From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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?

There was "Arch Linux ARM" ("ALARM") for a while but all updates that happen to it currently are automations. Stuff breaks more and more from time to time and the maintainer is unresponsive. I am assuming that's why the Asahi project moved to Fedora. And a new proposition inside of Arch Linux allows a "port" to be made but nobody submitted anything. It needs 2 maintainers minimum.

Anyways, so what I am assuming happened is that they just did their own port and never released the build scripts, because of course they would.

From what I've heard, only a small "base" is actually running natively and FEX has it's root set to a specific variant of the "Steam Linux Runtime" (you know, like when you install something on Steam it installs that?) fit to run Steam itself rather than games, but that's just my hypothesis.
