[RFC 0/6] Use framebuffer modifiers for tiled display

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@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. Sending out early so
people can comment on the overall approach over the weekend.

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

  drm/i915: Use framebuffer tiling mode for display purposes
  drm/i915: Allow fb modifier to set framebuffer tiling
