How about a new config option "vtd=enforce" (if you think of selinux you know where that comes from) for the most secure "panic on deviations" to keep "force" working even with buggy BIOSes (which seem to be the majority right now) and to avoid problems for folks currently using "force" with something else in mind rather than their systems panicing after installing a broken BIOS...

I'd also love to see some initiative from Intel to actually make vendors offer proper BIOSes to support the technology they are advertising (and with advertising I do not mean vt-d specifically but advertising a chipset and at the same time Intel saying vt-d is supported on this chipset).


best regards,
   Christian
