[Intel-gfx] [PATCH v4 00/15] Enable OA unit for Gen 8 and 9 in i915 perf

[Robert Bragg]

Updates based on latest review feedback from Matthew and Lionel and includes an
update to the TestOa register config for SKL GT2 compared the last series (based
on the latest XML files from VPG)

Although the _[SUB]SLICE_MASK GETPARM patches were reviewed, it's worth
mentioning there was a TODO comment in the last patches about rebasing the
parameter ID before upstreaming which is removed now, and there's a minimal
comment for what the new parameters are, consistent with other more recently
added parameters. Conveniently the actual IDs didn't need rebasing so there's
no last moment uapi change for gputop, mesa and igt.

The series is longer just because I've included the gen7 prep patches (already
reviewed) that I haven't landed yet but the gen8+ bits depend on.

Regards,
- Robert
