Intel: My PCIe (PCI Express) IP (Avalon-ST Interface) asserts "app_msi_req" to generate an MSI interrupt, but "app_msi_ack" is not asserted.
Category: PCI Express
tool:-
device:-
Please check whether the interrupt (MSI) issuance settings are correctly set.
From the HOST side, it is necessary to set the PCIe Configuration Register in advance.
（参考）Why does the PCIe Hard IP endpoint not return MSI interrupt message app_msi_ack back to the rootport after app_msi_req is asserted?
