsigned int irq); + /* + * Unmask the IRQ in hardware. + */ + void (*unmask)(unsigned int irq); + /* + * Re-run the IRQ + */ + void (*rerun)(unsigned int irq); + /* + * Set the type of the IRQ. + */ + int (*type)(unsigned int irq, unsigned int, type); + }; + +ack + - required. May be the same function as mask for IRQs + handled by do_level_IRQ. +mask + - required. +unmask + - required. +rerun + - optional. Not required if you're using do_level_IRQ for all + IRQs that use this 'irqchip'. Generally expected to re-trigger + the hardware IRQ if possible. If not, may call the handler + directly. +type + - optional. If you don't support changing the type of an IRQ, + it should be null so people can detect if they are unable to + set the IRQ type. + +For each IRQ, we keep the following information: + + - "disable" depth (number of disable_irq()s without enable_irq()s) + - flags indicating what we can do with this IRQ (valid, probe, + noautounmask) as before + - status of the IRQ (probing, enable, etc) + - chip + - per-IRQ handler + - irqaction structure list + +The handler can be one of the 3 standard handlers - "level", "edge" and +"simple", or your own specific handler if you need to do something special. + +The "level" handler is what we currently have - its pretty simple. +"edge" knows about the brokenness of such IRQ implementations - that you +need to leave the hardware IRQ enabled while processing it, and queueing +further IRQ events should the IRQ happen again while processing. The +"simple" handler is very basic, and does not perform any hardware +manipulation, nor state tracking. This is useful for things like the +SMC9196 and USAR above. + +So, what's changed? +=================== + +1. Machine implementations must not write to the irqdesc array. + +2. New functions to manipulate the irqdesc array. The first 4 are expected + to be useful only to machine specific code. The last is recommended to + only be used by machine specific code, but may be used in drivers if + absolutely necessary. + + set_irq_chip(irq,chip) + Set the mask/unmask methods for handling this IRQ + + set_irq_handler(irq,handler) + Set the handler for this IRQ (level, edge, simple) + + set_irq_chained_handler(irq,handler) + Set a "chained" handler for this IRQ - automatically + enables this IRQ (eg, Neponset and SA1111 handlers). + + set_irq_flags(irq,flags) + Set the valid/probe/noautoenable flags. + + set_irq_type(irq,type) + Set active the IRQ edge(s)/level. This replaces the + SA1111 INTPOL manipulation, and the set_GPIO_IRQ_edge() + function. Type should be one of IRQ_TYPE_xxx defined in + + +3. set_GPIO_IRQ_edge() is obsolete, and should be replaced by set_irq_type. + +4. Direct access to SA1111 INTPOL is deprecated. Use set_irq_type instead. + +5. A handler is expected to perform any necessary acknowledgement of the + parent IRQ via the correct chip specific function. For instance, if + the SA1111 is directly connected to a SA1110 GPIO, then you should + acknowledge the SA1110 IRQ each time you re-read the SA1111 IRQ status. + +6. For any child which doesn't have its own IRQ enable/disable controls + (eg, SMC9196), the handler must mask or acknowledge the parent IRQ + while the child handler is called, and the child handler should be the + "simple" handler (not "edge" nor "level"). After the handler completes, + the parent IRQ should be unmasked, and the status of all children must + be re-checked for pending events. (see the Neponset IRQ handler for + details). + +7. fixup_irq() is gone, as is `arch/arm/mach-*/include/mach/irq.h` + +Please note that this will not solve all problems - some of them are +hardware based.

Overview + +Intel's IXP4xx network processor is a highly integrated SOC that +is targeted for network applications, though it has become popular +in industrial control and other areas due to low cost and power +consumption. The IXP4xx family currently consists of several processors +that support different network offload functions such as encryption, +routing, firewalling, etc. The IXP46x family is an updated version which +supports faster speeds, new memory and flash configurations, and more +integration such as an on-chip I2C controller. + +For more information on the various versions of the CPU, see: + + http://developer.intel.com/design/network/products/npfamily/ixp4xx.htm + +Intel also made the IXCP1100 CPU for sometime which is an IXP4xx +stripped of much of the network intelligence. + +2.

Known Issues/Limitations + +3a. Limited inbound PCI window + +The IXP4xx family allows for up to 256MB of memory but the PCI interface +can only expose 64MB of that memory to the PCI bus. This means that if +you are running with > 64MB, all PCI buffers outside of the accessible +range will be bounced using the routines in arch/arm/common/dmabounce.c. + +3b. Limited outbound PCI window + +IXP4xx provides two methods of accessing PCI memory space: + +1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB). + To access PCI via this space, we simply ioremap() the BAR + into the kernel and we can use the standard read[bwl]/write[bwl] + macros. This is the preffered method due to speed but it + limits the system to just 64MB of PCI memory. This can be + problamatic if using video cards and other memory-heavy devices. + +2) If > 64MB of memory space is required, the IXP4xx can be + configured to use indirect registers to access PCI This allows + for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. + The disadvantage of this is that every PCI access requires + three local register accesses plus a spinlock, but in some + cases the performance hit is acceptable. In addition, you cannot + mmap() PCI devices in this case due to the indirect nature + of the PCI window. + +By default, the direct method is used for performance reasons.

However, for performance reasons, the NEON/VFP +register file is not preserved and restored at every context switch or taken +exception like the normal register file is, so some manual intervention is +required. Furthermore, special care is required for code that may sleep [i.e., +may call schedule()], as NEON or VFP instructions will be executed in a +non-preemptible section for reasons outlined below. + + +Lazy preserve and restore +------------------------- +The NEON/VFP register file is managed using lazy preserve (on UP systems) and +lazy restore (on both SMP and UP systems). This means that the register file is +kept 'live', and is only preserved and restored when multiple tasks are +contending for the NEON/VFP unit (or, in the SMP case, when a task migrates to +another core). Lazy restore is implemented by disabling the NEON/VFP unit after +every context switch, resulting in a trap when subsequently a NEON/VFP +instruction is issued, allowing the kernel to step in and perform the restore if +necessary. + +Any use of the NEON/VFP unit in kernel mode should not interfere with this, so +it is required to do an 'eager' preserve of the NEON/VFP register file, and +enable the NEON/VFP unit explicitly so no exceptions are generated on first +subsequent use. This is handled by the function kernel_neon_begin(), which +should be called before any kernel mode NEON or VFP instructions are issued. +Likewise, the NEON/VFP unit should be disabled again after use to make sure user +mode will hit the lazy restore trap upon next use. This is handled by the +function kernel_neon_end(). + + +Interruptions in kernel mode +---------------------------- +For reasons of performance and simplicity, it was decided that there shall be no +preserve/restore mechanism for the kernel mode NEON/VFP register contents. This +implies that interruptions of a kernel mode NEON section can only be allowed if +they are guaranteed not to touch the NEON/VFP registers. For this reason, the +following rules and restrictions apply in the kernel: +* NEON/VFP code is not allowed in interrupt context; +* NEON/VFP code is not allowed to sleep; +* NEON/VFP code is executed with preemption disabled. + +If latency is a concern, it is possible to put back to back calls to +kernel_neon_end() and kernel_neon_begin() in places in your code where none of +the NEON registers are live. (Additional calls to kernel_neon_begin() should be +reasonably cheap if no context switch occurred in the meantime) + + +VFP and support code +-------------------- +Earlier versions of VFP (prior to version 3) rely on software support for things +like IEEE-754 compliant underflow handling etc. When the VFP unit needs such +software assistance, it signals the kernel by raising an undefined instruction +exception. The kernel responds by inspecting the VFP control registers and the +current instruction and arguments, and emulates the instruction in software. + +Such software assistance is currently not implemented for VFP instructions +executed in kernel mode. If such a condition is encountered, the kernel will +fail and generate an OOPS. + + +Separating NEON code from ordinary code +--------------------------------------- +The compiler is not aware of the special significance of kernel_neon_begin() and +kernel_neon_end(), i.e., that it is only allowed to issue NEON/VFP instructions +between calls to these respective functions.

However, for performance reasons, the NEON/VFP -register file is not preserved and restored at every context switch or taken -exception like the normal register file is, so some manual intervention is -required. Furthermore, special care is required for code that may sleep [i.e., -may call schedule()], as NEON or VFP instructions will be executed in a -non-preemptible section for reasons outlined below. - - -Lazy preserve and restore -------------------------- -The NEON/VFP register file is managed using lazy preserve (on UP systems) and -lazy restore (on both SMP and UP systems). This means that the register file is -kept 'live', and is only preserved and restored when multiple tasks are -contending for the NEON/VFP unit (or, in the SMP case, when a task migrates to -another core). Lazy restore is implemented by disabling the NEON/VFP unit after -every context switch, resulting in a trap when subsequently a NEON/VFP -instruction is issued, allowing the kernel to step in and perform the restore if -necessary. - -Any use of the NEON/VFP unit in kernel mode should not interfere with this, so -it is required to do an 'eager' preserve of the NEON/VFP register file, and -enable the NEON/VFP unit explicitly so no exceptions are generated on first -subsequent use. This is handled by the function kernel_neon_begin(), which -should be called before any kernel mode NEON or VFP instructions are issued. -Likewise, the NEON/VFP unit should be disabled again after use to make sure user -mode will hit the lazy restore trap upon next use. This is handled by the -function kernel_neon_end(). - - -Interruptions in kernel mode ----------------------------- -For reasons of performance and simplicity, it was decided that there shall be no -preserve/restore mechanism for the kernel mode NEON/VFP register contents. This -implies that interruptions of a kernel mode NEON section can only be allowed if -they are guaranteed not to touch the NEON/VFP registers. For this reason, the -following rules and restrictions apply in the kernel: -* NEON/VFP code is not allowed in interrupt context; -* NEON/VFP code is not allowed to sleep; -* NEON/VFP code is executed with preemption disabled. - -If latency is a concern, it is possible to put back to back calls to -kernel_neon_end() and kernel_neon_begin() in places in your code where none of -the NEON registers are live. (Additional calls to kernel_neon_begin() should be -reasonably cheap if no context switch occurred in the meantime) - - -VFP and support code --------------------- -Earlier versions of VFP (prior to version 3) rely on software support for things -like IEEE-754 compliant underflow handling etc. When the VFP unit needs such -software assistance, it signals the kernel by raising an undefined instruction -exception. The kernel responds by inspecting the VFP control registers and the -current instruction and arguments, and emulates the instruction in software. - -Such software assistance is currently not implemented for VFP instructions -executed in kernel mode. If such a condition is encountered, the kernel will -fail and generate an OOPS. - - -Separating NEON code from ordinary code ---------------------------------------- -The compiler is not aware of the special significance of kernel_neon_begin() and -kernel_neon_end(), i.e., that it is only allowed to issue NEON/VFP instructions -between calls to these respective functions. Furthermore, GCC may generate NEON -instructions of its own at -O3 level if -mfpu=neon is selected, and even if the -kernel is currently compiled at -O2, future changes may result in NEON/VFP -instructions appearing in unexpected places if no special care is taken. - -Therefore, the recommended and only supported way of using NEON/VFP in the -kernel is by adhering to the following rules: -* isolate the NEON code in a separate compilation unit and compile it with - '-march=armv7-a -mfpu=neon -mfloat-abi=softfp'; -* issue the calls to kernel_neon_begin(), kernel_neon_end() as well as the calls - into the unit containing the NEON code from a compilation unit which is *not* - built with the GCC flag '-mfpu=neon' set. - -As the kernel is compiled with '-msoft-float', the above will guarantee that -both NEON and VFP instructions will only ever appear in designated compilation -units at any optimization level. - - -NEON assembler --------------- -NEON assembler is supported with no additional caveats as long as the rules -above are followed. - - -NEON code generated by GCC --------------------------- -The GCC option -ftree-vectorize (implied by -O3) tries to exploit implicit -parallelism, and generates NEON code from ordinary C source code.

According to Alan Cox, this is a +bad idea to configure it out, but Russell King has some good reasons for +doing so on some f***ed up ARM architectures like the EBSA110. However +this is not the case on many design I'm aware of, like all SA11x0 based +ones. + +Of course this is a bad idea to rely on the alignment trap to perform +unaligned memory access in general. If those access are predictable, you +are better to use the macros provided by include/asm/unaligned.h. The +alignment trap can fixup misaligned access for the exception cases, but at +a high performance cost. It better be rare. + +Now for user space applications, it is possible to configure the alignment +trap to SIGBUS any code performing unaligned access (good for debugging bad +code), or even fixup the access by software like for kernel code. The later +mode isn't recommended for performance reasons (just think about the +floating point emulation that works about the same way). Fix your code +instead! + +Please note that randomly changing the behaviour without good thought is +real bad - it changes the behaviour of all unaligned instructions in user +space, and might cause programs to fail unexpectedly. + +To change the alignment trap behavior, simply echo a number into +/proc/cpu/alignment. The number is made up from various bits: + +=== ======================================================== +bit behavior when set +=== ======================================================== +0 A user process performing an unaligned memory access + will cause the kernel to print a message indicating + process name, pid, pc, instruction, address, and the + fault code. + +1 The kernel will attempt to fix up the user process + performing the unaligned access. This is of course + slow (think about the floating point emulator) and + not recommended for production use. + +2 The kernel will send a SIGBUS signal to the user process + performing the unaligned access. +=== ======================================================== + +Note that not all combinations are supported - only values 0 through 5. +(6 and 7 don't make sense). + +For example, the following will turn on the warnings, but without +fixing up or sending SIGBUS signals:: + + echo 1 > /proc/cpu/alignment + +You can also read the content of the same file to get statistical +information on unaligned access occurrences plus the current mode of +operation for user space code. + + +Nicolas Pitre, Mar 13, 2001.

