Convert everything to ReST without affecting too much the author's style and avoiding adding uneeded markups. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings.

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:: + + ::= (1) + '=' (2) + '!=' (3) + '<' (4) + '>' (4) + '<=' (4) + '>=' (4) + '(' ')' (5) + '!' (6) + '&&' (7) + '||' (8) + +Expressions are listed in decreasing order of precedence. + +(1) Convert the symbol into an expression. Boolean and tristate symbols + are simply converted into the respective expression values. All + other symbol types result in 'n'. +(2) If the values of both symbols are equal, it returns 'y', + otherwise 'n'. +(3) If the values of both symbols are equal, it returns 'n', + otherwise 'y'. +(4) If value of is respectively lower, greater, lower-or-equal, + or greater-or-equal than value of , it returns 'y', + otherwise 'n'. +(5) Returns the value of the expression. 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) += 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 files, +`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 (=m) or disabled (=n). + +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 to 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 writers. +We'll first explain why this issues exists and then provide an example +technical limitation which this brings upon Kconfig developers. Eager +developers wishing to try to address this limitation should read the next +subsections. + +Simple Kconfig recursive issue +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Read: Documentation/kbuild/Kconfig.recursion-issue-01 + +Test with:: + + make KBUILD_KCONFIG=Documentation/kbuild/Kconfig.recursion-issue-01 allnoconfig + +Cumulative Kconfig recursive issue +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Read: Documentation/kbuild/Kconfig.recursion-issue-02 + +Test with:: + + make KBUILD_KCONFIG=Documentation/kbuild/Kconfig.recursion-issue-02 allnoconfig + +Practical solutions to kconfig recursive issue +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Developers who run into the recursive Kconfig issue have two options +at their disposal. We document them below and also provide a list of +historical issues resolved through these different solutions. + + a) Remove any superfluous "select FOO" or "depends on FOO" + b) Match dependency semantics: + + b1) Swap all "select FOO" to "depends on FOO" or, + + b2) Swap all "depends on FOO" to "select FOO" + +The resolution to a) can be tested with the sample Kconfig file +Documentation/kbuild/Kconfig.recursion-issue-01 through the removal +of the "select CORE" from CORE_BELL_A_ADVANCED as that is implicit already +since CORE_BELL_A depends on CORE. At times it may not be possible to remove +some dependency criteria, for such cases you can work with solution b). + +The two different resolutions for b) can be tested in the sample Kconfig file +Documentation/kbuild/Kconfig.recursion-issue-02. + +Below is a list of examples of prior fixes for these types of recursive issues; +all errors appear to involve one or more select's and one or more "depends on". + +============ =================================== +commit fix +============ =================================== +06b718c01208 select A -> depends on A +c22eacfe82f9 depends on A -> depends on B +6a91e854442c select A -> depends on A +118c565a8f2e select A -> select B +f004e5594705 select A -> depends on A +c7861f37b4c6 depends on A -> (null) +80c69915e5fb select A -> (null) (1) +c2218e26c0d0 select A -> depends on A (1) +d6ae99d04e1c select A -> depends on A +95ca19cf8cbf select A -> depends on A +8f057d7bca54 depends on A -> (null) +8f057d7bca54 depends on A -> select A +a0701f04846e select A -> depends on A +0c8b92f7f259 depends on A -> (null) +e4e9e0540928 select A -> depends on A (2) +7453ea886e87 depends on A > (null) (1) +7b1fff7e4fdf select A -> depends on A +86c747d2a4f0 select A -> depends on A +d9f9ab51e55e select A -> depends on A +0c51a4d8abd6 depends on A -> select A (3) +e98062ed6dc4 select A -> depends on A (3) +91e5d284a7f1 select A -> (null) +============ =================================== + +(1) Partial (or no) quote of error. +(2) That seems to be the gist of that fix. +(3) Same error. + +Future kconfig work +~~~~~~~~~~~~~~~~~~~ + +Work on kconfig is welcomed on both areas of clarifying semantics and on +evaluating the use of a full SAT solver for it. 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 handling +the current known recursive dependency issues. It is not known if this would +address such issues but such evaluation is desirable. If support for a full SAT +solver proves too complex or that it cannot address recursive dependency issues +Kconfig should have at least clear and well defined semantics which also +addresses and documents limitations or requirements such as the ones dealing +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 job +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 leading +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 noted +in the previous subsection, work has been done however to express in boolean +abstraction the inferred semantics of Kconfig to translate Kconfig logic into +boolean formulas and run a SAT solver on it [5]_. Another known related project +is CADOS [6]_ (former VAMOS [7]_) and the tools, mainly undertaker [8]_, which +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 repurposing +such efforts somehow on Kconfig. There is enough interest from mentors of +existing projects to not only help advise how to integrate this work upstream +but also help maintain it long term.

These options are currently possible: - - - "defconfig_list" - This declares a list of default entries which can be used when - looking for the default configuration (which is used when the main - .config doesn't exists yet.) - - - "modules" - This declares the symbol to be used as the MODULES symbol, which - enables the third modular state for all config symbols. - At most one symbol may have the "modules" option set. - - - "allnoconfig_y" - This declares the symbol as one that should have the value y when - using "allnoconfig". 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: - - ::= (1) - '=' (2) - '!=' (3) - '<' (4) - '>' (4) - '<=' (4) - '>=' (4) - '(' ')' (5) - '!' (6) - '&&' (7) - '||' (8) - -Expressions are listed in decreasing order of precedence. - -(1) Convert the symbol into an expression. Boolean and tristate symbols - are simply converted into the respective expression values. All - other symbol types result in 'n'. -(2) If the values of both symbols are equal, it returns 'y', - otherwise 'n'. -(3) If the values of both symbols are equal, it returns 'n', - otherwise 'y'. -(4) If value of is respectively lower, greater, lower-or-equal, - or greater-or-equal than value of , it returns 'y', - otherwise 'n'. -(5) Returns the value of the expression. 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) += 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 files, -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 (=m) or disabled (=n). - -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 to 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 writers. -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 handling -the current known recursive dependency issues. It is not known if this would -address such issues but such evaluation is desirable. If support for a full SAT -solver proves too complex or that it cannot address recursive dependency issues -Kconfig should have at least clear and well defined semantics which also -addresses and documents limitations or requirements such as the ones dealing -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 job -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 leading -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]. - -[0] http://www.eng.uwaterloo.ca/~shshe/kconfig_semantics.pdf -[1] http://gsd.uwaterloo.ca/sites/default/files/vm-2013-berger.pdf -[2] http://gsd.uwaterloo.ca/sites/default/files/ase241-berger_0.pdf -[3] http://gsd.uwaterloo.ca/sites/default/files/icse2011.pdf - -Full SAT solver for Kconfig -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Although SAT solvers [0] haven't yet been used by Kconfig directly, as noted in -the previous subsection, work has been done however to express in boolean -abstraction the inferred semantics of Kconfig to translate Kconfig logic into -boolean formulas and run a SAT solver on it [1]. Another known related project -is CADOS [2] (former VAMOS [3]) and the tools, mainly undertaker [4], which has -been introduced first with [5]. 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 repurposing such efforts -somehow on Kconfig. There is enough interest from mentors of existing projects -to not only help advise how to integrate this work upstream but also help -maintain it long term.

Every function takes a +particular number of arguments. + +In Make, every built-in function takes at least one argument. Kconfig allows +zero argument for built-in functions, such as $(fileno), $(lineno). You could +consider those as "built-in variable", but it is just a matter of how we call +it after all. Let's say "built-in function" here to refer to natively supported +functionality. + +Kconfig currently supports the following built-in functions. + + - $(shell,command) + + The "shell" function accepts a single argument that is expanded and passed + to a subshell for execution.

If the condition part is "y", + the text part is sent to stderr. The text is prefixed with the name of the + 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 number + 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 := + space := $(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 delimiter:: + + $(func-name, arg1, arg2, arg3) + +In this case, "func-name" will receive " arg1", " arg2", " arg3". The presence +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 function, +'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 separators. +For example, $(shell echo hello, world) runs the command "echo hello, world". +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 trick:: + + comma := , + $(shell, echo hello$(comma) world) + + +Caveats +------- + +A variable (or function) cannot be expanded across tokens.

For example, if you want -to make "info" function print " hello", you can write like follows: - - empty := - space := $(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 delimiter: - - $(func-name, arg1, arg2, arg3) - -In this case, "func-name" will receive " arg1", " arg2", " arg3". The presence -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 function, -'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 separators. -For example, $(shell echo hello, world) runs the command "echo hello, world". -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 trick: - - comma := , - $(shell, echo hello$(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 tokens. -The following works: - - RANGE_MIN := 1 - RANGE_MAX := 3 - - config FOO - int "foo" - range $(RANGE_MIN) $(RANGE_MAX) - -But, the following does not work: - - RANGES := 1 3 - - config FOO - int "foo" - range $(RANGES) - -A variable cannot be expanded to any keyword in Kconfig. The following does -not work: - - MY_TYPE := tristate - - config FOO - $(MY_TYPE) "foo" - default y - -Obviously from the design, $(shell command) is expanded in the textual -substitution phase. You cannot pass symbols to the 'shell' function. -The following does not work as expected. - - config ENDIAN_FLAG - string - default "-mbig-endian" if CPU_BIG_ENDIAN - default "-mlittle-endian" if CPU_LITTLE_ENDIAN - - config CC_HAS_ENDIAN_FLAG - def_bool $(shell $(srctree)/scripts/gcc-check-flag ENDIAN_FLAG) - -Instead, you can do like follows so that any function call is statically -expanded. - - config CC_HAS_ENDIAN_FLAG - bool - default $(shell $(srctree)/scripts/gcc-check-flag -mbig-endian) if CPU_BIG_ENDIAN - default $(shell $(srctree)/scripts/gcc-check-flag -mlittle-endian) if CPU_LITTLE_ENDIAN diff --git a/Documentation/kbuild/kconfig.rst b/Documentation/kbuild/kconfig.rst new file mode 100644 index 000000000000..88129af7e539 --- /dev/null +++ b/Documentation/kbuild/kconfig.rst @@ -0,0 +1,300 @@ +=================== +Kconfig make config +=================== + +This file contains some assistance for using `make *config`. + +Use "make help" to list all of the possible configuration targets. + +The xconfig ('qconf'), menuconfig ('mconf'), and nconfig ('nconf') +programs also have embedded help text.

