Release 2.21.4 (2013-03-11)
==========================More bugs, more fixes, more releases. A minor new
feature being introduced
is the runtime detection of CPU instructions sets along with specialised
paths to take advantage of the available CPU.
* Honour LinearFramebuffer for clumsy PowerXpress integration
* Disable read-read optimisations of mappings whilst the root
cause of a corruption issue remains elusive.
https://bugs.freedesktop.org/show_bug.cgi?id=61628
* Disable 8-bpp framebuffers in UXA as the regressions therein
remain unfixed.
* Restart vertex checks after lock contention
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1124576
* Handle Screen Pixmap recreation whilst exported via PRIME.
* Correct application of scale factors to video source offsets.
https://bugs.freedesktop.org/show_bug.cgi?id=61610
* Chain up CloseScreen so that resources are actually freed across regen
https://bugs.freedesktop.org/show_bug.cgi?id=56608
* Fix Haswell CRW PCI-IDs
* Handle batch submission failure during DRI copies
https://bugs.freedesktop.org/show_bug.cgi?id=61708
* Probe for kernel support of requested Screen depth
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1135403
* Correct GPU limits for early gen2 and gen3 architectures and prevent
an infinite recursion for particular image sizes.