In addition to +modelling the hardware overlays, omapdss supports virtual overlays and overlay +managers. These can be used when updating a display with CPU or system DMA. + +omapdss driver support for audio +-------------------------------- +There exist several display technologies and standards that support audio as +well. Hence, it is relevant to update the DSS device driver to provide an audio +interface that may be used by an audio driver or any other driver interested in +the functionality. + +The audio_enable function is intended to prepare the relevant +IP for playback (e.g., enabling an audio FIFO, taking in/out of reset +some IP, enabling companion chips, etc). It is intended to be called before +audio_start. The audio_disable function performs the reverse operation and is +intended to be called after audio_stop. + +While a given DSS device driver may support audio, it is possible that for +certain configurations audio is not supported (e.g., an HDMI display using a +VESA video timing). The audio_supported function is intended to query whether +the current configuration of the display supports audio. + +The audio_config function is intended to configure all the relevant audio +parameters of the display. In order to make the function independent of any +specific DSS device driver, a struct omap_dss_audio is defined. Its purpose +is to contain all the required parameters for audio configuration. At the +moment, such structure contains pointers to IEC-60958 channel status word +and CEA-861 audio infoframe structures. This should be enough to support +HDMI and DisplayPort, as both are based on CEA-861 and IEC-60958. + +The audio_enable/disable, audio_config and audio_supported functions could be +implemented as functions that may sleep. Hence, they should not be called +while holding a spinlock or a readlock. + +The audio_start/audio_stop function is intended to effectively start/stop audio +playback after the configuration has taken place. These functions are designed +to be used in an atomic context. Hence, audio_start should return quickly and be +called only after all the needed resources for audio playback (audio FIFOs, +DMA channels, companion chips, etc) have been enabled to begin data transfers. +audio_stop is designed to only stop the audio transfers. The resources used +for playback are released using audio_disable. + +The enum omap_dss_audio_state may be used to help the implementations of +the interface to keep track of the audio state. The initial state is _DISABLED; +then, the state transitions to _CONFIGURED, and then, when it is ready to +play audio, to _ENABLED. The state _PLAYING is used when the audio is being +rendered. + + +Panel and controller drivers +---------------------------- + +The drivers implement panel or controller specific functionality and are not +usually visible to users except through omapfb driver. They register +themselves to the DSS driver. + +omapfb driver +------------- + +The omapfb driver implements arbitrary number of standard linux framebuffers. +These framebuffers can be routed flexibly to any overlays, thus allowing very +dynamic display architecture. + +The driver exports some omapfb specific ioctls, which are compatible with the +ioctls in the old driver. + +The rest of the non standard features are exported via sysfs. Whether the final +implementation will use sysfs, or ioctls, is still open. + +V4L2 drivers +------------ + +V4L2 is being implemented in TI. + +From omapdss point of view the V4L2 drivers should be similar to framebuffer +driver. + +Architecture +-------------------- + +Some clarification what the different components do: + + - Framebuffer is a memory area inside OMAP's SRAM/SDRAM that contains the + pixel data for the image. Framebuffer has width and height and color + depth. + - Overlay defines where the pixels are read from and where they go on the + screen. The overlay may be smaller than framebuffer, thus displaying only + part of the framebuffer. The position of the overlay may be changed if + the overlay is smaller than the display. + - Overlay manager combines the overlays in to one image and feeds them to + display. + - Display is the actual physical display device. + +A framebuffer can be connected to multiple overlays to show the same pixel data +on all of the overlays. Note that in this case the overlay input sizes must be +the same, but, in case of video overlays, the output size can be different. Any +framebuffer can be connected to any overlay. + +An overlay can be connected to one overlay manager.

To accomplish this, driver writers should use the +set_max_mpu_wakeup_lat() function to constrain the MPU wakeup +latency, and the set_max_dev_wakeup_lat() function to constrain the +device wakeup latency (from clk_enable() to accessibility). For +example:: + + /* Limit MPU wakeup latency */ + if (pdata->set_max_mpu_wakeup_lat) + (*pdata->set_max_mpu_wakeup_lat)(dev, tc); + + /* Limit device powerdomain wakeup latency */ + if (pdata->set_max_dev_wakeup_lat) + (*pdata->set_max_dev_wakeup_lat)(dev, td); + + /* total wakeup latency in this example: (tc + td) */ + +The PM parameters can be overwritten by calling the function again +with the new value. The settings can be removed by calling the +function with a t argument of -1 (except in the case of +set_max_bus_tput(), which should be called with an r argument of 0). + +The fifth function above, omap_pm_get_dev_context_loss_count(), +is intended as an optimization to allow drivers to determine whether the +device has lost its internal context.

GPIO controller on PXA3xx is now a dedicated controller, same as other + internal controllers like PWM, SSP and UART, with 128 internal signals + which can be routed to external through one or more MFPs (e.g. GPIO<0> + can be routed through either MFP_PIN_GPIO0 as well as MFP_PIN_GPIO0_2, + see arch/arm/mach-pxa/mfp-pxa300.h) + + 2.

There is currently no 'just turn on' setting + which may be required if this becomes a problem. + +4) s3c2410_gpio_setpin() can be replaced by gpio_set_value(), the old call + does not implicitly configure the relevant gpio to output. The gpio + direction should be changed before using gpio_set_value(). + +5) s3c2410_gpio_getpin() is replaceable by gpio_get_value() if the pin + has been set to input. It is currently unknown what the behaviour is + when using gpio_get_value() on an output pin (s3c2410_gpio_getpin + would return the value the pin is supposed to be outputting). + +6) s3c2410_gpio_getirq() should be directly replaceable with the + gpio_to_irq() call. + +The s3c2410_gpio and `gpio_` calls have always operated on the same gpio +numberspace, so there is no problem with converting the gpio numbering +between the calls. + + +Headers +------- + + See arch/arm/mach-s3c24xx/include/mach/regs-gpio.h for the list + of GPIO pins, and the configuration values for them.

These defines are used to tell + the GPIO functions which pin is to be used. + + With the conversion to gpiolib, there is no longer a direct conversion + from gpio pin number to register base address as in earlier kernels. This + is due to the number space required for newer SoCs where the later + GPIOs are not contiguous. + + +Configuring a pin +----------------- + + The following function allows the configuration of a given pin to + be changed. + + void s3c_gpio_cfgpin(unsigned int pin, unsigned int function); + + e.g.: + + s3c_gpio_cfgpin(S3C2410_GPA(0), S3C_GPIO_SFN(1)); + s3c_gpio_cfgpin(S3C2410_GPE(8), S3C_GPIO_SFN(2)); + + which would turn GPA(0) into the lowest Address line A0, and set + GPE(8) to be connected to the SDIO/MMC controller's SDDAT1 line. + + +Reading the current configuration +--------------------------------- + + The current configuration of a pin can be read by using standard + gpiolib function: + + s3c_gpio_getcfg(unsigned int pin); + + The return value will be from the same set of values which can be + passed to s3c_gpio_cfgpin(). + + +Configuring a pull-up resistor +------------------------------ + + A large proportion of the GPIO pins on the S3C2410 can have weak + pull-up resistors enabled.

The ones of most interest to the Linux + kernel are: + + == ====================== + WB Write-back (cacheable) + UC Uncacheable + WC Write-coalescing + == ====================== + + System memory typically uses the WB attribute. The UC attribute is + used for memory-mapped I/O devices. The WC attribute is uncacheable + like UC is, but writes may be delayed and combined to increase + performance for things like frame buffers. + + The Itanium architecture requires that we avoid accessing the same + page with both a cacheable mapping and an uncacheable mapping[1]. + + The design of the chipset determines which attributes are supported + on which regions of the address space. For example, some chipsets + support either WB or UC access to main memory, while others support + only WB access. + +Memory Map +========== + + Platform firmware describes the physical memory map and the + supported attributes for each region. At boot-time, the kernel uses + the EFI GetMemoryMap() interface. ACPI can also describe memory + devices and the attributes they support, but Linux/ia64 currently + doesn't use this information. + + The kernel uses the efi_memmap table returned from GetMemoryMap() to + learn the attributes supported by each region of physical address + space. Unfortunately, this table does not completely describe the + address space because some machines omit some or all of the MMIO + regions from the map. + + The kernel maintains another table, kern_memmap, which describes the + memory Linux is actually using and the attribute for each region. + This contains only system memory; it does not contain MMIO space. + + The kern_memmap table typically contains only a subset of the system + memory described by the efi_memmap. Linux/ia64 can't use all memory + in the system because of constraints imposed by the identity mapping + scheme. + + The efi_memmap table is preserved unmodified because the original + boot-time information is required for kexec. + +Kernel Identify Mappings +======================== + + Linux/ia64 identity mappings are done with large pages, currently + either 16MB or 64MB, referred to as "granules." Cacheable mappings + are speculative[2], so the processor can read any location in the + page at any time, independent of the programmer's intentions. This + means that to avoid attribute aliasing, Linux can create a cacheable + identity mapping only when the entire granule supports cacheable + access. + + Therefore, kern_memmap contains only full granule-sized regions that + can referenced safely by an identity mapping. + + Uncacheable mappings are not speculative, so the processor will + generate UC accesses only to locations explicitly referenced by + software. This allows UC identity mappings to cover granules that + are only partially populated, or populated with a combination of UC + and WB regions. + +User Mappings +============= + + User mappings are typically done with 16K or 64K pages. The smaller + page size allows more flexibility because only 16K or 64K has to be + homogeneous with respect to memory attributes. + +Potential Attribute Aliasing Cases +================================== + + There are several ways the kernel creates new mappings: + +mmap of /dev/mem +---------------- + + This uses remap_pfn_range(), which creates user mappings. These + mappings may be either WB or UC. If the region being mapped + happens to be in kern_memmap, meaning that it may also be mapped + by a kernel identity mapping, the user mapping must use the same + attribute as the kernel mapping. + + If the region is not in kern_memmap, the user mapping should use + an attribute reported as being supported in the EFI memory map. + + Since the EFI memory map does not describe MMIO on some + machines, this should use an uncacheable mapping as a fallback. + +mmap of /sys/class/pci_bus/.../legacy_mem +----------------------------------------- + + This is very similar to mmap of /dev/mem, except that legacy_mem + only allows mmap of the one megabyte "legacy MMIO" area for a + specific PCI bus. Typically this is the first megabyte of + physical address space, but it may be different on machines with + several VGA devices. + + "X" uses this to access VGA frame buffers. Using legacy_mem + rather than /dev/mem allows multiple instances of X to talk to + different VGA cards. + + The /dev/mem mmap constraints apply. + +mmap of /proc/bus/pci/.../??.? +------------------------------ + + This is an MMIO mmap of PCI functions, which additionally may or + may not be requested as using the WC attribute. + + If WC is requested, and the region in kern_memmap is either WC + or UC, and the EFI memory map designates the region as WC, then + the WC mapping is allowed. + + Otherwise, the user mapping must use the same attribute as the + kernel mapping. + +read/write of /dev/mem +---------------------- + + This uses copy_from_user(), which implicitly uses a kernel + identity mapping. This is obviously safe for things in + kern_memmap. + + There may be corner cases of things that are not in kern_memmap, + but could be accessed this way. For example, registers in MMIO + space are not in kern_memmap, but could be accessed with a UC + mapping. This would not cause attribute aliasing. But + registers typically can be accessed only with four-byte or + eight-byte accesses, and the copy_from_user() path doesn't allow + any control over the access size, so this would be dangerous. + +ioremap() +--------- + + This returns a mapping for use inside the kernel. + + If the region is in kern_memmap, we should use the attribute + specified there. + + If the EFI memory map reports that the entire granule supports + WB, we should use that (granules that are partially reserved + or occupied by firmware do not appear in kern_memmap). + + If the granule contains non-WB memory, but we can cover the + region safely with kernel page table mappings, we can use + ioremap_page_range() as most other architectures do. + + Failing all of the above, we have to fall back to a UC mapping. + +Past Problem Cases +================== + +mmap of various MMIO regions from /dev/mem by "X" on Intel platforms +-------------------------------------------------------------------- + + The EFI memory map may not report these MMIO regions. + + These must be allowed so that X will work. This means that + when the EFI memory map is incomplete, every /dev/mem mmap must + succeed. It may create either WB or UC user mappings, depending + on whether the region is in kern_memmap or the EFI memory map. + +mmap of 0x0-0x9FFFF /dev/mem by "hwinfo" on HP sx1000 with VGA enabled +---------------------------------------------------------------------- + + The EFI memory map reports the following attributes: + + =============== ======= ================== + 0x00000-0x9FFFF WB only + 0xA0000-0xBFFFF UC only (VGA frame buffer) + 0xC0000-0xFFFFF WB only + =============== ======= ================== + + This mmap is done with user pages, not kernel identity mappings, + so it is safe to use WB mappings. + + The kernel VGA driver may ioremap the VGA frame buffer at 0xA0000, + which uses a granule-sized UC mapping.

This +routine takes care of entering (full) kernel mode and calling the +normal Linux system call handler. For performance-critical system +calls, it is possible to write a hand-tuned fsyscall_handler. For +example, fsys.S contains fsys_getpid(), which is a hand-tuned version +of the getpid() system call. + +The entry and exit-state of an fsyscall handler is as follows: + +Machine state on entry to fsyscall handler +------------------------------------------ + + ========= =============================================================== + r10 0 + r11 saved ar.pfs (a user-level value) + r15 system call number + r16 "current" task pointer (in normal kernel-mode, this is in r13) + r32-r39 system call arguments + b6 return address (a user-level value) + ar.pfs previous frame-state (a user-level value) + PSR.be cleared to zero (i.e., little-endian byte order is in effect) + - all other registers may contain values passed in from user-mode + ========= =============================================================== + +Required machine state on exit to fsyscall handler +-------------------------------------------------- + + ========= =========================================================== + r11 saved ar.pfs (as passed into the fsyscall handler) + r15 system call number (as passed into the fsyscall handler) + r32-r39 system call arguments (as passed into the fsyscall handler) + b6 return address (as passed into the fsyscall handler) + ar.pfs previous frame-state (as passed into the fsyscall handler) + ========= =========================================================== + +Fsyscall handlers can execute with very little overhead, but with that +speed comes a set of restrictions: + + * Fsyscall-handlers MUST check for any pending work in the flags + member of the thread-info structure and if any of the + TIF_ALLWORK_MASK flags are set, the handler needs to fall back on + doing a full system call (by calling fsys_fallback_syscall). + + * Fsyscall-handlers MUST preserve incoming arguments (r32-r39, r11, + r15, b6, and ar.pfs) because they will be needed in case of a + system call restart. Of course, all "preserved" registers also + must be preserved, in accordance to the normal calling conventions. + + * Fsyscall-handlers MUST check argument registers for containing a + NaT value before using them in any way that could trigger a + NaT-consumption fault. If a system call argument is found to + contain a NaT value, an fsyscall-handler may return immediately + with r8=EINVAL, r10=-1. + + * Fsyscall-handlers MUST NOT use the "alloc" instruction or perform + any other operation that would trigger mandatory RSE + (register-stack engine) traffic. + + * Fsyscall-handlers MUST NOT write to any stacked registers because + it is not safe to assume that user-level called a handler with the + proper number of arguments. + + * Fsyscall-handlers need to be careful when accessing per-CPU variables: + unless proper safe-guards are taken (e.g., interruptions are avoided), + execution may be pre-empted and resumed on another CPU at any given + time. + + * Fsyscall-handlers must be careful not to leak sensitive kernel' + information back to user-level. In particular, before returning to + user-level, care needs to be taken to clear any scratch registers + that could contain sensitive information (note that the current + task pointer is not considered sensitive: it's already exposed + through ar.k6). + + * Fsyscall-handlers MUST NOT access user-memory without first + validating access-permission (this can be done typically via + probe.r.fault and/or probe.w.fault) and without guarding against + memory access exceptions (this can be done with the EX() macros + defined by asmmacro.h). + +The above restrictions may seem draconian, but remember that it's +possible to trade off some of the restrictions by paying a slightly +higher overhead. For example, if an fsyscall-handler could benefit +from the shadow register bank, it could temporarily disable PSR.i and +PSR.ic, switch to bank 0 (bsw.0) and then use the shadow registers as +needed. In other words, following the above rules yields extremely +fast system call execution (while fully preserving system call +semantics), but there is also a lot of flexibility in handling more +complicated cases. + +Signal handling +=============== + +The delivery of (asynchronous) signals must be delayed until fsys-mode +is exited. This is accomplished with the help of the lower-privilege +transfer trap: arch/ia64/kernel/process.c:do_notify_resume_user() +checks whether the interrupted task was in fsys-mode and, if so, sets +PSR.lp and returns immediately. When fsys-mode is exited via the +"br.ret" instruction that lowers the privilege level, a trap will +occur. The trap handler clears PSR.lp again and returns immediately. +The kernel exit path then checks for and delivers any pending signals. + +PSR Handling +============ + +The "epc" instruction doesn't change the contents of PSR at all. This +is in contrast to a regular interruption, which clears almost all +bits. Because of that, some care needs to be taken to ensure things +work as expected. The following discussion describes how each PSR bit +is handled. + +======= ======================================================================= +PSR.be Cleared when entering fsys-mode. A srlz.d instruction is used + to ensure the CPU is in little-endian mode before the first + load/store instruction is executed. PSR.be is normally NOT + restored upon return from an fsys-mode handler. In other + words, user-level code must not rely on PSR.be being preserved + across a system call. +PSR.up Unchanged. +PSR.ac Unchanged. +PSR.mfl Unchanged. Note: fsys-mode handlers must not write-registers! +PSR.mfh Unchanged. Note: fsys-mode handlers must not write-registers! +PSR.ic Unchanged.

