    So you're saying Intel just made the hardware without any idea if it was
    useful or not?

    Somehow that seems rather unlikely. It seems to me they had at least one
    but very likely several strong use-cases before they designed the
    hardware.

    What Ingo is asking is to implement these, so that everybody can enjoy
    them instead of being a conduit for Intel proprietary tools.

    A minimal driver with no users except $$ tools is not acceptable.
