.Dd March 23, 2015 .Dt SIIS 4 .Os .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: d -ragged -offset indent .Cd "device pci" .Cd "device scbus" .Cd "device siis" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent siis_load="YES" .Ed
p The following tunables are settable from the .Xr loader 8 : l -ohang t Va hint.siis. Ns Ar X Ns Va .msi controls Message Signaled Interrupts (MSI) usage by the specified controller. t 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: l -tag -width 2n -offset indent t 0 interface Power Management is disabled (default); t 1 device is allowed to initiate PM state change, host is passive. .El
p Note that interface Power Management is not compatible with device presence detection. A manual bus reset is needed on device hot-plug. t 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. .El .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.
p 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.
p The activity LEDs of the adapters supported by the .Nm driver can be controlled via the .Xr led 4 API for localization or status reporting purposes. .Sh HARDWARE The .Nm driver supports the following controller chips:
