MSI Interrupt Message Address

Hi, 

I am working on implementation of PCIe driver for IMX6 platform. The basic functionality of driver is working fine and tested. But in case of MSI, i am a bit confused that what should be the value written to MSI message address register in the MSI capabilities register set of EP? I didn't find anything clearly written in the Technical Reference Manual. All it says is that the address should be common in MSI capabilities as well as MSI controller address register. The screenshot is also added for this. 

 

Can anyone please guide me about this? May be there is something that I am overlooking.

 

Thank you in anticipation.
