traced_perf is required for using e.g. callstack_sampling, see https://perfetto.dev/docs/getting-started/cpu-profiling Tested on qemu: Starting perfetto using a configuration which uses `callstack_sampling` starts traced_perf as a side-effect when perfetto is compiled with clang: ``` root@qemux86-64:~# tracebox --txt -c /tmp/config.pbtxt -o /tmp/perfetto-trace.pb & root@qemux86-64:~# ps -eo pid,cmd | grep tracebox 529 tracebox --txt -c /tmp/config.pbtxt -o /tmp/perfetto-trace.pb 530 /usr/bin/tracebox traced 533 /usr/bin/tracebox traced_probes --reset-ftrace 536 /usr/bin/tracebox traced_perf ``` Signed-off-by: Etienne Cordonnier <ecordonnier@snap.com> Signed-off-by: Khem Raj <raj.khem@gmail.com> |
