<title>The Yocto Project Development Environment</title>
<para>
This chapter takes a look at the Yocto Project development
environment and also provides a detailed look at what goes on during
development in that environment.
The chapter provides Yocto Project Development environment concepts that
help you understand how work is accomplished in an open source environment,
which is very different as compared to work accomplished in a closed,
proprietary environment.
This chapter specifically addresses open source philosophy, using the
Yocto Project in a team environment, source repositories, Yocto Project
terms, licensing, the open source distributed version control system Git,
workflows, bug tracking, and how to submit changes.
</para>
<section id='open-source-philosophy'>
<title>Open Source Philosophy</title>
<para>
Open source philosophy is characterized by software development
directed by peer production and collaboration through an active
community of developers.
Contrast this to the more standard centralized development models
used by commercial software companies where a finite set of developers
produces a product for sale using a defined set of procedures that
ultimately result in an end product whose architecture and source
material are closed to the public.
</para>
<para>
Open source projects conceptually have differing concurrent agendas,
approaches, and production.
These facets of the development process can come from anyone in the
public (community) that has a stake in the software project.
The open source environment contains new copyright, licensing, domain,
and consumer issues that differ from the more traditional development
environment.
In an open source environment, the end product, source material,
and documentation are all available to the public at no cost.
</para>
<para>
A benchmark example of an open source project is the Linux kernel,
which was initially conceived and created by Finnish computer science
student Linus Torvalds in 1991.
Conversely, a good example of a non-open source project is the
<trademark class='registered'>Windows</trademark> family of operating
systems developed by
<trademark class='registered'>Microsoft</trademark> Corporation.
</para>

Philosophy

<title>Workflows</title>
<para>
This section provides workflow concepts using the Yocto Project and
Git.
In particular, the information covers basic practices that describe
roles and actions in a collaborative development environment.
<note>
If you are familiar with this type of development environment, you
might not want to read this section.

</para>
<para>
The Yocto Project files are maintained using Git in "master"
branches whose Git histories track every change and whose structures
provides branches for all diverging functionality.
Although there is no need to use Git, many open source projects do so.
<para>
</para>
For the Yocto Project, a key individual called the "maintainer" is
responsible for the "master" branch of a given Git repository.
The "master" branch is the “upstream” repository from which final or
most recent builds of the project occur.
The maintainer is responsible for accepting changes from other
developers and for organizing the underlying branch structure to
reflect release strategies and so forth.
<note>For information on finding out who is responsible for (maintains)
a particular area of code, see the
"<ulink url='&YOCTO_DOCS_DEV_URL;#how-to-submit-a-change'>Submitting a Change to the Yocto Project</ulink>"
section of the Yocto Project Development Manual.
</note>
</para>
<para>
The Yocto Project <filename>poky</filename> Git repository also has an
upstream contribution Git repository named
<filename>poky-contrib</filename>.
You can see all the branches in this repository using the web interface
of the
<ulink url='&YOCTO_GIT_URL;'>Source Repositories</ulink> organized
within the "Poky Support" area.
These branches temporarily hold changes to the project that have been
submitted or committed by the Yocto Project development team and by
community members who contribute to the project.
The maintainer determines if the changes are qualified to be moved
from the "contrib" branches into the "master" branch of the Git
repository.
</para>
<para>
Developers (including contributing community members) create and
maintain cloned repositories of the upstream "master" branch.
The cloned repositories are local to their development platforms and
are used to develop changes.
When a developer is satisfied with a particular feature or change,
they "push" the changes to the appropriate "contrib" repository.
</para>
<para>
Developers are responsible for keeping their local repository
up-to-date with "master".
They are also responsible for straightening out any conflicts that
might arise within files that are being worked on simultaneously by
more than one person.
All this work is done locally on the developer’s machine before
anything is pushed to a "contrib" area and examined at the maintainer’s
level.
</para>
<para>
A somewhat formal method exists by which developers commit changes
and push them into the "contrib" area and subsequently request that
the maintainer include them into "master".
This process is called “submitting a patch” or "submitting a change."
For information on submitting patches and changes, see the
"<ulink url='&YOCTO_DOCS_DEV_URL;#how-to-submit-a-change'>Submitting a Change to the Yocto Project</ulink>"
section in the Yocto Project Development Manual.
</para>
<para>
To summarize the development workflow: a single point of entry
exists for changes into the project’s "master" branch of the
Git repository, which is controlled by the project’s maintainer.
And, a set of developers exist who independently develop, test, and
submit changes to "contrib" areas for the maintainer to examine.
The maintainer then chooses which changes are going to become a
permanent part of the project.
</para>

</para>
<para>
While each development environment is unique, there are some best
practices or methods that help development run smoothly.
