NCQ support for Linux on the 570 Chipset.

I am considering buying a Nvidia board with the 570 chipset.

Is there NCQ support for the Sata controller under Linux?

If not, when will it arrive?

Unless someone does it, maybe never

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 (patch) as well. Unfortunately, the patch needs debugging, and no one seems to have the time or motivation.

NOTE: Newer NVIDIA chipsets are AHCI, and use the ahci driver rather than the sata_nv driver.
