Nouveau Changes Queued For Linux 3.19, Adds Initial GM204 Support

With David Airlie continuing to close the drm-next merge window early prior to the official N-1 kernel release, the open-source NVIDIA/Nouveau driver changes have now landed in Git.

Intel has massive changes for this next kernel and AMD has a lot of changes too while the Nouveau changes come in quite good considering their limited manpower and support from NVDIA Corp.

The changes for Nouveau in the Linux 3.19 kernel will include:

- Tegra K1 voltage support and coherency improvements. The Tegra K1 support with its Kepler-based "GK20A" GPU continue to be improved upon by NVIDIA as they're more interested in open-source driver support here then on the desktop side.

- Initial GM204 GPU support. The GM204 is the new Maxwell GPU found with the GeForce GTX 970 / GeForce GTX 980. However, this initial GeForce GTX 900 series support is limited to just mode-setting. Nouveau developers are still waiting on NVIDIA to provide the necessary signed firmware images for being able to properly initialize the hardware for GPU acceleration.

- GT21x memory re-clocking work. Work is underway for allowing the GeForce GT 210 and friends to be properly re-clocked with regard to their memory. Re-clocking for other NVIDIA GPUs remains a work-in-progress.

- Prep work for "a couple of bigger projects" but these projects weren't finished in time for the Linux 3.19 kernel.

The list of changes can be found via this Git commit.
