Thanks deeply for your clear explanation!
Let me try to conclude what I learned from your description.
qemu_set_irq() qemu_set_irq()
[ device ] -> [ GIC ] -> [ CPU ]
Detailed:
[device]
=>qemu_set_irq()
[GIC]

Hi,
I have added a new virtual device under qemu/hw, and a device driver in the
source code of guest OS (I use arm linux).
Since I want to add an interrupt to the virtual device, I am tracing the
flow of interrupt simulation of QEMU.
However, I have some questions about the flow of interrupt, and
