As a learner of qemu, I am a little bit confused about the qemu device
model.
How the device model gets run and when the device interrupt is raised to
CPU?
In the cpu_exec loop or before it?

Thanks

let me be more specific, for pci nic rtl8139, some callback functions are
registered
during initialization, such as rtl8139_receive, rtl8139_can_receive. When
and how
do these functions get called? My qemu vertion is qemu-0.10.6.
Can anyone generally explain the process? It will be very appreciated.

Thanks
