Title:
[Bionic] Update ThunderX2 implementation defined pmu core events
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Bionic:
Fix Released
Bug description:
[IMPACT]
=======
The ARM architecture defines several events as part of the Performance
Monitor Unit (PMU) Extension. In addition, Cavium has added "implementation
defined" pmu core events, which Cavium deems most useful for analyzing
performance. Currently perf does not list these "implementation defined" events.
[FIX]
====
b9b77222d4ff perf vendor events arm64: Update ThunderX2 implementation
defined pmu core events
[TEST]
====
With the patch applied perf lists the additional PMU events.

[REGRESSION POTENTIAL]
======================
The patch is limited to ARM64, ThunderX2 PMU core definitions json file. No
regression potential for any kernel subsystems.
