While it will still be a while before the Linux 3.7 kernel is even released, the Linux 3.8 kernel may end up having better Nouveau driver re-clocking support for the common "NV50" NVIDIA GPU family.
With the significant DRM changes in the Linux 3.7 kernel there's something to enjoy out of all the major open-source graphics drivers. For Nouveau users, it's particularly exciting right now and there's more hope for the future.
There's some fan/thermal-related commits hitting the Nouveau driver's DRM repository.
According to a developer that began working on a PlayStation 3 graphics driver, which he's calling RSXGL, he reportedly got OpenGL 3.1 working from this Sony gaming console.
In continuation of NVIDIA Tegra With Open-Source Graphics Is Coming, here is the video that covers all of what's currently going on in the open-source Tegra world.
The Nouveau open-source driver is benefiting from sponsored X.Org EVoC work on the "Fermi Scripting Engine" to improve GeForce 400/500 series re-clocking.
Maarten Lankhorst talked at XDC2012 about the ongoing open-source work for supporting NVIDIA Optimus technology on the Linux desktop.
For those curious about the open-source Nouveau graphics driver performance on Ubuntu 12.10, here's a few benchmarks from a recent test release of the Quantal Quetzal with the reverse-engineered NVIDIA driver code.
The xf86-video-nouveau 1.0.2 driver was released today to take advantage of the new capabilities of X.Org Server 1.13.
The reverse-engineered open-source Nouveau driver has received its own FUC microcode implementation that frees it from having to use the binary microcode produced by the proprietary NVIDIA Linux graphics driver for the GeForce 600 "Kepler" graphics processors, but there's still problems ahead in supporting this latest-generation hardware.
While the RadeonSI Gallium3D driver could use a lot of help and the R600 Gallium3D driver still has an open TODO list, if you're a NVIDIA graphics hardware owner, the reverse-engineering Nouveau project could use your help.
Over the weekend there was the push by Red Hat's Ben Skeggs that effectively reworks/rewrites the Nouveau DRM kernel module for reverse-engineered open-source NVIDIA graphics under Linux.
After delivering some development statistics on the xf86-video-intel driver yesterday, today there's a look at the development activity surrounding xf86-video-nouveau. This is the X.Org driver for Nouveau, the reverse-engineered open-source NVIDIA driver.
Now that X.Org Server 1.13 RC1 is out there with the initial support for PRIME and other exciting features, dependent projects can also now move forward.
Gdev, the GPGPU run-time and resource management engines that provides an open-source NVIDIA CUDA run-time, is still being worked on at the University of California Santa Cruz in conjunction with PathScale.
After being in development for many years, the xf86-video-nouveau X.Org DDX driver finally saw its first release and it is version 1.0.
Supreet Pal Singh has provided an in-depth overview of his X.Org EVoC project for providing a Fermi scripting engine for the Nouveau driver that will allow for safe and dynamic GPU core / video memory re-clocking on modern NVIDIA GPUs.
With X.Org / Mesa / Wayland not being part of this year's GSoC, the X.Org Foundation is independently paying for some projects to motivate students over to summer to make some open-source driver improvements.
While still not available by default, the Nouveau NV10/NV20 Mesa DRI driver can now handle S3TC texture compression support when available.
An RFC patch-set was published this weekend for providing GPU lock-up recovery support within the Nouveau driver.
One week ago following the committing of the major libdrm re-write for the Nouveau project, the "NVFX" Gallium3D driver was dropped and succeeded by a new "NV30" driver for the GeForce FX/6/7 series GPUs. Unfortunately, for at least some hardware, this Nouveau support is still a busted mess.
The Nouveau Kepler Gallium3D code that was published yesterday does indeed work for allowing OpenGL acceleration on the GeForce 600 series using this reverse-engineered open-source code. In an odd story to end out the weekend, the Nouveau Kepler graphics driver consumed nearly 120GB of hard drive space while running this open-source driver on the NVIDIA GeForce GTX 680.
Over three months passed between the time the Radeon HD 7970 launched and the time that initial Gallium3D support landed (yesterday). So how long is it going to take for a Gallium3D driver for NVIDIA's GeForce GTX 680 "Kepler" that launched just last month and has to be reverse-engineered by the community Nouveau members? Well, as of this afternoon, the Kepler Gallium3D driver is already available.
A massive Nouveau code push went through today affecting libdrm, the Mesa Gallium3D drivers, and the xf86-video-nouveau driver. The whole shebang should offer some performance improvements across the board while one driver has been completely rewritten and affects three generations of hardware.
