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: A hardware device interface supporting transaction authentication is described herein. At least some illustrative embodiments include a device, including an interconnect interface, and processing logic (coupled to the bus interface) that provides access to a plurality of functions of the device through the interconnect interface. A first transaction received by the device, and associated with a function of the plurality of functions, causes a request identifier within the first transaction to be assigned to the function. Access to the function is denied if a request identifier of a second transaction, subsequent to the first transaction, does not match the request identifier assigned to the function.
