The first line is for the common hardware independent code, and is a

The following tunables are settable from the

|
.Xr loader 8 :
|
|
.Bl -ohang
|
|
.It Va hw.ahci.force
|
|
set to nonzero value for forcing drivers to attach to some known AHCI-capable
|
|
chips even if they are configured for legacy IDE emulation (the default is 1,
|
|
force the attach).
|
|
.It Va hw.ata.ata_dma_check_80pin
|
|
set to 0 to disable the 80pin cable check (the default is 1, check the cable).
|
|
.It Va hint.atapci.X.msi
|
|
set to 1 to allow Message Signalled Interrupts (MSI) to be used by the
|
|
specified PCI ATA controller, if supported.
|
|
.It Va hint.ata.X.devX.mode
|
|
limits the initial ATA mode for the specified device on the specified channel.
|
|
.It Va hint.ata.X.mode
|
|
limits the initial ATA mode for every device on the specified channel.
|
|
.It Va 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:
|
|
.Pp
|
|
.Bl -tag -width 4n -offset indent -compact
|
|
.It 0
|
|
Interface Power Management is disabled.
|

This is the default value.
|
|
.It 1
|
|
The device is allowed to initiate a PM state change; the host is passive.
|
|
.It 2
|
|
The host initiates a PARTIAL PM state transition every time a port becomes idle.
|

.It 3
|
|
host initiates SLUMBER PM state transition every time port becomes idle.

.Pp
|

Modes 2 and 3 are only supported for AHCI.
|
|
.It Va hint.ata. Ns Ar X Ns Va .dev Ns Ar X Ns Va .sata_rev
|

limits the initial SATA revision (speed) for the specified device

on the specified channel.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver gives the
|
|
.Xr CAM 4
|
|
subsystem access to the ATA (IDE) and SATA ports
|
|
of many generic controllers.
|
|
Depending on the controller, each PATA (IDE)
|
|
port or each one or two SATA ports are
|
|
represented to CAM as a separate bus with one or two targets.
|
|
Most of the bus-management details are handled by the ATA/SATA-specific
|
|
transport of CAM.
|
|
Connected ATA disks are handled by the ATA protocol disk peripheral driver
|
|
.Xr ada 4 .
|
|
ATAPI devices are handled by the SCSI protocol peripheral drivers
|
|
.Xr cd 4 ,
|
|
.Xr da 4 ,
|
|
.Xr sa 4 ,
|
|
etc.
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver can change the transfer mode when the system is up and running.
|
|
See the
|
|
.Cm negotiate
|
|
subcommand of
|
|
.Xr camcontrol 8 .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver sets the maximum transfer mode supported by the hardware as default.
|
|
However, the
|
|
.Nm
|
|
driver sometimes warns:
|
|
.Dq Sy "DMA limited to UDMA33, non-ATA66 cable or device".
|
|
This means that
|
|
the
|
|
.Nm
|
|
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
|
|
.Va hw.ata.ata_dma_check_80pin
|
|
tunable can be set to 0 to disable this check.

|
|
Some of above chips are also supported by the more featured
|
|
.Xr ahci 4 ,
|
|
.Xr mvs 4 ,
|
|
and
|
|
.Xr siis 4
|
|
drivers.
|
|
If both drivers are loaded at the same time, those will have precedence.
|
|
.Pp
|
|
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.
|
|
.Sh NOTES
|
|
Please remember that in order to use UDMA4/ATA66 and above modes you
|
|
.Em must
|
|
use 80 conductor cables.
|
|
Please assure that ribbon cables are no longer than 45cm.
|
|
In case of rounded ATA cables, the length depends on the
|
|
quality of the cables.
|
|
SATA cables can be up to 1m long according to the specification.
|
|
External SATA cables can be 2m long and more, but not all controllers
|
|
work well on long cables, especially at high speeds.
