[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] when xen will do callback?
I did see that in setup.c, there that hypercall to setup callbacks like hypervisor_callback, but when xen will issue the callback? Everytime a domain issues a hypervisor call, xen will issue the callback function? Also, I noticed that hypervisor_callback() will in turn call evtchn_do_upcall, which seems to convert the pending flags to the correspond virq and does doIRQ() to emulating irq injection. Is that right? Thanks for your help.
