Sending PHYSICAL_ADDRESS in interface structure RRS feed

  • Question

  • Hi ,

    we are developing KMDF driver for PCI-e based Controller where 4 ports are populated on that and they are memory mapped through BAR1. we are creating PDO for each port in the bus driver. I have read this post by "Doron"

    So we are following this way and we need to send the Port Base address in each PDO .,so that they can map in FDO of the Port in port driver.
