In addition to running 2D benchmarks, Intel's Chris Wilson has been busy pushing out point releases to the xf86-video-intel 2.20 series. Generally we don't see more than one or two point releases per cycle, but now we're already up to four.

In the past month since the release of xf86-video-intel 2.20.0 where SNA acceleration was taken mainstream, Chris Wilson of Intel's Open-Source Technology Center has released four DDX driver point releases in rapid succession.

Chris Wilson personally bundled 56 changes into this 2.20.4 driver update -- most of them concerning his prized "Sandy Bridge New Acceleration" architecture -- while there were a few commits by other developers. Prominent changes to this weekend's driver update is fixing potential errors from using a static code analyzer, an optimization in PolyFillRectangles, removing a UXA warning, fixing the validation of the X-Video pipe parameter, fixing 8x8 tiled-pattern fills, a compile failure in a certain condition, a Gen4 flush fix, and restoring preferred use of the RENDER ring for SNB+ DRI copies. In addition, this driver update features all of the new Intel Haswell variants.

The release announcement for xf86-video-intel 2.20.4 can be found on the X.Org mailing list.
