+ <h2>Abstract:</h2>
+ <blockquote>
+ In this paper, we propose and evaluate a virtual instruction set interface
+ between an operating system (OS) kernel and a general purpose processor
+ architecture.  This interface is a set of operations added to a previously
+ proposed virtual instruction set architecture called LLVA (Low Level Virtual
+ Architecture) and can be implemented on existing processor hardware.  The
+ long-term benefits of such an interface include
+ richer OS-information for hardware,
+ greater flexibility in evolving hardware,
+ and
+ sophisticated analysis and optimization capabilities for kernel code,
+ including
+ across the application-kernel boundary transformations.
+ Our interface design (LLVA-OS) contains
+ several novel features for machine-independence and performance, including
+ efficient saving and restoring of (hidden) native state,
+ mechanisms for error recovery, and several primitive
+ abstractions that expose semantic information to the underlying translator and
+ hardware.  We describe the design, a prototype implementation of LLVA-OS 
+ on x86, and our experience porting the Linux 2.4.22 kernel to LLVA-OS.
+ We perform a performance evaluation of this kernel, identifying and
+ explaining the root causes of key sources of virtualization overhead.
