perf test: Adjust case of test metrics

2022-10-06T11:03:52Z

Icelake and later architectures have slots events and SLOTS metrics meaning case sensitivity is important. Make the test metrics case agree with the name of the metrics.

perf test: Add pmu-events test for aliases with hyphens

2022-01-22T20:21:29Z

Add a test for aliases with hyphens in the name to ensure that the pmu-events tables are as expects. There should be no reason why these sort of aliases would be treated differently, but no harm in checking.

perf vendor-events: Fix all remaining invalid JSON files

2021-10-08T18:59:21Z

Remove trailing commas. A later commit will make the parser more strict and these will not be valid anymore.

perf jevents: Add test for arch std events

2020-11-04T12:42:41Z

Recently there was an undetected breakage for std arch event support. Add support in "PMU events" testcase to detect such breakages. For this, the "test" arch needs has support added to process std arch events. And a test event is added for the test, ifself. Also add a few code comments to help understand the code a bit better.
