  • Device, method and computer program product for multi-level address translation
    Patent number: 7600093
    Abstract: A method for retrieving information from a storage unit, the method includes: receiving, by an input output memory management unit second-level translation information representative of a partition of a storage unit address space; receiving, by a input output memory management unit, a direct memory access request that comprises a consumer identifier and a second memory address that was first-level translated by a communication circuit translation entity; performing, by the input output memory management unit, a second-level translation of the second memory address such as to provide a third memory address, in response to the identity of the consumer; and accessing the storage unit using the third memory address.

  • Method and system for debugging Ethernet
    Patent number: 7539932
    Abstract: A system is disclosed and claimed for debugging Ethernet adapters and Ethernet adapter device drivers by automatically monitoring Ethernet adapter functionality and automatically turning on debug traces upon detecting incorrect Ethernet adapter functionality. An embodiment maintains a counter representing the number of incorrect Ethernet adapter functionality events minus the number of correct Ethernet adapter functionality events. If the counter reaches a threshold value, the Ethernet adapter device driver automatically enables debug traces for storing functionality information to a trace table.
