[Intel-gfx] [PATCH i-g-t v2 0/7] IGT PMU support

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

1.
Fixes for intel-gpu-overlay to work on top of the proposed i915 PMU perf API.

2.
New test to exercise the same API.

3.
Update to gem_wsim and media-bench.pl to be able to use engine busyness via PMU
for making balancing decisions.

v2:
 * Added gem_wsim and media-bench.pl patches.
 * Comments and fixes for the perf_pmu test.

Tvrtko Ursulin (7):
  intel-gpu-overlay: Move local perf implementation to a library
  intel-gpu-overlay: Consolidate perf PMU access to library
  intel-gpu-overlay: Fix interrupts PMU readout
  intel-gpu-overlay: Catch-up to new i915 PMU
  tests/perf_pmu: Tests for i915 PMU API
  gem_wsim: Busy stats balancers
  media-bench.pl: Add busy balancers to the list
