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
51 ataacerlabs_load="YES"
57 atahighpoint_load="YES"
63 atanational_load="YES"
67 ataserverworks_load="YES"
68 atasiliconimage_load="YES"
73 The first line is for the common hardware independent code, and is a
74 prerequisite for the other modules.
75 The next three lines are generic bus-specific drivers.
76 The rest are vendor-specific PCI drivers.
78 The following tunables are settable from the
81 .It Va hw.ata.ata_dma_check_80pin
82 set to 0 to disable the 80pin cable check (the default is 1, check the cable).
83 .It Va hint.atapci.X.msi
84 set to 1 to allow Message Signalled Interrupts (MSI) to be used by the
85 specified PCI ATA controller, if supported.
86 .It Va hint.ata.X.devX.mode
87 limits the initial ATA mode for the specified device on the specified channel.
88 .It Va hint.ata.X.mode
89 limits the initial ATA mode for every device on the specified channel.
90 .It Va hint.ata.X.pm_level
91 controls SATA interface Power Management for the specified channel,
92 allowing some power savings at the cost of additional command latency.
95 .Bl -tag -width 4n -offset indent -compact
97 Interface Power Management is disabled.
98 This is the default value.
100 The device is allowed to initiate a PM state change; the host is passive.
102 .It Va hint.ata. Ns Ar X Ns Va .dev Ns Ar X Ns Va .sata_rev
103 limits the initial SATA revision (speed) for the specified device
104 on the specified channel.
105 Values 1, 2 and 3 are respectively 1.5, 3 and 6Gbps.
106 .It Va hint.ata. Ns Ar X Ns Va .sata_rev
107 Same, but for every device on the specified channel.
114 subsystem access to the ATA (IDE) and SATA ports
115 of many generic controllers.
116 Depending on the controller, each PATA (IDE)
117 port or each one or two SATA ports are
118 represented to CAM as a separate bus with one or two targets.
119 Most of the bus-management details are handled by the ATA/SATA-specific
121 Connected ATA disks are handled by the ATA protocol disk peripheral driver
123 ATAPI devices are handled by the SCSI protocol peripheral drivers
129 This driver supports ATA, and for the most of controllers, ATAPI devices.
130 Command queuing and SATA port multipliers are not supported.
131 Device hot-plug and SATA interface power management is supported only on
136 driver can change the transfer mode when the system is up and running.
144 driver sets the maximum transfer mode supported by the hardware as default.
147 driver sometimes warns:
148 .Dq Sy "DMA limited to UDMA33, non-ATA66 cable or device".
152 driver has detected that the required 80 conductor cable is not present
153 or could not be detected properly,
154 or that one of the devices on the channel only accepts up
157 .Va hw.ata.ata_dma_check_80pin
158 tunable can be set to 0 to disable this check.

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