LIBATA SATA DRIVER

Back then, there was a generic pci driver, and a driver each for various ropey chipsets. Linux - Hardware This forum is for Hardware issues. If cycle is faster than the fastest known mode, the fasted mode is returned. Schedule error handling for qc. If you are, set everything back to standard and see if you still have problems. So, this is kind of gray area. See the SATA driver features , software status and hardware status.

Note that sense data may indicate ATA bus error e. This function is an EH helper. Return -1 if no iordy mode is available.

This function encapsulates the policy for speed management in one place.

libata (SATA) driver update

On some controllers, command timeout. This function is the first part of the libata error handler which processes a given list of failed commands. Are all drives properly detected in your bios setup? Lihata sense data is acquired, this type of errors can be handled similarly to other SCSI errors.

Disk controllers are usually part of some major ASIC, and failure often causes localized heat distortions in the IC leading aata further failure of the device.

Things were running well until recently when all of these libATA errors began. Inherited from calling layer may sleep. Only one port hanging off the same host can claim the ownership of EH. Many drivers also free driver-private data from port at this time. Pointer to translation function if possible, NULL if not.

Too weak error recovery. The error messages showed up after upgrading from the previous Debian stable to the current stable with saat. Return 1 if the cable appears to be 40 wire. NULL or unspecified entries are inherited from the closet ancestor which has the method and the entry is populated with it.

SCSI will call into this callback when user tries to set queue depth via sysfs. If so what is it? EH will kick in as soon as all commands are drained. This is not as trivial as it seems if we must consider early devices correctly. If a command was available, fill in the SCSI-specific portions of the structure with information on the current command.

libATA Developer’s Guide — The Linux Kernel documentation

The purpose of this half-completion is to use the qc as place holder to make EH code reach this place. Disk Drivers often motherboard chipset drivers have to be compiled into the kernel, not modules, as modules get caught in a Catch situation: Analyze SError if available and further determine cause of failure.

Format string according to fmt and append it to port description. There is single host link but if a PMP is attached to it, there can be multiple pibata links.

Indicate to the mid and upper layers that an ATA command should be retried.

Detach all ports of host. Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.

This hook may be specified as NULL, in which case satz will assume that atapi dma can be swta. For anything other than physical link handling, the default host link is used for both master and slave.
