description

This paper presents the concept of a Multi-Exception level operating system. We add a hypervisor awareness to the Linux kernel and execute code in hyp exception level. We do that through the use of Hyplets. Hyplets are an innovative way to code interrupt service routines under ARM. Hyplets provide high performance, security, running time predictability, an RPC mechanism and a possible solution for the priority inversion problem. Hyplets uses special features of ARM8va hypervisor memory architecture.