The top Makefile textually includes an arch Makefile +with the name arch/$(ARCH)/Makefile. The arch Makefile supplies +architecture-specific information to the top Makefile. + +Each subdirectory has a kbuild Makefile which carries out the commands +passed down from above. The kbuild Makefile uses information from the +.config file to construct various file lists used by kbuild to build +any built-in or modular targets. + +scripts/Makefile.* contains all the definitions/rules etc. that +are used to build the kernel based on the kbuild makefiles. + + +2 Who does what +=============== + +People have four different relationships with the kernel Makefiles. + +*Users* are people who build kernels. These people type commands such as +"make menuconfig" or "make". They usually do not read or edit +any kernel Makefiles (or any other source files). + +*Normal developers* are people who work on features such as device +drivers, file systems, and network protocols. These people need to +maintain the kbuild Makefiles for the subsystem they are +working on. In order to do this effectively, they need some overall +knowledge about the kernel Makefiles, plus detailed knowledge about the +public interface for kbuild. + +*Arch developers* are people who work on an entire architecture, such +as sparc or ia64. Arch developers need to know about the arch Makefile +as well as kbuild Makefiles. + +*Kbuild developers* are people who work on the kernel build system itself. +These people need to know about all aspects of the kernel Makefiles. + +This document is aimed towards normal developers and arch developers. + + +3 The kbuild files +================== + +Most Makefiles within the kernel are kbuild Makefiles that use the +kbuild infrastructure. This chapter introduces the syntax used in the +kbuild makefiles. +The preferred name for the kbuild files are 'Makefile' but 'Kbuild' can +be used and if both a 'Makefile' and a 'Kbuild' file exists, then the 'Kbuild' +file will be used. + +Section 3.1 "Goal definitions" is a quick intro, further chapters provide +more details, with real examples. + +3.1 Goal definitions +-------------------- + + Goal definitions are the main part (heart) of the kbuild Makefile. + These lines define the files to be built, any special compilation + options, and any subdirectories to be entered recursively. + + The most simple kbuild makefile contains one line: + + Example:: + + obj-y += foo.o + + This tells kbuild that there is one object in that directory, named + foo.o. foo.o will be built from foo.c or foo.S. + + If foo.o shall be built as a module, the variable obj-m is used. + Therefore the following pattern is often used: + + Example:: + + obj-$(CONFIG_FOO) += foo.o + + $(CONFIG_FOO) evaluates to either y (for built-in) or m (for module). + If CONFIG_FOO is neither y nor m, then the file will not be compiled + nor linked. + +3.2 Built-in object goals - obj-y +--------------------------------- + + The kbuild Makefile specifies object files for vmlinux + in the $(obj-y) lists. These lists depend on the kernel + configuration. + + Kbuild compiles all the $(obj-y) files. It then calls + "$(AR) rcSTP" to merge these files into one built-in.a file. + This is a thin archive without a symbol table. It will be later + linked into vmlinux by scripts/link-vmlinux.sh + + The order of files in $(obj-y) is significant. Duplicates in + the lists are allowed: the first instance will be linked into + built-in.a and succeeding instances will be ignored. + + Link order is significant, because certain functions + (module_init() / __initcall) will be called during boot in the + order they appear. So keep in mind that changing the link + order may e.g. change the order in which your SCSI + controllers are detected, and thus your disks are renumbered. + + Example:: + + #drivers/isdn/i4l/Makefile + # Makefile for the kernel ISDN subsystem and device drivers. + # Each configuration option enables a list of files. + obj-$(CONFIG_ISDN_I4L) += isdn.o + obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o + +3.3 Loadable module goals - obj-m +--------------------------------- + + $(obj-m) specifies object files which are built as loadable + kernel modules. + + A module may be built from one source file or several source + files. In the case of one source file, the kbuild makefile + simply adds the file to $(obj-m). + + Example:: + + #drivers/isdn/i4l/Makefile + obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o + + Note: In this example $(CONFIG_ISDN_PPP_BSDCOMP) evaluates to 'm' + + If a kernel module is built from several source files, you specify + that you want to build a module in the same way as above; however, + kbuild needs to know which object files you want to build your + module from, so you have to tell it by setting a $(-y) + variable. + + Example:: + + #drivers/isdn/i4l/Makefile + obj-$(CONFIG_ISDN_I4L) += isdn.o + isdn-y := isdn_net_lib.o isdn_v110.o isdn_common.o + + In this example, the module name will be isdn.o. Kbuild will + compile the objects listed in $(isdn-y) and then run + "$(LD) -r" on the list of these files to generate isdn.o. + + Due to kbuild recognizing $(-y) for composite objects, + you can use the value of a `CONFIG_` symbol to optionally include an + object file as part of a composite object. + + Example:: + + #fs/ext2/Makefile + obj-$(CONFIG_EXT2_FS) += ext2.o + ext2-y := balloc.o dir.o file.o ialloc.o inode.o ioctl.o \ + namei.o super.o symlink.o + ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o xattr_user.o \ + xattr_trusted.o + + In this example, xattr.o, xattr_user.o and xattr_trusted.o are only + part of the composite object ext2.o if $(CONFIG_EXT2_FS_XATTR) + evaluates to 'y'. + + Note: Of course, when you are building objects into the kernel, + the syntax above will also work. So, if you have CONFIG_EXT2_FS=y, + kbuild will build an ext2.o file for you out of the individual + parts and then link this into built-in.a, as you would expect. + +3.4 Objects which export symbols +-------------------------------- + + No special notation is required in the makefiles for + modules exporting symbols. + +3.5 Library file goals - lib-y +------------------------------ + + Objects listed with obj-* are used for modules, or + combined in a built-in.a for that specific directory. + There is also the possibility to list objects that will + be included in a library, lib.a. + All objects listed with lib-y are combined in a single + library for that directory. + Objects that are listed in obj-y and additionally listed in + lib-y will not be included in the library, since they will + be accessible anyway. + For consistency, objects listed in lib-m will be included in lib.a. + + Note that the same kbuild makefile may list files to be built-in + and to be part of a library. Therefore the same directory + may contain both a built-in.a and a lib.a file. + + Example:: + + #arch/x86/lib/Makefile + lib-y := delay.o + + This will create a library lib.a based on delay.o. For kbuild to + actually recognize that there is a lib.a being built, the directory + shall be listed in libs-y. + + See also "6.4 List directories to visit when descending". + + Use of lib-y is normally restricted to `lib/` and `arch/*/lib`. + +3.6 Descending down in directories +---------------------------------- + + A Makefile is only responsible for building objects in its own + directory. Files in subdirectories should be taken care of by + Makefiles in these subdirs. The build system will automatically + invoke make recursively in subdirectories, provided you let it know of + them. + + To do so, obj-y and obj-m are used. + ext2 lives in a separate directory, and the Makefile present in fs/ + tells kbuild to descend down using the following assignment. + + Example:: + + #fs/Makefile + obj-$(CONFIG_EXT2_FS) += ext2/ + + If CONFIG_EXT2_FS is set to either 'y' (built-in) or 'm' (modular) + the corresponding obj- variable will be set, and kbuild will descend + down in the ext2 directory. + Kbuild only uses this information to decide that it needs to visit + the directory, it is the Makefile in the subdirectory that + specifies what is modular and what is built-in. + + It is good practice to use a `CONFIG_` variable when assigning directory + names. This allows kbuild to totally skip the directory if the + corresponding `CONFIG_` option is neither 'y' nor 'm'. + +3.7 Compilation flags +--------------------- + + ccflags-y, asflags-y and ldflags-y + These three flags apply only to the kbuild makefile in which they + are assigned. They are used for all the normal cc, as and ld + invocations happening during a recursive build. + Note: Flags with the same behaviour were previously named: + EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS. + They are still supported but their usage is deprecated. + + ccflags-y specifies options for compiling with $(CC). + + Example:: + + # drivers/acpi/acpica/Makefile + ccflags-y := -Os -D_LINUX -DBUILDING_ACPICA + ccflags-$(CONFIG_ACPI_DEBUG) += -DACPI_DEBUG_OUTPUT + + This variable is necessary because the top Makefile owns the + variable $(KBUILD_CFLAGS) and uses it for compilation flags for the + entire tree. + + asflags-y specifies options for assembling with $(AS). + + Example:: + + #arch/sparc/kernel/Makefile + asflags-y := -ansi + + ldflags-y specifies options for linking with $(LD). + + Example:: + + #arch/cris/boot/compressed/Makefile + ldflags-y += -T $(srctree)/$(src)/decompress_$(arch-y).lds + + subdir-ccflags-y, subdir-asflags-y + The two flags listed above are similar to ccflags-y and asflags-y. + The difference is that the subdir- variants have effect for the kbuild + file where they are present and all subdirectories. + Options specified using subdir-* are added to the commandline before + the options specified using the non-subdir variants. + + Example:: + + subdir-ccflags-y := -Werror + + CFLAGS_$@, AFLAGS_$@ + CFLAGS_$@ and AFLAGS_$@ only apply to commands in current + kbuild makefile. + + $(CFLAGS_$@) specifies per-file options for $(CC). The $@ + part has a literal value which specifies the file that it is for. + + Example:: + + # drivers/scsi/Makefile + CFLAGS_aha152x.o = -DAHA152X_STAT -DAUTOCONF + CFLAGS_gdth.o = # -DDEBUG_GDTH=2 -D__SERIAL__ -D__COM2__ \ + -DGDTH_STATISTICS + + These two lines specify compilation flags for aha152x.o and gdth.o. + + $(AFLAGS_$@) is a similar feature for source files in assembly + languages. + + Example:: + + # arch/arm/kernel/Makefile + AFLAGS_head.o := -DTEXT_OFFSET=$(TEXT_OFFSET) + AFLAGS_crunch-bits.o := -Wa,-mcpu=ep9312 + AFLAGS_iwmmxt.o := -Wa,-mcpu=iwmmxt + + +3.9 Dependency tracking +----------------------- + + Kbuild tracks dependencies on the following: + 1) All prerequisite files (both `*.c` and `*.h`) + 2) `CONFIG_` options used in all prerequisite files + 3) Command-line used to compile target + + Thus, if you change an option to $(CC) all affected files will + be re-compiled. + +3.10 Special Rules +------------------ + + Special rules are used when the kbuild infrastructure does + not provide the required support. A typical example is + header files generated during the build process. + Another example are the architecture-specific Makefiles which + need special rules to prepare boot images etc. + + Special rules are written as normal Make rules. + Kbuild is not executing in the directory where the Makefile is + located, so all special rules shall provide a relative + path to prerequisite files and target files. + + Two variables are used when defining special rules: + + $(src) + $(src) is a relative path which points to the directory + where the Makefile is located. Always use $(src) when + referring to files located in the src tree. + + $(obj) + $(obj) is a relative path which points to the directory + where the target is saved. Always use $(obj) when + referring to generated files. + + Example:: + + #drivers/scsi/Makefile + $(obj)/53c8xx_d.h: $(src)/53c7,8xx.scr $(src)/script_asm.pl + $(CPP) -DCHIP=810 - < $< | ... $(src)/script_asm.pl + + This is a special rule, following the normal syntax + required by make. + + The target file depends on two prerequisite files. References + to the target file are prefixed with $(obj), references + to prerequisites are referenced with $(src) (because they are not + generated files). + + $(kecho) + echoing information to user in a rule is often a good practice + but when execution "make -s" one does not expect to see any output + except for warnings/errors. + To support this kbuild defines $(kecho) which will echo out the + text following $(kecho) to stdout except if "make -s" is used. + + Example:: + + #arch/blackfin/boot/Makefile + $(obj)/vmImage: $(obj)/vmlinux.gz + $(call if_changed,uimage) + @$(kecho) 'Kernel: $@ is ready' + + +3.11 $(CC) support functions +---------------------------- + + The kernel may be built with several different versions of + $(CC), each supporting a unique set of features and options. + kbuild provides basic support to check for valid options for $(CC). + $(CC) is usually the gcc compiler, but other alternatives are + available. + + as-option + as-option is used to check if $(CC) -- when used to compile + assembler (`*.S`) files -- supports the given option. An optional + second option may be specified if the first option is not supported. + + Example:: + + #arch/sh/Makefile + cflags-y += $(call as-option,-Wa$(comma)-isa=$(isa-y),) + + In the above example, cflags-y will be assigned the option + -Wa$(comma)-isa=$(isa-y) if it is supported by $(CC). + The second argument is optional, and if supplied will be used + if first argument is not supported. + + cc-ldoption + cc-ldoption is used to check if $(CC) when used to link object files + supports the given option. An optional second option may be + specified if first option are not supported. + + Example:: + + #arch/x86/kernel/Makefile + vsyscall-flags += $(call cc-ldoption, -Wl$(comma)--hash-style=sysv) + + In the above example, vsyscall-flags will be assigned the option + -Wl$(comma)--hash-style=sysv if it is supported by $(CC). + The second argument is optional, and if supplied will be used + if first argument is not supported. + + as-instr + as-instr checks if the assembler reports a specific instruction + and then outputs either option1 or option2 + C escapes are supported in the test instruction + Note: as-instr-option uses KBUILD_AFLAGS for $(AS) options + + cc-option + cc-option is used to check if $(CC) supports a given option, and if + not supported to use an optional second option. + + Example:: + + #arch/x86/Makefile + cflags-y += $(call cc-option,-march=pentium-mmx,-march=i586) + + In the above example, cflags-y will be assigned the option + -march=pentium-mmx if supported by $(CC), otherwise -march=i586. + The second argument to cc-option is optional, and if omitted, + cflags-y will be assigned no value if first option is not supported. + Note: cc-option uses KBUILD_CFLAGS for $(CC) options + + cc-option-yn + cc-option-yn is used to check if gcc supports a given option + and return 'y' if supported, otherwise 'n'. + + Example:: + + #arch/ppc/Makefile + biarch := $(call cc-option-yn, -m32) + aflags-$(biarch) += -a32 + cflags-$(biarch) += -m32 + + In the above example, $(biarch) is set to y if $(CC) supports the -m32 + option. When $(biarch) equals 'y', the expanded variables $(aflags-y) + and $(cflags-y) will be assigned the values -a32 and -m32, + respectively. + Note: cc-option-yn uses KBUILD_CFLAGS for $(CC) options + + cc-disable-warning + cc-disable-warning checks if gcc supports a given warning and returns + the commandline switch to disable it. This special function is needed, + because gcc 4.4 and later accept any unknown -Wno-* option and only + warn about it if there is another warning in the source file. + + Example:: + + KBUILD_CFLAGS += $(call cc-disable-warning, unused-but-set-variable) + + In the above example, -Wno-unused-but-set-variable will be added to + KBUILD_CFLAGS only if gcc really accepts it. + + cc-ifversion + cc-ifversion tests the version of $(CC) and equals the fourth parameter + if version expression is true, or the fifth (if given) if the version + expression is false. + + Example:: + + #fs/reiserfs/Makefile + ccflags-y := $(call cc-ifversion, -lt, 0402, -O1) + + In this example, ccflags-y will be assigned the value -O1 if the + $(CC) version is less than 4.2. + cc-ifversion takes all the shell operators: + -eq, -ne, -lt, -le, -gt, and -ge + The third parameter may be a text as in this example, but it may also + be an expanded variable or a macro. + + cc-cross-prefix + cc-cross-prefix is used to check if there exists a $(CC) in path with + one of the listed prefixes. The first prefix where there exist a + prefix$(CC) in the PATH is returned - and if no prefix$(CC) is found + then nothing is returned. + Additional prefixes are separated by a single space in the + call of cc-cross-prefix. + This functionality is useful for architecture Makefiles that try + to set CROSS_COMPILE to well-known values but may have several + values to select between. + It is recommended only to try to set CROSS_COMPILE if it is a cross + build (host arch is different from target arch). And if CROSS_COMPILE + is already set then leave it with the old value. + + Example:: + + #arch/m68k/Makefile + ifneq ($(SUBARCH),$(ARCH)) + ifeq ($(CROSS_COMPILE),) + CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu-) + endif + endif + +3.12 $(LD) support functions +---------------------------- + + ld-option + ld-option is used to check if $(LD) supports the supplied option. + ld-option takes two options as arguments. + The second argument is an optional option that can be used if the + first option is not supported by $(LD). + + Example:: + + #Makefile + LDFLAGS_vmlinux += $(call ld-option, -X) + + +4 Host Program support +====================== + +Kbuild supports building executables on the host for use during the +compilation stage. +Two steps are required in order to use a host executable. + +The first step is to tell kbuild that a host program exists. This is +done utilising the variable hostprogs-y. + +The second step is to add an explicit dependency to the executable. +This can be done in two ways. Either add the dependency in a rule, +or utilise the variable $(always). +Both possibilities are described in the following. + +4.1 Simple Host Program +----------------------- + + In some cases there is a need to compile and run a program on the + computer where the build is running. + The following line tells kbuild that the program bin2hex shall be + built on the build host. + + Example:: + + hostprogs-y := bin2hex + + Kbuild assumes in the above example that bin2hex is made from a single + c-source file named bin2hex.c located in the same directory as + the Makefile. + +4.2 Composite Host Programs +--------------------------- + + Host programs can be made up based on composite objects. + The syntax used to define composite objects for host programs is + similar to the syntax used for kernel objects. + $(-objs) lists all objects used to link the final + executable. + + Example:: + + #scripts/lxdialog/Makefile + hostprogs-y := lxdialog + lxdialog-objs := checklist.o lxdialog.o + + Objects with extension .o are compiled from the corresponding .c + files. In the above example, checklist.c is compiled to checklist.o + and lxdialog.c is compiled to lxdialog.o. + + Finally, the two .o files are linked to the executable, lxdialog. + Note: The syntax -y is not permitted for host-programs. + +4.3 Using C++ for host programs +------------------------------- + + kbuild offers support for host programs written in C++. This was + introduced solely to support kconfig, and is not recommended + for general use. + + Example:: + + #scripts/kconfig/Makefile + hostprogs-y := qconf + qconf-cxxobjs := qconf.o + + In the example above the executable is composed of the C++ file + qconf.cc - identified by $(qconf-cxxobjs). + + If qconf is composed of a mixture of .c and .cc files, then an + additional line can be used to identify this. + + Example:: + + #scripts/kconfig/Makefile + hostprogs-y := qconf + qconf-cxxobjs := qconf.o + qconf-objs := check.o + +4.4 Controlling compiler options for host programs +-------------------------------------------------- + + When compiling host programs, it is possible to set specific flags. + The programs will always be compiled utilising $(HOSTCC) passed + the options specified in $(KBUILD_HOSTCFLAGS). + To set flags that will take effect for all host programs created + in that Makefile, use the variable HOST_EXTRACFLAGS. + + Example:: + + #scripts/lxdialog/Makefile + HOST_EXTRACFLAGS += -I/usr/include/ncurses + + To set specific flags for a single file the following construction + is used: + + Example:: + + #arch/ppc64/boot/Makefile + HOSTCFLAGS_piggyback.o := -DKERNELBASE=$(KERNELBASE) + + It is also possible to specify additional options to the linker. + + Example:: + + #scripts/kconfig/Makefile + HOSTLDLIBS_qconf := -L$(QTDIR)/lib + + When linking qconf, it will be passed the extra option + "-L$(QTDIR)/lib". + +4.5 When host programs are actually built +----------------------------------------- + + Kbuild will only build host-programs when they are referenced + as a prerequisite. + This is possible in two ways: + + (1) List the prerequisite explicitly in a special rule. + + Example:: + + #drivers/pci/Makefile + hostprogs-y := gen-devlist + $(obj)/devlist.h: $(src)/pci.ids $(obj)/gen-devlist + ( cd $(obj); ./gen-devlist ) < $< + + The target $(obj)/devlist.h will not be built before + $(obj)/gen-devlist is updated. Note that references to + the host programs in special rules must be prefixed with $(obj). + + (2) Use $(always) + + When there is no suitable special rule, and the host program + shall be built when a makefile is entered, the $(always) + variable shall be used. + + Example:: + + #scripts/lxdialog/Makefile + hostprogs-y := lxdialog + always := $(hostprogs-y) + + This will tell kbuild to build lxdialog even if not referenced in + any rule. + +4.6 Using hostprogs-$(CONFIG_FOO) +--------------------------------- + + A typical pattern in a Kbuild file looks like this: + + Example:: + + #scripts/Makefile + hostprogs-$(CONFIG_KALLSYMS) += kallsyms + + Kbuild knows about both 'y' for built-in and 'm' for module. + So if a config symbol evaluates to 'm', kbuild will still build + the binary. In other words, Kbuild handles hostprogs-m exactly + like hostprogs-y. But only hostprogs-y is recommended to be used + when no CONFIG symbols are involved. + +5 Kbuild clean infrastructure +============================= + +"make clean" deletes most generated files in the obj tree where the kernel +is compiled. This includes generated files such as host programs. +Kbuild knows targets listed in $(hostprogs-y), $(hostprogs-m), $(always), +$(extra-y) and $(targets). They are all deleted during "make clean". +Files matching the patterns "*.[oas]", "*.ko", plus some additional files +generated by kbuild are deleted all over the kernel src tree when +"make clean" is executed. + +Additional files can be specified in kbuild makefiles by use of $(clean-files). + + Example:: + + #lib/Makefile + clean-files := crc32table.h + +When executing "make clean", the file "crc32table.h" will be deleted. +Kbuild will assume files to be in the same relative directory as the +Makefile, except if prefixed with $(objtree). + +To delete a directory hierarchy use: + + Example:: + + #scripts/package/Makefile + clean-dirs := $(objtree)/debian/ + +This will delete the directory debian in the toplevel directory, including all +subdirectories. + +To exclude certain files from make clean, use the $(no-clean-files) variable. +This is only a special case used in the top level Kbuild file: + + Example:: + + #Kbuild + no-clean-files := $(bounds-file) $(offsets-file) + +Usually kbuild descends down in subdirectories due to "obj-* := dir/", +but in the architecture makefiles where the kbuild infrastructure +is not sufficient this sometimes needs to be explicit. + + Example:: + + #arch/x86/boot/Makefile + subdir- := compressed/ + +The above assignment instructs kbuild to descend down in the +directory compressed/ when "make clean" is executed. + +To support the clean infrastructure in the Makefiles that build the +final bootimage there is an optional target named archclean: + + Example:: + + #arch/x86/Makefile + archclean: + $(Q)$(MAKE) $(clean)=arch/x86/boot + +When "make clean" is executed, make will descend down in arch/x86/boot, +and clean as usual. The Makefile located in arch/x86/boot/ may use +the subdir- trick to descend further down. + +Note 1: arch/$(ARCH)/Makefile cannot use "subdir-", because that file is +included in the top level makefile, and the kbuild infrastructure +is not operational at that point. + +Note 2: All directories listed in core-y, libs-y, drivers-y and net-y will +be visited during "make clean". + +6 Architecture Makefiles +======================== + +The top level Makefile sets up the environment and does the preparation, +before starting to descend down in the individual directories. +The top level makefile contains the generic part, whereas +arch/$(ARCH)/Makefile contains what is required to set up kbuild +for said architecture. +To do so, arch/$(ARCH)/Makefile sets up a number of variables and defines +a few targets. + +When kbuild executes, the following steps are followed (roughly): + +1) Configuration of the kernel => produce .config +2) Store kernel version in include/linux/version.h +3) Updating all other prerequisites to the target prepare: + - Additional prerequisites are specified in arch/$(ARCH)/Makefile +4) Recursively descend down in all directories listed in + init-* core* drivers-* net-* libs-* and build all targets. + - The values of the above variables are expanded in arch/$(ARCH)/Makefile. +5) All object files are then linked and the resulting file vmlinux is + located at the root of the obj tree. + The very first objects linked are listed in head-y, assigned by + arch/$(ARCH)/Makefile. +6) Finally, the architecture-specific part does any required post processing + and builds the final bootimage. + - This includes building boot records + - Preparing initrd images and the like + + +6.1 Set variables to tweak the build to the architecture +-------------------------------------------------------- + + LDFLAGS + Generic $(LD) options + + Flags used for all invocations of the linker. + Often specifying the emulation is sufficient. + + Example:: + + #arch/s390/Makefile + LDFLAGS := -m elf_s390 + + Note: ldflags-y can be used to further customise + the flags used. See chapter 3.7. + + LDFLAGS_vmlinux + Options for $(LD) when linking vmlinux + + LDFLAGS_vmlinux is used to specify additional flags to pass to + the linker when linking the final vmlinux image. + LDFLAGS_vmlinux uses the LDFLAGS_$@ support. + + Example:: + + #arch/x86/Makefile + LDFLAGS_vmlinux := -e stext + + OBJCOPYFLAGS + objcopy flags + + When $(call if_changed,objcopy) is used to translate a .o file, + the flags specified in OBJCOPYFLAGS will be used. + $(call if_changed,objcopy) is often used to generate raw binaries on + vmlinux. + + Example:: + + #arch/s390/Makefile + OBJCOPYFLAGS := -O binary + + #arch/s390/boot/Makefile + $(obj)/image: vmlinux FORCE + $(call if_changed,objcopy) + + In this example, the binary $(obj)/image is a binary version of + vmlinux. The usage of $(call if_changed,xxx) will be described later. + + KBUILD_AFLAGS + $(AS) assembler flags + + Default value - see top level Makefile + Append or modify as required per architecture. + + Example:: + + #arch/sparc64/Makefile + KBUILD_AFLAGS += -m64 -mcpu=ultrasparc + + KBUILD_CFLAGS + $(CC) compiler flags + + Default value - see top level Makefile + Append or modify as required per architecture. + + Often, the KBUILD_CFLAGS variable depends on the configuration. + + Example:: + + #arch/x86/boot/compressed/Makefile + cflags-$(CONFIG_X86_32) := -march=i386 + cflags-$(CONFIG_X86_64) := -mcmodel=small + KBUILD_CFLAGS += $(cflags-y) + + Many arch Makefiles dynamically run the target C compiler to + probe supported options:: + + #arch/x86/Makefile + + ... + cflags-$(CONFIG_MPENTIUMII) += $(call cc-option,\ + -march=pentium2,-march=i686) + ... + # Disable unit-at-a-time mode ... + KBUILD_CFLAGS += $(call cc-option,-fno-unit-at-a-time) + ... + + + The first example utilises the trick that a config option expands + to 'y' when selected. + + KBUILD_AFLAGS_KERNEL + $(AS) options specific for built-in + + $(KBUILD_AFLAGS_KERNEL) contains extra C compiler flags used to compile + resident kernel code. + + KBUILD_AFLAGS_MODULE + Options for $(AS) when building modules + + $(KBUILD_AFLAGS_MODULE) is used to add arch-specific options that + are used for $(AS). + + From commandline AFLAGS_MODULE shall be used (see kbuild.txt). + + KBUILD_CFLAGS_KERNEL + $(CC) options specific for built-in + + $(KBUILD_CFLAGS_KERNEL) contains extra C compiler flags used to compile + resident kernel code. + + KBUILD_CFLAGS_MODULE + Options for $(CC) when building modules + + $(KBUILD_CFLAGS_MODULE) is used to add arch-specific options that + are used for $(CC). + From commandline CFLAGS_MODULE shall be used (see kbuild.txt). + + KBUILD_LDFLAGS_MODULE + Options for $(LD) when linking modules + + $(KBUILD_LDFLAGS_MODULE) is used to add arch-specific options + used when linking modules. This is often a linker script. + + From commandline LDFLAGS_MODULE shall be used (see kbuild.txt). + + KBUILD_ARFLAGS Options for $(AR) when creating archives + + $(KBUILD_ARFLAGS) set by the top level Makefile to "D" (deterministic + mode) if this option is supported by $(AR). + + ARCH_CPPFLAGS, ARCH_AFLAGS, ARCH_CFLAGS Overrides the kbuild defaults + + These variables are appended to the KBUILD_CPPFLAGS, + KBUILD_AFLAGS, and KBUILD_CFLAGS, respectively, after the + top-level Makefile has set any other flags. This provides a + means for an architecture to override the defaults. + + +6.2 Add prerequisites to archheaders +------------------------------------ + + The archheaders: rule is used to generate header files that + may be installed into user space by "make header_install" or + "make headers_install_all". In order to support + "make headers_install_all", this target has to be able to run + on an unconfigured tree, or a tree configured for another + architecture. + + It is run before "make archprepare" when run on the + architecture itself. + + +6.3 Add prerequisites to archprepare +------------------------------------ + + The archprepare: rule is used to list prerequisites that need to be + built before starting to descend down in the subdirectories. + This is usually used for header files containing assembler constants. + + Example:: + + #arch/arm/Makefile + archprepare: maketools + + In this example, the file target maketools will be processed + before descending down in the subdirectories. + See also chapter XXX-TODO that describe how kbuild supports + generating offset header files. + + +6.4 List directories to visit when descending +--------------------------------------------- + + An arch Makefile cooperates with the top Makefile to define variables + which specify how to build the vmlinux file. Note that there is no + corresponding arch-specific section for modules; the module-building + machinery is all architecture-independent. + + + head-y, init-y, core-y, libs-y, drivers-y, net-y + $(head-y) lists objects to be linked first in vmlinux. + + $(libs-y) lists directories where a lib.a archive can be located. + + The rest list directories where a built-in.a object file can be + located. + + $(init-y) objects will be located after $(head-y). + + Then the rest follows in this order: + + $(core-y), $(libs-y), $(drivers-y) and $(net-y). + + The top level Makefile defines values for all generic directories, + and arch/$(ARCH)/Makefile only adds architecture-specific + directories. + + Example:: + + #arch/sparc64/Makefile + core-y += arch/sparc64/kernel/ + libs-y += arch/sparc64/prom/ arch/sparc64/lib/ + drivers-$(CONFIG_OPROFILE) += arch/sparc64/oprofile/ + + +6.5 Architecture-specific boot images +------------------------------------- + + An arch Makefile specifies goals that take the vmlinux file, compress + it, wrap it in bootstrapping code, and copy the resulting files + somewhere. This includes various kinds of installation commands. + The actual goals are not standardized across architectures. + + It is common to locate any additional processing in a boot/ + directory below arch/$(ARCH)/. + + Kbuild does not provide any smart way to support building a + target specified in boot/. Therefore arch/$(ARCH)/Makefile shall + call make manually to build a target in boot/. + + The recommended approach is to include shortcuts in + arch/$(ARCH)/Makefile, and use the full path when calling down + into the arch/$(ARCH)/boot/Makefile. + + Example:: + + #arch/x86/Makefile + boot := arch/x86/boot + bzImage: vmlinux + $(Q)$(MAKE) $(build)=$(boot) $(boot)/$@ + + "$(Q)$(MAKE) $(build)=" is the recommended way to invoke + make in a subdirectory. + + There are no rules for naming architecture-specific targets, + but executing "make help" will list all relevant targets. + To support this, $(archhelp) must be defined. + + Example:: + + #arch/x86/Makefile + define archhelp + echo '* bzImage - Image (arch/$(ARCH)/boot/bzImage)' + endif + + When make is executed without arguments, the first goal encountered + will be built. In the top level Makefile the first goal present + is all:. + An architecture shall always, per default, build a bootable image. + In "make help", the default goal is highlighted with a '*'. + Add a new prerequisite to all: to select a default goal different + from vmlinux. + + Example:: + + #arch/x86/Makefile + all: bzImage + + When "make" is executed without arguments, bzImage will be built. + +6.6 Building non-kbuild targets +------------------------------- + + extra-y + extra-y specifies additional targets created in the current + directory, in addition to any targets specified by `obj-*`. + + Listing all targets in extra-y is required for two purposes: + + 1) Enable kbuild to check changes in command lines + + - When $(call if_changed,xxx) is used + + 2) kbuild knows what files to delete during "make clean" + + Example:: + + #arch/x86/kernel/Makefile + extra-y := head.o init_task.o + + In this example, extra-y is used to list object files that + shall be built, but shall not be linked as part of built-in.a. + + +6.7 Commands useful for building a boot image +--------------------------------------------- + + Kbuild provides a few macros that are useful when building a + boot image. + + if_changed + if_changed is the infrastructure used for the following commands. + + Usage:: + + target: source(s) FORCE + $(call if_changed,ld/objcopy/gzip/...) + + When the rule is evaluated, it is checked to see if any files + need an update, or the command line has changed since the last + invocation. The latter will force a rebuild if any options + to the executable have changed. + Any target that utilises if_changed must be listed in $(targets), + otherwise the command line check will fail, and the target will + always be built. + Assignments to $(targets) are without $(obj)/ prefix. + if_changed may be used in conjunction with custom commands as + defined in 6.8 "Custom kbuild commands". + + Note: It is a typical mistake to forget the FORCE prerequisite. + Another common pitfall is that whitespace is sometimes + significant; for instance, the below will fail (note the extra space + after the comma):: + + target: source(s) FORCE + + **WRONG!** $(call if_changed, ld/objcopy/gzip/...) + + Note: + if_changed should not be used more than once per target. + It stores the executed command in a corresponding .cmd + + file and multiple calls would result in overwrites and + unwanted results when the target is up to date and only the + tests on changed commands trigger execution of commands. + + ld + Link target. Often, LDFLAGS_$@ is used to set specific options to ld. + + Example:: + + #arch/x86/boot/Makefile + LDFLAGS_bootsect := -Ttext 0x0 -s --oformat binary + LDFLAGS_setup := -Ttext 0x0 -s --oformat binary -e begtext + + targets += setup setup.o bootsect bootsect.o + $(obj)/setup $(obj)/bootsect: %: %.o FORCE + $(call if_changed,ld) + + In this example, there are two possible targets, requiring different + options to the linker. The linker options are specified using the + LDFLAGS_$@ syntax - one for each potential target. + $(targets) are assigned all potential targets, by which kbuild knows + the targets and will: + + 1) check for commandline changes + 2) delete target during make clean + + The ": %: %.o" part of the prerequisite is a shorthand that + frees us from listing the setup.o and bootsect.o files. + + Note: + It is a common mistake to forget the "targets :=" assignment, + resulting in the target file being recompiled for no + obvious reason. + + objcopy + Copy binary. Uses OBJCOPYFLAGS usually specified in + arch/$(ARCH)/Makefile. + OBJCOPYFLAGS_$@ may be used to set additional options. + + gzip + Compress target. Use maximum compression to compress target. + + Example:: + + #arch/x86/boot/compressed/Makefile + $(obj)/vmlinux.bin.gz: $(vmlinux.bin.all-y) FORCE + $(call if_changed,gzip) + + dtc + Create flattened device tree blob object suitable for linking + into vmlinux. Device tree blobs linked into vmlinux are placed + in an init section in the image. Platform code *must* copy the + blob to non-init memory prior to calling unflatten_device_tree(). + + To use this command, simply add `*.dtb` into obj-y or targets, or make + some other target depend on `%.dtb` + + A central rule exists to create `$(obj)/%.dtb` from `$(src)/%.dts`; + architecture Makefiles do no need to explicitly write out that rule. + + Example:: + + targets += $(dtb-y) + DTC_FLAGS ?= -p 1024 + +6.8 Custom kbuild commands +-------------------------- + + When kbuild is executing with KBUILD_VERBOSE=0, then only a shorthand + of a command is normally displayed. + To enable this behaviour for custom commands kbuild requires + two variables to be set:: + + quiet_cmd_ - what shall be echoed + cmd_ - the command to execute + + Example:: + + # + quiet_cmd_image = BUILD $@ + cmd_image = $(obj)/tools/build $(BUILDFLAGS) \ + $(obj)/vmlinux.bin > $@ + + targets += bzImage + $(obj)/bzImage: $(obj)/vmlinux.bin $(obj)/tools/build FORCE + $(call if_changed,image) + @echo 'Kernel: $@ is ready' + + When updating the $(obj)/bzImage target, the line: + + BUILD arch/x86/boot/bzImage + + will be displayed with "make KBUILD_VERBOSE=0". + + +--- 6.9 Preprocessing linker scripts + + When the vmlinux image is built, the linker script + arch/$(ARCH)/kernel/vmlinux.lds is used. + The script is a preprocessed variant of the file vmlinux.lds.S + located in the same directory. + kbuild knows .lds files and includes a rule `*lds.S` -> `*lds`. + + Example:: + + #arch/x86/kernel/Makefile + always := vmlinux.lds + + #Makefile + export CPPFLAGS_vmlinux.lds += -P -C -U$(ARCH) + + The assignment to $(always) is used to tell kbuild to build the + target vmlinux.lds. + The assignment to $(CPPFLAGS_vmlinux.lds) tells kbuild to use the + specified options when building the target vmlinux.lds. + + When building the `*.lds` target, kbuild uses the variables:: + + KBUILD_CPPFLAGS : Set in top-level Makefile + cppflags-y : May be set in the kbuild makefile + CPPFLAGS_$(@F) : Target-specific flags. + Note that the full filename is used in this + assignment. + + The kbuild infrastructure for `*lds` files is used in several + architecture-specific files. + +6.10 Generic header files +------------------------- + + The directory include/asm-generic contains the header files + that may be shared between individual architectures. + The recommended approach how to use a generic header file is + to list the file in the Kbuild file. + See "7.2 generic-y" for further info on syntax etc. + +6.11 Post-link pass +------------------- + + If the file arch/xxx/Makefile.postlink exists, this makefile + will be invoked for post-link objects (vmlinux and modules.ko) + for architectures to run post-link passes on. Must also handle + the clean target. + + This pass runs after kallsyms generation. If the architecture + needs to modify symbol locations, rather than manipulate the + kallsyms, it may be easier to add another postlink target for + .tmp_vmlinux? targets to be called from link-vmlinux.sh. + + For example, powerpc uses this to check relocation sanity of + the linked vmlinux file. + +7 Kbuild syntax for exported headers +------------------------------------ + +The kernel includes a set of headers that is exported to userspace. +Many headers can be exported as-is but other headers require a +minimal pre-processing before they are ready for user-space. +The pre-processing does: + +- drop kernel-specific annotations +- drop include of compiler.h +- drop all sections that are kernel internal (guarded by `ifdef __KERNEL__`) + +All headers under include/uapi/, include/generated/uapi/, +arch//include/uapi/ and arch//include/generated/uapi/ +are exported. + +A Kbuild file may be defined under arch//include/uapi/asm/ and +arch//include/asm/ to list asm files coming from asm-generic. +See subsequent chapter for the syntax of the Kbuild file. + +7.1 no-export-headers +--------------------- + + no-export-headers is essentially used by include/uapi/linux/Kbuild to + avoid exporting specific headers (e.g. kvm.h) on architectures that do + not support it. It should be avoided as much as possible. + +7.2 generic-y +------------- + + If an architecture uses a verbatim copy of a header from + include/asm-generic then this is listed in the file + arch/$(ARCH)/include/asm/Kbuild like this: + + Example:: + + #arch/x86/include/asm/Kbuild + generic-y += termios.h + generic-y += rtc.h + + During the prepare phase of the build a wrapper include + file is generated in the directory:: + + arch/$(ARCH)/include/generated/asm + + When a header is exported where the architecture uses + the generic header a similar wrapper is generated as part + of the set of exported headers in the directory:: + + usr/include/asm + + The generated wrapper will in both cases look like the following: + + Example: termios.h:: + + #include + +7.3 generated-y +--------------- + + If an architecture generates other header files alongside generic-y + wrappers, generated-y specifies them. + + This prevents them being treated as stale asm-generic wrappers and + removed. + + Example:: + + #arch/x86/include/asm/Kbuild + generated-y += syscalls_32.h + +7.4 mandatory-y +--------------- + + mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild + to define the minimum set of ASM headers that all architectures must have. + + This works like optional generic-y. If a mandatory header is missing + in arch/$(ARCH)/include/(uapi/)/asm, Kbuild will automatically generate + a wrapper of the asm-generic one. + + The convention is to list one subdir per line and + preferably in alphabetic order. + +8 Kbuild Variables +================== + +The top Makefile exports the following variables: + + VERSION, PATCHLEVEL, SUBLEVEL, EXTRAVERSION + These variables define the current kernel version. A few arch + Makefiles actually use these values directly; they should use + $(KERNELRELEASE) instead. + + $(VERSION), $(PATCHLEVEL), and $(SUBLEVEL) define the basic + three-part version number, such as "2", "4", and "0". These three + values are always numeric. + + $(EXTRAVERSION) defines an even tinier sublevel for pre-patches + or additional patches. It is usually some non-numeric string + such as "-pre4", and is often blank. + + KERNELRELEASE + $(KERNELRELEASE) is a single string such as "2.4.0-pre4", suitable + for constructing installation directory names or showing in + version strings. Some arch Makefiles use it for this purpose. + + ARCH + This variable defines the target architecture, such as "i386", + "arm", or "sparc". Some kbuild Makefiles test $(ARCH) to + determine which files to compile. + + By default, the top Makefile sets $(ARCH) to be the same as the + host system architecture. For a cross build, a user may + override the value of $(ARCH) on the command line:: + + make ARCH=m68k ... + + + INSTALL_PATH + This variable defines a place for the arch Makefiles to install + the resident kernel image and System.map file. + Use this for architecture-specific install targets. + + INSTALL_MOD_PATH, MODLIB + $(INSTALL_MOD_PATH) specifies a prefix to $(MODLIB) for module + installation. This variable is not defined in the Makefile but + may be passed in by the user if desired. + + $(MODLIB) specifies the directory for module installation. + The top Makefile defines $(MODLIB) to + $(INSTALL_MOD_PATH)/lib/modules/$(KERNELRELEASE). The user may + override this value on the command line if desired. + + INSTALL_MOD_STRIP + If this variable is specified, it will cause modules to be stripped + after they are installed. If INSTALL_MOD_STRIP is '1', then the + default option --strip-debug will be used. Otherwise, the + INSTALL_MOD_STRIP value will be used as the option(s) to the strip + command. + + +9 Makefile language +=================== + +The kernel Makefiles are designed to be run with GNU Make. The Makefiles +use only the documented features of GNU Make, but they do use many +GNU extensions. + +GNU Make supports elementary list-processing functions. The kernel +Makefiles use a novel style of list building and manipulation with few +"if" statements. + +GNU Make has two assignment operators, ":=" and "=". ":=" performs +immediate evaluation of the right-hand side and stores an actual string +into the left-hand side. "=" is like a formula definition; it stores the +right-hand side in an unevaluated form and then evaluates this form each +time the left-hand side is used. + +There are some cases where "=" is appropriate. Usually, though, ":=" +is the right choice. + +10 Credits +========== + +- Original version made by Michael Elizabeth Chastain, +- Updates by Kai Germaschewski +- Updates by Sam Ravnborg +- Language QA by Jan Engelhardt + +11 TODO +======= + +- Describe how kbuild supports shipped files with _shipped. +- Generating offset header files. +- Add more variables to section 7? diff --git a/Documentation/kbuild/makefiles.txt b/Documentation/kbuild/makefiles.txt deleted file mode 100644 index d65ad5746f94..000000000000 --- a/Documentation/kbuild/makefiles.txt +++ /dev/null @@ -1,1369 +0,0 @@ -Linux Kernel Makefiles - -This document describes the Linux kernel Makefiles. - -=== Table of Contents - - === 1 Overview - === 2 Who does what - === 3 The kbuild files - --- 3.1 Goal definitions - --- 3.2 Built-in object goals - obj-y - --- 3.3 Loadable module goals - obj-m - --- 3.4 Objects which export symbols - --- 3.5 Library file goals - lib-y - --- 3.6 Descending down in directories - --- 3.7 Compilation flags - --- 3.8 Command line dependency - --- 3.9 Dependency tracking - --- 3.10 Special Rules - --- 3.11 $(CC) support functions - --- 3.12 $(LD) support functions - - === 4 Host Program support - --- 4.1 Simple Host Program - --- 4.2 Composite Host Programs - --- 4.3 Using C++ for host programs - --- 4.4 Controlling compiler options for host programs - --- 4.5 When host programs are actually built - --- 4.6 Using hostprogs-$(CONFIG_FOO) - - === 5 Kbuild clean infrastructure - - === 6 Architecture Makefiles - --- 6.1 Set variables to tweak the build to the architecture - --- 6.2 Add prerequisites to archheaders: - --- 6.3 Add prerequisites to archprepare: - --- 6.4 List directories to visit when descending - --- 6.5 Architecture-specific boot images - --- 6.6 Building non-kbuild targets - --- 6.7 Commands useful for building a boot image - --- 6.8 Custom kbuild commands - --- 6.9 Preprocessing linker scripts - --- 6.10 Generic header files - --- 6.11 Post-link pass - - === 7 Kbuild syntax for exported headers - --- 7.1 no-export-headers - --- 7.2 generic-y - --- 7.3 generated-y - --- 7.4 mandatory-y - - === 8 Kbuild Variables - === 9 Makefile language - === 10 Credits - === 11 TODO - -=== 1 Overview - -The Makefiles have five parts: - - Makefile the top Makefile. - .config the kernel configuration file. - arch/$(ARCH)/Makefile the arch Makefile. - scripts/Makefile.* common rules etc. for all kbuild Makefiles. - kbuild Makefiles there are about 500 of these. - -The top Makefile reads the .config file, which comes from the kernel -configuration process. - -The top Makefile is responsible for building two major products: vmlinux -(the resident kernel image) and modules (any module files). -It builds these goals by recursively descending into the subdirectories of -the kernel source tree. -The list of subdirectories which are visited depends upon the kernel -configuration.

