Simon Ser	e2df5e73d0	List planes by allocation order ... Given a primary plane with zpos=0 and overlay planes with zpos 1 2, we want first to allocate the primary plane, then the furthest overlay plane, then the remaining one: 0 2 1.

Simon Ser	42db49c6fe	Guess zpos from plane type ... Many drivers don't expose the zpos plane property. We can guess it from the plane type though: primary, overlay, cursor. Except some drivers expose underlays too: underlays, primary, overlay, cursor. Underlay planes don't have a special type, they are just marked as overlays. To detect them, check whether their plane ID is less than the primary plane ID. References: https://github.com/emersion/libhwc/issues/3	2019-09-08 18:33:09 +03:00
Simon Ser	d90d7bdc36	Check plane is compatible with CRTC ... This allows us to rule out some potential solutions. Closes: https://github.com/emersion/libhwc/issues/2	2019-09-08 17:41:25 +03:00
Simon Ser	165d013b80	Change planes to be a linked list instead of an array ... We'll need this anyway when we allow users to choose which planes to give us. Let's not start building algorithms on top of arrays.	2019-09-08 15:26:50 +03:00
