    ABIEXTENSION
       Extension to the Application Binary Interface (ABI) field of the GNU
       canonical architecture name (e.g. "eabi").
-   
+
       ABI extensions are set in the machine include files. For example, the
       ``meta/conf/machine/include/arm/arch-arm.inc`` file sets the
-      following extension: ABIEXTENSION = "eabi"

+
+         ABIEXTENSION = "eabi"
+
    ALLOW_EMPTY
       Specifies whether to produce an output package even if it is empty.
       By default, BitBake does not produce empty packages. This default
       behavior can cause issues when there is an
       :term:`RDEPENDS` or some other hard runtime
       requirement on the existence of the package.
-   
+
       Like all package-controlling variables, you must always use them in
-      conjunction with a package name override, as in: ALLOW_EMPTY_${PN} =
-      "1" ALLOW_EMPTY_${PN}-dev = "1" ALLOW_EMPTY_${PN}-staticdev = "1"
-   
+      conjunction with a package name override, as in:
+      ::
+
+         ALLOW_EMPTY_${PN} = "1"
+         ALLOW_EMPTY_${PN}-dev = "1"
+         ALLOW_EMPTY_${PN}-staticdev = "1"
+
    ALTERNATIVE
       Lists commands in a package that need an alternative binary naming
       scheme. Sometimes the same command is provided in multiple packages.
       When this occurs, the OpenEmbedded build system needs to use the
       alternatives system to create a different binary naming scheme so the
       commands can co-exist.
-   
+
       To use the variable, list out the package's commands that also exist
       as part of another package. For example, if the ``busybox`` package
       has four commands that also exist as part of another package, you
-      identify them as follows: ALTERNATIVE_busybox = "sh sed test bracket"
+      identify them as follows:
+      ::
+
+         ALTERNATIVE_busybox = "sh sed test bracket"

       ":ref:`update-alternatives.bbclass <ref-classes-update-alternatives>`"
       section.
-   
+
    ALTERNATIVE_LINK_NAME
       Used by the alternatives system to map duplicated commands to actual
       locations. For example, if the ``bracket`` command provided by the
       ``busybox`` package is duplicated through another package, you must
       use the ``ALTERNATIVE_LINK_NAME`` variable to specify the actual
-      location: ALTERNATIVE_LINK_NAME[bracket] = "/usr/bin/["
-   
+      location:
+      ::
+
+         ALTERNATIVE_LINK_NAME[bracket] = "/usr/bin/["
+
       In this example, the binary for the ``bracket`` command (i.e. ``[``)
       from the ``busybox`` package resides in ``/usr/bin/``.
-   
+
       .. note::
-   
-         If
-         ALTERNATIVE_LINK_NAME
-         is not defined, it defaults to

-         name
-         .

       section.
-

    ALTERNATIVE_PRIORITY
       Used by the alternatives system to create default priorities for
       duplicated commands. You can use the variable to create a single
       default regardless of the command name or package, a default for
       specific duplicated commands regardless of the package, or a default
       for specific commands tied to particular packages. Here are the

       .. note::
-

          If ``ALTERNATIVE_TARGET`` is not defined, it inherits the value
-         from the
-         :term:`ALTERNATIVE_LINK_NAME`
-         variable.
-

          If ``ALTERNATIVE_LINK_NAME`` and ``ALTERNATIVE_TARGET`` are the
          same, the target for ``ALTERNATIVE_TARGET`` has "``.{BPN}``"
          appended to it.
-   
+
          Finally, if the file referenced has not been renamed, the
          alternatives system will rename it to avoid the need to rename
          alternative files in the :ref:`ref-tasks-install`
          task while retaining support for the command if necessary.

    ARCHIVER_MODE
       When used with the :ref:`archiver <ref-classes-archiver>` class,
       determines the type of information used to create a released archive.
       You can use this variable to create archives of patched source,
       original source, configured source, and so forth by employing the
-      following variable flags (varflags): ARCHIVER_MODE[src] = "original"
-      # Uses original (unpacked) source # files. ARCHIVER_MODE[src] =
-      "patched" # Uses patched source files. This is # the default.

    AS
       Minimal command and arguments needed to run the assembler.

    ASSUME_PROVIDED
       Lists recipe names (:term:`PN` values) BitBake does not
       attempt to build. Instead, BitBake assumes these recipes have already
       been built.
-   
+
       In OpenEmbedded-Core, ``ASSUME_PROVIDED`` mostly specifies native
       tools that should not be built. An example is ``git-native``, which
       when specified, allows for the Git binary from the host to be used
       rather than building ``git-native``.
-   
+
    ASSUME_SHLIBS
       Provides additional ``shlibs`` provider mapping information, which
       adds to or overwrites the information provided automatically by the
       system. Separate multiple entries using spaces.
-   
+
       As an example, use the following form to add an ``shlib`` provider of
       shlibname in packagename with the optional version:
-      shlibname:packagename[_version]
-   
+      ::
+
+         shlibname:packagename[_version]
+
       Here is an example that adds a shared library named ``libEGL.so.1``
       as being provided by the ``libegl-implementation`` package:
-      ASSUME_SHLIBS = "libEGL.so.1:libegl-implementation"
-   
+      ::
+
+         ASSUME_SHLIBS = "libEGL.so.1:libegl-implementation"

    AUTHOR
       The email address used to contact the original author or authors in
       order to send patches and forward bugs.
-   
+
    AUTO_LIBNAME_PKGS
       When the :ref:`debian <ref-classes-debian>` class is inherited,
       which is the default behavior, ``AUTO_LIBNAME_PKGS`` specifies which
       packages should be checked for libraries and renamed according to
       Debian library package naming.
-   
+
       The default value is "${PACKAGES}", which causes the debian class to
       act on all packages that are explicitly generated by the recipe.
-   
+
    AUTO_SYSLINUXMENU
       Enables creating an automatic menu for the syslinux bootloader. You
       must set this variable in your recipe. The
       :ref:`syslinux <ref-classes-syslinux>` class checks this variable.
-   
+
    AUTOREV
       When ``SRCREV`` is set to the value of this variable, it specifies to
       use the latest source revision in the repository. Here is an example:
-      SRCREV = "${AUTOREV}"
-   
+      ::
+
+         SRCREV = "${AUTOREV}"
+
       If you use the previous statement to retrieve the latest version of
       software, you need to be sure :term:`PV` contains
       ``${``\ :term:`SRCPV`\ ``}``. For example, suppose you

       tunings (i.e. "tunes") available for use by the OpenEmbedded build
       system.

       To add a tune to the list, be sure to append it with spaces using the
       "+=" BitBake operator. Do not simply replace the list by using the
       "=" operator. See the
       ":ref:`Basic Syntax <bitbake:bitbake-user-manual/bitbake-user-manual-metadata:basic syntax>`" section in the BitBake
       User Manual for more information.

    B
       The directory within the :term:`Build Directory` in
       which the OpenEmbedded build system places generated objects during a
       recipe's build process. By default, this directory is the same as the
-      :term:`S` directory, which is defined as: S =
-      "${WORKDIR}/${BP}"
-   
+      :term:`S` directory, which is defined as:
+      ::
+
+         S = "${WORKDIR}/${BP}"
+
       You can separate the (``S``) directory and the directory pointed to
       by the ``B`` variable. Most Autotools-based recipes support
       separating these directories. The build system defaults to using
       separate directories for ``gcc`` and some kernel recipes.
-   
+
    BAD_RECOMMENDATIONS
       Lists "recommended-only" packages to not install. Recommended-only
       packages are packages installed only through the
       :term:`RRECOMMENDS` variable. You can prevent any
       of these "recommended" packages from being installed by listing them
-      with the ``BAD_RECOMMENDATIONS`` variable: BAD_RECOMMENDATIONS =
-      "package_name package_name package_name ..."
-   
+      with the ``BAD_RECOMMENDATIONS`` variable:
+      ::
+
+         BAD_RECOMMENDATIONS = "package_name package_name package_name ..."
+
       You can set this variable globally in your ``local.conf`` file or you
       can attach it to a specific image recipe by using the recipe name
-      override: BAD_RECOMMENDATIONS_pn-target_image = "package_name"
-   
+      override:
+      ::
+
+         BAD_RECOMMENDATIONS_pn-target_image = "package_name"
+
       It is important to realize that if you choose to not install packages
       using this variable and some other packages are dependent on them
       (i.e. listed in a recipe's :term:`RDEPENDS`
       variable), the OpenEmbedded build system ignores your request and
       will install the packages to avoid dependency errors.
-   
+
       Support for this variable exists only when using the IPK and RPM
       packaging backend. Support does not exist for DEB.
-   
+
       See the :term:`NO_RECOMMENDATIONS` and the
       :term:`PACKAGE_EXCLUDE` variables for related
       information.
-   
+
    BASE_LIB
       The library directory name for the CPU or Application Binary
       Interface (ABI) tune. The ``BASE_LIB`` applies only in the Multilib
-      context. See the "`Combining Multiple Versions of Library Files into
-      One
-      Image <&YOCTO_DOCS_DEV_URL;#combining-multiple-versions-library-files-into-one-image>`__"
+      context. See the ":ref:`dev-manual/dev-manual-common-tasks:combining multiple versions of library files into one image`"
       section in the Yocto Project Development Tasks Manual for information
       on Multilib.
-   
+
       The ``BASE_LIB`` variable is defined in the machine include files in
       the :term:`Source Directory`. If Multilib is not
       being used, the value defaults to "lib".
-   
+
    BASE_WORKDIR
       Points to the base of the work directory for all recipes. The default
       value is "${TMPDIR}/work".
-   
+
    BB_ALLOWED_NETWORKS
       Specifies a space-delimited list of hosts that the fetcher is allowed
       to use to obtain the required source code. Following are
       considerations surrounding this variable:
-   
+
       -  This host list is only used if ``BB_NO_NETWORK`` is either not set
          or set to "0".
-   
+
       -  Limited support for wildcard matching against the beginning of
          host names exists. For example, the following setting matches
          ``git.gnu.org``, ``ftp.gnu.org``, and ``foo.git.gnu.org``.
-         BB_ALLOWED_NETWORKS = "*.gnu.org"
-   
+         ::
+
+            BB_ALLOWED_NETWORKS = "*.gnu.org"
+
          .. note::
-   
+
             The use of the "``*``" character only works at the beginning of
             a host name and it must be isolated from the remainder of the
             host name. You cannot use the wildcard character in any other
             location of the name or combined with the front part of the
             name.
-   
+
             For example, ``*.foo.bar`` is supported, while ``*aa.foo.bar``
             is not.
-   
+
       -  Mirrors not in the host list are skipped and logged in debug.
-   
+
       -  Attempts to access networks not in the host list cause a failure.
-   
+
       Using ``BB_ALLOWED_NETWORKS`` in conjunction with

    BB_DISKMON_DIRS
       Monitors disk space and available inodes during the build and allows
       you to control the build based on these parameters.
-   
+
       Disk space monitoring is disabled by default. To enable monitoring,
       add the ``BB_DISKMON_DIRS`` variable to your ``conf/local.conf`` file
       found in the :term:`Build Directory`. Use the
-      following form: BB_DISKMON_DIRS = "action,dir,threshold [...]" where:
-      action is: ABORT: Immediately abort the build when a threshold is
-      broken. STOPTASKS: Stop the build after the currently executing tasks
-      have finished when a threshold is broken. WARN: Issue a warning but
-      continue the build when a threshold is broken. Subsequent warnings
-      are issued as defined by the BB_DISKMON_WARNINTERVAL variable, which
-      must be defined in the conf/local.conf file. dir is: Any directory
-      you choose. You can specify one or more directories to monitor by
-      separating the groupings with a space. If two directories are on the
-      same device, only the first directory is monitored. threshold is:
-      Either the minimum available disk space, the minimum number of free
-      inodes, or both. You must specify at least one. To omit one or the
-      other, simply omit the value. Specify the threshold using G, M, K for
-      Gbytes, Mbytes, and Kbytes, respectively. If you do not specify G, M,
-      or K, Kbytes is assumed by default. Do not use GB, MB, or KB.
-

+               more directories to monitor by separating the

+               on the same device, only the first directory
+               is monitored.
+
+            threshold is:
+               Either the minimum available disk space,
+               the minimum number of free inodes, or
+               both.  You must specify at least one.  To
+               omit one or the other, simply omit the value.
+               Specify the threshold using G, M, K for Gbytes,
+               Mbytes, and Kbytes, respectively. If you do
+               not specify G, M, or K, Kbytes is assumed by
+               default.  Do not use GB, MB, or KB.
+
+      Here are some examples:

       The second example stops the build after all currently executing

       disk space monitoring for the directory itself occurs in this case.

    BB_DISKMON_WARNINTERVAL
       Defines the disk space and free inode warning intervals. To set these
       intervals, define the variable in your ``conf/local.conf`` file in
       the :term:`Build Directory`.
-   
+
       If you are going to use the ``BB_DISKMON_WARNINTERVAL`` variable, you
       must also use the :term:`BB_DISKMON_DIRS`
       variable and define its action as "WARN". During the build,
       subsequent warnings are issued each time disk space or number of free
       inodes further reduces by the respective interval.
-   
+
       If you do not provide a ``BB_DISKMON_WARNINTERVAL`` variable and you
       do use ``BB_DISKMON_DIRS`` with the "WARN" action, the disk
       monitoring interval defaults to the following:

-   
+      ::
+
+         BB_DISKMON_WARNINTERVAL = "50M,5K"

       When specifying the variable in your configuration file, use the
-      following form: BB_DISKMON_WARNINTERVAL =
-      "disk_space_interval,disk_inode_interval" where: disk_space_interval
-      is: An interval of memory expressed in either G, M, or K for Gbytes,

+
+      These variables cause the
       OpenEmbedded build system to issue subsequent warnings each time the
       available disk space further reduces by 50 Mbytes or the number of
       free inodes further reduces by 5 Kbytes in the ``${SSTATE_DIR}``
       directory. Subsequent warnings based on the interval occur each time
       a respective interval is reached beyond the initial warning (i.e. 1
       Gbytes and 100 Kbytes).

    BB_GENERATE_MIRROR_TARBALLS

    BB_SERVER_TIMEOUT
       Specifies the time (in seconds) after which to unload the BitBake
       server due to inactivity. Set ``BB_SERVER_TIMEOUT`` to determine how
       long the BitBake server stays resident between invocations.

    BBCLASSEXTEND
       Allows you to extend a recipe so that it builds variants of the

       "``multilib:``\ multilib_name".
-   
+
       To build a different variant of the recipe with a minimal amount of
       code, it usually is as simple as adding the following to your recipe:

+
       .. note::
-   
+
          Internally, the ``BBCLASSEXTEND`` mechanism generates recipe
          variants by rewriting variable values and applying overrides such
          as ``_class-native``. For example, to generate a native version of
          a recipe, a :term:`DEPENDS` on "foo" is rewritten
          to a ``DEPENDS`` on "foo-native".
-   
+
          Even when using ``BBCLASSEXTEND``, the recipe is only parsed once.
          Parsing once adds some limitations. For example, it is not
          possible to include a different file depending on the variant,
          since ``include`` statements are processed when the recipe is
          parsed.

    BBFILE_COLLECTIONS
       Lists the names of configured layers. These names are used to find
       the other ``BBFILE_*`` variables. Typically, each layer will append
       its name to this variable in its ``conf/layer.conf`` file.

    BBFILE_PATTERN
       Variable that expands to match files from

    BBFILES_DYNAMIC
       Activates content when identified layers are present. You identify
       the layers by the collections that the layers define.

       Use the ``BBFILES_DYNAMIC`` variable to avoid ``.bbappend`` files
       whose corresponding ``.bb`` file is in a layer that attempts to
       modify other layers through ``.bbappend`` but does not want to
       introduce a hard dependency on those other layers.

       Variable that controls how BitBake displays logs on build failure.

       If :term:`BBINCLUDELOGS` is set, specifies the
       maximum number of lines from the task log file to print when

    BBMASK
       Prevents BitBake from processing recipes and recipe append files.
-   
+
       You can use the ``BBMASK`` variable to "hide" these ``.bb`` and
       ``.bbappend`` files. BitBake ignores any recipe or recipe append
       files that match any of the expressions. It is as if BitBake does not
       see them at all. Consequently, matching files are not parsed or
       otherwise used by BitBake.
-   
+
       The values you provide are passed to Python's regular expression
       compiler. Consequently, the syntax follows Python's Regular
       Expression (re) syntax. The expressions are compared against the full
       paths to the files. For complete syntax information, see Python's
       documentation at http://docs.python.org/3/library/re.html#re.
-   
+
       The following example uses a complete regular expression to tell
       BitBake to ignore all recipe and recipe append files in the
-      ``meta-ti/recipes-misc/`` directory: BBMASK = "meta-ti/recipes-misc/"
+      ``meta-ti/recipes-misc/`` directory:
+      ::

+         BBMASK = "meta-ti/recipes-misc/"

       If you want to mask out multiple directories or recipes, you can
       specify multiple regular expression fragments. This next example
-      masks out multiple directories and individual recipes: BBMASK +=
-      "/meta-ti/recipes-misc/ meta-ti/recipes-ti/packagegroup/" BBMASK +=
-      "/meta-oe/recipes-support/" BBMASK += "/meta-foo/.*/openldap" BBMASK

+         BBMASK += "lzma"

       .. note::

          When specifying a directory name, use the trailing slash character
          to ensure you match just that directory name.
-

    BBMULTICONFIG
       Specifies each additional separate configuration when you are
       building targets with multiple configurations. Use this variable in
       your ``conf/local.conf`` configuration file. Specify a
       multiconfigname for each configuration file you are using. For
       example, the following line specifies three configuration files:

       Specifies the list of packages to be added to the image. You should

    COREBASE
       Specifies the parent directory of the OpenEmbedded-Core Metadata
       layer (i.e. ``meta``).
-   
+
       It is an important distinction that ``COREBASE`` points to the parent
       of this layer and not the layer itself. Consider an example where you
       have cloned the Poky Git repository and retained the ``poky`` name
       for your local copy of the repository. In this case, ``COREBASE``
       points to the ``poky`` folder because it is the parent directory of
       the ``poky/meta`` layer.

    COREBASE_FILES
       Lists files from the :term:`COREBASE` directory that
       should be copied other than the layers listed in the
       ``bblayers.conf`` file. The ``COREBASE_FILES`` variable exists for
       the purpose of copying metadata from the OpenEmbedded build system
       into the extensible SDK.
-   
+
       Explicitly listing files in ``COREBASE`` is needed because it
       typically contains build directories and other files that should not
       normally be copied into the extensible SDK. Consequently, the value
       of ``COREBASE_FILES`` is used in order to only copy the files that
       are actually needed.
-

    CPP
       The minimal command and arguments used to run the C preprocessor.
-   
+
    CPPFLAGS
       Specifies the flags to pass to the C pre-processor (i.e. to both the
       C and the C++ compilers). This variable is exported to an environment
       variable and thus made visible to the software being built during the
       compilation step.
-   
+
       Default initialization for ``CPPFLAGS`` varies depending on what is
       being built:
-

    DEBIAN_NOAUTONAME
       When the :ref:`debian <ref-classes-debian>` class is inherited,
       which is the default behavior, ``DEBIAN_NOAUTONAME`` specifies a
       particular package should not be renamed according to Debian library
       package naming. You must use the package name as an override when you
       set this variable. Here is an example from the ``fontconfig`` recipe:
-      DEBIAN_NOAUTONAME_fontconfig-utils = "1"
-   
+      ::
+
+         DEBIAN_NOAUTONAME_fontconfig-utils = "1"
+
    DEBIANNAME
       When the :ref:`debian <ref-classes-debian>` class is inherited,
       which is the default behavior, ``DEBIANNAME`` allows you to override
       the library name for an individual package. Overriding the library
       name in these cases is rare. You must use the package name as an
       override when you set this variable. Here is an example from the
-      ``dbus`` recipe: DEBIANNAME_${PN} = "dbus-1"

+      ``dbus`` recipe:
+      ::

    DEBUG_BUILD
       Specifies to build packages with debugging information. This
       influences the value of the ``SELECTED_OPTIMIZATION`` variable.
-   
+
    DEBUG_OPTIMIZATION
       The options to pass in ``TARGET_CFLAGS`` and ``CFLAGS`` when
       compiling a system for debugging. This variable defaults to "-O
       -fno-omit-frame-pointer ${DEBUG_FLAGS} -pipe".
-   
+
    DEFAULT_PREFERENCE
       Specifies a weak bias for recipe selection priority.
-   
+
       The most common usage of this is variable is to set it to "-1" within
       a recipe for a development version of a piece of software. Using the
       variable in this way causes the stable version of the recipe to build
       by default in the absence of ``PREFERRED_VERSION`` being used to
       build the development version.
-   
+
       .. note::
-   
+
          The bias provided by
          DEFAULT_PREFERENCE
          is weak and is overridden by
          BBFILE_PRIORITY
          if that variable is different between two layers that contain
          different versions of the same recipe.
-   
+
    DEFAULTTUNE
       The default CPU and Application Binary Interface (ABI) tunings (i.e.
       the "tune") used by the OpenEmbedded build system. The
       ``DEFAULTTUNE`` helps define
       :term:`TUNE_FEATURES`.
-   
+
       The default tune is either implicitly or explicitly set by the
       machine (:term:`MACHINE`). However, you can override
       the setting using available tunes as defined with
       :term:`AVAILTUNES`.
-   
+
    DEPENDS
       Lists a recipe's build-time dependencies. These are dependencies on
       other recipes whose contents (e.g. headers and shared libraries) are
       needed by the recipe at build time.
-

       As another example, ``DEPENDS`` can also be used to add utilities
       that run on the build machine during the build. For example, a recipe

       The ``DISTRO`` variable corresponds to a distribution configuration
       file whose root name is the same as the variable's argument and whose
       filename extension is ``.conf``. For example, the distribution
       configuration file for the Poky distribution is named ``poky.conf``
       and resides in the ``meta-poky/conf/distro`` directory of the
       :term:`Source Directory`.

       Distribution configuration files are located in a ``conf/distro``
       directory within the :term:`Metadata` that contains the
       distribution configuration. The value for ``DISTRO`` must not contain
       spaces, and is typically all lower-case.

       Best practices dictate that you accomplish this by using

       .. note::
-

          When extending ``FILESEXTRAPATHS``, be sure to use the immediate

          Also, include the trailing separating colon character if you are
          prepending. The trailing colon character is necessary because you
          are directing BitBake to extend the path by prepending directories
          to the search path.

       You can take advantage of this searching behavior in useful ways. For

       permissions setting table, you should place it in your layer or the

    HOST_CC_ARCH
       Specifies architecture-specific compiler flags that are passed to the
       C compiler.
-

       Default initialization for ``HOST_CC_ARCH`` varies depending on what
       is being built:
-   
+
       -  :term:`TARGET_CC_ARCH` when building for the
          target
-

       -  ``BUILDSDK_CC_ARCH`` when building for an SDK (i.e.
          ``nativesdk-``)
-

    HOST_OS
       Specifies the name of the target operating system, which is normally
       the same as the :term:`TARGET_OS`. The variable can
       be set to "linux" for ``glibc``-based systems and to "linux-musl" for
       ``musl``. For ARM/EABI targets, there are also "linux-gnueabi" and
       "linux-musleabi" values possible.
-

    HOST_PREFIX
       Specifies the prefix for the cross-compile toolchain. ``HOST_PREFIX``
       is normally the same as :term:`TARGET_PREFIX`.
-   
+
    HOST_SYS
       Specifies the system, including the architecture and the operating
       system, for which the build is occurring in the context of the
       current recipe.
-   
+
       The OpenEmbedded build system automatically sets this variable based
       on :term:`HOST_ARCH`,
       :term:`HOST_VENDOR`, and
       :term:`HOST_OS` variables.
-

       -  Given a native recipe on a 32-bit x86 machine running Linux, the
          value is "i686-linux".

       A more efficient way of dealing with this situation is to set the

       help define the recipe revision.

       The following provides an example that shows how to use the

       can use the variable to set the ``PR`` values in each recipe. You

    KERNEL_IMAGE_MAXSIZE
       Specifies the maximum size of the kernel image file in kilobytes. If
       ``KERNEL_IMAGE_MAXSIZE`` is set, the size of the kernel image file is
       checked against the set value during the
       :ref:`ref-tasks-sizecheck` task. The task fails if

       ``KERNEL_IMAGE_MAXSIZE`` is useful for target devices that have a
       limited amount of space in which the kernel image must be stored.

       You can use the ``KERNEL_MODULE_AUTOLOAD`` variable anywhere that it
       can be recognized by the kernel recipe or by an out-of-tree kernel
       module recipe (e.g. a machine configuration file, a distribution

       Including ``KERNEL_MODULE_AUTOLOAD`` causes the OpenEmbedded build
       system to populate the ``/etc/modules-load.d/modname.conf`` file with
       the list of modules to be auto-loaded on boot. The modules appear

       known as "whitelisting" license flags. For more information, see the
-      "`Enabling Commercially Licensed
-      Recipes <&YOCTO_DOCS_DEV_URL;#enabling-commercially-licensed-recipes>`__"

       section in the Yocto Project Development Tasks Manual.

    LICENSE_PATH
       Path to additional licenses used during the build. By default, the
       OpenEmbedded build system uses ``COMMON_LICENSE_DIR`` to define the
       directory that holds common license text used during the build. The
       ``LICENSE_PATH`` variable allows you to extend that location to other
-      areas that have additional licenses: LICENSE_PATH +=
-      "path-to-additional-common-licenses"

    LINUX_KERNEL_TYPE
       Defines the kernel type to be used in assembling the configuration.
       The linux-yocto recipes define "standard", "tiny", and "preempt-rt"
-      kernel types. See the "`Kernel
-      Types <&YOCTO_DOCS_KERNEL_DEV_URL;#kernel-types>`__" section in the
+      kernel types. See the ":ref:`kernel-dev/kernel-dev-advanced:kernel types`"
+      section in the
       Yocto Project Linux Kernel Development Manual for more information on
       kernel types.
-   
+
       If you do not specify a ``LINUX_KERNEL_TYPE``, it defaults to
       "standard". Together with :term:`KMACHINE`, the
       ``LINUX_KERNEL_TYPE`` variable defines the search arguments used by
       the kernel tools to find the appropriate description within the
       kernel :term:`Metadata` with which to build out the sources
       and configuration.
-   
+
    LINUX_VERSION
       The Linux version from ``kernel.org`` on which the Linux kernel image
       being built using the OpenEmbedded build system is based. You define
       this variable in the kernel recipe. For example, the
       ``linux-yocto-3.4.bb`` kernel recipe found in
       ``meta/recipes-kernel/linux`` defines the variables as follows:
-      LINUX_VERSION ?= "3.4.24"
-   
+      ::
+
+         LINUX_VERSION ?= "3.4.24"
+
       The ``LINUX_VERSION`` variable is used to define :term:`PV`
-      for the recipe: PV = "${LINUX_VERSION}+git${SRCPV}"
-   
+      for the recipe:
+      ::
+
+         PV = "${LINUX_VERSION}+git${SRCPV}"
+
    LINUX_VERSION_EXTENSION
       A string extension compiled into the version string of the Linux
       kernel built with the OpenEmbedded build system. You define this
       variable in the kernel recipe. For example, the linux-yocto kernel
-      recipes all define the variable as follows: LINUX_VERSION_EXTENSION
-      ?= "-yocto-${:term:`LINUX_KERNEL_TYPE`}"
-   
+      recipes all define the variable as follows:
+      ::
+
+         LINUX_VERSION_EXTENSION ?= "-yocto-${LINUX_KERNEL_TYPE}"
+
       Defining this variable essentially sets the Linux kernel
       configuration item ``CONFIG_LOCALVERSION``, which is visible through
       the ``uname`` command. Here is an example that shows the extension
-      assuming it was set as previously shown: $ uname -r 3.7.0-rc8-custom
-   
+      assuming it was set as previously shown:
+      ::
+
+         $ uname -r
+         3.7.0-rc8-custom
+
    LOG_DIR
       Specifies the directory to which the OpenEmbedded build system writes
       overall log files. The default directory is ``${TMPDIR}/log``.
-   
+
       For the directory containing logs specific to each task, see the
       :term:`T` variable.
-   
+
    MACHINE
       Specifies the target device for which the image is built. You define
       ``MACHINE`` in the ``local.conf`` file found in the
       :term:`Build Directory`. By default, ``MACHINE`` is set to
       "qemux86", which is an x86-based architecture machine to be emulated
-      using QEMU: MACHINE ?= "qemux86"
-   
+      using QEMU:
+      ::
+
+         MACHINE ?= "qemux86"
+
       The variable corresponds to a machine configuration file of the same
       name, through which machine-specific configurations are set. Thus,
       when ``MACHINE`` is set to "qemux86" there exists the corresponding
       ``qemux86.conf`` machine configuration file, which can be found in
       the :term:`Source Directory` in
       ``meta/conf/machine``.

+
       The ``PACKAGECONFIG`` variable itself specifies a space-separated
       list of the features to enable. Following the features, you can
       determine the behavior of each feature by providing up to six
       order-dependent arguments, which are separated by commas. You can
       omit any argument you like but must retain the separating commas. The
       order is important and specifies the following:
-   
+
       1. Extra arguments that should be added to the configure script
          argument list (:term:`EXTRA_OECONF` or
          :term:`PACKAGECONFIG_CONFARGS`) if
          the feature is enabled.
-   
+
       2. Extra arguments that should be added to ``EXTRA_OECONF`` or
          ``PACKAGECONFIG_CONFARGS`` if the feature is disabled.
-   
+
       3. Additional build dependencies (:term:`DEPENDS`)
          that should be added if the feature is enabled.
-   
+
       4. Additional runtime dependencies (:term:`RDEPENDS`)
          that should be added if the feature is enabled.
-   
+
       5. Additional runtime recommendations
          (:term:`RRECOMMENDS`) that should be added if
          the feature is enabled.
-   
+
       6. Any conflicting (that is, mutually exclusive) ``PACKAGECONFIG``
          settings for this feature.
-   
+
       Consider the following ``PACKAGECONFIG`` block taken from the
       ``librsvg`` recipe. In this example the feature is ``gtk``, which has
       three arguments that determine the feature's behavior.
-      PACKAGECONFIG[gtk] = "--with-gtk3,--without-gtk3,gtk+3" The
+      ::
+
+         PACKAGECONFIG[gtk] = "--with-gtk3,--without-gtk3,gtk+3"
+
+      The
       ``--with-gtk3`` and ``gtk+3`` arguments apply only if the feature is
       enabled. In this case, ``--with-gtk3`` is added to the configure
       script argument list and ``gtk+3`` is added to ``DEPENDS``. On the
       other hand, if the feature is disabled say through a ``.bbappend``
       file in another layer, then the second argument ``--without-gtk3`` is
       added to the configure script instead.
-   
+
       The basic ``PACKAGECONFIG`` structure previously described holds true
       regardless of whether you are creating a block or changing a block.
       When creating a block, use the structure inside your recipe.
-   
+
       If you want to change an existing ``PACKAGECONFIG`` block, you can do
       so one of two ways:
-   
+
       -  *Append file:* Create an append file named
          recipename\ ``.bbappend`` in your layer and override the value of
          ``PACKAGECONFIG``. You can either completely override the
-         variable: PACKAGECONFIG = "f4 f5" Or, you can just append the

+         ::
+
+            PACKAGECONFIG_append = " f4"
+
       -  *Configuration file:* This method is identical to changing the
          block through an append file except you edit your ``local.conf``
          or ``mydistro.conf`` file. As with append files previously
          described, you can either completely override the variable:
          PACKAGECONFIG_pn-recipename = "f4 f5" Or, you can just amend the
-         variable: PACKAGECONFIG_append_pn-recipename = " f4"

    PACKAGECONFIG_CONFARGS
       A space-separated list of configuration options generated from the
       :term:`PACKAGECONFIG` setting.
-

       Classes such as :ref:`autotools <ref-classes-autotools>` and
       :ref:`cmake <ref-classes-cmake>` use ``PACKAGECONFIG_CONFARGS`` to

    PN
       This variable can have two separate functions depending on the
       context: a recipe name or a resulting package name.
-   
+
       ``PN`` refers to a recipe name in the context of a file used by the
       OpenEmbedded build system as input to create a package. The name is
       normally extracted from the recipe file name. For example, if the
       recipe is named ``expat_2.0.1.bb``, then the default value of ``PN``
       will be "expat".
-   
+
       The variable refers to a package name in the context of a file
       created or produced by the OpenEmbedded build system.
-   
+
       If applicable, the ``PN`` variable also contains any special suffix
       or prefix. For example, using ``bash`` to build packages for the
       native machine, ``PN`` is ``bash-native``. Using ``bash`` to build
       packages for the target and for Multilib, ``PN`` would be ``bash``
       and ``lib64-bash``, respectively.
-   
+
    PNBLACKLIST
       Lists recipes you do not want the OpenEmbedded build system to build.
       This variable works in conjunction with the
       :ref:`blacklist <ref-classes-blacklist>` class, which is inherited
       globally.
-   
+
       To prevent a recipe from being built, use the ``PNBLACKLIST``
       variable in your ``local.conf`` file. Here is an example that
-      prevents ``myrecipe`` from being built: PNBLACKLIST[myrecipe] = "Not
-      supported by our organization."

       Specifies a list of functions to call once the OpenEmbedded build

-

       If you need to pass the SDK path to a command within a function, you
       can use ``${SDK_DIR}``, which points to the parent directory used by
       the OpenEmbedded build system when creating SDK output. See the
       :term:`SDK_DIR` variable for more information.
-

    POPULATE_SDK_POST_TARGET_COMMAND
       Specifies a list of functions to call once the OpenEmbedded build

       preferred provider). You should always suffix this variable with the
       name of the provided item. And, you should define the variable using
       the preferred recipe's name (:term:`PN`). Here is a common

    PREFERRED_VERSION
       If multiple versions of recipes exist, this variable determines which
       version is given preference. You must always suffix the variable with
       the :term:`PN` you want to select, and you should set the
       :term:`PV` accordingly for precedence.
-   
+
       The ``PREFERRED_VERSION`` variable supports limited wildcard use
       through the "``%``" character. You can use the character to match any
       number of characters, which can be useful when specifying versions
       that contain long revision numbers that potentially change. Here are

          location of the string.
-   
+
       The specified version is matched against :term:`PV`, which
       does not necessarily match the version part of the recipe's filename.
       For example, consider two recipes ``foo_1.2.bb`` and ``foo_git.bb``
-      where ``foo_git.bb`` contains the following assignment: PV =
-      "1.1+git${SRCPV}" In this case, the correct way to select

       ``foo_git.bb`` is by using an assignment such as the following:
-      PREFERRED_VERSION_foo = "1.1+git%" Compare that previous example
+      ::
+
+         PREFERRED_VERSION_foo = "1.1+git%"

       against the following incorrect example, which does not work:
-      PREFERRED_VERSION_foo = "git"
-   
+      ::
+
+         PREFERRED_VERSION_foo = "git"
+
       Sometimes the ``PREFERRED_VERSION`` variable can be set by
       configuration files in a way that is hard to change. You can use

    RDEPENDS
       Lists runtime dependencies of a package. These dependencies are other
       packages that must be installed in order for the package to function
       correctly. As an example, the following assignment declares that the
       package ``foo`` needs the packages ``bar`` and ``baz`` to be

       The names of the packages you list within ``RDEPENDS`` must be the
       names of other packages - they cannot be recipe names. Although
       package names and recipe names usually match, the important point

       Because the ``RDEPENDS`` variable applies to packages being built,
       you should always use the variable in a form with an attached package
       name (remember that a single recipe can build multiple packages). For
       example, suppose you are building a development package that depends

       Because the ``RRECOMMENDS`` variable applies to packages being built,

    SDK_LOCAL_CONF_BLACKLIST
       A list of variables not allowed through from the OpenEmbedded build

    SDK_PACKAGE_ARCHS
       Specifies a list of architectures compatible with the SDK machine.
       This variable is set automatically and should not normally be
       hand-edited. Entries are separated using spaces and listed in order
       of priority. The default value for ``SDK_PACKAGE_ARCHS`` is "all any
       noarch ${SDK_ARCH}-${SDKPKGSUFFIX}".
-   
+
    SDK_POSTPROCESS_COMMAND
       Specifies a list of functions to call once the OpenEmbedded build
       system creates the SDK. You can specify functions separated by
       semicolons: SDK_POSTPROCESS_COMMAND += "function; ... "
-   
+
       If you need to pass an SDK path to a command within a function, you
       can use ``${SDK_DIR}``, which points to the parent directory used by
       the OpenEmbedded build system when creating SDK output. See the
       :term:`SDK_DIR` variable for more information.
-   
+
    SDK_PREFIX
       The toolchain binary prefix used for ``nativesdk`` recipes. The
       OpenEmbedded build system uses the ``SDK_PREFIX`` value to set the
       :term:`TARGET_PREFIX` when building
       ``nativesdk`` recipes. The default value is "${SDK_SYS}-".
-   
+
    SDK_RECRDEP_TASKS
       A list of shared state tasks added to the extensible SDK. By default,
-      the following tasks are added: do_populate_lic do_package_qa

+
+      Despite the default value of "" for the
       ``SDK_RECRDEP_TASKS`` variable, the above four tasks are always added
       to the SDK. To specify tasks beyond these four, you need to use the
       ``SDK_RECRDEP_TASKS`` variable (e.g. you are defining additional
       tasks that are needed in order to build
       :term:`SDK_TARGETS`).
-   
+
    SDK_SYS
       Specifies the system, including the architecture and the operating
       system, for which the SDK will be built.
-   
+
       The OpenEmbedded build system automatically sets this variable based
       on :term:`SDK_ARCH`,
       :term:`SDK_VENDOR`, and
       :term:`SDK_OS`. You do not need to set the ``SDK_SYS``
       variable yourself.
-   
+
    SDK_TARGET_MANIFEST
       The manifest file for the target part of the SDK. This file lists all
       the installed packages that make up the target part of the SDK. The

-   
+
    SDK_TARGETS
       A list of targets to install from shared state as part of the
       standard or extensible SDK installation. The default value is "${PN}"
       (i.e. the image from which the SDK is built).
-   
+
       The ``SDK_TARGETS`` variable is an internal variable and typically
       would not be changed.
-   
+
    SDK_TITLE
       The title to be printed when running the SDK installer. By default,
       this title is based on the :term:`DISTRO_NAME` or

       as it will be when installed into the default
       :term:`SDKPATH`.
-   
+
    SECTION
       The section in which packages should be categorized. Package
       management utilities can make use of this variable.
-   
+
    SELECTED_OPTIMIZATION
       Specifies the optimization flags passed to the C compiler when
       building for the target. The flags are passed through the default
       value of the :term:`TARGET_CFLAGS` variable.
-   
+
       The ``SELECTED_OPTIMIZATION`` variable takes the value of
       ``FULL_OPTIMIZATION`` unless ``DEBUG_BUILD`` = "1". If that is the
       case, the value of ``DEBUG_OPTIMIZATION`` is used.
-   
+
    SERIAL_CONSOLE
       Defines a serial console (TTY) to enable using
       `getty <https://en.wikipedia.org/wiki/Getty_(Unix)>`__. Provide a
       value that specifies the baud rate followed by the TTY device name

+
    SERIAL_CONSOLES_CHECK
       Specifies serial consoles, which must be listed in
       :term:`SERIAL_CONSOLES`, to check against
       ``/proc/console`` before enabling them using getty. This variable
       allows aliasing in the format: <device>:<alias>. If a device was
       listed as "sclp_line0" in ``/dev/`` and "ttyS0" was listed in
-      ``/proc/console``, you would do the following: SERIAL_CONSOLES_CHECK
-      = "slcp_line0:ttyS0" This variable is currently only supported with
-      SysVinit (i.e. not with systemd).
-   
+      ``/proc/console``, you would do the following: ::
+
+         SERIAL_CONSOLES_CHECK = "slcp_line0:ttyS0"
+
+      This variable is currently only supported with SysVinit (i.e. not
+      with systemd).
+
    SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS
       A list of recipe dependencies that should not be used to determine
       signatures of tasks from one recipe when they depend on tasks from
-      another recipe. For example: SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS +=
-      "intone->mplayer2"
-   
+      another recipe. For example: ::
+
+         SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS += "intone->mplayer2"
+
       In the previous example, ``intone`` depends on ``mplayer2``.
-   
+
       You can use the special token ``"*"`` on the left-hand side of the
       dependency to match all recipes except the one on the right-hand
-      side. Here is an example: SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS +=
-      "*->quilt-native"
-   
+      side. Here is an example: ::
+
+         SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS += "*->quilt-native"

       for musl libc. For ARM/EABI targets, "linux-gnueabi" and
       "linux-musleabi" possible values exist.
-

    TARGET_PREFIX
       Specifies the prefix used for the toolchain binary target tools.
-   
+
       Depending on the type of recipe and the build target,
       ``TARGET_PREFIX`` is set as follows:
-   
+
       -  For recipes building for the target machine, the value is
          "${:term:`TARGET_SYS`}-".
-

       -  For native recipes, the build system sets the variable to the
          value of ``BUILD_PREFIX``.

       -  For native SDK recipes (``nativesdk``), the build system sets the
          variable to the value of ``SDK_PREFIX``.

    TARGET_SYS
       Specifies the system, including the architecture and the operating
       system, for which the build is occurring in the context of the
       current recipe.
-   
+
       The OpenEmbedded build system automatically sets this variable based
       on :term:`TARGET_ARCH`,
       :term:`TARGET_VENDOR`, and
       :term:`TARGET_OS` variables.

       Consider these two examples:
-   
+

       With additional layers, it is possible to use a pre-compiled external
       toolchain. One example is the Sourcery G++ Toolchain. The support for
       this toolchain resides in the separate Mentor Graphics
       ``meta-sourcery`` layer at
       http://github.com/MentorEmbedded/meta-sourcery/.
-

       The layer's ``README`` file contains information on how to use the
       Sourcery G++ Toolchain as an external toolchain. In summary, you must
       be sure to add the layer to your ``bblayers.conf`` file in front of
       the ``meta`` layer and then set the ``EXTERNAL_TOOLCHAIN`` variable
       in your ``local.conf`` file to the location in which you installed
       the toolchain.

       A target controller is a class that defines how an image gets
       deployed on a target and how a target is started. A layer can extend
       the controllers by adding a module in the layer's
       ``/lib/oeqa/controllers`` directory and by inheriting the

    TEST_SUITES
       An ordered list of tests (modules) to run against an image when

          Currently, there is only support for running these tests under
          QEMU.
-

       Tests include ``ping``, ``ssh``, ``df`` among others. You can add

       image. Tests that are not applicable are skipped.
-   
+
       The order in which tests are run is important. Tests that depend on
       another test must appear later in the list than the test on which
       they depend. For example, if you append the list of tests with two
       tests (``test_A`` and ``test_B``) where ``test_B`` is dependent on

    TESTIMAGE_AUTO
       Automatically runs the series of automated tests for images when an
       image is successfully built. Setting ``TESTIMAGE_AUTO`` to "1" causes
       any image that successfully builds to automatically boot under QEMU.
       Using the variable also adds in dependencies so that any SDK for
       which testing is requested is automatically built first.
-   
+
       These tests are written in Python making use of the ``unittest``
       module, and the majority of them run commands on the target system
       over ``ssh``. You can set this variable to "1" in your ``local.conf``

+
    THISDIR
       The directory in which the file BitBake is currently parsing is
       located. Do not manually set this variable.
-   
+
    TIME
       The time the build was started. Times appear using the hour, minute,
       and second (HMS) format (e.g. "140159" for one minute and fifty-nine
       seconds past 1400 hours).
-   
+
    TMPDIR
       This variable is the base directory the OpenEmbedded build system
       uses for all build output and intermediate files (other than the
       shared state cache). By default, the ``TMPDIR`` variable points to
       ``tmp`` within the :term:`Build Directory`.
-   
+
       If you want to establish this directory in a location other than the
       default, you can uncomment and edit the following statement in the
       ``conf/local.conf`` file in the :term:`Source Directory`:
-      #TMPDIR = "${TOPDIR}/tmp" An
-      example use for this scenario is to set ``TMPDIR`` to a local disk,
+      ::
+
+         #TMPDIR = "${TOPDIR}/tmp"
+
+      An example use for this scenario is to set ``TMPDIR`` to a local disk,
       which does not use NFS, while having the Build Directory use NFS.
-   
+
       The filesystem used by ``TMPDIR`` must have standard filesystem
       semantics (i.e. mixed-case files are unique, POSIX file locking, and
       persistent inodes). Due to various issues with NFS and bugs in some
       implementations, NFS does not meet this minimum requirement.
       Consequently, ``TMPDIR`` cannot be on NFS.

       ``TUNE_ARCH`` is tied closely to
       :term:`TARGET_ARCH`, which defines the target
