- cgroup improvements for 'perf stat', allowing for compact specification of events and cgroups in the command line. - Support per thread topdown metrics in 'perf stat'. - Support sample-read topdown metric group in 'perf record' - Show start of latency in addition to its start in 'perf sched latency'. - Add min, max to 'perf script' futex-contention output, in addition to avg. - Allow usage of 'perf_event_attr->exclusive' attribute via the new ':e' event modifier. - Add 'snapshot' command to 'perf record --control', using it with Intel PT. - Support FIFO file names as alternative options to 'perf record --control'. - Introduce branch history "streams", to compare 'perf record' runs with 'perf diff' based on branch records and report hot streams. - Support PE executable symbol tables using libbfd, to profile, for instance, wine binaries. - Add filter support for option 'perf ftrace -F/--funcs'. - Allow configuring the 'disassembler_style' 'perf annotate' knob via 'perf config' - Update CascadelakeX and SkylakeX JSON vendor events files. - Add support for parsing perchip/percore JSON vendor events. - Add power9 hv_24x7 core level metric events. - Add L2 prefetch, ITLB instruction fetch hits JSON events for AMD zen1. - Enable Family 19h users by matching Zen2 AMD vendor events. - Use debuginfod in 'perf probe' when required debug files not found locally. - Display negative tid in non-sample events in 'perf script'. - Make GTK2 support opt-in - Add build test with GTK+ - Add missing -lzstd to the fast path feature detection - Add scripts to auto generate 'mmap', 'mremap' string<->id tables for use in 'perf trace'. - Show python test script in verbose mode. - Fix uncore metric expressions - Msan uninitialized use fixes. - Use condition variables in 'perf bench numa' - Autodetect python3 binary in systems without python2. - Support md5 build ids in addition to sha1. - Add build id 'perf test' regression test. - Fix printable strings in python3 scripts. - Fix off by ones in 'perf trace' in arches using libaudit. - Fix JSON event code for events referencing std arch events. - Introduce 'perf test' shell script for Arm CoreSight testing. - Add rdtsc() for Arm64 for used in the PERF_RECORD_TIME_CONV metadata event and in 'perf test tsc'. - 'perf c2c' improvements: Add "RMT Load Hit" metric, "Total Stores", fixes and documentation update. - Fix usage of reloc_sym in 'perf probe' when using both kallsyms and debuginfo files. - Do not print 'Metric Groups:' unnecessarily in 'perf list' - Refcounting fixes in the event parsing code. - Add expand cgroup event 'perf test' entry. - Fix out of bounds CPU map access when handling armv8_pmu events in 'perf stat'. - Add build-id injection 'perf bench' benchmark. - Enter namespace when reading build-id in 'perf inject'. - Do not load map/dso when injecting build-id speeding up the 'perf inject' process. - Add --buildid-all option to avoid processing all samples, just the mmap metadata events. - Add feature test to check if libbfd has buildid support - Add 'perf test' entry for PE binary format support. - Fix typos in power8 PMU vendor events JSON files. - Hide libtraceevent non API functions. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Test results: The first ones are container based builds of tools/perf with and without libelf support. Where clang is available, it is also used to build perf with/without libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang when clang and its devel libraries are installed. The objtool and samples/bpf/ builds are disabled now that I'm switching from using the sources in a local volume to fetching them from a http server to build it inside the container, to make it easier to build in a container cluster. Those will come back later. Several are cross builds, the ones with -x-ARCH and the android one, and those may not have all the features built, due to lack of multi-arch devel packages, available and being used so far on just a few, like debian:experimental-x-{arm64,mipsel}. The 'perf test' one will perform a variety of tests exercising tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands with a variety of command line event specifications to then intercept the sys_perf_event syscall to check that the perf_event_attr fields are set up as expected, among a variety of other unit tests. Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/ with a variety of feature sets, exercising the build with an incomplete set of features as well as with a complete one. It is planned to have it run on each of the containers mentioned above, using some container orchestration infrastructure. Get in contact if interested in helping having this in place. $ grep "model name" -m1 /proc/cpuinfo model name: AMD Ryzen 9 3900X 12-Core Processor $ export

