SiliconImage Serial ATA Host Controller driver
To compile this driver into the kernel, place the following lines in your kernel configuration file:
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
The following tunables are settable from the loader(8):
- controls Message Signaled Interrupts (MSI) usage by the specified controller.
- controls SATA interface Power Management for the specified channel,
allowing some power to be saved at the cost of additional command latency.
- interface Power Management is disabled (default);
- device is allowed to initiate PM state change, host is passive.
Note that interface Power Management is not compatible with device presence detection. A manual bus reset is needed on device hot-plug.
- setting to nonzero value limits maximum SATA revision (speed). Values 1, 2 and 3 are respectively 1.5, 3 and 6Gbps.
This driver provides the CAM(4) subsystem with native access to the 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 ada(4). ATAPI devices are handled by the SCSI protocol peripheral drivers cd(4), da(4), sa(4), etc.
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.
The activity LEDs of the adapters supported by the
siis driver can be controlled via the
led(4) API for localization or status reporting
siis driver supports the following
- SiI3124 (PCI-X 133MHz/64bit, 4 ports)
- SiI3131 (PCIe 1.0 x1, 1 port)
- SiI3132 (PCIe 1.0 x1, 2 ports)
- SiI3531 (PCIe 1.0 x1, 1 port)
- identification LED device nodes
siis driver first appeared in
