How true is this in practice? I know it is certainly the recommended configuration, but interrupt remapping can definitely point ExtINT at arbitrary CPUs, and IIRC, the MP spec simply says that "only one CPU should be configured to receive ExtINT". I know we definitely have bugs with ExiINT handling, but I haven't had time to debug further. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel
