What operating systems run on #riscv besides GNU/Linux right now?

Bonus points if they have graphics/video support.

I was thinking about writing a new one but maybe I don’t have to?

@requiem
Alpine Linux has a RISC-V image and doesn't have GNU if that's what you're after...

@requiem
Also probably some BSD thing.

@Linux_in_a_Bit I’m looking for things other than Linux as well.

Bsd is interesting, but I’m really interested in simpler, non-unixy options.

@requiem Oberon has been ported to RV32:

You can try it out on this emulator:

Not very polished and some bugs but very promising.

@mc oh this, this is very exciting!

@mc oh of course @vertigo is involved 😁😁😁

@requiem @mc I'm actually not. I just answered a single question. The student/author did all the hard work! 😏

@requiem there are several in various stages of maturity, but they're all offering a Unix-y user environment.

If you're explicitly looking for something that isn't a Unix clone, consider looking at the AROS project. This is a very complete AmigaOS 3.1 clone that is divorced entirely from the Amiga hardware, so it'll run everywhere from within a Linux host environment to bare metal. There are even (x86, at least) distributions you can install and play with.

Things is, I don't know what their RISC-V story is, so I cannot vouch for them definitively.

Otherwise, I'm slowly working on a Uxn-inspired environment of my own called VM/OS, which is not yet ready for prime-time (It's not even ready for its audition yet), but I'd absolutely love to open it up to contributions and outside development some day.

@requiem FreeRTOS is used on several RISC-V based Espressif (ESP32) chips.

But that's more of a microcontroller thing. Still, you can hook up an LCD panel if you want.

@vertigo @requiem Rikke Solbjørg spoke about the project at FOSS North 2021 (in English). Some network problems for her video, though, but the voice is clear:

@requiem Haiku OS (status: https://www.haiku-os.org/guides/building/port_status/)

Zephyr (https://en.wikipedia.org/wiki/Zephyr_(operating_system))

xv6 (https://en.wikipedia.org/wiki/Xv6)

And I'm sure there are more such beasts.

@thebluewizard what a coincidence (I’ve been playing with #haikuos again).

I’m very interested in the possibility of Haiku on riscv, I wonder how close to usable the HiFive board is?

@requiem I have no clue...never have dabbled with HaikuOS. But I would like to play with it, especially with a new computer, even hopefully with a RISC-V box (can I dream? 😀 ).

@kazriko @requiem Yes. Wirth's own ISA is called RISC 5. Rikke calls this "Wirth RISC 5" in her talk about the port.

@requiem HaikuOS?

@meatlotion I was very happy to learn that progress has been made on this!