These people type commands such as -"make menuconfig" or "make". They usually do not read or edit -any kernel Makefiles (or any other source files). - -*Normal developers* are people who work on features such as device -drivers, file systems, and network protocols. These people need to -maintain the kbuild Makefiles for the subsystem they are -working on. In order to do this effectively, they need some overall -knowledge about the kernel Makefiles, plus detailed knowledge about the -public interface for kbuild. - -*Arch developers* are people who work on an entire architecture, such -as sparc or ia64. Arch developers need to know about the arch Makefile -as well as kbuild Makefiles. - -*Kbuild developers* are people who work on the kernel build system itself. -These people need to know about all aspects of the kernel Makefiles. - -This document is aimed towards normal developers and arch developers. - - -=== 3 The kbuild files - -Most Makefiles within the kernel are kbuild Makefiles that use the -kbuild infrastructure. This chapter introduces the syntax used in the -kbuild makefiles. -The preferred name for the kbuild files are 'Makefile' but 'Kbuild' can -be used and if both a 'Makefile' and a 'Kbuild' file exists, then the 'Kbuild' -file will be used. - -Section 3.1 "Goal definitions" is a quick intro, further chapters provide -more details, with real examples. - ---- 3.1 Goal definitions - - Goal definitions are the main part (heart) of the kbuild Makefile. - These lines define the files to be built, any special compilation - options, and any subdirectories to be entered recursively. - - The most simple kbuild makefile contains one line: - - Example: - obj-y += foo.o - - This tells kbuild that there is one object in that directory, named - foo.o. foo.o will be built from foo.c or foo.S. - - If foo.o shall be built as a module, the variable obj-m is used. - Therefore the following pattern is often used: - - Example: - obj-$(CONFIG_FOO) += foo.o - - $(CONFIG_FOO) evaluates to either y (for built-in) or m (for module). - If CONFIG_FOO is neither y nor m, then the file will not be compiled - nor linked. - ---- 3.2 Built-in object goals - obj-y - - The kbuild Makefile specifies object files for vmlinux - in the $(obj-y) lists. These lists depend on the kernel - configuration. - - Kbuild compiles all the $(obj-y) files. It then calls - "$(AR) rcSTP" to merge these files into one built-in.a file. - This is a thin archive without a symbol table. It will be later - linked into vmlinux by scripts/link-vmlinux.sh - - The order of files in $(obj-y) is significant. Duplicates in - the lists are allowed: the first instance will be linked into - built-in.a and succeeding instances will be ignored. - - Link order is significant, because certain functions - (module_init() / __initcall) will be called during boot in the - order they appear. So keep in mind that changing the link - order may e.g. change the order in which your SCSI - controllers are detected, and thus your disks are renumbered. - - Example: - #drivers/isdn/i4l/Makefile - # Makefile for the kernel ISDN subsystem and device drivers. - # Each configuration option enables a list of files. - obj-$(CONFIG_ISDN_I4L) += isdn.o - obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o - ---- 3.3 Loadable module goals - obj-m - - $(obj-m) specifies object files which are built as loadable - kernel modules. - - A module may be built from one source file or several source - files. In the case of one source file, the kbuild makefile - simply adds the file to $(obj-m). - - Example: - #drivers/isdn/i4l/Makefile - obj-$(CONFIG_ISDN_PPP_BSDCOMP) += isdn_bsdcomp.o - - Note: In this example $(CONFIG_ISDN_PPP_BSDCOMP) evaluates to 'm' - - If a kernel module is built from several source files, you specify - that you want to build a module in the same way as above; however, - kbuild needs to know which object files you want to build your - module from, so you have to tell it by setting a $(-y) - variable. - - Example: - #drivers/isdn/i4l/Makefile - obj-$(CONFIG_ISDN_I4L) += isdn.o - isdn-y := isdn_net_lib.o isdn_v110.o isdn_common.o - - In this example, the module name will be isdn.o. Kbuild will - compile the objects listed in $(isdn-y) and then run - "$(LD) -r" on the list of these files to generate isdn.o. - - Due to kbuild recognizing $(-y) for composite objects, - you can use the value of a CONFIG_ symbol to optionally include an - object file as part of a composite object. - - Example: - #fs/ext2/Makefile - obj-$(CONFIG_EXT2_FS) += ext2.o - ext2-y := balloc.o dir.o file.o ialloc.o inode.o ioctl.o \ - namei.o super.o symlink.o - ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o xattr_user.o \ - xattr_trusted.o - - In this example, xattr.o, xattr_user.o and xattr_trusted.o are only - part of the composite object ext2.o if $(CONFIG_EXT2_FS_XATTR) - evaluates to 'y'. - - Note: Of course, when you are building objects into the kernel, - the syntax above will also work. So, if you have CONFIG_EXT2_FS=y, - kbuild will build an ext2.o file for you out of the individual - parts and then link this into built-in.a, as you would expect. - ---- 3.4 Objects which export symbols - - No special notation is required in the makefiles for - modules exporting symbols. - ---- 3.5 Library file goals - lib-y - - Objects listed with obj-* are used for modules, or - combined in a built-in.a for that specific directory. - There is also the possibility to list objects that will - be included in a library, lib.a. - All objects listed with lib-y are combined in a single - library for that directory. - Objects that are listed in obj-y and additionally listed in - lib-y will not be included in the library, since they will - be accessible anyway. - For consistency, objects listed in lib-m will be included in lib.a. - - Note that the same kbuild makefile may list files to be built-in - and to be part of a library. Therefore the same directory - may contain both a built-in.a and a lib.a file. - - Example: - #arch/x86/lib/Makefile - lib-y := delay.o - - This will create a library lib.a based on delay.o. For kbuild to - actually recognize that there is a lib.a being built, the directory - shall be listed in libs-y. - See also "6.4 List directories to visit when descending". - - Use of lib-y is normally restricted to lib/ and arch/*/lib. - ---- 3.6 Descending down in directories - - A Makefile is only responsible for building objects in its own - directory. Files in subdirectories should be taken care of by - Makefiles in these subdirs. The build system will automatically - invoke make recursively in subdirectories, provided you let it know of - them. - - To do so, obj-y and obj-m are used. - ext2 lives in a separate directory, and the Makefile present in fs/ - tells kbuild to descend down using the following assignment. - - Example: - #fs/Makefile - obj-$(CONFIG_EXT2_FS) += ext2/ - - If CONFIG_EXT2_FS is set to either 'y' (built-in) or 'm' (modular) - the corresponding obj- variable will be set, and kbuild will descend - down in the ext2 directory. - Kbuild only uses this information to decide that it needs to visit - the directory, it is the Makefile in the subdirectory that - specifies what is modular and what is built-in. - - It is good practice to use a CONFIG_ variable when assigning directory - names. This allows kbuild to totally skip the directory if the - corresponding CONFIG_ option is neither 'y' nor 'm'. - ---- 3.7 Compilation flags - - ccflags-y, asflags-y and ldflags-y - These three flags apply only to the kbuild makefile in which they - are assigned. They are used for all the normal cc, as and ld - invocations happening during a recursive build. - Note: Flags with the same behaviour were previously named: - EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS. - They are still supported but their usage is deprecated. - - ccflags-y specifies options for compiling with $(CC). - - Example: - # drivers/acpi/acpica/Makefile - ccflags-y := -Os -D_LINUX -DBUILDING_ACPICA - ccflags-$(CONFIG_ACPI_DEBUG) += -DACPI_DEBUG_OUTPUT - - This variable is necessary because the top Makefile owns the - variable $(KBUILD_CFLAGS) and uses it for compilation flags for the - entire tree. - - asflags-y specifies options for assembling with $(AS). - - Example: - #arch/sparc/kernel/Makefile - asflags-y := -ansi - - ldflags-y specifies options for linking with $(LD). - - Example: - #arch/cris/boot/compressed/Makefile - ldflags-y += -T $(srctree)/$(src)/decompress_$(arch-y).lds - - subdir-ccflags-y, subdir-asflags-y - The two flags listed above are similar to ccflags-y and asflags-y. - The difference is that the subdir- variants have effect for the kbuild - file where they are present and all subdirectories. - Options specified using subdir-* are added to the commandline before - the options specified using the non-subdir variants. - - Example: - subdir-ccflags-y := -Werror - - CFLAGS_$@, AFLAGS_$@ - - CFLAGS_$@ and AFLAGS_$@ only apply to commands in current - kbuild makefile. - - $(CFLAGS_$@) specifies per-file options for $(CC). The $@ - part has a literal value which specifies the file that it is for. - - Example: - # drivers/scsi/Makefile - CFLAGS_aha152x.o = -DAHA152X_STAT -DAUTOCONF - CFLAGS_gdth.o = # -DDEBUG_GDTH=2 -D__SERIAL__ -D__COM2__ \ - -DGDTH_STATISTICS - - These two lines specify compilation flags for aha152x.o and gdth.o. - - $(AFLAGS_$@) is a similar feature for source files in assembly - languages. - - Example: - # arch/arm/kernel/Makefile - AFLAGS_head.o := -DTEXT_OFFSET=$(TEXT_OFFSET) - AFLAGS_crunch-bits.o := -Wa,-mcpu=ep9312 - AFLAGS_iwmmxt.o := -Wa,-mcpu=iwmmxt - - ---- 3.9 Dependency tracking - - Kbuild tracks dependencies on the following: - 1) All prerequisite files (both *.c and *.h) - 2) CONFIG_ options used in all prerequisite files - 3) Command-line used to compile target - - Thus, if you change an option to $(CC) all affected files will - be re-compiled. - ---- 3.10 Special Rules - - Special rules are used when the kbuild infrastructure does - not provide the required support. A typical example is - header files generated during the build process. - Another example are the architecture-specific Makefiles which - need special rules to prepare boot images etc. - - Special rules are written as normal Make rules. - Kbuild is not executing in the directory where the Makefile is - located, so all special rules shall provide a relative - path to prerequisite files and target files. - - Two variables are used when defining special rules: - - $(src) - $(src) is a relative path which points to the directory - where the Makefile is located. Always use $(src) when - referring to files located in the src tree. - - $(obj) - $(obj) is a relative path which points to the directory - where the target is saved. Always use $(obj) when - referring to generated files. - - Example: - #drivers/scsi/Makefile - $(obj)/53c8xx_d.h: $(src)/53c7,8xx.scr $(src)/script_asm.pl - $(CPP) -DCHIP=810 - < $< | ... $(src)/script_asm.pl - - This is a special rule, following the normal syntax - required by make. - The target file depends on two prerequisite files. References - to the target file are prefixed with $(obj), references - to prerequisites are referenced with $(src) (because they are not - generated files). - - $(kecho) - echoing information to user in a rule is often a good practice - but when execution "make -s" one does not expect to see any output - except for warnings/errors. - To support this kbuild defines $(kecho) which will echo out the - text following $(kecho) to stdout except if "make -s" is used. - - Example: - #arch/blackfin/boot/Makefile - $(obj)/vmImage: $(obj)/vmlinux.gz - $(call if_changed,uimage) - @$(kecho) 'Kernel: $@ is ready' - - ---- 3.11 $(CC) support functions - - The kernel may be built with several different versions of - $(CC), each supporting a unique set of features and options. - kbuild provides basic support to check for valid options for $(CC). - $(CC) is usually the gcc compiler, but other alternatives are - available. - - as-option - as-option is used to check if $(CC) -- when used to compile - assembler (*.S) files -- supports the given option. An optional - second option may be specified if the first option is not supported. - - Example: - #arch/sh/Makefile - cflags-y += $(call as-option,-Wa$(comma)-isa=$(isa-y),) - - In the above example, cflags-y will be assigned the option - -Wa$(comma)-isa=$(isa-y) if it is supported by $(CC). - The second argument is optional, and if supplied will be used - if first argument is not supported. - - as-instr - as-instr checks if the assembler reports a specific instruction - and then outputs either option1 or option2 - C escapes are supported in the test instruction - Note: as-instr-option uses KBUILD_AFLAGS for $(AS) options - - cc-option - cc-option is used to check if $(CC) supports a given option, and if - not supported to use an optional second option. - - Example: - #arch/x86/Makefile - cflags-y += $(call cc-option,-march=pentium-mmx,-march=i586) - - In the above example, cflags-y will be assigned the option - -march=pentium-mmx if supported by $(CC), otherwise -march=i586. - The second argument to cc-option is optional, and if omitted, - cflags-y will be assigned no value if first option is not supported. - Note: cc-option uses KBUILD_CFLAGS for $(CC) options - - cc-option-yn - cc-option-yn is used to check if gcc supports a given option - and return 'y' if supported, otherwise 'n'. - - Example: - #arch/ppc/Makefile - biarch := $(call cc-option-yn, -m32) - aflags-$(biarch) += -a32 - cflags-$(biarch) += -m32 - - In the above example, $(biarch) is set to y if $(CC) supports the -m32 - option. When $(biarch) equals 'y', the expanded variables $(aflags-y) - and $(cflags-y) will be assigned the values -a32 and -m32, - respectively. - Note: cc-option-yn uses KBUILD_CFLAGS for $(CC) options - - cc-disable-warning - cc-disable-warning checks if gcc supports a given warning and returns - the commandline switch to disable it. This special function is needed, - because gcc 4.4 and later accept any unknown -Wno-* option and only - warn about it if there is another warning in the source file. - - Example: - KBUILD_CFLAGS += $(call cc-disable-warning, unused-but-set-variable) - - In the above example, -Wno-unused-but-set-variable will be added to - KBUILD_CFLAGS only if gcc really accepts it. - - cc-ifversion - cc-ifversion tests the version of $(CC) and equals the fourth parameter - if version expression is true, or the fifth (if given) if the version - expression is false. - - Example: - #fs/reiserfs/Makefile - ccflags-y := $(call cc-ifversion, -lt, 0402, -O1) - - In this example, ccflags-y will be assigned the value -O1 if the - $(CC) version is less than 4.2. - cc-ifversion takes all the shell operators: - -eq, -ne, -lt, -le, -gt, and -ge - The third parameter may be a text as in this example, but it may also - be an expanded variable or a macro. - - cc-cross-prefix - cc-cross-prefix is used to check if there exists a $(CC) in path with - one of the listed prefixes. The first prefix where there exist a - prefix$(CC) in the PATH is returned - and if no prefix$(CC) is found - then nothing is returned. - Additional prefixes are separated by a single space in the - call of cc-cross-prefix. - This functionality is useful for architecture Makefiles that try - to set CROSS_COMPILE to well-known values but may have several - values to select between. - It is recommended only to try to set CROSS_COMPILE if it is a cross - build (host arch is different from target arch). And if CROSS_COMPILE - is already set then leave it with the old value. - - Example: - #arch/m68k/Makefile - ifneq ($(SUBARCH),$(ARCH)) - ifeq ($(CROSS_COMPILE),) - CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu-) - endif - endif - ---- 3.12 $(LD) support functions - - ld-option - ld-option is used to check if $(LD) supports the supplied option. - ld-option takes two options as arguments. - The second argument is an optional option that can be used if the - first option is not supported by $(LD). - - Example: - #Makefile - LDFLAGS_vmlinux += $(call ld-option, -X) - - -=== 4 Host Program support - -Kbuild supports building executables on the host for use during the -compilation stage. -Two steps are required in order to use a host executable. - -The first step is to tell kbuild that a host program exists. This is -done utilising the variable hostprogs-y. - -The second step is to add an explicit dependency to the executable. -This can be done in two ways. Either add the dependency in a rule, -or utilise the variable $(always). -Both possibilities are described in the following. - ---- 4.1 Simple Host Program - - In some cases there is a need to compile and run a program on the - computer where the build is running. - The following line tells kbuild that the program bin2hex shall be - built on the build host. - - Example: - hostprogs-y := bin2hex - - Kbuild assumes in the above example that bin2hex is made from a single - c-source file named bin2hex.c located in the same directory as - the Makefile. - ---- 4.2 Composite Host Programs - - Host programs can be made up based on composite objects. - The syntax used to define composite objects for host programs is - similar to the syntax used for kernel objects. - $(-objs) lists all objects used to link the final - executable. - - Example: - #scripts/lxdialog/Makefile - hostprogs-y := lxdialog - lxdialog-objs := checklist.o lxdialog.o - - Objects with extension .o are compiled from the corresponding .c - files. In the above example, checklist.c is compiled to checklist.o - and lxdialog.c is compiled to lxdialog.o. - Finally, the two .o files are linked to the executable, lxdialog. - Note: The syntax -y is not permitted for host-programs. - ---- 4.3 Using C++ for host programs - - kbuild offers support for host programs written in C++. This was - introduced solely to support kconfig, and is not recommended - for general use. - - Example: - #scripts/kconfig/Makefile - hostprogs-y := qconf - qconf-cxxobjs := qconf.o - - In the example above the executable is composed of the C++ file - qconf.cc - identified by $(qconf-cxxobjs). - - If qconf is composed of a mixture of .c and .cc files, then an - additional line can be used to identify this. - - Example: - #scripts/kconfig/Makefile - hostprogs-y := qconf - qconf-cxxobjs := qconf.o - qconf-objs := check.o - ---- 4.4 Controlling compiler options for host programs - - When compiling host programs, it is possible to set specific flags. - The programs will always be compiled utilising $(HOSTCC) passed - the options specified in $(KBUILD_HOSTCFLAGS). - To set flags that will take effect for all host programs created - in that Makefile, use the variable HOST_EXTRACFLAGS. - - Example: - #scripts/lxdialog/Makefile - HOST_EXTRACFLAGS += -I/usr/include/ncurses - - To set specific flags for a single file the following construction - is used: - - Example: - #arch/ppc64/boot/Makefile - HOSTCFLAGS_piggyback.o := -DKERNELBASE=$(KERNELBASE) - - It is also possible to specify additional options to the linker. - - Example: - #scripts/kconfig/Makefile - HOSTLDLIBS_qconf := -L$(QTDIR)/lib - - When linking qconf, it will be passed the extra option - "-L$(QTDIR)/lib". - ---- 4.5 When host programs are actually built - - Kbuild will only build host-programs when they are referenced - as a prerequisite. - This is possible in two ways: - - (1) List the prerequisite explicitly in a special rule. - - Example: - #drivers/pci/Makefile - hostprogs-y := gen-devlist - $(obj)/devlist.h: $(src)/pci.ids $(obj)/gen-devlist - ( cd $(obj); ./gen-devlist ) < $< - - The target $(obj)/devlist.h will not be built before - $(obj)/gen-devlist is updated. Note that references to - the host programs in special rules must be prefixed with $(obj). - - (2) Use $(always) - When there is no suitable special rule, and the host program - shall be built when a makefile is entered, the $(always) - variable shall be used. - - Example: - #scripts/lxdialog/Makefile - hostprogs-y := lxdialog - always := $(hostprogs-y) - - This will tell kbuild to build lxdialog even if not referenced in - any rule. - ---- 4.6 Using hostprogs-$(CONFIG_FOO) - - A typical pattern in a Kbuild file looks like this: - - Example: - #scripts/Makefile - hostprogs-$(CONFIG_KALLSYMS) += kallsyms - - Kbuild knows about both 'y' for built-in and 'm' for module. - So if a config symbol evaluates to 'm', kbuild will still build - the binary. In other words, Kbuild handles hostprogs-m exactly - like hostprogs-y. But only hostprogs-y is recommended to be used - when no CONFIG symbols are involved. - -=== 5 Kbuild clean infrastructure - -"make clean" deletes most generated files in the obj tree where the kernel -is compiled. This includes generated files such as host programs. -Kbuild knows targets listed in $(hostprogs-y), $(hostprogs-m), $(always), -$(extra-y) and $(targets). They are all deleted during "make clean". -Files matching the patterns "*.[oas]", "*.ko", plus some additional files -generated by kbuild are deleted all over the kernel src tree when -"make clean" is executed. - -Additional files can be specified in kbuild makefiles by use of $(clean-files). - - Example: - #lib/Makefile - clean-files := crc32table.h - -When executing "make clean", the file "crc32table.h" will be deleted. -Kbuild will assume files to be in the same relative directory as the -Makefile, except if prefixed with $(objtree). - -To delete a directory hierarchy use: - - Example: - #scripts/package/Makefile - clean-dirs := $(objtree)/debian/ - -This will delete the directory debian in the toplevel directory, including all -subdirectories. - -To exclude certain files from make clean, use the $(no-clean-files) variable. -This is only a special case used in the top level Kbuild file: - - Example: - #Kbuild - no-clean-files := $(bounds-file) $(offsets-file) - -Usually kbuild descends down in subdirectories due to "obj-* := dir/", -but in the architecture makefiles where the kbuild infrastructure -is not sufficient this sometimes needs to be explicit. - - Example: - #arch/x86/boot/Makefile - subdir- := compressed/ - -The above assignment instructs kbuild to descend down in the -directory compressed/ when "make clean" is executed. - -To support the clean infrastructure in the Makefiles that build the -final bootimage there is an optional target named archclean: - - Example: - #arch/x86/Makefile - archclean: - $(Q)$(MAKE) $(clean)=arch/x86/boot - -When "make clean" is executed, make will descend down in arch/x86/boot, -and clean as usual. The Makefile located in arch/x86/boot/ may use -the subdir- trick to descend further down. - -Note 1: arch/$(ARCH)/Makefile cannot use "subdir-", because that file is -included in the top level makefile, and the kbuild infrastructure -is not operational at that point. - -Note 2: All directories listed in core-y, libs-y, drivers-y and net-y will -be visited during "make clean". - -=== 6 Architecture Makefiles - -The top level Makefile sets up the environment and does the preparation, -before starting to descend down in the individual directories. -The top level makefile contains the generic part, whereas -arch/$(ARCH)/Makefile contains what is required to set up kbuild -for said architecture. -To do so, arch/$(ARCH)/Makefile sets up a number of variables and defines -a few targets. - -When kbuild executes, the following steps are followed (roughly): -1) Configuration of the kernel => produce .config -2) Store kernel version in include/linux/version.h -3) Updating all other prerequisites to the target prepare: - - Additional prerequisites are specified in arch/$(ARCH)/Makefile -4) Recursively descend down in all directories listed in - init-* core* drivers-* net-* libs-* and build all targets. - - The values of the above variables are expanded in arch/$(ARCH)/Makefile. -5) All object files are then linked and the resulting file vmlinux is - located at the root of the obj tree. - The very first objects linked are listed in head-y, assigned by - arch/$(ARCH)/Makefile. -6) Finally, the architecture-specific part does any required post processing - and builds the final bootimage. - - This includes building boot records - - Preparing initrd images and the like - - ---- 6.1 Set variables to tweak the build to the architecture - - LDFLAGS Generic $(LD) options - - Flags used for all invocations of the linker. - Often specifying the emulation is sufficient. - - Example: - #arch/s390/Makefile - LDFLAGS := -m elf_s390 - Note: ldflags-y can be used to further customise - the flags used. See chapter 3.7. - - LDFLAGS_vmlinux Options for $(LD) when linking vmlinux - - LDFLAGS_vmlinux is used to specify additional flags to pass to - the linker when linking the final vmlinux image. - LDFLAGS_vmlinux uses the LDFLAGS_$@ support. - - Example: - #arch/x86/Makefile - LDFLAGS_vmlinux := -e stext - - OBJCOPYFLAGS objcopy flags - - When $(call if_changed,objcopy) is used to translate a .o file, - the flags specified in OBJCOPYFLAGS will be used. - $(call if_changed,objcopy) is often used to generate raw binaries on - vmlinux. - - Example: - #arch/s390/Makefile - OBJCOPYFLAGS := -O binary - - #arch/s390/boot/Makefile - $(obj)/image: vmlinux FORCE - $(call if_changed,objcopy) - - In this example, the binary $(obj)/image is a binary version of - vmlinux. The usage of $(call if_changed,xxx) will be described later. - - KBUILD_AFLAGS $(AS) assembler flags - - Default value - see top level Makefile - Append or modify as required per architecture. - - Example: - #arch/sparc64/Makefile - KBUILD_AFLAGS += -m64 -mcpu=ultrasparc - - KBUILD_CFLAGS $(CC) compiler flags - - Default value - see top level Makefile - Append or modify as required per architecture. - - Often, the KBUILD_CFLAGS variable depends on the configuration. - - Example: - #arch/x86/boot/compressed/Makefile - cflags-$(CONFIG_X86_32) := -march=i386 - cflags-$(CONFIG_X86_64) := -mcmodel=small - KBUILD_CFLAGS += $(cflags-y) - - Many arch Makefiles dynamically run the target C compiler to - probe supported options: - - #arch/x86/Makefile - - ... - cflags-$(CONFIG_MPENTIUMII) += $(call cc-option,\ - -march=pentium2,-march=i686) - ... - # Disable unit-at-a-time mode ... - KBUILD_CFLAGS += $(call cc-option,-fno-unit-at-a-time) - ... - - - The first example utilises the trick that a config option expands - to 'y' when selected. - - KBUILD_AFLAGS_KERNEL $(AS) options specific for built-in - - $(KBUILD_AFLAGS_KERNEL) contains extra C compiler flags used to compile - resident kernel code. - - KBUILD_AFLAGS_MODULE Options for $(AS) when building modules - - $(KBUILD_AFLAGS_MODULE) is used to add arch-specific options that - are used for $(AS). - From commandline AFLAGS_MODULE shall be used (see kbuild.txt). - - KBUILD_CFLAGS_KERNEL $(CC) options specific for built-in - - $(KBUILD_CFLAGS_KERNEL) contains extra C compiler flags used to compile - resident kernel code. - - KBUILD_CFLAGS_MODULE Options for $(CC) when building modules - - $(KBUILD_CFLAGS_MODULE) is used to add arch-specific options that - are used for $(CC). - From commandline CFLAGS_MODULE shall be used (see kbuild.txt). - - KBUILD_LDFLAGS_MODULE Options for $(LD) when linking modules - - $(KBUILD_LDFLAGS_MODULE) is used to add arch-specific options - used when linking modules. This is often a linker script. - From commandline LDFLAGS_MODULE shall be used (see kbuild.txt). - - KBUILD_ARFLAGS Options for $(AR) when creating archives - - $(KBUILD_ARFLAGS) set by the top level Makefile to "D" (deterministic - mode) if this option is supported by $(AR). - - ARCH_CPPFLAGS, ARCH_AFLAGS, ARCH_CFLAGS Overrides the kbuild defaults - - These variables are appended to the KBUILD_CPPFLAGS, - KBUILD_AFLAGS, and KBUILD_CFLAGS, respectively, after the - top-level Makefile has set any other flags. This provides a - means for an architecture to override the defaults. - - ---- 6.2 Add prerequisites to archheaders: - - The archheaders: rule is used to generate header files that - may be installed into user space by "make header_install" or - "make headers_install_all". In order to support - "make headers_install_all", this target has to be able to run - on an unconfigured tree, or a tree configured for another - architecture. - - It is run before "make archprepare" when run on the - architecture itself. - - ---- 6.3 Add prerequisites to archprepare: - - The archprepare: rule is used to list prerequisites that need to be - built before starting to descend down in the subdirectories. - This is usually used for header files containing assembler constants. - - Example: - #arch/arm/Makefile - archprepare: maketools - - In this example, the file target maketools will be processed - before descending down in the subdirectories. - See also chapter XXX-TODO that describe how kbuild supports - generating offset header files. - - ---- 6.4 List directories to visit when descending - - An arch Makefile cooperates with the top Makefile to define variables - which specify how to build the vmlinux file. Note that there is no - corresponding arch-specific section for modules; the module-building - machinery is all architecture-independent. - - - head-y, init-y, core-y, libs-y, drivers-y, net-y - - $(head-y) lists objects to be linked first in vmlinux. - $(libs-y) lists directories where a lib.a archive can be located. - The rest list directories where a built-in.a object file can be - located. - - $(init-y) objects will be located after $(head-y). - Then the rest follows in this order: - $(core-y), $(libs-y), $(drivers-y) and $(net-y). - - The top level Makefile defines values for all generic directories, - and arch/$(ARCH)/Makefile only adds architecture-specific directories. - - Example: - #arch/sparc64/Makefile - core-y += arch/sparc64/kernel/ - libs-y += arch/sparc64/prom/ arch/sparc64/lib/ - drivers-$(CONFIG_OPROFILE) += arch/sparc64/oprofile/ - - ---- 6.5 Architecture-specific boot images - - An arch Makefile specifies goals that take the vmlinux file, compress - it, wrap it in bootstrapping code, and copy the resulting files - somewhere. This includes various kinds of installation commands. - The actual goals are not standardized across architectures. - - It is common to locate any additional processing in a boot/ - directory below arch/$(ARCH)/. - - Kbuild does not provide any smart way to support building a - target specified in boot/. Therefore arch/$(ARCH)/Makefile shall - call make manually to build a target in boot/. - - The recommended approach is to include shortcuts in - arch/$(ARCH)/Makefile, and use the full path when calling down - into the arch/$(ARCH)/boot/Makefile. - - Example: - #arch/x86/Makefile - boot := arch/x86/boot - bzImage: vmlinux - $(Q)$(MAKE) $(build)=$(boot) $(boot)/$@ - - "$(Q)$(MAKE) $(build)=" is the recommended way to invoke - make in a subdirectory. - - There are no rules for naming architecture-specific targets, - but executing "make help" will list all relevant targets. - To support this, $(archhelp) must be defined. - - Example: - #arch/x86/Makefile - define archhelp - echo '* bzImage - Image (arch/$(ARCH)/boot/bzImage)' - endif - - When make is executed without arguments, the first goal encountered - will be built. In the top level Makefile the first goal present - is all:. - An architecture shall always, per default, build a bootable image. - In "make help", the default goal is highlighted with a '*'. - Add a new prerequisite to all: to select a default goal different - from vmlinux. - - Example: - #arch/x86/Makefile - all: bzImage - - When "make" is executed without arguments, bzImage will be built. - ---- 6.6 Building non-kbuild targets - - extra-y - - extra-y specifies additional targets created in the current - directory, in addition to any targets specified by obj-*. - - Listing all targets in extra-y is required for two purposes: - 1) Enable kbuild to check changes in command lines - - When $(call if_changed,xxx) is used - 2) kbuild knows what files to delete during "make clean" - - Example: - #arch/x86/kernel/Makefile - extra-y := head.o init_task.o - - In this example, extra-y is used to list object files that - shall be built, but shall not be linked as part of built-in.a. - - ---- 6.7 Commands useful for building a boot image - - Kbuild provides a few macros that are useful when building a - boot image. - - if_changed - - if_changed is the infrastructure used for the following commands. - - Usage: - target: source(s) FORCE - $(call if_changed,ld/objcopy/gzip/...) - - When the rule is evaluated, it is checked to see if any files - need an update, or the command line has changed since the last - invocation. The latter will force a rebuild if any options - to the executable have changed. - Any target that utilises if_changed must be listed in $(targets), - otherwise the command line check will fail, and the target will - always be built. - Assignments to $(targets) are without $(obj)/ prefix. - if_changed may be used in conjunction with custom commands as - defined in 6.8 "Custom kbuild commands". - - Note: It is a typical mistake to forget the FORCE prerequisite. - Another common pitfall is that whitespace is sometimes - significant; for instance, the below will fail (note the extra space - after the comma): - target: source(s) FORCE - #WRONG!# $(call if_changed, ld/objcopy/gzip/...) - - Note: if_changed should not be used more than once per target. - It stores the executed command in a corresponding .cmd - file and multiple calls would result in overwrites and - unwanted results when the target is up to date and only the - tests on changed commands trigger execution of commands. - - ld - Link target. Often, LDFLAGS_$@ is used to set specific options to ld. - - Example: - #arch/x86/boot/Makefile - LDFLAGS_bootsect := -Ttext 0x0 -s --oformat binary - LDFLAGS_setup := -Ttext 0x0 -s --oformat binary -e begtext - - targets += setup setup.o bootsect bootsect.o - $(obj)/setup $(obj)/bootsect: %: %.o FORCE - $(call if_changed,ld) - - In this example, there are two possible targets, requiring different - options to the linker. The linker options are specified using the - LDFLAGS_$@ syntax - one for each potential target. - $(targets) are assigned all potential targets, by which kbuild knows - the targets and will: - 1) check for commandline changes - 2) delete target during make clean - - The ": %: %.o" part of the prerequisite is a shorthand that - frees us from listing the setup.o and bootsect.o files. - Note: It is a common mistake to forget the "targets :=" assignment, - resulting in the target file being recompiled for no - obvious reason. - - objcopy - Copy binary. Uses OBJCOPYFLAGS usually specified in - arch/$(ARCH)/Makefile. - OBJCOPYFLAGS_$@ may be used to set additional options. - - gzip - Compress target. Use maximum compression to compress target. - - Example: - #arch/x86/boot/compressed/Makefile - $(obj)/vmlinux.bin.gz: $(vmlinux.bin.all-y) FORCE - $(call if_changed,gzip) - - dtc - Create flattened device tree blob object suitable for linking - into vmlinux. Device tree blobs linked into vmlinux are placed - in an init section in the image. Platform code *must* copy the - blob to non-init memory prior to calling unflatten_device_tree(). - - To use this command, simply add *.dtb into obj-y or targets, or make - some other target depend on %.dtb - - A central rule exists to create $(obj)/%.dtb from $(src)/%.dts; - architecture Makefiles do no need to explicitly write out that rule. - - Example: - targets += $(dtb-y) - DTC_FLAGS ?= -p 1024 - ---- 6.8 Custom kbuild commands - - When kbuild is executing with KBUILD_VERBOSE=0, then only a shorthand - of a command is normally displayed. - To enable this behaviour for custom commands kbuild requires - two variables to be set: - quiet_cmd_ - what shall be echoed - cmd_ - the command to execute - - Example: - # - quiet_cmd_image = BUILD $@ - cmd_image = $(obj)/tools/build $(BUILDFLAGS) \ - $(obj)/vmlinux.bin > $@ - - targets += bzImage - $(obj)/bzImage: $(obj)/vmlinux.bin $(obj)/tools/build FORCE - $(call if_changed,image) - @echo 'Kernel: $@ is ready' - - When updating the $(obj)/bzImage target, the line - - BUILD arch/x86/boot/bzImage - - will be displayed with "make KBUILD_VERBOSE=0". - - ---- 6.9 Preprocessing linker scripts - - When the vmlinux image is built, the linker script - arch/$(ARCH)/kernel/vmlinux.lds is used. - The script is a preprocessed variant of the file vmlinux.lds.S - located in the same directory. - kbuild knows .lds files and includes a rule *lds.S -> *lds. - - Example: - #arch/x86/kernel/Makefile - always := vmlinux.lds - - #Makefile - export CPPFLAGS_vmlinux.lds += -P -C -U$(ARCH) - - The assignment to $(always) is used to tell kbuild to build the - target vmlinux.lds. - The assignment to $(CPPFLAGS_vmlinux.lds) tells kbuild to use the - specified options when building the target vmlinux.lds. - - When building the *.lds target, kbuild uses the variables: - KBUILD_CPPFLAGS : Set in top-level Makefile - cppflags-y : May be set in the kbuild makefile - CPPFLAGS_$(@F) : Target-specific flags. - Note that the full filename is used in this - assignment. - - The kbuild infrastructure for *lds files is used in several - architecture-specific files. - ---- 6.10 Generic header files - - The directory include/asm-generic contains the header files - that may be shared between individual architectures. - The recommended approach how to use a generic header file is - to list the file in the Kbuild file. - See "7.2 generic-y" for further info on syntax etc. - ---- 6.11 Post-link pass - - If the file arch/xxx/Makefile.postlink exists, this makefile - will be invoked for post-link objects (vmlinux and modules.ko) - for architectures to run post-link passes on. Must also handle - the clean target. - - This pass runs after kallsyms generation. If the architecture - needs to modify symbol locations, rather than manipulate the - kallsyms, it may be easier to add another postlink target for - .tmp_vmlinux? targets to be called from link-vmlinux.sh. - - For example, powerpc uses this to check relocation sanity of - the linked vmlinux file. - -=== 7 Kbuild syntax for exported headers - -The kernel includes a set of headers that is exported to userspace. -Many headers can be exported as-is but other headers require a -minimal pre-processing before they are ready for user-space. -The pre-processing does: -- drop kernel-specific annotations -- drop include of compiler.h -- drop all sections that are kernel internal (guarded by ifdef __KERNEL__) - -All headers under include/uapi/, include/generated/uapi/, -arch//include/uapi/ and arch//include/generated/uapi/ -are exported. - -A Kbuild file may be defined under arch//include/uapi/asm/ and -arch//include/asm/ to list asm files coming from asm-generic. -See subsequent chapter for the syntax of the Kbuild file. - ---- 7.1 no-export-headers - - no-export-headers is essentially used by include/uapi/linux/Kbuild to - avoid exporting specific headers (e.g. kvm.h) on architectures that do - not support it. It should be avoided as much as possible. - ---- 7.2 generic-y - - If an architecture uses a verbatim copy of a header from - include/asm-generic then this is listed in the file - arch/$(ARCH)/include/asm/Kbuild like this: - - Example: - #arch/x86/include/asm/Kbuild - generic-y += termios.h - generic-y += rtc.h - - During the prepare phase of the build a wrapper include - file is generated in the directory: - - arch/$(ARCH)/include/generated/asm - - When a header is exported where the architecture uses - the generic header a similar wrapper is generated as part - of the set of exported headers in the directory: - - usr/include/asm - - The generated wrapper will in both cases look like the following: - - Example: termios.h - #include - ---- 7.3 generated-y - - If an architecture generates other header files alongside generic-y - wrappers, generated-y specifies them. - - This prevents them being treated as stale asm-generic wrappers and - removed. - - Example: - #arch/x86/include/asm/Kbuild - generated-y += syscalls_32.h - ---- 7.4 mandatory-y - - mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild - to define the minimum set of ASM headers that all architectures must have. - - This works like optional generic-y. If a mandatory header is missing - in arch/$(ARCH)/include/(uapi/)/asm, Kbuild will automatically generate - a wrapper of the asm-generic one. - - The convention is to list one subdir per line and - preferably in alphabetic order. - -=== 8 Kbuild Variables - -The top Makefile exports the following variables: - - VERSION, PATCHLEVEL, SUBLEVEL, EXTRAVERSION - - These variables define the current kernel version. A few arch - Makefiles actually use these values directly; they should use - $(KERNELRELEASE) instead. - - $(VERSION), $(PATCHLEVEL), and $(SUBLEVEL) define the basic - three-part version number, such as "2", "4", and "0".

