But if we really want to be 100% compliant, we could consider dropping to PIO0 for the command. Not worth it, though, as in practice this is not necessary, and it would mess up libata far more than is worthwhile for this effort.
I think it only requires the *host* to drop to PIO0 timings. In which case it should be achievable w/o libata modification -- if the driver has to "snoop" command and turn off prefetch, why not switch to PIO0 temporarily?
