[Intel-gfx] [PATCH 0/8] NV12 90/270 rotated GGTT mapping

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

First attempt at rotated GGTT mapping for the NV12 format.

It compiles and even does not crash on first use. But some parts are
probably too simplistic at the moment and need further polish.

Sending out early since Chandra needs this to complete his display
programming patches.

Depends on Chandra's NV12 patch series.

Tvrtko Ursulin (8):
  drm/i915: Remove duplicated intel_tile_height declaration
  drm/i915: Support planar formats in tile height calculations
  drm/i915: Remove pointless calculation in intel_rotate_fb_obj_pages
  drm/i915: Extract tiled geometry calculation into a helper function
  drm/i915: Support appending to the rotated pages mapping
  drm/i915: Support NV12 in rotated GGTT mapping
  drm/i915: Enable querying offset of UV plane with
    intel_plane_obj_offset
  drm/i915: Allow NV12 with 90/270 rotation
