[Intel-gfx] [PATCH 0/4] drm/i915/perf: add OA interrupt support

[Umesh Nerlige Ramappa]

Hi all,

This is a revival of an earlier patch series submitted by Lionel
Landwerlin - https://patchwork.freedesktop.org/series/54280/

The patches enable interrupt support for the perf OA unit in
i915, further details can be found in the orignal series linked
above.

v2: (Umesh)
- This series will split into 2. This revision will only support the addition of
  poll delay parameter to perf OA. If needed a future revision will incorporate
  interrupt support.

Regards,
Umesh
