Hi guys,
Please take a look, the example provided is too simple, using 'perf probe' to put probes in specific places in some workload to then get any other event close to the time the trigger hits comes to mind as well, using the signal was just to reuse the pre-existing logic and keep the patchkit small.
Its available at:
git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf/switch-output-event
Best regards,
- Arnaldo
Arnaldo Carvalho de Melo (7): perf record: Move sb_evlist to 'struct record' perf top: Move sb_evlist to 'struct perf_top' perf bpf: Decouple creating the evlist from adding the SB event perf bpf: Decouple creating the evlist from adding the SB event perf parse-events: Add parse_events_option() variant that creates evlist perf evlist: Allow reusing the side band thread for more purposes perf record: Introduce --switch-output-event
