According to DRM documentation the only difference between PRIMARY and OVERLAY plane is that each CRTC must have PRIMARY plane and OVERLAY are optional.
Allow PRIMARY plane to have dimension different from full-screen.

So it applies to all the 4 patches you've sent, but this lacks some context.
There's a few questions that should be answered here: - Which situation is it fixing? - What tool / userspace stack is it fixing? - What happens with your fix? Do you set the plane at coordinates 0,0 (meaning you'll crop the top-lef corner), do you center it? If the plane is smaller than the CTRC size, what is set on the edges?
Thanks! Maxime
