.Sh NAME
|
|
.Nm siis
|
|
.Nd SiliconImage Serial ATA Host Controller driver
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following lines in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device pci"
|
|
.Cd "device scbus"
|
|
.Cd "device siis"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
siis_load="YES"
|
|
.Ed
|
|
.Pp
|
|
The following tunables are settable from the
|
|
.Xr loader 8 :
|
|
.Bl -ohang
|
|
.It Va hint.siis. Ns Ar X Ns Va .msi
|
|
controls Message Signaled Interrupts (MSI) usage by the specified controller.
|
|
.It Va hint.siisch. Ns Ar X Ns Va .pm_level
|
|
controls SATA interface Power Management for the specified channel,
|
|
allowing some power to be saved at the cost of additional command
|
|
latency.
|
|
Possible values:
|
|
.Bl -tag -compact
|
|
.It 0
|
|
interface Power Management is disabled (default);
|
|
.It 1
|
|
device is allowed to initiate PM state change, host is passive.
|
|
.El
|
|
Note that interface Power Management is not compatible with
|
|
device presence detection.
|
|
A manual bus reset is needed on device hot-plug.
|
|
.It Va hint.siisch. Ns Ar X Ns Va .sata_rev
|
|
setting to nonzero value limits maximum SATA revision (speed).
|
|
Values 1, 2 and 3 are respectively 1.5, 3 and 6Gbps.
|
|

|
|
.Sh DESCRIPTION
|
|
This driver provides the
|
|
.Xr CAM 4
|
|
subsystem with native access to the
|
|
.Tn SATA
|
|
ports of controller.
|
|
Each SATA port is represented to CAM as a separate bus with 16 targets.
|
|
Most of the bus-management details are handled by the 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
|
|
Driver features include support for Serial ATA and ATAPI devices,
|
|
Port Multipliers (including FIS-based switching), hardware command queues
|
|
(31 command per port), Native Command Queuing, SATA interface Power Management,
|
|
device hot-plug and Message Signaled Interrupts.
|
|
.Pp
|
|
Same hardware is also supported by the atasiliconimage driver from
|
|
.Xr ata 4
|
|
subsystem.
|
|
If both drivers are loaded at the same time, this one will be
|
|
given precedence as the more functional of the two.
|
|

|
