Hi everyone, Way overdue v2 of the final patches that enable basic GK20A support. Hopefully all the issues raised with v1 have been addressed. Changes since v1: - Use gk20a clock driver by Ben instead of twiddling nv04's - Name new classes after gk20a instead of nvea - Addressed comments about BAR initialization code factorization - Removed non-essential code which only purpose was to avoid

Hi everyone, Here is the second batch of patches to add GK20A support to Nouveau. This time we are adding the actual chip support, and this series brings the driver to a point where a slightly-tweaked Mesa successfully runs shaders and renders triangles on GBM! Many thanks to Thierry Reding and the people on the #nouveau IRC channel for their help without which we would not have reached this

Hello everyone, GK20A is the Kepler-based GPU used in the upcoming Tegra K1 chips. The following patches perform architectural changes to Nouveau that are necessary to support non-PCI GPUs and add initial support for GK20A. Although the support is still very basic and more user-space changes will be needed to make the full graphics stack run on top of it, we were able to successfully open
