[v3,0/7] drm/i915: Vulkan performance query support

Message

Hi all,

This is a pretty big update following v2.

The first big change is to drop the HW arbitration usage in favor of a
software mechanism using a special priority in the scheduler.

The second is a rework of the uAPI. Since we have a couple of execbuf
uAPI changes for this series (VK_INTEL_performance_query) & timeline
semaphores, we can come up with a more generic mechanism that could be
extended in the future. Rather than reusing partially deprecated
fields.

Unfortunately (or not!) that requires timeline semaphores to be added
to the series because we need to use cliprects_ptr that is already
used by FENCE_ARRAY.

Cheers,
