- config SCSI_AIC79XX
- tristate "Adaptec AIC79xx U320 support"
- depends on PCI && SCSI
- select SCSI_SPI_ATTRS
- help
- This driver supports all of Adaptec's Ultra 320 PCI-X
- based SCSI controllers.
- 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 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.aic79xx
- for details.
- config AIC79XX_RESET_DELAY_MS
- int "Initial bus reset delay in milli-seconds"
- depends on SCSI_AIC79XX
- 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 AIC79XX_BUILD_FIRMWARE
- bool "Build Adapter Firmware with Kernel Build"
- depends on SCSI_AIC79XX && !PREVENT_FIRMWARE_BUILD
- 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.
- config AIC79XX_DEBUG_ENABLE
- bool "Compile in Debugging Code"
- depends on SCSI_AIC79XX
- default y
- help
- Compile in aic79xx debugging code that can be useful in diagnosing
- driver errors.
- config AIC79XX_DEBUG_MASK
- int "Debug code enable mask (16383 for all debugging)"
- depends on SCSI_AIC79XX
- default "0"
- help
- Bit mask of debug options that is only valid if the
- CONFIG_AIC79XX_DEBUG_ENBLE option is enabled. The bits in this mask
- are defined in the drivers/scsi/aic7xxx/aic79xx.h - search for the
- variable ahd_debug in that file to find them.
- config AIC79XX_REG_PRETTY_PRINT
- bool "Decode registers during diagnostics"
- depends on SCSI_AIC79XX
- 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.
