selftests/powerpc/pmu: Add test for hardware cache events

Browse source

The testcase checks if the transalation of a generic hardware cache
event is done properly via perf interface. The hardware cache events has
type as PERF_TYPE_HW_CACHE and each event points to raw event code id.

Testcase checks different combination of cache level, cache event
operation type and cache event result type and verify for a given event
code, whether transalation matches with the current cache event mappings
via perf interface.
