int "Maximum number of TCQ commands per device"

default "32"
|
|
---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 inidicating 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 higer 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 drivers/scsi/aic7xxx/README.aic79xx
|
|
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.

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.

help
|
|
Read Streaming is a U320 protocol option that should enhance
|
|
performance. Early U320 drive firmware actually performs slower
|
|
with read streaming enabled so it is disabled by default. Read
|
|
Streaming can be configured in much the same way as tagged queueing
|
|
using the "rd_strm" command line option. See
|
|
drivers/scsi/aic7xxx/README.aic79xx for details.
