Hello! I'm trying to understand the event channel handling more in detail, and was playing around a bit with the Mini-OS. However, it does not behave quite as I 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 as the channel callback with HYPERVISOR_set_callacks(). The callback is not called until the domain issues a HYPERVISOR_set_timer_op() and thereafter blocks with HYPERVISOR_sched_op(). Is this the expected behavior, or is there something wrong with the Mini-OS or did I simply miss something? -- // Simon _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
