Abstract

We explore a model for mixed-criticality support in seL4, a high-assurance microkernel designed for real-world use. Specifically we investigate how the seL4 model can be extended without compromising its security properties and its general- purpose nature, including high average-case performance. The proposed model introduces reservations, with admission control performed at user level, similar to how seL4 handles spatial resources.
