fyos

A hobbyist operating system written in Rust.

See Writing an OS in Rust.

I use this tutorial as a guide. Things of interest will be implemented on my own.

Prerequisites

• rust-src is needed to build our kernel for our custom target.
• To create a bootable image, install bootimage binary and its denpendency llvm-tools-preview.

$ rustup component rust-src llvm-tools-preview
$ cargo install bootimage

To run the kernel in QEMU, you need to install it yourself.

For Arch Linux:

$ pacman -S qemu-full

Usage

$ cargo run

This will run the built kernel in QEMU.
