Abstract: Multiple logical partitions are provided access to a self-virtualizing input/output device of a data processing system via multiple dedicated partition adjunct instances. Access is established by: interfacing each logical partition to one or more associated partition adjunct instances, each partition adjunct instance coupling its associated logical partition to one of a virtual function or a queue pair of the self-virtualizing input/output device, and each partition adjunct instance being a separate dispatchable state and being created employing virtual address space donated from the respective logical partition or a hypervisor of the data processing system, and each partition adjunct instance including a device driver for the virtual function or queue pair of the self-virtualizing input/output device; and providing each logical partition with at least one virtual input/output which is interfaced through the logical partition's respective partition adjunct instance(s) to a virtual function or queue pair of the self-virtualizing input/output device.
