Nouveau Engine Reclocking Fixes Continue, NVIDIA Maxwell Re-Clocking Achieved

Independent Nouveau developer Karol Herbst continues to be hard at work on improving the re-clocking state of the open-source NVIDIA Linux driver stack.

Herbst today submitted his fifth version of a massive patch set to fix engine re-clocking. These re-clocking fixes should benefit GeForce GTX 400/500 "Fermi" hardware up through the latest Maxwell cards, but don't expect nothing yet for Pascal until NVIDIA releases that signed firmware to provide accelerated hardware support on this open-source driver.

But it is an achievement that Karol appears to have got some GTX 900 "Maxwell (2)" re-clocking going. He commented, "As a bonus point, it indeed enables memory and engine reclocking on maxwell1 GPUs (maxwell2 works, too, but it is currently a bit too messy to actually do it, but it works)." The original Maxwell is the GTX 750 series while "Maxwell 2" is the GTX 900 cards.

Hopefully this code will be ready for merged into Linux 4.9 as am quite excited about any re-clocking improvements (particularly if Maxwell will get into a working state!) for offering better performance out of the open-source NVIDIA driver stack. More details via this mailing list patch series.
