-<title>Application Development Toolkit (ADT) User's Guide</title>
-
-<para>
- Welcome to the Application Development Toolkit User’s Guide. This manual provides
- information that lets you get going with the ADT to develop projects using the Yocto
- Project.
-</para>

-<section id='book-intro'>
- <title>Introducing the Application Development Toolkit (ADT)</title>
- <para>
- Fundamentally, the ADT consists of an architecture-specific cross-toolchain and
- a matching sysroot that are both built by the Poky build system.
- The toolchain and sysroot are based on a metadata configuration and extensions,
- which allows you to cross develop for the target on the host machine.
- </para>
- <para>
- Additionally, to provide an effective development platform, the Yocto Project
- makes available and suggests other tools as part of the ADT.
- These other tools include the Eclipse IDE Yocto Plug-in, an emulator (QEMU),
- and various user-space tools that greatly enhance your development experience.
- </para>
- <para>
- The resulting combination of the architecture-specific cross-toolchain and sysroot
- along with these additional tools yields a custom-built, cross-development platform
- for a user-targeted product.
- </para>
-
- <section id='the-cross-toolchain'>
- <title>The Cross-Toolchain</title>
- <para>
- The cross-toolchain consists of a cross-compiler, cross-linker, and cross-debugger
- that are all generated through a Poky build 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
- Poky and uses the same metadata configuration used to build the cross-toolchain.
- </para>
- </section>
-
- <section id='the-qemu-emulator'>
- <title>The QEMU Emulator</title>
- <para>
- The QEMU emulator allows you to simulate your hardware while running your
- application or image.
- QEMU is installed several ways: as part of the Poky tree, ADT installation
- through a toolchain tarball, or through the ADT Installer.
- </para>

- <section id='user-space-tools'>
- <title>User-Space Tools</title>
- <para>
- User-space tools are included as part of the distribution.
- 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.
- You can find out more about LatencyTOP at
- <ulink url='http://www.latencytop.org/'></ulink>.
- </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='http://www.linuxpowertop.org/'></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>.
- </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/index.php'></ulink> and click
- on “Perf tools.”
- </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 Yocto Eclipse IDE Plug-in.
- See <ulink url='http://sourceware.org/systemtap'></ulink> for more information
- on SystemTap.
- </para></listitem>
- <listitem><para><emphasis>Lttng-ust</emphasis> – A User-space Tracer designed to
- provide detailed information on user-space activity.
- See <ulink url='http://lttng.org/ust'></ulink> for more information on Lttng-ust.
