I wonder if these open drivers will be permitted to implement HDMI 2.1 (e.g. 8k resolution)? Apparently the HDMI Forum has told AMD they cannot support HDMI 2.1 in their own open source drivers, which infuriatingly means the only way to get 8k over HDMI on Linux right now is to use Nvidia's closed drivers... Are we about to lose HDMI 2.1 entirely on Linux?

(I know, this is ridiculous and we should use DisplayPort instead. I'm just curious.)

NVIDIA can handle HDMI 2.1 with open-source driver as they punt it off to firmware - https://www.phoronix.com/news/NVIDIA-Firmware-Blobs-HDMI-2.1

Thanks!

Now I wonder why AMD can't do the same.

They could. They probably just didn't because they didn't foresee it being a problem.
