Abstract
A host data processing system method, apparatus, and architecture are provided for sharing a PCIe EP device with one or more lendee data processing systems in a PCIe cluster by extracting an RID value from a received PCIe transaction message corresponding to a PCIe function at the PCIe endpoint device, and then processing the RID value to identify an interconnect target port value which corresponds to a first lendee data processing system which is sharing the PCIe endpoint device, and then routing the PCIe transaction message through an interconnect on the host data processing system using an interconnect target output port corresponding to the first interconnect target port value to deliver the PCIe transaction message to the first lendee data processing system.
