For that, it introduced a new exit reason. However, it did not update the trace point array that gives human readable names to these exit reasons inside the trace log. Let's fix that up after the fact, so that trace logs are pretty even when we get user space MMIO traps on ARM.

Statistics reported through these new VM events will help in performance debugging. 1. THP_MIGRATION_SUCCESS 2. THP_MIGRATION_FAILURE 3. THP_MIGRATION_SPLIT In addition, these new events also update normal page migration statistics appropriately via PGMIGRATE_SUCCESS and PGMIGRATE_FAILURE. While here, this updates current trace event 'mm_migrate_pages' to accommodate now available THP statistics.

Before this change, if an interrupt came in while recording another event, and that interrupt also had an event, those events would all have the same time stamp as the event it interrupted. Now, with the new design, those events will have a unique time stamp and rightfully display the time for those events that were recorded while interrupting another event. - Bootconfig how has an "override" operator that lets the users have a default config, but then add options to override the default. - A fix was made to properly filter function graph tracing to the ftrace PIDs. This came in at the end of the -rc cycle, and needs to be backported. - Several clean ups, performance updates, and minor fixes as well. * tag 'trace-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (39 commits) tracing: Add trace_array_init_printk() to initialize instance trace_printk() buffers kprobes: Fix compiler warning for !CONFIG_KPROBES_ON_FTRACE tracing: Use trace_sched_process_free() instead of exit() for pid tracing bootconfig: Fix to find the initargs correctly Documentation: bootconfig: Add bootconfig override operator tools/bootconfig: Add testcases for value override operator lib/bootconfig: Add override operator support kprobes: Remove show_registers() function prototype tracing/uprobe: Remove dead code in trace_uprobe_register() kprobes: Fix NULL pointer dereference at kprobe_ftrace_handler ftrace: Fix ftrace_trace_task return value tracepoint: Use __used attribute definitions from compiler_attributes.h tracepoint: Mark __tracepoint_string's __used trace : Have tracing buffer info use kvzalloc instead of kzalloc tracing: Remove outdated comment in stack handling ftrace: Do not let direct or IPMODIFY ftrace_ops be added to module and set trampolines ftrace: Setup correct FTRACE_FL_REGS flags for module tracing/hwlat: Honor the tracing_cpumask tracing/hwlat: Drop the duplicate assignment in start_kthread() tracing: Save one trace_event->type by using __TRACE_LAST_TYPE ...

This risks breaking userspace, though we believe it is unused in practice. - A bug fix for, and then the removal of, our custom stack expansion checking. We now allow stack expansion up to the rlimit, like other architectures. - Remove the remnants of our (previously disabled) topology update code, which tried to react to NUMA layout changes on virtualised systems, but was prone to crashes and other problems. - Add PMU support for Power10 CPUs. - A change to our signal trampoline so that we don't unbalance the link stack (branch return predictor) in the signal delivery path. - Lots of other cleanups, refactorings, smaller features and so on as usual.

PROT_SAO was used by specialised system software (Lx86) that has been discontinued for about 7 years, and is not thought to be used elsewhere, so removal should not cause problems. We rather remove it than keep support for older processors, because live migrating guest partitions to newer processors may not be possible if SAO is in use (or worse allowed with silent races). - PROT_SAO stays in the uapi header so code using it would still build. - arch_validate_prot() is removed, the generic version rejects PROT_SAO so applications would get a failure at mmap() time.

A larger driver for the Tegra memory controller that was accidentally missed for v5.8 is now added. - reset controllers: Only minor updates to drivers/reset this time - firmware: The "turris mox" firmware driver gains support for signed firmware blobs The tegra firmware driver gets extended to export some debug information Various updates to i.MX firmware drivers, mostly cosmetic - ARM SCMI/SCPI: A new mechanism for platform notifications is added, among a number of minor changes. - optee: Probing of the TEE bus is rewritten to better support detection of devices that depend on the tee-supplicant user space. A new firmware based trusted platform module (fTPM) driver is added based on OP-TEE - SoC attributes: A new driver is added to provide a generic soc_device for identifying a machine through the SMCCC ARCH_SOC_ID firmware interface rather than by probing SoC family specific registers.

