+ <title>The Application Development Toolkit (ADT)</title>
+
+ <para>
+ Part of the Yocto Project development solution is an Application Development
+ Toolkit (ADT).
+ The ADT provides you with a custom-built, cross-development
+ platform suited for developing a user-targeted product application.
+ </para>
+
+ <para>
+ Fundamentally, the ADT consists of the following:
+ <itemizedlist>
+ <listitem><para>An architecture-specific cross-toolchain and matching
+ sysroot both built by the
+ <ulink url='&YOCTO_DOCS_DEV_URL;#build-system-term'>OpenEmbedded build system</ulink>.
+ The toolchain and sysroot are based on a
+ <ulink url='&YOCTO_DOCS_DEV_URL;#metadata'>Metadata</ulink>
+ configuration and extensions,
+ which allows you to cross-develop on the host machine for the target hardware.
+ </para></listitem>
+ <listitem><para>The Eclipse IDE Yocto Plug-in.</para></listitem>
+ <listitem><para>The Quick EMUlator (QEMU), which lets you simulate target hardware.
+ </para></listitem>
+ <listitem><para>Various user-space tools that greatly enhance your application
+ development experience.</para></listitem>
+ </itemizedlist>
+ </para>
+
+ <section id='the-cross-development-toolchain'>
+ <title>The Cross-Development Toolchain</title>
+
+ <para>
+ The
+ <ulink url='&YOCTO_DOCS_DEV_URL;#cross-development-toolchain'>Cross-Development Toolchain</ulink>
+ consists of a cross-compiler, cross-linker, and cross-debugger
+ that are used to develop user-space applications for targeted
+ hardware.
+ This toolchain is created either by running the ADT Installer
+ script, a toolchain installer script, or through a
+ <ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink>
+ that is based on your Metadata configuration or extension for
+ your targeted device.
+ The cross-toolchain works with a matching target sysroot.
+ </para>
+ </section>
+
+ <section id='sysroot'>
+ <title>Sysroot</title>
+
+ <para>
+ The matching target sysroot contains needed headers and libraries for generating
+ binaries that run on the target architecture.
+ The sysroot is based on the target root filesystem image that is built by
+ the OpenEmbedded build system and uses the same Metadata configuration
+ used to build the cross-toolchain.
+ </para>
+ </section>

+ <section id='eclipse-overview'>
+ <title>Eclipse Yocto Plug-in</title>
+
+ <para>
+ The Eclipse IDE is a popular development environment and it fully supports
+ development using the Yocto Project.
+ When you install and configure the Eclipse Yocto Project Plug-in into
+ the Eclipse IDE, you maximize your Yocto Project experience.
+ Installing and configuring the Plug-in results in an environment that
+ has extensions specifically designed to let you more easily develop software.
+ These extensions allow for cross-compilation, deployment, and execution of
+ your output into a QEMU emulation session.
+ You can also perform cross-debugging and profiling.
+ The environment also supports a suite of tools that allows you to perform
+ remote profiling, tracing, collection of power data, collection of
+ latency data, and collection of performance data.
+ </para>
+
+ <para>
+ For information about the application development workflow that uses the Eclipse
+ IDE and for a detailed example of how to install and configure the Eclipse
+ Yocto Project Plug-in, see the
+ "<ulink url='&YOCTO_DOCS_DEV_URL;#adt-eclipse'>Working Within Eclipse</ulink>" section
+ of the Yocto Project Development Manual.

+ <title>The QEMU Emulator</title>
+
+ <para>
+ The QEMU emulator allows you to simulate your hardware while running your
+ application or image.
+ QEMU is made available a number of ways:
+ <itemizedlist>
+ <listitem><para>
+ If you use the ADT Installer script to install ADT, you can
+ specify whether or not to install QEMU.
+ </para></listitem>

+ If you have cloned the <filename>poky</filename> Git

+ and you have sourced the environment setup script, QEMU is
+ installed and automatically available.
+ </para></listitem>
+ <listitem><para>
+ If you have downloaded a Yocto Project release and unpacked
+ it to create a

+ installed and automatically available.
+ </para></listitem>
+ <listitem><para>
+ If you have installed the cross-toolchain tarball and you

+ <section id='user-space-tools'>
+ <title>User-Space Tools</title>
+
+ <para>
+ User-space tools are included as part of the Yocto Project.
+ You will find these tools helpful during development.
+ The tools include LatencyTOP, PowerTOP, OProfile, Perf, SystemTap, and Lttng-ust.
+ These tools are common development tools for the Linux platform.
+ <itemizedlist>
+ <listitem><para><emphasis>LatencyTOP:</emphasis> LatencyTOP focuses on latency
+ that causes skips in audio,
+ stutters in your desktop experience, or situations that overload your server
+ even when you have plenty of CPU power left.
+ </para></listitem>
+ <listitem><para><emphasis>PowerTOP:</emphasis> Helps you determine what
+ software is using the most power.
+ You can find out more about PowerTOP at
+ <ulink url='https://01.org/powertop/'></ulink>.</para></listitem>
+ <listitem><para><emphasis>OProfile:</emphasis> A system-wide profiler for Linux
+ systems that is capable of profiling all running code at low overhead.
+ You can find out more about OProfile at
+ <ulink url='http://oprofile.sourceforge.net/about/'></ulink>.
+ For examples on how to setup and use this tool, see the
+ "<ulink url='&YOCTO_DOCS_PROF_URL;#profile-manual-oprofile'>OProfile</ulink>"
+ section in the Yocto Project Profiling and Tracing Manual.
+ </para></listitem>
+ <listitem><para><emphasis>Perf:</emphasis> Performance counters for Linux used
+ to keep track of certain types of hardware and software events.
+ For more information on these types of counters see
+ <ulink url='https://perf.wiki.kernel.org/'></ulink>.
+ For examples on how to setup and use this tool, see the
+ "<ulink url='&YOCTO_DOCS_PROF_URL;#profile-manual-perf'>perf</ulink>"
+ section in the Yocto Project Profiling and Tracing Manual.
+ </para></listitem>
+ <listitem><para><emphasis>SystemTap:</emphasis> A free software infrastructure
+ that simplifies information gathering about a running Linux system.
+ This information helps you diagnose performance or functional problems.
+ SystemTap is not available as a user-space tool through the Eclipse IDE Yocto Plug-in.
+ See <ulink url='http://sourceware.org/systemtap'></ulink> for more information
+ on SystemTap.
+ For examples on how to setup and use this tool, see the
