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.
Ubuntu 12.04 LTS is shipping with the Nouveau driver by default as the open-source (reverse-engineered) NVIDIA graphics driver support, just as they have done in previous releases, but will this cause your mobile device to go through increased power use?
The reverse-engineered Nouveau driver project has two huge surprises to share with the NVIDIA-using Linux desktop community today. One announcement concerns new hardware enablement (Kepler!) and the other concerns the Nouveau driver's position within the Linux kernel.
While it's not often these days that there's worthwhile changes to talk about in an X.Org DDX driver, happening within the Nouveau driver camp in recent weeks has been some improvements to this open-source NVIDIA driver's buffer swap implementation and time-stamping.
Last week I posted an image quality comparison of the Radeon Gallium3D driver versus AMD's Catalyst Linux driver to highlight some visual differences between the open and closed-source Radeon graphics drivers. Now here's a look between the Nouveau Gallium3D driver and NVIDIA's proprietary Linux graphics driver.
For those wondering what the Nouveau project has been up to with their open-source NVIDIA efforts via reverse-engineering besides the working OpenCL support, they have been setting their eyes on video decoding and other areas.
There's another big accomplishment within the open-source graphics camp: Nouveau developers now having an initial working OpenCL implementation for NVIDIA GeForce graphics hardware on the driver that the Linux community developed themselves via reverse-engineering without NVIDIA's support.
Committed to the kernel repository for the open-source Nouveau driver for providing reverse-engineered NVIDIA hardware is now the initial GPU core/memory re-clocking support.
While Nouveau for open-source NVIDIA support in Mesa 8.0 is mixed, the developers behind this reverse-engineered NVIDIA driver are making some progress and hope to have more positive information to report soon.
David Airlie filed a second DRM pull request over the night for the Linux 3.3 kernel. This second pull has work related to NVIDIA Optimus technology within the Nouveau driver.
Last week there were a number of commits to the Nouveau DRM kernel tree by Red Hat's Ben Skeggs, several of these commits bring interesting new features and support.
After reading yesterday's the state of Radeon power management article, for those wondering about the Nouveau driver power management, here's a brief update.
One year after the Radeon and Intel drivers supported precise vblank timestamps, there's a new patch for enabling this support in the open-source NVIDIA (Nouveau) driver.
Ben Skeggs, the Red Hat employee who has been prolific in contributing towards the Nouveau driver project, is in need of some help from NVIDIA laptop owners. If you have a NVIDIA laptop, even the troublesome Optimus laptops, he has a simple chore for you in order to improve Nouveau's support for MXM.
After presenting this week at XDC2011 Chicago about TimeGraph, an open-source GPU command scheduler, and PathScale's GPGPU run-tiume, Shinpei Kato has now taken to the Nouveau list with his proposal.
Martin Peres provided a status update on the Nouveau driver during XDC2011 Chicago. Ben Skeggs, who's employed by Red Hat Australia to work on this open-source NVIDIA driver, was also in attendance at this development conference. Here's some of the key points in terms of future work.
