Yeah, I think TYPE_PLANE is really confusing, and too much aimied at your
vmwgfx special case (where the virtual hw requires that this all lines up
properly). I think providing FB coordinates, and doing the vmwgfx-specific
remapping in vmwgfx code is better.
And someone else can then figure out how to handle CRTC overall damage for
physical devices. As mentioned by me (and Rob Clark too), most hw only
allows for 1 (or maybe 2) overall damage rects, so that helper would need
to combine all the damge rects into 1. Plus take stuff like
gamma/ctm/alpha into account too. Better we leave that to someone who
