| |
If all (non-dummy) evsel have exclude_user, system_wide sideband is not needed. Add this test scenario.
Test result:
# ./perf test list 2>&1 | grep 'Setup struct perf_event_attr' 17: Setup struct perf_event_attr # ./perf test 17 -v 17: Setup struct perf_event_attr : --- start --- test child forked, pid 720198 <SNIP> running './tests/attr/test-record-C0-all-kernel' <SNIP> test child finished with 0 ---- end ---- Setup struct perf_event_attr: Ok
