    VT-d is chipset functionality. So it depends on the chipset.

    At least initially the non Intel chipsets and lowend chips are unlikely
    to get IOMMUs I guess.

    There might be some exceptions. e.g. the GPU vendors seem
    to want to to their own IOMMUs, so perhaps graphic devices
    might have them anyways.