The following list describes some of these practices.
For more information about Git workflows, see the workflow topics in
the
<ulink url='http://book.git-scm.com'>Git Community Book</ulink>.
<itemizedlist>
<listitem><para>
<emphasis>Make Small Changes:</emphasis>
It is best to keep the changes you commit small as compared to
bundling many disparate changes into a single commit.
This practice not only keeps things manageable but also allows
the maintainer to more easily include or refuse changes.</para>
<para>It is also good practice to leave the repository in a
state that allows you to still successfully build your project.
In other words, do not commit half of a feature,
then add the other half as a separate, later commit.
Each commit should take you from one buildable project state
to another buildable state.
</para></listitem>
<listitem><para>
<emphasis>Use Branches Liberally:</emphasis>
It is very easy to create, use, and delete local branches in
your working Git repository.
You can name these branches anything you like.
It is helpful to give them names associated with the particular
feature or change on which you are working.
Once you are done with a feature or change and have merged it
into your local master branch, simply discard the temporary
branch.
</para></listitem>
<listitem><para>
<emphasis>Merge Changes:</emphasis>
The <filename>git merge</filename> command allows you to take
the changes from one branch and fold them into another branch.
This process is especially helpful when more than a single
developer might be working on different parts of the same
feature.
Merging changes also automatically identifies any collisions
or "conflicts" that might happen as a result of the same lines
of code being altered by two different developers.
</para></listitem>
<listitem><para>
<emphasis>Manage Branches:</emphasis>
Because branches are easy to use, you should use a system
where branches indicate varying levels of code readiness.
For example, you can have a "work" branch to develop in, a
"test" branch where the code or change is tested, a "stage"
branch where changes are ready to be committed, and so forth.
As your project develops, you can merge code across the
branches to reflect ever-increasing stable states of the
development.
</para></listitem>
<listitem><para>
<emphasis>Use Push and Pull:</emphasis>
The push-pull workflow is based on the concept of developers
"pushing" local commits to a remote repository, which is
usually a contribution repository.
This workflow is also based on developers "pulling" known
states of the project down into their local development
repositories.
The workflow easily allows you to pull changes submitted by
other developers from the upstream repository into your
work area ensuring that you have the most recent software
on which to develop.
The Yocto Project has two scripts named
<filename>create-pull-request</filename> and
<filename>send-pull-request</filename> that ship with the
release to facilitate this workflow.
You can find these scripts in the <filename>scripts</filename>
folder of the
<link linkend='source-directory'>Source Directory</link>.
For information on how to use these scripts, see the
"<ulink url='&YOCTO_DOCS_DEV_URL;#pushing-a-change-upstream'>Using Scripts to Push a Change Upstream and Request a Pull</ulink>"
section in the Yocto Project Development Manual.
</para></listitem>
<listitem><para>
<emphasis>Patch Workflow:</emphasis>
This workflow allows you to notify the maintainer through an
email that you have a change (or patch) you would like
considered for the "master" branch of the Git repository.
To send this type of change, you format the patch and then
send the email using the Git commands
<filename>git format-patch</filename> and
<filename>git send-email</filename>.
For information on how to use these scripts, see the
"<ulink url='&YOCTO_DOCS_DEV_URL;#how-to-submit-a-change'>Submitting a Change to the Yocto Project</ulink>"
section in the Yocto Project Development Manual.

<title>Git</title>
<para>
The Yocto Project makes extensive use of Git, which is a
free, open source distributed version control system.
Git supports distributed development, non-linear development,
and can handle large projects.
It is best that you have some fundamental understanding
of how Git tracks projects and how to work with Git if
you are going to use the Yocto Project for development.
This section provides a quick overview of how Git works and
provides you with a summary of some essential Git commands.

<title>Repositories, Tags, and Branches</title>
<para>
As mentioned briefly in the previous section and also in the
"<link linkend='workflows'>Workflows</link>" section,
the Yocto Project maintains source repositories at
<ulink url='&YOCTO_GIT_URL;/cgit.cgi'></ulink>.
If you look at this web-interface of the repositories, each item
is a separate Git repository.
</para>
<para>
Git repositories use branching techniques that track content
change (not files) within a project (e.g. a new feature or updated
documentation).
Creating a tree-like structure based on project divergence allows
for excellent historical information over the life of a project.
This methodology also allows for an environment from which you can
do lots of local experimentation on projects as you develop
changes or new features.
</para>
<para>
A Git repository represents all development efforts for a given
project.
For example, the Git repository <filename>poky</filename> contains
all changes and developments for Poky over the course of its
entire life.
That means that all changes that make up all releases are captured.