cgroup improvements for 'perf stat', allowing for compact specification of events and cgroups in the command line. - Support per thread topdown metrics in 'perf stat'. - Support sample-read topdown metric group in 'perf record' - Show start of latency in addition to its start in 'perf sched latency'. - Add min, max to 'perf script' futex-contention output, in addition to avg. - Allow usage of 'perf_event_attr->exclusive' attribute via the new ':e' event modifier. - Add 'snapshot' command to 'perf record --control', using it with Intel PT. - Support FIFO file names as alternative options to 'perf record --control'. - Introduce branch history "streams", to compare 'perf record' runs with 'perf diff' based on branch records and report hot streams. - Support PE executable symbol tables using libbfd, to profile, for instance, wine binaries. - Add filter support for option 'perf ftrace -F/--funcs'. - Allow configuring the 'disassembler_style' 'perf annotate' knob via 'perf config' - Update CascadelakeX and SkylakeX JSON vendor events files. - Add support for parsing perchip/percore JSON vendor events. - Add power9 hv_24x7 core level metric events. - Add L2 prefetch, ITLB instruction fetch hits JSON events for AMD zen1. - Enable Family 19h users by matching Zen2 AMD vendor events. - Use debuginfod in 'perf probe' when required debug files not found locally. - Display negative tid in non-sample events in 'perf script'. - Make GTK2 support opt-in - Add build test with GTK+ - Add missing -lzstd to the fast path feature detection - Add scripts to auto generate 'mmap', 'mremap' string<->id tables for use in 'perf trace'. - Show python test script in verbose mode. - Fix uncore metric expressions - Msan uninitialized use fixes. - Use condition variables in 'perf bench numa' - Autodetect python3 binary in systems without python2. - Support md5 build ids in addition to sha1. - Add build id 'perf test' regression test. - Fix printable strings in python3 scripts. - Fix off by ones in 'perf trace' in arches using libaudit. - Fix JSON event code for events referencing std arch events. - Introduce 'perf test' shell script for Arm CoreSight testing. - Add rdtsc() for Arm64 for used in the PERF_RECORD_TIME_CONV metadata event and in 'perf test tsc'. - 'perf c2c' improvements: Add "RMT Load Hit" metric, "Total Stores", fixes and documentation update. - Fix usage of reloc_sym in 'perf probe' when using both kallsyms and debuginfo files. - Do not print 'Metric Groups:' unnecessarily in 'perf list' - Refcounting fixes in the event parsing code. - Add expand cgroup event 'perf test' entry. - Fix out of bounds CPU map access when handling armv8_pmu events in 'perf stat'. - Add build-id injection 'perf bench' benchmark. - Enter namespace when reading build-id in 'perf inject'. - Do not load map/dso when injecting build-id speeding up the 'perf inject' process. - Add --buildid-all option to avoid processing all samples, just the mmap metadata events. - Add feature test to check if libbfd has buildid support - Add 'perf test' entry for PE binary format support. - Fix typos in power8 PMU vendor events JSON files. - Hide libtraceevent non API functions. * tag 'perf-tools-for-v5.10-2020-10-15' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (113 commits) perf c2c: Update documentation for metrics reorganization perf c2c: Add metrics "RMT Load Hit" perf c2c: Correct LLC load hit metrics perf c2c: Change header for LLC local hit perf c2c: Use more explicit headers for HITM perf c2c: Change header from "LLC Load Hitm" to "Load Hitm" perf c2c: Organize metrics based on memory hierarchy perf c2c: Display "Total Stores" as a standalone metrics perf c2c: Display the total numbers continuously perf bench: Use condition variables in numa. perf jevents: Fix event code for events referencing std arch events perf diff: Support hot streams comparison perf streams: Report hot streams perf streams: Calculate the sum of total streams hits perf streams: Link stream pair perf streams: Compare two streams perf streams: Get the evsel_streams by evsel_idx perf streams: Introduce branch history "streams" perf intel-pt: Improve PT documentation slightly perf tools: Add support for exclusive groups/events ...
