Each Yocto Project release introduces a new set of linux-yocto kernel recipes,
|
|
||||||
tracking the latest upstream developments and introducing newly supported
|
|
||||||
platforms. In addition to the new kernel recipes, the previous recipes are
|
|
||||||
refreshed and supported for at least one additional release. As they align,
|
|
||||||
these previous releases are updated to include the latest from the LTSI project.
|
|
||||||
Besides these recipes, a linux-yocto-dev recipe is available for working with
|
|
||||||
the very latest in upstream Linux kernel development as well as meta-data
|
|
||||||
development.
|
|
||||||
|
|
||||||
If you do not maintain your own kernel sources and need to make only minimal
|
|
||||||
changes to the sources, these 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.
|
|
||||||
|
|
||||||
If, instead, you have a very specific Linux kernel source tree and are unable to
|
|
||||||
align with one of the many official linux-yocto releases, an alternative
|
|
||||||
exists by which you can use the Yocto Project Linux kernel tools with your own
|
|
||||||
sources.
|
|
||||||
|
|
||||||
The sections that follow provide instructions for completing specific Linux
|
|
||||||
kernel development tasks. They assume familiarity with working with bitbake
|
|
||||||
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:
|
|
||||||
|
|
||||||
o Yocto Project Getting Started Guide
|
|
||||||
o Yocto Project Development Manual
|
|
||||||
- 4.3 Modifying Temporary Source Code
|
|
||||||
- 5.1 Understanding and Creating Layers
|
|
||||||
- 4.1.2 Modifying the Kernel
|
|
||||||
(This section should be retired, as well as 5.6, 5.7 - with this document
|
|
||||||
providing the necessary information)
|
|
||||||
|
|
||||||
Finally, while this document focuses on the manual creation of recipes, patches,
|
|
||||||
and configuration files, the Yocto Project BSP tools are available to automate
|
|
||||||
this process with existing content and work well to create the initial framework
|
|
||||||
and boilerplate code. For details, refer to the Yocto Project BSP Developer's
|
|
||||||
Guide.