The repository maintains a complete history of changes.
</para>
<para>
You can create a local copy of any repository by "cloning" it
with the <filename>git clone</filename> command.
When you clone a Git repository, you end up with an identical
copy of the repository on your development system.
Once you have a local copy of a repository, you can take steps to
develop locally.
For examples on how to clone Git repositories, see the
"<ulink url='&YOCTO_DOCS_DEV_URL;#working-with-yocto-project-source-files'>Working With Yocto Project Source Files</ulink>"
section in the Yocto Project Development Manual.
</para>
<para>
It is important to understand that Git tracks content change and
not files.
Git uses "branches" to organize different development efforts.
For example, the <filename>poky</filename> repository has
several branches that include the current "&DISTRO_NAME_NO_CAP;"
branch, the "master" branch, and many branches for past
Yocto Project releases.
You can see all the branches by going to
<ulink url='&YOCTO_GIT_URL;/cgit.cgi/poky/'></ulink> and
clicking on the
<filename><ulink url='&YOCTO_GIT_URL;/cgit.cgi/poky/refs/heads'>[...]</ulink></filename>
link beneath the "Branch" heading.
</para>
<para>
Each of these branches represents a specific area of development.
The "master" branch represents the current or most recent
development.
All other branches represent offshoots of the "master" branch.
</para>
<para>
When you create a local copy of a Git repository, the copy has
the same set of branches as the original.
This means you can use Git to create a local working area
(also called a branch) that tracks a specific development branch
from the upstream source Git repository.
in other words, you can define your local Git environment to
work on any development branch in the repository.
To help illustrate, consider the following example Git commands:
<literallayout class='monospaced'>
$ cd ~
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git checkout -b &DISTRO_NAME_NO_CAP; origin/&DISTRO_NAME_NO_CAP;
</literallayout>
In the previous example after moving to the home directory, the
<filename>git clone</filename> command creates a
local copy of the upstream <filename>poky</filename> Git repository.
By default, Git checks out the "master" branch for your work.
After changing the working directory to the new local repository
(i.e. <filename>poky</filename>), the
<filename>git checkout</filename> command creates
and checks out a local branch named "&DISTRO_NAME_NO_CAP;", which
tracks the upstream "origin/&DISTRO_NAME_NO_CAP;" branch.
Changes you make while in this branch would ultimately affect
the upstream "&DISTRO_NAME_NO_CAP;" branch of the
<filename>poky</filename> repository.
</para>
<para>
It is important to understand that when you create and checkout a
local working branch based on a branch name,
your local environment matches the "tip" of that particular
development branch at the time you created your local branch,
which could be different from the files in the "master" branch
of the upstream repository.
In other words, creating and checking out a local branch based on
the "&DISTRO_NAME_NO_CAP;" branch name is not the same as
cloning and checking out the "master" branch if the repository.
Keep reading to see how you create a local snapshot of a Yocto
Project Release.
</para>
<para>
Git uses "tags" to mark specific changes in a repository.
Typically, a tag is used to mark a special point such as the final
change before a project is released.
You can see the tags used with the <filename>poky</filename> Git
repository by going to
<ulink url='&YOCTO_GIT_URL;/cgit.cgi/poky/'></ulink> and
clicking on the
<filename><ulink url='&YOCTO_GIT_URL;/cgit.cgi/poky/refs/tags'>[...]</ulink></filename>
link beneath the "Tag" heading.
</para>
<para>
Some key tags for the <filename>poky</filename> are
<filename>jethro-14.0.3</filename>,
<filename>morty-16.0.1</filename>,
<filename>pyro-17.0.0</filename>, and
<filename>&DISTRO_NAME_NO_CAP;-&POKYVERSION;</filename>.
These tags represent Yocto Project releases.
</para>
<para>
When you create a local copy of the Git repository, you also
have access to all the tags in the upstream repository.
Similar to branches, you can create and checkout a local working
Git branch based on a tag name.
When you do this, you get a snapshot of the Git repository that
reflects the state of the files when the change was made associated
with that tag.
The most common use is to checkout a working branch that matches
a specific Yocto Project release.
Here is an example:
<literallayout class='monospaced'>
$ cd ~
$ git clone git://git.yoctoproject.org/poky
$ cd poky
$ git fetch --all --tags --prune
$ git checkout tags/pyro-17.0.0 -b my-pyro-17.0.0
</literallayout>
In this example, the name of the top-level directory of your
local Yocto Project repository is <filename>poky</filename>.
After moving to the <filename>poky</filename> directory, the
<filename>git fetch</filename> command makes all the upstream
tags available locally in your repository.
