rust_os

This repository maintains a rust project that tries to create a simple kernel using rust. The kernel as of now can only print on screen using vga buffer and is not interactive.

Dependencies

• bootimage
• bootloader
• x86_64
• spin
• uart_16650
• volatile

Run kernel on QEMU

Build bootable image

• First, install rust's nightly version for your operating system.
• Then install rust-src, by running rustup component add rust-src.
• Install llvm preview tools for rust, rustup component add llvm-tools-preview.
• Now install bootimage to build image, run cargo install bootimage.
• To build it, go to root directory and run cargo build && cargo bootimage.
• This will create a .bin bootable image in target/x86_64/debug/.

Install QEMU

• First, install QEMU/Virt-Manager on your machine, and then install sdl display for QEMU.
• Then reboot your machine to load all dependencies.
• Run qemu-system-x86_64 -drive format=raw,file=<build-bin-location> -display sdl.
