+<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>Introduction</title>
+ <title>Introducing the Application Development Toolkit (ADT)</title>
<para>
- The Yocto Project presents the kernel as a fully patched, history-clean git
- repository.
- The git tree represents the selected features, board support,
- and configurations extensively tested by Yocto Project.
- The Yocto Project kernel allows the end user to leverage community
- best practices to seamlessly manage the development, build and debug cycles.
+ 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>
- This manual describes the Yocto Project kernel by providing information
- on its history, organization, benefits, and use.
- The manual consists of two sections:
- <itemizedlist>
- <listitem><para>Concepts - Describes concepts behind the kernel.
- You will understand how the kernel is organized and why it is organized in
- the way it is. You will understand the benefits of the kernel's organization
- and the mechanisms used to work with the kernel and how to apply it in your
- design process.</para></listitem>
- <listitem><para>Using the Kernel - Describes best practices and "how-to" information
- that lets you put the kernel to practical use. Some examples are "How to Build a
- Project Specific Tree", "How to Examine Changes in a Branch", and "Saving Kernel
- Modifications."</para></listitem>
- </itemizedlist>
+ 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>

+ 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.

+ <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>
+ <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.
