From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> Fifth spin of the i915 PMU series. Just some small cleanups across a few patches and a rebase to latest drm-tip. Patches 1-2 are small refactors to make the following work easier. Patch 3 is the main bit. Patch 4 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 5-7 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. And finally patch 8 is an additional optimisation which hides the whole cost of the software engine busyness tracking behind a single nop instruction in the off case.
