This is an initial implementation of HDMI 3D mode support for the nouveau kernel driver. It works on all of the hardware that I have available to test at the moment, but I am unsure as to the overall approach taken for setting HDMI InfoFrames, there's no support for g84 or gf119 disps, and the criteria for enabling stereo support for an output seems a bit iffy. The first four patches arrange

This is the beginnings of HDMI 2.0 support. All of the "extra" features are left out, such as 12/16bpc, YUV420, etc. I've verified that with this code, a GP108 (GT1030) can switch between 4k at 60 and 1920x1080 at 60 on a LG 4K TV. Further, I've verified via i2c tools, that the SCDC writes really do happen. I suspect that the patch for keeping track of the high-speed TMDS
