EXA Improvements (Almost) For Intel 965
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.
