perf tests record: Add basic uid filtering test

Based on the system-wide test with changes around how failure is handled as BPF permissions are a bigger issue than perf event paranoia. Signed-off-by: Ian Rogers Link: https://lore.kernel.org/r/20250604174545.2853620-6-irogers@google.com Signed-off-by: Namhyung Kim

perf test: Allow tolerance for leader sampling test

2025-05-15T15:55:51+00:00

There is a known issue that the leader sampling is inconsistent, since throttle only affect leader, not the slave. The detail is in [1]. To maintain test coverage, this patch sets a tolerance rate of 80% to accommodate the throttled samples and prevent test failures due to throttling.

On s390 the event instructions can not be used for recording. This event is only supported by perf stat. Change the event from instructions to cycles in subtest test_leader_sampling.

On s390 the event instructions can not be used for recording. This event is only supported by perf stat. Test that each event cycles and instructions supports sampling.

perf tests: Make leader sampling test work without branch event

2024-11-16T19:30:39+00:00

Arm a57 only has speculative branch events so this test fails there. The test doesn't depend on branch instructions so change it to instructions which is pretty much guaranteed to be everywhere. The test_branch_counter() test above already tests for the existence of the branches event and skips if its not present.

perf test: Tag parallel failing shell tests with "(exclusive)"

2024-10-28T16:32:58+00:00

Some shell tests compete for resources and so can't run with other tests, tag such tests. The "(exclusive)" stems from shared/exclusive to describe how the tests run as if holding a lock.
