I do not really know, I did not dig deep. I just saw "Intel IOMMU (VT-d)" in "qemu-system-ppc64 --help" output and concluded there is no easy way. > > > Alex > >> STEXI >> @item -cpu @var{model} >> @findex -cpu >> Select CPU model (@code{-cpu help} for list and additional feature >> selection) >> +@table @option >> +@item compat=power6|power7|power8 >> +(PPC64 only) >> +Enables architecture compatibility mode.

Since 8dfa3a5e "target-ppc: Add "compat" CPU option" (which was a part of client-architecture-support patchset) there is a "compat" option of "-cpu". However it was not documented at all and this is what this patch is trying to do.
