Anything that's turning complete, has enough ram, and has a c compiler can run Linux. Theoretically, you could program a CPLD to run brainfuck and you could still run Linux.

The mainline part is key.

Yes. Any turing complete processor can perfectly emulate any other turing complete processor, whether it is x86, arm, or riscv. Mainline Linux can then run on this emulated processor without modification.

Damn that's gonna be slow.

But I guess speed was not a criterion.

It's technically correct, the best kind of correct.

[–] Tja@programming.dev 4 points 9 months ago

I guess it's the difference of can today vs could if this emulator existed...

"boot" is the next important part. Have you tried reading it in full?

[–] stingpie@lemmy.world 1 points 9 months ago (1 children)

Emulated processors can do the same things as physical processors, including booting from disk.

Boot = Bootstrap

If you've loaded up a virtual CPU first that's not a boot of mainline Linux on the CPU.

[–] stingpie@lemmy.world 1 points 9 months ago

I respectfully disagree. The turning machine is not doing any set-up before the emulated CPU begins execution, and all of the actual BIOS is done by the emulated CPU.
