Zusammenfassung:At least one input/output (I/O) firmware partition is provided in a partitioned environment to facilitate access to I/O resources owned by the at least one I/O firmware partition. The I/O resources of an I/O firmware partition are shared by one or more other partitions of the environment, referred to as consumer partitions. The consumer partitions use the I/O firmware partition to access the I/O resources. Since the I/O firmware partitions are responsible for providing access to the I/O resources owned by those partitions, the consumer partitions are relieved of this task, reducing complexity and costs in the consumer partitions.
