Intel Driver Update Improves Old Hardware Support

Chris Wilson has continued with the xf86-video-intel 2.20.x point releases.

The highlight of the latest xf86-video-intel 2.20.14 point release is improving the Intel "Gen4" support, which spans Intel hardware from the i965G chipset through the GM45 chipset.

There's been an old bug in the shader assembly that was fixed meanwhile Chris Wilson went through and reviewed the Gen4 back-end and made some improvements such as for very large buffers, the Gen4/5 opacity shader, queuing a pending vblank request after a flip completion, avoiding migrating an uninitialized pixmap, and improved handling of texture fallbacks for i830/i845 hardware.

Chris Wilson personally made 45 driver changes to this release while Eric Anholt squeezed in five. Most of the work done by Wilson was on SNA, the Sandy Bridge New Acceleration Architecture.

The release announcement for xf86-video-intel 2.20.14 can be found on xorg.
