[PATCH v2 00/18] drm/qxl: ttm fixes, cleanups, allocation tweaks, multihead, fbdev

[Gerd Hoffmann]

So, here is the all-in-one package of all my qxl changes.  Some of these
changes have been on the list before, some not.  Summary:

 (1) A collection of misc ttm bugfixes and cleanups.

 (2) Move some allocations from VRAM to PRIV domain, to reduce VRAM
     memory pressure.  Should help especially with wayland, which uses
     dumb gem buffers.

 (3) Extend the shadow bo logic to handle multihead setups with dumb
     buffers.  Helps wayland too.

 (4) Switch qxl over to the generic fbdev emulation.

cheers,
  Gerd
