rustboot

A small kernel written in Rust.

It paints the screen bright red and then displays some information. You can write. That's it:

Setup

You need a few things to run rustboot:

1. rust-core
2. Rust's master branch or 0.9 release
3. qemu
4. On x86

• clang
• nasm

5. On ARM

• binutils for arm-none-eabi
• gcc cross-compiler

6. Optionally for debugging

• gdb
• tmux

Clone this repository and update rust-core.

$ git clone https://github.com/pczarn/rustboot.git
$ cd rustboot
$ git submodule update --init
### you can also pull latest rust-core:
$ git submodule foreach git pull origin master

To get edge Rust going, grab it from git:

$ git clone https://github.com/mozilla/rust
$ cd rust
$ ./configure
$ make && make install

Arch Linux

Simply install all dependencies:

# pacman -S qemu nasm rust clang gdb tmux
# yaourt -S gcc-arm-none-eabi

OSX

To set things up on OSX, do this:

Install nasm and qemu from homebrew:

$ brew install nasm
$ brew install qemu

Install latest binutils from source.

$ wget 'ftp://sourceware.org/pub/binutils/snapshots/binutils.tar.bz2'
$ ./configure --target=i386-elf
$ make && make install

Running it

To compile, simply execute make command.

To run, use:

$ make run # emulate default platform (x86)
$ make arch=arm run   # run on ARM
$ make arch=arm debug # debug on ARM
