1This package requires flex, bison and qt to compile (actually it's
2possible without qt, but you'll miss most of the fun :) ).
3On most systems a simple 'make' should be enough, if you have qt
4installed in unusual location either set the QTDIR environment variable
5or issue 'make QTDIR=<path>'.
6
7'make install KERNELSRC=<path/to/linux/kernel> should be enough to
8install the package. The path must point to recent kernel sources,
9which will be converted to use this package. With 'make uninstall
10KERNELSRC=...' the package can be removed from the kernel again.
11
12lkc include a SWIG interface file. 'make ruby' builds a extension
13library for ruby in the .ruby dir.
14
15Have fun, Roman

576 + WARNING This driver is an older aic7xxx driver and is no longer
577 + under active development. Adaptec, Inc. is writing a new driver to
578 + take the place of this one, and it is recommended that whenever
579 + possible, people should use the new Adaptec written driver instead
580 + of this one. This driver will eventually be phased out entirely.
581+
582 + This is support for the various aic7xxx based Adaptec SCSI
583 + controllers. These include the 274x EISA cards; 284x VLB cards;
584 + 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
585 + motherboard based SCSI controllers from Adaptec. It does not support
586 + the AAA-13x RAID controllers from Adaptec, nor will it likely ever
587 + support them. It does not support the 2920 cards from Adaptec that
588 + use the Future Domain SCSI controller chip. For those cards, you
589 + need the "Future Domain 16xx SCSI support" driver.
590+
591 + In general, if the controller is based on an Adaptec SCSI controller
592 + chip from the aic777x series or the aic78xx series, this driver
593 + should work. The only exception is the 7810 which is specifically
594 + not supported (that's the RAID controller chip on the AAA-13x
595 + cards).
596+
597 + Note that the AHA2920 SCSI host adapter is *not* supported by this
598 + driver; choose "Future Domain 16xx SCSI support" instead if you have
599 + one of those.
600+
601 + Information on the configuration options for this controller can be
602 + found by checking the help file for each of the available
603 + configuration options. You should read
604 + <file:drivers/scsi/aic7xxx_old/README.aic7xxx> at a minimum before
605 + contacting the maintainer with any questions. The SCSI-HOWTO,
606 + available from <http://www.linuxdoc.org/docs.html#howto>, can also
607 + be of great help.
608+
609 + If you want to compile this driver as a module ( = code which can be
610 + inserted in and removed from the running kernel whenever you want),
611 + say M here and read <file:Documentation/modules.txt>. The module
612 + will be called aic7xxx_old.o.

1Introduction
2------------
3
4The configuration database is collection of configuration options
5organized in a tree structure:
6
7 +- Code maturity level options
8 | +- Prompt for development and/or incomplete code/drivers
9 +- General setup
10 | +- Networking support
11 | +- System V IPC
12 | +- BSD Process Accounting
13 | +- Sysctl support
14 +- Loadable module support
15 | +- Enable loadable module support
16 | +- Set version information on all module symbols
17 | +- Kernel module loader
18 +- ...
19
20Every entry has its own dependencies. These dependencies are used
21to determine the visible of an entry. Any child entry is only
22visible if its parent entry is also visible.
23
24Menu entries
25------------
26
27A single configuration option is defined like this:
28
29config MODVERSIONS
30 bool "Set version information on all module symbols"
31 depends MODULES
32 help
33 Usually, modules have to be recompiled whenever you switch to a new
34 kernel. ...
35
36Every line starts with a key word and can be followed by multiple arguments.
37"config" starts a new config entry. The following lines define attributes
38for this config option. Attributes can be the type of the config option,
39input prompt, dependencies, help text and default values. A config option
40can be defined multiple times, but every definition can have only a single
41input prompt and the type must not conflict.
42
43Menu dependencies
44-----------------
45
46Dependencies define the visibility of a menu entry. When a dependency
47exprecession evaluates not to 'n', the entry is visible. Additionally
48the dependency limits the input range of tristate choice symbols.
49
50Menu structure
51--------------
52
53The position of a menu entry in the tree is determined in two ways. First
54it can be specified explicitely:
55
56menu "Network device support"
57 depends NET
58
59config NETDEVICES
60 ...
61
62endmenu
63
64All entries within the "menu" ... "endmenu" block become a submenu of
65"Processor type and features". All subentries have the same dependencies
66than the menu entry, e.g. this means the dependency "NET" is added to the
67dependencies of the option NETDEVICES.
68The other way to generate the menu structure is done by analyzing the
69dependencies. If a menu entry somehow depends on the previous entry, it
70can be made a submenu of it.
