New Patch Series Provides Better Re-Clocking For Some NVIDIA GPUs

Roy Spliet has just published his latest work to better handle re-clocking for select NVIDIA GPUs with the open-source Nouveau driver.

Roy published nine patches yesterday as his latest work on the matter of Nouveau re-clocking, likely the hardest area of the driver for these developers outside of NVIDIA. The new patches add support for G94 and G96 re-clocking (GeForce 9400/9500/9600 series), fixing NV50 waiting for a vblank on re-clocking when no monitor is connected, voltage-related improvements for the GT21x GPUs, and slightly improved Kepler handling of graphics cards with DDR3 video memory. Similar Kepler improvements will eventually happen inspired by these DDR3 changes.

The old GeForce 9600GT will hopefully re-clock better now with this new code.

More details via this patch series. Hopefully these patches plus other re-clocking work will be ready by the time the Linux 4.4 merge window opens up.
