From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
Display engine on Skylake can scan out specially prepared frame buffers
rotated by 90 or 270 degrees.
This adds partial support for that - display programming patches are missing
from this initial posting because for now the only purpose is to see if people
now like the approach I have taken.
v2:
* Individual review comments.
* Main patch split into four smaller ones.
Tvrtko Ursulin (8):
drm: Pass in new and old plane state to prepare_fb and cleanup_fb
drm/i915/skl: Extract tile height code into a helper function
drm/i915: Use GGTT view when (un)pinning objects to planes
drm/i915: Pass in plane state when (un)pinning frame buffers
drm/i915: Helper function to determine GGTT view from plane state
drm/i915/skl: Support secondary (rotated) frame buffer mapping
drm/i915/skl: Query display address through a wrapper
drm/i915/skl: Take 90/270 rotation into account in watermark
calculations
