It is common for kernels to ensure memory isolation through a piece of hardware called memory management unit (MMU). However an MMU by itself does not provide memory isolation. It is only a tool the kernel can use to ensure this property. In this paper we show how a proof assistant such as Coq can be used to model a hardware architecture with an MMU, and an abstract model of microkernel supporting preemptive scheduling and memory manager. We proceed by making formally explicit the consistency properties that must be preserved in order for memory isolation to be preserved.Lire moins >
