NAME¶

SYNOPSIS¶

Alternatively, to load the driver as set of modules at boot time, place some of the following lines in loader.conf(5):

ata_load="YES"

atacard_load="YES"
ataisa_load="YES"
atapci_load="YES"

ataacard_load="YES"
ataacerlabs_load="YES"
ataamd_load="YES"
ataati_load="YES"
atacenatek_load="YES"
atacypress_load="YES"
atacyrix_load="YES"
atahighpoint_load="YES"
ataintel_load="YES"
ataite_load="YES"
atajmicron_load="YES"
atamarvell_load="YES"
atamicron_load="YES"
atanational_load="YES"
atanetcell_load="YES"
atanvidia_load="YES"
atapromise_load="YES"
ataserverworks_load="YES"
atasiliconimage_load="YES"
atasis_load="YES"
atavia_load="YES"

The first line is for the common hardware independent code, and is a prerequisite for the other modules. The next three lines are generic bus-specific drivers. The rest are vendor-specific PCI drivers.

The following tunables are settable from the loader(8):

hw.ata.ata_dma_check_80pin

set to 0 to disable the 80pin cable check (the default is 1, check the cable).

hint.atapci.X.msi

set to 1 to allow Message Signalled Interrupts (MSI) to be used by the specified PCI ATA controller, if supported.

hint.ata.X.devX.mode

limits the initial ATA mode for the specified device on the specified channel.

hint.ata.X.mode

limits the initial ATA mode for every device on the specified channel.

hint.ata.X.pm_level

controls SATA interface Power Management for the specified channel, allowing some power savings at the cost of additional command latency. Possible values:

0

Interface Power Management is disabled. This is the default value.

1

The device is allowed to initiate a PM state change; the host is passive.

hint.ata.X.devX.sata_rev

limits the initial SATA revision (speed) for the specified device on the specified channel. Values 1, 2 and 3 are respectively 1.5, 3 and 6Gbps.

hint.ata.X.sata_rev

Same, but for every device on the specified channel.

DESCRIPTION¶

This driver supports ATA, and for the most of controllers, ATAPI devices. Command queuing and SATA port multipliers are not supported. Device hot-plug and SATA interface power management is supported only on some controllers.

The ata driver can change the transfer mode when the system is up and running. See the negotiate subcommand of camcontrol(8).

The ata driver sets the maximum transfer mode supported by the hardware as default. However, the ata driver sometimes warns: “DMA limited to UDMA33, non-ATA66 cable or device”. This means that the ata driver has detected that the required 80 conductor cable is not present or could not be detected properly, or that one of the devices on the channel only accepts up to UDMA2/ATA33. The hw.ata.ata_dma_check_80pin tunable can be set to 0 to disable this check.

Some of above chips can be configured for AHCI mode. In such case they are supported by ahci(4) driver instead.

Unknown ATA chipsets are supported in PIO modes, and if the standard busmaster DMA registers are present and contain valid setup, DMA is also enabled, although the max mode is limited to UDMA33, as it is not known what the chipset can do and how to program it.
