[PATCH v2 21/43] perf test x86 hybrid: Update test expectations

Ian Rogers
2023-04-28T07:42:55Z

Don't assume evlist order. Switch to a loop rather than depend on
evlist order for raw events test.

Update hybrid event expectations. Previous values were based on
parsing legacy hardware events from sysfs, update to the correct PMU
specific legacy values.
