How to use MSI-X with PCIe-DMA IP in Arria 10

Hi @Jevon121,

Thanks for reaching out to the Intel Community Forum.

When implementing MSI-X with PCIe Hard IP in Qsys, check the "Implement MSI-X" option in the PCI Express/PCI Capabilities section under the IP Settings tab. User needs to fill in the parameters such as the Table Size, Table Offset, Table BAR Indicator (Table BIR), Pending bit array (PBA) Offset, and PBA BAR Indicator (PBA BIR).

You may refer to the FPGA Wiki link below on how to implement the PCIe MSI-X interrupt in FPGA:

Thanks.
