  • Alternative Routing-ID Interpretation (ARI).
  • Function Level Reset (FLR).
    Note: Only Ports 0 and 1 support FLR.
  • TLP Processing Hint (TPH).
    Note: TPH supports the "No Steering Tag (ST)" mode only.
  • Address Translation Services (ATS).
  • Process Address Space ID (PasID).
    Note: Scalable IO and Shared Virtual Memory (SVM) may be available in a future Intel® Quartus® Prime release.
  • Configuration Intercept Interface (CII).
  • Soft VirtIO support.
    Note: VirtIO support for Ports 2 and 3 is only available in devices with the suffix R2 or R3 in their OPN number. For additional details on OPN decoding, refer to Intel® Agilex™ FPGAs and SoCs Device Overview.
