| 10 | <para> | 16 | <para> |
| 11 | The Yocto Project presents the kernel as a fully patched, history-clean git | 17 | Fundamentally, the ADT consists of an architecture-specific cross-toolchain and |
| 12 | repository. | 18 | a matching sysroot that are both built by the Poky build system. |
| 13 | The git tree represents the selected features, board support, | 19 | The toolchain and sysroot are based on a metadata configuration and extensions, |
| 14 | and configurations extensively tested by Yocto Project. | 20 | which allows you to cross develop for the target on the host machine. |
| 15 | The Yocto Project kernel allows the end user to leverage community | ||
| 16 | best practices to seamlessly manage the development, build and debug cycles. | ||

| 19 | This manual describes the Yocto Project kernel by providing information | 23 | Additionally, to provide an effective development platform, the Yocto Project |
| 20 | on its history, organization, benefits, and use. | 24 | makes available and suggests other tools as part of the ADT. |
| 21 | The manual consists of two sections: | 25 | These other tools include the Eclipse IDE Yocto Plug-in, an emulator (QEMU), |
| 22 | <itemizedlist> | 26 | and various user-space tools that greatly enhance your development experience. |
| 23 | <listitem><para>Concepts - Describes concepts behind the kernel. | ||
| 24 | You will understand how the kernel is organized and why it is organized in | ||
| 25 | the way it is. You will understand the benefits of the kernel's organization | ||
| 26 | and the mechanisms used to work with the kernel and how to apply it in your | ||
| 27 | design process.</para></listitem> | ||
| 28 | <listitem><para>Using the Kernel - Describes best practices and "how-to" information | ||
| 29 | that lets you put the kernel to practical use. Some examples are "How to Build a | ||
| 30 | Project Specific Tree", "How to Examine Changes in a Branch", and "Saving Kernel | ||
| 31 | Modifications."</para></listitem> | ||

| 48 | 35 | <title>The Cross-Toolchain</title> | |
| 49 | 36 | <para> | |
| 37 | The cross-toolchain consists of a cross-compiler, cross-linker, and cross-debugger | ||
| 38 | that are all generated through a Poky build that is based on your metadata | ||
| 39 | configuration or extension for your targeted device. | ||
| 40 | The cross-toolchain works with a matching target sysroot. | ||

| 44 | <section id='sysroot'> | ||
| 45 | <title>Sysroot</title> | ||
| 46 | <para> | ||
| 47 | The matching target sysroot contains needed headers and libraries for generating | ||
| 48 | binaries that run on the target architecture. | ||
| 49 | The sysroot is based on the target root filesystem image that is built by | ||
| 50 | Poky and uses the same metadata configuration used to build the cross-toolchain. | ||

| 56 | <para> | ||
| 57 | The QEMU emulator allows you to simulate your hardware while running your | ||
| 58 | application or image. | ||
| 59 | QEMU is installed several ways: as part of the Poky tree, ADT installation | ||
| 60 | through a toolchain tarball, or through the ADT Installer. | ||
