The PCIe subsystem supports Address Translation Request (ATS) messages in Root Port mode. All PCIe ATS requests are forwarded to the SMMU. The ATS response sent back by the SMMU is forwarded to the remote PCIe requestor.
In End Point mode, the PCIe subsystem supports SR-IOV with 6 physical functions (PF), and 4 virtual functions (VF) per physical function for PF0-PF3 only (6PF/16VF).
