Ben Skeggs at Red Hat has started queuing up the open-source NVIDIA (Nouveau) driver patches that are being aimed for the Linux 4.4 kernel.

Yesterday he re-based his Git tree against 4.3-rc5 and started pushing in the new Nouveau work for Linux 4.4. So far, most of the patches are work that's already been mentioned:

- There's the Martin Peres work of some work on voltage control. There's support for PWM-based voltage management, support for non-VID-based voltage controllers, and supporting both PWM and GPIO volt management for Kepler GPUs.

- Roy Spliet's work on improved re-clocking for select, older GPUs also landed. The work includes initial re-clocking support for GDDR3-based GPUs from the G94 to G200 hardware.

- Alexandre Courbot of NVIDIA has a few minor patches in the latest Git code. Of course, NVIDIA's Nouveau interest mostly is around ensuring good Tegra graphics support.

- Support for up to 16k width/height for Fermi GPUs and newer while previously it was limited to 8K.

You can find all the latest Nouveau work from Ben's Git repository. Sadly there's been nothing new to report on yet about significant re-clocking improvements for Kepler/Maxwell nor anything new with having NVIDIA release the signed firmware images so the GeForce GTX 900 series hardware-accelerated support can move forward.
