Improvements for the flamegraph python script, including: # - Display perf.data header # - Display PIDs of user stacks # - Added option to change color scheme # - Default to blue/green color scheme to improve accessibility # - Correctly identify kernel stacks when debuginfo is available # # - Improvements for 'perf bench futex': # - Add --mlockall parameter # - Add --broadcast and --pi to the 'requeue' sub benchmark # # - Add support for PMU aliases. # # - Introduce an ARM Coresight ETE decoder. # # - Add a 'perf bench' entry for evlist open/close operations, to help # quantify improvements with multithreading 'perf record'. # # - Allow reporting the [un]throttle PERF_RECORD_ meta event in 'perf # script's python scripting. # # - Add a 'perf test' entry for PMU aliases. # # - Add a 'perf test' entry for 'perf record/perf report/perf script' # pipe mode. # # Fixes: # # - perf script dlfilter (API for filtering via dynamically loaded # shared object introduced in v5.14) fixes and a 'perf test' entry # for it. # # - Fix get_current_dir_name() compilation on Android. # # - Fix issues with asciidoc and double dashes uses. # # - Fix memory leaks in the BTF handling code. # # - Fix leftover problems in the Documentation from the infrastructure # originally lifted from the git codebase. # # - Fix *probe_vfs_getname.sh 'perf test' failures. # # - Handle fd gaps in 'perf test's test__dso_data_reopen(). # # - Make sure to show disasembly warnings for 'perf annotate --stdio'. # # - Fix output from pipe to file and vice-versa in 'perf # record/report/script'. # # - Correct 'perf data -h' output. # # - Fix wrong comm in system-wide mode with 'perf record --delay'. # # - Do not allow --for-each-cgroup without cpu in 'perf stat' # # - Make 'perf test --skip' work on shell tests. # # - Fix libperf's verbose printing. # # Misc improvements: # # - Preparatory patches for multithreading various 'perf record' phases # (synthesizing, opening, recording, etc). # # - Add sparse context/locking annotations in compiler-types.h, also to # help with the multithreading effort. # # - Optimize the generation of the arch specific erno tables used in # 'perf trace'. # # - Optimize libperf's perf_cpu_map__max(). # # - Improve ARM's CoreSight warnings. # # - Report collisions in AUX records. # # - Improve warnings for the LLVM 'perf test' entry. # # - Improve the PMU events 'perf test' codebase. # # - perf test: Do not compare overheads in the zstd comp test # # - Better support annotation on ARM. # # - Update 'perf trace's cmd string table to decode sys_bpf() first # arg. # # Vendor events: # # - Add JSON events and metrics for Intel's Ice Lake, Tiger Lake and # Elhart Lake. # # - Update JSON eventsand metrics for Intel's Cascade Lake and Sky Lake # servers. # # Hardware tracing: # # - Improvements for the ARM hardware tracing auxtrace support" # # * tag 'perf-tools-for-v5.15-2021-09-04' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (130 commits) # perf tests: Add test for PMU aliases # perf pmu: Add PMU alias support # perf session: Report collisions in AUX records # perf script python: Allow reporting the [un]throttle PERF_RECORD_ meta event # perf build: Report failure for testing feature libopencsd # perf cs-etm: Show a warning for an unknown magic number # perf cs-etm: Print the decoder name # perf cs-etm: Create ETE decoder # perf cs-etm: Update OpenCSD decoder for ETE # perf cs-etm: Fix typo # perf cs-etm: Save TRCDEVARCH register # perf cs-etm: Refactor out ETMv4 header saving # perf cs-etm: Initialise architecture based on TRCIDR1 # perf cs-etm: Refactor initialisation of decoder params. # tools build: Fix feature detect clean for out of source builds # perf evlist: Add evlist__for_each_entry_from() macro # perf evsel: Handle precise_ip fallback in evsel__open_cpu() # perf evsel: Move bpf_counter__install_pe() to success path in evsel__open_cpu() # perf evsel: Move test_attr__open() to success path in evsel__open_cpu() # perf evsel: Move ignore_missing_thread() to fallback code # ... # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 27151f177827d478508e756c7657273261aaf8a9 # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- randconfig # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # < make -s -j 120 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- help # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- olddefconfig .config:5740:warning: override: reassigning to symbol PREVENT_FIRMWARE_BUILD # make -s -j 120 ARCH=arm64 O=/kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- /kisskb/src/arch/arm64/kvm/hyp/nvhe/Makefile:58: FORCE prerequisite is missing /kisskb/src/kernel/trace/trace_osnoise.c: In function 'start_kthread': /kisskb/src/kernel/trace/trace_osnoise.c:1515:8: warning: 'main' is usually a function [-Wmain] void *main = osnoise_main; ^~~~ /kisskb/src/block/mq-deadline.c:274:12: warning: 'dd_queued' defined but not used [-Wunused-function] static u32 dd_queued(struct deadline_data *dd, enum dd_prio prio) ^~~~~~~~~ /kisskb/src/drivers/thunderbolt/test.c: In function 'tb_test_credit_alloc_dma_multiple': /kisskb/src/drivers/thunderbolt/test.c:2207:1: warning: the frame size of 3152 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ /kisskb/src/drivers/thunderbolt/test.c: In function 'tb_test_credit_alloc_all': /kisskb/src/drivers/thunderbolt/test.c:2367:1: warning: the frame size of 7168 bytes is larger than 2048 bytes [-Wframe-larger-than=] } ^ Completed OK # rm -rf /kisskb/build/linus-rand_arm64-randconfig_arm64-gcc8 # Build took: 0:02:49.726216