Finally, the <filename>git checkout</filename> command
creates and checks out a branch named "my-pyro-17.0.0" that is
based on the specific change upstream in the repository
associated with the "pyro-17.0.0" tag.
The files in your repository now exactly match that particular
Yocto Project release as it is tagged in the upstream Git
repository.
It is important to understand that when you create and
checkout a local working branch based on a tag, your environment
matches a specific point in time and not the entire development
branch (i.e. the "tip" of the branch).

<para>
Because open source projects are open to the public, they have
different licensing structures in place.
License evolution for both Open Source and Free Software has an
interesting history.
If you are interested in this history, you can find basic information

In general, the Yocto Project is broadly licensed under the
Massachusetts Institute of Technology (MIT) License.
MIT licensing permits the reuse of software within proprietary
software as long as the license is distributed with that software.
MIT is also compatible with the GNU General Public License (GPL).
Patches to the Yocto Project follow the upstream licensing scheme.
You can find information on the MIT license
<ulink url='http://www.opensource.org/licenses/mit-license.php'>here</ulink>.
You can find information on the GNU GPL
<ulink url='http://www.opensource.org/licenses/LGPL-3.0'>here</ulink>.
</para>
<para>
When you build an image using the Yocto Project, the build process
uses a known list of licenses to ensure compliance.
You can find this list in the
<link linkend='source-directory'>Source Directory</link> at
<filename>meta/files/common-licenses</filename>.
Once the build completes, the list of all licenses found and used
during that build are kept in the
<link linkend='build-directory'>Build Directory</link>
at <filename>tmp/deploy/licenses</filename>.
</para>
<para>
If a module requires a license that is not in the base list, the
build process generates a warning during the build.
These tools make it easier for a developer to be certain of the
licenses with which their shipped products must comply.
However, even with these tools it is still up to the developer to
resolve potential licensing issues.
</para>
<para>
The base list of licenses used by the build process is a combination
of the Software Package Data Exchange (SPDX) list and the Open
Source Initiative (OSI) projects.
<ulink url='http://spdx.org'>SPDX Group</ulink> is a working group of
the Linux Foundation that maintains a specification for a standard
format for communicating the components, licenses, and copyrights
associated with a software package.
<ulink url='http://opensource.org'>OSI</ulink> is a corporation
dedicated to the Open Source Definition and the effort for reviewing
and approving licenses that conform to the Open Source Definition
(OSD).
</para>
<para>
You can find a list of the combined SPDX and OSI licenses that the
Yocto Project uses in the

<section id="user-configuration">
<title>User Configuration</title>
<para>
User configuration helps define the build.
Through user configuration, you can tell BitBake the
target architecture for which you are building the image,
where to store downloaded source, and other build properties.
</para>
<para>
The following figure shows an expanded representation of the
"User Configuration" box of the
<link linkend='general-yocto-environment-figure'>general Yocto Project Development Environment figure</link>:
</para>
<para>
<imagedata fileref="figures/user-configuration.png" align="center" />
</para>
<para>
BitBake needs some basic configuration files in order to complete
a build.
These files are <filename>*.conf</filename> files.
The minimally necessary ones reside as example files in the
<ulink url='&YOCTO_DOCS_DEV_URL;#source-directory'>Source Directory</ulink>.
For simplicity, this section refers to the Source Directory as
the "Poky Directory."
</para>
<para>
When you clone the <filename>poky</filename> Git repository or you
download and unpack a Yocto Project release, you can set up the
Source Directory to be named anything you want.
For this discussion, the cloned repository uses the default
name <filename>poky</filename>.
<note>
The Poky repository is primarily an aggregation of existing
repositories.
It is not a canonical upstream source.
</note>
</para>
<para>
The <filename>meta-poky</filename> layer inside Poky contains
a <filename>conf</filename> directory that has example
configuration files.
These example files are used as a basis for creating actual
configuration files when you source the build environment
script
(i.e.
<link linkend='structure-core-script'><filename>&OE_INIT_FILE;</filename></link>
or
<link linkend='structure-memres-core-script'><filename>oe-init-build-env-memres</filename></link>).
</para>
<para>
Sourcing the build environment script creates a
<link linkend='build-directory'>Build Directory</link>
if one does not already exist.
BitBake uses the Build Directory for all its work during builds.
The Build Directory has a <filename>conf</filename> directory that
contains default versions of your <filename>local.conf</filename>
and <filename>bblayers.conf</filename> configuration files.
These default configuration files are created only if versions
do not already exist in the Build Directory at the time you
source the build environment setup script.
</para>
<para>
Because the Poky repository is fundamentally an aggregation of
existing repositories, some users might be familiar with running
the <filename>&OE_INIT_FILE;</filename> or
<filename>oe-init-build-env-memres</filename> script in the context
of separate OpenEmbedded-Core and BitBake repositories rather than a
single Poky repository.
