[RFC 3/3] perf/tools/pmu_events/powerpc: Add hv_24x7 core level metric events

From: Kajol Jain
Date: Thu Jun 25 2020 - 07:48:10 EST


This patch adds hv_24x7 core level events in nest_metric.json file
and also add PerChip/PerCore field in metric events.

Result:

power9 platform:

command:# ./perf stat --metric-only -M PowerBUS_Frequency -C 0 -I 1000
1.000070601 1.9 2.0
2.000253881 2.0 1.9
3.000364810 2.0 2.0
