32 .Nd generic ATA/SATA controller driver
34 To compile this driver into the kernel, place the following lines in your
35 kernel configuration file:
36 .Bd -ragged -offset indent
41 Alternatively, to load the driver as set of modules at boot time,
42 place some of the following lines in
44 .Bd -literal -offset indent
52 ataacerlabs_load="YES"
58 atahighpoint_load="YES"
64 atanational_load="YES"
68 ataserverworks_load="YES"
69 atasiliconimage_load="YES"
74 The first line is for the common hardware independent code, and is a
75 prerequisite for the other modules.
76 The next three lines are generic bus-specific drivers.
77 The rest are vendor-specific PCI drivers.
79 The following tunables are settable from the
82 .It Va hw.ata.ata_dma_check_80pin
83 set to 0 to disable the 80pin cable check (the default is 1, check the cable).
84 .It Va hint.atapci.X.msi
85 set to 1 to allow Message Signalled Interrupts (MSI) to be used by the
86 specified PCI ATA controller, if supported.
87 .It Va hint.ata.X.devX.mode
88 limits the initial ATA mode for the specified device on the specified channel.
89 .It Va hint.ata.X.mode
90 limits the initial ATA mode for every device on the specified channel.
91 .It Va hint.ata.X.pm_level
92 controls SATA interface Power Management for the specified channel,
93 allowing some power savings at the cost of additional command latency.
96 .Bl -tag -width 4n -offset indent -compact
98 Interface Power Management is disabled.
99 This is the default value.
101 The device is allowed to initiate a PM state change; the host is passive.
103 .It Va hint.ata. Ns Ar X Ns Va .dev Ns Ar X Ns Va .sata_rev
104 limits the initial SATA revision (speed) for the specified device
105 on the specified channel.
106 Values 1, 2 and 3 are respectively 1.5, 3 and 6Gbps.
107 .It Va hint.ata. Ns Ar X Ns Va .sata_rev
108 Same, but for every device on the specified channel.
115 subsystem access to the ATA (IDE) and SATA ports
116 of many generic controllers.
117 Depending on the controller, each PATA (IDE)
118 port or each one or two SATA ports are
119 represented to CAM as a separate bus with one or two targets.
120 Most of the bus-management details are handled by the ATA/SATA-specific
122 Connected ATA disks are handled by the ATA protocol disk peripheral driver
124 ATAPI devices are handled by the SCSI protocol peripheral drivers
130 This driver supports ATA, and for the most of controllers, ATAPI devices.
131 Command queuing and SATA port multipliers are not supported.
132 Device hot-plug and SATA interface power management is supported only on
137 driver can change the transfer mode when the system is up and running.
145 driver sets the maximum transfer mode supported by the hardware as default.
148 driver sometimes warns:
149 .Dq Sy "DMA limited to UDMA33, non-ATA66 cable or device".
153 driver has detected that the required 80 conductor cable is not present
154 or could not be detected properly,
155 or that one of the devices on the channel only accepts up
158 .Va hw.ata.ata_dma_check_80pin
159 tunable can be set to 0 to disable this check.

216 Some of above chips can be configured for AHCI mode.
217 In such case they are supported by
221 Unknown ATA chipsets are supported in PIO modes, and if the standard
222 busmaster DMA registers are present and contain valid setup, DMA is
223 also enabled, although the max mode is limited to UDMA33, as it is
224 not known what the chipset can do and how to program it.
226 Please remember that in order to use UDMA4/ATA66 and above modes you
228 use 80 conductor cables.
229 Please assure that ribbon cables are no longer than 45cm.
230 In case of rounded ATA cables, the length depends on the
231 quality of the cables.
232 SATA cables can be up to 1m long according to the specification.
233 External SATA cables can be 2m long and more, but not all controllers
234 work well on long cables, especially at high speeds.
