Mitrix - My own little OS :)

⚠️ This OS is not meant to be used and it's only purpose is to be a fun project for me to work on and learn from. ⚠️

Mitrix is a x86 Operating System with a monolithic kernel. It supports:

• A very basic filesystem called MIFS
• Mouse
• Keyboard
• Timer (PIT)
• Paging
• Serial logging
• Shared Memory
• Userspace execution
• Multitasking
• EFL32 executables
• Syscall API for userspace
• Doomgeneric port for Mitrix
• Basic shell (VTTY like)

Building

# Build the toolchain
chmod +x ./toolchain/build_tools.sh
./toolchain/build_tools.sh
# Compile the project
make all

Running

After building you can use this to run the OS in QEMU:

make run

The ISO file will be available at build/mitrix.iso so you could burn it on an USB and try it on real hardware.

Editing Environment

This project supports compile_commands.json for LSP servers:

make gen_cc_json

Todo

• Rework tasking with multiple framebuffers
• Add Window Manager
• Maybe port to x86_64
• Move to musl-libc
• Port binutils + gcc
