[PATCH v3 0/4] modesetting: Add RandR-based shadow buffer support

[Jason Ekstrand]

This is my third attempt at properly adding RandR shadow support.  As per
my discussion with keith on my previous try, I have reworked it to be
per-crtc and to not touch the old shadow code.  Hopefully, the two will
nicely live side-by-side for the time being.  Eventually, we may be able to
use RandR shadow support for everything in the future, but we don't do that
yet.

Jason Ekstrand (4):
  modesetting: Refactor drmmode_glamor_new_screen_pixmap
  modesetting: Add drmmode_bo_has_bo and drmmode_bo_map helper function
  modesetting: Add support for using RandR shadow buffers
  modesetting: Return the crtc for a drawable even if it's rotated
