[PATCH 0/3] drm/i915: Skylake plane update/disable unifications [v4]

[Juha-Pekka Heikkila]

[v4] rebase

[v3] Took into account fbc adjusted y/x for primary plane (ville syrjälä)

[v2] Fixed missed references which were brough on rebase.

You fail to update the skl function, so this won't build. Please make
sure each step in the series builds (and ideally also works). That way
people can actually bisect through the series.

[PATCH 2/3] drm/i915: Unify skylake plane update

[Juha-Pekka Heikkila]

Don't handle skylake primary plane separately as it is similar
plane as the others.

Please split this into two patches. First one should nuke the
adjusted_x/y from the crtc, the second should do the skl function
unification.

As I said earlier, we'll want to get rid if this crtc->base.y thing as
well. I think it's actually semi broken at the moment since we seem to
be stuffing the unclipped coordinate in there. It should really be
the clipped one (ie. plane_state->src.y1 >> 16). So we'll want to put
that (or potentially the whole fence_offset) into the fbc cache as well.
I guess we could do that part as a separate patch though.

While I was looking at the fbc code it occurred to me that it's doing
way too much checking in the can_activate() function. Most of the checks
it's doing there we could have done already when we had the plane/crtc
states around. So I think we should pre-compute more of the answer to the 
"can this plane/crtc do fbc?" question. It might allow us to nuke some
stuff from the fbc state cache as well.

[PATCH 3/3] drm/i915: Unify skylake plane disable

[Juha-Pekka Heikkila]

Don't handle skylake primary plane separately as it is similar
plane as the others.
