config SCSI_AIC7XXX
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 Documentation/scsi/aic7xxx.txt 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.
config AIC7XXX_DEBUG_ENABLE
bool "Compile in Debugging Code"
depends on SCSI_AIC7XXX
default y
help
Compile in aic7xxx debugging code that can be useful in diagnosing
driver errors.
config AIC7XXX_DEBUG_MASK
int "Debug code enable mask (2047 for all debugging)"
depends on SCSI_AIC7XXX
default "0"
help
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.
config AIC7XXX_REG_PRETTY_PRINT
bool "Decode registers during diagnostics"
depends on SCSI_AIC7XXX
default y
help
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.
