Last week was the main set of Nouveau DRM driver changes for the Linux 3.13, which included new power management and re-clocking code for this open-source NVIDIA driver. Prior to David Airlie sending in the DRM pull request a few hours ago, a few more Nouveau changes were merged.
15 November 2013 - Nouveau Changes
The Linux 3.13 kernel has major power management and re-clocking changes -- including automatic fan management by default and initial support for Fermi/Kepler GPU core re-clocking -- and now separate from that work are some more re-clocking improvements. This time around the re-clocking work is for some older NVIDIA integrated/mobile graphics cores.

If you have checked out drm-next since yesterday when Nouveau received new re-clocking and power management code that's still experimental but brings initial support for Fermi and Kepler GPUs, you may have noticed the disappearance of the performance_level sysfs.

Ben Skeggs of Red Hat published his set of kernel DRM driver changes for Nouveau to enter in the Linux 3.13 kernel... The changes are super exciting as they work on new power management and re-clocking support! From my point of view and that of many Linux enthusiasts, the lack of proper re-clocking support has been the number one limitation of this open-source NVIDIA GPU driver.

It's been a while since the last Nouveau X.Org driver update, but last night was marked by the xf86-video-nouveau 1.0.10 release and with it comes a handful of changes.

Samuel Pitoiset of the Nouveau driver project, and the student who was participating in this year's Google Summer of Code, has made great progress in understanding and documenting NVIDIA's "NV50" GPUs performance counters.

While the Nouveau driver has been developed entirely through reverse-engineering the NVIDIA binary blob and is largely developed by community-based developers (many of whom are students), they have made a lot of progress in recent months in pushing forward with new features and functionality for this open-source NVIDIA Linux graphics driver.

Martin Peres gave a status update this week during the XDC2013 X.Org conference on the status of the project but in more particular its big troublesome spot right now: power-management / re-clocking.

The open-source Nouveau graphics driver has supported fan control management on some NVIDIA GPUs for several kernel releases now, but the support hasn't been enabled by default. Fortunately, that may soon change.

For those that were hoping there would be NVIDIA GeForce 400/500/600/700 Fermi/Kepler GPU improvements or better re-clocking or anything fundamentally advanced in the Linux 3.12 kernel for the Nouveau graphics driver, that is not the case.

The open-source Nouveau graphics driver for reverse-engineered NVIDIA hardware support now has initial support for the ARM architecture and as part of that initial enablement for NVIDIA graphics on Tegra SoCs.

There's been a number of Mesa Git commits this morning concerning video acceleration within the Nouveau Gallium3D driver.

The open-source and reverse-engineered Nouveau driver is now able to tap the more recent "VP3" and "VP4" video encode/decode engines on recent NVIDIA GPUs that make up NVIDIA's PureVideo HD technology. With utilizing these VP3/VP4 engines, there can be MPEG-2 and VC-1 acceleration using this hardware.

Precise vBlank timing support has been patched for the Nouveau DRM driver to support the NV50 through NVC0 NVIDIA GPUs (up to and through Fermi but not yet any NVD0 or Kepler hardware).

A set of patches were published this weekend to improve the Nouveau NVIDIA Gallium3D graphics driver's handling of video playback acceleration for certain scenarios.

We now know that the Linux 3.11 kernel has a heck of a lot of AMD Radeon performance potential through the new dynamic power management (DPM) support in its DRM kernel driver, but how's the Nouveau performance? Here's some new benchmarks.

The patches published one month ago for Nouveau NVIDIA Fermi Compute Support on the open-source driver have now been committed to master for the next Mesa release. More importantly this is the base work for implementing NVIDIA performance counters.

While DRI2 PRIME has led to Optimus-like support for laptops with NVIDIA/Intel GPU combinations, one of the problems making this technology less beneficial is the lack of dynamic power management handling. What's the point of keeping one GPU fed with power when it's being unused and just lowering your battery life? Fortunately, a fix is ahead.

The Nouveau driver project is back to needing reverse-engineering data dumps on select NVIDIA graphics processors, which will help in some new re-clocking work. If you're just a Linux desktop user but wanting to help out this reverse-engineered NVIDIA driver project, providing MMIOtrace dumps is a great way to contribute.
