The hyplet - Joining a Program and a Nanovisor for real-time and Performance

This paper presents the concept of sharing a hyper-visor address space with a standard Linux program. In this work, we add hypervisor awareness to the Linux kernel and execute code in the HYP exception level through using the hyplet. The hyplet is an innovative way to code interrupt service routines and remote procedure calls under ARM. The hyplet provides high performance and run-time predictability. We demonstrate the hyplet implementation using the C programming language on an ARM8v-a platform and under the Linux kernel. We then provide performance measurements, use cases, and security scenarios.
