[igt-dev] [PATCH i-g-t] i915/i915_pm_rc6_residency: Make ringbuffer rc6 fast

[igt-dev] [PATCH i-g-t] i915/i915_pm_rc6_residency: Make ringbuffer rc6 fast

[Chris Wilson]

The legacy ringbuffer submission lacks a fast soft-rc6
mechanism as we have no interrupt for an idle ring. As such
we are at the mercy of HW RC6... which is not quite as
precise as we need to pass this test. Oh well.

Since HW is not fast enough to minimise power draw, tell the driver to
park as soon as we know we are idle. One day, we hope for the driver to
discover a mechanism to do this for itself, for as this test shows that
can save us Watts!

Re: [Intel-gfx] [PATCH i-g-t] i915/i915_pm_rc6_residency: Make ringbuffer rc6 fast
