A lot of this comment I don't understand how it applies to the Apple M1. I'm not saying it doesn't. I'm completely ignorant of these things. Am I just missing it?
Apple's M1 chip has a custom GPU built into it. There is no documentation on how that GPU works and Apple hasn't released any.
Making any modern GPU work is a lot of work because of how complicated they are. That's even with the full documentation.
In the Apple M1 case, the GPU will have to be reverse engineered to understand how it works, then a driver will need to be written for Linux that supports it.
