[Intel-gfx] [PATCH v16 00/17] Enable OA unit for Gen 8 and 9 in i915 perf

[Lionel Landwerlin]

Hi,

Here is another update on this series. There has been some discussion
about handling the dynamic slice/subslice shutdown cases. In most
cases this isn't actually interesting. Indeed most 3D workloads will
want all of the slices/subslices turned on. In that case it's
unfortunate to have to reload NOA configurations that won't change. To
that extent, patch 15 has been rework not to make this the default
behavior, but to let userspace decide what it wants to do.

This also means we need to bring back the old getparam patches (1 &
2), which give you the maximum number of slices/subslices the device
can have turned on.

In the case we want to monitor the entire system, userspace will want
to monitor slice/subslices configurations (patch 16). The C structures
related to that userspace API has changed slightly. Some of the recent
Cannonlake patches made me think we probably wanted not to share a
common structure for setting sseu configurations.

Finally patches 15, 16 have some fixes related to locking & off-by-one
errors.

Cheers,
