I suppose it could be turned into a compile-time/runtime configurable option when VT-d emulation arrives. Unless you mean having both IOMMUs run at the same time, which is impossible unless some meaningful topology is specified (presumably hardcoded as well). Considering this is only a machine model I'm modifying, it's just like other emulated pieces of PC hardware that are (at the moment) hardcoded. Eduard
