Typically, when using a <filename>defconfig</filename> to
configure a kernel during a build, you place the
file in your layer in the same manner as you would
patch files and configuration fragment files (i.e.
place patch files and configuration fragment files (i.e.
"out-of-tree").
However, if you want to use a <filename>defconfig</filename>
file that is part of the kernel tree (i.e. "in-tree"),
you can use the

file.
</para>

To use the variable, set it in the append file for your
kernel recipe using the following form:
<literallayout class='monospaced'>
KBUILD_DEFCONFIG_<link linkend='var-KMACHINE'>KMACHINE</link> ?= <replaceable>defconfig_file</replaceable>
KBUILD_DEFCONFIG_<replaceable>KMACHINE</replaceable> ?= <replaceable>defconfig_file</replaceable>
