ARI Alternative Routing-ID Interpretation SUpport in Xilinx Root Port

I would like to know if Xilinx Root Port IP supports ARI. As per the PCI SIG spec Root Ports are not supported with ARI functionality. Then my question is how will the Root Port interact with the End Point which is enabled for ARI. Thanks

Hi @vinit.apte 

For PCIe Gen3 US/US+ IP with Root Port you will not have ARI support for selection. ARI is selectable when in End Point and when SRIOV option is selected. Please find attached some details from PCISIG related to ARI.
