Yet another implementation of MikanOS for aarch64 CPUs, written in Rust.

MikanOS (uchan-nos/mikanos) was originally created by @uchan-nos, who is author of the book ゼロからの OS 自作入門 by Mynavi Publishing Corporation. I tried to port this OS to aarch64 CPUs, written in Rust, built on macOS. For details of this OS and C++ implementation, please refer the original repository.

Note that this repository aims to implement all features of MikanOS, but their design and implementation is customised and optimised for writing in Rust.

Features

• Supports aarch64 (ARM64) CPUs
• Written in Rust (no_std)
• Built on macOS

Prerequisites

• Rust Toolchain (1.65-nightly+)
• QEMU
• dosfstools (macOS only)

Building

Builds a disk image and boots them on QEMU by calling only one command:

make boot

Licencing

Since the original MikanOS is licenced under the Apache 2.0 Licence (see the repo), this repository is also licenced under the licence. For details of the licence, see LICENCE.md.
