+Yocto Project Terms
+*******************
+
+Following is a list of terms and definitions users new to the Yocto Project
+development environment might find helpful. While some of these terms are
+universal, the list includes them just in case:
+
+.. glossary::
+
+ Append Files
+ Files that append build information to a recipe file. Append files are
+ known as BitBake append files and ``.bbappend`` files. The OpenEmbedded
+ build system expects every append file to have a corresponding recipe
+ (``.bb``) file. Furthermore, the append file and corresponding recipe file
+ must use the same root filename. The filenames can differ only in the
+ file type suffix used (e.g. ``formfactor_0.0.bb`` and
+ ``formfactor_0.0.bbappend``).
+
+ Information in append files extends or overrides the information in the
+ similarly-named recipe file. For an example of an append file in use, see
+ the ":ref:`dev-manual/dev-manual-common-tasks:Using .bbappend Files in
+ Your Layer`" section in the Yocto Project Development Tasks Manual.
+
+ When you name an append file, you can use the "``%``" wildcard character
+ to allow for matching recipe names. For example, suppose you have an
+ append file named as follows:
+ ::
+
+ busybox_1.21.%.bbappend
+
+ That append file
+ would match any ``busybox_1.21.``\ x\ ``.bb`` version of the recipe. So,
+ the append file would match any of the following recipe names:
+
+ .. code-block:: shell
+
+ busybox_1.21.1.bb
+ busybox_1.21.2.bb
+ busybox_1.21.3.bb
+ busybox_1.21.10.bb
+ busybox_1.21.25.bb
+
+ .. note::
+
+ The use of the " % " character is limited in that it only works
+ directly in front of the .bbappend portion of the append file's
+ name. You cannot use the wildcard character in any other location of
+ the name.
+
+ BitBake
+ The task executor and scheduler used by the OpenEmbedded build system to
+ build images. For more information on BitBake, see the :doc:`BitBake User
+ Manual <bitbake:index>`.
+
+ Board Support Package (BSP)
+ A group of drivers, definitions, and other components that provide support
+ for a specific hardware configuration. For more information on BSPs, see
+ the :ref:`bsp-guide/bsp-guide:Yocto Project Board Support Package
+ Developer's Guide`.
+
+ Build Directory
+ This term refers to the area used by the OpenEmbedded build system for
+ builds. The area is created when you ``source`` the setup environment
+ script that is found in the Source Directory
+ (i.e. :ref:`ref-manual/ref-structure:\`\`oe-init-build-env\`\``). The
+ :term:`TOPDIR` variable points to the Build Directory.
+
+ You have a lot of flexibility when creating the Build Directory.
+ Following are some examples that show how to create the directory. The
+ examples assume your :term:`Source Directory` is named ``poky``:
+
+ - Create the Build Directory inside your Source Directory and let
+ the name of the Build Directory default to ``build``:
+
+ .. code-block:: shell
+
+ $ cd $HOME/poky
+ $ source oe-init-build-env
+
+ - Create the Build Directory inside your home directory and
+ specifically name it ``test-builds``:
+
+ .. code-block:: shell
+
+ $ cd $HOME
+ $ source poky/oe-init-build-env test-builds
+
+ - Provide a directory path and specifically name the Build
+ Directory. Any intermediate folders in the pathname must exist.
+ This next example creates a Build Directory named
+ ``YP-POKYVERSION`` in your home directory within the existing
+ directory ``mybuilds``:
+
+ .. code-block:: shell
+
+ $ cd $HOME
+ $ source $HOME/poky/oe-init-build-env $HOME/mybuilds/YP-POKYVERSION
+
+ .. note::
+
+ By default, the Build Directory contains :term:`TMPDIR` , which is a
+ temporary directory the build system uses for its work. TMPDIR cannot
+ be under NFS. Thus, by default, the Build Directory cannot be under
+ NFS. However, if you need the Build Directory to be under NFS, you can
+ set this up by setting TMPDIR in your local.conf file to use a local
+ drive. Doing so effectively separates TMPDIR from TOPDIR , which is the
+ Build Directory.
