NOUVEAU --
Roy Spliet has been one of the few open-source developers working to tackle re-clocking support for Nouveau so that this open-source, reverse-engineered NVIDIA Linux graphics driver can better perform. He's already published several sets of patches improving various bits of GPU re-clocking through this work that's being funded by the X.Org Foundation. Today he's published another patch series.

Earlier this month Roy Spliet published some basic NVA3 re-clocking patches. Those patches worked on re-clocking improvements for DDR2/DDR3 hardware, implemented wait-for-vblank to remove flickering during memory re-clocking, improvements for reducing the downtime of PFIFO pauses, and other driver bits.

Roy's NVA3 patch series today is memory re-clocking related and has various fixes over the set of six patches. These newest patches can be found on the Nouveau mailing list and he's looking for the work to be merged assuming there's no objections. The Nouveau NVA3 hardware represents various GeForce GT/GTS 200/300 series GPUs and the Quadro FX1800M mobile workstation GPU.


For NVIDIA NVA3 hardware owners wishing to try more experimental code for memory re-clocking, Roy's work-in-progress Git repository for this project can be found on GitHub.

For those wishing to get involved with X.Org / Linux graphics development, the X.Org GSoC 2014 ended semi-successfully but there's always X.Org's Endless Vacation of Code (such as how Roy is currently being funded for this work) and the new X.Org women outreach program.
