Nouveau: Accelerated Open Source driver for nVidia cards
The nouveau project aims to build high-quality, free/libre software drivers for nVidia cards. “Nouveau” [nuvo] is the French word for “new”. Nouveau is composed of a Linux kernel KMS driver (nouveau), Gallium3D drivers in Mesa, and the Xorg DDX (xf86-video-nouveau).
2D/3D acceleration supported on all cards; see FeatureMatrix for details.
Experimental support for performance level selection (also known as "reclocking") on Kepler and Tesla G94-GT218 GPUs. Starting Linux 4.5, available in /sys/kernel/debug/dri/0/pstate, previously boot with nouveau.pstate=1 and use /sys/class/drm/card0/device/pstate.
