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.

Most modern software (games excluded), is dynamically compiled. This means that it’s not all one “bundle” that runs, but rather a binary that calls reusable pieces of code, “libraries” from the binary itself. Wine is dynamically compiled.
What makes modern x86 to arm translators special, is that the x86 binary, like an x86 version of wine, can call upon the arm versions of the libraries it uses — like graphic drivers. It’s because of this that the people on r/emulationonandroid managed to play GTA 5 with 30 fps via the computer version. There definitely is overhead, but it’s not that much, and a beefy machine like this could absolutely handle it.

The Facebook/Meta table had a booth where they had an ARM macbook that was running steam and they were installing games on it.
"Dynamically compiled" and dynamic linking are very different things, and in turn dynamic linking is completely different from system calls and inter-process communication. I'm no emulation expert but I'm pretty sure you can't just swap out a dynamically linked library for a different architecture's build for it at link time and expect the ABI to somehow work out, unless you only do this with a small few manually vetted libraries where you can clean up the ABI. Calling into drivers or communicating with other processes that run as the native architecture is generally fine, at least.
I don't know how much Asahi makes use of the capability (if at all), but Apple's M series processors add special architecture extensions that makes x86 emulation be able to perform much better than on any other ARM system.
I wouldn't deny that you can get a lot of things playable enough, but this is very much not hardware you get for the purpose of gaming: getting a CPU and motherboard combo that costs $1440 (64-core 2.2GHz) or $2350 (128-core 2.6GHz) that performs substantially worse at most games than a $300 Ryzen CPU+motherboard combo (and has GPU compatibility quirks to boot) will be very disappointing if that's what you want it for. Though the same could to a lesser extent be said even about x86 workstations that prioritize core count like Xeon/Epyc/Threadripper. For compiling code, running automated tests, and other highly threaded workloads, this hardware is quite a treat.
You're right, my bad. Dynamic linking and dynamic compilation are different thinks.
The library inter operation is a part of the translation layers that, like fex-emu which is becoming more and more supported by Fedora.

Yes, but usually games are ran with wine which does have a standard set of libraries it uses.
