I'm developing a driver based on RTDM, and i'm having some problems related to IRQ discovery (related to the fact that the driver is starting to do something). So, there is 2 ways to obtain the IRQ number: pci_device -> irq or pci_read_config_byte( pci_device, PCI_INTERRUPT_LINE, (unsigned char*) &irq ) The difference between these is that the 1st presents the "real" irq number (between 1 and 15) and the other presents the "virtual" irq (between 1 and 255). From your experience, is there any problem using the virtual irq number (the 1st option)? Thanks for your answers!!
