rxinu

Rust implementation of Xinu, based on the excellent blog written by Philipp Oppermann

sudo apt-get install gcc qemu -y
curl https://sh.rustup.rs -sSf | sh -s -- -y
export PATH="${PATH}:$HOME/.cargo/bin"
rustup default nightly
rustup component add rust-src
rustup component add llvm-tools-preview
cargo install bootimage
cargo run # run kernel using qemu

Running

Docker

docker build -t rxinu .
docker run -v ${PWD}:/home/rxinu/rxinu -i -t rxinu

QEMU headless mode

There are multiple methods of running QEMU in headless mode. To use the curses option, use the following:

cargo run -- -curses

Other methods

See here for instructions on running the kernel on VirtualBox or on real hardware.

Debugging

See Phillipp Oppermann's blog post regarding gdb to build a gdb binary that can debug x86_64 kernels.

qemu-system-x86_64 -drive format=raw,file=bootimage.bin -d int -s -S &
rust-gdb target/x86_64-rxinu/debug/rxinu -ex "target remote :1234"