Modules must use +kbuild to stay compatible with changes in the build infrastructure and +to pick up the right flags to "gcc." Functionality for building modules +both in-tree and out-of-tree is provided. The method for building +either is similar, and all modules are initially developed and built +out-of-tree. + +Covered in this document is information aimed at developers interested +in building out-of-tree (or "external") modules. The author of an +external module should supply a makefile that hides most of the +complexity, so one only has to type "make" to build the module. This is +easily accomplished, and a complete example will be presented in +section 3. + + +2. How to Build External Modules +================================ + +To build external modules, you must have a prebuilt kernel available +that contains the configuration and header files used in the build. +Also, the kernel must have been built with modules enabled. If you are +using a distribution kernel, there will be a package for the kernel you +are running provided by your distribution. + +An alternative is to use the "make" target "modules_prepare." This will +make sure the kernel contains the information required. The target +exists solely as a simple way to prepare a kernel source tree for +building external modules. + +NOTE: "modules_prepare" will not build Module.symvers even if +CONFIG_MODVERSIONS is set; therefore, a full kernel build needs to be +executed to make module versioning work. + +2.1 Command Syntax +================== + + The command to build an external module is:: + + $ make -C M=$PWD + + The kbuild system knows that an external module is being built + due to the "M=" option given in the command. + + To build against the running kernel use:: + + $ make -C /lib/modules/`uname -r`/build M=$PWD + + Then to install the module(s) just built, add the target + "modules_install" to the command:: + + $ make -C /lib/modules/`uname -r`/build M=$PWD modules_install + +2.2 Options +=========== + + ($KDIR refers to the path of the kernel source directory.) + + make -C $KDIR M=$PWD + + -C $KDIR + The directory where the kernel source is located. + "make" will actually change to the specified directory + when executing and will change back when finished. + + M=$PWD + Informs kbuild that an external module is being built. + The value given to "M" is the absolute path of the + directory where the external module (kbuild file) is + located. + +2.3 Targets +=========== + + When building an external module, only a subset of the "make" + targets are available. + + make -C $KDIR M=$PWD [target] + + The default will build the module(s) located in the current + directory, so a target does not need to be specified. All + output files will also be generated in this directory. No + attempts are made to update the kernel source, and it is a + precondition that a successful "make" has been executed for the + kernel. + + modules + The default target for external modules. It has the + same functionality as if no target was specified. See + description above. + + modules_install + Install the external module(s). The default location is + /lib/modules//extra/, but a prefix may + be added with INSTALL_MOD_PATH (discussed in section 5). + + clean + Remove all generated files in the module directory only. + + help + List the available targets for external modules. + +2.4 Building Separate Files +=========================== + + It is possible to build single files that are part of a module. + This works equally well for the kernel, a module, and even for + external modules. + + Example (The module foo.ko, consist of bar.o and baz.o):: + + make -C $KDIR M=$PWD bar.lst + make -C $KDIR M=$PWD baz.o + make -C $KDIR M=$PWD foo.ko + make -C $KDIR M=$PWD ./ + + +3. Creating a Kbuild File for an External Module +================================================ + +In the last section we saw the command to build a module for the +running kernel. The module is not actually built, however, because a +build file is required. Contained in this file will be the name of +the module(s) being built, along with the list of requisite source +files. The file may be as simple as a single line:: + + obj-m := .o + +The kbuild system will build .o from .c, +and, after linking, will result in the kernel module .ko. +The above line can be put in either a "Kbuild" file or a "Makefile." +When the module is built from multiple sources, an additional line is +needed listing the files:: + + -y := .o .o ... + +NOTE: Further documentation describing the syntax used by kbuild is +located in Documentation/kbuild/makefiles.rst. + +The examples below demonstrate how to create a build file for the +module 8123.ko, which is built from the following files:: + + 8123_if.c + 8123_if.h + 8123_pci.c + 8123_bin.o_shipped <= Binary blob + +--- 3.1 Shared Makefile + + An external module always includes a wrapper makefile that + supports building the module using "make" with no arguments. + This target is not used by kbuild; it is only for convenience. + Additional functionality, such as test targets, can be included + but should be filtered out from kbuild due to possible name + clashes. + + Example 1:: + + --> filename: Makefile + ifneq ($(KERNELRELEASE),) + # kbuild part of makefile + obj-m := 8123.o + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + else + # normal makefile + KDIR ?= /lib/modules/`uname -r`/build + + default: + $(MAKE) -C $(KDIR) M=$$PWD + + # Module specific targets + genbin: + echo "X" > 8123_bin.o_shipped + + endif + + The check for KERNELRELEASE is used to separate the two parts + of the makefile. In the example, kbuild will only see the two + assignments, whereas "make" will see everything except these + two assignments. This is due to two passes made on the file: + the first pass is by the "make" instance run on the command + line; the second pass is by the kbuild system, which is + initiated by the parameterized "make" in the default target. + +3.2 Separate Kbuild File and Makefile +------------------------------------- + + In newer versions of the kernel, kbuild will first look for a + file named "Kbuild," and only if that is not found, will it + then look for a makefile. Utilizing a "Kbuild" file allows us + to split up the makefile from example 1 into two files: + + Example 2:: + + --> filename: Kbuild + obj-m := 8123.o + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + --> filename: Makefile + KDIR ?= /lib/modules/`uname -r`/build + + default: + $(MAKE) -C $(KDIR) M=$$PWD + + # Module specific targets + genbin: + echo "X" > 8123_bin.o_shipped + + The split in example 2 is questionable due to the simplicity of + each file; however, some external modules use makefiles + consisting of several hundred lines, and here it really pays + off to separate the kbuild part from the rest. + + The next example shows a backward compatible version. + + Example 3:: + + --> filename: Kbuild + obj-m := 8123.o + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + --> filename: Makefile + ifneq ($(KERNELRELEASE),) + # kbuild part of makefile + include Kbuild + + else + # normal makefile + KDIR ?= /lib/modules/`uname -r`/build + + default: + $(MAKE) -C $(KDIR) M=$$PWD + + # Module specific targets + genbin: + echo "X" > 8123_bin.o_shipped + + endif + + Here the "Kbuild" file is included from the makefile. This + allows an older version of kbuild, which only knows of + makefiles, to be used when the "make" and kbuild parts are + split into separate files. + +3.3 Binary Blobs +---------------- + + Some external modules need to include an object file as a blob. + kbuild has support for this, but requires the blob file to be + named _shipped. When the kbuild rules kick in, a copy + of _shipped is created with _shipped stripped off, + giving us . This shortened filename can be used in + the assignment to the module. + + Throughout this section, 8123_bin.o_shipped has been used to + build the kernel module 8123.ko; it has been included as + 8123_bin.o:: + + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + Although there is no distinction between the ordinary source + files and the binary file, kbuild will pick up different rules + when creating the object file for the module. + +3.4 Building Multiple Modules +============================= + + kbuild supports building multiple modules with a single build + file. For example, if you wanted to build two modules, foo.ko + and bar.ko, the kbuild lines would be:: + + obj-m := foo.o bar.o + foo-y := + bar-y := + + It is that simple! + + +4. Include Files +================ + +Within the kernel, header files are kept in standard locations +according to the following rule: + + * If the header file only describes the internal interface of a + module, then the file is placed in the same directory as the + source files. + * If the header file describes an interface used by other parts + of the kernel that are located in different directories, then + the file is placed in include/linux/. + + NOTE: + There are two notable exceptions to this rule: larger + subsystems have their own directory under include/, such as + include/scsi; and architecture specific headers are located + under arch/$(ARCH)/include/. + +4.1 Kernel Includes +------------------- + + To include a header file located under include/linux/, simply + use:: + + #include + + kbuild will add options to "gcc" so the relevant directories + are searched. + +4.2 Single Subdirectory +----------------------- + + External modules tend to place header files in a separate + include/ directory where their source is located, although this + is not the usual kernel style. To inform kbuild of the + directory, use either ccflags-y or CFLAGS_.o. + + Using the example from section 3, if we moved 8123_if.h to a + subdirectory named include, the resulting kbuild file would + look like:: + + --> filename: Kbuild + obj-m := 8123.o + + ccflags-y := -Iinclude + 8123-y := 8123_if.o 8123_pci.o 8123_bin.o + + Note that in the assignment there is no space between -I and + the path. This is a limitation of kbuild: there must be no + space present. + +4.3 Several Subdirectories +-------------------------- + + kbuild can handle files that are spread over several directories. + Consider the following example:: + + . + |__ src + | |__ complex_main.c + | |__ hal + | |__ hardwareif.c + | |__ include + | |__ hardwareif.h + |__ include + |__ complex.h + + To build the module complex.ko, we then need the following + kbuild file:: + + --> filename: Kbuild + obj-m := complex.o + complex-y := src/complex_main.o + complex-y += src/hal/hardwareif.o + + ccflags-y := -I$(src)/include + ccflags-y += -I$(src)/src/hal/include + + As you can see, kbuild knows how to handle object files located + in other directories. The trick is to specify the directory + relative to the kbuild file's location. That being said, this + is NOT recommended practice. + + For the header files, kbuild must be explicitly told where to + look. When kbuild executes, the current directory is always the + root of the kernel tree (the argument to "-C") and therefore an + absolute path is needed. $(src) provides the absolute path by + pointing to the directory where the currently executing kbuild + file is located. + + +5. Module Installation +====================== + +Modules which are included in the kernel are installed in the +directory: + + /lib/modules/$(KERNELRELEASE)/kernel/ + +And external modules are installed in: + + /lib/modules/$(KERNELRELEASE)/extra/ + +5.1 INSTALL_MOD_PATH +-------------------- + + Above are the default directories but as always some level of + customization is possible. A prefix can be added to the + installation path using the variable INSTALL_MOD_PATH:: + + $ make INSTALL_MOD_PATH=/frodo modules_install + => Install dir: /frodo/lib/modules/$(KERNELRELEASE)/kernel/ + + INSTALL_MOD_PATH may be set as an ordinary shell variable or, + as shown above, can be specified on the command line when + calling "make." This has effect when installing both in-tree + and out-of-tree modules. + +5.2 INSTALL_MOD_DIR +------------------- + + External modules are by default installed to a directory under + /lib/modules/$(KERNELRELEASE)/extra/, but you may wish to + locate modules for a specific functionality in a separate + directory. For this purpose, use INSTALL_MOD_DIR to specify an + alternative name to "extra.":: + + $ make INSTALL_MOD_DIR=gandalf -C $KDIR \ + M=$PWD modules_install + => Install dir: /lib/modules/$(KERNELRELEASE)/gandalf/ + + +6. Module Versioning +==================== + +Module versioning is enabled by the CONFIG_MODVERSIONS tag, and is used +as a simple ABI consistency check. A CRC value of the full prototype +for an exported symbol is created. When a module is loaded/used, the +CRC values contained in the kernel are compared with similar values in +the module; if they are not equal, the kernel refuses to load the +module. + +Module.symvers contains a list of all exported symbols from a kernel +build. + +6.1 Symbols From the Kernel (vmlinux + modules) +----------------------------------------------- + + During a kernel build, a file named Module.symvers will be + generated. Module.symvers contains all exported symbols from + the kernel and compiled modules. For each symbol, the + corresponding CRC value is also stored. + + The syntax of the Module.symvers file is:: + + + + 0x2d036834 scsi_remove_host drivers/scsi/scsi_mod + + For a kernel build without CONFIG_MODVERSIONS enabled, the CRC + would read 0x00000000. + + Module.symvers serves two purposes: + + 1) It lists all exported symbols from vmlinux and all modules. + 2) It lists the CRC if CONFIG_MODVERSIONS is enabled. + +6.2 Symbols and External Modules +-------------------------------- + + When building an external module, the build system needs access + to the symbols from the kernel to check if all external symbols + are defined. This is done in the MODPOST step. modpost obtains + the symbols by reading Module.symvers from the kernel source + tree. If a Module.symvers file is present in the directory + where the external module is being built, this file will be + read too. During the MODPOST step, a new Module.symvers file + will be written containing all exported symbols that were not + defined in the kernel. + +--- 6.3 Symbols From Another External Module + + Sometimes, an external module uses exported symbols from + another external module. kbuild needs to have full knowledge of + all symbols to avoid spitting out warnings about undefined + symbols. Three solutions exist for this situation. + + NOTE: The method with a top-level kbuild file is recommended + but may be impractical in certain situations. + + Use a top-level kbuild file + If you have two modules, foo.ko and bar.ko, where + foo.ko needs symbols from bar.ko, you can use a + common top-level kbuild file so both modules are + compiled in the same build. Consider the following + directory layout:: + + ./foo/ <= contains foo.ko + ./bar/ <= contains bar.ko + + The top-level kbuild file would then look like:: + + #./Kbuild (or ./Makefile): + obj-y := foo/ bar/ + + And executing:: + + $ make -C $KDIR M=$PWD + + will then do the expected and compile both modules with + full knowledge of symbols from either module. + + Use an extra Module.symvers file + When an external module is built, a Module.symvers file + is generated containing all exported symbols which are + not defined in the kernel. To get access to symbols + from bar.ko, copy the Module.symvers file from the + compilation of bar.ko to the directory where foo.ko is + built. During the module build, kbuild will read the + Module.symvers file in the directory of the external + module, and when the build is finished, a new + Module.symvers file is created containing the sum of + all symbols defined and not part of the kernel. + + Use "make" variable KBUILD_EXTRA_SYMBOLS + If it is impractical to copy Module.symvers from + another module, you can assign a space separated list + of files to KBUILD_EXTRA_SYMBOLS in your build file. + These files will be loaded by modpost during the + initialization of its symbol tables. + + +7. Tips & Tricks +================ + +7.1 Testing for CONFIG_FOO_BAR +------------------------------ + + Modules often need to check for certain `CONFIG_` options to + decide if a specific feature is included in the module. In + kbuild this is done by referencing the `CONFIG_` variable + directly:: + + #fs/ext2/Makefile + obj-$(CONFIG_EXT2_FS) += ext2.o + + ext2-y := balloc.o bitmap.o dir.o + ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o + + External modules have traditionally used "grep" to check for + specific `CONFIG_` settings directly in .config. This usage is + broken. As introduced before, external modules should use + kbuild for building and can therefore use the same methods as + in-tree modules when testing for `CONFIG_` definitions. diff --git a/Documentation/kbuild/modules.txt b/Documentation/kbuild/modules.txt deleted file mode 100644 index 80295c613e37..000000000000 --- a/Documentation/kbuild/modules.txt +++ /dev/null @@ -1,541 +0,0 @@ -Building External Modules - -This document describes how to build an out-of-tree kernel module. - -=== Table of Contents - - === 1 Introduction - === 2 How to Build External Modules - --- 2.1 Command Syntax - --- 2.2 Options - --- 2.3 Targets - --- 2.4 Building Separate Files - === 3.