Note: fsys-mode handlers must not write-registers! +PSR.sp Unchanged. +PSR.pp Unchanged. +PSR.di Unchanged. +PSR.si Unchanged. +PSR.db Unchanged. The kernel prevents user-level from setting a hardware + breakpoint that triggers at any privilege level other than + 3 (user-mode). +PSR.lp Unchanged. +PSR.tb Lazy redirect. If a taken-branch trap occurs while in + fsys-mode, the trap-handler modifies the saved machine state + such that execution resumes in the gate page at + syscall_via_break(), with privilege level 3. Note: the + taken branch would occur on the branch invoking the + fsyscall-handler, at which point, by definition, a syscall + restart is still safe. If the system call number is invalid, + the fsys-mode handler will return directly to user-level. This + return will trigger a taken-branch trap, but since the trap is + taken _after_ restoring the privilege level, the CPU has already + left fsys-mode, so no special treatment is needed. +PSR.rt Unchanged. +PSR.cpl Cleared to 0. +PSR.is Unchanged (guaranteed to be 0 on entry to the gate page). +PSR.mc Unchanged. +PSR.it Unchanged (guaranteed to be 1). +PSR.id Unchanged. Note: the ia64 linux kernel never sets this bit. +PSR.da Unchanged. Note: the ia64 linux kernel never sets this bit. +PSR.dd Unchanged.

Note: This bit could only have an effect if an fsys-mode + handler performed a speculative load that gets NaTted. If so, this + would be the normal & expected behavior, so no special treatment is + needed. +PSR.bn Unchanged.

If a system call argument is found to - contain a NaT value, an fsyscall-handler may return immediately - with r8=EINVAL, r10=-1. - - o Fsyscall-handlers MUST NOT use the "alloc" instruction or perform - any other operation that would trigger mandatory RSE - (register-stack engine) traffic. - - o Fsyscall-handlers MUST NOT write to any stacked registers because - it is not safe to assume that user-level called a handler with the - proper number of arguments. - - o Fsyscall-handlers need to be careful when accessing per-CPU variables: - unless proper safe-guards are taken (e.g., interruptions are avoided), - execution may be pre-empted and resumed on another CPU at any given - time. - - o Fsyscall-handlers must be careful not to leak sensitive kernel' - information back to user-level. In particular, before returning to - user-level, care needs to be taken to clear any scratch registers - that could contain sensitive information (note that the current - task pointer is not considered sensitive: it's already exposed - through ar.k6). - - o Fsyscall-handlers MUST NOT access user-memory without first - validating access-permission (this can be done typically via - probe.r.fault and/or probe.w.fault) and without guarding against - memory access exceptions (this can be done with the EX() macros - defined by asmmacro.h). - -The above restrictions may seem draconian, but remember that it's -possible to trade off some of the restrictions by paying a slightly -higher overhead. For example, if an fsyscall-handler could benefit -from the shadow register bank, it could temporarily disable PSR.i and -PSR.ic, switch to bank 0 (bsw.0) and then use the shadow registers as -needed. In other words, following the above rules yields extremely -fast system call execution (while fully preserving system call -semantics), but there is also a lot of flexibility in handling more -complicated cases. - -* Signal handling - -The delivery of (asynchronous) signals must be delayed until fsys-mode -is exited. This is accomplished with the help of the lower-privilege -transfer trap: arch/ia64/kernel/process.c:do_notify_resume_user() -checks whether the interrupted task was in fsys-mode and, if so, sets -PSR.lp and returns immediately. When fsys-mode is exited via the -"br.ret" instruction that lowers the privilege level, a trap will -occur. The trap handler clears PSR.lp again and returns immediately. -The kernel exit path then checks for and delivers any pending signals. - -* PSR Handling - -The "epc" instruction doesn't change the contents of PSR at all. This -is in contrast to a regular interruption, which clears almost all -bits. Because of that, some care needs to be taken to ensure things -work as expected. The following discussion describes how each PSR bit -is handled. - -PSR.be Cleared when entering fsys-mode. A srlz.d instruction is used - to ensure the CPU is in little-endian mode before the first - load/store instruction is executed. PSR.be is normally NOT - restored upon return from an fsys-mode handler. In other - words, user-level code must not rely on PSR.be being preserved - across a system call. -PSR.up Unchanged. -PSR.ac Unchanged. -PSR.mfl Unchanged. Note: fsys-mode handlers must not write-registers! -PSR.mfh Unchanged. Note: fsys-mode handlers must not write-registers! -PSR.ic Unchanged.

If a taken-branch trap occurs while in - fsys-mode, the trap-handler modifies the saved machine state - such that execution resumes in the gate page at - syscall_via_break(), with privilege level 3. Note: the - taken branch would occur on the branch invoking the - fsyscall-handler, at which point, by definition, a syscall - restart is still safe. If the system call number is invalid, - the fsys-mode handler will return directly to user-level. This - return will trigger a taken-branch trap, but since the trap is - taken _after_ restoring the privilege level, the CPU has already - left fsys-mode, so no special treatment is needed. -PSR.rt Unchanged. -PSR.cpl Cleared to 0. -PSR.is Unchanged (guaranteed to be 0 on entry to the gate page). -PSR.mc Unchanged. -PSR.it Unchanged (guaranteed to be 1). -PSR.id Unchanged.

That identifies and -verifies the original kernel stack, copies the dirty registers from -the MCA/INIT stack's RSE to the original stack's RSE, copies the -skeleton struct pt_regs and switch_stack to the original stack, fills -in the skeleton structures from the PAL minstate area and updates the -original stack's thread.ksp. That makes the original stack look -exactly like any other blocked task, i.e. it now appears to be -sleeping. To get a backtrace, just start with thread.ksp for the -original task and unwind like any other sleeping task. - ---- - -How do we identify the tasks that were running when MCA/INIT was -delivered? - -If the previous task has been verified and converted to a blocked -state, then sos->prev_task on the MCA/INIT stack is updated to point to -the previous task. You can look at that field in dumps or debuggers. -To help distinguish between the handler and the original tasks, -handlers have _TIF_MCA_INIT set in thread_info.flags. - -The sos data is always in the MCA/INIT handler stack, at offset -MCA_SOS_OFFSET. You can get that value from mca_asm.h or calculate it -as KERNEL_STACK_SIZE - sizeof(struct pt_regs) - sizeof(struct -ia64_sal_os_state), with 16 byte alignment for all structures. - -Also the comm field of the MCA/INIT task is modified to include the pid -of the original task, for humans to use. For example, a comm field of -'MCA 12159' means that pid 12159 was running when the MCA was -delivered. diff --git a/Documentation/ia64/serial.rst b/Documentation/ia64/serial.rst new file mode 100644 index 000000000000..1de70c305a79 --- /dev/null +++ b/Documentation/ia64/serial.rst @@ -0,0 +1,165 @@ +============== +Serial Devices +============== + +Serial Device Naming +==================== + + As of 2.6.10, serial devices on ia64 are named based on the + order of ACPI and PCI enumeration.

The system kernel's memory image is preserved across +the reboot and is accessible to the dump-capture kernel. + +You can use common commands, such as cp and scp, to copy the +memory image to a dump file on the local disk, or across the network to +a remote system. + +Kdump and kexec are currently supported on the x86, x86_64, ppc64, ia64, +s390x, arm and arm64 architectures. + +When the system kernel boots, it reserves a small section of memory for +the dump-capture kernel. This ensures that ongoing Direct Memory Access +(DMA) from the system kernel does not corrupt the dump-capture kernel. +The kexec -p command loads the dump-capture kernel into this reserved +memory. + +On x86 machines, the first 640 KB of physical memory is needed to boot, +regardless of where the kernel loads. Therefore, kexec backs up this +region just before rebooting into the dump-capture kernel. + +Similarly on PPC64 machines first 32KB of physical memory is needed for +booting regardless of where the kernel is loaded and to support 64K page +size kexec backs up the first 64KB memory. + +For s390x, when kdump is triggered, the crashkernel region is exchanged +with the region [0, crashkernel region size] and then the kdump kernel +runs in [0, crashkernel region size]. Therefore no relocatable kernel is +needed for s390x. + +All of the necessary information about the system kernel's core image is +encoded in the ELF format, and stored in a reserved area of memory +before a crash. The physical address of the start of the ELF header is +passed to the dump-capture kernel through the elfcorehdr= boot +parameter. Optionally the size of the ELF header can also be passed +when using the elfcorehdr=[size[KMG]@]offset[KMG] syntax. + + +With the dump-capture kernel, you can access the memory image through +/proc/vmcore. This exports the dump as an ELF-format file that you can +write out using file copy commands such as cp or scp. Further, you can +use analysis tools such as the GNU Debugger (GDB) and the Crash tool to +debug the dump file. This method ensures that the dump pages are correctly +ordered. + + +Setup and Installation +====================== + +Install kexec-tools +------------------- + +1) Login as the root user. + +2) Download the kexec-tools user-space package from the following URL: + +http://kernel.org/pub/linux/utils/kernel/kexec/kexec-tools.tar.gz + +This is a symlink to the latest version. + +The latest kexec-tools git tree is available at: + +- git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git +- http://www.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git + +There is also a gitweb interface available at +http://www.kernel.org/git/?p=utils/kernel/kexec/kexec-tools.git + +More information about kexec-tools can be found at +http://horms.net/projects/kexec/ + +3) Unpack the tarball with the tar command, as follows:: + + tar xvpzf kexec-tools.tar.gz + +4) Change to the kexec-tools directory, as follows:: + + cd kexec-tools-VERSION + +5) Configure the package, as follows:: + + ./configure + +6) Compile the package, as follows:: + + make + +7) Install the package, as follows:: + + make install + + +Build the system and dump-capture kernels +----------------------------------------- +There are two possible methods of using Kdump. + +1) Build a separate custom dump-capture kernel for capturing the + kernel core dump. + +2) Or use the system kernel binary itself as dump-capture kernel and there is + no need to build a separate dump-capture kernel. This is possible + only with the architectures which support a relocatable kernel. As + of today, i386, x86_64, ppc64, ia64, arm and arm64 architectures support + relocatable kernel. + +Building a relocatable kernel is advantageous from the point of view that +one does not have to build a second kernel for capturing the dump. But +at the same time one might want to build a custom dump capture kernel +suitable to his needs. + +Following are the configuration setting required for system and +dump-capture kernels for enabling kdump support. + +System kernel config options +---------------------------- + +1) Enable "kexec system call" in "Processor type and features.":: + + CONFIG_KEXEC=y + +2) Enable "sysfs file system support" in "Filesystem" -> "Pseudo + filesystems." This is usually enabled by default:: + + CONFIG_SYSFS=y + + Note that "sysfs file system support" might not appear in the "Pseudo + filesystems" menu if "Configure standard kernel features (for small + systems)" is not enabled in "General Setup." In this case, check the + .config file itself to ensure that sysfs is turned on, as follows:: + + grep 'CONFIG_SYSFS' .config + +3) Enable "Compile the kernel with debug info" in "Kernel hacking.":: + + CONFIG_DEBUG_INFO=Y + + This causes the kernel to be built with debug symbols. The dump + analysis tools require a vmlinux with debug symbols in order to read + and analyze a dump file. + +Dump-capture kernel config options (Arch Independent) +----------------------------------------------------- + +1) Enable "kernel crash dumps" support under "Processor type and + features":: + + CONFIG_CRASH_DUMP=y + +2) Enable "/proc/vmcore support" under "Filesystems" -> "Pseudo filesystems":: + + CONFIG_PROC_VMCORE=y + + (CONFIG_PROC_VMCORE is set by default when CONFIG_CRASH_DUMP is selected.) + +Dump-capture kernel config options (Arch Dependent, i386 and x86_64) +-------------------------------------------------------------------- + +1) On i386, enable high memory support under "Processor type and + features":: + + CONFIG_HIGHMEM64G=y + + or:: + + CONFIG_HIGHMEM4G + +2) On i386 and x86_64, disable symmetric multi-processing support + under "Processor type and features":: + + CONFIG_SMP=n + + (If CONFIG_SMP=y, then specify maxcpus=1 on the kernel command line + when loading the dump-capture kernel, see section "Load the Dump-capture + Kernel".) + +3) If one wants to build and use a relocatable kernel, + Enable "Build a relocatable kernel" support under "Processor type and + features":: + + CONFIG_RELOCATABLE=y + +4) Use a suitable value for "Physical address where the kernel is + loaded" (under "Processor type and features"). This only appears when + "kernel crash dumps" is enabled. A suitable value depends upon + whether kernel is relocatable or not. + + If you are using a relocatable kernel use CONFIG_PHYSICAL_START=0x100000 + This will compile the kernel for physical address 1MB, but given the fact + kernel is relocatable, it can be run from any physical address hence + kexec boot loader will load it in memory region reserved for dump-capture + kernel. + + Otherwise it should be the start of memory region reserved for + second kernel using boot parameter "crashkernel=Y@X". Here X is + start of memory region reserved for dump-capture kernel. + Generally X is 16MB (0x1000000). So you can set + CONFIG_PHYSICAL_START=0x1000000 + +5) Make and install the kernel and its modules.

This means that it is possible to use the system kernel + as a dump-capture kernel if desired. + + The crashkernel region can be automatically placed by the system + kernel at run time. This is done by specifying the base address as 0, + or omitting it all together:: + + crashkernel=256M@0 + + or:: + + crashkernel=256M + + If the start address is specified, note that the start address of the + kernel will be aligned to 64Mb, so if the start address is not then + any space below the alignment point will be wasted. + +Dump-capture kernel config options (Arch Dependent, arm) +---------------------------------------------------------- + +- To use a relocatable kernel, + Enable "AUTO_ZRELADDR" support under "Boot" options:: + + AUTO_ZRELADDR=y + +Dump-capture kernel config options (Arch Dependent, arm64) +---------------------------------------------------------- + +- Please note that kvm of the dump-capture kernel will not be enabled + on non-VHE systems even if it is configured. This is because the CPU + will not be reset to EL2 on panic. + +Extended crashkernel syntax +=========================== + +While the "crashkernel=size[@offset]" syntax is sufficient for most +configurations, sometimes it's handy to have the reserved memory dependent +on the value of System RAM -- that's mostly for distributors that pre-setup +the kernel command line to avoid a unbootable system after some memory has +been removed from the machine. + +The syntax is:: + + crashkernel=:[,:,...][@offset] + range=start-[end] + +For example:: + + crashkernel=512M-2G:64M,2G-:128M + +This would mean: + + 1) if the RAM is smaller than 512M, then don't reserve anything + (this is the "rescue" case) + 2) if the RAM size is between 512M and 2G (exclusive), then reserve 64M + 3) if the RAM size is larger than 2G, then reserve 128M + + + +Boot into System Kernel +======================= + +1) Update the boot loader (such as grub, yaboot, or lilo) configuration + files as necessary. + +2) Boot the system kernel with the boot parameter "crashkernel=Y@X", + where Y specifies how much memory to reserve for the dump-capture kernel + and X specifies the beginning of this reserved memory. For example, + "crashkernel=64M@16M" tells the system kernel to reserve 64 MB of memory + starting at physical address 0x01000000 (16MB) for the dump-capture kernel. + + On x86 and x86_64, use "crashkernel=64M@16M". + + On ppc64, use "crashkernel=128M@32M". + + On ia64, 256M@256M is a generous value that typically works. + The region may be automatically placed on ia64, see the + dump-capture kernel config option notes above. + If use sparse memory, the size should be rounded to GRANULE boundaries. + + On s390x, typically use "crashkernel=xxM". The value of xx is dependent + on the memory consumption of the kdump system. In general this is not + dependent on the memory size of the production system. + + On arm, the use of "crashkernel=Y@X" is no longer necessary; the + kernel will automatically locate the crash kernel image within the + first 512MB of RAM if X is not given. + + On arm64, use "crashkernel=Y[@X]". Note that the start address of + the kernel, X if explicitly specified, must be aligned to 2MiB (0x200000). + +Load the Dump-capture Kernel +============================ + +After booting to the system kernel, dump-capture kernel needs to be +loaded. + +Based on the architecture and type of image (relocatable or not), one +can choose to load the uncompressed vmlinux or compressed bzImage/vmlinuz +of dump-capture kernel. Following is the summary. + +For i386 and x86_64: + + - Use vmlinux if kernel is not relocatable. + - Use bzImage/vmlinuz if kernel is relocatable. + +For ppc64: + + - Use vmlinux + +For ia64: + + - Use vmlinux or vmlinuz.gz + +For s390x: + + - Use image or bzImage + +For arm: + + - Use zImage + +For arm64: + + - Use vmlinux or Image + +If you are using an uncompressed vmlinux image then use following command +to load dump-capture kernel:: + + kexec -p \ + --initrd= --args-linux \ + --append="root= " + +If you are using a compressed bzImage/vmlinuz, then use following command +to load dump-capture kernel:: + + kexec -p \ + --initrd= \ + --append="root= " + +If you are using a compressed zImage, then use following command +to load dump-capture kernel:: + + kexec --type zImage -p \ + --initrd= \ + --dtb= \ + --append="root= " + +If you are using an uncompressed Image, then use following command +to load dump-capture kernel:: + + kexec -p \ + --initrd= \ + --append="root= " + +Please note, that --args-linux does not need to be specified for ia64. +It is planned to make this a no-op on that architecture, but for now +it should be omitted + +Following are the arch specific command line options to be used while +loading dump-capture kernel. + +For i386, x86_64 and ia64: + + "1 irqpoll maxcpus=1 reset_devices" + +For ppc64: + + "1 maxcpus=1 noirqdistrib reset_devices" + +For s390x: + + "1 maxcpus=1 cgroup_disable=memory" + +For arm: + + "1 maxcpus=1 reset_devices" + +For arm64: + + "1 maxcpus=1 reset_devices" + +Notes on loading the dump-capture kernel: + +* By default, the ELF headers are stored in ELF64 format to support + systems with more than 4GB memory. On i386, kexec automatically checks if + the physical RAM size exceeds the 4 GB limit and if not, uses ELF32. + So, on non-PAE systems, ELF32 is always used. + + The --elf32-core-headers option can be used to force the generation of ELF32 + headers. This is necessary because GDB currently cannot open vmcore files + with ELF64 headers on 32-bit systems. + +* The "irqpoll" boot parameter reduces driver initialization failures + due to shared interrupts in the dump-capture kernel. + +* You must specify in the format corresponding to the root + device name in the output of mount command. + +* Boot parameter "1" boots the dump-capture kernel into single-user + mode without networking. If you want networking, use "3". + +* We generally don't have to bring up a SMP kernel just to capture the + dump. Hence generally it is useful either to build a UP dump-capture + kernel or specify maxcpus=1 option while loading dump-capture kernel. + Note, though maxcpus always works, you had better replace it with + nr_cpus to save memory if supported by the current ARCH, such as x86. + +* You should enable multi-cpu support in dump-capture kernel if you intend + to use multi-thread programs with it, such as parallel dump feature of + makedumpfile. Otherwise, the multi-thread program may have a great + performance degradation. To enable multi-cpu support, you should bring up an + SMP dump-capture kernel and specify maxcpus/nr_cpus, disable_cpu_apicid=[X] + options while loading it. + +* For s390x there are two kdump modes: If a ELF header is specified with + the elfcorehdr= kernel parameter, it is used by the kdump kernel as it + is done on all other architectures. If no elfcorehdr= kernel parameter is + specified, the s390x kdump kernel dynamically creates the header. The + second mode has the advantage that for CPU and memory hotplug, kdump has + not to be reloaded with kexec_load(). + +* For s390x systems with many attached devices the "cio_ignore" kernel + parameter should be used for the kdump kernel in order to prevent allocation + of kernel memory for devices that are not relevant for kdump. The same + applies to systems that use SCSI/FCP devices. In that case the + "allow_lun_scan" zfcp module parameter should be set to zero before + setting FCP devices online. + +Kernel Panic +============ + +After successfully loading the dump-capture kernel as previously +described, the system will reboot into the dump-capture kernel if a +system crash is triggered. Trigger points are located in panic(), +die(), die_nmi() and in the sysrq handler (ALT-SysRq-c). + +The following conditions will execute a crash trigger point: + +If a hard lockup is detected and "NMI watchdog" is configured, the system +will boot into the dump-capture kernel ( die_nmi() ). + +If die() is called, and it happens to be a thread with pid 0 or 1, or die() +is called inside interrupt context or die() is called and panic_on_oops is set, +the system will boot into the dump-capture kernel. + +On powerpc systems when a soft-reset is generated, die() is called by all cpus +and the system will boot into the dump-capture kernel. + +For testing purposes, you can trigger a crash by using "ALT-SysRq-c", +"echo c > /proc/sysrq-trigger" or write a module to force the panic. + +Write Out the Dump File +======================= + +After the dump-capture kernel is booted, write out the dump file with +the following command:: + + cp /proc/vmcore + + +Analysis +======== + +Before analyzing the dump image, you should reboot into a stable kernel. + +You can do limited analysis using GDB on the dump file copied out of +/proc/vmcore. Use the debug vmlinux built with -g and run the following +command:: + + gdb vmlinux + +Stack trace for the task on processor 0, register display, and memory +display work fine. + +Note: GDB cannot analyze core files generated in ELF64 format for x86. +On systems with a maximum of 4GB of memory, you can generate +ELF32-format headers using the --elf32-core-headers kernel option on the +dump kernel. + +You can also use the Crash utility to analyze dump files in Kdump +format. Crash is available on Dave Anderson's site at the following URL: + + http://people.redhat.com/~anderson/ + +Trigger Kdump on WARN() +======================= + +The kernel parameter, panic_on_warn, calls panic() in all WARN() paths. This +will cause a kdump to occur at the panic() call.

The system kernel's memory image is preserved across -the reboot and is accessible to the dump-capture kernel. - -You can use common commands, such as cp and scp, to copy the -memory image to a dump file on the local disk, or across the network to -a remote system. - -Kdump and kexec are currently supported on the x86, x86_64, ppc64, ia64, -s390x, arm and arm64 architectures. - -When the system kernel boots, it reserves a small section of memory for -the dump-capture kernel.

This is possible - only with the architectures which support a relocatable kernel. As - of today, i386, x86_64, ppc64, ia64, arm and arm64 architectures support - relocatable kernel. - -Building a relocatable kernel is advantageous from the point of view that -one does not have to build a second kernel for capturing the dump. But -at the same time one might want to build a custom dump capture kernel -suitable to his needs. - -Following are the configuration setting required for system and -dump-capture kernels for enabling kdump support. - -System kernel config options ----------------------------- - -1) Enable "kexec system call" in "Processor type and features.":: - - CONFIG_KEXEC=y - -2) Enable "sysfs file system support" in "Filesystem" -> "Pseudo - filesystems." This is usually enabled by default:: - - CONFIG_SYSFS=y - - Note that "sysfs file system support" might not appear in the "Pseudo - filesystems" menu if "Configure standard kernel features (for small - systems)" is not enabled in "General Setup." In this case, check the - .config file itself to ensure that sysfs is turned on, as follows:: - - grep 'CONFIG_SYSFS' .config - -3) Enable "Compile the kernel with debug info" in "Kernel hacking.":: - - CONFIG_DEBUG_INFO=Y - - This causes the kernel to be built with debug symbols. The dump - analysis tools require a vmlinux with debug symbols in order to read - and analyze a dump file. - -Dump-capture kernel config options (Arch Independent) ------------------------------------------------------ - -1) Enable "kernel crash dumps" support under "Processor type and - features":: - - CONFIG_CRASH_DUMP=y - -2) Enable "/proc/vmcore support" under "Filesystems" -> "Pseudo filesystems":: - - CONFIG_PROC_VMCORE=y - - (CONFIG_PROC_VMCORE is set by default when CONFIG_CRASH_DUMP is selected.) - -Dump-capture kernel config options (Arch Dependent, i386 and x86_64) --------------------------------------------------------------------- - -1) On i386, enable high memory support under "Processor type and - features":: - - CONFIG_HIGHMEM64G=y - - or:: - - CONFIG_HIGHMEM4G - -2) On i386 and x86_64, disable symmetric multi-processing support - under "Processor type and features":: - - CONFIG_SMP=n - - (If CONFIG_SMP=y, then specify maxcpus=1 on the kernel command line - when loading the dump-capture kernel, see section "Load the Dump-capture - Kernel".) - -3) If one wants to build and use a relocatable kernel, - Enable "Build a relocatable kernel" support under "Processor type and - features":: - - CONFIG_RELOCATABLE=y - -4) Use a suitable value for "Physical address where the kernel is - loaded" (under "Processor type and features"). This only appears when - "kernel crash dumps" is enabled. A suitable value depends upon - whether kernel is relocatable or not. - - If you are using a relocatable kernel use CONFIG_PHYSICAL_START=0x100000 - This will compile the kernel for physical address 1MB, but given the fact - kernel is relocatable, it can be run from any physical address hence - kexec boot loader will load it in memory region reserved for dump-capture - kernel. - - Otherwise it should be the start of memory region reserved for - second kernel using boot parameter "crashkernel=Y@X". Here X is - start of memory region reserved for dump-capture kernel. - Generally X is 16MB (0x1000000). So you can set - CONFIG_PHYSICAL_START=0x1000000 - -5) Make and install the kernel and its modules. DO NOT add this kernel - to the boot loader configuration files. - -Dump-capture kernel config options (Arch Dependent, ppc64) ----------------------------------------------------------- - -1) Enable "Build a kdump crash kernel" support under "Kernel" options:: - - CONFIG_CRASH_DUMP=y - -2) Enable "Build a relocatable kernel" support:: - - CONFIG_RELOCATABLE=y - - Make and install the kernel and its modules. - -Dump-capture kernel config options (Arch Dependent, ia64) ----------------------------------------------------------- - -- No specific options are required to create a dump-capture kernel - for ia64, other than those specified in the arch independent section - above. This means that it is possible to use the system kernel - as a dump-capture kernel if desired. - - The crashkernel region can be automatically placed by the system - kernel at run time. This is done by specifying the base address as 0, - or omitting it all together:: - - crashkernel=256M@0 - - or:: - - crashkernel=256M - - If the start address is specified, note that the start address of the - kernel will be aligned to 64Mb, so if the start address is not then - any space below the alignment point will be wasted. - -Dump-capture kernel config options (Arch Dependent, arm) ----------------------------------------------------------- - -- To use a relocatable kernel, - Enable "AUTO_ZRELADDR" support under "Boot" options:: - - AUTO_ZRELADDR=y - -Dump-capture kernel config options (Arch Dependent, arm64) ----------------------------------------------------------- - -- Please note that kvm of the dump-capture kernel will not be enabled - on non-VHE systems even if it is configured. This is because the CPU - will not be reset to EL2 on panic. - -Extended crashkernel syntax -=========================== - -While the "crashkernel=size[@offset]" syntax is sufficient for most -configurations, sometimes it's handy to have the reserved memory dependent -on the value of System RAM -- that's mostly for distributors that pre-setup -the kernel command line to avoid a unbootable system after some memory has -been removed from the machine. - -The syntax is:: - - crashkernel=:[,:,...][@offset] - range=start-[end] - -For example:: - - crashkernel=512M-2G:64M,2G-:128M - -This would mean: - - 1) if the RAM is smaller than 512M, then don't reserve anything - (this is the "rescue" case) - 2) if the RAM size is between 512M and 2G (exclusive), then reserve 64M - 3) if the RAM size is larger than 2G, then reserve 128M - - - -Boot into System Kernel -======================= - -1) Update the boot loader (such as grub, yaboot, or lilo) configuration - files as necessary. - -2) Boot the system kernel with the boot parameter "crashkernel=Y@X", - where Y specifies how much memory to reserve for the dump-capture kernel - and X specifies the beginning of this reserved memory. For example, - "crashkernel=64M@16M" tells the system kernel to reserve 64 MB of memory - starting at physical address 0x01000000 (16MB) for the dump-capture kernel. - - On x86 and x86_64, use "crashkernel=64M@16M". - - On ppc64, use "crashkernel=128M@32M". - - On ia64, 256M@256M is a generous value that typically works. - The region may be automatically placed on ia64, see the - dump-capture kernel config option notes above. - If use sparse memory, the size should be rounded to GRANULE boundaries. - - On s390x, typically use "crashkernel=xxM". The value of xx is dependent - on the memory consumption of the kdump system. In general this is not - dependent on the memory size of the production system. - - On arm, the use of "crashkernel=Y@X" is no longer necessary; the - kernel will automatically locate the crash kernel image within the - first 512MB of RAM if X is not given. - - On arm64, use "crashkernel=Y[@X]". Note that the start address of - the kernel, X if explicitly specified, must be aligned to 2MiB (0x200000). - -Load the Dump-capture Kernel -============================ - -After booting to the system kernel, dump-capture kernel needs to be -loaded. - -Based on the architecture and type of image (relocatable or not), one -can choose to load the uncompressed vmlinux or compressed bzImage/vmlinuz -of dump-capture kernel. Following is the summary. - -For i386 and x86_64: - - - Use vmlinux if kernel is not relocatable. - - Use bzImage/vmlinuz if kernel is relocatable. - -For ppc64: - - - Use vmlinux - -For ia64: - - - Use vmlinux or vmlinuz.gz - -For s390x: - - - Use image or bzImage - -For arm: - - - Use zImage - -For arm64: - - - Use vmlinux or Image - -If you are using an uncompressed vmlinux image then use following command -to load dump-capture kernel:: - - kexec -p \ - --initrd= --args-linux \ - --append="root= " - -If you are using a compressed bzImage/vmlinuz, then use following command -to load dump-capture kernel:: - - kexec -p \ - --initrd= \ - --append="root= " - -If you are using a compressed zImage, then use following command -to load dump-capture kernel:: - - kexec --type zImage -p \ - --initrd= \ - --dtb= \ - --append="root= " - -If you are using an uncompressed Image, then use following command -to load dump-capture kernel:: - - kexec -p \ - --initrd= \ - --append="root= " - -Please note, that --args-linux does not need to be specified for ia64. -It is planned to make this a no-op on that architecture, but for now -it should be omitted - -Following are the arch specific command line options to be used while -loading dump-capture kernel. - -For i386, x86_64 and ia64: - - "1 irqpoll maxcpus=1 reset_devices" - -For ppc64: - - "1 maxcpus=1 noirqdistrib reset_devices" - -For s390x: - - "1 maxcpus=1 cgroup_disable=memory" - -For arm: - - "1 maxcpus=1 reset_devices" - -For arm64: - - "1 maxcpus=1 reset_devices" - -Notes on loading the dump-capture kernel: - -* By default, the ELF headers are stored in ELF64 format to support - systems with more than 4GB memory. On i386, kexec automatically checks if - the physical RAM size exceeds the 4 GB limit and if not, uses ELF32. - So, on non-PAE systems, ELF32 is always used. - - The --elf32-core-headers option can be used to force the generation of ELF32 - headers. This is necessary because GDB currently cannot open vmcore files - with ELF64 headers on 32-bit systems. - -* The "irqpoll" boot parameter reduces driver initialization failures - due to shared interrupts in the dump-capture kernel. - -* You must specify in the format corresponding to the root - device name in the output of mount command. - -* Boot parameter "1" boots the dump-capture kernel into single-user - mode without networking. If you want networking, use "3". - -* We generally don't have to bring up a SMP kernel just to capture the - dump. Hence generally it is useful either to build a UP dump-capture - kernel or specify maxcpus=1 option while loading dump-capture kernel. - Note, though maxcpus always works, you had better replace it with - nr_cpus to save memory if supported by the current ARCH, such as x86. - -* You should enable multi-cpu support in dump-capture kernel if you intend - to use multi-thread programs with it, such as parallel dump feature of - makedumpfile. Otherwise, the multi-thread program may have a great - performance degradation. To enable multi-cpu support, you should bring up an - SMP dump-capture kernel and specify maxcpus/nr_cpus, disable_cpu_apicid=[X] - options while loading it. - -* For s390x there are two kdump modes: If a ELF header is specified with - the elfcorehdr= kernel parameter, it is used by the kdump kernel as it - is done on all other architectures. If no elfcorehdr= kernel parameter is - specified, the s390x kdump kernel dynamically creates the header. The - second mode has the advantage that for CPU and memory hotplug, kdump has - not to be reloaded with kexec_load(). - -* For s390x systems with many attached devices the "cio_ignore" kernel - parameter should be used for the kdump kernel in order to prevent allocation - of kernel memory for devices that are not relevant for kdump. The same - applies to systems that use SCSI/FCP devices. In that case the - "allow_lun_scan" zfcp module parameter should be set to zero before - setting FCP devices online. - -Kernel Panic -============ - -After successfully loading the dump-capture kernel as previously -described, the system will reboot into the dump-capture kernel if a -system crash is triggered. Trigger points are located in panic(), -die(), die_nmi() and in the sysrq handler (ALT-SysRq-c). - -The following conditions will execute a crash trigger point: - -If a hard lockup is detected and "NMI watchdog" is configured, the system -will boot into the dump-capture kernel ( die_nmi() ). - -If die() is called, and it happens to be a thread with pid 0 or 1, or die() -is called inside interrupt context or die() is called and panic_on_oops is set, -the system will boot into the dump-capture kernel. - -On powerpc systems when a soft-reset is generated, die() is called by all cpus -and the system will boot into the dump-capture kernel. - -For testing purposes, you can trigger a crash by using "ALT-SysRq-c", -"echo c > /proc/sysrq-trigger" or write a module to force the panic. - -Write Out the Dump File -======================= - -After the dump-capture kernel is booted, write out the dump file with -the following command:: - - cp /proc/vmcore - - -Analysis -======== - -Before analyzing the dump image, you should reboot into a stable kernel. - -You can do limited analysis using GDB on the dump file copied out of -/proc/vmcore. Use the debug vmlinux built with -g and run the following -command:: - - gdb vmlinux - -Stack trace for the task on processor 0, register display, and memory -display work fine. - -Note: GDB cannot analyze core files generated in ELF64 format for x86. -On systems with a maximum of 4GB of memory, you can generate -ELF32-format headers using the --elf32-core-headers kernel option on the -dump kernel. - -You can also use the Crash utility to analyze dump files in Kdump -format. Crash is available on Dave Anderson's site at the following URL: - - http://people.redhat.com/~anderson/ - -Trigger Kdump on WARN() -======================= - -The kernel parameter, panic_on_warn, calls panic() in all WARN() paths. This -will cause a kdump to occur at the panic() call.

The code that modifies the bzImage header, +along with the EFI-specific entry point that the firmware loader +jumps to are collectively known as the "EFI boot stub", and live in +arch/x86/boot/header.S and arch/x86/boot/compressed/eboot.c, +respectively. For ARM the EFI stub is implemented in +arch/arm/boot/compressed/efi-header.S and +arch/arm/boot/compressed/efi-stub.c. EFI stub code that is shared +between architectures is in drivers/firmware/efi/libstub. + +For arm64, there is no compressed kernel support, so the Image itself +masquerades as a PE/COFF image and the EFI stub is linked into the +kernel. The arm64 EFI stub lives in arch/arm64/kernel/efi-entry.S +and drivers/firmware/efi/libstub/arm64-stub.c. + +By using the EFI boot stub it's possible to boot a Linux kernel +without the use of a conventional EFI boot loader, such as grub or +elilo. Since the EFI boot stub performs the jobs of a boot loader, in +a certain sense it *IS* the boot loader. + +The EFI boot stub is enabled with the CONFIG_EFI_STUB kernel option. + + +How to install bzImage.efi +-------------------------- + +The bzImage located in arch/x86/boot/bzImage must be copied to the EFI +System Partition (ESP) and renamed with the extension ".efi". Without +the extension the EFI firmware loader will refuse to execute it. It's +not possible to execute bzImage.efi from the usual Linux file systems +because EFI firmware doesn't have support for them. For ARM the +arch/arm/boot/zImage should be copied to the system partition, and it +may not need to be renamed. Similarly for arm64, arch/arm64/boot/Image +should be copied but not necessarily renamed. + + +Passing kernel parameters from the EFI shell +-------------------------------------------- + +Arguments to the kernel can be passed after bzImage.efi, e.g.:: + + fs0:> bzImage.efi console=ttyS0 root=/dev/sda4 + + +The "initrd=" option +-------------------- + +Like most boot loaders, the EFI stub allows the user to specify +multiple initrd files using the "initrd=" option. This is the only EFI +stub-specific command line parameter, everything else is passed to the +kernel when it boots. + +The path to the initrd file must be an absolute path from the +beginning of the ESP, relative path names do not work. Also, the path +is an EFI-style path and directory elements must be separated with +backslashes (\). For example, given the following directory layout:: + + fs0:> + Kernels\ + bzImage.efi + initrd-large.img + + Ramdisks\ + initrd-small.img + initrd-medium.img + +to boot with the initrd-large.img file if the current working +directory is fs0:\Kernels, the following command must be used:: + + fs0:\Kernels> bzImage.efi initrd=\Kernels\initrd-large.img + +Notice how bzImage.efi can be specified with a relative path. That's +because the image we're executing is interpreted by the EFI shell, +which understands relative paths, whereas the rest of the command line +is passed to bzImage.efi. + + +The "dtb=" option +----------------- + +For the ARM and arm64 architectures, a device tree must be provided to +the kernel.

Throughout this document we'll assume that sysfs +is mounted on ``/sys``, although of course it may be mounted anywhere. +Both ``/proc/diskstats`` and sysfs use the same source for the information +and so should not differ. + +Here are examples of these different formats:: + + 2.4: + 3 0 39082680 hda 446216 784926 9550688 4382310 424847 312726 5922052 19310380 0 3376340 23705160 + 3 1 9221278 hda1 35486 0 35496 38030 0 0 0 0 0 38030 38030 + + 2.6+ sysfs: + 446216 784926 9550688 4382310 424847 312726 5922052 19310380 0 3376340 23705160 + 35486 38030 38030 38030 + + 2.6+ diskstats: + 3 0 hda 446216 784926 9550688 4382310 424847 312726 5922052 19310380 0 3376340 23705160 + 3 1 hda1 35486 38030 38030 38030 + + 4.18+ diskstats: + 3 0 hda 446216 784926 9550688 4382310 424847 312726 5922052 19310380 0 3376340 23705160 0 0 0 0 + +On 2.4 you might execute ``grep 'hda ' /proc/partitions``. On 2.6+, you have +a choice of ``cat /sys/block/hda/stat`` or ``grep 'hda ' /proc/diskstats``. + +The advantage of one over the other is that the sysfs choice works well +if you are watching a known, small set of disks. ``/proc/diskstats`` may +be a better choice if you are watching a large number of disks because +you'll avoid the overhead of 50, 100, or 500 or more opens/closes with +each snapshot of your disk statistics. + +In 2.4, the statistics fields are those after the device name. In +the above example, the first field of statistics would be 446216. +By contrast, in 2.6+ if you look at ``/sys/block/hda/stat``, you'll +find just the eleven fields, beginning with 446216. If you look at +``/proc/diskstats``, the eleven fields will be preceded by the major and +minor device numbers, and device name. Each of these formats provides +eleven fields of statistics, each meaning exactly the same things. +All fields except field 9 are cumulative since boot. Field 9 should +go to zero as I/Os complete; all others only increase (unless they +overflow and wrap). Yes, these are (32-bit or 64-bit) unsigned long +(native word size) numbers, and on a very busy or long-lived system they +may wrap. Applications should be prepared to deal with that; unless +your observations are measured in large numbers of minutes or hours, +they should not wrap twice before you notice them. + +Each set of stats only applies to the indicated device; if you want +system-wide stats you'll have to find all the devices and sum them all up. + +Field 1 -- # of reads completed + This is the total number of reads completed successfully. + +Field 2 -- # of reads merged, field 6 -- # of writes merged + Reads and writes which are adjacent to each other may be merged for + efficiency. Thus two 4K reads may become one 8K read before it is + ultimately handed to the disk, and so it will be counted (and queued) + as only one I/O. This field lets you know how often this was done. + +Field 3 -- # of sectors read + This is the total number of sectors read successfully. + +Field 4 -- # of milliseconds spent reading + This is the total number of milliseconds spent by all reads (as + measured from __make_request() to end_that_request_last()). + +Field 5 -- # of writes completed + This is the total number of writes completed successfully. + +Field 6 -- # of writes merged + See the description of field 2. + +Field 7 -- # of sectors written + This is the total number of sectors written successfully. + +Field 8 -- # of milliseconds spent writing + This is the total number of milliseconds spent by all writes (as + measured from __make_request() to end_that_request_last()). + +Field 9 -- # of I/Os currently in progress + The only field that should go to zero. Incremented as requests are + given to appropriate struct request_queue and decremented as they finish. + +Field 10 -- # of milliseconds spent doing I/Os + This field increases so long as field 9 is nonzero. + + Since 5.0 this field counts jiffies when at least one request was + started or completed. If request runs more than 2 jiffies then some + I/O time will not be accounted unless there are other requests. + +Field 11 -- weighted # of milliseconds spent doing I/Os + This field is incremented at each I/O start, I/O completion, I/O + merge, or read of these stats by the number of I/Os in progress + (field 9) times the number of milliseconds spent doing I/O since the + last update of this field. This can provide an easy measure of both + I/O completion time and the backlog that may be accumulating. + +Field 12 -- # of discards completed + This is the total number of discards completed successfully. + +Field 13 -- # of discards merged + See the description of field 2 + +Field 14 -- # of sectors discarded + This is the total number of sectors discarded successfully. + +Field 15 -- # of milliseconds spent discarding + This is the total number of milliseconds spent by all discards (as + measured from __make_request() to end_that_request_last()). + +To avoid introducing performance bottlenecks, no locks are held while +modifying these counters. This implies that minor inaccuracies may be +introduced when changes collide, so (for instance) adding up all the +read I/Os issued per partition should equal those made to the disks ... +but due to the lack of locking it may only be very close. + +In 2.6+, there are counters for each CPU, which make the lack of locking +almost a non-issue. When the statistics are read, the per-CPU counters +are summed (possibly overflowing the unsigned long variable they are +summed to) and the result given to the user. There is no convenient +user interface for accessing the per-CPU counters themselves. + +Disks vs Partitions +------------------- + +There were significant changes between 2.4 and 2.6+ in the I/O subsystem. +As a result, some statistic information disappeared. The translation from +a disk address relative to a partition to the disk address relative to +the host disk happens much earlier. All merges and timings now happen +at the disk level rather than at both the disk and partition level as +in 2.4. Consequently, you'll see a different statistics output on 2.6+ for +partitions from that for disks. There are only *four* fields available +for partitions on 2.6+ machines. This is reflected in the examples above. + +Field 1 -- # of reads issued + This is the total number of reads issued to this partition. + +Field 2 -- # of sectors read + This is the total number of sectors requested to be read from this + partition. + +Field 3 -- # of writes issued + This is the total number of writes issued to this partition. + +Field 4 -- # of sectors written + This is the total number of sectors requested to be written to + this partition. + +Note that since the address is translated to a disk-relative one, and no +record of the partition-relative address is kept, the subsequent success +or failure of the read cannot be attributed to the partition. In other +words, the number of reads for partitions is counted slightly before time +of queuing for partitions, and at completion for whole disks. This is +a subtle distinction that is probably uninteresting for most cases. + +More significant is the error induced by counting the numbers of +reads/writes before merges for partitions and after for disks. Since a +typical workload usually contains a lot of successive and adjacent requests, +the number of reads/writes issued can be several times higher than the +number of reads/writes completed. + +In 2.6.25, the full statistic set is again available for partitions and +disk and partition statistics are consistent again. Since we still don't +keep record of the partition-relative address, an operation is attributed to +the partition which contains the first sector of the request after the +eventual merges. As requests can be merged across partition, this could lead +to some (probably insignificant) inaccuracy. + +Additional notes +---------------- + +In 2.6+, sysfs is not mounted by default. If your distribution of +Linux hasn't added it already, here's the line you'll want to add to +your ``/etc/fstab``:: + + none /sys sysfs defaults 0 0 + + +In 2.6+, all disk statistics were removed from ``/proc/stat``. In 2.4, they +appear in both ``/proc/partitions`` and ``/proc/stat``, although the ones in +``/proc/stat`` take a very different format from those in ``/proc/partitions`` +(see proc(5), if your system has it.) + +-- ricklind@us.ibm.com diff --git a/Documentation/admin-guide/kernel-parameters.txt b/Documentation/admin-guide/kernel-parameters.txt index a571a67e0c85..19b1e3bef56c 100644 --- a/Documentation/admin-guide/kernel-parameters.txt +++ b/Documentation/admin-guide/kernel-parameters.txt @@ -5066,7 +5066,7 @@ vga= [BOOT,X86-32] Select a particular video mode See Documentation/x86/boot.rst and - Documentation/svga.txt. + Documentation/admin-guide/svga.rst.

