Don't think anything uses it at the moment.  You could, in principle, write an 
application that opens the evtchn device in a domU and handles some kind of 
strange messages sent from dom0 that are not handled by anything in kernel.

I don't suppose it needs to be there but OTOH, it's not very big ;-)

Cheers,
Mark

EVTCHN driver in DomainU

[Nauzad Sadry]

Hello folks

I see the EVTCHN driver being initialized as a part of DomainU. XEND
(or domain controller) uses the EVTCHN driver to receive notifications
for events on the control interface.

However there is no XEND (or domain controller) that runs in DomainU. 

So what is the purpose of initializing EVTCHN driver in DomainU

Thanks in advance

Nauzad
