[Intel-gfx] [PATCH v3 00/21] drm/i915: Handle fb->offsets[] and rewrite fb rotation handling to be more generic (v3)

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Another iteration of the fb offset stuff. Unfortunately this seems
to be one of those things that just keeps on growing when you're
not looking. But I'm hoping we're starting to approach the limit.

Changes from the last time [1]:
* split the chrome plane vma size fix from one of the other patches
* shuffling the bytes vs. pixels vs. tiles stuff around
* extracted a few more pieces of common code
* deal with fence vs. fb offset alignment better
* deal with SKL X-tile fail
* add preliminary NV12 AUX_DIST handling
* possible something else I've forgotten

I also have a few testcases lying around somewhere, but I'll need to
clean those up somewhat before I post them.

Entire lot (+ a few extras on top) available here:
