The TL;DR is that the organization that controls the HDMI standard won’t allow any open source implementation of HDMI 2.1.
So the hardware is fully capable of it, but they’ll get in trouble if them officially implement it.
Instead it’s officially HDMI 2 (which maxes out at 4k @ 60Hz), but through a technique called chroma sub-sampling they’ve been able to raise that up to 4k @ 120Hz.
However there are some minor reductions in picture quality because of this, and the whole thing would be much easier if the HDMI forum would be more consumer friendly.
In the meantime, the Steam Machine also has display port as a completely issue free display option.



Can’t you just make a DKMS module and create a package for it, and then have it installed as a layer?
I dont know how Arch does atomic, but on Fedora you can (and should) install a couple of akmod packages which get applied as a layer, which is usually nvidia and sometimes wifi drivers.
That being said, I would only expect to see this maybe for the GabeCube since the HDMI hardware will be the same for everyone, so no need to make a hacky module for a wide range of possible cards and setups.
