I am writing a device driver for a custom PMC card, and I'm having trouble with the interrupt service routine.
Although the PCI configuration block says that the board's interrupt is 9, I am receiving interrupt 3. I know that the OpenPIC is supposed to remap the interrupts but I don't quite understand the process. I've looked at the board's users manual and skimmed the Linux kernel but I can't find a good example of what to do. Can anyone provide pointers to documentation, example code, etc. that shows how I can reconcile what the kernel thinks the interrupt is with what in actually being generated? Additional info: I am developing on a Synergy Microsystems VSS4 board. This is a quad-G4 VME board that has the following: IBM MPIC-2 interrupt controller Motorola MPC106 Grackle PCI bridge/memory controller Symbios 53c885 Ethernet/SCSI controller Tundra Universe II PCI-VME64 bridge DEC/Intel 21554 PCI-PCI bridge Thanks for any help.
