  • Nvidia contributes Tegra K1 support to Nouveau



    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 channels and run
    simple pushbuffers with libdrm (more testing including rendering is in progress
    as we get more familiar with Nouveau's user-space interface).

    I guess my email address might surprise some of you, so let me anticipate some
    questions you might have. :P Yes, this work is endorsed by NVIDIA. Several other
    NVIDIAns (CC'd), including core GPU experts, have provided significant technical
    guidance and will continue their involvement. Special thanks go to Terje
    Bergstrom and Ken Adams for their invaluable GPU expertise, and Thierry Reding
    (at FOSDEM this weekend) for help with debugging and user-space testing.
