xv6 is a re-implementation of Dennis Ritchie's and Ken Thompson's Unix
|
|
|
|
|
Version 6 (v6). xv6 loosely follows the structure and style of v6,

but is implemented for a modern RISC-V multiprocessor using ANSI C.

You will need a RISC-V "newlib" tool chain from

|
|

https://github.com/riscv/riscv-gnu-toolchain, and qemu compiled for

riscv64-softmmu. Once they are installed, and in your shell

search path, you can run "make qemu".
