I've been planning on doing some testing with PMP's and noticed that
sata_sil does not support PMP. Is that a hardware limitation or just
that nobody has implemented it in the driver yet ?
Well, it doesn't support hardware context switching. It probably
supports PMP "the slow way" (one PMP-attached device at a time)
I doubt 3112 can do pmp even "the slow way". It doesn't expose FIS
interface nor does it have PMP field in its SControl register. It just
can't generate PMP-aware FIS.
That answers the question nicely then. Time to upgrade to some 3124's I guess.
