Hardware, driver status From ata Wiki.
The SX4 hardware is not fully utilized by the Linux kernel driver. Users may wish to use the Promise driver jntel fully utilize the hardware. The precise cause of this is presently not publicly known but seems likely to be a chipset bug.
CONFIG_SATA_VITESSE: VITESSE VSC-7174 / INTEL 31244 SATA support
Navigation Main page Recent changes Random page. NCQ support added in later chipsets nForce4 and later. The hardware can support this feature, but driver code does not yet exist to support it. Has per-device hardware queues, inhel supports legacy TCQ. This is not yet supported in Linux. No, feature is not present. I make an effort to highlight vendors that support their chipsets by posting hardware documentation publicly open hardware. See also the list of hardware features.
There appear to be some error handling issues in the nForce4 SATA controllers, where system lockups or machine check exceptions can occur when the driver attempts to access the controller registers as part of error handling. This support is now enabled by default.
Similar to ServerWorks “frodo”: Not suited to libata architecture, a separate block driver “sx8” has been written for this hardware. It generally works quite well but there are some known bandwidth limitations which show up with the higher bandwidth requirements from PMP.

Retrieved from ” https: Information on the capabilites of the devices themselves is present in the list of hardware features. Usually due to lack of hardware support for features, such as NCQ.
This has also been known to happen in Windows so it does not appear to be a driver issue. Looks like a standard AHCI controller, but with a satz differences requiring a different driver. Feature will never be implemented. These will be supported by the Marvell libata driver in progress, see above. Views Page Discussion View source History.

Intel PCI-X to Serial ATA (PV N) | FreeNAS Community
Hardware does not support hotplug. This is now not enabled by default due to some reported issues, such as with hotplug and with command timeouts on some systems. In an effort to provide positive reinforcement, I also make an effort to give priority to performing engineering tasks on open hardware. Docs are public itnel This SATA software status has been moved to its own page.
Advanced queueing controller, with full SATA phy control. Note intrl 88 SE xxxx series of chips present an ahci interface. Using the on-board DIMM as cache, and issuing each RAID transaction once instead of once for each diskwill result in increased performance, but the driver doesn’t do that yet.
