Yes, here's the discussion (Feb 2016): https://www.mail-archive.com/qemu-devel@nongnu.org/msg354852.html and it was even part of a pull req (Mar 2016): https://www.mail-archive.com/qemu-devel@nongnu.org/msg359348.html but it wasn't merged, apparently. If QEMU (re)gains this feature, I can try basing the broadcast SMI negotiation on it. Thanks Laszlo
