What's the trick to getting PCI parallel port interrupts working.
I am writing a custom kernel module and have not been successful
at getting interrupts on my Intek21 parallel port card (PCI vendor
id=14db, device id=2120). The AVLAB website says that this card
supports interrupt sharing.
When I look in the PCI configuration space for the card I find that
it uses INTA for interrupts. When I look at pci_dev->irq I find that
it is configured to use IRQ 11. I enable the interrupts in the control
port and do the usual registering of my ISR but I get no interrupts.
Are the PCI parallel port registers laid out like the ISA parallel ports?
Are the ECR registers in the same place relative to the base
