perf test: Tag parallel failing shell tests with "(exclusive)"Some shell tests compete for resources and so can't run with othertests, tag such tests.

3662f82f - perf test: Speed up some tests using perf list

Wed, 16 Oct 2024 06:56:54 +0000

perf test: Speed up some tests using perf listOn my system, perf list is very slow to print the whole events. I thinkthere's a performance issue in SDT and uprobes event listing. I noticedthis issue while running perf test on x86 but it takes long to checksome CoreSight event which should be skipped quickly.Anyway, some test uses perf list to check whether the required event isavailable before running the test. The perf list command can take anargument to specify event class or (glob) pattern. But glob pattern isonly to suppress output for unmatched ones after checking all events.In this case, specifying event class is better to reduce the number ofevents it checks and to avoid buggy subsystems entirely.No functional changes intended.Reviewed-by: James Clark Reviewed-by: Ian Rogers Cc: German Gomez Cc: Carsten Haitzler Cc: Leo Yan Link: https://lore.kernel.org/r/20241016065654.269994-1-namhyung@kernel.orgSigned-off-by: Namhyung Kim List of files: /linux-6.15/tools/perf/tests/shell/test_arm_spe.sh

perf test: Add ARM SPE system wide testIn the past it had a problem not setting the pid/tid on the samplecorrectly when system-wide mode is used.
