XtratuM: An Open Source Hypervisor for TSP Embedded Systems in Aerospace
Abstract
XtratuM is an hypervisor designed to meet safety critical requirements. XtratuM 2.1.0 is a redesign of the former version XtratuM 2.0 (for x86 architectures) to meet safety critical requirements. It has been ported to SPARC v8 arquitecture and specially to the to the LEON2 processor, which is the reference platform for the spatial sector. Adaptation involves a strong effort in redesign to be closer to the ARINC-653 standards. As far as we know, XtratuM is the first hypervisor for the SPARC v8 arquitecture. In this paper, the main design aspects are discussed and the internal architecture described. An initial evaluation of the most significant metrics is also provided.
