33 .Nd SiliconImage Serial ATA Host Controller driver
35 To compile this driver into the kernel,
36 place the following lines in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
44 Alternatively, to load the driver as a
45 module at boot time, place the following line in
47 .Bd -literal -offset indent
51 The following tunables are settable from the
54 .It Va hint.siis. Ns Ar X Ns Va .msi
55 controls Message Signaled Interrupts (MSI) usage by the specified controller.
56 .It Va hint.siisch. Ns Ar X Ns Va .pm_level
57 controls SATA interface Power Management for the specified channel,
58 allowing some power to be saved at the cost of additional command
63 interface Power Management is disabled (default);
65 device is allowed to initiate PM state change, host is passive.
67 Note that interface Power Management is not compatible with
68 device presence detection.
69 A manual bus reset is needed on device hot-plug.
70 .It Va hint.siisch. Ns Ar X Ns Va .sata_rev
71 setting to nonzero value limits maximum SATA revision (speed).
72 Values 1, 2 and 3 are respectively 1.5, 3 and 6Gbps.
75 This driver provides the
77 subsystem with native access to the
80 Each SATA port is represented to CAM as a separate bus with 16 targets.
81 Most of the bus-management details are handled by the SATA-specific
83 Connected ATA disks are handled by the ATA protocol disk peripheral driver
85 ATAPI devices are handled by the SCSI protocol peripheral drivers
91 Driver features include support for Serial ATA and ATAPI devices,
92 Port Multipliers (including FIS-based switching), hardware command queues
93 (31 command per port), Native Command Queuing, SATA interface Power Management,
94 device hot-plug and Message Signaled Interrupts.
96 Same hardware is also supported by the atasiliconimage driver from
99 If both drivers are loaded at the same time, this one will be
100 given precedence as the more functional of the two.
104 driver supports the following controllers:
