The usual approach we follow in i915 for things that affect more than one plane is is to collect that state into the crtc state. That way we get to remember it for the planes that are not part of the current commit. And when we have state that affects more than one crtc that again get collected up one level up in what we call global state (basically drm_private_obj with less heavy handed locking scheme).
I'm confused. Don't we always have the full state available? Why do you need to store state into custom crtc-state?
Here we are interested in the x, y and z positions of all the planes on a crtc. Creating a custom state object and duplicating that information there seems a bit silly, as surely that information is tracked by DRM?
Or what am I missing here... Tomi -- Texas Instruments Finland Oy, Porkkalankatu 22, 00180 Helsinki. Y-tunnus/Business ID: 0615521-4.
