Hi, I am writing a driver to service an interrupt from our fpga. I am calling request_irq in the open function of my driver. The fpga is connected to external interrupt 1. I am using interrupt number 65 in the request_irq but the function is failing. I traced to a function called setup_irq in file /kernel/irq/manage.c. It fails because at this line: if (desc->chip == &no_irq_chip) . Is 65 the wrong interrupt number? What do I need to do to properly setup for external interrupts?
Thanks for any help, Nick _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
