Namhyung Kim 6fda2405f4 perf lock: Implement cpu and task filters for BPF ... Add -a/--all-cpus and -C/--cpu options for cpu filtering. Also -p/--pid and --tid options are added for task filtering. The short -t option is taken for --threads already. Tracking the command line workload is possible as well. $ sudo perf lock contention -a -b sleep 1 Signed-off-by: Namhyung Kim <namhyung@kernel.org> Cc: Blake Jones <blakejones@google.com> Cc: Boqun Feng <boqun.feng@gmail.com> Cc: Davidlohr Bueso <dave@stgolabs.net> Cc: Ian Rogers <irogers@google.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Waiman Long <longman@redhat.com> Cc: Will Deacon <will@kernel.org> Link: https://lore.kernel.org/r/20220729200756.666106-4-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2022-08-01 09:28:51 -03:00
