multiple MSI using PCIe with Avalon-MM

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 thanks, mike

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?
