The rxv64 operating system
What, you thought we were done with the operating systems written in Rust? Oh sweet summer child. rxv64 is a pedagogical operating system written in Rust that targets multiprocessor x86_64 machines. It is a reimplementation of the xv6 operating system from MIT. As a pedagogical system, it supports very little hardware other than the text-mode CGA device, serial port, PS/2 keyboard controller, and PCIe AHCI SATA storage devices. xv6, in turn, is a reimplementation of Sixth Edition UNIX in C for x86 and RISC-V, widely used in teaching operating systems courses at various universities.
