Specifically, SteamOS for the Steam Frame. I have so many questions. The Frame runs “SteamOS”. Only SteamOS is based on Arch/x86, and the Frame runs ARM/Qualcomm, so surely this is a sort of “SteamOS for ARM”? I understand FEX (ish), are they just running the entire OS through FEX? Arch doesn’t seem to have an ARM version I can find so did Valve do the work of porting Arch to ARM? And if so, where is the source code?
iirc the difference is that one is trying to port arch linux to arm and the other is trying to have arch linux run on arm without manual modification
