Abstract:
A computer implemented method, data processing system, and apparatus for hardware resource arbitration in a data processing environment having a plurality of logical partitions. A hypervisor receives a request for a hardware resource from a first logical partition, wherein the request corresponds to an operation. The hypervisor determines the hardware resource is free from contention by a second logical partition. The hypervisor writes the hardware resource to a hardware resource pool data structure, as associated with the first logical partition, in response to a determination the hardware resource is free. The hypervisor presents the hardware resource to the first logical partition. The hypervisor determines that the operation is complete. The hypervisor release the hardware resource from a hardware resource pool, responsive to the determination that the operation is complete.
