Recent revisions

31. By Julien Cristau on 2012-12-02

[ Timo Aaltonen ]
* New upstream bugfix release.
  - Fixes a long-standing bug in UXA pageflip code that was the
    source of many GPU hangs.

30. By Julien Danjou on 2012-08-26

* New upstream release.
  - Remove patch to support passing a builder string, merged upstream

29. By Julien Danjou on 2012-07-29

[ Maarten Lankhorst ]
* New upstream release:
  - First official release with sna
* Update to 2.20.1 point release:
  - A bug affecting gen4 handling of trapezoids was fixed, and CPU
    overhead reduced.
  - A fix for a bug causing corruption of a DRI2 unredirected client
    window that was resized whilst under a compositor.
  - Support for snoopable buffers on non-LLC architectures, coming to
    a future kernel. The aim to accelerate transfers between the CPU
    and the GPU, in particular to dramatically improve readback
    performance, and to further minimise clflushes.
  - Improvement to the composite performance on GT2 SandyBridge and
    IvyBridge devices, in particular the render copy is significantly
  - Improved handling for when acceleration is disabled, including
    permitting DRI2 to remain supported even if the X server believes
    the GPU wedged.
  - Shadow support was dropped from UXA as it was neither complete nor
    correct, use SNA instead.

[ Julien Danjou ]
* New upstream release (2.20.2)

28. By Cyril Brulebois on 2012-02-24

Enable SNA again, in experimental.

27. By Cyril Brulebois on 2012-02-04

* New upstream snapshot:
  - Merge from upstream master up to 24ece4a87e.

26. By Cyril Brulebois on 2012-01-16

* New upstream snapshot:
  - Merge from upstream master up to 5df7147b09.

25. By Cyril Brulebois on 2012-01-04

* New upstream snapshot:
  - Merge from upstream master up to 4119e68fb1.
* Implement a generate-snapshot rule to ease packaging snapshots.

24. By Cyril Brulebois on 2012-01-01

Build against Xserver 1.12 RC1 (Closes: #653914).

23. By Cyril Brulebois on 2012-01-01

* New upstream snapshot:
  - Merge from upstream master up to 770a953ff0.
* Enable SNA support, as suggested by upstream. It should be usable now
  and regression reports are welcome.
* Add patch to support passing a builder string:
  - 0001-Fix-build-failure-when-passing-with-builderstring.patch
* Pass a builder string, as done in the server.

22. By Cyril Brulebois on 2011-11-07

* New upstream release candidate:
  - A couple of critical stability fixes for SandyBridge and IvyBridge.
* Add a libpixman-1-dev build-dep: 0.16 is enough for a regular build,
  but enabling SNA would pull 0.23.
* Pass --with-builderstring. At the moment, it's only needed when
  enabling SNA (which we don't, following upstream's default), but let's
  do that right now.
* Add 0001-Fix-build-failure-when-passing-with-builderstring.patch
