  • Dynamic bus-based virtual channel multiplexing device driver architecture
    Patent number: 8284768
    Abstract: Dynamic bus-based virtual channel multiplexing may be accomplished by establishing one or more virtual channels with a multiplexing device function driver and a multifunction device coupled to a bus, determining one or more functions to be activated on the device, and for each activated function, launching a second-tier function driver to handle operation of the activated function. The second-tier function driver has a function driver type. Establishment of the one or more virtual channels is accomplished using a multiplexing protocol and multiplexing device function driver with the multifunction device via a bus driver coupled to the bus.
