# Universalisos - Type-1 Hypervisor Foundation

Universalisos is our safety-critical type-1 hypervisor foundation for cyber-physical systems, created from zero based on PikeOS architecture. This project imports the complete PikeOS ecosystem to serve as the reference architecture and codebase for Aurelio cyber-physical brain development.

## 🎯 **CURRENT STATUS: Complete PikeOS 5.0 Parity Strategy** ✨

**Strategic Objective**: **100% PikeOS 5.0 Functional Parity** 🎯

Universalisos has completed **Stage 1-5** of the type-1 hypervisor implementation, providing:
- ✅ Exception handling and system calls (Stage 2)
- ✅ Priority-based scheduler framework (Stage 2)
- ✅ Memory management with ARMv7 MMU (Stage 3)
- ✅ VM context switching (Stage 3)
- ✅ Device virtualization framework (Stage 4)
- ✅ ARMv7 GIC interrupt controller (Stage 4)
- ✅ **Guest OS boot framework** (Stage 5)
- ✅ **I/O virtualization** (Stage 5)

**Current Implementation**: **15-20% of PikeOS 5.0** (framework foundations)
**Target**: **100% PikeOS 5.0 functional parity** within **15 months** via **Paths A+B+C parallel execution** 🚀

## Project Status

**Current Phase**: Complete PikeOS 5.0 Parity Strategy — Parallel Paths A+B+C Execution

The PikeOS 5.0 ecosystem import is complete. Universalisos has implemented a comprehensive hypervisor foundation through 5 development stages, establishing framework patterns that follow PikeOS architecture. The project now aims for **complete PikeOS 5.0 functional parity** through an ambitious parallel development strategy.

**Development Strategy**: **Paths A+B+C in Parallel** (15 months)
- **Path A (Complete PikeOS Core)**: 12-15 months, 100% PikeOS core functionality
- **Path B (Advanced Virtualization)**: Integrated into Path A for complete parity
- **Path C (Aurelio Integration)**: 6-9 months, agent acceleration across all components

**Implementation Progress**: See [UNIVERSALISOS_VS_PIKEOS_5.0.md](UNIVERSALISOS_VS_PIKEOS_5.0.md) for detailed comparison analysis and roadmap planning.

## Development Environment Setup

See [BUILD_ENVIRONMENT.md](BUILD_ENVIRONMENT.md) for detailed setup instructions.

**Required Toolchains**:
- GCC cross-compilers (ARM, target architectures)
- CMake and Ninja build systems
- AUTOSAR build tools and code generation utilities
- XSD processing tools and validators
- Eclipse IDE for XSD workflow analysis
