Hmm, this can't be quite correct: you have all those
'op_size * count' in there, which is broken; a REP OUTSD
might read from a lot of memory addresses (op_size * count),
but it writes everything to the *same* 4 bytes in I/O space.
So it really should be 'op_size' as it used to be ...
And b.t.w. I don't think we need to consider the case that
the 4 I/O bytes accessed by a single OUTSD/INSD instruction
are registered by different drivers; if this really happens,
it must be a bug anyway.
Bye,
Ulrich
