DMA Transfer from PCI-e board to the host

In my scenario I'm implementing a DMA controller on my PCI-e FE board and using it to transfer data from the FE to the host memory. 

Is there any FE --> host interrupt required in this transfer mode (assuming the host knows when new data is available). 

Thanks, 

MA

Generally, there would be an interrupt to indicate completion of a transfer. For a specific case, it depends. Does the device driver expect an interrupt? If the device driver is not written yet, this is something you should discuss with the person who will be writing it.