This discussion assumes the script is executed from within a cloned
or unpacked version of Poky.
</para>
<para>
Depending on where the script is sourced, different sub-scripts
are called to set up the Build Directory (Yocto or OpenEmbedded).
Specifically, the script
<filename>scripts/oe-setup-builddir</filename> inside the
poky directory sets up the Build Directory and seeds the directory
(if necessary) with configuration files appropriate for the
Yocto Project development environment.
<note>
The <filename>scripts/oe-setup-builddir</filename> script
uses the <filename>$TEMPLATECONF</filename> variable to
determine which sample configuration files to locate.
</note>
</para>
<para>
The <filename>local.conf</filename> file provides many
basic variables that define a build environment.
Here is a list of a few.
To see the default configurations in a <filename>local.conf</filename>
file created by the build environment script, see the
<filename>local.conf.sample</filename> in the
<filename>meta-poky</filename> layer:

<note>
Configurations set in the <filename>conf/local.conf</filename>
file can also be set in the
<filename>conf/site.conf</filename> and
<filename>conf/auto.conf</filename> configuration files.
</note>
</para>
<para>
The <filename>bblayers.conf</filename> file tells BitBake what
layers you want considered during the build.
By default, the layers listed in this file include layers
minimally needed by the build system.
However, you must manually add any custom layers you have created.
You can find more information on working with the
<filename>bblayers.conf</filename> file in the
"<ulink url='&YOCTO_DOCS_DEV_URL;#enabling-your-layer'>Enabling Your Layer</ulink>"
section in the Yocto Project Development Manual.
</para>
<para>
The files <filename>site.conf</filename> and
<filename>auto.conf</filename> are not created by the environment
initialization script.
If you want the <filename>site.conf</filename> file, you need to
create that yourself.
The <filename>auto.conf</filename> file is typically created by
an autobuilder:
<itemizedlist>
<listitem><para><emphasis><filename>site.conf</filename>:</emphasis>
You can use the <filename>conf/site.conf</filename>
configuration file to configure multiple build directories.
For example, suppose you had several build environments and
they shared some common features.
You can set these default build properties here.
A good example is perhaps the packaging format to use
through the
<link linkend='var-PACKAGE_CLASSES'><filename>PACKAGE_CLASSES</filename></link>
variable.</para>
<para>One useful scenario for using the
<filename>conf/site.conf</filename> file is to extend your
<link linkend='var-BBPATH'><filename>BBPATH</filename></link>
variable to include the path to a
<filename>conf/site.conf</filename>.
Then, when BitBake looks for Metadata using
<filename>BBPATH</filename>, it finds the
<filename>conf/site.conf</filename> file and applies your
common configurations found in the file.
To override configurations in a particular build directory,
alter the similar configurations within that build
directory's <filename>conf/local.conf</filename> file.
</para></listitem>
<listitem><para><emphasis><filename>auto.conf</filename>:</emphasis>
The file is usually created and written to by
an autobuilder.
The settings put into the file are typically the same as
you would find in the <filename>conf/local.conf</filename>
or the <filename>conf/site.conf</filename> files.
</para></listitem>
</itemizedlist>
</para>
<para>
You can edit all configuration files to further define
any particular build environment.
This process is represented by the "User Configuration Edits"
box in the figure.
</para>
<para>
When you launch your build with the
<filename>bitbake <replaceable>target</replaceable></filename>
command, BitBake sorts out the configurations to ultimately
define your build environment.
It is important to understand that the OpenEmbedded build system
reads the configuration files in a specific order:
<filename>site.conf</filename>, <filename>auto.conf</filename>,
and <filename>local.conf</filename>.
And, the build system applies the normal assignment statement
rules.
Because the files are parsed in a specific order, variable
assignments for the same variable could be affected.
For example, if the <filename>auto.conf</filename> file and
the <filename>local.conf</filename> set
<replaceable>variable1</replaceable> to different values, because
the build system parses <filename>local.conf</filename> after
<filename>auto.conf</filename>,
<replaceable>variable1</replaceable> is assigned the value from
the <filename>local.conf</filename> file.
</para>
</section>
<section id="metadata-machine-configuration-and-policy-configuration">
<title>Metadata, Machine Configuration, and Policy Configuration</title>
<para>
The previous section described the user configurations that
define BitBake's global behavior.
This section takes a closer look at the layers the build system
uses to further control the build.
These layers provide Metadata for the software, machine, and
policy.
</para>
<para>
In general, three types of layer input exist:
<itemizedlist>
<listitem><para><emphasis>Policy Configuration:</emphasis>
Distribution Layers provide top-level or general
policies for the image or SDK being built.
For example, this layer would dictate whether BitBake
produces RPM or IPK packages.</para></listitem>
<listitem><para><emphasis>Machine Configuration:</emphasis>
Board Support Package (BSP) layers provide machine
configurations.
This type of information is specific to a particular
target architecture.</para></listitem>
<listitem><para><emphasis>Metadata:</emphasis>
Software layers contain user-supplied recipe files,
patches, and append files.
</para></listitem>
</itemizedlist>
</para>
<para>
The following figure shows an expanded representation of the
Metadata, Machine Configuration, and Policy Configuration input
(layers) boxes of the
<link linkend='general-yocto-environment-figure'>general Yocto Project Development Environment figure</link>:
</para>
<para>
<imagedata fileref="figures/layer-input.png" align="center" width="8in" depth="7.5in" />
</para>
<para>
In general, all layers have a similar structure.
They all contain a licensing file
(e.g. <filename>COPYING</filename>) if the layer is to be
distributed, a <filename>README</filename> file as good practice
and especially if the layer is to be distributed, a
configuration directory, and recipe directories.
</para>
<para>
The Yocto Project has many layers that can be used.
You can see a web-interface listing of them on the
<ulink url="http://git.yoctoproject.org/">Source Repositories</ulink>
page.
The layers are shown at the bottom categorized under
"Yocto Metadata Layers."
These layers are fundamentally a subset of the
<ulink url="http://layers.openembedded.org/layerindex/layers/">OpenEmbedded Metadata Index</ulink>,
which lists all layers provided by the OpenEmbedded community.
<note>
Layers exist in the Yocto Project Source Repositories that
cannot be found in the OpenEmbedded Metadata Index.
These layers are either deprecated or experimental in nature.
</note>
</para>
<para>
BitBake uses the <filename>conf/bblayers.conf</filename> file,
which is part of the user configuration, to find what layers it
should be using as part of the build.
</para>
<para>
For more information on layers, see the
"<ulink url='&YOCTO_DOCS_DEV_URL;#understanding-and-creating-layers'>Understanding and Creating Layers</ulink>"
section in the Yocto Project Development Manual.
</para>
<section id="distro-layer">
<title>Distro Layer</title>
<para>
The distribution layer provides policy configurations for your
distribution.
Best practices dictate that you isolate these types of
configurations into their own layer.
Settings you provide in
<filename>conf/distro/<replaceable>distro</replaceable>.conf</filename> override
similar
settings that BitBake finds in your
<filename>conf/local.conf</filename> file in the Build
Directory.
</para>
<para>
The following list provides some explanation and references
for what you typically find in the distribution layer:
<itemizedlist>
<listitem><para><emphasis>classes:</emphasis>
Class files (<filename>.bbclass</filename>) hold
common functionality that can be shared among
recipes in the distribution.
When your recipes inherit a class, they take on the
settings and functions for that class.
You can read more about class files in the
"<link linkend='ref-classes'>Classes</link>" section.
</para></listitem>
<listitem><para><emphasis>conf:</emphasis>
This area holds configuration files for the
layer (<filename>conf/layer.conf</filename>),
the distribution
(<filename>conf/distro/<replaceable>distro</replaceable>.conf</filename>),
and any distribution-wide include files.
</para></listitem>
<listitem><para><emphasis>recipes-*:</emphasis>
Recipes and append files that affect common
functionality across the distribution.
This area could include recipes and append files
to add distribution-specific configuration,
initialization scripts, custom image recipes,
and so forth.</para></listitem>
</itemizedlist>
</para>
</section>
<section id="bsp-layer">
<title>BSP Layer</title>
<para>
The BSP Layer provides machine configurations.
Everything in this layer is specific to the machine for which
you are building the image or the SDK.
A common structure or form is defined for BSP layers.
You can learn more about this structure in the
<ulink url='&YOCTO_DOCS_BSP_URL;'>Yocto Project Board Support Package (BSP) Developer's Guide</ulink>.
<note>
In order for a BSP layer to be considered compliant with the
Yocto Project, it must meet some structural requirements.
</note>
</para>
<para>
The BSP Layer's configuration directory contains
configuration files for the machine
(<filename>conf/machine/<replaceable>machine</replaceable>.conf</filename>) and,
of course, the layer (<filename>conf/layer.conf</filename>).
</para>
<para>
The remainder of the layer is dedicated to specific recipes
by function: <filename>recipes-bsp</filename>,
<filename>recipes-core</filename>,
<filename>recipes-graphics</filename>, and
<filename>recipes-kernel</filename>.
