[0/5] Refactor to expand subslice mask

Message

Summers, Stuart April 25, 2019, 10:24 p.m. UTC

This patch series contains a few code clean-up patches, followed
by a patch which changes the storage of the subslice mask to better
match the userspace access through the I915_QUERY_TOPOLOGY_INFO
ioctl. The index into the subslice_mask array is then calculated:
  slice * subslice stride + subslice index / 8

v2: fix i915_pm_sseu test failure
v3: no changes to patches in the series, just resending to pick up
    in CI correctly

Stuart Summers (5):
  drm/i915: Use local variable for SSEU info in GETPARAM ioctl
  drm/i915: Add macro for SSEU stride calculation
  drm/i915: Move calculation of subslices per slice to new function
  drm/i915: Move sseu helper functions to intel_sseu.h
  drm/i915: Expand subslice mask
