Earlier this month we shared that an experimental ATI DRI2 driver had emerged that offered Direct Rendering Infrastructure 2 support to the open-source ATI Linux driver with GEM and TTM bits. Today though Compiz is now working with this ATI DRI2 code.

The DRI2 support hasn't yet been merged to master for Mesa, DRM, and xf86-video-ati DDX driver, but it's a step closer. Jerome Glisse, Kristian Høgsberg, and David Airlie have been hacking away at the DRI2 support and today they have Compiz working partially on this newest code. Before getting too excited, there is still plenty of work ahead though and they have to migrate the older R100/200 driver to the new buffer object and command stream scheme and other changes on both the kernel and user space sides.

More information and the first screenshot of the DRI2-enabled Compiz can be found on Jerome's blog.
