Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

5config SCSI_AIC7XXX
6 tristate "Adaptec AIC7xxx Fast -> U160 support (New Driver)"
7 depends on (PCI || EISA) && SCSI
8 ---help---
9 This driver supports all of Adaptec's Fast through Ultra 160 PCI
10 based SCSI controllers as well as the aic7770 based EISA and VLB
11 SCSI controllers (the 274x and 284x series). For AAA and ARO based
12 configurations, only SCSI functionality is provided.
13
14 To compile this driver as a module, choose M here: the
15 module will be called aic7xxx.
16
17config AIC7XXX_CMDS_PER_DEVICE
18 int "Maximum number of TCQ commands per device"
19 depends on SCSI_AIC7XXX
20 default "32"
21 ---help---
22 Specify the number of commands you would like to allocate per SCSI
23 device when Tagged Command Queueing (TCQ) is enabled on that device.
24
25 This is an upper bound value for the number of tagged transactions
26 to be used for any device. The aic7xxx driver will automatically
27 vary this number based on device behavior. For devices with a
28 fixed maximum, the driver will eventually lock to this maximum
29 and display a console message inidicating this value.
30
31 Due to resource allocation issues in the Linux SCSI mid-layer, using
32 a high number of commands per device may result in memory allocation
33 failures when many devices are attached to the system. For this reason,
34 the default is set to 32. Higher values may result in higer performance
35 on some devices. The upper bound is 253. 0 disables tagged queueing.
36
37 Per device tag depth can be controlled via the kernel command line
38 "tag_info" option. See drivers/scsi/aic7xxx/README.aic7xxx
39 for details.

41config AIC7XXX_RESET_DELAY_MS
42 int "Initial bus reset delay in milli-seconds"
43 depends on SCSI_AIC7XXX
44 default "15000"
45 ---help---
46 The number of milliseconds to delay after an initial bus reset.
47 The bus settle delay following all error recovery actions is
48 dictated by the SCSI layer and is not affected by this value.
49
50 Default: 15000 (15 seconds)
51
52config AIC7XXX_PROBE_EISA_VL
53 bool "Probe for EISA and VL AIC7XXX Adapters"
54 depends on SCSI_AIC7XXX && EISA
55 help
56 Probe for EISA and VLB Aic7xxx controllers. In many newer systems,
57 the invasive probes necessary to detect these controllers can cause
58 other devices to fail. For this reason, the non-PCI probe code is
59 disabled by default. The current value of this option can be "toggled"
60 via the no_probe kernel command line option.
61
62config AIC7XXX_BUILD_FIRMWARE
63 bool "Build Adapter Firmware with Kernel Build"
64 depends on SCSI_AIC7XXX && !PREVENT_FIRMWARE_BUILD
65 help
66 This option should only be enabled if you are modifying the firmware
67 source to the aic7xxx driver and wish to have the generated firmware
68 include files updated during a normal kernel build. The assembler
69 for the firmware requires lex and yacc or their equivalents, as well
70 as the db v1 library. You may have to install additional packages
71 or modify the assembler Makefile or the files it includes if your
72 build environment is different than that of the author.
73
74config AIC7XXX_DEBUG_ENABLE
75 bool "Compile in Debugging Code"
76 depends on SCSI_AIC7XXX
77 default y
78 help
79 Compile in aic7xxx debugging code that can be useful in diagnosing
80 driver errors.
81
82config AIC7XXX_DEBUG_MASK
83 int "Debug code enable mask (2047 for all debugging)"
84 depends on SCSI_AIC7XXX
85 default "0"
86 help
87 Bit mask of debug options that is only valid if the
88 CONFIG_AIC7XXX_DEBUG_ENBLE option is enabled. The bits in this mask
89 are defined in the drivers/scsi/aic7xxx/aic7xxx.h - search for the
90 variable ahc_debug in that file to find them.
91
92config AIC7XXX_REG_PRETTY_PRINT
93 bool "Decode registers during diagnostics"
94 depends on SCSI_AIC7XXX
95 default y
96 help
97 Compile in register value tables for the output of expanded register
98 contents in diagnostics. This make it much easier to understand debug
99 output without having to refer to a data book and/or the aic7xxx.reg
100 file.
