charset="utf-8" Content-Transfer-Encoding: quoted-printable Errors-To: xen-devel-bounces@lists.xenproject.org Sender: "Xen-devel" X-ZohoMail-DKIM: fail (Header signature does not verify) This patch updates Kconfig to a more recent version of Kconfig, found in Linux v5.4.0, 219d54332a09 ("Linux 5.4"). With the updated version of Kconfig, other changes are necessary to avoid breaking the build. Kconfig files: - fix Kconfig files that where using option env=3D*: Since Linux commit 104daea149c4 ("kconfig: reference environment variables directly and remove 'option env=3D'"), we can access the environment directly via $() and "option env=3D" as been removed. - CONFIG_EXPERT=3D'y' will now appear in .config file if XEN_CONFIG_EXPERT=3Dy in the environment. The alternative is to change "EXPERT" to "$(XEN_CONFIG_EXPERT)" in all Kconfig files. Makefile: - silentoldconfig target as been removed from Kconfig. To update include/generated/autoconf.h, we need to use syncconfig target instead. Makefile.kconfig: - Import newer needed code from Linux's Makefile.lib and Kbuild.include and Makefile.build. - Set Q to empty, Xen build system doesn't silence commands. Having Q empty mean we can import stuff from Linux without having to remove the leading $(Q) from build commands. And quiet=3D'' means commands will be echoed. - Add $(PHONY) to .PHONY. Like it is intended by Kbuild. Makefile.host is also updated and copied from Linux. Dependency change: - Now depends on flex/bison, maybe we could _shipped those files like before. Linux doesn't do that anymore.

+The configuration database is a collection of configuration options +organized in a tree structure:: + + +- Code maturity level options + | +- Prompt for development and/or incomplete code/drivers + +- General setup + | +- Networking support + | +- System V IPC + | +- BSD Process Accounting + | +- Sysctl support + +- Loadable module support + | +- Enable loadable module support + | +- Set version information on all module symbols + | +- Kernel module loader + +- ... + +Every entry has its own dependencies. These dependencies are used +to determine the visibility of an entry. Any child entry is only +visible if its parent entry is also visible. + +Menu entries +------------ + +Most entries define a config option; all other entries help to organize +them. A single configuration option is defined like this:: + + config MODVERSIONS + bool "Set version information on all module symbols" + depends on MODULES + help + Usually, modules have to be recompiled whenever you switch to a new + kernel. ... + +Every line starts with a key word and can be followed by multiple +arguments. "config" starts a new config entry. The following lines +define attributes for this config option. Attributes can be the type of +the config option, input prompt, dependencies, help text and default +values. A config option can be defined multiple times with the same +name, but every definition can have only a single input prompt and the +type must not conflict. + +Menu attributes +--------------- + +A menu entry can have a number of attributes. Not all of them are +applicable everywhere (see syntax). + +- type definition: "bool"/"tristate"/"string"/"hex"/"int" + + Every config option must have a type. There are only two basic types: + tristate and string; the other types are based on these two. The type + definition optionally accepts an input prompt, so these two examples + are equivalent:: + + bool "Networking support" + + and:: + + bool + prompt "Networking support" + +- input prompt: "prompt" ["if" ] + + Every menu entry can have at most one prompt, which is used to display + to the user. Optionally dependencies only for this prompt can be added + with "if". + +- default value: "default" ["if" ] + + A config option can have any number of default values. If multiple + default values are visible, only the first defined one is active. + Default values are not limited to the menu entry where they are + defined. This means the default can be defined somewhere else or be + overridden by an earlier definition. + The default value is only assigned to the config symbol if no other + value was set by the user (via the input prompt above). If an input + prompt is visible the default value is presented to the user and can + be overridden by him. + Optionally, dependencies only for this default value can be added with + "if". + + The default value deliberately defaults to 'n' in order to avoid bloating= the + build. With few exceptions, new config options should not change this. The + intent is for "make oldconfig" to add as little as possible to the config= from + release to release. + + Note: + Things that merit "default y/m" include: + + a) A new Kconfig option for something that used to always be built + should be "default y". + + b) A new gatekeeping Kconfig option that hides/shows other Kconfig + options (but does not generate any code of its own), should be + "default y" so people will see those other options. + + c) Sub-driver behavior or similar options for a driver that is + "default n". This allows you to provide sane defaults. + + d) Hardware or infrastructure that everybody expects, such as CONFIG_NET + or CONFIG_BLOCK. These are rare exceptions. + +- type definition + default value:: + + "def_bool"/"def_tristate" ["if" ] + + This is a shorthand notation for a type definition plus a value. + Optionally dependencies for this default value can be added with "if". + +- dependencies: "depends on" + + This defines a dependency for this menu entry. If multiple + dependencies are defined, they are connected with '&&'.

Used for symbols that hide other symbols. + +Menu dependencies +----------------- + +Dependencies define the visibility of a menu entry and can also reduce +the input range of tristate symbols. The tristate logic used in the +expressions uses one more state than normal boolean logic to express the +module state. Dependency expressions have the following syntax:: + + ::=3D (1) + '=3D' (2) + '!=3D' (3) + '<' (4) + '>' (4) + '<=3D' (4) + '>=3D' (4) + '(' ')' (5) + '!'

Used to override precedence. +(6) Returns the result of (2-/expr/). +(7) Returns the result of min(/expr/, /expr/). +(8) Returns the result of max(/expr/, /expr/). + +An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 +respectively for calculations). A menu entry becomes visible when its +expression evaluates to 'm' or 'y'. + +There are two types of symbols: constant and non-constant symbols. +Non-constant symbols are the most common ones and are defined with the +'config' statement. Non-constant symbols consist entirely of alphanumeric +characters or underscores. +Constant symbols are only part of expressions. Constant symbols are +always surrounded by single or double quotes. Within the quote, any +other character is allowed and the quotes can be escaped using '\'. + +Menu structure +-------------- + +The position of a menu entry in the tree is determined in two ways. First +it can be specified explicitly:: + + menu "Network device support" + depends on NET + + config NETDEVICES + ... + + endmenu + +All entries within the "menu" ... "endmenu" block become a submenu of +"Network device support". All subentries inherit the dependencies from +the menu entry, e.g. this means the dependency "NET" is added to the +dependency list of the config option NETDEVICES. + +The other way to generate the menu structure is done by analyzing the +dependencies. If a menu entry somehow depends on the previous entry, it +can be made a submenu of it. First, the previous (parent) symbol must +be part of the dependency list and then one of these two conditions +must be true: + +- the child entry must become invisible, if the parent is set to 'n' +- the child entry must only be visible, if the parent is visible:: + + config MODULES + bool "Enable loadable module support" + + config MODVERSIONS + bool "Set version information on all module symbols" + depends on MODULES + + comment "module support disabled" + depends on !MODULES + +MODVERSIONS directly depends on MODULES, this means it's only visible if +MODULES is different from 'n'. The comment on the other hand is only +visible when MODULES is set to 'n'. + + +Kconfig syntax +-------------- + +The configuration file describes a series of menu entries, where every +line starts with a keyword (except help texts). The following keywords +end a menu entry: + +- config +- menuconfig +- choice/endchoice +- comment +- menu/endmenu +- if/endif +- source + +The first five also start the definition of a menu entry. + +config:: + + "config" + + +This defines a config symbol and accepts any of above +attributes as options. + +menuconfig:: + + "menuconfig" + + +This is similar to the simple config entry above, but it also gives a +hint to front ends, that all suboptions should be displayed as a +separate list of options. To make sure all the suboptions will really +show up under the menuconfig entry and not outside of it, every item +from the list must depend on the menuconfig symbol. +In practice, this is achieved by using one of the next two constructs:: + + (1): + menuconfig M + if M + config C1 + config C2 + endif + + (2): + menuconfig M + config C1 + depends on M + config C2 + depends on M + +In the following examples (3) and (4), C1 and C2 still have the M +dependency, but will not appear under menuconfig M anymore, because +of C0, which doesn't depend on M:: + + (3): + menuconfig M + config C0 + if M + config C1 + config C2 + endif + + (4): + menuconfig M + config C0 + config C1 + depends on M + config C2 + depends on M + +choices:: + + "choice" [symbol] + + + "endchoice" + +This defines a choice group and accepts any of the above attributes as +options. A choice can only be of type bool or tristate. If no type is +specified for a choice, its type will be determined by the type of +the first choice element in the group or remain unknown if none of the +choice elements have a type specified, as well. + +While a boolean choice only allows a single config entry to be +selected, a tristate choice also allows any number of config entries +to be set to 'm'. This can be used if multiple drivers for a single +hardware exists and only a single driver can be compiled/loaded into +the kernel, but all drivers can be compiled as modules. + +A choice accepts another option "optional", which allows to set the +choice to 'n' and no entry needs to be selected. +If no [symbol] is associated with a choice, then you can not have multiple +definitions of that choice. If a [symbol] is associated to the choice, +then you may define the same choice (i.e. with the same entries) in another +place. + +comment:: + + "comment" + + +This defines a comment which is displayed to the user during the +configuration process and is also echoed to the output files. The only +possible options are dependencies. + +menu:: + + "menu" + + + "endmenu" + +This defines a menu block, see "Menu structure" above for more +information. The only possible options are dependencies and "visible" +attributes. + +if:: + + "if" + + "endif" + +This defines an if block. The dependency expression is appended +to all enclosed menu entries. + +source:: + + "source" + +This reads the specified configuration file. This file is always parsed. + +mainmenu:: + + "mainmenu" + +This sets the config program's title bar if the config program chooses +to use it. It should be placed at the top of the configuration, before any +other statement. + +'#' Kconfig source file comment: + +An unquoted '#' character anywhere in a source file line indicates +the beginning of a source file comment. The remainder of that line +is a comment. + + +Kconfig hints +------------- +This is a collection of Kconfig tips, most of which aren't obvious at +first glance and most of which have become idioms in several Kconfig +files. + +Adding common features and make the usage configurable +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +It is a common idiom to implement a feature/functionality that are +relevant for some architectures but not all. +The recommended way to do so is to use a config variable named HAVE_* +that is defined in a common Kconfig file and selected by the relevant +architectures. +An example is the generic IOMAP functionality. + +We would in lib/Kconfig see:: + + # Generic IOMAP is used to ... + config HAVE_GENERIC_IOMAP + + config GENERIC_IOMAP + depends on HAVE_GENERIC_IOMAP && FOO + +And in lib/Makefile we would see:: + + obj-$(CONFIG_GENERIC_IOMAP) +=3D iomap.o + +For each architecture using the generic IOMAP functionality we would see:: + + config X86 + select ... + select HAVE_GENERIC_IOMAP + select ... + +Note: we use the existing config option and avoid creating a new +config variable to select HAVE_GENERIC_IOMAP. + +Note: the use of the internal config variable HAVE_GENERIC_IOMAP, it is +introduced to overcome the limitation of select which will force a +config option to 'y' no matter the dependencies. +The dependencies are moved to the symbol GENERIC_IOMAP and we avoid the +situation where select forces a symbol equals to 'y'. + +Adding features that need compiler support +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +There are several features that need compiler support. The recommended way +to describe the dependency on the compiler feature is to use "depends on" +followed by a test macro:: + + config STACKPROTECTOR + bool "Stack Protector buffer overflow detection" + depends on $(cc-option,-fstack-protector) + ... + +If you need to expose a compiler capability to makefiles and/or C source f= iles, +`CC_HAS_` is the recommended prefix for the config option:: + + config CC_HAS_STACKPROTECTOR_NONE + def_bool $(cc-option,-fno-stack-protector) + +Build as module only +~~~~~~~~~~~~~~~~~~~~ +To restrict a component build to module-only, qualify its config symbol +with "depends on m". E.g.:: + + config FOO + depends on BAR && m + +limits FOO to module (=3Dm) or disabled (=3Dn). + +Kconfig recursive dependency limitations +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If you've hit the Kconfig error: "recursive dependency detected" you've run +into a recursive dependency issue with Kconfig, a recursive dependency can= be +summarized as a circular dependency. The kconfig tools need to ensure that +Kconfig files comply with specified configuration requirements. In order t= o do +that kconfig must determine the values that are possible for all Kconfig +symbols, this is currently not possible if there is a circular relation +between two or more Kconfig symbols. For more details refer to the "Simple +Kconfig recursive issue" subsection below. Kconfig does not do recursive +dependency resolution; this has a few implications for Kconfig file writer= s. +We'll first explain why this issues exists and then provide an example +technical limitation which this brings upon Kconfig developers.

A full SAT solver can be +desirable to enable more complex dependency mappings and / or queries, +for instance on possible use case for a SAT solver could be that of handli= ng +the current known recursive dependency issues. It is not known if this wou= ld +address such issues but such evaluation is desirable. If support for a ful= l SAT +solver proves too complex or that it cannot address recursive dependency i= ssues +Kconfig should have at least clear and well defined semantics which also +addresses and documents limitations or requirements such as the ones deali= ng +with recursive dependencies. + +Further work on both of these areas is welcomed on Kconfig. We elaborate +on both of these in the next two subsections. + +Semantics of Kconfig +~~~~~~~~~~~~~~~~~~~~ + +The use of Kconfig is broad, Linux is now only one of Kconfig's users: +one study has completed a broad analysis of Kconfig use in 12 projects [0]= _. +Despite its widespread use, and although this document does a reasonable j= ob +in documenting basic Kconfig syntax a more precise definition of Kconfig +semantics is welcomed. One project deduced Kconfig semantics through +the use of the xconfig configurator [1]_. Work should be done to confirm if +the deduced semantics matches our intended Kconfig design goals. + +Having well defined semantics can be useful for tools for practical +evaluation of depenencies, for instance one such use known case was work to +express in boolean abstraction of the inferred semantics of Kconfig to +translate Kconfig logic into boolean formulas and run a SAT solver on this= to +find dead code / features (always inactive), 114 dead features were found = in +Linux using this methodology [1]_ (Section 8: Threats to validity). + +Confirming this could prove useful as Kconfig stands as one of the the lea= ding +industrial variability modeling languages [1]_ [2]_. Its study would help +evaluate practical uses of such languages, their use was only theoretical +and real world requirements were not well understood. As it stands though +only reverse engineering techniques have been used to deduce semantics from +variability modeling languages such as Kconfig [3]_. + +..

[3] http://gsd.uwaterloo.ca/sites/default/files/icse2011.pdf + +Full SAT solver for Kconfig +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Although SAT solvers [4]_ haven't yet been used by Kconfig directly, as no= ted +in the previous subsection, work has been done however to express in boole= an +abstraction the inferred semantics of Kconfig to translate Kconfig logic i= nto +boolean formulas and run a SAT solver on it [5]_. Another known related pr= oject +is CADOS [6]_ (former VAMOS [7]_) and the tools, mainly undertaker [8]_, w= hich +has been introduced first with [9]_. The basic concept of undertaker is to +exract variability models from Kconfig, and put them together with a +propositional formula extracted from CPP #ifdefs and build-rules into a SAT +solver in order to find dead code, dead files, and dead symbols. If using = a SAT +solver is desirable on Kconfig one approach would be to evaluate repurposi= ng +such efforts somehow on Kconfig.

A choice can only be of type bool or tristate, while a boolean -choice only allows a single config entry to be selected, a tristate -choice also allows any number of config entries to be set to 'm'. This -can be used if multiple drivers for a single hardware exists and only a -single driver can be compiled/loaded into the kernel, but all drivers -can be compiled as modules. -A choice accepts another option "optional", which allows to set the -choice to 'n' and no entry needs to be selected. -If no [symbol] is associated with a choice, then you can not have multiple -definitions of that choice. If a [symbol] is associated to the choice, -then you may define the same choice (ie. with the same entries) in another -place. - -comment: - - "comment" - - -This defines a comment which is displayed to the user during the -configuration process and is also echoed to the output files. The only -possible options are dependencies. - -menu: - - "menu" - - - "endmenu" - -This defines a menu block, see "Menu structure" above for more -information. The only possible options are dependencies and "visible" -attributes. - -if: - - "if" - - "endif" - -This defines an if block.

When we look at Make, we notice sort = of +two languages in one. One language describes dependency graphs consisting = of +targets and prerequisites. The other is a macro language for performing te= xtual +substitution. + +There is clear distinction between the two language stages. For example, y= ou +can write a makefile like follows:: + + APP :=3D foo + SRC :=3D foo.c + CC :=3D gcc + + $(APP): $(SRC) + $(CC) -o $(APP) $(SRC) + +The macro language replaces the variable references with their expanded fo= rm, +and handles as if the source file were input like follows:: + + foo: foo.c + gcc -o foo foo.c + +Then, Make analyzes the dependency graph and determines the targets to be +updated. + +The idea is quite similar in Kconfig - it is possible to describe a Kconfig +file like this:: + + CC :=3D gcc + + config CC_HAS_FOO + def_bool $(shell, $(srctree)/scripts/gcc-check-foo.sh $(CC)) + +The macro language in Kconfig processes the source file into the following +intermediate:: + + config CC_HAS_FOO + def_bool y + +Then, Kconfig moves onto the evaluation stage to resolve inter-symbol +dependency as explained in kconfig-language.txt. + + +Variables +--------- + +Like in Make, a variable in Kconfig works as a macro variable. A macro +variable is expanded "in place" to yield a text string that may then be +expanded further. To get the value of a variable, enclose the variable nam= e in +$( ). The parentheses are required even for single-letter variable names; = $X is +a syntax error. The curly brace form as in ${CC} is not supported either. + +There are two types of variables: simply expanded variables and recursively +expanded variables. + +A simply expanded variable is defined using the :=3D assignment operator. = Its +righthand side is expanded immediately upon reading the line from the Kcon= fig +file. + +A recursively expanded variable is defined using the =3D assignment operat= or. +Its righthand side is simply stored as the value of the variable without +expanding it in any way. Instead, the expansion is performed when the vari= able +is used. + +There is another type of assignment operator; +=3D is used to append text = to a +variable. The righthand side of +=3D is expanded immediately if the leftha= nd +side was originally defined as a simple variable. Otherwise, its evaluatio= n is +deferred. + +The variable reference can take parameters, in the following form:: + + $(name,arg1,arg2,arg3) + +You can consider the parameterized reference as a function. (more precisel= y, +"user-defined function" in contrast to "built-in function" listed below). + +Useful functions must be expanded when they are used since the same functi= on is +expanded differently if different parameters are passed. Hence, a user-def= ined +function is defined using the =3D assignment operator. The parameters are +referenced within the body definition with $(1), $(2), etc. + +In fact, recursively expanded variables and user-defined functions are the= same +internally. (In other words, "variable" is "function with zero argument".) +When we say "variable" in a broad sense, it includes "user-defined functio= n". + + +Built-in functions +------------------ + +Like Make, Kconfig provides several built-in functions. Every function tak= es a +particular number