We have been building an interface to attach an HP9000/330 to a
bus developed in our department. Our interface is connected to
the 330 using a GPIO interface. For our application the device
driver written by HP is not very efficient. Therefore we would
like to map the GPIO interface in user space and use our own
driver. Does anyone know where we can find information on the
registers of the GPIO interface and how we can map it in user
space ?
Thanks in advance,