Metadata can exist for multiple formfactors, graphics
support systems, and so forth.
<note>
While the figure shows several <filename>recipes-*</filename>
directories, not all these directories appear in all
BSP layers.
</note>
</para>
</section>
<section id="software-layer">
<title>Software Layer</title>
<para>
The software layer provides the Metadata for additional
software packages used during the build.
This layer does not include Metadata that is specific to the
distribution or the machine, which are found in their
respective layers.
</para>
<para>
This layer contains any new recipes that your project needs
in the form of recipe files.
</para>
</section>
</section>
<section id="sources-dev-environment">
<title>Sources</title>
<para>
In order for the OpenEmbedded build system to create an image or
any target, it must be able to access source files.
The
<link linkend='general-yocto-environment-figure'>general Yocto Project Development Environment figure</link>
represents source files using the "Upstream Project Releases",
"Local Projects", and "SCMs (optional)" boxes.
The figure represents mirrors, which also play a role in locating
source files, with the "Source Mirror(s)" box.
</para>
<para>
The method by which source files are ultimately organized is
a function of the project.
For example, for released software, projects tend to use tarballs
or other archived files that can capture the state of a release
guaranteeing that it is statically represented.
On the other hand, for a project that is more dynamic or
experimental in nature, a project might keep source files in a
repository controlled by a Source Control Manager (SCM) such as
Git.
Pulling source from a repository allows you to control
the point in the repository (the revision) from which you want to
build software.
Finally, a combination of the two might exist, which would give the
consumer a choice when deciding where to get source files.
</para>
<para>
BitBake uses the
<link linkend='var-SRC_URI'><filename>SRC_URI</filename></link>
variable to point to source files regardless of their location.
Each recipe must have a <filename>SRC_URI</filename> variable
that points to the source.
</para>
<para>
Another area that plays a significant role in where source files
come from is pointed to by the
<link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
variable.
This area is a cache that can hold previously downloaded source.
You can also instruct the OpenEmbedded build system to create
tarballs from Git repositories, which is not the default behavior,
and store them in the <filename>DL_DIR</filename> by using the
<link linkend='var-BB_GENERATE_MIRROR_TARBALLS'><filename>BB_GENERATE_MIRROR_TARBALLS</filename></link>
variable.
</para>
<para>
Judicious use of a <filename>DL_DIR</filename> directory can
save the build system a trip across the Internet when looking
for files.
A good method for using a download directory is to have
<filename>DL_DIR</filename> point to an area outside of your
Build Directory.
Doing so allows you to safely delete the Build Directory
if needed without fear of removing any downloaded source file.
</para>
<para>
The remainder of this section provides a deeper look into the
source files and the mirrors.
Here is a more detailed look at the source file area of the
base figure:
<imagedata fileref="figures/source-input.png" align="center" width="7in" depth="7.5in" />
</para>
<section id='upstream-project-releases'>
<title>Upstream Project Releases</title>
<para>
Upstream project releases exist anywhere in the form of an
archived file (e.g. tarball or zip file).
These files correspond to individual recipes.
For example, the figure uses specific releases each for
BusyBox, Qt, and Dbus.
An archive file can be for any released product that can be
built using a recipe.
</para>
</section>
<section id='local-projects'>
<title>Local Projects</title>
<para>
Local projects are custom bits of software the user provides.
These bits reside somewhere local to a project - perhaps
a directory into which the user checks in items (e.g.
a local directory containing a development source tree
used by the group).
</para>
<para>
The canonical method through which to include a local project
is to use the
<link linkend='ref-classes-externalsrc'><filename>externalsrc</filename></link>
class to include that local project.
You use either the <filename>local.conf</filename> or a
recipe's append file to override or set the
recipe to point to the local directory on your disk to pull
in the whole source tree.
</para>
<para>
For information on how to use the
<filename>externalsrc</filename> class, see the
"<link linkend='ref-classes-externalsrc'><filename>externalsrc.bbclass</filename></link>"
section.
</para>
</section>
<section id='scms'>
<title>Source Control Managers (Optional)</title>
<para>
Another place the build system can get source files from is
through an SCM such as Git or Subversion.
In this case, a repository is cloned or checked out.
The
<link linkend='ref-tasks-fetch'><filename>do_fetch</filename></link>
task inside BitBake uses
the <link linkend='var-SRC_URI'><filename>SRC_URI</filename></link>
variable and the argument's prefix to determine the correct
fetcher module.
</para>
<note>
For information on how to have the OpenEmbedded build system
generate tarballs for Git repositories and place them in the
<link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
directory, see the
<link linkend='var-BB_GENERATE_MIRROR_TARBALLS'><filename>BB_GENERATE_MIRROR_TARBALLS</filename></link>
variable.
</note>
<para>
When fetching a repository, BitBake uses the
<link linkend='var-SRCREV'><filename>SRCREV</filename></link>
variable to determine the specific revision from which to
build.
</para>
</section>
<section id='source-mirrors'>
<title>Source Mirror(s)</title>
<para>
Two kinds of mirrors exist: pre-mirrors and regular mirrors.
The <link linkend='var-PREMIRRORS'><filename>PREMIRRORS</filename></link>
and
<link linkend='var-MIRRORS'><filename>MIRRORS</filename></link>
variables point to these, respectively.
BitBake checks pre-mirrors before looking upstream for any
source files.
Pre-mirrors are appropriate when you have a shared directory
that is not a directory defined by the
<link linkend='var-DL_DIR'><filename>DL_DIR</filename></link>
variable.
A Pre-mirror typically points to a shared directory that is
local to your organization.
</para>
<para>
Regular mirrors can be any site across the Internet that is
used as an alternative location for source code should the
primary site not be functioning for some reason or another.
</para>
</section>
</section>
<section id="package-feeds-dev-environment">
<title>Package Feeds</title>
<para>
When the OpenEmbedded build system generates an image or an SDK,
it gets the packages from a package feed area located in the
<link linkend='build-directory'>Build Directory</link>.
The
<link linkend='general-yocto-environment-figure'>general Yocto Project Development Environment figure</link>
shows this package feeds area in the upper-right corner.
</para>
<para>
This section looks a little closer into the package feeds area used
by the build system.
Here is a more detailed look at the area:
<imagedata fileref="figures/package-feeds.png" align="center" width="7in" depth="6in" />
</para>
<para>
Package feeds are an intermediary step in the build process.
The OpenEmbedded build system provides classes to generate
different package types, and you specify which classes to enable
through the
<link linkend='var-PACKAGE_CLASSES'><filename>PACKAGE_CLASSES</filename></link>
variable.
Before placing the packages into package feeds,
the build process validates them with generated output quality
assurance checks through the
<link linkend='ref-classes-insane'><filename>insane</filename></link>
class.
</para>
<para>
The package feed area resides in the Build Directory.
The directory the build system uses to temporarily store packages
is determined by a combination of variables and the particular
package manager in use.
See the "Package Feeds" box in the illustration and note the
information to the right of that area.
In particular, the following defines where package files are
kept:
<itemizedlist>
<listitem><para><link linkend='var-DEPLOY_DIR'><filename>DEPLOY_DIR</filename></link>:
Defined as <filename>tmp/deploy</filename> in the Build
Directory.
</para></listitem>
<listitem><para><filename>DEPLOY_DIR_*</filename>:
Depending on the package manager used, the package type
sub-folder.
Given RPM, IPK, or DEB packaging and tarball creation, the
<link linkend='var-DEPLOY_DIR_RPM'><filename>DEPLOY_DIR_RPM</filename></link>,
<link linkend='var-DEPLOY_DIR_IPK'><filename>DEPLOY_DIR_IPK</filename></link>,
<link linkend='var-DEPLOY_DIR_DEB'><filename>DEPLOY_DIR_DEB</filename></link>,
or
<link linkend='var-DEPLOY_DIR_TAR'><filename>DEPLOY_DIR_TAR</filename></link>,
variables are used, respectively.
</para></listitem>
<listitem><para><link linkend='var-PACKAGE_ARCH'><filename>PACKAGE_ARCH</filename></link>:

# [NET] smc91x: fix PXA DMA support code
#
# The PXA DMA support code for smc91x doesn't pass a struct device to
# the dma_*map_single() functions, which leads to an oops in the dma
# bounce code. We have a struct device which was used to probe the
# SMC chip. Use it.
#
# (This patch is slightly larger because it requires struct smc_local
# to move into the header file.)

# [ARM] 4560/1: pxa: move processor specific set_wake logic out of irq.c
#
# a function pxa_init_irq_set_wake() was introduced, so that
# processor specific code could install their own version
#
# code setting PFER and PRER registers within pxa_gpio_irq_type
# are removed, and the edge configuration is postponed to the
# (*set_wake) and copies the GRER and GFER register, which will
# always be set up correctly by pxa_gpio_irq_type()

# [ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variable
#
# This definition produces processor specific code in generic function
# pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x
# and pxa27x in a single zImage.
#
# As David Brownell suggests, make it a run-time variable and initialize
# at run-time according to the number of GPIOs on the processor. For now
# the initialization happens in pxa_init_irq_gpio(), since there is
# already a parameter for that, besides, this is and MUST be earlier
# than any subsequent calls to pxa_gpio_mode().