Avoid sending scheduler IPIs to the CPU to be de-jittered, + for example, ensure that at most one runnable kthread is present + on that CPU. If a thread that expects to run on the de-jittered + CPU awakens, the scheduler will send an IPI that can result in + a subsequent SCHED_SOFTIRQ. +2.

Offload callbacks and keep the CPU in either dyntick-idle or + adaptive-ticks state by doing all of the following: + + a. CONFIG_NO_HZ_FULL=y and ensure that the CPU to be + de-jittered is marked as an adaptive-ticks CPU using the + "nohz_full=" boot parameter. Bind the rcuo kthreads to + housekeeping CPUs, which can tolerate OS jitter. + b.

Enable RCU to do its processing remotely via dyntick-idle by + doing all of the following: + + a. Build with CONFIG_NO_HZ=y and CONFIG_RCU_FAST_NO_HZ=y. + b. Ensure that the CPU goes idle frequently, allowing other + CPUs to detect that it has passed through an RCU quiescent + state. If the kernel is built with CONFIG_NO_HZ_FULL=y, + userspace execution also allows other CPUs to detect that + the CPU in question has passed through a quiescent state. + c.

Run your workload at a real-time priority, which will allow + preempting the kworker daemons. +2. A given workqueue can be made visible in the sysfs filesystem + by passing the WQ_SYSFS to that workqueue's alloc_workqueue(). + Such a workqueue can be confined to a given subset of the + CPUs using the ``/sys/devices/virtual/workqueue/*/cpumask`` sysfs + files. The set of WQ_SYSFS workqueues can be displayed using + "ls sys/devices/virtual/workqueue". That said, the workqueues + maintainer would like to caution people against indiscriminately + sprinkling WQ_SYSFS across all the workqueues. The reason for + caution is that it is easy to add WQ_SYSFS, but because sysfs is + part of the formal user/kernel API, it can be nearly impossible + to remove it, even if its addition was a mistake. +3. Do any of the following needed to avoid jitter that your + application cannot tolerate: + + a. Build your kernel with CONFIG_SLUB=y rather than + CONFIG_SLAB=y, thus avoiding the slab allocator's periodic + use of each CPU's workqueues to run its cache_reap() + function. + b. Avoid using oprofile, thus avoiding OS jitter from + wq_sync_buffer(). + c. Limit your CPU frequency so that a CPU-frequency + governor is not required, possibly enlisting the aid of + special heatsinks or other cooling technologies. If done + correctly, and if you CPU architecture permits, you should + be able to build your kernel with CONFIG_CPU_FREQ=n to + avoid the CPU-frequency governor periodically running + on each CPU, including cs_dbs_timer() and od_dbs_timer(). + + WARNING: Please check your CPU specifications to + make sure that this is safe on your particular system. + d. As of v3.18, Christoph Lameter's on-demand vmstat workers + commit prevents OS jitter due to vmstat_update() on + CONFIG_SMP=y systems. Before v3.18, is not possible + to entirely get rid of the OS jitter, but you can + decrease its frequency by writing a large value to + /proc/sys/vm/stat_interval. The default value is HZ, + for an interval of one second. Of course, larger values + will make your virtual-memory statistics update more + slowly. Of course, you can also run your workload at + a real-time priority, thus preempting vmstat_update(), + but if your workload is CPU-bound, this is a bad idea. + However, there is an RFC patch from Christoph Lameter + (based on an earlier one from Gilad Ben-Yossef) that + reduces or even eliminates vmstat overhead for some + workloads at https://lkml.org/lkml/2013/9/4/379. + e. Boot with "elevator=noop" to avoid workqueue use by + the block layer. + f. If running on high-end powerpc servers, build with + CONFIG_PPC_RTAS_DAEMON=n. This prevents the RTAS + daemon from running on each CPU every second or so. + (This will require editing Kconfig files and will defeat + this platform's RAS functionality.) This avoids jitter + due to the rtas_event_scan() function. + WARNING: Please check your CPU specifications to + make sure that this is safe on your particular system. + g. If running on Cell Processor, build your kernel with + CBE_CPUFREQ_SPU_GOVERNOR=n to avoid OS jitter from + spu_gov_work(). + WARNING: Please check your CPU specifications to + make sure that this is safe on your particular system. + h. If running on PowerMAC, build your kernel with + CONFIG_PMAC_RACKMETER=n to disable the CPU-meter, + avoiding OS jitter from rackmeter_do_timer(). + +Name: + rcuc/%u + +Purpose: + Execute RCU callbacks in CONFIG_RCU_BOOST=y kernels. + +To reduce its OS jitter, do at least one of the following: + +1. Build the kernel with CONFIG_PREEMPT=n. This prevents these + kthreads from being created in the first place, and also obviates + the need for RCU priority boosting. This approach is feasible + for workloads that do not require high degrees of responsiveness. +2. Build the kernel with CONFIG_RCU_BOOST=n. This prevents these + kthreads from being created in the first place. This approach + is feasible only if your workload never requires RCU priority + boosting, for example, if you ensure frequent idle time on all + CPUs that might execute within the kernel. +3. Build with CONFIG_RCU_NOCB_CPU=y and boot with the rcu_nocbs= + boot parameter offloading RCU callbacks from all CPUs susceptible + to OS jitter. This approach prevents the rcuc/%u kthreads from + having any work to do, so that they are never awakened. +4. Ensure that the CPU never enters the kernel, and, in particular, + avoid initiating any CPU hotplug operations on this CPU. This is + another way of preventing any callbacks from being queued on the + CPU, again preventing the rcuc/%u kthreads from having any work + to do. + +Name: + rcuop/%d and rcuos/%d + +Purpose: + Offload RCU callbacks from the corresponding CPU. + +To reduce its OS jitter, do at least one of the following: + +1.

Build with CONFIG_RCU_NOCB_CPU=n, which will prevent these + kthreads from being created in the first place. However, please + note that this will not eliminate OS jitter, but will instead + shift it to RCU_SOFTIRQ. + +Name: + watchdog/%u + +Purpose: + Detect software lockups on each CPU. + +To reduce its OS jitter, do at least one of the following: + +1. Build with CONFIG_LOCKUP_DETECTOR=n, which will prevent these + kthreads from being created in the first place. +2. Boot with "nosoftlockup=0", which will also prevent these kthreads + from being created. Other related watchdog and softlockup boot + parameters may be found in Documentation/admin-guide/kernel-parameters.rst + and Documentation/watchdog/watchdog-parameters.rst. +3. Echo a zero to /proc/sys/kernel/watchdog to disable the + watchdog timer. +4.

It is a complete +replacement for the MSDOS style partitions. It stores its information in a +1MiB journalled database at the end of the physical disk. The size of +partitions is limited only by disk space. The maximum number of partitions is +nearly 2000. + +Any partitions created under the LDM are called "Dynamic Disks". There are no +longer any primary or extended partitions. Normal MSDOS style partitions are +now known as Basic Disks. + +If you wish to use Spanned, Striped, Mirrored or RAID 5 Volumes, you must use +Dynamic Disks.

A direct consequence of this is that, +in principle, they should work in any architecture where these +subsystems are present. + +A periodic hrtimer runs to generate interrupts and kick the watchdog +task. An NMI perf event is generated every "watchdog_thresh" +(compile-time initialized to 10 and configurable through sysctl of the +same name) seconds to check for hardlockups. If any CPU in the system +does not receive any hrtimer interrupt during that time the +'hardlockup detector' (the handler for the NMI perf event) will +generate a kernel warning or call panic, depending on the +configuration. + +The watchdog task is a high priority kernel thread that updates a +timestamp every time it is scheduled. If that timestamp is not updated +for 2*watchdog_thresh seconds (the softlockup threshold) the +'softlockup detector' (coded inside the hrtimer callback function) +will dump useful debug information to the system log, after which it +will call panic if it was instructed to do so or resume execution of +other kernel code. + +The period of the hrtimer is 2*watchdog_thresh/5, which means it has +two or three chances to generate an interrupt before the hardlockup +detector kicks in. + +As explained above, a kernel knob is provided that allows +administrators to configure the period of the hrtimer and the perf +event. The right value for a particular environment is a trade-off +between fast response to lockups and detection overhead. + +By default, the watchdog runs on all online cores. However, on a +kernel configured with NO_HZ_FULL, by default the watchdog runs only +on the housekeeping cores, not the cores specified in the "nohz_full" +boot argument. If we allowed the watchdog to run by default on +the "nohz_full" cores, we would have to run timer ticks to activate +the scheduler, which would prevent the "nohz_full" functionality +from protecting the user code on those cores from the kernel. +Of course, disabling it by default on the nohz_full cores means that +when those cores do enter the kernel, by default we will not be +able to detect if they lock up. However, allowing the watchdog +to continue to run on the housekeeping (non-tickless) cores means +that we will continue to detect lockups properly on those cores. + +In either case, the set of cores excluded from running the watchdog +may be adjusted via the kernel.watchdog_cpumask sysctl.

Such clocks will normally not track +the local time zone or daylight savings time -- unless they dual boot +with MS-Windows -- but will instead be set to Coordinated Universal Time +(UTC, formerly "Greenwich Mean Time"). + +The newest non-PC hardware tends to just count seconds, like the time(2) +system call reports, but RTCs also very commonly represent time using +the Gregorian calendar and 24 hour time, as reported by gmtime(3). + +Linux has two largely-compatible userspace RTC API families you may +need to know about: + + * /dev/rtc ... is the RTC provided by PC compatible systems, + so it's not very portable to non-x86 systems. + + * /dev/rtc0, /dev/rtc1 ... are part of a framework that's + supported by a wide variety of RTC chips on all systems. + +Programmers need to understand that the PC/AT functionality is not +always available, and some systems can do much more. That is, the +RTCs use the same API to make requests in both RTC frameworks (using +different filenames of course), but the hardware may not offer the +same functionality. For example, not every RTC is hooked up to an +IRQ, so they can't all issue alarms; and where standard PC RTCs can +only issue an alarm up to 24 hours in the future, other hardware may +be able to schedule one any time in the upcoming century. + + +Old PC/AT-Compatible driver: /dev/rtc +-------------------------------------- + +All PCs (even Alpha machines) have a Real Time Clock built into them. +Usually they are built into the chipset of the computer, but some may +actually have a Motorola MC146818 (or clone) on the board. This is the +clock that keeps the date and time while your computer is turned off. + +ACPI has standardized that MC146818 functionality, and extended it in +a few ways (enabling longer alarm periods, and wake-from-hibernate). +That functionality is NOT exposed in the old driver. + +However it can also be used to generate signals from a slow 2Hz to a +relatively fast 8192Hz, in increments of powers of two. These signals +are reported by interrupt number 8. (Oh! So *that* is what IRQ 8 is +for...) It can also function as a 24hr alarm, raising IRQ 8 when the +alarm goes off. The alarm can also be programmed to only check any +subset of the three programmable values, meaning that it could be set to +ring on the 30th second of the 30th minute of every hour, for example. +The clock can also be set to generate an interrupt upon every clock +update, thus generating a 1Hz signal. + +The interrupts are reported via /dev/rtc (major 10, minor 135, read only +character device) in the form of an unsigned long. The low byte contains +the type of interrupt (update-done, alarm-rang, or periodic) that was +raised, and the remaining bytes contain the number of interrupts since +the last read. Status information is reported through the pseudo-file +/proc/driver/rtc if the /proc filesystem was enabled. The driver has +built in locking so that only one process is allowed to have the /dev/rtc +interface open at a time. + +A user process can monitor these interrupts by doing a read(2) or a +select(2) on /dev/rtc -- either will block/stop the user process until +the next interrupt is received. This is useful for things like +reasonably high frequency data acquisition where one doesn't want to +burn up 100% CPU by polling gettimeofday etc. etc. + +At high frequencies, or under high loads, the user process should check +the number of interrupts received since the last read to determine if +there has been any interrupt "pileup" so to speak. Just for reference, a +typical 486-33 running a tight read loop on /dev/rtc will start to suffer +occasional interrupt pileup (i.e. > 1 IRQ event since last read) for +frequencies above 1024Hz. So you really should check the high bytes +of the value you read, especially at frequencies above that of the +normal timer interrupt, which is 100Hz. + +Programming and/or enabling interrupt frequencies greater than 64Hz is +only allowed by root. This is perhaps a bit conservative, but we don't want +an evil user generating lots of IRQs on a slow 386sx-16, where it might have +a negative impact on performance. This 64Hz limit can be changed by writing +a different value to /proc/sys/dev/rtc/max-user-freq. Note that the +interrupt handler is only a few lines of code to minimize any possibility +of this effect. + +Also, if the kernel time is synchronized with an external source, the +kernel will write the time back to the CMOS clock every 11 minutes. In +the process of doing this, the kernel briefly turns off RTC periodic +interrupts, so be aware of this if you are doing serious work. If you +don't synchronize the kernel time with an external source (via ntp or +whatever) then the kernel will keep its hands off the RTC, allowing you +exclusive access to the device for your applications. + +The alarm and/or interrupt frequency are programmed into the RTC via +various ioctl(2) calls as listed in ./include/linux/rtc.h +Rather than write 50 pages describing the ioctl() and so on, it is +perhaps more useful to include a small test program that demonstrates +how to use them, and demonstrates the features of the driver. This is +probably a lot more useful to people interested in writing applications +that will be using this driver. See the code at the end of this document. + +(The original /dev/rtc driver was written by Paul Gortmaker.) + + +New portable "RTC Class" drivers: /dev/rtcN +-------------------------------------------- + +Because Linux supports many non-ACPI and non-PC platforms, some of which +have more than one RTC style clock, it needed a more portable solution +than expecting a single battery-backed MC146818 clone on every system. +Accordingly, a new "RTC Class" framework has been defined. It offers +three different userspace interfaces: + + * /dev/rtcN ... much the same as the older /dev/rtc interface + + * /sys/class/rtc/rtcN ... sysfs attributes support readonly + access to some RTC attributes. + + * /proc/driver/rtc ... the system clock RTC may expose itself + using a procfs interface. If there is no RTC for the system clock, + rtc0 is used by default. More information is (currently) shown + here than through sysfs. + +The RTC Class framework supports a wide variety of RTCs, ranging from those +integrated into embeddable system-on-chip (SOC) processors to discrete chips +using I2C, SPI, or some other bus to communicate with the host CPU. There's +even support for PC-style RTCs ... including the features exposed on newer PCs +through ACPI. + +The new framework also removes the "one RTC per system" restriction. For +example, maybe the low-power battery-backed RTC is a discrete I2C chip, but +a high functionality RTC is integrated into the SOC. That system might read +the system clock from the discrete RTC, but use the integrated one for all +other tasks, because of its greater functionality. + +Check out tools/testing/selftests/rtc/rtctest.c for an example usage of the +ioctl interface. diff --git a/Documentation/admin-guide/svga.rst b/Documentation/admin-guide/svga.rst new file mode 100644 index 000000000000..b6c2f9acca92 --- /dev/null +++ b/Documentation/admin-guide/svga.rst @@ -0,0 +1,249 @@ +.. include:: + +================================= +Video Mode Selection Support 2.13 +================================= + +:Copyright: |copy| 1995--1999 Martin Mares, + +Intro +~~~~~ + +This small document describes the "Video Mode Selection" feature which +allows the use of various special video modes supported by the video BIOS.

