Zusammenfassung:Communicating between an application and a hardware device. A method includes an application writing data to host physical memory using an application view of the memory. The method further includes mapping the data in the physical memory to a hardware driver view, usable by a hardware driver, without needing to copy the data to a different physical storage location. The method further includes mapping the data to a hardware accessible view accessible by a hardware device without needing to copy the data to a different physical storage location.
