Hello there,

I've done some initial coding with the ibmgpio driver with my PPC405EP
(PPChamelon) board, and inspired by the "gpio_test.c"-application, I've
succeeded in turning on some attached LEDs on some of the ports, and
reading whether some of the others ports are set high or low using the
(manually) attached pushbutton-switches.

However, the way the application is at the moment I need to poll the
input-ports every so often in order to detect a pushbutton-activation.
Hence, I would like to register an interrupt-handler (of some sort) that
informs me when these events occur. Is that somehow possible?

Best regards,
  Martin Egholm
