I set the MSI to request 4 messages.
I connected several irq on RXmirq pcie-interrupt port,
and I've got only one MSI message in host side
I'm using stratix-V and Quartus 14.0
Have you any success requesting 4 messages via MSI before?
If you had migrated this design, was it working with previous Quartus version? If yes, would it be possible for you test with the latest Quartus version?
Also, to seek clarification.
Correct me if wrong, MSI is a transmitted as MWr. How is it able to request MSI?
Do you mean you actually trigger 4 conditions that should activate the 4 MSI MWr to host, but the host is receiving just 1 MSI?
If yes, what is the trigger condition? PCIe error or application error?
