Making NetBSD Multiboot-Compatible (2007)
MMU is also responsible for translating between physical and virtual memory addresses. Making virtual memory support optional is a non-trivial design goal; you're not only allowing userspace to peek at (or straight up overwrite) kernel memory, you also need every executable to be a PIE, or to swap it out to disk as a part of a context switch.
Check out RetroBSD <https://github.com/RetroBSD/retrobsd> and LiteBSD <https://github.com/sergev/LiteBSD>; there's a PID 0 (or 1? IIRC) that is called the "swapper" process, which is in charge of implementing the context switching. Fascinating stuff!
