In Root Port (RP) mode, the PCIe subsystem has an AXI streaming interface (DTI) to connect to the system level SMMU. The Address Translation Messages (ATS) from the End Point is routed to the SMMU over the DTI interface. The translated address and any invalidation requests from the SMMU, sent to the PCIe over the DTI interface, is converted to ATS messages and sent to the End Point.
