It all depends on your platform. It either comes from the firmware/bios
or it is in the device tree information. The kernel itself doesn't know

Hi Guys,
I want to know how the irq number is derived in linux kernel.
In kernel we are using below function for registering ISR.
int *request_threaded_irq*(unsigned int irq, irq_handler_t handler,
irq_handler_t thread_fn, unsigned long irqflags, const char *devname,
void *dev_id)
1st arg is irq
