[Intel-gfx] [RFC v2 0/4] Use framebuffer modifiers for tiled display

[Tvrtko Ursulin]

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

Instead of using driver private set tiling ioctl, use the proposed addfb2 ioctl
extension to tell the driver about display buffer special formatting.

Lightly tested only with a hacked up igt/testdisplay.

v2:
   * Refactor the series to use fb->modifier[0] directly at call sites
     interested in tiling. (Daniel Vetter)

Rob Clark (1):
  RFC: drm: add support for tiled/compressed/etc modifier in addfb2

Tvrtko Ursulin (3):
  drm/i915: Add tiled framebuffer modifiers
  drm/i915: Use frame buffer modifiers for tiled display
  drm/i915: Announce support for framebuffer modifiers
