LinuxCon EU: Integrating Linux and the Real-Time ERIKA OS Through the Xen Hypervisor
Modern cars, as well as aircrafts, are equipped not only with more and more complex control systems, but also with increasingly advanced user interfaces and infotainment systems. The growing computational demand of these applications can now be met only with multi-core systems, which are actually supplanting single-core ones. Also, safety-critical and non-safety-critical components must be isolated from each other. In this presentation we show a double-OS system, running on a dual-core ARM platform and using the Xen hypervisor to run, in two isolated domains, (1) the automotive-grade ERIKA Enterprise OS, a small-footprint real-time OS suitable for safety-critical control tasks, and (2) a full-featured Linux OS, which is then able to support any complex user interface or multimedia service. The system also provides a basic, safe communication mechanism between the two operating systems.
