Aurora OS

A Rust-native operating system built from scratch with safety, elegance, and transparency at its core.

🌟 Features

• Memory Safe: Built entirely in Rust for guaranteed memory safety without garbage collection
• Bare Metal: No dependence on existing OS kernels or Unix derivatives
• Advanced Memory Management: Buddy allocator, virtual memory with 4-level paging, SLAB heap allocator
• Hardware Ready: Designed for real hardware deployment (tested on Optiplex 3080 Micro)
• Security Focused: SMEP/SMAP protection, guard pages, memory poisoning detection

🚀 Current Status

Phase 3 Complete: Advanced Memory Management System

The kernel includes:

• Physical memory management with buddy allocator
• Virtual memory system with full x86_64 4-level paging
• Kernel heap allocator with hybrid allocation strategy
• Hardware-assisted memory protection features
• Complete bootable 1.5MB image

🧪 Testing

# Build the complete system
make build

# Test in QEMU
make test

# Or run directly
qemu-system-x86_64 -drive format=raw,file=aurora-phase3.img

📖 Documentation

See docs/ directory for detailed implementation documentation.

🎯 Future Work

Next phase implementation will focus on process management including:

• Process Control Blocks (PCBs)
• Task scheduler
• Context switching
• System calls interface
• Process lifecycle management

🛠️ Requirements

• Rust nightly toolchain
• NASM assembler
• LLVM linker (ld.lld)
• QEMU for testing (optional but recommended)
