The 25th edition of the Nouveau Companion is out a bit late, but it's filled with interesting content on the latest work going into this open-source NVIDIA driver. The topics making up this issue include the DMA notifier, the TTM memory manager, continued work with X-Video and XvMC, renouveau splitting, PowerPC work, and DRM 0.0.10. After a heated discussion, the decision was made to move to the TTM memory manager with the Nouveau driver as David Airlie would only like one memory manager in the DRM tree. The X-Video performance on many NVIDIA GeForce graphics cards should also be improved in this release. Check out Nouveau Companion 25 on the Nouveau Wiki
As something to look out for in the future, new editions of the Nouveau Companion will likely be published on Phoronix in its entirely in advance of it becoming available on the FreeDesktop.org Wiki by one to three days.
