[kvm-unit-tests Patch 0/5] Fix PMU test failures on Sapphire Rapids

[Dapeng Mi]

When running pmu test on Intel Sapphire Rapids, we found several
failures are encountered, such as "llc misses" failure, "all counters"
failure and "fixed counter 3" failure.

Intel Sapphire Rapids introduces new fixed counter 3, total PMU counters
including GP and fixed counters increase to 12 and also optimizes cache
subsystem. All these changes make the original assumptions in pmu test
unavailable any more on Sapphire Rapids. Patches 2-4 fixes these
failures, patch 0 remove the duplicate code and patch 5 adds assert to
ensure predefine fixed events are matched with HW fixed counters.

Dapeng Mi (4):
  x86: pmu: Change the minimum value of llc_misses event to 0
  x86: pmu: Enlarge cnt array length to 64 in check_counters_many()
  x86: pmu: Support validation for Intel PMU fixed counter 3
  x86: pmu: Add asserts to warn inconsistent fixed events and counters

Xiong Zhang (1):
  x86: pmu: Remove duplicate code in pmu_init()
