  • System and method for passing information from one device driver to another
    Patent number: 7506343
    Abstract: A system and method for passing data between a first device driver and a second device driver. Data to be provided to the second device driver is identified in the first device driver. A data exchange interface within a kernel space is invoked by the first device driver. The data exchange interface initializes a physical to Direct Memory Access (DMA) address translation table for the child device based on an identifier of a direct memory access window. The data is provided to the data exchange interface. The data exchange interface, in the kernel space, writes the data to a data structure maintained and used by the second device driver.

  • High performance communications path
    Patent number: 5832239
    Abstract: A computer system, memory, and computer-implemented method for generating at least one high performance communication path is provided. The communication path has a plurality of linked components, including a negotiator and a controller. The method includes the steps of registering the negotiator with the controller (e.g. stream head), verifying acknowledgement of negotiation from each component linked between the negotiator and the controller, and in response to a valid verification, redirecting I/O between the controller and the negotiator.
