[Qemu-devel] Re: Can anybody simply explains how the device model gets run?

[刘鹏程]

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

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
