I have redone the classical exercise of writing a tiny OS kernel with time sharing, which manages a couple of user threads. My goal was to experiment specifically on RISC-V + OpenSBI. Additionally, I wanted to explore Zig a little bit, so that was the language used instead of the traditional C, but it should be straightforward how to do the same experiment in either C or Rust.
It's definitely very rough around the edges, and it's more of an experiment and an intro for people who want to go through step 0 of learning OS kernel development and computer architecture. Nevertheless, I hope it is still a fun experimental thing to play with over the weekend!
The full walkthrough and the GitHub link are available at the link posted!
This one by the original author was submitted earlier but got no engagement, and is now back with falsified timestamps because of the "second chance pool".
