For AAA and ARO based14 configurations, only SCSI functionality is provided.15 16 To compile this driver as a module, choose M here: the17 module will be called aic7xxx.18 19config AIC7XXX_CMDS_PER_DEVICE20 int "Maximum number of TCQ commands per device"21 depends on SCSI_AIC7XXX22 default "32"23 help24 Specify the number of commands you would like to allocate per SCSI25 device when Tagged Command Queueing (TCQ) is enabled on that device.26 27 This is an upper bound value for the number of tagged transactions28 to be used for any device. The aic7xxx driver will automatically29 vary this number based on device behavior. For devices with a30 fixed maximum, the driver will eventually lock to this maximum31 and display a console message indicating this value.32 33 Due to resource allocation issues in the Linux SCSI mid-layer, using34 a high number of commands per device may result in memory allocation35 failures when many devices are attached to the system. For this36 reason, the default is set to 32. Higher values may result in higher37 performance on some devices. The upper bound is 253. 0 disables tagged38 queueing.39 40 Per device tag depth can be controlled via the kernel command line41 "tag_info" option. See Documentation/scsi/aic7xxx.rst for details.42 43config AIC7XXX_RESET_DELAY_MS44 int "Initial bus reset delay in milli-seconds"45 depends on SCSI_AIC7XXX46 default "5000"47 help48 The number of milliseconds to delay after an initial bus reset.49 The bus settle delay following all error recovery actions is50 dictated by the SCSI layer and is not affected by this value.51 52 Default: 5000 (5 seconds)53 54config AIC7XXX_BUILD_FIRMWARE55 bool "Build Adapter Firmware with Kernel Build"56 depends on SCSI_AIC7XXX && !PREVENT_FIRMWARE_BUILD57 help58 This option should only be enabled if you are modifying the firmware59 source to the aic7xxx driver and wish to have the generated firmware60 include files updated during a normal kernel build. The assembler61 for the firmware requires lex and yacc or their equivalents, as well62 as the db v1 library. You may have to install additional packages63 or modify the assembler Makefile or the files it includes if your64 build environment is different than that of the author.65 66config AIC7XXX_DEBUG_ENABLE67 bool "Compile in Debugging Code"68 depends on SCSI_AIC7XXX69 default y70 help71 Compile in aic7xxx debugging code that can be useful in diagnosing72 driver errors.73 74config AIC7XXX_DEBUG_MASK75 int "Debug code enable mask (2047 for all debugging)"76 depends on SCSI_AIC7XXX77 default "0"78 help79 Bit mask of debug options that is only valid if the80 CONFIG_AIC7XXX_DEBUG_ENABLE option is enabled. The bits in this mask81 are defined in the drivers/scsi/aic7xxx/aic7xxx.h - search for the82 variable ahc_debug in that file to find them.83 84config AIC7XXX_REG_PRETTY_PRINT85 bool "Decode registers during diagnostics"86 depends on SCSI_AIC7XXX87 default y88 help89 Compile in register value tables for the output of expanded register90 contents in diagnostics. This make it much easier to understand debug91 output without having to refer to a data book and/or the aic7xxx.reg92 file.93
