  • TPH capability is not supported.
  • CCIX is not supported in Versal PL PCIE4. CCIX is only supported in Versal CPM4.
  • Fast PCI Express Endpoint Enumeration using Tandem Configuration is not supported. This use case addresses the ability to initially load a fully configurable PCI Express protocol solution from a small external ROM, so as to meet the 100 ms enumeration requirement. Support for Tandem Configuration for the PL PCIe block in Versal devices is not currently planned.
    Note: Any user requiring fast PCIe enumeration or configuration through PCIe should use the PCIe controllers in the CPM, noting that not all Versal devices contain this particular resource. For details, see Versal Adaptive SoC CPM Mode for PCI Express Product Guide (PG346).
  • Completion timeout for B2, C1, and C2 ranges specified in the device control 2 register is not supported.
