Fix indentation of config option's help text by adding leading spaces. Generally help text is indented by two more spaces beyond the leading tab <\t> character. It helps Kconfig parsers to read file without error.

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.

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.
