RISC-V OS using Rust: Filesystems

I mean, that's what you'd expect from an OS that was originally for teaching, right? A worked example of the fundamental parts common to most other unix filesystems, just as I would naively expect the minix scheduler to just be round-robin or something, etc.

Well, that was especially true for Minix 1 and 2. Minix 3 is purportedly a production operating system, and ships in every Intel CPU for the last decade or so, right? So while admittedly it may not have significant filesystem needs, it is not purely a teaching operating system anymore.

Nowadays I might point at MIT's xv6, which implements a very similar simple unix filesystem: https://github.com/mit-pdos/xv6-public/blob/master/fs.c

xv6 also was switched to RISC-V (not exactly sure when, but sometime in 2019), and it has a nice book for the actual course.

Course: https://pdos.csail.mit.edu/6.828/2019/xv6.html Book: https://pdos.csail.mit.edu/6.828/2019/xv6/book-riscv-rev0.pd...

Take a look at chapter 7 for the xv6 filesystem referenced here.
