Hi,
it seems your "Libata status" page needs some update.
"
NVIDIA
Driver name: *sata_nv*
Summary: No TCQ/NCQ in early chipsets. NCQ support added in later chipsets. Looks like a PATA controller, but with full SATA control including hotplug and PM.
*Update:* NVIDIA has provided information (under NDA) that permits implementation of NCQ support, and a sample Linux implementation <http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/archive/2.6.17-nv-adma.patch.bz2> (patch) as well. Unfortunately, the patch needs debugging, and no one seems to have the time or motivation.
*NOTE:* Newer NVIDIA chipsets are AHCI <http://linux-ata.org/driver-status.html#ahci>, and use the ahci driver rather than the sata_nv driver. "
There have been changes since you wrote the above. ADMA has been incorporated mainstream for a while now and SWNCQ is now in -mm. AHCI support is obvious.
Best regards, Zoltán Böszörményi