In +case your chipset has been detected, some chipset-specific modes are shown as +well (some of these might be missing or unusable on your machine as different +BIOSes are often shipped with the same card and the mode numbers depend purely +on the VGA BIOS). + +The modes displayed on the menu are partially sorted: The list starts with +the standard modes (80x25 and 80x50) followed by "special" modes (80x28 and +80x43), local modes (if the local modes feature is enabled), VESA modes and +finally SVGA modes for the auto-detected adapter. + +If you are not happy with the mode list offered (e.g., if you think your card +is able to do more), you can enter "scan" instead of item number / mode ID. The +program will try to ask the BIOS for all possible video mode numbers and test +what happens then. The screen will be probably flashing wildly for some time and +strange noises will be heard from inside the monitor and so on and then, really +all consistent video modes supported by your BIOS will appear (plus maybe some +``ghost modes``). If you are afraid this could damage your monitor, don't use +this function. + +After scanning, the mode ordering is a bit different: the auto-detected SVGA +modes are not listed at all and the modes revealed by ``scan`` are shown before +all VESA modes. + +Mode IDs +~~~~~~~~ + +Because of the complexity of all the video stuff, the video mode IDs +used here are also a bit complex. A video mode ID is a 16-bit number usually +expressed in a hexadecimal notation (starting with "0x"). You can set a mode +by entering its mode directly if you know it even if it isn't shown on the menu. + +The ID numbers can be divided to those regions:: + + 0x0000 to 0x00ff - menu item references. 0x0000 is the first item. Don't use + outside the menu as this can change from boot to boot (especially if you + have used the ``scan`` feature). + + 0x0100 to 0x017f - standard BIOS modes. The ID is a BIOS video mode number + (as presented to INT 10, function 00) increased by 0x0100. + + 0x0200 to 0x08ff - VESA BIOS modes. The ID is a VESA mode ID increased by + 0x0100. All VESA modes should be autodetected and shown on the menu. + + 0x0900 to 0x09ff - Video7 special modes. Set by calling INT 0x10, AX=0x6f05. + (Usually 940=80x43, 941=132x25, 942=132x44, 943=80x60, 944=100x60, + 945=132x28 for the standard Video7 BIOS) + + 0x0f00 to 0x0fff - special modes (they are set by various tricks -- usually + by modifying one of the standard modes). Currently available: + 0x0f00 standard 80x25, don't reset mode if already set (=FFFF) + 0x0f01 standard with 8-point font: 80x43 on EGA, 80x50 on VGA + 0x0f02 VGA 80x43 (VGA switched to 350 scanlines with a 8-point font) + 0x0f03 VGA 80x28 (standard VGA scans, but 14-point font) + 0x0f04 leave current video mode + 0x0f05 VGA 80x30 (480 scans, 16-point font) + 0x0f06 VGA 80x34 (480 scans, 14-point font) + 0x0f07 VGA 80x60 (480 scans, 8-point font) + 0x0f08 Graphics hack (see the VIDEO_GFX_HACK paragraph below) + + 0x1000 to 0x7fff - modes specified by resolution. The code has a "0xRRCC" + form where RR is a number of rows and CC is a number of columns. + E.g., 0x1950 corresponds to a 80x25 mode, 0x2b84 to 132x43 etc. + This is the only fully portable way to refer to a non-standard mode, + but it relies on the mode being found and displayed on the menu + (remember that mode scanning is not done automatically). + + 0xff00 to 0xffff - aliases for backward compatibility: + 0xffff equivalent to 0x0f00 (standard 80x25) + 0xfffe equivalent to 0x0f01 (EGA 80x43 or VGA 80x50) + +If you add 0x8000 to the mode ID, the program will try to recalculate +vertical display timing according to mode parameters, which can be used to +eliminate some annoying bugs of certain VGA BIOSes (usually those used for +cards with S3 chipsets and old Cirrus Logic BIOSes) -- mainly extra lines at the +end of the display. + +Options +~~~~~~~ + +Build options for arch/x86/boot/* are selected by the kernel kconfig +utility and the kernel .config file. + +VIDEO_GFX_HACK - includes special hack for setting of graphics modes +to be used later by special drivers. +Allows to set _any_ BIOS mode including graphic ones and forcing specific +text screen resolution instead of peeking it from BIOS variables. Don't use +unless you think you know what you're doing. To activate this setup, use +mode number 0x0f08 (see the Mode IDs section above). + +Still doesn't work? +~~~~~~~~~~~~~~~~~~~ + +When the mode detection doesn't work (e.g., the mode list is incorrect or +the machine hangs instead of displaying the menu), try to switch off some of +the configuration options listed under "Options". If it fails, you can still use +your kernel with the video mode set directly via the kernel parameter. + +In either case, please send me a bug report containing what _exactly_ +happens and how do the configuration switches affect the behaviour of the bug. + +If you start Linux from M$-DOS, you might also use some DOS tools for +video mode setting. In this case, you must specify the 0x0f04 mode ("leave +current settings") to Linux, because if you don't and you use any non-standard +mode, Linux will switch to 80x25 automatically. + +If you set some extended mode and there's one or more extra lines on the +bottom of the display containing already scrolled-out text, your VGA BIOS +contains the most common video BIOS bug called "incorrect vertical display +end setting". Adding 0x8000 to the mode ID might fix the problem. Unfortunately, +this must be done manually -- no autodetection mechanisms are available. + +History +~~~~~~~ + +=============== ================================================================ +1.0 (??-Nov-95) First version supporting all adapters supported by the old + setup.S + Cirrus Logic 54XX.

In other -words, the number of reads for partitions is counted slightly before time -of queuing for partitions, and at completion for whole disks. This is -a subtle distinction that is probably uninteresting for most cases. - -More significant is the error induced by counting the numbers of -reads/writes before merges for partitions and after for disks. Since a -typical workload usually contains a lot of successive and adjacent requests, -the number of reads/writes issued can be several times higher than the -number of reads/writes completed. - -In 2.6.25, the full statistic set is again available for partitions and -disk and partition statistics are consistent again. Since we still don't -keep record of the partition-relative address, an operation is attributed to -the partition which contains the first sector of the request after the -eventual merges.

The low byte contains -the type of interrupt (update-done, alarm-rang, or periodic) that was -raised, and the remaining bytes contain the number of interrupts since -the last read.

If you -don't synchronize the kernel time with an external source (via ntp or -whatever) then the kernel will keep its hands off the RTC, allowing you -exclusive access to the device for your applications. - -The alarm and/or interrupt frequency are programmed into the RTC via -various ioctl(2) calls as listed in ./include/linux/rtc.h -Rather than write 50 pages describing the ioctl() and so on, it is -perhaps more useful to include a small test program that demonstrates -how to use them, and demonstrates the features of the driver. This is -probably a lot more useful to people interested in writing applications -that will be using this driver. See the code at the end of this document. - -(The original /dev/rtc driver was written by Paul Gortmaker.) - - -New portable "RTC Class" drivers: /dev/rtcN --------------------------------------------- - -Because Linux supports many non-ACPI and non-PC platforms, some of which -have more than one RTC style clock, it needed a more portable solution -than expecting a single battery-backed MC146818 clone on every system. -Accordingly, a new "RTC Class" framework has been defined. It offers -three different userspace interfaces: - - * /dev/rtcN ... much the same as the older /dev/rtc interface - - * /sys/class/rtc/rtcN ... sysfs attributes support readonly - access to some RTC attributes. - - * /proc/driver/rtc ... the system clock RTC may expose itself - using a procfs interface. If there is no RTC for the system clock, - rtc0 is used by default. More information is (currently) shown - here than through sysfs. - -The RTC Class framework supports a wide variety of RTCs, ranging from those -integrated into embeddable system-on-chip (SOC) processors to discrete chips -using I2C, SPI, or some other bus to communicate with the host CPU. There's -even support for PC-style RTCs ... including the features exposed on newer PCs -through ACPI. - -The new framework also removes the "one RTC per system" restriction. For -example, maybe the low-power battery-backed RTC is a discrete I2C chip, but -a high functionality RTC is integrated into the SOC. That system might read -the system clock from the discrete RTC, but use the integrated one for all -other tasks, because of its greater functionality. - -Check out tools/testing/selftests/rtc/rtctest.c for an example usage of the -ioctl interface. diff --git a/Documentation/svga.txt b/Documentation/svga.txt deleted file mode 100644 index b6c2f9acca92..000000000000 --- a/Documentation/svga.txt +++ /dev/null @@ -1,249 +0,0 @@ -.. include:: - -================================= -Video Mode Selection Support 2.13 -================================= - -:Copyright: |copy| 1995--1999 Martin Mares, - -Intro -~~~~~ - -This small document describes the "Video Mode Selection" feature which -allows the use of various special video modes supported by the video BIOS. Due -to usage of the BIOS, the selection is limited to boot time (before the -kernel decompression starts) and works only on 80X86 machines. - -.. note:: - - Short intro for the impatient: Just use vga=ask for the first time, - enter ``scan`` on the video mode prompt, pick the mode you want to use, - remember its mode ID (the four-digit hexadecimal number) and then - set the vga parameter to this number (converted to decimal first). - -The video mode to be used is selected by a kernel parameter which can be -specified in the kernel Makefile (the SVGA_MODE=... line) or by the "vga=..." -option of LILO (or some other boot loader you use) or by the "vidmode" utility -(present in standard Linux utility packages). You can use the following values -of this parameter:: - - NORMAL_VGA - Standard 80x25 mode available on all display adapters. - - EXTENDED_VGA - Standard 8-pixel font mode: 80x43 on EGA, 80x50 on VGA. - - ASK_VGA - Display a video mode menu upon startup (see below). - - 0..35 - Menu item number (when you have used the menu to view the list of - modes available on your adapter, you can specify the menu item you want - to use). 0..9 correspond to "0".."9", 10..35 to "a".."z". Warning: the - mode list displayed may vary as the kernel version changes, because the - modes are listed in a "first detected -- first displayed" manner.

Warning: rdev and LILO don't support - hexadecimal numbers -- you have to convert it to decimal manually. - -Menu -~~~~ - -The ASK_VGA mode causes the kernel to offer a video mode menu upon -bootup. It displays a "Press to see video modes available, -to continue or wait 30 secs" message. If you press , you enter the -menu, if you press or wait 30 seconds, the kernel will boot up in -the standard 80x25 mode. - -The menu looks like:: - - Video adapter: - Mode: COLSxROWS: - 0 0F00 80x25 - 1 0F01 80x50 - 2 0F02 80x43 - 3 0F03 80x26 - .... - Enter mode number or ``scan``: - - tells what video adapter did Linux detect --- it's either a generic adapter name (MDA, CGA, HGC, EGA, VGA, VESA VGA [a VGA -with VESA-compliant BIOS]) or a chipset name (e.g., Trident). Direct detection -of chipsets is turned off by default as it's inherently unreliable due to -absolutely insane PC design. - -"0 0F00 80x25" means that the first menu item (the menu items are numbered -from "0" to "9" and from "a" to "z") is a 80x25 mode with ID=0x0f00 (see the -next section for a description of mode IDs). - - encourages you to enter the item number or mode ID -you wish to set and press . If the computer complains something about -"Unknown mode ID", it is trying to tell you that it isn't possible to set such -a mode. It's also possible to press only which leaves the current mode. - -The mode list usually contains a few basic modes and some VESA modes. In -case your chipset has been detected, some chipset-specific modes are shown as -well (some of these might be missing or unusable on your machine as different -BIOSes are often shipped with the same card and the mode numbers depend purely -on the VGA BIOS). - -The modes displayed on the menu are partially sorted: The list starts with -the standard modes (80x25 and 80x50) followed by "special" modes (80x28 and -80x43), local modes (if the local modes feature is enabled), VESA modes and -finally SVGA modes for the auto-detected adapter. - -If you are not happy with the mode list offered (e.g., if you think your card -is able to do more), you can enter "scan" instead of item number / mode ID. The -program will try to ask the BIOS for all possible video mode numbers and test -what happens then. The screen will be probably flashing wildly for some time and -strange noises will be heard from inside the monitor and so on and then, really -all consistent video modes supported by your BIOS will appear (plus maybe some -``ghost modes``). If you are afraid this could damage your monitor, don't use -this function. - -After scanning, the mode ordering is a bit different: the auto-detected SVGA -modes are not listed at all and the modes revealed by ``scan`` are shown before -all VESA modes. - -Mode IDs -~~~~~~~~ - -Because of the complexity of all the video stuff, the video mode IDs -used here are also a bit complex. A video mode ID is a 16-bit number usually -expressed in a hexadecimal notation (starting with "0x"). You can set a mode -by entering its mode directly if you know it even if it isn't shown on the menu. - -The ID numbers can be divided to those regions:: - - 0x0000 to 0x00ff - menu item references. 0x0000 is the first item. Don't use - outside the menu as this can change from boot to boot (especially if you - have used the ``scan`` feature). - - 0x0100 to 0x017f - standard BIOS modes.

All VESA modes should be autodetected and shown on the menu. - - 0x0900 to 0x09ff - Video7 special modes.

