Writing an operating system kernel from scratch
Follow @popovicu94 I recently implemented a minimal proof of concept time-sharing operating system kernel on RISC-V. In this post, I’ll share the details of how this prototype works. The target audience is anyone looking to understand low-level system software, drivers, system calls, etc., and I hope this will be especially useful to students of system software and computer architecture. This is a redo of an exercise I did for my undergraduate course in operating systems, and functionally it should resemble a typical operating systems project. However, this experiment focuses on modern tooling, as well as the modern architecture of RISC-V. RISC-V is an amazing technology that is easy to understand more quickly than other CPU architectures, while remaining a popular choice for many new…
