Methylenix

An operating system written in Rust

About

Methylenix is an operating system written in Rust. Except for the boot sequence and some special instructions, All processes are written in Rust.

This is my hobby project. I'm not aiming for practical use.

The origin of the name Methylenix comes from the methylene group. I aimed to develop a UNIX-like OS by combining modules like organic compounds.

Therefore, I named this OS Methylene-nix, Methylenix.

The origin (Japanese)

このプログラムの原点は、セキュリティ・キャンプ全国大会2017 集中コース 「X 言語やOSを自作しよう」に受講生として参加した際に開発を行ったことです。 セキュリティ・キャンプについては、セキュリティ・キャンプ：IPA 独立行政法人 情報処理推進機構 をご覧ください。

セキュリティキャンプでは割り込みまでを実装しました。(セキュリティキャンプ2017参加記 | PG_MANAの雑記)

Build

Dependencies

• rustc (nightly)
• cargo
• grub2-mkrescue (x86_64 only)

Steps

x86_64

git clone https://github.com/PG-MANA/Methylenix.git
cd Methylenix
rustup target add x86_64-unknown-none
cargo xtask build x86_64 --release

The kernel will be placed in bin/.

You can download built images from https://repo.taprix.org/pg_mana/methylenix/images/x86_64 .

AArch64

git clone https://github.com/PG-MANA/Methylenix.git
cd Methylenix
rustup target add aarch64-unknown-uefi
rustup target add aarch64-unknown-none-softfloat
cargo xtask build aarch64 --release

The kernel will be placed in bin/.

You can download built images from https://repo.taprix.org/pg_mana/methylenix/images/aarch64 .

Run on the QEMU

x86_64

qemu-system-x86_64 -cpu qemu64,+fsgsbase --cdrom bin/img/boot.iso

# or (OVMF)
qemu-system-x86_64 --cdrom bin/img/boot.iso -cpu qemu64,+fsgsbase -smp 2 -m 512M -bios /usr/bin/OVMF/OVMF.fd

# or (to emulate host cpu)
qemu-system-x86_64 --cdrom bin/img/boot.iso  -cpu host -smp 2 -m 512M -bios /usr/bin/OVMF/OVMF.fd --enable-kvm

# NIC and NVMe Emulation