This shortened filename can be used in - the assignment to the module. - - Throughout this section, 8123_bin.o_shipped has been used to - build the kernel module 8123.ko; it has been included as - 8123_bin.o. - - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - Although there is no distinction between the ordinary source - files and the binary file, kbuild will pick up different rules - when creating the object file for the module. - ---- 3.4 Building Multiple Modules - - kbuild supports building multiple modules with a single build - file. For example, if you wanted to build two modules, foo.ko - and bar.ko, the kbuild lines would be: - - obj-m := foo.o bar.o - foo-y := - bar-y := - - It is that simple! - - -=== 4. Include Files - -Within the kernel, header files are kept in standard locations -according to the following rule: - - * If the header file only describes the internal interface of a - module, then the file is placed in the same directory as the - source files. - * If the header file describes an interface used by other parts - of the kernel that are located in different directories, then - the file is placed in include/linux/. - - NOTE: There are two notable exceptions to this rule: larger - subsystems have their own directory under include/, such as - include/scsi; and architecture specific headers are located - under arch/$(ARCH)/include/. - ---- 4.1 Kernel Includes - - To include a header file located under include/linux/, simply - use: - - #include - - kbuild will add options to "gcc" so the relevant directories - are searched. - ---- 4.2 Single Subdirectory - - External modules tend to place header files in a separate - include/ directory where their source is located, although this - is not the usual kernel style. To inform kbuild of the - directory, use either ccflags-y or CFLAGS_.o. - - Using the example from section 3, if we moved 8123_if.h to a - subdirectory named include, the resulting kbuild file would - look like: - - --> filename: Kbuild - obj-m := 8123.o - - ccflags-y := -Iinclude - 8123-y := 8123_if.o 8123_pci.o 8123_bin.o - - Note that in the assignment there is no space between -I and - the path. This is a limitation of kbuild: there must be no - space present. - ---- 4.3 Several Subdirectories - - kbuild can handle files that are spread over several directories. - Consider the following example: - - . - |__ src - | |__ complex_main.c - | |__ hal - | |__ hardwareif.c - | |__ include - | |__ hardwareif.h - |__ include - |__ complex.h - - To build the module complex.ko, we then need the following - kbuild file: - - --> filename: Kbuild - obj-m := complex.o - complex-y := src/complex_main.o - complex-y += src/hal/hardwareif.o - - ccflags-y := -I$(src)/include - ccflags-y += -I$(src)/src/hal/include - - As you can see, kbuild knows how to handle object files located - in other directories. The trick is to specify the directory - relative to the kbuild file's location. That being said, this - is NOT recommended practice. - - For the header files, kbuild must be explicitly told where to - look. When kbuild executes, the current directory is always the - root of the kernel tree (the argument to "-C") and therefore an - absolute path is needed. $(src) provides the absolute path by - pointing to the directory where the currently executing kbuild - file is located. - - -=== 5. Module Installation - -Modules which are included in the kernel are installed in the -directory: - - /lib/modules/$(KERNELRELEASE)/kernel/ - -And external modules are installed in: - - /lib/modules/$(KERNELRELEASE)/extra/ - ---- 5.1 INSTALL_MOD_PATH - - Above are the default directories but as always some level of - customization is possible. A prefix can be added to the - installation path using the variable INSTALL_MOD_PATH: - - $ make INSTALL_MOD_PATH=/frodo modules_install - => Install dir: /frodo/lib/modules/$(KERNELRELEASE)/kernel/ - - INSTALL_MOD_PATH may be set as an ordinary shell variable or, - as shown above, can be specified on the command line when - calling "make." This has effect when installing both in-tree - and out-of-tree modules. - ---- 5.2 INSTALL_MOD_DIR - - External modules are by default installed to a directory under - /lib/modules/$(KERNELRELEASE)/extra/, but you may wish to - locate modules for a specific functionality in a separate - directory. For this purpose, use INSTALL_MOD_DIR to specify an - alternative name to "extra." - - $ make INSTALL_MOD_DIR=gandalf -C $KDIR \ - M=$PWD modules_install - => Install dir: /lib/modules/$(KERNELRELEASE)/gandalf/ - - -=== 6. Module Versioning - -Module versioning is enabled by the CONFIG_MODVERSIONS tag, and is used -as a simple ABI consistency check. A CRC value of the full prototype -for an exported symbol is created. When a module is loaded/used, the -CRC values contained in the kernel are compared with similar values in -the module; if they are not equal, the kernel refuses to load the -module. - -Module.symvers contains a list of all exported symbols from a kernel -build. - ---- 6.1 Symbols From the Kernel (vmlinux + modules) - - During a kernel build, a file named Module.symvers will be - generated. Module.symvers contains all exported symbols from - the kernel and compiled modules. For each symbol, the - corresponding CRC value is also stored. - - The syntax of the Module.symvers file is: - - - 0x2d036834 scsi_remove_host drivers/scsi/scsi_mod - - For a kernel build without CONFIG_MODVERSIONS enabled, the CRC - would read 0x00000000. - - Module.symvers serves two purposes: - 1) It lists all exported symbols from vmlinux and all modules. - 2) It lists the CRC if CONFIG_MODVERSIONS is enabled. - ---- 6.2 Symbols and External Modules - - When building an external module, the build system needs access - to the symbols from the kernel to check if all external symbols - are defined. This is done in the MODPOST step. modpost obtains - the symbols by reading Module.symvers from the kernel source - tree. If a Module.symvers file is present in the directory - where the external module is being built, this file will be - read too. During the MODPOST step, a new Module.symvers file - will be written containing all exported symbols that were not - defined in the kernel. - ---- 6.3 Symbols From Another External Module - - Sometimes, an external module uses exported symbols from - another external module. kbuild needs to have full knowledge of - all symbols to avoid spitting out warnings about undefined - symbols. Three solutions exist for this situation. - - NOTE: The method with a top-level kbuild file is recommended - but may be impractical in certain situations. - - Use a top-level kbuild file - If you have two modules, foo.ko and bar.ko, where - foo.ko needs symbols from bar.ko, you can use a - common top-level kbuild file so both modules are - compiled in the same build. Consider the following - directory layout: - - ./foo/ <= contains foo.ko - ./bar/ <= contains bar.ko - - The top-level kbuild file would then look like: - - #./Kbuild (or ./Makefile): - obj-y := foo/ bar/ - - And executing - - $ make -C $KDIR M=$PWD - - will then do the expected and compile both modules with - full knowledge of symbols from either module. - - Use an extra Module.symvers file - When an external module is built, a Module.symvers file - is generated containing all exported symbols which are - not defined in the kernel. To get access to symbols - from bar.ko, copy the Module.symvers file from the - compilation of bar.ko to the directory where foo.ko is - built. During the module build, kbuild will read the - Module.symvers file in the directory of the external - module, and when the build is finished, a new - Module.symvers file is created containing the sum of - all symbols defined and not part of the kernel. - - Use "make" variable KBUILD_EXTRA_SYMBOLS - If it is impractical to copy Module.symvers from - another module, you can assign a space separated list - of files to KBUILD_EXTRA_SYMBOLS in your build file. - These files will be loaded by modpost during the - initialization of its symbol tables. - - -=== 7. Tips & Tricks - ---- 7.1 Testing for CONFIG_FOO_BAR - - Modules often need to check for certain CONFIG_ options to - decide if a specific feature is included in the module. In - kbuild this is done by referencing the CONFIG_ variable - directly. - - #fs/ext2/Makefile - obj-$(CONFIG_EXT2_FS) += ext2.o - - ext2-y := balloc.o bitmap.o dir.o - ext2-$(CONFIG_EXT2_FS_XATTR) += xattr.o - - External modules have traditionally used "grep" to check for - specific CONFIG_ settings directly in .config. This usage is - broken. As introduced before, external modules should use - kbuild for building and can therefore use the same methods as - in-tree modules when testing for CONFIG_ definitions. - diff --git a/Documentation/kernel-hacking/hacking.rst b/Documentation/kernel-hacking/hacking.rst index d824e4feaff3..5891a701a159 100644 --- a/Documentation/kernel-hacking/hacking.rst +++ b/Documentation/kernel-hacking/hacking.rst @@ -718,7 +718,7 @@ make a neat patch, there's administrative work to be done: - Usually you want a configuration option for your kernel hack.

