So it seems that what could be problematic is not getting it to boot but rather how to get proper graphics support. How difficult would it be to reverse engineer the GPU?

And WiFi, audio, ... Basically what's problematic is proper (or any) hardware support.

I'm really not holding out much hope that Linux will natively run on these M1s, even if we get it to boot there's all the driver issues for the integrated GPU, audio, wifi etc.

I'd imagine there is a lot of power management stuff on there too.

One thing I recall is Linus is really big on "absolutely no noise whatsoever". The passively cooled but still reasonably powerful Air seems like ideal hardware for his tastes, at least for a laptop.

How long before the thermal throttling kicks in? I guess if that's the case probably only a performance issue for me when not at home with a laptop cooler underneath.

I believe I saw some estimates that it starts throttling after 8 minutes under load? But I can’t remember the details, unfortunately.

Do we even know how to access the GPU? On x86-based systems there would be a standard bus (PCI/AGP/PCIe) to enumerate the the graphics device, but my impression is ARM doesn't have such things.

A lot of the recent improvement in graphics on Linux has come from manufacturers deciding to become cooperative rather than there being more people reverse-engineering graphics drivers. (Broadcom is contributing support for the Pi 4; AMD added its drivers to upstream; nVidia releases binary drivers to support enterprise customers.)

Honestly, I don't think anyone is holding their breath for the day that corporations like Apple and Microsoft give the world the Linux that they deserve.

Imagine if these power brokers didn't exist and a whole generation of children grew up on Linux rather than Mac/PC. Huge opportunity cost for society in my opinion.

Independent tests show 5-8min of full load before it throttles, which really is quite impressive.
