Many newer chipsets support the Advanced Host Controller Interface (AHCI), which allows operating systems to universally control them and enable NCQ. DragonFly BSD has supported AHCI with NCQ since 2.3 in 2009. Newer mainstream Linux kernels support AHCI natively, and FreeBSD fully supports AHCI since version 8.0.

Apr 13, 2006 · Does NCQ is supported in linux? I'd like to bye Promise SATA300 TX2 plus controller and two NCQ-capable hdd's for software RAID0. Card support NCQ. Will it works on linux ? If both hdd and controller support NCq - is it enough for NCQ or there must be support by software drive also?

I would like to reproduce this scenario on my Linux PC, but the Linux AHCI driver has NCQ enabled by default. I need to disable NCQ, so I found this website describing how to disable NCQ, but it doesn't work. The Linux PC still reaches 190 MiB/s write performance.

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.

Apr 14, 2015 · While usually not presenting any major features each release cycle, the libata feature pull request for Linux 4.1 is a bit more interesting this time around. Catching my interest from the libata 4.1-rc1 pull request by Tejun Heo is the addition of NCQ Autosense support.

guarantee NCQ support (the adapter flags it in its host capability flags), so I don't know if the newer VIA will get you NCQ support. People have lived happily without NCQ support in SATA for years, I'm sure you could too :-)-- Jens Axboe-To unsubscribe from this list: send the line "unsubscribe linux-kernel" in

Many newer chipsets support the Advanced Host Controller Interface (AHCI), which should allow a generic driver supplied by the operating system to control them and enable NCQ. In fact, newer mainstream Linux kernels support AHCI natively.

This is not yet supported in Linux, mainly because some BIOS do not fill in the necessary (PCI BAR) resources. Update: ICH5 includes support for MSI at its SATA controller in non combined mode. This is not yet supported in Linux. Acard AHCI. Driver name: acard-ahci. Summary: Full NCQ and full SATA control including hotplug and PM.AMD: SB600/700/800, Hudson
https://wiki.archlinux.org/index.php/AHCI
AHCI has two main benefits: support for hot pluggable SATA drives (mimicking USB drives' behavior) and Native Command Queuing (NCQ). It has been present in the Linux kernel since version 2.6.19 and will be loaded automatically in current Arch kernel.
