No, feature is not present. Not suited to libata architecture, a separate block driver “sx8” has been written for this hardware. Docs are public yay! Views Page Discussion View source History. This support is now enabled by default. Information on the capabilites of the devices themselves is present in the list of hardware features.

Linux Kernel Driver DataBase: CONFIG_SATA_VITESSE: VITESSE VSC / INTEL SATA support
These will be supported by the Marvell libata driver in progress, see above. Feature will never be implemented. Sat SX4 hardware intdl not fully utilized by the Linux kernel driver. The following companies have helped sponsor work on libata, either through Jeff Garzik’s work with Red Hat, or through donations of hardware, or through access to hardware documentation, or through access to engineers. Usually due to lack of hardware support for features, such as NCQ.
CONFIG_SATA_VITESSE: VITESSE VSC-7174 / INTEL 31244 SATA support
This is not yet supported in Linux. See also the intek of hardware features. This has also been known to happen in Windows so it does not appear to be a driver issue.
This SATA software status has been moved to its own page. Information on the capabilites of the devices themselves is present in the list of hardware features. Contents 1 Recent updates 2 Hardware support 2. I make an effort to highlight vendors that support their chipsets by posting hardware documentation publicly open hardware. In an effort to provide positive reinforcement, I also make an effort to give priority to performing engineering tasks on open hardware.
Users may wish to use the Promise driver to fully utilize the hardware. This is now not enabled by default due to some reported issues, such as with hotplug and with command timeouts on some systems.
Note that 88 SE xxxx series of chips present an ahci interface. Hardware does not support hotplug. No, feature is not present. Advanced queueing controller, with full SATA phy control. NCQ support added in later chipsets nForce4 and later. There appear to be some error handling issues in the nForce4 SATA controllers, where system lockups or machine safa exceptions can occur when the driver attempts to access jntel controller registers as part of error handling.
Has per-device hardware queues, and supports legacy TCQ. The hardware can support this feature, but driver code does not yet exist to support it. Navigation Main page Recent changes Random page. 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. Docs are public yay! This support is now enabled by default.
Looks like a standard AHCI controller, but with a few differences requiring a different driver. Similar to ServerWorks “frodo”: Not suited to libata architecture, a separate block driver “sx8″ has been written for this hardware. Retrieved from ” https: Hardware, driver status From ata Wiki. Views Page Discussion View source History. It generally works quite well but there are some known bandwidth limitations which show up with the higher bandwidth requirements from PMP.
The precise cause of this is presently not publicly known but seems likely to be a chipset bug.
