This driver supports all of Adaptec's PCI based SCSI controllers
(not the hardware RAID controllers though) as well as the aic7770
based EISA and VLB SCSI controllers (the 274x and 284x series).
This is an Adaptec sponsored driver written by Justin Gibbs. It is
intended to replace the previous aic7xxx driver maintained by Doug
Ledford since Doug is no longer maintaining that driver.

default "253"
---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.
Note: Unless you experience some type of device failure, the default
value, no enforced limit, should work for you.
Default: 253

include files updated during a normal kernel build. The assembler

or modify the assembler make file or the files it includes if your
build environment is different than that of the author.

config AIC79XX_CMDS_PER_DEVICE
int "Maximum number of TCQ commands per device"
depends on SCSI_AIC79XX
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.
