Sorry to intervene but just trying to learn from your comments.

but isn't few of PCIe controller's registers itself are mapped
here(base address). So, how can we use this address for MSI?

Or you said from base address of PCIe controller, find an offset that
can be used as MSI address?

Thanks
Amit.

Sorry for nitpicking but at least can we use elegant version of
#ifdefs .i.e. #if IS_ENABLED() here ?

Thanks,
Amit.
