Finding Memory Address of a Parallel Port on Linux

Question

I'm trying to find the base (memory) address of a parallel port I have connected to my laptop via a PCI express card. Running lspci -v shows that my computer recognizes the parallel port and gives the I/O ports (1000 and 1008) but not the memory address (other entries have both ports and memory locations…this card is the only entry without a memory address). Also, when I look in /proc/ioports I get the same ports given in lspci. However, when I try to use either of those addresses in the program I'm running (EMC2 to control stepper motors), it does not find a parallel port at that address.

What would be really great is if there were an analogue to the Windows Device Manager -> Ports -> Resources. Is there any way to do this in Ubuntu? Is there a standard memory location for PCIe devices?

Edit: The output from lspci -v

04:00.0 Parallel controller: Oxford Semiconductor Ltd Device c110 (prog-if 02)
Subsystem: Oxford Semiconductor Ltd Device c110
Flags: bus master, fast devsel, latency 0, IRQ 18
I/O ports at 1000 [size=8]
I/O ports at 1008 [size=4]

Kernel driver in use: parport_pc

And for reference, another entry that shows the memory location:

0c:03.0 FireWire (IEEE 1394): Agere Systems FW322/323 (rev 61) (prog-if 10)

Answer 1

Try cat /proc/ioports | grep parport to filter the output of ioports.

Answer 2

Quick answer: there is no memory location for the parallel port. Parallel ports only ever have IO ports allocated to them. This is the way parallel port interfaces have worked for decades, and nobody has felt the need to make an incompatible memory mapped interface that would need special drivers.

Now I must ask, why are you intent on finding the port's memory location? What do you want to do with it?
