[ Please keep me in CC as I'm not subscribed to the list] Hello, We are using the “Virtex-5 FPGA Integrated Endpoint Block for PCI Express” in Linux platform. It supports only a single-function(Header Type, Bit 7 is zero), but actually it is having different functions in different Bar’s. It has UART hardware module implemented in the first Base Address Register and MMC host controller in other Base Address Register. We are planning to develop our own pcie based uart driver for UART hardware and planning to use the MMC kernel stack for MMC host controller. By default MMC kernel stack gets attached to this device. In the pcie based uart driver, tried configuring the uart module after getting the pci_dev structure with pci_get_device(not used the pci_register_driver). After that I could able to communicate with the UART registers even though MMC stack is attached to the device. Now I am puzzled and stuck with how to proceed further on UART Interrupt Service Routine for this kind of device. Can I use request_irq() for uart isr, do you have any suggestion on this? Any hint or help would be greatly appreciated.
