Hi ,


Im writing a network driver under QNX6.5 which supports MSI,but confued by the interrupt number.


when run "pci" command,the output shows the CPU interrupt 0x102.
but "pci_dev_info* info"  filled by pci_attach_device shows that the "info.Irq"  is 2.



which value should I use  when calling InterruptAttach, 0x102 or 2 ???


Please help. thanks.

Re: network driver

You use whatever is returned in the pci_dev_info.Irq structure element. It
should be x102.
