HULK (2): perf stat: Increase perf_attr_map entries perf stat: Fix incorrect display of bperf when event count is 0 Ian Rogers (1): perf test bpf-counters: Add test for BPF event modifier Namhyung Kim (9): bpf: Allow bpf_get_current_ancestor_cgroup_id for tracing perf core: Factor out __perf_sw_event_sched perf core: Add PERF_COUNT_SW_CGROUP_SWITCHES event perf tools: Add 'cgroup-switches' software event perf tools: Add read_cgroup_id() function perf tools: Add cgroup_is_v2() helper perf bpf_counter: Move common functions to bpf_counter.h perf stat: Enable BPF counter with --for-each-cgroup perf stat: Fix BPF program section name Song Liu (13): bpftool: Add Makefile target bootstrap perf build: Support build BPF skeletons with perf perf stat: Enable counting events for BPF programs perf stat: Introduce 'bperf' to share hardware PMCs with BPF perf stat: Measure 't0' and 'ref_time' after enable_counters() perf util: Move bpf_perf definitions to a libperf header perf bpf: check perf_attr_map is compatible with the perf binary perf stat: Introduce config stat.bpf-counter-events perf stat: Introduce ':b' modifier perf stat: Introduce bpf_counter_ops->disable() perf bpf: Fix building perf with BUILD_BPF_SKEL=1 by default in more distros perf bpf_skel: Do not use typedef to avoid error on old clang perf test: Add a shell test for 'perf stat --bpf-counters' new option Tengda Wu (2): perf stat: Support inherit events during fork() for bperf perf test: Use sqrtloop workload to test bperf event Veronika Molnarova (1): perf test stat_bpf_counter.sh: Stabilize the test results include/linux/perf_event.h | 40 +- include/uapi/linux/perf_event.h | 1 + kernel/trace/bpf_trace.c | 2 + tools/bpf/bpftool/Makefile | 2 + tools/build/Makefile.feature | 4 +- tools/include/uapi/linux/perf_event.h | 1 + tools/lib/perf/include/perf/bpf_perf.h | 32 + tools/perf/Documentation/perf-stat.txt | 31 + tools/perf/Makefile.config | 9 + tools/perf/Makefile.perf | 65 +- tools/perf/builtin-stat.c | 110 ++- tools/perf/tests/shell/stat_bpf_counters.sh | 74 ++ tools/perf/util/Build | 2 + tools/perf/util/bpf_counter.c | 832 ++++++++++++++++++ tools/perf/util/bpf_counter.h | 131 +++ tools/perf/util/bpf_counter_cgroup.c | 307 +++++++ tools/perf/util/bpf_skel/.gitignore | 3 + tools/perf/util/bpf_skel/bperf_cgroup.bpf.c | 191 ++++ tools/perf/util/bpf_skel/bperf_follower.bpf.c | 162 ++++ tools/perf/util/bpf_skel/bperf_leader.bpf.c | 55 ++ tools/perf/util/bpf_skel/bperf_u.h | 19 + .../util/bpf_skel/bpf_prog_profiler.bpf.c | 93 ++ tools/perf/util/cgroup.c | 47 + tools/perf/util/cgroup.h | 13 + tools/perf/util/config.c | 4 + tools/perf/util/evlist.c | 4 + tools/perf/util/evsel.c | 27 + tools/perf/util/evsel.h | 32 + tools/perf/util/parse-events.c | 12 +- tools/perf/util/parse-events.l | 3 +- tools/perf/util/python.c | 27 + tools/perf/util/stat-display.c | 4 +- tools/perf/util/stat.c | 2 +- tools/perf/util/target.c | 34 +- tools/perf/util/target.h | 8 + tools/scripts/Makefile.include | 1 + 36 files changed, 2339 insertions(+), 45 deletions(-) create mode 100644 tools/lib/perf/include/perf/bpf_perf.h create mode 100755 tools/perf/tests/shell/stat_bpf_counters.sh create mode 100644 tools/perf/util/bpf_counter.c create mode 100644 tools/perf/util/bpf_counter.h create mode 100644 tools/perf/util/bpf_counter_cgroup.c create mode 100644 tools/perf/util/bpf_skel/.gitignore create mode 100644 tools/perf/util/bpf_skel/bperf_cgroup.bpf.c create mode 100644 tools/perf/util/bpf_skel/bperf_follower.bpf.c create mode 100644 tools/perf/util/bpf_skel/bperf_leader.bpf.c create mode 100644 tools/perf/util/bpf_skel/bperf_u.h create mode 100644 tools/perf/util/bpf_skel/bpf_prog_profiler.bpf.c -- 2.34.1
