摘要：
A system is enabled for configuring an IOMMU to provide direct access to system memory data by at least one I/O device/peripheral. Further, the IOMMU is configured to pass a pointer to at least one I/O device without having to translate the pointer. Further, commands are sent from a process within a guest operating system (OS) directly to a peripheral without intervention from a hypervisor. Further, the IOMMU is configured to grant peripherals access permissions to memory blocks to maintain isolation among peripherals.
