Wrong IRQ return by the pci utility or the pci_read_config8 function.
Hello,
I write and interrupt handler for a PCI acquisition board. To obtain the interrupt number of the PCI card i use the
pci_read_config8 and validate the result with the pci utility.
When i use the InterruptAttach function to associate the IRQ to my ISR, nothing append. After many test, i discover
that i must use another interrupt number. In my test, the IRQ obtain by the pci_read_config8 is 0x03 and the IRQ i must
used with the InterruptAttach is 0x17.
Any idea of what append?
Thank you, Sylvain
