[Xen-devel] Possible cases for Hypercall "HYPERVISOR_event_channel_op(EVTCHNOP_send, &op)" failure
What are the possible cases (I hope there are not many:)) that this Hypercall might fail, HYPERVISOR_event_channel_op(EVTCHNOP_send, &op)???,With an error value of "-ENOSYS (-38)" on a "HVM"? Thx, Venkat _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I don¹t think it should ever fail like that. That hypercall is always required for PV drivers to work. -- Keir On 19/12/2008 11:06, "Kumar, Venkat" <Venkat.Kumar@lsi.com> wrote:> What are the possible cases (I hope there are not manyJ) that this Hypercall > might fail, HYPERVISOR_event_channel_op(EVTCHNOP_send, &op)???,With an error > value of ³ENOSYS (-38)² on a ³HVM²? > > > Thx, > Venkat > > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
