Interesting. We could still allow that by using -device loader though. If we load something in S mode it really is a kernel and not firmware, so I think the -bios argument is a little misleading. We could make -bios and -enable-kvm a warning instead, to discourage users from providing OpenSBI, but still allow them to pass something. To me not allowing it seems reasonable, and we can always re-allow it in the future if there is a good use case. Alistair > > thanks > -- PMM
