[PATCH 1/2] powerpc/perf: Fix the threshold compare group constraint for power10

2022-05-05 Thread Kajol Jain
Thresh compare bits for a event is used to program thresh compare field in Monitor Mode Control Register A (MMCRA: 8-18 bits for power10). When scheduling events as a group, all events in that group should match value in threshold bits. Otherwise event open for the sibling events should fail. But i
