| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From commit e147133a42cb ("ACPI / APEI: Make hest.c manage the estatus memory pool") was merged, ghes_init() relies on acpi_hest_init() to manage the estatus memory pool. On the other hand, ghes_init() relies on sdei_init() to detect the SDEI version and (un)register events. The dependencies are as follows: ghes_init() => acpi_hest_init() => acpi_bus_init() => acpi_init() ghes_init() => sdei_init() HEST is not PCI-specific and initcall ordering is implicit and not well-defined within a level. Based on above, remove acpi_hest_init() from acpi_pci_root_init() and convert ghes_init() and sdei_init() from initcalls to explicit calls in the following order: acpi_hest_init() ghes_init() sdei_init() Signed-off-by: Shuai Xue <xueshuai@linux.alibaba.com> Signed-off-by: Rafael J.

* | sysfb: Enable boot time VESA graphic mode selectionMichal Suchanek2022-03-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since switch to simplefb/simpledrm VESA graphic mode selection with vga= kernel parameter is no longer available with legacy BIOS. The x86 realmode boot code enables the VESA graphic modes when option FB_BOOT_VESA_SUPPORT is enabled. This option is selected by vesafb but not simplefb/simpledrm. To enable use of VESA modes with simplefb in legacy BIOS boot mode drop dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix. Select the option from sysfb rather than the drivers that depend on it. The BOOT_VESA_SUPPORT is not specific to framebuffer but rather to x86 platform, move it from fbdev to x86 Kconfig.

Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.

|/ | | | | | | | | | | | | | wm_adsp originally provided firmware loading on some audio DSP and was implemented as an ASoC codec driver. However, the firmware loading now covers a wider range of DSP cores and peripherals containing them, beyond just audio. So it needs to be available to non-audio drivers.

An out-of-bounds error related to the cooling devices of the AOSS driver is corrected. The binding is converted to YAML and a generic compatible is introduced to reduce the driver churn. The GENI wrapper gains a helper function used in I2C and SPI for switching the serial engine hardware to use the wrapper's DMA-engine.

This is true for most architectures, but at least the following do not: arc, m68k, microblaze, openrisc, parisc and s390. By attempting to make this compile testeable on all architectures, it leads to linking errors as reported by the kernel test robot for parisc: All errors (new ones prefixed by >>): hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init': (.init.text+0x24): undefined reference to `screen_info' >> hppa-linux-ld: (.init.text+0x28): undefined reference to `screen_info' To prevent these errors only allow sysfb to be built on systems that are going to need it, which are x86 BIOS and EFI. The EFI Kconfig symbol is used instead of (ARM || ARM64 || RISC) because some of these architectures only declare a struct screen_info if EFI is enabled. And also, because the SYSFB code is only used for EFI on these architectures. For !EFI the "simple-framebuffer" device is registered by OF when parsing the Device Tree Blob (if a DT node for this was defined).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The register_gop_device() function registers an "efi-framebuffer" platform device to match against the efifb driver, to have an early framebuffer for EFI platforms. But there is already support to do exactly the same by the Generic System Framebuffers (sysfb) driver. This used to be only for X86 but it has been moved to drivers/firmware and could be reused by other architectures. Also, besides supporting registering an "efi-framebuffer", this driver can register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers on non-X86 EFI platforms. For example, on aarch64 these drivers can only be used with DT and doesn't have code to register a "simple-frambuffer" platform device when booting with EFI. For these reasons, let's remove the register_gop_device() duplicated code and instead move the platform specific logic that's there to sysfb driver.

In the Normal world, a partition could be a VM when the Virtualization extension is enabled or the kernel itself.

Similarly, different drivers requiring FFA transport can be registered on the same bus. We can match the device and drivers using UUID. This is mostly for the in-kernel users with FFA drivers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and SoC-part. Up to a point that N5X uses the same DTSI as Agilex. From the Linux kernel point of view these are flavors of the same architecture so there is no need for three top-level arm64 architectures. Simplify this by merging all three architectures into ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries. The side effect is that the INTEL_STRATIX10_SERVICE will now be available for both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for 64-bit.

|/ | | | | | | | | | | | | | | | | | | | | SMCCC v1.0 lacked discoverability of version and features. To accelerate adoption of few mitigations and protect systems more rapidly from various vulnerability, PSCI v1.0 was updated to add SMCCC discovery mechanism though the PSCI firmware implementation of PSCI_FEATURES(SMCCC_VERSION) which returns success on firmware compliant to SMCCC v1.1 and above. This inturn makes SMCCC v1.1 and above dependent on ARM_PSCI_FW for backward compatibility. Let us introduce a new hidden config for the same to build more features on top of SMCCC v1.1 and above.

| | | | | | | | | | | | | | | | | | | | | Dynamically support SMCCCC and legacy conventions by detecting which convention to use at runtime. qcom_scm_call_atomic and qcom_scm_call can then be moved in qcom_scm.c and use underlying convention backend as appropriate. Thus, rename qcom_scm-64,-32 to reflect that they are backends for -smc and -legacy, respectively. Also add support for making SCM calls earlier than when SCM driver probes to support use cases such as qcom_scm_set_cold_boot_addr. Support is added by lazily initializing the convention and guarding the query with a spin lock. The limitation of these early SCM calls is that they cannot use DMA, as in the case of >4 arguments for SMC convention and any non-atomic call for legacy convention.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Intel Remote System Update (RSU) driver exposes interfaces access through the Intel Service Layer to user space via sysfs interface. The RSU interfaces report and control some of the optional RSU features on Intel Stratix 10 SoC. The RSU feature provides a way for customers to update the boot configuration of a Intel Stratix 10 SoC device with significantly reduced risk of corrupting the bitstream storage and bricking the system.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a driver to communicate with the firmware running on the secure processor of the Turris Mox router, enabling the kernel to retrieve true random numbers from the Entropy Bit Generator and to read some information burned into eFuses when device was manufactured: and to sign messages with the ECDSA private key burned into each Turris Mox device when manufacturing. This also adds support to read other information burned into eFuses: - serial number - board version - MAC addresses - RAM size - ECDSA public key (this is not read directly from eFuses, rather it is computed by the firmware as pair to the burned private key) The source code of the firmware is open source and can be found at https://gitlab.labs.nic.cz/turris/mox-boot-builder/tree/master/wtmi The firmware is also able to, on demand, sign messages with the burned ECDSA private key, but since Linux's akcipher API is not yet stable (and therefore not exposed to userspace via netlink), this functionality is not supported yet.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iscsi_ibft can use ACPI to find the iBFT entry during bootup, currently, ISCSI_IBFT depends on ISCSI_IBFT_FIND which is a X86 legacy way to find the iBFT by searching through the low memory. This patch changes the dependency so that other arch like ARM64 can use ISCSI_IBFT as long as the arch supports ACPI. ibft_init() needs to use the global variable ibft_addr declared in iscsi_ibft_find.c. A #ifndef CONFIG_ISCSI_IBFT_FIND is needed to declare the variable if CONFIG_ISCSI_IBFT_FIND is not selected. Moving ibft_addr into the iscsi_ibft.c does not work because if ISCSI_IBFT is selected as a module, the arch/x86/kernel/setup.c won't be able to find the variable at compile time.
