do. - </para></listitem> - <listitem><para>Does the manual note that Yocto Project delivers - a key set of supported kernel types, where - each type is tailored to meet a specific use (e.g. networking, - consumer, devices, and so forth).</para></listitem> - <listitem><para>Do we convey that the Yocto Project uses a - Git branching strategy that, from a - developer's point of view, results in a linear path from the - baseline kernel.org, through a select group of features and - ends with their BSP-specific commits.</para></listitem> - </itemizedlist> -</para> ---> - - <section id='kernel-dev-overview'> - <title>Overview</title> - - <para> - Regardless of how you intend to make use of the Yocto Project, - chances are you will work with the Linux kernel. - This manual provides background information on the Yocto Linux kernel - <ulink url='&YOCTO_DOCS_DEV_URL;#metadata'>Metadata</ulink>, - describes common tasks you can perform using the kernel tools, - and shows you how to use the kernel Metadata needed to work with - the kernel inside the Yocto Project. - </para> - - <para> - Each Yocto Project release has a set of linux-yocto recipes, whose - Git repositories you can view in the Yocto - <ulink url='&YOCTO_GIT_URL;'>Source Repositories</ulink> under - the "Yocto Linux Kernel" heading. - New recipes for the release track the latest upstream developments - and introduce newly-supported platforms. - Previous recipes in the release are refreshed and supported for at - least one additional release. - As they align, these previous releases are updated to include the - latest from the - <ulink url='&YOCTO_HOME_URL;/organization/long-term-support-initiative-ltsi'>Long Term Support Initiative</ulink> - (LTSI) project. - Also included is a linux-yocto development recipe - (<filename>linux-yocto-dev.bb</filename>) should you want to work - with the very latest in upstream Linux kernel development and - kernel Metadata development. - </para> - - <para> - The Yocto Project also provides a powerful set of kernel - tools for managing Linux kernel sources and configuration data. - You can use these tools to make a single configuration change, - apply multiple patches, or work with your own kernel sources. - </para> - - <para> - In particular, the kernel tools allow you to generate configuration - fragments that specify only what you must, and nothing more. - Configuration fragments only need to contain the highest level - visible <filename>CONFIG</filename> options as presented by the Linux - kernel <filename>menuconfig</filename> system. - Contrast this against a complete Linux kernel - <filename>.config</filename>, which includes all the automatically - selected <filename>CONFIG</filename> options. - This efficiency reduces your maintenance effort and allows you - to further separate your configuration in ways that make sense for - your project. - A common split separates policy and hardware. - For example, all your kernels might support - the <filename>proc</filename> and <filename>sys</filename> filesystems, - but only specific boards require sound, USB, or specific drivers. - Specifying these configurations individually allows you to aggregate - them together as needed, but maintains them in only one place. - Similar logic applies to separating source changes. - </para> - - <para> - If you do not maintain your own kernel sources and need to make - only minimal changes to the sources, the released recipes provide a - vetted base upon which to layer your changes. - Doing so allows you to benefit from the continual kernel - integration and testing performed during development of the - Yocto Project. - </para> - - <para> - If, instead, you have a very specific Linux kernel source tree - and are unable to align with one of the official linux-yocto - recipes, an alternative exists by which you can use the Yocto - Project Linux kernel tools with your own kernel sources. - </para> - </section> - - <section id='kernel-dev-other-resources'> - <title>Other Resources</title> - - <para> - The sections that follow provide instructions for completing - specific Linux kernel development tasks. - These instructions assume you are comfortable working with - <ulink url='http://openembedded.org/wiki/Bitbake'>BitBake</ulink> - recipes and basic open-source development tools. - Understanding these concepts will facilitate the process of working - with the kernel recipes. - If you find you need some additional background, please be sure to - review and understand the following documentation: -
