[Xenomai-help] which way to obtain irq#

[Marcelo Coelho <mjcoelho@domain.hid>]

Hi!


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!!
