Felix OS

felix is a simple 64-bit hobby operating system written in Rust, designed as an educational and personal exploration into systems programming. It features a monolithic kernel that supports basic multitasking, memory management, and user programs. Built from the ground up with Rust’s strong safety guarantees, felix aims to strike a balance between low-level hardware access and modern software practices. It runs on x86_64 platforms via QEMU and includes a basic shell and ELF binary loader, making it an excellent resource for learning OS fundamentals.

Features

Rust-based monolithic kernel for x86_64
ELF loader for executing user-space programs
Cooperative multitasking with simple scheduling
Memory paging and virtual memory system
VGA text-mode console output for early UI
Custom shell with basic built-in commands
Interrupt and syscall handling
Bootable using a custom or multiboot-compliant loader
Emphasis on educational clarity and modular design