Currently available: - 0x0f00 standard 80x25, don't reset mode if already set (=FFFF) - 0x0f01 standard with 8-point font: 80x43 on EGA, 80x50 on VGA - 0x0f02 VGA 80x43 (VGA switched to 350 scanlines with a 8-point font) - 0x0f03 VGA 80x28 (standard VGA scans, but 14-point font) - 0x0f04 leave current video mode - 0x0f05 VGA 80x30 (480 scans, 16-point font) - 0x0f06 VGA 80x34 (480 scans, 14-point font) - 0x0f07 VGA 80x60 (480 scans, 8-point font) - 0x0f08 Graphics hack (see the VIDEO_GFX_HACK paragraph below) - - 0x1000 to 0x7fff - modes specified by resolution.

This is incorrect, the base applies only to FS and GS, not to the others.

SWIOTLB is used to satisfy that requirement if an IOMMU is not active (enabled or configured in passthrough mode). However, commit fafadcd16595 ("swiotlb: don't dip into swiotlb pool for coherent allocations") modified the coherent allocation support in SWIOTLB to use the DMA direct coherent allocation support. When an IOMMU is not active, this resulted in dma_alloc_coherent() failing for devices that didn't support DMA addresses that included the encryption bit. Addressing this requires changes to the force_dma_unencrypted() function in kernel/dma/direct.c. Since the function is now non-trivial and SME/SEV specific, update the DMA direct support to add an arch override for the force_dma_unencrypted() function. The arch override is selected when CONFIG_AMD_MEM_ENCRYPT is set. The arch override function resides in the arch/x86/mm/mem_encrypt.c file and forces unencrypted DMA when either SEV is active or SME is active and the device does not support DMA to physical addresses that include the encryption bit.

A new arch call back arch_ioremap_p4d_supported() is added which just maintains status quo (P4D huge map not supported) on x86, arm64 and powerpc. When HAVE_ARCH_HUGE_VMAP is enabled its just a simple check from the arch about the support, hence runtime effects are minimal.

Use a helper function in kprobes.h to unify them, based on the x86 code. This changes the behaviour for other architectures when preemption is enabled. Previously, they would have disabled preemption while calling the kprobe handler. However, preemption would be disabled if this fault was due to a kprobe, so we know the fault was not due to a kprobe handler and can simply return failure. This behaviour was introduced in commit a980c0ef9f6d ("x86/kprobes: Refactor kprobes_fault() like kprobe_exceptions_notify()") [anshuman.khandual@arm.com: export kprobe_fault_handler()] Link: http://lkml.kernel.org/r/1561133358-8876-1-git-send-email-anshuman.khandual@arm.com Link: http://lkml.kernel.org/r/1560420444-25737-1-git-send-email-anshuman.khandual@arm.com Signed-off-by: Anshuman Khandual Reviewed-by: Dave Hansen Cc: Michal Hocko Cc: Matthew Wilcox Cc: Mark Rutland Cc: Christophe Leroy Cc: Stephen Rothwell Cc: Andrey Konovalov Cc: Michael Ellerman Cc: Paul Mackerras Cc: Russell King Cc: Catalin Marinas Cc: Will Deacon Cc: Tony Luck Cc: Fenghua Yu Cc: Martin Schwidefsky Cc: Heiko Carstens Cc: Yoshinori Sato Cc: "David S.

Levin" Date: Tue, 16 Jul 2019 16:29:24 -0700 Subject: nds32: fix asm/syscall.h PTRACE_GET_SYSCALL_INFO is a generic ptrace API that lets ptracer obtain details of the syscall the tracee is blocked in. There are two reasons for a special syscall-related ptrace request. Firstly, with the current ptrace API there are cases when ptracer cannot retrieve necessary information about syscalls. Some examples include: * The notorious int-0x80-from-64-bit-task issue. See [1] for details. In short, if a 64-bit task performs a syscall through int 0x80, its tracer has no reliable means to find out that the syscall was, in fact, a compat syscall, and misidentifies it. * Syscall-enter-stop and syscall-exit-stop look the same for the tracer. Common practice is to keep track of the sequence of ptrace-stops in order not to mix the two syscall-stops up. But it is not as simple as it looks; for example, strace had a (just recently fixed) long-standing bug where attaching strace to a tracee that is performing the execve system call led to the tracer identifying the following syscall-exit-stop as syscall-enter-stop, which messed up all the state tracking. * Since the introduction of commit 84d77d3f06e7 ("ptrace: Don't allow accessing an undumpable mm"), both PTRACE_PEEKDATA and process_vm_readv become unavailable when the process dumpable flag is cleared. On such architectures as ia64 this results in all syscall arguments being unavailable for the tracer. Secondly, ptracers also have to support a lot of arch-specific code for obtaining information about the tracee. For some architectures, this requires a ptrace(PTRACE_PEEKUSER, ...) invocation for every syscall argument and return value. PTRACE_GET_SYSCALL_INFO returns the following structure: struct ptrace_syscall_info { __u8 op; /* PTRACE_SYSCALL_INFO_* */ __u32 arch __attribute__((__aligned__(sizeof(__u32)))); __u64 instruction_pointer; __u64 stack_pointer; union { struct { __u64 nr; __u64 args[6]; } entry; struct { __s64 rval; __u8 is_error; } exit; struct { __u64 nr; __u64 args[6]; __u32 ret_data; } seccomp; }; }; The structure was chosen according to [2], except for the following changes: * seccomp substructure was added as a superset of entry substructure * the type of nr field was changed from int to __u64 because syscall numbers are, as a practical matter, 64 bits * stack_pointer field was added along with instruction_pointer field since it is readily available and can save the tracer from extra PTRACE_GETREGS/PTRACE_GETREGSET calls * arch is always initialized to aid with tracing system calls such as execve() * instruction_pointer and stack_pointer are always initialized so they could be easily obtained for non-syscall stops * a boolean is_error field was added along with rval field, this way the tracer can more reliably distinguish a return value from an error value strace has been ported to PTRACE_GET_SYSCALL_INFO. Starting with release 4.26, strace uses PTRACE_GET_SYSCALL_INFO API as the preferred mechanism of obtaining syscall information.

This bug has to be fixed in order to extend the generic ptrace API with PTRACE_GET_SYSCALL_INFO request.

However, in some cases (kexec not fully working, benchmarking) we want to disable PV extensions. We have "xen_nopv" for that purpose but only for XEN. For a consistent admin experience a common command line parameter "nopv" set across all PV guest implementations is a better choice. There are guest types which just won't work without PV extensions, like Xen PV, Xen PVH and jailhouse. add a "ignore_nopv" member to struct hypervisor_x86 set to true for those guest types and call the detect functions only if nopv is false or ignore_nopv is true.

If PVH guest boots up via the Xen-PVH boot entry, xen_pvh is set early, we know it's PVH guest and ignore "nopv" parameter directly. If PVH guest boots up via the normal boot entry same as HVM guest, it's hard to distinguish PVH and HVM guest at that time. In this case, we have to panic early if PVH is detected and nopv is enabled to avoid a worse situation later. Remove static from bool_x86_init_noop/x86_op_int_noop so they could be used globally. Move xen_platform_hvm() after xen_hvm_guest_late_init() to avoid compile error.

On Linux we use privilege level 0 for the kernel and privilege level 3 for user-space. So userspace should not be allowed to modify IAOQ0 or IAOQ1 of a ptraced process to change it's privilege level to e.g. 0 to try to gain kernel privileges.

This breaks RISC-V builds, since RISC-V's cacheflush.h includes the generic cacheflush.h and then undefines the macros to be overridden. Fix by copying the subset of the no-op functions that are reused from the generic cacheflush.h into the RISC-V cacheflush.h, and dropping the include of the generic cacheflush.h.

Now, it iterates over memory blocks. Rename the function, fixup the documentation. Also, pass start+size instead of PFNs, which is what most callers already have at hand. (we'll rework link_mem_sections() most probably soon) Follow-up patches will rework, simplify, and move walk_memory_blocks() to drivers/base/memory.c. Note: walk_memory_blocks() only works correctly right now if the start_pfn is aligned to a section start. This is the case right now, but we'll generalize the function in a follow up patch so the semantics match the documentation.

This function uses the extra1 and extra2 members from struct ctl_table as minimum and maximum allowed value. On sysctl handler declaration, in every source file there are some readonly variables containing just an integer which address is assigned to the extra1 and extra2 members, so the sysctl range is enforced. The special values 0, 1 and INT_MAX are very often used as range boundary, leading duplication of variables like zero=0, one=1, int_max=INT_MAX in different source files: $ git grep -E '\.extra[12].*&(zero|one|int_max)' |wc -l 248 Add a const int array containing the most commonly used values, some macros to refer more easily to the correct array member, and use them instead of creating a local one for every object file.

The asid allocator use five level check to reduce the cost of switch_mm. 1. Check if the asid version is the same (it's general) 2. Check reserved_asid which is set in rollover flush_context() and key point is to keep the same bit position with the current asid version instead of input version. 3. Check if the position of bitmap is free then it could be set & used directly. 4. find_next_zero_bit() (a little performance cost) 5. flush_context (this is the worst cost with increase current asid version) Check is level by level and cost is also higher with the next level. The reserved_asid and bitmap mechanism prevent unnecessary find_next_zero_bit(). The atomic 64 bit asid is also suitable for 32-bit system and it won't cost a lot in 1th 2th 3th level check. The operation of set/clear mm_cpumask was removed in arm64 compared to arm32. It seems no side effect on current arm64 system, but from software meaning it's wrong. Although csky also needn't it, we add it back for csky. The asid_per_ctxt is no use for csky and it reserves the lowest bits for other use, maybe: trust zone ? Ok, just keep it in csky copy. Seems it also could be used by other archs and it's worth to move asid code to generic in future.

Overlays are addressed GPA but are not included in the normal GPA map maintained internally by the hypervisor. Conceptually, they exist in a separate map that overlays the GPA map. If a page within the GPA space is overlaid, any SPA page mapped to the GPA page is effectively "obscured" and generally unreachable by the virtual processor through processor memory accesses. If an overlay page is disabled, the underlying GPA page is "uncovered", and an existing mapping becomes accessible to the guest." SPA = System Physical Address = the final real physical address. When a CPU (e.g. CPU1) is onlined, hv_cpu_init() allocates the VP ASSIST PAGE and enables the EOI optimization for this CPU by writing the MSR HV_X64_MSR_VP_ASSIST_PAGE. From now on, hvp->apic_assist belongs to the special SPA page, and this CPU *always* uses hvp->apic_assist (which is shared with the hypervisor) to decide if it needs to write the EOI MSR. When a CPU is offlined then on the outgoing CPU: 1. hv_cpu_die() disables the EOI optimizaton for this CPU, and from now on hvp->apic_assist belongs to the original "normal" SPA page; 2. the remaining work of stopping this CPU is done 3. this CPU is completely stopped. Between 1 and 3, this CPU can still receive interrupts (e.g. reschedule IPIs from CPU0, and Local APIC timer interrupts), and this CPU *must* write the EOI MSR for every interrupt received, otherwise the hypervisor may not deliver further interrupts, which may be needed to completely stop the CPU. So, after the EOI optimization is disabled in hv_cpu_die(), it's required that the hvp->apic_assist's bit0 is zero, which is not guaranteed by the current allocation mode because it lacks __GFP_ZERO. As a consequence the bit might be set and interrupt handling would not write the EOI MSR causing interrupt delivery to become stuck. Add the missing __GFP_ZERO to the allocation. Note 1: after the "normal" SPA page is allocted and zeroed out, neither the hypervisor nor the guest writes into the page, so the page remains with zeros. Note 2: see Section 10.3.5 "EOI Assist" for the details of the EOI optimization. When the optimization is enabled, the guest can still write the EOI MSR register irrespective of the "No EOI required" value, but that's slower than the optimized assist based variant.

There is no hardware virtual timer on Intel for guest like ARM, so both programming timer in guest and the emulated timer fires incur vmexits. This patch tries to avoid vmexit when the emulated timer fires, at least in dedicated instance scenario when nohz_full is enabled. In that case, the emulated timers can be offload to the nearest busy housekeeping cpus since APICv has been found for several years in server processors. The guest timer interrupt can then be injected via posted interrupts, which are delivered by the housekeeping cpu once the emulated timer fires. The host should tuned so that vCPUs are placed on isolated physical processors, and with several pCPUs surplus for busy housekeeping. If disabled mwait/hlt/pause vmexits keep the vCPUs in non-root mode, ~3% redis performance benefit can be observed on Skylake server, and the number of external interrupt vmexits drops substantially.

This is AMD errata 1096 and it happens because CPU microcode reading instruction bytes incorrectly attempts to read code as implicit supervisor-mode data accesses (that is, just like it would read e.g. a TSS), which are susceptible to SMAP faults. The microcode reads CS:RIP and if it is a user-mode address according to the page tables, the processor gives up and returns no instruction bytes. In this case, GuestIntrBytes field of the VMCB on a VMEXIT will incorrectly return 0 instead of the correct guest instruction bytes. Current KVM code attemps to detect and workaround this errata, but it has multiple issues: 1) It mistakenly checks if guest CR4.SMAP=0 instead of guest CR4.SMAP=1, which is required for encountering a SMAP fault. 2) It assumes SMAP faults can only occur when guest CPL==3. However, in case guest CR4.SMEP=0, the guest can execute an instruction which reside in a user-accessible page with CPL<3 priviledge. If this instruction raise a #NPF on it's data access, then CPU DecodeAssist microcode will still encounter a SMAP violation. Even though no sane OS will do so (as it's an obvious priviledge escalation vulnerability), we still need to handle this semanticly correct in KVM side. Note that (2) *is* a useful optimization, because CR4.SMAP=1 is an easy triggerable condition and guests usually enable SMAP together with SMEP. If the vCPU has CR4.SMEP=1, the errata could indeed be encountered onlt at guest CPL==3; otherwise, the CPU would raise a SMEP fault to guest instead of #NPF. We keep this condition to avoid false positives in the detection of the errata. In addition, to avoid future confusion and improve code readbility, include details of the errata in code and not just in commit message.

Most smp_call_function_many calls are synchronous, so the IPI target vCPUs are also good yield candidates. This patch introduces vcpu->ready to boost vCPUs during wakeup and interrupt delivery time; unlike s390 we do not reuse vcpu->preempted so that voluntarily preempted vCPUs are taken into account by kvm_vcpu_on_spin, but vmx_vcpu_pi_put is not affected (VT-d PI handles voluntary preemption separately, in pi_pre_block).

CR2 is saved early in the entry code in RDX, which is the third argument to the fault handling functions. But it missed that between saving and invoking the fault handler enter_from_user_mode() can be called. RDX is a caller saved register so the invoked function can freely clobber it with the obvious consequences. The TRACE_IRQS_OFF call is safe as it calls through the thunk which preserves RDX, but TRACE_IRQS_OFF_DEBUG is not because it also calls into C-code outside of the thunk. Store CR2 in R12 instead which is a callee saved register and move R12 to RDX just before calling the fault handler.
