[Intel-gfx] [RFC PATCH 0/4] drm/i915: enable userspace to program slice/subslice programming

[Lionel Landwerlin]

Hi all,

This is a respin of a series from Chris. Actually got around testing
it a bit. The main reason for this feature is to allow media workloads
to tweak the number of slices powered on. It seems to have significant
performance gains.

Cheers,

Chris Wilson (4):
  drm/i915: Record both min/max eu_per_subslice in sseu_dev_info
  drm/i915: Program RPCS for Broadwell
  drm/i915: Record the sseu configuration per-context & engine
  drm/i915: Expose RPCS (SSEU) configuration to userspace
