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
