In one embodiment, the present invention includes a method for receiving a request for a direct memory access (DMA) operation in an input/output (I/O) hub, where the request includes a device virtual address (DVA) associated with the DMA operation, determining in the I/O hub whether to perform an address translation to translate the DVA into a physical address (PA), and sending the request with the DVA from the I/O hub to a processor coupled to the I/O hub if the I/O hub determines not to perform the address translation. Other embodiments are described and claimed. |
