[PATCH 0/2] perf vendor events arm64: Fix Tegra410 Olympus PMU events

Posted by Besar Wicaksono 1 month, 2 weeks ago

Fix two issues in the NVIDIA Tegra410 Olympus PMU event definitions:

  - Correct the swapped MetricGroup assignments for the L1 data and
    instruction prefetcher metrics.
  - Correct the name and description of implementation-defined event
    0x0197.

Patch 1 resends the original patch from Saurav:
