Hi all,

This series is enabling multiple context filtering for performance queries.

Our Iris driver uses 2 contexts to run 3D & compute commands with
synchronization between the 2 contexts.

Right now i915/perf only supports filtering/pinning a single context.

The Mesa change making use of this feature is now reviewed at :

Cheers,

  drm/i915/perf: break OA config buffer object in 2
  drm/i915/perf: stop using the kernel context
  drm/i915/perf: prepare driver to receive multiple ctx handles
  drm/i915/perf: enable filtering on multiple contexts
