You mean write to the address that's mapped to BAR in the EP side? PCI doesn't allow hosts to interrupt the EP (AFAIK), so we have to poll for any writes by the host to EP memory. However recently I found "Mailbox" module in dra7xx can be used in conjunction with PCI for PCI host to interrupt EP. I'm yet to add support for using such SoC specific mechanisms for EP interrupts. Thanks Kishon
