Building MesaOS: A 64-bit Hybrid Kernel written in Rust from Scratch

Описание и применение

MesaOS – это 64‑битный гибридный ядро, написанный с нуля на Rust, поддерживающий драйверы Linux, собственный стек сетевых протоколов, аудио и интерактивную оболочку, работающий в QEMU и реальном железе.

Задача

Developing a 64‑bit hybrid operating system from scratch to learn low‑level systems programming and driver integration.

Результат

MesaOS demonstrates a complete 64‑bit hybrid kernel written in Rust, capable of running Linux drivers, providing networking, audio, storage, and shell functionality, and operating on both virtual and real hardware.

Рабочий процесс

• Define kernel architecture and feature set
• Implement Rust core and bootloader (Limine)
• Create Linux driver shim with 400+ exported symbols
• Develop custom networking stack (Ethernet, ARP, IPv4, ICMP, DHCP, DNS, UDP/TCP parsing)
• Add audio streaming using WAV files and storage model for initrd
• Build interactive shell with 80+ commands and ELF execution
• Test kernel in QEMU and on HP 15s laptop
• Iterate on driver development and state machine design
• Invite contributors for xHCI/USB and Wi‑Fi driver work

Доказательства

The system implements than 400 exported kernel symbols such as kmalloc, printk, pci_* and dma_* so that Linux drivers can be loaded.

Источник

The project has a custom network stack that supports Ethernet, ARP, IPv4 ICMP and allows header parsing for UDP and TCP. It also includes DHCP and DNS support.
