Yes, read that blog entry to understand how different that hardware is from any other Linux-supported ARM stuff to see how much deep understanding you need to actually bring that support upstream to Linux or Mesa. Some(most?) stuff requires fundamental changes and no LLM is going to design and write it in an uostreamable way.

Debugging is not an issue, Asahi seems to have it figured out, especially with the virtualization. It's the design that takes time.

Meanwhile Omarchy, for example, just brute-forces everything, with ugly patches that work today but cannot be upstreamed as such, so they'll break tomorrow with new kernel release. I really expect them to start struggling a lot going forward with maintaining the support they claim. Regressions may actually kill their effort.
