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.
Mar, 2016: GM20x acceleration support (with redistributable signed firmware) merged in Linux 4.6 and Mesa 11.2
Nov, 2015: Improved Kepler GDDR5 memory clock calculations and PWM-based voltage control merged into 4.4
Jul, 2015: Fermi and newer expose OpenGL 4.1 in Mesa 11.
Apr, 2015: GM107 acceleration support merged into 4.1
