Some (untested) other idea... write some "plugin" loaded last (via -d), that would list all buses, then unregister all of them (or a part of the list, for buses known to be a problem..). IOVA discovery would end up as DC, so probably fine (and we have an option to force it if needed). Then after call to rte_eal_init, the application would get a hold of this list, re-register buses... ? I think it could work, but clearly hacky... -- David Marchand
