Default 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?

Best

Thumbs down Re: NCQ support for Linux on the 570 Chipset.

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.
