+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.