After all, the primary purpose of a scheduling-clock interrupt -is to force a busy CPU to shift its attention among multiple duties, -and an idle CPU has no duties to shift its attention among. - -The CONFIG_NO_HZ_IDLE=y Kconfig option causes the kernel to avoid sending -scheduling-clock interrupts to idle CPUs, which is critically important -both to battery-powered devices and to highly virtualized mainframes. -A battery-powered device running a CONFIG_HZ_PERIODIC=y kernel would -drain its battery very quickly, easily 2-3 times as fast as would the -same device running a CONFIG_NO_HZ_IDLE=y kernel.

This is important -for applications with aggressive real-time response constraints because -it allows them to improve their worst-case response times by the maximum -duration of a scheduling-clock interrupt. It is also important for -computationally intensive short-iteration workloads: If any CPU is -delayed during a given iteration, all the other CPUs will be forced to -wait idle while the delayed CPU finishes. Thus, the delay is multiplied -by one less than the number of CPUs. In these situations, there is -again strong motivation to avoid sending scheduling-clock interrupts. - -By default, no CPU will be an adaptive-ticks CPU. The "nohz_full=" -boot parameter specifies the adaptive-ticks CPUs. For example, -"nohz_full=1,6-8" says that CPUs 1, 6, 7, and 8 are to be adaptive-ticks -CPUs. Note that you are prohibited from marking all of the CPUs as -adaptive-tick CPUs: At least one non-adaptive-tick CPU must remain -online to handle timekeeping tasks in order to ensure that system -calls like gettimeofday() returns accurate values on adaptive-tick CPUs. -(This is not an issue for CONFIG_NO_HZ_IDLE=y because there are no running -user processes to observe slight drifts in clock rate.) Therefore, the -boot CPU is prohibited from entering adaptive-ticks mode. Specifying a -"nohz_full=" mask that includes the boot CPU will result in a boot-time -error message, and the boot CPU will be removed from the mask. Note that -this means that your system must have at least two CPUs in order for -CONFIG_NO_HZ_FULL=y to do anything for you. - -Finally, adaptive-ticks CPUs must have their RCU callbacks offloaded. -This is covered in the "RCU IMPLICATIONS" section below. - -Normally, a CPU remains in adaptive-ticks mode as long as possible. -In particular, transitioning to kernel mode does not automatically change -the mode. Instead, the CPU will exit adaptive-ticks mode only if needed, -for example, if that CPU enqueues an RCU callback. - -Just as with dyntick-idle mode, the benefits of adaptive-tick mode do -not come for free: - -1. CONFIG_NO_HZ_FULL selects CONFIG_NO_HZ_COMMON, so you cannot run - adaptive ticks without also running dyntick idle. This dependency - extends down into the implementation, so that all of the costs - of CONFIG_NO_HZ_IDLE are also incurred by CONFIG_NO_HZ_FULL. - -2. The user/kernel transitions are slightly more expensive due - to the need to inform kernel subsystems (such as RCU) about - the change in mode. - -3. POSIX CPU timers prevent CPUs from entering adaptive-tick mode. - Real-time applications needing to take actions based on CPU time - consumption need to use other means of doing so. - -4. If there are more perf events pending than the hardware can - accommodate, they are normally round-robined so as to collect - all of them over time. Adaptive-tick mode may prevent this - round-robining from happening. This will likely be fixed by - preventing CPUs with large numbers of perf events pending from - entering adaptive-tick mode. - -5. Scheduler statistics for adaptive-tick CPUs may be computed - slightly differently than those for non-adaptive-tick CPUs. - This might in turn perturb load-balancing of real-time tasks. - -6. The LB_BIAS scheduler feature is disabled by adaptive ticks. - -Although improvements are expected over time, adaptive ticks is quite -useful for many types of real-time and compute-intensive applications. -However, the drawbacks listed above mean that adaptive ticks should not -(yet) be enabled by default. - - -RCU IMPLICATIONS - -There are situations in which idle CPUs cannot be permitted to -enter either dyntick-idle mode or adaptive-tick mode, the most -common being when that CPU has RCU callbacks pending. - -The CONFIG_RCU_FAST_NO_HZ=y Kconfig option may be used to cause such CPUs -to enter dyntick-idle mode or adaptive-tick mode anyway. In this case, -a timer will awaken these CPUs every four jiffies in order to ensure -that the RCU callbacks are processed in a timely fashion. - -Another approach is to offload RCU callback processing to "rcuo" kthreads -using the CONFIG_RCU_NOCB_CPU=y Kconfig option. The specific CPUs to -offload may be selected using The "rcu_nocbs=" kernel boot parameter, -which takes a comma-separated list of CPUs and CPU ranges, for example, -"1,3-5" selects CPUs 1, 3, 4, and 5. - -The offloaded CPUs will never queue RCU callbacks, and therefore RCU -never prevents offloaded CPUs from entering either dyntick-idle mode -or adaptive-tick mode. That said, note that it is up to userspace to -pin the "rcuo" kthreads to specific CPUs if desired. Otherwise, the -scheduler will decide where to run them, which might or might not be -where you want them to run. - - -TESTING - -So you enable all the OS-jitter features described in this document, -but do not see any change in your workload's behavior. Is this because -your workload isn't affected that much by OS jitter, or is it because -something else is in the way? This section helps answer this question -by providing a simple OS-jitter test suite, which is available on branch -master of the following git archive: - -git://git.kernel.org/pub/scm/linux/kernel/git/frederic/dynticks-testing.git - -Clone this archive and follow the instructions in the README file. -This test procedure will produce a trace that will allow you to evaluate -whether or not you have succeeded in removing OS jitter from your system. -If this trace shows that you have removed OS jitter as much as is -possible, then you can conclude that your workload is not all that -sensitive to OS jitter. - -Note: this test requires that your system have at least two CPUs. -We do not currently have a good way to remove OS jitter from single-CPU -systems. - - -KNOWN ISSUES - -o Dyntick-idle slows transitions to and from idle slightly. - In practice, this has not been a problem except for the most - aggressive real-time workloads, which have the option of disabling - dyntick-idle mode, an option that most of them take. However, - some workloads will no doubt want to use adaptive ticks to - eliminate scheduling-clock interrupt latencies. Here are some - options for these workloads: - - a. Use PMQOS from userspace to inform the kernel of your - latency requirements (preferred). - - b. On x86 systems, use the "idle=mwait" boot parameter. - - c. On x86 systems, use the "intel_idle.max_cstate=" to limit - ` the maximum C-state depth. - - d. On x86 systems, use the "idle=poll" boot parameter. - However, please note that use of this parameter can cause - your CPU to overheat, which may cause thermal throttling - to degrade your latencies -- and that this degradation can - be even worse than that of dyntick-idle. Furthermore, - this parameter effectively disables Turbo Mode on Intel - CPUs, which can significantly reduce maximum performance. - -o Adaptive-ticks slows user/kernel transitions slightly. - This is not expected to be a problem for computationally intensive - workloads, which have few such transitions. Careful benchmarking - will be required to determine whether or not other workloads - are significantly affected by this effect. - -o Adaptive-ticks does not do anything unless there is only one - runnable task for a given CPU, even though there are a number - of other situations where the scheduling-clock tick is not - needed. To give but one example, consider a CPU that has one - runnable high-priority SCHED_FIFO task and an arbitrary number - of low-priority SCHED_OTHER tasks. In this case, the CPU is - required to run the SCHED_FIFO task until it either blocks or - some other higher-priority task awakens on (or is assigned to) - this CPU, so there is no point in sending a scheduling-clock - interrupt to this CPU. However, the current implementation - nevertheless sends scheduling-clock interrupts to CPUs having a - single runnable SCHED_FIFO task and multiple runnable SCHED_OTHER - tasks, even though these interrupts are unnecessary. - - And even when there are multiple runnable tasks on a given CPU, - there is little point in interrupting that CPU until the current - running task's timeslice expires, which is almost always way - longer than the time of the next scheduling-clock interrupt. - - Better handling of these sorts of situations is future work. - -o A reboot is required to reconfigure both adaptive idle and RCU - callback offloading. Runtime reconfiguration could be provided - if needed, however, due to the complexity of reconfiguring RCU at - runtime, there would need to be an earthshakingly good reason. - Especially given that you have the straightforward option of - simply offloading RCU callbacks from all CPUs and pinning them - where you want them whenever you want them pinned. - -o Additional configuration is required to deal with other sources - of OS jitter, including interrupts and system-utility tasks - and processes. This configuration normally involves binding - interrupts and tasks to particular CPUs. - -o Some sources of OS jitter can currently be eliminated only by - constraining the workload. For example, the only way to eliminate - OS jitter due to global TLB shootdowns is to avoid the unmapping - operations (such as kernel module unload operations) that - result in these shootdowns. For another example, page faults - and TLB misses can be reduced (and in some cases eliminated) by - using huge pages and by constraining the amount of memory used - by the application. Pre-faulting the working set can also be - helpful, especially when combined with the mlock() and mlockall() - system calls. - -o Unless all CPUs are idle, at least one CPU must keep the - scheduling-clock interrupt going in order to support accurate - timekeeping. - -o If there might potentially be some adaptive-ticks CPUs, there - will be at least one CPU keeping the scheduling-clock interrupt - going, even if all CPUs are otherwise idle. - - Better handling of this situation is ongoing work. - -o Some process-handling operations still require the occasional - scheduling-clock tick. These operations include calculating CPU - load, maintaining sched average, computing CFS entity vruntime, - computing avenrun, and carrying out load balancing.

The next event is currently defined to be periodic, with its +period defined at compile time. The setup and selection of the event device +for various event driven functionalities is hardwired into the architecture +dependent code. This results in duplicated code across all architectures and +makes it extremely difficult to change the configuration of the system to use +event interrupt devices other than those already built into the +architecture. Another implication of the current design is that it is necessary +to touch all the architecture-specific implementations in order to provide new +functionality like high resolution timers or dynamic ticks. + +The clock events subsystem tries to address this problem by providing a generic +solution to manage clock event devices and their usage for the various clock +event driven kernel functionalities. The goal of the clock event subsystem is +to minimize the clock event related architecture dependent code to the pure +hardware related handling and to allow easy addition and utilization of new +clock event devices. It also minimizes the duplicated code across the +architectures as it provides generic functionality down to the interrupt +service handler, which is almost inherently hardware dependent. + +Clock event devices are registered either by the architecture dependent boot +code or at module insertion time. Each clock event device fills a data +structure with clock-specific property parameters and callback functions. The +clock event management decides, by using the specified property parameters, the +set of system functions a clock event device will be used to support. This +includes the distinction of per-CPU and per-system global event devices. + +System-level global event devices are used for the Linux periodic tick. Per-CPU +event devices are used to provide local CPU functionality such as process +accounting, profiling, and high resolution timers. + +The management layer assigns one or more of the following functions to a clock +event device: + + - system global periodic tick (jiffies update) + - cpu local update_process_times + - cpu local profiling + - cpu local next event interrupt (non periodic mode) + +The clock event device delegates the selection of those timer interrupt related +functions completely to the management layer. The clock management layer stores +a function pointer in the device description structure, which has to be called +from the hardware level handler. This removes a lot of duplicated code from the +architecture specific timer interrupt handlers and hands the control over the +clock event devices and the assignment of timer interrupt related functionality +to the core code. + +The clock event layer API is rather small. Aside from the clock event device +registration interface it provides functions to schedule the next event +interrupt, clock event device notification service and support for suspend and +resume. + +The framework adds about 700 lines of code which results in a 2KB increase of +the kernel binary size. The conversion of i386 removes about 100 lines of +code. The binary size decrease is in the range of 400 byte. We believe that the +increase of flexibility and the avoidance of duplicated code across +architectures justifies the slight increase of the binary size. + +The conversion of an architecture has no functional impact, but allows to +utilize the high resolution and dynamic tick functionalities without any change +to the clock event device and timer interrupt code. After the conversion the +enabling of high resolution timers and dynamic ticks is simply provided by +adding the kernel/time/Kconfig file to the architecture specific Kconfig and +adding the dynamic tick specific calls to the idle routine (a total of 3 lines +added to the idle function and the Kconfig file) + +Figure #4 (OLS slides p.20) illustrates the transformation. + + +high resolution timer functionality +----------------------------------- + +During system boot it is not possible to use the high resolution timer +functionality, while making it possible would be difficult and would serve no +useful function. The initialization of the clock event device framework, the +clock source framework (GTOD) and hrtimers itself has to be done and +appropriate clock sources and clock event devices have to be registered before +the high resolution functionality can work. Up to the point where hrtimers are +initialized, the system works in the usual low resolution periodic mode. The +clock source and the clock event device layers provide notification functions +which inform hrtimers about availability of new hardware. hrtimers validates +the usability of the registered clock sources and clock event devices before +switching to high resolution mode. This ensures also that a kernel which is +configured for high resolution timers can run on a system which lacks the +necessary hardware support. + +The high resolution timer code does not support SMP machines which have only +global clock event devices. The support of such hardware would involve IPI +calls when an interrupt happens. The overhead would be much larger than the +benefit. This is the reason why we currently disable high resolution and +dynamic ticks on i386 SMP systems which stop the local APIC in C3 power +state. A workaround is available as an idea, but the problem has not been +tackled yet. + +The time ordered insertion of timers provides all the infrastructure to decide +whether the event device has to be reprogrammed when a timer is added. The +decision is made per timer base and synchronized across per-cpu timer bases in +a support function. The design allows the system to utilize separate per-CPU +clock event devices for the per-CPU timer bases, but currently only one +reprogrammable clock event device per-CPU is utilized. + +When the timer interrupt happens, the next event interrupt handler is called +from the clock event distribution code and moves expired timers from the +red-black tree to a separate double linked list and invokes the softirq +handler. An additional mode field in the hrtimer structure allows the system to +execute callback functions directly from the next event interrupt handler. This +is restricted to code which can safely be executed in the hard interrupt +context. This applies, for example, to the common case of a wakeup function as +used by nanosleep. The advantage of executing the handler in the interrupt +context is the avoidance of up to two context switches - from the interrupted +context to the softirq and to the task which is woken up by the expired +timer. + +Once a system has switched to high resolution mode, the periodic tick is +switched off. This disables the per system global periodic clock event device - +e.g. the PIT on i386 SMP systems. + +The periodic tick functionality is provided by an per-cpu hrtimer. The callback +function is executed in the next event interrupt context and updates jiffies +and calls update_process_times and profiling. The implementation of the hrtimer +based periodic tick is designed to be extended with dynamic tick functionality. +This allows to use a single clock event device to schedule high resolution +timer and periodic events (jiffies tick, profiling, process accounting) on UP +systems. This has been proved to work with the PIT on i386 and the Incrementer +on PPC. + +The softirq for running the hrtimer queues and executing the callbacks has been +separated from the tick bound timer softirq to allow accurate delivery of high +resolution timer signals which are used by itimer and POSIX interval +timers. The execution of this softirq can still be delayed by other softirqs, +but the overall latencies have been significantly improved by this separation. + +Figure #5 (OLS slides p.22) illustrates the transformation. + + +dynamic ticks +------------- + +Dynamic ticks are the logical consequence of the hrtimer based periodic tick +replacement (sched_tick).

The function is also +called when an interrupt happens during the idle period, which does not cause a +reschedule. The call is necessary as the interrupt handler might have armed a +new timer whose expiry time is before the time which was identified as the +nearest event in the previous call to hrtimer_stop_sched_tick. + +hrtimer_restart_sched_tick() is called when the CPU leaves the idle state before +it calls schedule(). hrtimer_restart_sched_tick() resumes the periodic tick, +which is kept active until the next call to hrtimer_stop_sched_tick(). + +hrtimer_update_jiffies() is called from irq_enter() when an interrupt happens +in the idle period to make sure that jiffies are up to date and the interrupt +handler has not to deal with an eventually stale jiffy value. + +The dynamic tick feature provides statistical values which are exported to +userspace via /proc/stat and can be made available for enhanced power +management control. + +The implementation leaves room for further development like full tickless +systems, where the time slice is controlled by the scheduler, variable +frequency profiling, and a complete removal of jiffies in the future. + + +Aside the current initial submission of i386 support, the patchset has been +extended to x86_64 and ARM already.

After a lot of +back and forth trying to integrate high-resolution and high-precision +features into the existing timer framework, and after testing various +such high-resolution timer implementations in practice, we came to the +conclusion that the timer wheel code is fundamentally not suitable for +such an approach. We initially didn't believe this ('there must be a way +to solve this'), and spent a considerable effort trying to integrate +things into the timer wheel, but we failed. In hindsight, there are +several reasons why such integration is hard/impossible: + +- the forced handling of low-resolution and high-resolution timers in + the same way leads to a lot of compromises, macro magic and #ifdef + mess. The timers.c code is very "tightly coded" around jiffies and + 32-bitness assumptions, and has been honed and micro-optimized for a + relatively narrow use case (jiffies in a relatively narrow HZ range) + for many years - and thus even small extensions to it easily break + the wheel concept, leading to even worse compromises. The timer wheel + code is very good and tight code, there's zero problems with it in its + current usage - but it is simply not suitable to be extended for + high-res timers. + +- the unpredictable [O(N)] overhead of cascading leads to delays which + necessitate a more complex handling of high resolution timers, which + in turn decreases robustness. Such a design still leads to rather large + timing inaccuracies. Cascading is a fundamental property of the timer + wheel concept, it cannot be 'designed out' without inevitably + degrading other portions of the timers.c code in an unacceptable way. + +- the implementation of the current posix-timer subsystem on top of + the timer wheel has already introduced a quite complex handling of + the required readjusting of absolute CLOCK_REALTIME timers at + settimeofday or NTP time - further underlying our experience by + example: that the timer wheel data structure is too rigid for high-res + timers. + +- the timer wheel code is most optimal for use cases which can be + identified as "timeouts". Such timeouts are usually set up to cover + error conditions in various I/O paths, such as networking and block + I/O. The vast majority of those timers never expire and are rarely + recascaded because the expected correct event arrives in time so they + can be removed from the timer wheel before any further processing of + them becomes necessary. Thus the users of these timeouts can accept + the granularity and precision tradeoffs of the timer wheel, and + largely expect the timer subsystem to have near-zero overhead. + Accurate timing for them is not a core purpose - in fact most of the + timeout values used are ad-hoc. For them it is at most a necessary + evil to guarantee the processing of actual timeout completions + (because most of the timeouts are deleted before completion), which + should thus be as cheap and unintrusive as possible. + +The primary users of precision timers are user-space applications that +utilize nanosleep, posix-timers and itimer interfaces. Also, in-kernel +users like drivers and subsystems which require precise timed events +(e.g. multimedia) can benefit from the availability of a separate +high-resolution timer subsystem as well. + +While this subsystem does not offer high-resolution clock sources just +yet, the hrtimer subsystem can be easily extended with high-resolution +clock capabilities, and patches for that exist and are maturing quickly. +The increasing demand for realtime and multimedia applications along +with other potential users for precise timers gives another reason to +separate the "timeout" and "precise timer" subsystems. + +Another potential benefit is that such a separation allows even more +special-purpose optimization of the existing timer wheel for the low +resolution and low precision use cases - once the precision-sensitive +APIs are separated from the timer wheel and are migrated over to +hrtimers. E.g. we could decrease the frequency of the timeout subsystem +from 250 Hz to 100 HZ (or even smaller). + +hrtimer subsystem implementation details +---------------------------------------- + +the basic design considerations were: + +- simplicity + +- data structure not bound to jiffies or any other granularity. All the + kernel logic works at 64-bit nanoseconds resolution - no compromises. + +- simplification of existing, timing related kernel code + +another basic requirement was the immediate enqueueing and ordering of +timers at activation time. After looking at several possible solutions +such as radix trees and hashes, we chose the red black tree as the basic +data structure. Rbtrees are available as a library in the kernel and are +used in various performance-critical areas of e.g. memory management and +file systems. The rbtree is solely used for time sorted ordering, while +a separate list is used to give the expiry code fast access to the +queued timers, without having to walk the rbtree. + +(This separate list is also useful for later when we'll introduce +high-resolution clocks, where we need separate pending and expired +queues while keeping the time-order intact.) + +Time-ordered enqueueing is not purely for the purposes of +high-resolution clocks though, it also simplifies the handling of +absolute timers based on a low-resolution CLOCK_REALTIME.

After a lot of -back and forth trying to integrate high-resolution and high-precision -features into the existing timer framework, and after testing various -such high-resolution timer implementations in practice, we came to the -conclusion that the timer wheel code is fundamentally not suitable for -such an approach. We initially didn't believe this ('there must be a way -to solve this'), and spent a considerable effort trying to integrate -things into the timer wheel, but we failed. In hindsight, there are -several reasons why such integration is hard/impossible: - -- the forced handling of low-resolution and high-resolution timers in - the same way leads to a lot of compromises, macro magic and #ifdef - mess. The timers.c code is very "tightly coded" around jiffies and - 32-bitness assumptions, and has been honed and micro-optimized for a - relatively narrow use case (jiffies in a relatively narrow HZ range) - for many years - and thus even small extensions to it easily break - the wheel concept, leading to even worse compromises. The timer wheel - code is very good and tight code, there's zero problems with it in its - current usage - but it is simply not suitable to be extended for - high-res timers. - -- the unpredictable [O(N)] overhead of cascading leads to delays which - necessitate a more complex handling of high resolution timers, which - in turn decreases robustness. Such a design still leads to rather large - timing inaccuracies. Cascading is a fundamental property of the timer - wheel concept, it cannot be 'designed out' without inevitably - degrading other portions of the timers.c code in an unacceptable way. - -- the implementation of the current posix-timer subsystem on top of - the timer wheel has already introduced a quite complex handling of - the required readjusting of absolute CLOCK_REALTIME timers at - settimeofday or NTP time - further underlying our experience by - example: that the timer wheel data structure is too rigid for high-res - timers. - -- the timer wheel code is most optimal for use cases which can be - identified as "timeouts". Such timeouts are usually set up to cover - error conditions in various I/O paths, such as networking and block - I/O. The vast majority of those timers never expire and are rarely - recascaded because the expected correct event arrives in time so they - can be removed from the timer wheel before any further processing of - them becomes necessary. Thus the users of these timeouts can accept - the granularity and precision tradeoffs of the timer wheel, and - largely expect the timer subsystem to have near-zero overhead. - Accurate timing for them is not a core purpose - in fact most of the - timeout values used are ad-hoc. For them it is at most a necessary - evil to guarantee the processing of actual timeout completions - (because most of the timeouts are deleted before completion), which - should thus be as cheap and unintrusive as possible. - -The primary users of precision timers are user-space applications that -utilize nanosleep, posix-timers and itimer interfaces. Also, in-kernel -users like drivers and subsystems which require precise timed events -(e.g. multimedia) can benefit from the availability of a separate -high-resolution timer subsystem as well. - -While this subsystem does not offer high-resolution clock sources just -yet, the hrtimer subsystem can be easily extended with high-resolution -clock capabilities, and patches for that exist and are maturing quickly. -The increasing demand for realtime and multimedia applications along -with other potential users for precise timers gives another reason to -separate the "timeout" and "precise timer" subsystems. - -Another potential benefit is that such a separation allows even more -special-purpose optimization of the existing timer wheel for the low -resolution and low precision use cases - once the precision-sensitive -APIs are separated from the timer wheel and are migrated over to -hrtimers.

