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

Hi Ben, still _assuming_ it's an issue of the card I thought about why it works with the NVIDIA binary driver. And I can image they're just trying to do an identity-mapping first and if that doesn't work (e.g. the particular SOR is already in use by another macro link) they just pick the next suitable one. So the case would be that the NVIDIA binary driver always assignes the only

This is a collection of nouveau debug prints, memory leak, a very annoying race condition causing system hangs with prime scenarios, and a fix from Lyude to get the panel on my laptop working. I'd like to get these into 6.7, Dave.
