RISC-V OS using Rust: Filesystems

Re:RISC-V OS using Rust: Filesystems by webgoat on Tuesday May 12, 2020 @06:16PM (#23160705)

I've been following along while building an armv7a kernel and I really like how you go back and refactor old parts to match newer rust features like your change to using cargo instead of a makefile and inlining asm files into the rust binary.

My only criticism is that sometimes there's parts in your tutorial that are missing but present in your os. When going through chapter 3/4 I think you skipped over explaining your kmalloc implementation. It's fine that you do since I feel your tutorial should be more about navigating embedded rust than learning os basics, but a note about this task being implemented at some point would've helped.

Thanks for the feedback. It does get tricky to balance going too far into the weeds and keeping it above board. I think a note would be helpful as you suggested.

I do try to put lots of comments in the Rust code to describe what I didn't in the blog for those more interested in the implementation.
