mooOS 🐮

A toy Unix-like operating system written in Zig.

🎯 Current goal

mooOS is a learning project aimed at creating a simple operating systems that runs on QEMU, targeting a 32-bit RISC-V architecture.

To keep things simple:

• It is designed for single processor.
• It assumes 128 MB of RAM.

My first milestone is to reach user mode and launch a basic shell.

💪 Features implemented so far

• Boot and switch to Zig
• Write messages to consoles with OpenSBI
• Kernel panic handler
• Kernel trap handler (exception)
• Physical memory allocator
