Specifically, I'm tied to intel's ICH9 SATA cont= roller and pegged to implement the features if they aren't planned or avail= able. That last part is up in the air, pending what I find out and how long= it'll take. =20 After poking around the mailing list, I found that Soren had mentioned that= he is working on NCQ and I can really only find references to hot plug in = the context of RAID. Is hot plug generally supported for controllers that s= upport it? From experience in another OS, port multiplier was not even on t= he radar as nobody was asking for it, so I'm guessing that the level of int= erest is just as low here. =20 Anyway, any guidance would be greatly appreciated! =20 Thanks!
