[Intel-gfx] [PATCH v4 i-g-t 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.

v3:
 * A bunch of review feedback implemented.

v4:
 * Tests for semaphore waits and event waits.
 * Review feedabck.
 * RAPL PMU for intel-gpu-overlay.