71
72config MODULES
73 bool "Enable loadable module support"
74
75config MODVERSIONS
76 bool "Set version information on all module symbols"
77 depends MODULES
78
79comment "module support disabled"
80 depends !MODULES
81
82MODVERSIONS directly depends on MODULES, this means it's only visible if
83MODULES is different from 'n'. The comment on the other hand is always
84visible when MODULES it's visible (the dependency of MODULES are part
85of the comment dependencies).
86
87Menu attributes
88---------------
89
90A menu attribute can have a number of attributes. Not all of them are
91applicable everywhere (see spec).
92Input prompt: Every menu entry can have at most one menu entry, which
93is used to display to the user. An input prompt is either defined with
94"prompt" or it can be defined with the type.
95Type definition: Every config option must have a type, known types are
96currently: bool, tristate, string, hex, integer.
97Default value: It's possible to assign a config option a default value.
98This default is always used, when the option wasn't explicitly set by
99the user. This means it's either used as default value for input prompts
100or the value is saved to the kernel configuration. Multiple default
101values can be specified and every one has it's own dependencies. If
102multiple default values are visible, the first defined one is active.
103A default is not limited to a single menu entry, this means the default
104doesn't has to be defined with a input prompt, but it can also be
105overridden by prepend it with another definition.
106Dependencies: Dependencies can be either defined with "depends", then
107there are applied to all attributes of a menu entry, or attribute
108specific dependencies can be defined with "if", which immediately
109follows the attribute.

11. General Structure
2
3The configuration file describes a series of menu entries. These menu
4entries are organized in a tree structure. The following statements
5start a new menu entry definition (and end a previous menu entry):

152. Dependencies
16
17Every menu entry has dependencies, which define it's visibility in the
18menu structure. What makes these dependencies more difficult is that
19they use three states instead of two, that most programmers are familiar
20with. The additional 'mod' state is needed to describe drivers which
21are not compiled into the kernel, but are compiled as modules, which
22can be loaded at runtime. Nevertheless they should be straigthforward
23to use.
24Dependencies describe in first place the relation between configuration
25symbols and consequently between different parts of the kernel. To
26simplify the verification of the rule base, dependencies must be
27hierarchical, that means no recursive dependencies are allowed. The only
28possible non-hierarchical dependency are exclusions (aka choices), to
29cover typical uses during kernel configuration the semantic of choice
30statements has been extended (see the choice statement below).
31
32This allows to describe the following basic relationships:
33- initialization order of kernel subsystems. That means which other
34 subsystems are required (initialized and working), before a specific
35 subsystem can be initialized itself. This allows above requirement of
36 hierarchical dependencies.
37- mutual exclusions of kernel subsystems. This allows that only a single
38 of multiple possible subsystems is configured into the kernel.
39These are the same relationships, which are reasonably representable
40with cml1, but with this new config syntax it should be possible to
41easily add further relationships and other properties.
42
43The important usage of the dependency information is for generation of
44the menu structure. First it defines whether a symbol or statement is
45visible at all. If the dependency expression evaluates to 'n', the symbol
46is not visible (and is currently also not saved, this BTW corresponds to
47the behavior of xconfig, which is noted as a bug in Documentation/
48kbuild/config-language.txt, that didn't seem to be a problem so far, but
49that has to be considered).
50If a symbol is visible, it defines the possible input range for tristate
51symbols, if the dependency expression evaluates to 'm', a tristate symbol
52can only be set to 'n' or 'm', otherwise also 'y' is possible.
53Finally dependency information is also used to group symbols together.
54If a symbol entry is followed by other symbol entries which depends on
55the first one, the latter entries are associated with the first entry.
56The text config front end uses this information to automatically indent
57the entries, the qt interface creates further submenus. This can reduce
58the amount of explicit menu information required.
59
60syntax:
61
62This is the syntax of dependency expressions:
63
64 <expr> ::= <symbol> (1)
65 <symbol> '=' <symbol> (2)
66 <symbol> '!=' <symbol> (3)
67 '(' <expr> ')' (4)
68 '!' <expr> (5)
69 <expr> '||' <expr> (6)
70 <expr> '&&' <expr> (7)
71
72Expressions are listed in decreasing order of precedence. An
73expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 respectively
74for calculations below).
75There are two type of symbols: constant and nonconstant symbols.
76Nonconstant symbols are the most common ones and are defined with the
77'config' statement. Nonconstant symbols consist entirely of alphanumeric
78characters or underscores.
79Constant symbols are only part of expressions. Constant symbols are
80always surrounded by single or double quotes. Within the quote any
81other character is allowed and the quotes can be escaped using '\'.
82Nonconstant symbols which are nowhere defined with 'config' are a
83special case, they behave like constant symbols, so that one can do
84"FOO=123", it usage should restricted to number values (this might
85be enforced later).
86
87expression syntax:
88
89(1) Convert the symbol into an expression. Boolean and tristate symbols
90 are simply converted into the respective expression values. All other
91 symbol types result in 'n'.
92(2) If the values of both symbols are equal, it returns 'y', otherwise 'n'.
93(3) If the values of both symbols are equal, it returns 'n', otherwise 'y'.
94(4) Returns the value of the expression. Used to override precedence.
95(5) Returns the result of (2-/expr/).
96(6) Returns the result of min(/expr/, /expr/).
97(7) Returns the result of max(/expr/, /expr/).
98
993. "config"
100
101syntax:
102
103 "config" <symbol>
104 <config options>
105
106Defines a new config symbol. A symbol can be defined multiple times as
107long as the symbol type is always the same.
108
109config options:
110
111 "depends" <expr>
112
113defines the visibility and the input range of the config symbol.
114
115 "tristate" <prompt> "if" <expr>
116 "bool" <prompt> "if" <expr>
117 "int" <prompt> "if" <expr>
118 "hex" <prompt> "if" <expr>
119 "string" <prompt> "if" <expr>
120
121defines the type of the symbol and the prompt which is used to request a
122value from the user. Additional constraints for the visibility and the
123input range of the prompt can be defined after an "if" statement. The
124prompt and the "if" statement are optional, but an "if" statement
125without a prompt is not possible.
126
127 "prompt" <prompt> "if" <expr>
128
129same as above, but without defining the type of the symbol. This was
130generated by earlier versions of the converter and will likely
131disappear unless needed otherwise.
132
133 "default" <symbol> "if" <expr>
134
135defines a default value for the config symbol. Unless the config symbol
136was previously set by the user, it will set to this value. This means
137it will be used as default value for above input prompts or if no user
138prompt is visible the config symbol will be saved with this value. If
139multiple default statements are visible only the first is used.
140
141 "help"
142
143defines a help text for this statement. The end of the help text
144is determined by the level indentation, this means it ends at the first
145line which has a smaller indentation than the first line of the help text.
146
1474. "choice"
148
149syntax:
150
151 "choice"
152 <choice options>
153 <choice block>
154 "endchoice"
155
156defines a group of related config statements. There are two types of
157choice statements - bool and tristate.
158
159bool choice: allows only single config statement to be selected and
160set to "y".
161tristate choice: extends the bool choice by also allowing multiple
162config statement to be selected, but in this mode these will only be set
163"m". This can be used if multiple drivers for a single hardware exists
164and only a single driver can be compiled/loaded into the kernel, but all
165drivers can be compiled as modules.
166
167choice options:
168
169 "depends" <expr>
170
171defines the visibility and the input range of the choice.
172
173 "prompt" <prompt>
174
175defines the prompt which is presented to the user.
176
177 <optional>
178
179by default exactly one of the config statements of a bool choice has
180to be selected, this option allows that also no config statement has to
181be selected.
182
183 "default" <symbol>
184
185defines the default choice presented to the user. The prompt must be a
186one of symbols defined within this choice.
187
188 "help"
189
190defines a help text for this choice statement. The end of the help text
191is determined by the level indentation, this means it ends at the first
192line which has a smaller indentation than the first line of the help text.
193
194choice block:
195
196right now only config statements allowed. (It's possible to also allow
197other statements later.)
198
1995. "comment"
200
201syntax:
202
203 "comment" <prompt>
204 <comment options>
205
206defines the prompt which is displayed to the user during the
207configuration process and is also echoes it to the output files during
208output.
209
210comment options:
211
212 "depends" <expr>
213
214defines the visibility of the comment.
215
2166. "menu"
217
218syntax:
219
220 "menu" <prompt>
221 <menu options>
222 <menu block>
223 "endmenu"
224
225menu options:
226
227 "depends" <expr>
228
229defines the visibility of the menu.
230
231menu block:
232
233Any of the basic statements is allowed within a menu block.
234
2357. "if"
236
237syntax:
238
239 "if" <expr>
240 <if block>
241 "endif"
242
2438. "source"
244
245syntax:
246
247 "source" <prompt>
248
249reads the specified configuration file. this is done unconditionally,
