    摘要: Embodiments of the present invention are directed to methods for virtualizing interrupt modes on behalf of interrupt-generating devices, including I/O-device controllers, so that newer interrupt-generating devices that lack older interrupt modes can be used in systems that continue to rely on older interrupt modes. In one embodiment of the present invention, a PCIe switch or PCIe-based host bridge is modified, or a new component introduced, to provide an interrupt-mode virtualizing function, or virtual interrupt-mode interface, that provides a virtual interrupt mode on behalf of interrupt-generating devices, such as I/O-device controllers, to operating systems, BIOS layers, and other components that communicate with the I/O-device controllers.

    摘要: A middle manager and methods are provided to enable a plurality of host devices to share one or more input/output devices. The middle manager initializes each shared input/output device and binds one or more functions of each input/output device to a specific host node in the system, such that hosts may only access functions to which they are bound. The middle manager may also utilize a configuration register map to translate values from the actual configuration register into a unique modified value for each of the plurality of host devices such that each host device may access and use the shared input/output device regardless of the firmware or operating system operating thereon.

    摘要: In one embodiment, a computer system, comprises at least one host node, at least one input/output node coupled to the host node, at least one multi-function device coupled to the input/output node via a switch, and a middle manager processor comprising logic to block an enumeration process in a host node for the multi-function devices behind the switch hierarchy, initiate an enumeration process for the multi-function devices in a manager processor separate from the host node, store a routing table for the switch hierarchy in a memory module coupled to the manager processor, and allocate, in the manager processor, endpoint device resources to the host node.
