Yesterday in the
Phoronix Forums it was asked
what's up with the Nouveau and RadeonHD drivers, which happens to be a very good question. The last time we had much to report on with regard to RadeonHD, the driver created by Novell for use with ATI R500+ GPUs, was back in July when it received
better power management capabilities. The last time we had much to report on with Nouveau, the community-spawned driver to provide an open-source 2D/3D driver for NVIDIA hardware, was back in April when talking about
using the Nouveau driver in Ubuntu 9.04. The last time, however, that there was a Nouveau Companion update was
back in March. While news and major advancements with these two open-source drivers have been lacking lately, both projects are still surely in existence.
The RadeonHD driver continues to see new
code commits, albeit at a slower rate than in the past after
losing a developer, and there hasn't been as much exciting work going into xf86-video-radeonhd when compared against the xf86-video-ati driver. Since the start of September to date there have been 36 commits to the RadeonHD driver, but nearly all of them have been to address bug-fixes, quirks, and the like. The RadeonHD developers are currently preparing for a new release, xf86-video-radeonhd 1.2.6, which should be out in a matter of days. The current stable release of the RadeonHD driver came
back in April.
The Nouveau driver also continues to receive new work with its
xf86-video-nouveau DDX and
Nouveau DRM as well as to its
Nouveau Gallium3D driver in Mesa. Unfortunately though there hasn't been a lot of major advancements forward lately and the Nouveau project has yet to put out a stable release. Pushing the Nouveau DRM code into the
Linux 2.6.32 kernel to provide NVIDIA kernel mode-setting support did not happen and it's not clear when this will happen to at least have a stable 2D driver release. The 3D driver via
Gallium3D is still a ways out.
There is a
TODO list for Nouveau along with the
current feature matrix. This feature matrix shows that basic 2D support along with X-Video playback acceleration is working for all NVIDIA cards from the NV04 ASIC up through the latest NV50 GPUs, but X Render acceleration is still being tackled for NV50. Nearly all of the 3D capabilities for the different generations of NVIDIA hardware have yet to be implemented. Likewise, features like RandR 1.2, NouveauFB, TV-Out, power-savings, and even dual-link DVI still need to be implemented for much of NVIDIA's hardware.
It's unfortunate that the RadeonHD and Nouveau projects are not accelerating as fast as some would like, but feel free to give them a hand if you wish as neither project would resist new development support. Hopefully in the near future we will have better news to report from both projects.
