perf test sigtrap: Add basic stress test for sigtrap handling

2021-12-08T01:18:23+00:00

Add basic stress test for sigtrap handling as a perf tool built-in test. This allows sanity checking the basic sigtrap functionality from within the perf tool. Committer notes: Reported that !root was getting -EPERM, applied a fixup from Marco to set .exclude_{hv,kernel} that made it work.

perf test: Remove skip_if_fail

2021-11-13T21:11:50+00:00

Remove optionality, always run tests in a suite even if one fails. This brings perf's test more inline with kunit that lacks this notion.

perf test: Remove is_supported function

2021-11-13T21:11:50+00:00

All tests now return TEST_SKIP if not supported. Removing this function brings perf's test_suite struct more inline with kunit.

perf test: BP tests, remove is_supported use

2021-11-13T21:11:50+00:00

Migrate the is_supported functionality to returning TEST_SKIP. Motivation is kunit has no is_supported function.

perf test: Add test case struct.

2021-11-13T13:32:26+00:00

Add a test case struct mirroring the 'struct kunit_case'. Use the struct with the DEFINE_SUITE macro, where the single test is turned into a test case. Update the helpers in builtin-test to handle test cases.
