[igt-dev] [PATCH i-g-t v2 0/3] add support for passing yuv writeback output format

[Abhinav Kumar]

MSM display pipeline has support for writeback to handle YUV formats.
Currently the kms_writeback supports hard-codes the writeback output
format to DRM_FORMAT_XRGB8888. This series makes the necessary changes
in the lib and kms_writeback to allow passing DRM YUV formats to
kms_writeback.

The default kms_writeback shall still use only DRM_FORMAT_XRGB8888.

Additional formats can be passed using the command line.

Sample usage of this would be:

./kms_writeback -f <name of the DRM YUV fmt from igt_fb>

changes in v2:
	- removed an unnecessary new line
	- fixed petri's email address

Abhinav Kumar (3):
  lib/igt_fb: add a helper to find drm_id from matching string
  lib/igt_fb: allow igt_fb_get_fnv1a_crc() to handle YUV formats
  tests/kms_writeback: allow writeback to output custom format
