[Intel-gfx] [PATCH 0/3] 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.

This series was split into 2. The first part is merged. This part
enables interrupts.

Regards,
Umesh
