[Intel-gfx] [PATCH v3 0/8] drm/i915: GTT remapping for display

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Another gtt remapping posting.

Changes since the last time:
- split out the plane stride check function (already in)
- use add_overflows() (after massaging it a bit)
- include some selftests for the remapped/rotated vmas
- reduce the max fb size to 16kx16k on gen7+ due to mesa+glamor
  and keep it unchanged at 8kx8k on gen4+ for the same reason

Ville Syrjälä (8):
  drm/i915: Make sure fb gtt offsets stay within 32bits
  drm/i915: Decouple SKL stride units from intel_fb_stride_alignment()
  drm/i915: Add a new "remapped" gtt_view
  drm/i915/selftests: Add mock selftest for remapped vmas
  drm/i915/selftests: Add live vma selftest
  drm/i915: Overcome display engine stride limits via GTT remapping
  drm/i915: Bump gen4+ fb stride limit to 256KiB
  drm/i915: Bump gen7+ fb size limits to 16kx16k
