[Qemu-devel] [PATCH 0/9] hw/display: make display updates thread safe, part 1

[Gerd Hoffmann]

  Hi,

Ok, 2.10 is open, lets start tackling the display update race
conditions.  This series adds the helper functions used to receive
a dirty bitmap snapshot, which is used by the display adapters then.
Also a bunch of display adapters are converted to use those helpers.

Changes from previous version:  Fixed one vga patch.  Left out are the
sparc adapters for now (Mark Cave-Ayland is busy cleaning them up and
fixing them).  Also left out the patch dropping the temporary
workaround, that obviously has to wait until all display adapters are
switched over.

please review,
  Gerd
