based SCSI controllers.

config AIC79XX_CMDS_PER_DEVICE

help
|
|
Specify the number of commands you would like to allocate per SCSI
|
|
device when Tagged Command Queueing (TCQ) is enabled on that device.
|
|
|
|
This is an upper bound value for the number of tagged transactions
|
|
to be used for any device. The aic7xxx driver will automatically
|
|
vary this number based on device behavior. For devices with a
|
|
fixed maximum, the driver will eventually lock to this maximum
|
|
and display a console message indicating this value.
|
|
|
|
Due to resource allocation issues in the Linux SCSI mid-layer, using
|
|
a high number of commands per device may result in memory allocation
|
|
failures when many devices are attached to the system. For this
|
|
reason, the default is set to 32. Higher values may result in higher
|
|
performance on some devices. The upper bound is 253. 0 disables
|
|
tagged queueing.
|
|
|
|
Per device tag depth can be controlled via the kernel command line
|
|
"tag_info" option. See Documentation/scsi/aic79xx.rst for details.

The number of milliseconds to delay after an initial bus reset.
|

The bus settle delay following all error recovery actions is
|
|
dictated by the SCSI layer and is not affected by this value.

Default: 5000 (5 seconds)

help
|

This option should only be enabled if you are modifying the firmware
|
|
source to the aic79xx driver and wish to have the generated firmware
|
|
include files updated during a normal kernel build. The assembler
|
|
for the firmware requires lex and yacc or their equivalents, as well
|
|
as the db v1 library. You may have to install additional packages
|
|
or modify the assembler Makefile or the files it includes if your
|
|
build environment is different than that of the author.
