[PATCH 1/4] drm: Plumb modifiers through plane init
Ben Widawsky
ben at bwidawsk.net
Mon Jul 24 03:46:38 UTC 2017
This is the plumbing for supporting fb modifiers on planes. Modifiers
have already been introduced to some extent, but this series will extend
this to allow querying modifiers per plane. Based on this, the client to
enable optimal modifications for framebuffers.
This patch simply allows the DRM drivers to initialize their list of
supported modifiers upon initializing the plane.
v2: A minor addition from Daniel
v3:
* Updated commit message
* s/INVALID/DRM_FORMAT_MOD_INVALID (Liviu)
* Remove some excess newlines (Liviu)
* Update comment for > 64 modifiers (Liviu)
v4: Minor comment adjustments (Liviu)
v5: Some new platforms added due to rebase
v6: Add some missed plane inits (or maybe they're new - who knows at
this point) (Daniel)
