[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 3/6] [events] Check if the PCI device is owner by a domain different than DOMID_SELF.
We check if there is a domain owner for the PCI device. In case of failure (meaning no domain has registered for this device) we make DOMID_SELF the owner.
