Integrated Scheduling in a Real-Time Embedded Hypervisor

Real-Time hypervisors are useful to support the concurrent execution of a general-purpose operating system (GPOS) and a real-time operating system (RTOS) in isolation. However, the integrated nature of real-time embedded systems requires a global approach to scheduling. This paper presents the design and implementation of an integrated scheduling architecture for a real-time hypervisor. The proposed approach makes it possible to mix the priority of each activity in the system (i.e., RTOS and GPOS tasks and interrupt handlers) from a global point of view. Furthermore, the implementation provides the mechanisms to protect the RTOS activities from any potential misbehavior of the activities in the GPOS.