of arguments. + +In Make, every built-in function takes at least one argument. Kconfig allo= ws +zero argument for built-in functions, such as $(fileno), $(lineno). You co= uld +consider those as "built-in variable", but it is just a matter of how we c= all +it after all. Let's say "built-in function" here to refer to natively supp= orted +functionality. + +Kconfig currently supports the following built-in functions. + + - $(shell,command) + + The "shell" function accepts a single argument that is expanded and pass= ed + to a subshell for execution. The standard output of the command is then = read + and returned as the value of the function. Every newline in the output is + replaced with a space. Any trailing newlines are deleted. The standard e= rror + is not returned, nor is any program exit status. + + - $(info,text) + + The "info" function takes a single argument and prints it to stdout. + It evaluates to an empty string. + + - $(warning-if,condition,text) + + The "warning-if" function takes two arguments. If the condition part is = "y", + the text part is sent to stderr. The text is prefixed with the name of t= he + current Kconfig file and the current line number. + + - $(error-if,condition,text) + + The "error-if" function is similar to "warning-if", but it terminates the + parsing immediately if the condition part is "y". + + - $(filename) + + The 'filename' takes no argument, and $(filename) is expanded to the file + name being parsed. + + - $(lineno) + + The 'lineno' takes no argument, and $(lineno) is expanded to the line nu= mber + being parsed. + + +Make vs Kconfig +--------------- + +Kconfig adopts Make-like macro language, but the function call syntax is +slightly different. + +A function call in Make looks like this:: + + $(func-name arg1,arg2,arg3) + +The function name and the first argument are separated by at least one +whitespace. Then, leading whitespaces are trimmed from the first argument, +while whitespaces in the other arguments are kept. You need to use a kind = of +trick to start the first parameter with spaces. For example, if you want +to make "info" function print " hello", you can write like follows:: + + empty :=3D + space :=3D $(empty) $(empty) + $(info $(space)$(space)hello) + +Kconfig uses only commas for delimiters, and keeps all whitespaces in the +function call. Some people prefer putting a space after each comma delimit= er:: + + $(func-name, arg1, arg2, arg3) + +In this case, "func-name" will receive " arg1", " arg2", " arg3". The pres= ence +of leading spaces may matter depending on the function. The same applies to +Make - for example, $(subst .c, .o, $(sources)) is a typical mistake; it +replaces ".c" with " .o". + +In Make, a user-defined function is referenced by using a built-in functio= n, +'call', like this:: + + $(call my-func,arg1,arg2,arg3) + +Kconfig invokes user-defined functions and built-in functions in the same = way. +The omission of 'call' makes the syntax shorter. + +In Make, some functions treat commas verbatim instead of argument separato= rs. +For example, $(shell echo hello, world) runs the command "echo hello, worl= d". +Likewise, $(info hello, world) prints "hello, world" to stdout. You could = say +this is _useful_ inconsistency. + +In Kconfig, for simpler implementation and grammatical consistency, commas= that +appear in the $( ) context are always delimiters. It means:: + + $(shell, echo hello, world) + +is an error because it is passing two parameters where the 'shell' function +accepts only one. To pass commas in arguments, you can use the following t= rick:: + + comma :=3D , + $(shell, echo hello$(comma) world) + + +Caveats +------- + +A variable (or function) cannot be expanded across tokens. So, you cannot = use +a variable as a shorthand for an expression that consists of multiple toke= ns. +The following works:: + + RANGE_MIN :=3D 1 + RANGE_MAX :=3D 3 + + config FOO + int "foo" + range $(RANGE_MIN) $(RANGE_MAX) + +But, the following does not work:: + + RANGES :=3D 1 3 + + config FOO + int "foo" + range $(RANGES) + +A variable cannot be expanded to any keyword in Kconfig.

We won't be able to include Config.mk so we will need a replacement for the macro `cc-ifversion'. This patch imports parts of "scripts/Kbuild.include" from Linux v5.4, the macro cc-ifversion. It makes use of CONFIG_GCC_VERSION that Kconfig now provides. Since they are no other use of Xen's `cc-ifversion' macro, we can remove it.
