NCQ support is under development. Search the archives for Jens Axboe's
recent patches to support this. I don't know about TCQ.
It's done for ahci, because we have documentation. I have no intention
on working on NCQ for chipset where full documentation is not available.
But the bulk of the code is the libata core support, adding NCQ support
to a sata_* driver should now be fairly trivial (with docs).
I have docs for the Promise NCQ stuff. Once NCQ is fully fleshed out (I
haven't wrapped my brain around it in a couple weeks), it shouldn't be
difficult to add NCQ support to sata_promise.
