We're trying to introduce support for writeback connectors, a way to
expose in DRM the hardware functionality from display engines that
allows to write back into memory the result of the DE's composition
of supported planes.

 - This is basically a v3 of the i-g-t tests, except I've now dropped
   all the changes that were trying to split the CRC functionality out
   of lib/igt_debugfs.c. v2 is here:
 - Added meson support for builting the kms_writeback test

Brian Starkey (6):
  lib/igt_kms: Add writeback support in lib/
  kms_writeback: Add initial writeback tests
  lib: Add function to hash a framebuffer
  kms_writeback: Add writeback-check-output
  lib/igt_kms: Add igt_output_clone_pipe for cloning
  kms_writeback: Add tests using a cloned output
