It is a regression that I have introduce with universal plane. I have fix it and refresh v8 branch.
I have map CRTC on hardware mixers IP. I could have one or two mixers, its depends of the chipset and I use one graphic input (GDP) per mixer as primary plane. Other GPD are used as overlay planes. Some version of the display IP have one hardware cursor which could be used only with the first mixer.
I haven't push yet the code to support the cursor, I would like to do it when the current patches will have been accepted and merge upstream.

hmm, Benjamin probably should try modetest w/ -v arg.. it does look a bit like something is missing here..

first read-through, but I have no clue about the sti hw. And in any case those pointers really only matter for backwards compat with existing pageflip and cursor ioctls, so doesn't really matter too much.
Anyway didn't spot anything else which would need to be upgrade to never kms interfaces, so ack from my side for that. Only looked at that since right now I'm refreshing drm docs in those areas ;-)
