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.
Strategic Objectives
- Type-1 Hypervisor: Safety-critical embedded systems foundation
- AUTOSAR C++ Compliance: MISRA C++, MISRA C, DAL-B, DAL-A (avionics), ISO26262
- Aurelio Integration: PikeOS codegen workflow → Aurelio implementation patterns
- IP-XACT Architecture: Agent components as IP Cores with standard interfaces
- Airship Control Foundation: Type-1 hypervisor for cyber-physical simulation control

Project Status
Current Phase: Repository Creation and Environment Setup (Day 1-2)
This repository is being populated with the complete PikeOS ecosystem from the Nextcloud source at cloud.portugalfuturista.org/s/devmm-arch.
Development Environment Setup
See 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
Documentation
- BUILD_ENVIRONMENT.md - Development environment setup and build process
- XSD_WORKFLOW_ANALYSIS.md - XSD → C code generation workflow (planned)
- AUTOSAR_CPP.md - Safety-critical compliance documentation (planned)
- COMPONENTS.md - Component categorization and architecture (planned)
- HYPERVISOR.md - Type-1 hypervisor design documentation (planned)
- AURELIO_INTEGRATION.md - PikeOS → Aurelio integration plan (planned)
