Linux has run on ARM procs for some time. Software is a little hit or miss, but most things have a compiled build for it at this point. A lot of the big servers are running ARM processors due to potential power savings.

The popularity of the Raspberry Pi really increased the number of projects with ARM builds as well. It's been possible to run a pretty decent desktop stack for 10 or 15 years. When the Pi2B came out.

If you happen to run across a project that is not available on ARM you might give a go at compiling it yourself. About half of the time it's not too difficult and a good beginner project.

Yeah it does but it really vary from vendor, arm much locked down to what vendor do

Linux runs on ARM, as well as on Alpha, ARC, C-Sky, Hexagon, LoongArch, m68k, Microblaze, MIPS, Nios II, OpenRISC, PA-RISC, PowerPC, Power ISA, RISC-V, ESA/390, z/Architecture, SuperH, SPARC, x86, and Xtensa

Raspberry pis are arm based and run linux

Linux runs on just about anything, including arches you've never heard of. With arm, assuming you can get at the bootloader, your largest problem is likely to be assembling a compatible device tree if the manufacturer doesn't provide one.

only the ARM versions

will linux run on arm?

Millions of Raspberry Pi say "yes, it will".

What PC? Some boards run Armbian:

i mean on pc arm

Yes, that too.

I guess most arm devices have only Linux implemented.

The Asahi Project even has Fedora Linux running on Apple Silicon Macs, which are ARM-based.

It is already reality .... Since quite a few years ...

If your system is ARM SystemReady certified, then yes.

Linux will run on a potato, and it doesn't even have to have hardware memory management.

Just like that https://pine64.org/devices/pinebook_pro/

It's already running on a gazillion devices.

Only if you have a very long arm, like Monkey D Luffy.

please take your meds.

Does it work on arm terminals? I want it on a Pip Boy. Do I need to run the Demon Summoning Program in Wine or is there a native ELF class?

My iomega ARM based NAS from 15 years ago runs Debian
