Placing Virtual Machine Monitor (VMM) Code in Guest Context to Speed Memory Mapped Input/Output Virtualization

摘要

In one embodiment, a method comprises: obtaining use of one or more pages in a guest physical address space of a guest; storing handler code to process one or more input/output (I/O) and/or interrupt events in the one or more pages; and redirecting a first event of the one or more I/O events from guest handler code that would process the first event to the handler code in the one or more pages. Also contemplated is a computer accessible medium comprising a plurality of instructions, which, when executed by a computer, implement the method.
