Abstract
Dedicated access is provided to a physical input/output (I/O) device which is non-configurable by an initiating logical partition. Access is established by: initiating, by the logical partition, creation of a partition adjunct; invoking a hypervisor of the data processing system to instantiate the partition adjunct with resources donated from the initiating logical partition, the donated resources including a donated virtual address space of the logical partition and the physical I/O device; creating, by the hypervisor, the partition adjunct and assigning the donated virtual address space and donated physical I/O device to the created partition adjunct; and interfacing, by the hypervisor, the logical partition and the created partition adjunct, the interfacing including providing the logical partition with a virtual I/O device which replaces the donated physical I/O device, and which is configurable by the logical partition.
