[Xen-devel] virtual interrupt from one domain to another
Is there a way to send interrupt from one domain to another? I have FE/BE pair in different domains and I want to notify them using interrupt. how can I do that? is there a way which most of the FE/BE pair generally use? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

On Xen PV ''processor'', ''event port'' is the basic async notification mechanism and even ''interrupt'' (in native context) is carried by an event port. On Xen HVM ''processor'', ''interrupt'' is still the basic notification and all the ''event ports'' are aggregated into one interrupt line derived from a dummy PCI device. But when referring to FE/BE context, inter-vm event channel is always the way used by all existing FE/BE drivers.
