From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> Review feedback so far, plus re-organisation of the series to drop potentially not so interesting metrics into separate patches, at the end of the series. Patche 1 is a small refactor to make the following work easier. Patch 2 is the main bit. Patch 3 is a small optimisation on top, to only run the sampling timer when it is required. (Depending on GPU awake status and active PMU counters.) Patches 4-7 add software engine busyness tracking, which is then used from the PMU in patch 7. This allows more efficient and more accurate engine busyness metric. Patches 8-10 add the RC6 and interrupt count metric.
