[Xen-devel] Understanding Xen event channel bit operation

["amin.fallahi@xxxxxxxxx" <amin.fallahi@xxxxxxxxx>]

Hi everybody

I need to understand when these pending and mask bits are set and cleared. It seems pending bits are set by evtchn_set_pending method in event_channel.c but I don't understand where pending bit is cleared by the guest and where mask bit is set and reset?

Can anybody help me with understanding this?

Thanks all
