For those following the xf86-video-ati
developments or use this open-source Radeon driver for their graphics card, you may want to check out the latest development code. Committed to its git branch today was a lot of new work from Alex Deucher, Dennis Kasprzyk, David Airlie, Egbert Eich, and Corbin Simpson.
There is now bi-cubic X-Video support for the Radeon R300 and R500 series GPUs, heavy optimizations in the video functions, and lots of code cleaning. The DRI, acceleration state, and CP (Command Processor) work has also been moved into their own code structures. This work came in the form of over two dozen code commits. The PowerPC build process for this ATI driver has also been fixed.
