tristate "Adaptec AIC7xxx Fast -> U160 support (New Driver)"
|
|
depends on (PCI || EISA) && SCSI
|
|
select SCSI_SPI_ATTRS
|
|
---help---
|
|
This driver supports all of Adaptec's Fast through Ultra 160 PCI
|
|
based SCSI controllers as well as the aic7770 based EISA and VLB
|
|
SCSI controllers (the 274x and 284x series). For AAA and ARO based
|
|
configurations, only SCSI functionality is provided.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called aic7xxx.
|
|
|
|
config AIC7XXX_CMDS_PER_DEVICE
|
|
int "Maximum number of TCQ commands per device"
|
|
depends on SCSI_AIC7XXX
|
|
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 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 drivers/scsi/aic7xxx/README.aic7xxx
|
|
for details.

|
config AIC7XXX_RESET_DELAY_MS
|
|
int "Initial bus reset delay in milli-seconds"
|
|
depends on SCSI_AIC7XXX
|
|
default "5000"
|
|
---help---
|
|
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)

config AIC7XXX_BUILD_FIRMWARE
|

bool "Build Adapter Firmware with Kernel Build"
|
|
depends on SCSI_AIC7XXX && !PREVENT_FIRMWARE_BUILD
|
|
help
|
|
This option should only be enabled if you are modifying the firmware
|
|
source to the aic7xxx 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.

driver errors.

Bit mask of debug options that is only valid if the

CONFIG_AIC7XXX_DEBUG_ENABLE option is enabled. The bits in this mask
|
|
are defined in the drivers/scsi/aic7xxx/aic7xxx.h - search for the

variable ahc_debug in that file to find them.

Compile in register value tables for the output of expanded register
|

contents in diagnostics. This make it much easier to understand debug
|
|
output without having to refer to a data book and/or the aic7xxx.reg
|
|
file.
