Kernel from scratch (KFS) series of projects at Ecole 42 !

### [documentation](https://jzck.github.io/kernel/bluesnow/index.html)

# building

  - `nasm` compiles the bootcode
  - `ld` links the bootcode and rust binary
  - `grub-mkrescue` builds the iso
  - `xargo` builds rust code

See `.travis.yml` to get an ubuntu environment ready  
on archlinux `pacman -S rustup make grub xorriso mtools binutils gcc qemu`

#### rust setup

```
rustup override add nightly
rustup component add rust-src
cargo install xargo
```

# running

  - `make iso` builds a bootable iso with grub
  - `make qemu` runs the iso, `make qemu-reload` after a re-build

# todo

  - remove assembly for a pure rust entry point
  - replace grub with something lighter