There are also a number of updates to SoC specific drivers, the main ones are: - Mediatek cmdq driver gains a few in-kernel interfaces - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding support for additional SoC variants - The Qualcomm GENI core code gains interconnect path voting and performance level support, and integrating this into a number of device drivers. - A new driver for Samsung Exynos5800 voltage coupler for - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC specific device drivers - Updates to the TI K3 Ring Accelerator driver" * tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (164 commits) soc: qcom: geni: Fix unused label warning soc: qcom: smd-rpm: Fix kerneldoc memory: jz4780_nemc: Only request IO memory the driver will use soc: qcom: pdr: Reorder the PD state indication ack MAINTAINERS: Add Git repository for memory controller drivers memory: brcmstb_dpfe: Fix language typo memory: samsung: exynos5422-dmc: Correct white space issues memory: samsung: exynos-srom: Correct alignment memory: pl172: Enclose macro argument usage in parenthesis memory: of: Correct kerneldoc memory: omap-gpmc: Fix language typo memory: omap-gpmc: Correct white space issues memory: omap-gpmc: Use 'unsigned int' for consistency memory: omap-gpmc: Enclose macro argument usage in parenthesis memory: omap-gpmc: Correct kerneldoc memory: mvebu-devbus: Align with open parenthesis memory: mvebu-devbus: Add missing braces to all arms of if statement memory: bt1-l2-ctl: Add blank lines after declarations soc: TI knav_qmss: make symbol 'knav_acc_range_ops' static firmware: ti_sci: Replace HTTP links with HTTPS ones ...

SCMI protocol specification allows the platform to signal events to the interested agents via notification messages. We are adding support for the dispatch and delivery of such notifications to the interested users inside the kernel. Other than that, there are minor changes like checking and using the fast_switch capability quering the firmware instead of doing it unconditionally(using polling mode transfer), cosmetic trace update, use of HAVE_ARM_SMCCC_DISCOVERY instead of ARM_PSCI_FW and a fix in scmi clock registration logic for all the clocks with discrete rates. * tag 'scmi-updates-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Remove fixed size fields from reports/scmi_event_header firmware: arm_scmi: Remove unneeded __packed attribute firmware: arm_scmi: Remove zero-length array in SCMI notifications firmware: arm_scmi: Provide a missing function param description clk: scmi: Fix min and max rate when registering clocks with discrete rates firmware: arm_scmi: Keep the discrete clock rates sorted firmware: arm_scmi: Add base notifications support firmware: arm_scmi: Add reset notifications support firmware: arm_scmi: Add sensor notifications support firmware: arm_scmi: Add perf notifications support firmware: arm_scmi: Add power notifications support firmware: arm_scmi: Enable notification core firmware: arm_scmi: Add notification dispatch and delivery firmware: arm_scmi: Add notification callbacks-registration firmware: arm_scmi: Add notification protocol-registration firmware: arm_scmi: Fix SCMI genpd domain probing firmware: arm_scmi: Use HAVE_ARM_SMCCC_DISCOVERY instead of ARM_PSCI_FW cpufreq: arm_scmi: Set fast_switch_possible conditionally firmware: arm_scmi: Add fast_switch_possible() interface firmware: arm_scmi: Use signed integer to report transfer status Link: https://lore.kernel.org/r/20200713161410.12324-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

It may also miss to emit any timeouts that happen in the driver resulting in emitting garbage in the status field in those scenarios. Let us use signed integer so that error values are emitted out after they are mapped from firmware error formats to standard linux error codes. While at this, also include any timeouts in the driver itself.

The tracepoint is accessed by loading an external kernel module. An example module (forked from Qais' module and including the pelt related tracepoints) can be found at: https://github.com/auldp/tracepoints-helpers.git A script to turn the trace-cmd report output into a heatmap plot can be found at: https://github.com/jirvoz/plot-nr-running The tracepoints are added to add_nr_running() and sub_nr_running() which are in kernel/sched/sched.h.

Rename rcu_invoke_kfree_callback() to rcu_invoke_kvfree_callback(), as well as the associated trace events, so the rcu_kfree_callback(), becomes rcu_kvfree_callback(). The reason is to be aligned with kvfree() notation. 2. Rename __is_kfree_rcu_offset to __is_kvfree_rcu_offset. All RCU paths use kvfree() now instead of kfree(), thus rename it. 3. Rename kfree_call_rcu() to the kvfree_call_rcu(). The reason is, it is capable of freeing vmalloc() memory now. Do the same with __kfree_rcu() macro, it becomes __kvfree_rcu(), the goal is the same.
