Hello,

I have good news because, I arrived to validated driver with IRQ 
support. I changed position of cifx on my motherboard in my PC and the 
IRQ affected is not shared ;-) !

I have now a question about IRQ. What is the good method to signal to 
user-land that there is an IRQ. Is there an example ?

Thank you for your help,

Jerome
