The open-source NVIDIA "Nouveau" driver project providing independent, reverse-engineered 3D graphics driver support for GeForce GPUs made a lot of progress in 2017 although not as great as many would have hoped for. But 2018 will hopefully prove to be more interesting.

Ben Skeggs of Red Hat has been working on a few Nouveau DRM changes for the next kernel cycle.

There's some exciting news for open-source NVIDIA "Nouveau" driver users this holiday season!

NVIDIA has done an open-source code drop to end out 2017. It's not as exciting as many would have hoped for in providing Nouveau GPU re-clocking abilities, any improvements to the signed firmware situation, or an open-source Vulkan driver, but there is now an experimental Nouveau allocator to implement their proposed generic device allocator library.

Longtime Nouveau contributors Martin Peres and Karol Herbst presented at this week's XDC2017 X.Org conference at the Googleplex in Mountain View. It was a quick talk as they didn't have a whole lot to report on due to their open-source NVIDIA "Nouveau" driver efforts largely being restricted by NVIDIA Corp.

Karol Herbst has sent out 29 updated patches on Friday for a major rework to the Nouveau clock related code for re-clocking and related functionality. This includes a "hacky workaround" for getting re-clocking to function on GeForce GTX 900 "Maxwell 2" GPUs.
