Is anyone aware of plans to port Asahi changes to make other linux distros, i.e. Ubuntu, and others, to be able to run without additional setup on M1 Macs?
Asahi changes are being done in such a way as to be upstreamable, at which point any kernel derived off of mainline will pick up their fixes, so eventually detault Ubuntu will run on Apple Silicon. Expect a custom kernel that can be setup with a bit of work before then though.
Are you aware of any easy to install distros with such kernels?
