.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the ADW (AdvanSys) ABP-940UW, ASB-3940UW,
|
|
ASB-3940U2W
|
|
.Tn SCSI
|
|
host adapters.
|
|
.Pp
|
|
The following kernel configuration options are available:
|
|
.Bl -ohang
|
|
.It Cd options FAILSAFE
|
|
Disables tagged command queuing, wide data transfers and synchronous
|
|
data transfers for all
|
|
.Tn SCSI
|
|
devices controlled by the
|
|
.Nm
|
|
driver.
|
|
By default, tagged command queuing, wide data transfers and
|
|
synchronous data transfers are used if the
|
|
.Tn SCSI
|
|
devices support them.
|
|
.Pp
|
|
The following options use a
|
|
.Em mask
|
|
to specify which SCSI peripherals the option applies to.
|
|
The
|
|
.Em mask
|
|
is a 16 bit bitfield value. Each bit corresponds to a peripheral ID.
|
|
The LSB (bit 0) corresponds to the peripheral with ID 0.
|
|
The MSB (bit 15) corresponds to the peripheral with ID 15.
|
|
The following features cannot be disabled for the host adapter, which by
|
|
default has ID 7.
|
|
.It Cd options SCSI_ADW_WDTR_DISABLE=mask
|
|
Disable
|
|
.Tn WIDE
|
|
data transfer for the peripherals specified by the mask value.
|
|
.It Cd options SCSI_ADW_SDTR_DISABLE=mask
|
|
Disable
|
|
.Tn SYNCHRONOUS
|
|
data transfer for the peripherals specified by the mask value.
|
|
.It Cd options SCSI_ADW_TAGQ_DISABLE=mask
|
|
Disable
|
|
.Tn TAGGED COMMAND QUEUING
|
|
for the peripherals specified by the mask value.
