If you are going to be modifying kernel recipes, it is recommended
that you create and prepare your own layer in which to do your
work.
Your layer contains its own BitBake append files
(.bbappend
) and provides a convenient
mechanism to create your own recipe files
(.bb
).
For details on how to create and work with layers, see the following
sections in the Yocto Project Development Manual:
"Understanding and Creating Layers" for general information on layers and how to create layers.
"Set Up Your Layer for the Build" for specific instructions on setting up a layer for kernel development.
