Supporting runners on 64bit RISC-V

[advancedwebdeveloper]

Two possible scenarios:

1. Running on a Qemu's guest (Linux)
2. Running on a board
   .

Hello @advancedwebdeveloper, thank you for your interest in the extension of Actions Runner.

We're unlikely to extend support to more architectures at this time.

In order for us to be able to support the runner on a new architecture (assuming a Linux OS), two of our dependencies, node v16 and dotnet core must be also supported there. From a cursory search, running them is not trivial on RISC-V.

Node: nodejs/build#2876
Dotnet: dotnet/runtime#36748

I'm closing the issue with the above points in mind.

If you can find an experimental path that works for you, I'd be happy to review a docs PR detailing the process.

An unofficial self-hosted actions runner powered by golang does target linux/risc-v https://github.com/ChristopherHX/github-act-runner, no idea if it really works on risc-v64.

I guess the node16 problem would also apply, without node you can only use composite actions and run steps. actions/checkout depends on node16, so you might need to run git clone manually.

I'm not shure if that path should be documented here, because doesn't use actions/runner at all. It is the same runner which runs on freebsd.

It looks like node now supports riscv64
as well as dotnet/runtime

Sadly it seems pretty broken right now, gave it a try on my StarFive Vision 2 :/

I'm gonna try to give this a shot.
Gonna build dotnet from source for riscv64 and then try to make the runner work. I already got latest Node on there.
Maybe i can get somewhere.

Hello, is there any progress on running github actions on different platforms? I would like to see it running on RISC-V, loongson and so on.

I tried to workaround some checks on this branch https://github.com/dkurt/runner/tree/dkurt/riscv64_runner and got stuck on missing RISC-V RID of dotnet - they does not ship this with x64 package. Node.js ignored for now as @ChristopherHX suggested in #2157 (comment).

Were able to build .NET SDK but there are some errors while compile runner: dkurt/dotnet_riscv#5

Oh, seems like I were finally lucky to run a simple test on my RISC-V board!!! https://github.com/dkurt/github_actions_riscv/actions/runs/7557778218/job/20606841931

@fhammerl since @dkurt has a working proof of concept of running GitHub Actions on RISC-V, would you consider reopening this issue? Even if it's isn't planned in the near future, it would be useful to be able to discuss developments here.
