Hello everyone,
I'm writing a driver for some pci hardware and seem to have run into a
problem. I'm kinda new at this, so I went to the kernel hacker's guide to
read up on character devices. I got to the point about the outb and
outb_p functions. In there it says that the port has to be a short. This
is my problem. The card I'm writing the driver for puts its real
registers out of the range accessable by a short. Here's relavent part
of the <cat /proc/ioports>:
efbdc000-efbddffe: ihcp
That REALLY is the IO space for the card's registers. Am I missing
something?
TIA
Pat