Reducing OS jitter is important for +some types of computationally intensive high-performance computing (HPC) +applications and for real-time applications. + +There are three main ways of managing scheduling-clock interrupts +(also known as "scheduling-clock ticks" or simply "ticks"): + +1. Never omit scheduling-clock ticks (CONFIG_HZ_PERIODIC=y or + CONFIG_NO_HZ=n for older kernels). You normally will -not- + want to choose this option. + +2. Omit scheduling-clock ticks on idle CPUs (CONFIG_NO_HZ_IDLE=y or + CONFIG_NO_HZ=y for older kernels). This is the most common + approach, and should be the default. + +3. Omit scheduling-clock ticks on CPUs that are either idle or that + have only one runnable task (CONFIG_NO_HZ_FULL=y). Unless you + are running realtime applications or certain types of HPC + workloads, you will normally -not- want this option. + +These three cases are described in the following three sections, followed +by a third section on RCU-specific considerations, a fourth section +discussing testing, and a fifth and final section listing known issues. + + +Never Omit Scheduling-Clock Ticks +================================= + +Very old versions of Linux from the 1990s and the very early 2000s +are incapable of omitting scheduling-clock ticks. It turns out that +there are some situations where this old-school approach is still the +right approach, for example, in heavy workloads with lots of tasks +that use short bursts of CPU, where there are very frequent idle +periods, but where these idle periods are also quite short (tens or +hundreds of microseconds). For these types of workloads, scheduling +clock interrupts will normally be delivered any way because there +will frequently be multiple runnable tasks per CPU. In these cases, +attempting to turn off the scheduling clock interrupt will have no effect +other than increasing the overhead of switching to and from idle and +transitioning between user and kernel execution. + +This mode of operation can be selected using CONFIG_HZ_PERIODIC=y (or +CONFIG_NO_HZ=n for older kernels). + +However, if you are instead running a light workload with long idle +periods, failing to omit scheduling-clock interrupts will result in +excessive power consumption. This is especially bad on battery-powered +devices, where it results in extremely short battery lifetimes. If you +are running light workloads, you should therefore read the following +section. + +In addition, if you are running either a real-time workload or an HPC +workload with short iterations, the scheduling-clock interrupts can +degrade your applications performance. If this describes your workload, +you should read the following two sections. + + +Omit Scheduling-Clock Ticks For Idle CPUs +========================================= + +If a CPU is idle, there is little point in sending it a scheduling-clock +interrupt. After all, the primary purpose of a scheduling-clock interrupt +is to force a busy CPU to shift its attention among multiple duties, +and an idle CPU has no duties to shift its attention among. + +The CONFIG_NO_HZ_IDLE=y Kconfig option causes the kernel to avoid sending +scheduling-clock interrupts to idle CPUs, which is critically important +both to battery-powered devices and to highly virtualized mainframes. +A battery-powered device running a CONFIG_HZ_PERIODIC=y kernel would +drain its battery very quickly, easily 2-3 times as fast as would the +same device running a CONFIG_NO_HZ_IDLE=y kernel. A mainframe running +1,500 OS instances might find that half of its CPU time was consumed by +unnecessary scheduling-clock interrupts. In these situations, there +is strong motivation to avoid sending scheduling-clock interrupts to +idle CPUs. That said, dyntick-idle mode is not free: + +1. It increases the number of instructions executed on the path + to and from the idle loop. + +2. On many architectures, dyntick-idle mode also increases the + number of expensive clock-reprogramming operations. + +Therefore, systems with aggressive real-time response constraints often +run CONFIG_HZ_PERIODIC=y kernels (or CONFIG_NO_HZ=n for older kernels) +in order to avoid degrading from-idle transition latencies. + +An idle CPU that is not receiving scheduling-clock interrupts is said to +be "dyntick-idle", "in dyntick-idle mode", "in nohz mode", or "running +tickless". The remainder of this document will use "dyntick-idle mode". + +There is also a boot parameter "nohz=" that can be used to disable +dyntick-idle mode in CONFIG_NO_HZ_IDLE=y kernels by specifying "nohz=off". +By default, CONFIG_NO_HZ_IDLE=y kernels boot with "nohz=on", enabling +dyntick-idle mode. + + +Omit Scheduling-Clock Ticks For CPUs With Only One Runnable Task +================================================================ + +If a CPU has only one runnable task, there is little point in sending it +a scheduling-clock interrupt because there is no other task to switch to. +Note that omitting scheduling-clock ticks for CPUs with only one runnable +task implies also omitting them for idle CPUs. + +The CONFIG_NO_HZ_FULL=y Kconfig option causes the kernel to avoid +sending scheduling-clock interrupts to CPUs with a single runnable task, +and such CPUs are said to be "adaptive-ticks CPUs". This is important +for applications with aggressive real-time response constraints because +it allows them to improve their worst-case response times by the maximum +duration of a scheduling-clock interrupt. It is also important for +computationally intensive short-iteration workloads: If any CPU is +delayed during a given iteration, all the other CPUs will be forced to +wait idle while the delayed CPU finishes. Thus, the delay is multiplied +by one less than the number of CPUs. In these situations, there is +again strong motivation to avoid sending scheduling-clock interrupts. + +By default, no CPU will be an adaptive-ticks CPU. The "nohz_full=" +boot parameter specifies the adaptive-ticks CPUs. For example, +"nohz_full=1,6-8" says that CPUs 1, 6, 7, and 8 are to be adaptive-ticks +CPUs. Note that you are prohibited from marking all of the CPUs as +adaptive-tick CPUs: At least one non-adaptive-tick CPU must remain +online to handle timekeeping tasks in order to ensure that system +calls like gettimeofday() returns accurate values on adaptive-tick CPUs. +(This is not an issue for CONFIG_NO_HZ_IDLE=y because there are no running +user processes to observe slight drifts in clock rate.) Therefore, the +boot CPU is prohibited from entering adaptive-ticks mode. Specifying a +"nohz_full=" mask that includes the boot CPU will result in a boot-time +error message, and the boot CPU will be removed from the mask. Note that +this means that your system must have at least two CPUs in order for +CONFIG_NO_HZ_FULL=y to do anything for you. + +Finally, adaptive-ticks CPUs must have their RCU callbacks offloaded. +This is covered in the "RCU IMPLICATIONS" section below. + +Normally, a CPU remains in adaptive-ticks mode as long as possible. +In particular, transitioning to kernel mode does not automatically change +the mode. Instead, the CPU will exit adaptive-ticks mode only if needed, +for example, if that CPU enqueues an RCU callback. + +Just as with dyntick-idle mode, the benefits of adaptive-tick mode do +not come for free: + +1. CONFIG_NO_HZ_FULL selects CONFIG_NO_HZ_COMMON, so you cannot run + adaptive ticks without also running dyntick idle. This dependency + extends down into the implementation, so that all of the costs + of CONFIG_NO_HZ_IDLE are also incurred by CONFIG_NO_HZ_FULL. + +2. The user/kernel transitions are slightly more expensive due + to the need to inform kernel subsystems (such as RCU) about + the change in mode. + +3. POSIX CPU timers prevent CPUs from entering adaptive-tick mode. + Real-time applications needing to take actions based on CPU time + consumption need to use other means of doing so. + +4. If there are more perf events pending than the hardware can + accommodate, they are normally round-robined so as to collect + all of them over time. Adaptive-tick mode may prevent this + round-robining from happening. This will likely be fixed by + preventing CPUs with large numbers of perf events pending from + entering adaptive-tick mode. + +5. Scheduler statistics for adaptive-tick CPUs may be computed + slightly differently than those for non-adaptive-tick CPUs. + This might in turn perturb load-balancing of real-time tasks. + +6. The LB_BIAS scheduler feature is disabled by adaptive ticks. + +Although improvements are expected over time, adaptive ticks is quite +useful for many types of real-time and compute-intensive applications. +However, the drawbacks listed above mean that adaptive ticks should not +(yet) be enabled by default. + + +RCU Implications +================ + +There are situations in which idle CPUs cannot be permitted to +enter either dyntick-idle mode or adaptive-tick mode, the most +common being when that CPU has RCU callbacks pending. + +The CONFIG_RCU_FAST_NO_HZ=y Kconfig option may be used to cause such CPUs +to enter dyntick-idle mode or adaptive-tick mode anyway. In this case, +a timer will awaken these CPUs every four jiffies in order to ensure +that the RCU callbacks are processed in a timely fashion. + +Another approach is to offload RCU callback processing to "rcuo" kthreads +using the CONFIG_RCU_NOCB_CPU=y Kconfig option. The specific CPUs to +offload may be selected using The "rcu_nocbs=" kernel boot parameter, +which takes a comma-separated list of CPUs and CPU ranges, for example, +"1,3-5" selects CPUs 1, 3, 4, and 5. + +The offloaded CPUs will never queue RCU callbacks, and therefore RCU +never prevents offloaded CPUs from entering either dyntick-idle mode +or adaptive-tick mode. That said, note that it is up to userspace to +pin the "rcuo" kthreads to specific CPUs if desired. Otherwise, the +scheduler will decide where to run them, which might or might not be +where you want them to run. + + +Testing +======= + +So you enable all the OS-jitter features described in this document, +but do not see any change in your workload's behavior. Is this because +your workload isn't affected that much by OS jitter, or is it because +something else is in the way? This section helps answer this question +by providing a simple OS-jitter test suite, which is available on branch +master of the following git archive: + +git://git.kernel.org/pub/scm/linux/kernel/git/frederic/dynticks-testing.git + +Clone this archive and follow the instructions in the README file. +This test procedure will produce a trace that will allow you to evaluate +whether or not you have succeeded in removing OS jitter from your system. +If this trace shows that you have removed OS jitter as much as is +possible, then you can conclude that your workload is not all that +sensitive to OS jitter. + +Note: this test requires that your system have at least two CPUs. +We do not currently have a good way to remove OS jitter from single-CPU +systems. + + +Known Issues +============ + +* Dyntick-idle slows transitions to and from idle slightly. + In practice, this has not been a problem except for the most + aggressive real-time workloads, which have the option of disabling + dyntick-idle mode, an option that most of them take. However, + some workloads will no doubt want to use adaptive ticks to + eliminate scheduling-clock interrupt latencies. Here are some + options for these workloads: + + a. Use PMQOS from userspace to inform the kernel of your + latency requirements (preferred). + + b. On x86 systems, use the "idle=mwait" boot parameter. + + c. On x86 systems, use the "intel_idle.max_cstate=" to limit + ` the maximum C-state depth. + + d. On x86 systems, use the "idle=poll" boot parameter. + However, please note that use of this parameter can cause + your CPU to overheat, which may cause thermal throttling + to degrade your latencies -- and that this degradation can + be even worse than that of dyntick-idle. Furthermore, + this parameter effectively disables Turbo Mode on Intel + CPUs, which can significantly reduce maximum performance. + +* Adaptive-ticks slows user/kernel transitions slightly. + This is not expected to be a problem for computationally intensive + workloads, which have few such transitions. Careful benchmarking + will be required to determine whether or not other workloads + are significantly affected by this effect. + +* Adaptive-ticks does not do anything unless there is only one + runnable task for a given CPU, even though there are a number + of other situations where the scheduling-clock tick is not + needed. To give but one example, consider a CPU that has one + runnable high-priority SCHED_FIFO task and an arbitrary number + of low-priority SCHED_OTHER tasks. In this case, the CPU is + required to run the SCHED_FIFO task until it either blocks or + some other higher-priority task awakens on (or is assigned to) + this CPU, so there is no point in sending a scheduling-clock + interrupt to this CPU. However, the current implementation + nevertheless sends scheduling-clock interrupts to CPUs having a + single runnable SCHED_FIFO task and multiple runnable SCHED_OTHER + tasks, even though these interrupts are unnecessary. + + And even when there are multiple runnable tasks on a given CPU, + there is little point in interrupting that CPU until the current + running task's timeslice expires, which is almost always way + longer than the time of the next scheduling-clock interrupt. + + Better handling of these sorts of situations is future work. + +* A reboot is required to reconfigure both adaptive idle and RCU + callback offloading. Runtime reconfiguration could be provided + if needed, however, due to the complexity of reconfiguring RCU at + runtime, there would need to be an earthshakingly good reason. + Especially given that you have the straightforward option of + simply offloading RCU callbacks from all CPUs and pinning them + where you want them whenever you want them pinned. + +* Additional configuration is required to deal with other sources + of OS jitter, including interrupts and system-utility tasks + and processes. This configuration normally involves binding + interrupts and tasks to particular CPUs. + +* Some sources of OS jitter can currently be eliminated only by + constraining the workload. For example, the only way to eliminate + OS jitter due to global TLB shootdowns is to avoid the unmapping + operations (such as kernel module unload operations) that + result in these shootdowns. For another example, page faults + and TLB misses can be reduced (and in some cases eliminated) by + using huge pages and by constraining the amount of memory used + by the application. Pre-faulting the working set can also be + helpful, especially when combined with the mlock() and mlockall() + system calls. + +* Unless all CPUs are idle, at least one CPU must keep the + scheduling-clock interrupt going in order to support accurate + timekeeping. + +* If there might potentially be some adaptive-ticks CPUs, there + will be at least one CPU keeping the scheduling-clock interrupt + going, even if all CPUs are otherwise idle. + + Better handling of this situation is ongoing work. + +* Some process-handling operations still require the occasional + scheduling-clock tick. These operations include calculating CPU + load, maintaining sched average, computing CFS entity vruntime, + computing avenrun, and carrying out load balancing. They are + currently accommodated by scheduling-clock tick every second + or so. On-going work will eliminate the need even for these + infrequent scheduling-clock ticks. diff --git a/Documentation/timers/timekeeping.rst b/Documentation/timers/timekeeping.rst new file mode 100644 index 000000000000..f83e98852e2c --- /dev/null +++ b/Documentation/timers/timekeeping.rst @@ -0,0 +1,180 @@ +=========================================================== +Clock sources, Clock events, sched_clock() and delay timers +=========================================================== + +This document tries to briefly explain some basic kernel timekeeping +abstractions. It partly pertains to the drivers usually found in +drivers/clocksource in the kernel tree, but the code may be spread out +across the kernel. + +If you grep through the kernel source you will find a number of architecture- +specific implementations of clock sources, clockevents and several likewise +architecture-specific overrides of the sched_clock() function and some +delay timers. + +To provide timekeeping for your platform, the clock source provides +the basic timeline, whereas clock events shoot interrupts on certain points +on this timeline, providing facilities such as high-resolution timers. +sched_clock() is used for scheduling and timestamping, and delay timers +provide an accurate delay source using hardware counters. + + +Clock sources +------------- + +The purpose of the clock source is to provide a timeline for the system that +tells you where you are in time. For example issuing the command 'date' on +a Linux system will eventually read the clock source to determine exactly +what time it is. + +Typically the clock source is a monotonic, atomic counter which will provide +n bits which count from 0 to (2^n)-1 and then wraps around to 0 and start over. +It will ideally NEVER stop ticking as long as the system is running. It +may stop during system suspend. + +The clock source shall have as high resolution as possible, and the frequency +shall be as stable and correct as possible as compared to a real-world wall +clock. It should not move unpredictably back and forth in time or miss a few +cycles here and there. + +It must be immune to the kind of effects that occur in hardware where e.g. +the counter register is read in two phases on the bus lowest 16 bits first +and the higher 16 bits in a second bus cycle with the counter bits +potentially being updated in between leading to the risk of very strange +values from the counter. + +When the wall-clock accuracy of the clock source isn't satisfactory, there +are various quirks and layers in the timekeeping code for e.g. synchronizing +the user-visible time to RTC clocks in the system or against networked time +servers using NTP, but all they do basically is update an offset against +the clock source, which provides the fundamental timeline for the system. +These measures does not affect the clock source per se, they only adapt the +system to the shortcomings of it. + +The clock source struct shall provide means to translate the provided counter +into a nanosecond value as an unsigned long long (unsigned 64 bit) number. +Since this operation may be invoked very often, doing this in a strict +mathematical sense is not desirable: instead the number is taken as close as +possible to a nanosecond value using only the arithmetic operations +multiply and shift, so in clocksource_cyc2ns() you find: + + ns ~= (clocksource * mult) >> shift + +You will find a number of helper functions in the clock source code intended +to aid in providing these mult and shift values, such as +clocksource_khz2mult(), clocksource_hz2mult() that help determine the +mult factor from a fixed shift, and clocksource_register_hz() and +clocksource_register_khz() which will help out assigning both shift and mult +factors using the frequency of the clock source as the only input. + +For real simple clock sources accessed from a single I/O memory location +there is nowadays even clocksource_mmio_init() which will take a memory +location, bit width, a parameter telling whether the counter in the +register counts up or down, and the timer clock rate, and then conjure all +necessary parameters. + +Since a 32-bit counter at say 100 MHz will wrap around to zero after some 43 +seconds, the code handling the clock source will have to compensate for this. +That is the reason why the clock source struct also contains a 'mask' +member telling how many bits of the source are valid. This way the timekeeping +code knows when the counter will wrap around and can insert the necessary +compensation code on both sides of the wrap point so that the system timeline +remains monotonic. + + +Clock events +------------ + +Clock events are the conceptual reverse of clock sources: they take a +desired time specification value and calculate the values to poke into +hardware timer registers. + +Clock events are orthogonal to clock sources. The same hardware +and register range may be used for the clock event, but it is essentially +a different thing.

It partly pertains to the drivers usually found in -drivers/clocksource in the kernel tree, but the code may be spread out -across the kernel. - -If you grep through the kernel source you will find a number of architecture- -specific implementations of clock sources, clockevents and several likewise -architecture-specific overrides of the sched_clock() function and some -delay timers. - -To provide timekeeping for your platform, the clock source provides -the basic timeline, whereas clock events shoot interrupts on certain points -on this timeline, providing facilities such as high-resolution timers. -sched_clock() is used for scheduling and timestamping, and delay timers -provide an accurate delay source using hardware counters. - - -Clock sources -------------- - -The purpose of the clock source is to provide a timeline for the system that -tells you where you are in time. For example issuing the command 'date' on -a Linux system will eventually read the clock source to determine exactly -what time it is. - -Typically the clock source is a monotonic, atomic counter which will provide -n bits which count from 0 to (2^n)-1 and then wraps around to 0 and start over. -It will ideally NEVER stop ticking as long as the system is running. It -may stop during system suspend. - -The clock source shall have as high resolution as possible, and the frequency -shall be as stable and correct as possible as compared to a real-world wall -clock. It should not move unpredictably back and forth in time or miss a few -cycles here and there. - -It must be immune to the kind of effects that occur in hardware where e.g. -the counter register is read in two phases on the bus lowest 16 bits first -and the higher 16 bits in a second bus cycle with the counter bits -potentially being updated in between leading to the risk of very strange -values from the counter. - -When the wall-clock accuracy of the clock source isn't satisfactory, there -are various quirks and layers in the timekeeping code for e.g. synchronizing -the user-visible time to RTC clocks in the system or against networked time -servers using NTP, but all they do basically is update an offset against -the clock source, which provides the fundamental timeline for the system. -These measures does not affect the clock source per se, they only adapt the -system to the shortcomings of it. - -The clock source struct shall provide means to translate the provided counter -into a nanosecond value as an unsigned long long (unsigned 64 bit) number. -Since this operation may be invoked very often, doing this in a strict -mathematical sense is not desirable: instead the number is taken as close as -possible to a nanosecond value using only the arithmetic operations -multiply and shift, so in clocksource_cyc2ns() you find: - - ns ~= (clocksource * mult) >> shift - -You will find a number of helper functions in the clock source code intended -to aid in providing these mult and shift values, such as -clocksource_khz2mult(), clocksource_hz2mult() that help determine the -mult factor from a fixed shift, and clocksource_register_hz() and -clocksource_register_khz() which will help out assigning both shift and mult -factors using the frequency of the clock source as the only input. - -For real simple clock sources accessed from a single I/O memory location -there is nowadays even clocksource_mmio_init() which will take a memory -location, bit width, a parameter telling whether the counter in the -register counts up or down, and the timer clock rate, and then conjure all -necessary parameters. - -Since a 32-bit counter at say 100 MHz will wrap around to zero after some 43 -seconds, the code handling the clock source will have to compensate for this. -That is the reason why the clock source struct also contains a 'mask' -member telling how many bits of the source are valid. This way the timekeeping -code knows when the counter will wrap around and can insert the necessary -compensation code on both sides of the wrap point so that the system timeline -remains monotonic. - - -Clock events ------------- - -Clock events are the conceptual reverse of clock sources: they take a -desired time specification value and calculate the values to poke into -hardware timer registers. - -Clock events are orthogonal to clock sources.

If that qualifier is also used in the bus_find_device() prototype, it will be possible to pass the same match() callback function to both bus_find_device() and class_find_device(), which will allow some optimizations to be made in order to avoid code duplication going forward. Also with that, constify the "data" parameter as it is passed as a const to the match function. For this reason, change the prototype of bus_find_device() to match the prototype of class_find_device() and adjust its callers to use the const qualifier in accordance with the new prototype of it.

This has been a problem in many ways: first of all, it goes through the hardware event transition (from GPU register write, HD-audio controller trigger, and finally to HD-audio unsolicited event handling), which is often unreliable and may miss some opportunities. Second, each unsol event handling and ELD read-up need the explicit power up / down when the codec is in the runtime suspend. Last but not least, which is the most important, the hotplug wakeup may be missed when the HD-audio controller is in runtime suspend. Especially the last point is a big problem due to the recent change relevant with vga_switcheroo that forcibly enables the runtime PM for AMD HDMI controllers. These issues are solved by introducing the audio component; the hotplug notification is done by a direct function callback, which is more accurate and reliable, and it can be processed without the actual hardware access, i.e. no runtime PM trigger is needed, and the HD-audio gets the event even if it's in runtime suspend. The same for ELD query, as it's read directly from the cached ELD bytes stored in the DRM driver, hence the whole hardware access can be skipped. So here it is: this patch implements the audio component binding with AMD/ATI and Nouveau DRM drivers. The biggest difference from i915 implementation is that this binding is fully optional and it can be enabled asynchronously on the fly. That is, the driver will switch from the HD-audio unsolicited event to the notify callback once when the DRM component gets bound. Similarly, when DRM driver gets unloaded, the HDMI event handling returns to the legacy mode, too. Also, another difference from i915 is that the new code registers the component in the codec driver, while i915 HDMI codec assumes the component binding was already done in the HD-audio controller driver. Hence the new code does need to de-register the component binding at the codec exit, too. Some other details: - The match component ops assumes that both VGA and HD-audio controller PCI entries belong to the same PCI bus, and only accepts such an entry. - The pin2port audio_ops is implemented with assumption of the fixed widget layout. For AMD, it's starting from 3, with step 2 (3, 5, 7, ...), while for Nvidia, it's starting from 4, with step 1 (4, 5, 6, ...) As of this patch, the corresponding component isn't implemented in DRM side, so this change alone won't give any benefit. By the following changes in DRM sides, the mission will be completed.

