Sorry if this question is dumb. I am wrting a splitting driver. But when the backend issues a notify_via_evtchn call, the frontend''s irq handler was triggered twice instead of one! Why? Anyone run into similar issue before? Thanks, -x _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
