There aren’t any ARM manufacturers that upstream their drivers, and no SystemReady support from any manufacturers

Basically every package works on ARM, but the lack of manufacturer support for hardware means ARM effectively requires a special kernel build for every PC

RaspberryPi has worked on upstreaming their Broadcom SoC, Collabora had worked on upstreaming the RK3588 SoC…

None of Qualcomm’s recent chips are very usable (always missing something like audio, or other basic functionality)

Asahi Linux worked on Apple M1/M2 support

Unless a new ARM manufacturer comes along, general use ARM PCs are a long way away

Just a heads up, if you’re on the 7040 mainboard, I needed to add this to the kernel command line on Debian 13 for reliable suspend/resume. Without it, the screen would just be grey sometimes and not resume
