Daniel and Ville don't want to expose 2 DRM planes and would rather expose a CURSOR plane that has all the usual plane properties, and that's a blocker for lifting the prelimary_hw_support flag. Unfortunately noone has had the time to finish this yet, but lifting the prelimary_hw_support flag is long overdue. As an intermediate solution we can merely not expose the top most plane Cc: Imre Deak Signed-off-by: Damien Lespiau Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
