It uses task-clock and page-faults events with different filter expressions and check the perf script output $ sudo ./perf test filtering -vv 96: perf record sample filtering (by BPF) tests: --- start --- test child forked, pid 2804025 Checking BPF-filter privilege Basic bpf-filter test Basic bpf-filter test [Success] Failing bpf-filter test Error: task-clock event does not have PERF_SAMPLE_CPU Failing bpf-filter test [Success] Group bpf-filter test Error: task-clock event does not have PERF_SAMPLE_CPU Error: task-clock event does not have PERF_SAMPLE_CODE_PAGE_SIZE Group bpf-filter test [Success] Multiple bpf-filter test Multiple bpf-filter test [Success] ---- end(0) ---- 96: perf record sample filtering (by BPF) tests : Ok Signed-off-by: Namhyung Kim <namhyung@kernel.org> --- tools/perf/tests/shell/record_bpf_filter.sh | 34 +++++++++++++++++++++ 1 file changed, 34 insertions(+)
