x86 kernel

a simple x86 kernel, extended with Rust

this is my work following along with a @phil-opp's blog post series "A minimal x86 kernel"

prerequisites

virtualization

(if you are on OSX, ChromeOS, Windows, etc)

• Vagrant: development environment manager
• XQuartz: X11 Graphics

linux dependencies

• nasm: assembler (assembly -> binary)
• ld: linker (makes binary out of other files)
• grub: creates the bootable iso
• xorriso: req'd by grub, filesystem manipulator
• QEMU: fake-computer emulator

utilities

you don't need these, but they are nice for viewing generated code.

• hexdump: allows you to view generated binary
• objdump: a nicer viewer for .o files

up and running

1. fork and clone this repository

2. navigate into the repo directory: cd x86-kernel

3. $ vagrant up

4. $ vagrant ssh -- -Y -- -Y forwards graphics

5. $ multirust default nightly-2015-11-19

   Sets your default rust to a stable nightly. The features needed to do OS work in Rust are not yet in a stable release, so you must use a nightly build.

6. $ cd /vagrant

   The /vagrant directory is the virtualized directory that is synced with the / directory on your HD.

7. $ make run
