SYNOPSIS
adw* at pci? dev ? function ?

options FAILSAFE
options SCSI_ADW_WDTR_DISABLE=mask
options SCSI_ADW_SDTR_DISABLE=mask
options SCSI_ADW_TAGQ_DISABLE=mask
DESCRIPTION
The
adw
driver provides support for the ADW (AdvanSys) ABP-940UW, ASB-3940UW,
ASB-3940U2W
SCSI
host adapters.
The following kernel configuration options are available:
- options FAILSAFE
-
Disables tagged command queuing, wide data transfers and synchronous
data transfers for all
SCSI
devices controlled by the
adw
driver.
By default, tagged command queuing, wide data transfers and
synchronous data transfers are used if the
SCSI
devices support them.
The following options use a
mask
to specify which SCSI peripherals the option applies to.
The
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.
- options SCSI_ADW_WDTR_DISABLE=mask
-
Disable
WIDE
data transfer for the peripherals specified by the mask value.
- options SCSI_ADW_SDTR_DISABLE=mask
-
Disable
SYNCHRONOUS
data transfer for the peripherals specified by the mask value.
- options SCSI_ADW_TAGQ_DISABLE=mask
-
Disable
TAGGED COMMAND QUEUING
for the peripherals specified by the mask value.
