Explaining Yocto's Linux kernel support

The Yocto project offers a kernel framework that allows us to work with the Linux kernel in different ways:

• Fetching the source from a Git repository and applying patches to it. This is the path taken by the Freescale community BSP-supported kernels, as we saw previously.
• The linux-yocto style kernels that generate the kernel source from a set of Git branches and leafs. Specific features are developed in branches, and a leaf is followed for a complete set of features.

In this recipe, we will show how to work with a linux-yocto style kernel.

How to do it...

To use a linux-yocto style kernel, the kernel recipe inherits the linux-yocto.inc file. A Git repository for a linux-yocto style kernel contains metadata either ...
