xv6 already runs on RISC-V.
Wow, I am somewhat ashamed to admin that I had never heard of "xv6" until your comment! I found the MIT homepage here: https://pdos.csail.mit.edu/6.1810/2024/xv6.html
Two things standout to me: (1) It was written in 2006. RISC V was not released until 2010 (so says Google). I guess it was ported from x86? (2) Russ Cox is one of the contacts listed on MIT homepage. That guy's digital footprints are enormous.