+
+ Build Host
+ The system used to build images in a Yocto Project Development
+ environment. The build system is sometimes referred to as the development
+ host.
+
+ Classes
+ Files that provide for logic encapsulation and inheritance so that
+ commonly used patterns can be defined once and then easily used in
+ multiple recipes. For reference information on the Yocto Project classes,
+ see the ":ref:`ref-manual/ref-classes:Classes`" chapter. Class files end with the
+ ``.bbclass`` filename extension.
+
+ Configuration File
+ Files that hold global definitions of variables, user-defined variables,
+ and hardware configuration information. These files tell the OpenEmbedded
+ build system what to build and what to put into the image to support a
+ particular platform.
+
+ Configuration files end with a ``.conf`` filename extension. The
+ :file:`conf/local.conf` configuration file in the :term:`Build Directory`
+ contains user-defined variables that affect every build. The
+ :file:`meta-poky/conf/distro/poky.conf` configuration file defines Yocto
+ "distro" configuration variables used only when building with this
+ policy. Machine configuration files, which are located throughout the
+ :term:`Source Directory`, define variables for specific hardware and are
+ only used when building for that target (e.g. the
+ :file:`machine/beaglebone.conf` configuration file defines variables for
+ the Texas Instruments ARM Cortex-A8 development board).
+
+ Container Layer
+ Layers that hold other layers. An example of a container layer is
+ OpenEmbedded's `meta-openembedded
+ <https://github.com/openembedded/meta-openembedded>`_ layer. The
+ ``meta-openembedded`` layer contains many ``meta-*`` layers.
+
+ Cross-Development Toolchain
+ In general, a cross-development toolchain is a collection of software
+ development tools and utilities that run on one architecture and allow you
+ to develop software for a different, or targeted, architecture. These
+ toolchains contain cross-compilers, linkers, and debuggers that are
+ specific to the target architecture.
+
+ The Yocto Project supports two different cross-development toolchains:
+
+ - A toolchain only used by and within BitBake when building an image for a
+ target architecture.
+
+ - A relocatable toolchain used outside of BitBake by developers when
+ developing applications that will run on a targeted device.
+
+ Creation of these toolchains is simple and automated. For information on
+ toolchain concepts as they apply to the Yocto Project, see the
+ ":ref:`overview-manual/overview-manual-concepts:Cross-Development
+ Toolchain Generation`" section in the Yocto Project Overview and Concepts
+ Manual. You can also find more information on using the relocatable
+ toolchain in the :ref:`sdk-manual/sdk-manual:Yocto Project Application
+ Development and the Extensible Software Development Kit (eSDK)` manual.
+
+ Extensible Software Development Kit (eSDK)
+ A custom SDK for application developers. This eSDK allows developers to
+ incorporate their library and programming changes back into the image to
+ make their code available to other application developers.
+
+ For information on the eSDK, see the :ref:`sdk-manual/sdk-manual:Yocto
+ Project Application Development and the Extensible Software Development
+ Kit (eSDK)` manual.
+
+ Image
+ An image is an artifact of the BitBake build process given a collection of
+ recipes and related Metadata. Images are the binary output that run on
+ specific hardware or QEMU and are used for specific use-cases. For a list
+ of the supported image types that the Yocto Project provides, see the
+ ":ref:`ref-manual/ref-images:Images`" chapter.
+
+ Layer
+ A collection of related recipes. Layers allow you to consolidate related
+ metadata to customize your build. Layers also isolate information used
+ when building for multiple architectures. Layers are hierarchical in
+ their ability to override previous specifications. You can include any
+ number of available layers from the Yocto Project and customize the build
+ by adding your layers after them. You can search the Layer Index for
+ layers used within Yocto Project.
+
+ For introductory information on layers, see the
+ ":ref:`overview-manual/overview-manual-yp-intro:The Yocto Project Layer
+ Model`" section in the Yocto Project Overview and Concepts Manual. For
+ more detailed information on layers, see the
+ ":ref:`dev-manual/dev-manual-common-tasks:Understanding and Creating
+ Layers`" section in the Yocto Project Development Tasks Manual. For a
+ discussion specifically on BSP Layers, see the ":ref:`bsp-guide/bsp:BSP
+ Layers`" section in the Yocto Project Board Support Packages (BSP)
+ Developer's Guide.
