[0/5] Refactor to expand subslice mask

Message

Summers, Stuart May 3, 2019, 9:30 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
v4: rebase
v5: fix header test
v6: address review comments from Jari
    address minor checkpatch warning in existing code
    use eu_stride for EU div-by-8
v7: another rebase
v8: address review comments from Tvrtko and Daniele

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: Refactor sseu helper functions
  drm/i915: Expand subslice mask
