IRQ number is actually a word coming from ancient time. When 8259 was
popular at that time, we only have 0 ~ 15 interrupts when two 8259 are
cascaded. The IRQ number mattered in that time, because 8259 put their
vector number in the bus for CPU after the interrupt was delivered. The
number
Can anyone explain their relationship and difference among them? It
is very appreciated if you can make some comments. thanks.
I think IRQ number, interrupt number are quite similar things. You can
check PIC [1] first, especially 8259A [2]. When a device raise an interrupt,
the interrupt is

thanks a lot for your help, they are very in theory.:). actually these
concepts all exist in QEMU. I would like to know how they work
together.
It's a mess. qemu_irq is the most fundamental data type we
use to model a general 'pin' or 'signal' line;

IRQ == interrupt.
GPIO is just another name for an input or output pin on a chip which could be a
