perf test: Use 3 digits for test numbering now we can have more tests

2021-12-21T20:52:27Z

This is in preparation for adding more tests that will need the test number to be 3 digts so they align nicely in the output.

perf bench: Use unbuffered output when pipe/tee'ing to a file

2021-12-16T15:18:11Z

The output of 'perf bench' gets buffered when I pipe it to a file or to tee, in such a way that I can see it only at the end. E.g. $ perf bench internals synthesize -t < output comes out fine after each test run > $ perf bench internals synthesize -t | tee file.txt < output comes out only at the end of all tests > This patch resolves this issue for 'bench' and 'test' subcommands. See, also: $ perf bench mem all | tee file.txt $ perf bench sched all | tee file.txt $ perf bench internals all -t | tee file.txt $ perf bench internals all | tee file.txt Committer testing: It really gets staggered, i.e. outputs in bursts, when the buffer fills up and has to be drained to make up space for more output.

perf test sigtrap: Add basic stress test for sigtrap handling

2021-12-08T01:18:23Z

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

2021-11-13T21:11:50Z

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

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

perf test: Add test case struct.

2021-11-13T13:32:26Z

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.
