copy-on-write-xv6

✔️ 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.

🔨 Build / Run

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.

📝 Testing copy on write

After opening the emulator you can run:
usertests
cowtest
which include various tests regarding the copy on write problem.
