Now that we subclass our request from struct fence, we start using the
common primitives more freely and so avoid hand-rolling routines already

With atomic plane states we are able to track an allocation right from

The generic atomic helper likes to skip a prepare_plane_fb() if it
decides that the plane->fb is unchanged. This is wrong for us for a
couple of reasons:

is untouched, we still have to flush any rendering prior to the

Since an fb may have multiple VMA (due to rotations etc), we need to

drm_atomic_state has a complicated single owner model that tracks the

The current meaning of whether an object has a GGTT vma is very

precious mappable aperture s

Currently when checking for fused off EUs we may ignore the EU count in
an enabled slice if there is any disabled slice preceding the enabled
one (with a lower slice ID). Perhaps this can't happen in reality, but
there is no reason to have this assumption built-in, the code is clearer
without it.

Storing the port enum in intel_encoder makes it convenient to know the
