A lightweight separation kernel with dynamic routing capabilities
Twan is a Separation Kernel designed specifically for adaptability, real-time computing, and mixed-criticality workloads. It consists of two distinct components:
- Twanvisor: A hypervisor that leverages hardware assisted virtualisation to isolate partitions. Guests are paravirtualised and use API's provided by Twanvisor.
- TwanRTOS: Root partition operating system that initializes Twanvisor, manages resources, and controls partition policies.
Note: Twan is still in early stages of development.
Twan currently has support for Intel processors with:
- VT-x
- EPTs
- Unrestricted guest
Note: Even if your hardware fits these requirements, be aware that it may not work out of the box.
Twan is not currently ARINC 653 or SKPP compliant out of the box. Certification requires formal verification, safety analysis, and extensive validation beyond the current scope.
