ceea279f93760767c0e654341829334a1c881a08 - perf kvm stat: Remove use of the arch directory

Tue, 03 Feb 2026 18:26:36 +0000

perf kvm stat: Remove use of the arch directory`perf kvm stat` supports record and report options.By using the arch directory a report for a different machine type cannotbe supported.Move the kvm-stat code out of the arch directory and intoutil/kvm-stat-arch following the pattern of perf-regs and dwarf-regs.Avoid duplicate symbols by renaming functions to have the architecturename within them.For global variables, wrap them in an architecture specific function.Selecting the architecture to use with `perf kvm stat` is selected byEM_HOST, ie no different than before the change.Later the ELF machine can be determined from the session or a headerfeature (ie EM_HOST at the time of the record).The build and #define HAVE_KVM_STAT_SUPPORT is now redundant so removeacross Makefiles and in the build.Opportunistically constify architectural structs and arrays.Signed-off-by: Ian Rogers Cc: Aditya Bodkhe Cc: Adrian Hunter Cc: Albert Ou Cc: Alexander Shishkin Cc: Alexandre Ghiti Cc: Andi Kleen Cc: Andrew Jones Cc: Anubhav Shelat Cc: Anup Patel Cc: Athira Rajeev Cc: Blake Jones Cc: Chun-Tse Shao Cc: Dapeng Mi Cc: Dmitriy Vyukov Cc: Howard Chu Cc: Ingo Molnar Cc: James Clark Cc: Jiri Olsa Cc: John Garry Cc: Leo Yan Cc: Namhyung Kim Cc: Palmer Dabbelt Cc: Paul Walmsley Cc: Peter Zijlstra Cc: Quan Zhou Cc: Shimin Guo Cc: Swapnil Sapkal Cc: Thomas Falcon Cc: Will Deacon Cc: Yunseong Kim Signed-off-by: Arnaldo Carvalho de Melo List of files: /linux/tools/perf/arch/powerpc/Makefile

Wed, 26 Mar 2025 12:42:07 +0000

Merge branch 'for-6.15/amd_sfh' into for-linusFrom: Mario Limonciello Some platforms include a human presence detection (HPD) sensor. Whenenabled and a user is detected a wake event will be emitted from thesensor fusion hub that software can react to.Example use cases are "wake from suspend on approach" or to "lockwhen leaving".This is currently enabled by default on supported systems, but userscan't control it. This essentially means that wake on approach isenabled which is a really surprising behavior to users that don'texpect it.Instead of defaulting to enabled add a sysfs knob that users canuse to enable the feature if desirable and set it to disabled bydefault.

Merge tag 'perf-tools-for-v6.14-2025-01-21' of git://git.kernel.org/pub/scm/linux/kernel/git/perf/perf-toolsPull perf-tools updates from Namhyung Kim: "There are a lot of changes in the perf tools in this cycle. build: - Use generic syscall table to generate syscall numbers on supported archs - This also enables to get rid of libaudit which was used for syscall numbers - Remove python2 support as it's deprecated for years - Fix issues on static build with libzstd perf record: - Intel-PT supports "aux-action" config term to pause or resume tracing in the aux-buffer. Users can start the intel_pt event as "started-paused" and configure other events to control the Intel-PT tracing: # perf record --kcore -e intel_pt/aux-action=start-paused/ \ -e syscalls:sys_enter_newuname/aux-action=resume/ \ -e syscalls:sys_exit_newuname/aux-action=pause/ -- uname This requires kernel support (which was added in v6.13) perf lock: - 'perf lock contention' command has an ability to symbolize locks in dynamically allocated objects using slab cache name when it runs with BPF.

Also it's possible to specify max and min latency for the linear buckets: # perf ftrace latency -abn -T switch_mm_irqs_off --bucket-range=100 \ --min-latency=200 --max-latency=800 -- sleep 1 # DURATION | COUNT | GRAPH | 0 - 200 ns | 186 | ### | 200 - 300 ns | 256 | ##### | 300 - 400 ns | 364 | ####### | 400 - 500 ns | 223 | #### | 500 - 600 ns | 111 | ## | 600 - 700 ns | 41 | | 700 - 800 ns | 141 | ## | 800 - ... ns | 169 | ### | # statistics (in nsec) total time: 2162212 avg time: 967 max time: 16817 min time: 132 count: 2236 - As you can see in the above example, it nows shows the statistics at the end so that users can see the avg/max/min latencies easily - 'perf ftrace profile' command has --graph-opts option like 'perf ftrace trace' so that it can control the tracing behaviors in the same way. For example, it can limit the function call depth or threshold perf script: - Improve physical memory resolution in 'mem-phys-addr' script by parsing /proc/iomem file # perf script mem-phys-addr -- find / ...

This would be helpful to see if it's flaky - Add 'parse_events' method to Python perf extension module, so that users can use the same event parsing logic in the python code. One more step towards implementing perf tools in Python. :) - Support opening tracepoint events without libtraceevent.