SOF allocates memory for hdac_device and hda_hda_priv with kzalloc. Make them device-managed instead so that they will be freed when the SOF driver is unloaded. Because of the above change, hda_codec is device-managed and it will be freed when the ASoC device is removed. Freeing the codec in snd_hda_codec_dev_release() leads to kernel panic while unloading and reloading the ASoC driver. So, avoid freeing the hda_codec for ASoC driver. This is done in the same patch to avoid bisect failure.

I.e. after boot: - Connect sound source to Line-In jack; - Connect headphone to HP jack; - Run following commands: $ amixer set 'Headphone' 80% $ amixer set 'Headphone Mux' LINE_IN Change VAG power on/off control according to the following algorithm: - turn VAG power ON on the 1st incoming event. - keep it ON if there is any active VAG consumer (ADC/DAC/HP/Line-In). - turn VAG power OFF when there is the latest consumer's pre-down event come. - always delay after VAG power OFF to avoid pop. - delay after VAG power ON if the initiative consumer is Line-In, this prevents pop during line-in muxing. According to the data sheet [1], to avoid any pops/clicks, the outputs should be muted during input/output routing changes.

In current implementation of ALSA firewire stack, the quirk is handled by 'struct amdtp_stream.ctx_data.tx.first_dbc' with value 0x02. However, the value comes from reverse engineering. It's better to handle this quirk without the explicit value. In a process to parse CIP header, the quirk of data block counter affects decision of sequence index in sequence-multiplexed data channel; i.e. MIDI conformant data channel. In Fireworks, the index is decided by the number of data blocks from top of the same CIP, thus the value of data block counter is useless. This commit adds CIP_UNALIGHED_DBC flag and obsoletes the explicit value for this quirk.

This is expected by ALSA core as it resets the buffer state as part of prepare (see snd_pcm_do_prepare()). Fix the issue by forcing reconfiguration of the FW with STREAM_PCM_PARAMS in prepare(). Use combined logic to handle prepare and the existing flow to reprogram hw-params after system suspend. Without the fix, first call to pcm pointer() will return an invalid hw_ptr and application may immediately observe XRUN status, unless "start_threshold" SW parameter is set to maximum value by the application.

SOF Linux driver needs to know for each platform how to map the section type with the corresponding memory BAR. So, this patch introduces get_bar_index, a new operation inside snd_sof_dsp_ops. Intel platforms, usually load all the section in a contiguous memory area (usually denoted by sdev->mmio_bar) so things are relatively simple there. Anyhow, on i.MX8 IRAM and DRAM for example are mapped to distinct BARs. By default, if no get_bar function is provided the core implementation will always return sdev->mmio_bar so that there will be no need for a change to existing Intel code.

And when resuming from suspend mode, it checks hda controller & codec status to detect headphone hotplug event. Now this patch does the same job in SOF runtime pm functions. And we need to check all the non-hdmi codecs for some cases like playback with HDMI or capture with DMIC connected to dsp. In these cases, only controller is active and codecs are suspended, so codecs can't send unsolicited event to controller. The jack polling operation will activate codecs and unsolicited event can work even codecs become suspended later. Tested on whiskylake with hda codecs.

Later when system suspend is done, the stream tag for the remaining active stream is released by SOF driver. After system resume, hda codec driver restores the stream tag for the active pcm stream, but SOF goes to assign a new one, which now doesn't match with the stream tag used by codec driver, and this causes DMA to fail receiving data, leading to unrecoverable XRUN condition in FW. For stream tag is stored in both hda codec and SOF driver, it shouldn't be released only in SOF driver. This patch just keeps the stream information in dma data and checks whether there is a stored DMA data for stream resuming from S3 and restores it. And it also removes DMA data when the stream is released. Tested on Whiskey Lake platform.

But, some of them are implemented as snd_soc_dai_xxx(), but others are directly using dai->driver->ops->xxx. Because of it, the code is not easy to read. This patch creats new soc-dai.c and moves snd_soc_dai_xxx() functions into it. One exception is snd_soc_dai_is_dummy() which is based on soc-utils local variable. We need to keep it as-is there. Others which is directly using dai->driver->ops->xxx will be implemented at soc-dai.c by incremental patches.

IPC module is not some kind of extension, as it is the case for snd_hda_ext_core which is separated from snd_hda_core - legacy hda interface. It's as much core Skylake module as snd_soc_skl is. Statement backed up by existence of circular dependency between this two. To eliminate said problem, struct skl_sst has been created. From that very momment, Skylake has been plagued by header errors (incomplete structs, unknown references etc.) whenever something new is to be added or code is cleaned up. As this design is being corrected, struct skl_sst is no longer needed, so combine it with struct skl. To avoid ambiguity when searching for skl stuff (struct skl *skl) it has also been renamed to skl_dev. No functional changes.

charset=UTF-8 Content-Transfer-Encoding: 8bit As both modules are core part of Skylake driver and none can live without the other, combine snd_soc_skl_ipc and snd_soc_skl. It's highly probable IPC module was to be treated as an interface for platform specific code implementations e.g.: possibility of existence of BXT specific code without SKL one. However, most funtionalities are being inherited from one DSP firmware to another, and thus this assumption fails. skl-sst, bxt-sst and cnl-sst are not individuals pointing respectively to SKL (cAVS 1.5), BXT (cAVS 1.5+) & CNL (cAVS 1.8) standalone implementations. Code found within these is shared among all platforms whenever necessary to avoid code duplication and reduce development burden. Merge also helps in cleaning up internal code in future changes.

This configuration structure is made of: - cpc (chunks per cycle) - ibs (input buffer size) - obs (output buffer size) - is_pages (memory pages required) - audio_fmt (self explanatory) Skylake topology accepts following tokens: MCPS, CPS and CPC. All of these are directly connected. Moreover, assigning one of these allows to calculate the remaining two. In simplest scenario and assuming 1ms scheduling, following is true: CPS = CPC times 1000 MCPS = CPS times 1000 000 Note: these calculations vary depending on scenario and scheduling requirements. Given the current implementation, userspace is allowed to provide different values for all three causing informational chaos. On top of that, struct skl_base_cfg which represents base module configuration, incorrectly takes CPS param instead of CPC. This ambiguity may lead to user unintentionally providing improper values to DSP firmware and thus impacting module scheduling in unexpected fashion. Fix by making MCPS and CPS topology params obsolete and relying solely on CPC value.

Rather than trying to check the return value everywhere, which would be relatively intrusive, at least make sure we don't use an uninitialized value.

For those platforms, the SOF or SST drivers need to be used. This patch provides an automatic way of detecting the presence of DMICs using NHTL information reported by the BIOS. A kernel kconfig option or a kernel module parameter provide an opt-in means of stopping the probe. The kernel would then look for an alternate driver registered for the same PCI ID to probe. With this capability, distros no longer have to blacklist snd-hda-intel, but still need to make sure the SOF/SST drivers are functional by providing the relevant firmware and topology files in /lib/firmware/intel The coexistence between SOF and SST drivers and their dynamic detection is not addressed by this patch, different mechanisms need to be used, e.g. DMI-based quirks.

Also the struct snd_soc_pcm_runtime does not have real struct snd_pcm. This might a problem if the functions used by a codec on codec to codec link expect these structures to exist, and keep on existing during the life of the codec. For example, it is the case of the hdmi-codec, which uses snd_pcm_add_chmap_ctls(). For the controls to works, the pcm and substream must to exist. This change is first step, it create pcm (and substreams) for codec to codec links, in the same way as dpcm backend links.

The function can work or not, but the code logic should never do something different based on this. Also, if a debugfs call fails, userspace is notified with an error in the log, so no need to log the error again. Because we no longer need to check the return value, there's no need to save the dentry returned by debugfs. Just use the dentry in the file pointer if we really need to figure out the "name" of the file being opened.

Reply header may contain some vital information including, but not limited to, received payload size. Some IPCs have entire payload found within RX header instead. Content and value of said header is context dependent and may vary between firmware versions and target platform. Current model does not allow such IPCs to function at all. Rather than appending yet another parameter to an already long list of such for sst_ipc_tx_message_XXXs, declare message container in form of struct sst_ipc_message and add them to parent's ipc_message declaration. Align haswell, baytrail and skylake with updated request-reply model and modify their reply processing functions to save RX header within message container.

This was because some platforms require the uncached pages and the handling of page flags had to be done locally in the driver code. Since the recent change in ALSA core memory allocator, we can simply pass SNDRV_DMA_TYPE_DEV_UC for the uncached pages, and the only difference became about this type to be passed to the core allocator. That is, it's good time for cleaning up the mess. This patch changes the allocation code in HD-audio core to call the core allocator directly so that we get rid of dma_alloc_pages and dma_free_pages io_ops. If a driver needs the uncached pages, it has to set bus->dma_type right after the bus initialization. This is merely a code refactoring and shouldn't bring any behavior changes.

This is because some platform (notably Tegra SoC) requires the word-aligned access. But it's rather a rare case, and other platforms suffer from the penalties by indirect calls unnecessarily. This patch is an attempt to optimize and cleanup for this situation. Now the special aligned access is used only when a new kconfig CONFIG_SND_HDA_ALIGNED_MMIO is set. And the HD-audio core itself provides the aligned MMIO access helpers instead of the driver side. If Kconfig isn't set (as default), the standard helpers like readl() or writel() are used directly. A couple of places in ASoC Intel drivers have the access via io_ops reg_writel(), and they are replaced with the direct writel() calls. And now with this patch, the whole bus->io_ops becomes empty, so it's dropped completely. The bus initialization functions are changed accordingly as well to drop the whole bus->io_ops.

It's supposedly for making the code independent from HD-audio bus drivers. However, this is error-prone, and above all, the SOF driver has already dependency on HD-audio bus driver when CONFIG_SND_SOF_HDA is set. That is, if this Kconfig is set, there is no reason to avoid the call to the proper bus init function. Also, the ext_ops that is set at bus initialization can be better handled inside sof_hda_bus_init(). We don't need to refer this outside the bus initialization. So this patch addresses these issues: - sof_hda_bus_init() calls nothing but snd_hdac_ext_bus_init() when CONFIG_SND_SOF_HDA is set. Otherwise some fields are initialized locally like before for avoiding the dependency. - ext_ops is referred inside sof_hda_bus_init(). The ext_ops argument of snd_hda_bus_init() is dropped.

First step in reducing the code duplication is to introduce generic functions: * sof_get_windows * sof_fw_ready that will replace, in the first step, the specific implementation related to baytrail related platforms: * byt_get_windows * byt_fw_ready So we are basically moving code from intel/byt.c to loader.c keeping in mind that mbox_offset is a per platform constant so we need to use newly introduced snd_sof_dsp_get_mailbox_offset / snd_sof_dsp_get_window_offset in order to get the correct mbox offset / window offset value. Also, bar is a per platform constant so we use snd_sof_dsp_get_bar_index instead of the hardcoded BYT_DSP_BAR.

This works when it's called from the normal code paths. However, it may lead to a dead lock when it's called from the audio component notifier. Namely, the DAPM update involves with the runtime PM, and it eventually calls again the audio component get_power() ops. Since i915 driver already takes a mutex around the audio component ops calls, we'll eventually get the mutex doubly. As a workaround, in this patch, only the jack state is updated in the code path from hdac_hdmi_eld_notify_cb(), and the DAPM update is deferred to a work so that it's processed in another context.

Here, .name is used to fallback in case of no codec. But, we already have this kind of component finding method by snd_soc_dai_link_component and soc_find_component(). We shouldn't have duplicated implementation to do same things. This patch adds snd_soc_dai_link_component support to finding aux_dev. Now, no driver is using only .name. All drivers are using codec_name and/or codec_of_node. This means no driver is finding component from .name so far. (Actually almost all drivers are using .name as just "device name", not for finding component...) This patch 1) add snd_soc_dai_link_component support for aux_dev. legacy style will be removed if all drivers are switched to new style. 2) try to find component via snd_soc_dai_link_component. Then, it doesn't try to find via .name, because no driver is using it so far.

If found the data is extracted to be part of component loading and initialization. If binary data exceeds the ipc max size, loading fails with error as large message support is only implemented in set_get_data method. So make the process loading use set_get_data to enable large parameters in component initialization. Also refactor the process component loading function as it digs out 3 times almost identical information of related controls. This is redundant, looks ugly and makes it difficult to understand the mechanism. So make a function out of fetching the control data and use it in process loading.

Actually this fifo_size field would have been required in the position report correction for VIA chipset, but due to the lack of the fifo_size set for capture streams, snd-hda-intel driver fetches the register by itself. This patch straightens and simplifies the code by setting the fifo_size field for both playback and capture streams, and use it in the HD-audio controller driver.

That is, the reason of this call and the release by the counter-part function snd_hdac_bus_remove_device() is just to assure that the unsol event gets notified to the codec. But the current implementation of the unsol notification wouldn't work properly when the codec is still in a premature init state. So this patch tries to work around it by delaying the caddr_tbl[] registration at the point of snd_hdac_device_register(). Also, the order of snd_hdac_bus_remove_device() and device_del() calls are shuffled to make sure that the unsol event is masked before deleting the device.

This works fine most of the cases but it can not handle setups when the same DAI is used by different rtd, for example: pcm3168a have two DAIs: one for Playback and one for Capture. If the codec is connected to a single CPU DAI we need to have two dai_link to support both playback and capture. In this case the snd_pcm_ops callbacks can be executed in parallel causing unexpected races in DAI drivers. By moving the pcm_mutex up to card level this can be solved while - hopefully - not breaking other setups.

However, if there are two or more DAIs, uniphier_aio_dai_suspend() are called multiple times, and double reset assersion will cause. This patch defines the counter that has the number of DAIs at first, and whenever uniphier_aio_dai_suspend() are called, it decrements the counter.

We've been using the oversample_rate previously because in the former SoCs, the BCLK's parent is MCLK, which in turn is being used to generate the oversample rate, so we end up with something like this: oversample = mclk_rate / sampling_rate bclk_div = oversample / word_size / channels So, bclk_div = mclk_rate / sampling_rate / word_size / channels. And this is actually better, since the oversampling ratio only plays a role because the MCLK is its parent, not because of what BCLK is supposed to be. Furthermore, that assumption of MCLK being the parent has been broken on newer SoCs, so let's use the proper formula, and have the parent rate as an argument.

This used to be controlled through a bunch of booleans, however this proved to be quite impractical, especially since a bunch of SoCs forgot to set those parameters and therefore were broken from that point of view.

For this, we have to assure that the configuration registers look the same when capture and playback are initiated. This patch fixes a bug in which the controller is in master mode and the hw_params() callback fails for the second audio stream. The fail occurs because the divisors are calculated after comparing the configuration registers for capture and playback. The fix consists in calculating the divisors before comparing the configuration registers. BCLK and LRC are then configured and started only if the controller is not already running.

This should harden against the OOB access cases with malformed descriptors that have been recently frequently reported by fuzzers. The existing descriptor checks are still kept although they become superfluous after this patch. They'll be cleaned up eventually later.

Also each parser is split into the function for readability. Now, a slight behavior change by this cleanup is the handling of processing and extension units. Formerly we've dealt with them differently between UAC1/2 and UAC3; the latter returns an error if no input sources are available, while the former continues to parse. In this patch, unify the behavior in all cases: when input sources are available, it parses recursively, then override the type and the id, as well as channel information if not provided yet.

This is for keeping the link up to get the proper notification for ELD hotplug. As explained in the commit 37a3a98ef601 ("ALSA: hda - Enable runtime PM only for discrete GPU"), this keep-power-up behavior is rather a stop-gap solution until the ELD notification via audio component. And now we finally got the audio component for these graphics drivers via commit ade49db337a9 ("ALSA: hda/hdmi - Allow audio component for AMD/ATI and Nvidia HDMI"), so it's time to change. This patch makes HD-audio controller again runtime-suspendable when the device gets bound with audio component in HDMI codec driver. For making it easier to access from the codec driver, move the flag into the common hda_bus object instead of hda_intel flag. Also rename it to keep_power, to indicate the actual meaning.

This commit allows userspace applications can transmit and receive PCM frames and MIDI messages for this model via ALSA PCM interface and RawMidi/Sequencer interfaces. The device supports MOTU protocol version 3. Unlike the other devices, the device is simply designed. The size of data block is fixed to 10 quadlets during available sampling rates (44.1 - 96.0 kHz). Each data block includes 1 source packet header, 2 data chunks for messages, 8 data chunks for PCM samples and 2 data chunks for padding to quadlet alignment. The device has no MIDI, optical, BNC and AES/EBU interfaces.

This patch enables all speakers and also fixes muting when headphones are plugged in. The speaker layout is as follows: pin 0x15 Front Left / Front Right pin 0x18 Front Center / Subwoofer pin 0x1b Rear Left / Rear Right (Surround) The quirk will be enabled automatically on this hardware, but can also be activated manually via the model=aspire-ethos module parameter. Caveat: pin 0x1b is shared between headphones jack and surround speakers. When headphones are plugged in, the surround speakers get muted automatically by the hardware, however all other speakers remain unmuted. Currently it's not possible to make use of the generic automute function in the driver, because such shared pins are not supported. If we would change the pin settings to identify the pin as headphones, the surround channel and thus the ability to select 5.1 profiles would get lost. This quirk solves the above problem by monitoring jack state of 0x1b and by connecting/disconnecting all remaining speaker pins when something gets plugged in or unplugged from the headphones jack port.

This device has no functionality to process audio signal and MIDI messages. Instead, it transfers control messages to host system corresponding to operations for some faders, buttons and knobs on its surface. Unlike the other devices in this series, the control messages are transmitted by asynchronous transactions. Some registers of device are used for registration of destination address for the transaction. The transaction includes quadlet-aligned data up to 32 quadlets. Userspace applications can receive the transaction and parse it for control message via Linux FireWire subsystem, without any support by ALSA firewire-tascam driver. Therefore the driver gives no support for it. This commit removes placeholder for FE-8 and add some comment for its functionalities as notes. $ python2 linux-firewire-utils/src/crpp < ~/git/am-config-rom/tascam/tascam-fe8.img ROM header and bus information block ----------------------------------------------------------------- 400 040f4798 bus_info_length 4, crc_length 15, crc 18328 (should be 14256) 404 31333934 bus_name "1394" 408 20ff7002 irmc 0, cmc 0, isc 1, bmc 0, cyc_clk_acc 255, max_rec 7 (256) 40c 00022eff company_id 00022e | 410 a094dcb7 device_id ffa094dcb7 | EUI-64 00022effa094dcb7 root directory ----------------------------------------------------------------- 414 0004bccc directory_length 4, crc 48332 418 0300022e vendor 41c 0c0083c0 node capabilities per IEEE 1394 420 8d000006 --> eui-64 leaf at 438 424 d1000001 --> unit directory at 428 unit directory at 428 ----------------------------------------------------------------- 428 0003eda4 directory_length 3, crc 60836 42c 1200022e specifier id 430 13800001 version 434 d4000004 --> dependent info directory at 444 eui-64 leaf at 438 ----------------------------------------------------------------- 438 0002461e leaf_length 2, crc 17950 43c 00022eff company_id 00022e | 440 a094dcb7 device_id ffa094dcb7 | EUI-64 00022effa094dcb7 dependent info directory at 444 ----------------------------------------------------------------- 444 0002ae47 directory_length 2, crc 44615 448 81000002 --> descriptor leaf at 450 44c 82000006 --> bus dependent info leaf at 464 descriptor leaf at 450 ----------------------------------------------------------------- 450 0004a79e leaf_length 4, crc 42910 454 00000000 textual descriptor 458 00000000 minimal ASCII 45c 54415343 "TASC" 460 414d0000 "AM" bus dependent info leaf at 464 ----------------------------------------------------------------- 464 0004a7d8 leaf_length 4, crc 42968 468 00000000 46c 00000000 470 46452d38 474 00000000 Signed-off-by: Takashi Sakamoto Link: https://lore.kernel.org/r/20190906125544.13800-1-o-takashi@sakamocchi.jp Signed-off-by: Takashi Iwai --- sound/firewire/tascam/tascam.c | 4 +++- sound/firewire/tascam/tascam.h | 20 ++++++++++++++++++++ 2 files changed, 23 insertions(+), 1 deletion(-) (limited to 'sound') diff --git a/sound/firewire/tascam/tascam.c b/sound/firewire/tascam/tascam.c index 231052db5680..addc464503bc 100644 --- a/sound/firewire/tascam/tascam.c +++ b/sound/firewire/tascam/tascam.c @@ -39,6 +39,9 @@ static const struct snd_tscm_spec model_specs[] = { .midi_capture_ports = 2, .midi_playback_ports = 4, }, + // This kernel module doesn't support FE-8 because the most of features + // can be implemented in userspace without any specific support of this + // module. }; static int identify_model(struct snd_tscm *tscm) @@ -214,7 +217,6 @@ static const struct ieee1394_device_id snd_tscm_id_table[] = { .vendor_id = 0x00022e, .specifier_id = 0x00022e, }, - /* FE-08 requires reverse-engineering because it just has faders. */ {} }; MODULE_DEVICE_TABLE(ieee1394, snd_tscm_id_table); diff --git a/sound/firewire/tascam/tascam.h b/sound/firewire/tascam/tascam.h index 64a2e4d2bbfe..15bd335fa07f 100644 --- a/sound/firewire/tascam/tascam.h +++ b/sound/firewire/tascam/tascam.h @@ -129,6 +129,26 @@ struct snd_tscm { #define TSCM_OFFSET_MIDI_RX_QUAD 0x4000 +// Although FE-8 supports the above registers, it has no I/O interfaces for +// audio samples and music messages.

It has been discovered that believed to be unused GPIO pins "hookflash1" and "hookflash2" need to be set low for audible sound in handsfree and handset mode respectively. According to Amstrad E3 wiki, the purpose of both pins hasn't been clearly identified. Original Amstrad software used to produce a high pulse on them when the phone was taken off hook or recall was pressed. With the current findings, we can assume the pins provide a kind of audio mute function, separately for handset and handsfree operation modes. Commit 2afdb4c41d78 ("ARM: OMAP1: ams-delta: Fix audio permanently muted") attempted to fix the issue temporarily by hogging the GPIO pin "hookflash1" renamed to "audio_mute", however the fix occurred incomplete as it restored audible sound only for handsfree mode. Stop hogging that pin, rename the pins to "handsfree_mute" and "handset_mute" respectively and implement appropriate DAPM event callbacks for "Speaker" and "Earpiece" DAPM widgets.
