Question on SATA Hotplug, NCQ and Port Multiplier support

[Sean Thomson]

Howdy Folks,
 
I'm trying to find out what the current/future support for SATA hotplug, NCQ, and Port Multiplier is. Specifically, I'm tied to intel's ICH9 SATA controller and pegged to implement the features if they aren't planned or available. That last part is up in the air, pending what I find out and how long it'll take.
 
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 support it? From experience in another OS, port multiplier was not even on the radar as nobody was asking for it, so I'm guessing that the level of interest is just as low here.
 
Anyway, any guidance would be greatly appreciated!
 
Thanks!
Pat Thomson
