However, it does not behave quite asI had expected.After having done a sti(), I do a force_evtchn_callback() which I though would cause an event to be sent to hypervisor_callback(), which was registered asthe channel callback with HYPERVISOR_set_callacks(). It'll only force a callback if an event is pending. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
