It would probably be a > good idea to queue this branch for some testing early. <nods> I did the 'perf' test which does use the IPI in an PV guest and in dom0 and it worked. And naturally bootup on an machine with an unholy amount of CPUs (x2APIC) - and also smaller ones. And then the smoke-test that Boris does as well (on a sister lab setup). But it would be good to make sure this patch does not blow anything up. > > David _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
