In the last article, we covered bare metal programming on RISC-V. Please familiarize yourself with that material before proceeding with the rest of this article, as this article is a direct continuation of the aforementioned one.
This time we are talking about RISC-V SBI (Supervisor Binary Interface), with OpenSBI as the example. We’ll look at how SBI can assist us with implementing operating system kernel primitives and we’ll end the article with a practical example using riscv64 virt machine.
