NAME

       ata_tf_to_fis - Convert ATA taskfile to SATA FIS structure

SYNOPSIS

       void ata_tf_to_fis(const struct ata_taskfile * tf, u8 pmp, int is_cmd, u8 * fis);

ARGUMENTS

       tf
	   Taskfile to convert

       pmp
	   Port multiplier port

       is_cmd
	   This FIS is for command

       fis
	   Buffer into which data will output

DESCRIPTION

       Converts a standard ATA taskfile to a Serial ATA FIS structure (Register - Host to Device).

LOCKING

       Inherited from caller.

NAME

     siis -- SiliconImage Serial ATA Host Controller driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device pci
	   device scbus
	   device siis

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   siis_load="YES"

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

     hint.siis.X.msi
     controls Message Signaled Interrupts (MSI) usage by the specified controller.

     hint.siisch.X.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:
     0		   interface Power Management is disabled (default);
     1		   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.

     hint.siisch.X.sata_rev
     setting to nonzero value limits maximum SATA revision (speed).  Values 1, 2 and 3 are respectively 1.5, 3 and 6Gbps.

DESCRIPTION

     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 sep-
     arate 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.

     Same hardware is also supported by the atasiliconimage driver from 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.

HARDWARE

     The siis driver supports the following controllers:
     o	 SiI3124
     o	 SiI3132
     o	 SiI3531

SEE ALSO

     ada(4), ata(4), cam(4), cd(4), da(4), sa(4)

HISTORY

     The siis driver first appeared in FreeBSD 8.0.
