Hi,
Im learning device driver programming in Linux. And I'm wondering where I could the IRQ number in the request_irq function.
int request_irq (unsigned int irq, void (*handler) (int, void *, struct pt_regs *), unsigned long irqflags, const char *devname, void *dev_id);
In the irq parameter, what value or where could I find that value to put in the request_irq function?
Thanks
