🛠️ Development Workflow

1. Edit source code in kernel/ or boot/
2. Build with make all
3. Test in QEMU with make run
4. Debug issues with make debug + GDB
5. Clean build with make clean when needed

📚 Key Design Principles

1. Async-First Architecture

Unlike traditional kernels that rely on threads and blocking operations, CLKernel is built around async primitives:

• All I/O operations are non-blocking
• Actor-based message passing for IPC
• Event-driven processing throughout

2. Hot-Swappable Modularity

The kernel is designed for live updates:

• Modules can be replaced without rebooting
• Dependency tracking prevents unsafe swaps
• Version compatibility checking

3. AI-Augmented Intelligence

The kernel includes an AI supervisor that:

• Monitors system health in real-time
• Predicts potential failures
• Suggests and attempts automatic recovery
• Learns from past incidents

4. Multi-Architecture Support

Built for portability:

• x86_64 primary target
• ARM64 support planned
• Architecture-specific code isolated
• Optimized for both bare metal and virtualization

🤝 Contributing

This is an experimental research project. Contributions are welcome!

1. Focus on one subsystem at a time
2. Maintain the async-first design philosophy
3. Document architectural decisions
4. Test thoroughly in QEMU before submitting
5. Follow the existing code style

📖 Learning Resources

• OS Development: OSDev Wiki
• x86 Assembly: Intel Software Developer Manuals
• Async Design: Actor model and message-passing systems
• AI Integration: Kernel-level fault detection and recovery

⚠️ Current Limitations

• Development Stage: This is experimental research code
• x86_64 Only: ARM64 support is planned but not implemented
• Limited Hardware: Currently supports basic VGA and keyboard only
• No Filesystem: VFS is stubbed out
• No Networking: Network stack is planned
• AI Features Stubbed: AI supervisor is not yet functional
