Abstract
A high-performance device interface (HPDI) provides flexible and high-performance access by applications residing in a Virtual Machine (VM) to high-performance devices. The technique enables VM applications to use a single interface even when multiple device drivers exist, and can pass data efficiently between a VM application and a front-end device driver (a device driver implemented in a VM, such as may be used in a paravirtualization environment). It improves overall performance of a VM by reducing the copying of data during communications between a VM application and a front-end device driver, which reduces processor and memory usage.