+
+ Metadata
+ A key element of the Yocto Project is the Metadata that
+ is used to construct a Linux distribution and is contained in the
+ files that the :term:`OpenEmbedded Build System`
+ parses when building an image. In general, Metadata includes recipes,
+ configuration files, and other information that refers to the build
+ instructions themselves, as well as the data used to control what
+ things get built and the effects of the build. Metadata also includes
+ commands and data used to indicate what versions of software are
+ used, from where they are obtained, and changes or additions to the
+ software itself (patches or auxiliary files) that are used to fix
+ bugs or customize the software for use in a particular situation.
+ OpenEmbedded-Core is an important set of validated metadata.
+
+ In the context of the kernel ("kernel Metadata"), the term refers to
+ the kernel config fragments and features contained in the
+ :yocto_git:`yocto-kernel-cache </cgit/cgit.cgi/yocto-kernel-cache>`
+ Git repository.
+
+ OpenEmbedded-Core (OE-Core)
+ OE-Core is metadata comprised of
+ foundational recipes, classes, and associated files that are meant to
+ be common among many different OpenEmbedded-derived systems,
+ including the Yocto Project. OE-Core is a curated subset of an
+ original repository developed by the OpenEmbedded community that has
+ been pared down into a smaller, core set of continuously validated
+ recipes. The result is a tightly controlled and an quality-assured
+ core set of recipes.
+
+ You can see the Metadata in the ``meta`` directory of the Yocto
+ Project :yocto_git:`Source Repositories <>`.
+
+ OpenEmbedded Build System
+ The build system specific to the Yocto
+ Project. The OpenEmbedded build system is based on another project
+ known as "Poky", which uses :term:`BitBake` as the task
+ executor. Throughout the Yocto Project documentation set, the
+ OpenEmbedded build system is sometimes referred to simply as "the
+ build system". If other build systems, such as a host or target build
+ system are referenced, the documentation clearly states the
+ difference.
+
+ .. note::
+
+ For some historical information about Poky, see the
+ Poky
+ term.
+
+ Package
+ In the context of the Yocto Project, this term refers to a
+ recipe's packaged output produced by BitBake (i.e. a "baked recipe").
+ A package is generally the compiled binaries produced from the
+ recipe's sources. You "bake" something by running it through BitBake.
+
+ It is worth noting that the term "package" can, in general, have
+ subtle meanings. For example, the packages referred to in the
+ "`Required Packages for the Build
+ Host <#required-packages-for-the-build-host>`__" section are compiled
+ binaries that, when installed, add functionality to your Linux
+ distribution.
+
+ Another point worth noting is that historically within the Yocto
+ Project, recipes were referred to as packages - thus, the existence
+ of several BitBake variables that are seemingly mis-named, (e.g.
+ :term:`PR`, :term:`PV`, and
+ :term:`PE`).
+
+ Package Groups
+ Arbitrary groups of software Recipes. You use
+ package groups to hold recipes that, when built, usually accomplish a
+ single task. For example, a package group could contain the recipes
+ for a company's proprietary or value-add software. Or, the package
+ group could contain the recipes that enable graphics. A package group
+ is really just another recipe. Because package group files are
+ recipes, they end with the ``.bb`` filename extension.
+
+ Poky
+ Poky, which is pronounced *Pock*-ee, is a reference embedded
+ distribution and a reference test configuration. Poky provides the
+ following:
+
+ - A base-level functional distro used to illustrate how to customize
+ a distribution.
+
+ - A means by which to test the Yocto Project components (i.e. Poky
+ is used to validate the Yocto Project).
+
+ - A vehicle through which you can download the Yocto Project.
+
+ Poky is not a product level distro. Rather, it is a good starting
+ point for customization.
+
+ .. note::
+
+ Poky began as an open-source project initially developed by
+ OpenedHand. OpenedHand developed Poky from the existing
+ OpenEmbedded build system to create a commercially supportable
+ build system for embedded Linux. After Intel Corporation acquired
+ OpenedHand, the poky project became the basis for the Yocto
+ Project's build system.
+
+ Recipe
+ A set of instructions for building packages. A recipe
+ describes where you get source code, which patches to apply, how to
+ configure the source, how to compile it and so on. Recipes also
+ describe dependencies for libraries or for other recipes. Recipes
+ represent the logical unit of execution, the software to build, the
+ images to build, and use the ``.bb`` file extension.
+
+ Reference Kit
+ A working example of a system, which includes a
+ :term:`BSP<Board Support Package (BSP)>` as well as a
+ :term:`build host<Build Host>` and other components, that can
+ work on specific hardware.
+
+ Source Directory
+ This term refers to the directory structure
+ created as a result of creating a local copy of the ``poky`` Git
+ repository ``git://git.yoctoproject.org/poky`` or expanding a
+ released ``poky`` tarball.
+
+ .. note::
+
+ Creating a local copy of the
+ poky
+ Git repository is the recommended method for setting up your
+ Source Directory.
+
+ Sometimes you might hear the term "poky directory" used to refer to
+ this directory structure.
+
+ .. note::
+
+ The OpenEmbedded build system does not support file or directory
+ names that contain spaces. Be sure that the Source Directory you
+ use does not contain these types of names.
+
+ The Source Directory contains BitBake, Documentation, Metadata and
+ other files that all support the Yocto Project. Consequently, you
+ must have the Source Directory in place on your development system in
+ order to do any development using the Yocto Project.
+
+ When you create a local copy of the Git repository, you can name the
+ repository anything you like. Throughout much of the documentation,
+ "poky" is used as the name of the top-level folder of the local copy
+ of the poky Git repository. So, for example, cloning the ``poky`` Git
+ repository results in a local Git repository whose top-level folder
+ is also named "poky".
+
+ While it is not recommended that you use tarball expansion to set up
+ the Source Directory, if you do, the top-level directory name of the
+ Source Directory is derived from the Yocto Project release tarball.
+ For example, downloading and unpacking
+ :yocto_dl:`releases/yocto/&DISTRO_REL_TAG;/&YOCTO_POKY;.tar.bz2`
+ results in a Source Directory whose root folder is named ``poky``.
+
+ It is important to understand the differences between the Source
+ Directory created by unpacking a released tarball as compared to
+ cloning ``git://git.yoctoproject.org/poky``. When you unpack a
+ tarball, you have an exact copy of the files based on the time of
+ release - a fixed release point. Any changes you make to your local
+ files in the Source Directory are on top of the release and will
+ remain local only. On the other hand, when you clone the ``poky`` Git
+ repository, you have an active development repository with access to
+ the upstream repository's branches and tags. In this case, any local
+ changes you make to the local Source Directory can be later applied
+ to active development branches of the upstream ``poky`` Git
+ repository.
+
+ For more information on concepts related to Git repositories,
+ branches, and tags, see the
+ ":ref:`overview-manual/overview-manual-development-environment:repositories, tags, and branches`"
+ section in the Yocto Project Overview and Concepts Manual.
+
+ Task
+ A unit of execution for BitBake (e.g.
+ :ref:`ref-tasks-compile`,
+ :ref:`ref-tasks-fetch`,
+ :ref:`ref-tasks-patch`, and so forth).
+
+ Toaster
+ A web interface to the Yocto Project's :term:`OpenEmbedded Build System`.
+ The interface enables you to
+ configure and run your builds. Information about builds is collected
+ and stored in a database. For information on Toaster, see the
+ :doc:`../toaster-manual/toaster-manual`.
+
+ Upstream
+ A reference to source code or repositories that are not
+ local to the development system but located in a master area that is
+ controlled by the maintainer of the source code. For example, in
+ order for a developer to work on a particular piece of code, they
+ need to first get a copy of it from an "upstream" source.
