Intel's Eric Anholt has been working on pulling
Render improvements for the
Intel 965 IGP chipset out of the intel-batchbuffer branch of the
xf86-video-intel driver and pushing them into the mainline driver. These mainline Render improvements aren't yet there, but Eric has the code right now in his personal Intel git repository on
FreeDesktop.org. Stopping this work right now are color correctness issues.
If you're interested in checking out these EXA/Render improvements for the 965 IGP, check out
his blog entry and his personal git repository. Meanwhile, what is (and has been, but a constant work in progress) in the intel-batchbuffer branch is
TTM memory management, improved EXA performance, and support for
DRI2.
