7 tristate "Adaptec AIC7xxx Fast -> U160 support"
8 depends on (PCI || EISA) && SCSI
11 This driver supports all of Adaptec's Fast through Ultra 160 PCI
12 based SCSI controllers as well as the aic7770 based EISA and VLB
13 SCSI controllers (the 274x and 284x series). For AAA and ARO based
14 configurations, only SCSI functionality is provided.
16 To compile this driver as a module, choose M here: the
17 module will be called aic7xxx.
19 config AIC7XXX_CMDS_PER_DEVICE
20 int "Maximum number of TCQ commands per device"
21 depends on SCSI_AIC7XXX
24 Specify the number of commands you would like to allocate per SCSI
25 device when Tagged Command Queueing (TCQ) is enabled on that device.
27 This is an upper bound value for the number of tagged transactions
28 to be used for any device. The aic7xxx driver will automatically
29 vary this number based on device behavior. For devices with a
30 fixed maximum, the driver will eventually lock to this maximum
31 and display a console message indicating this value.
33 Due to resource allocation issues in the Linux SCSI mid-layer, using
34 a high number of commands per device may result in memory allocation
35 failures when many devices are attached to the system. For this reason,
36 the default is set to 32. Higher values may result in higher performance
37 on some devices. The upper bound is 253. 0 disables tagged queueing.
39 Per device tag depth can be controlled via the kernel command line
40 "tag_info" option. See Documentation/scsi/aic7xxx.rst for details.
42 config AIC7XXX_RESET_DELAY_MS
43 int "Initial bus reset delay in milli-seconds"
44 depends on SCSI_AIC7XXX
47 The number of milliseconds to delay after an initial bus reset.
48 The bus settle delay following all error recovery actions is
49 dictated by the SCSI layer and is not affected by this value.
51 Default: 5000 (5 seconds)
53 config AIC7XXX_BUILD_FIRMWARE
54 bool "Build Adapter Firmware with Kernel Build"
55 depends on SCSI_AIC7XXX && !PREVENT_FIRMWARE_BUILD
57 This option should only be enabled if you are modifying the firmware
58 source to the aic7xxx driver and wish to have the generated firmware
59 include files updated during a normal kernel build. The assembler
60 for the firmware requires lex and yacc or their equivalents, as well
61 as the db v1 library. You may have to install additional packages
62 or modify the assembler Makefile or the files it includes if your
63 build environment is different than that of the author.
65 config AIC7XXX_DEBUG_ENABLE
66 bool "Compile in Debugging Code"
67 depends on SCSI_AIC7XXX
70 Compile in aic7xxx debugging code that can be useful in diagnosing
73 config AIC7XXX_DEBUG_MASK
74 int "Debug code enable mask (2047 for all debugging)"
75 depends on SCSI_AIC7XXX
78 Bit mask of debug options that is only valid if the
79 CONFIG_AIC7XXX_DEBUG_ENABLE option is enabled. The bits in this mask
80 are defined in the drivers/scsi/aic7xxx/aic7xxx.h - search for the
81 variable ahc_debug in that file to find them.
83 config AIC7XXX_REG_PRETTY_PRINT
84 bool "Decode registers during diagnostics"
85 depends on SCSI_AIC7XXX
88 Compile in register value tables for the output of expanded register
89 contents in diagnostics. This make it much easier to understand debug
90 output without having to refer to a data book and/or the aic7xxx.reg
