Hello parport
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
address?
Thanks all,
Daniel
