[Intel-gfx] [PATCH v5 00/11] Enable i915 perf stream for Haswell OA unit

[Robert Bragg]

This just rebases my i915 perf series on a recent drm-intel-nightly.

Considering now that this series has been reviewed a number of times by Chris,
and I think I've responded to his feedback: I wonder if this series is ready
to be added to drm-intel-nightly soon?

I think most of the effort for this series at the moment is just keeping up
with rebasing on nightlies.

Regards,
- Robert
