[PATCH 0/7] Add PMU support for single engine busyness

[Riana Tauro]

The first 3 patches of the series are taken from
https://patchwork.freedesktop.org/series/139121/. They are added
only for compilation and does not require review.

This series adds support for single engine busyness.

PMU provides two counters (<engine>-busy-ticks-gt<n>,
<engine>-total-ticks-gt<n>) to calculate engine busyness. When querying
engine busyness, user must group these 2 counters using the perf_event
group mechanism to ensure both counters are sampled together.

To list engine busyness counters use the following

./perf list
  xe_0000_03_00.0/bcs0-busy-ticks-gt0/               [Kernel PMU event]
  xe_0000_03_00.0/bcs0-total-ticks-gt0/              [Kernel PMU event]
  xe_0000_03_00.0/ccs0-busy-ticks-gt0/               [Kernel PMU event]
  xe_0000_03_00.0/ccs0-total-ticks-gt0/              [Kernel PMU event]

Engine busyness can then be calculated as below
busyness % = (engine active ticks/total ticks) * 100
