Defines the kernel type to be used in assembling the
configuration.
The linux-yocto recipes define "standard", "tiny", and
"preempt-rt" kernel types.
See the

section in the Yocto Project Linux Kernel Development
Manual for more information on kernel types.

<para>
If you do not specify a
<filename>LINUX_KERNEL_TYPE</filename>, it defaults to
"standard".
Together with
<link linkend='var-KMACHINE'><filename>KMACHINE</filename></link>,
the <filename>LINUX_KERNEL_TYPE</filename> variable
defines the search
arguments used by the kernel tools to find the appropriate
description within the kernel Metadata with which to build
out the sources and configuration.

For example, the linux-yocto kernel recipes all define
the variable as follows:
<literallayout class='monospaced'>
LINUX_VERSION_EXTENSION ?= "-yocto-${LINUX_KERNEL_TYPE}"
LINUX_VERSION_EXTENSION ?= "-yocto-${<link linkend='var-LINUX_KERNEL_TYPE'>LINUX_KERNEL_TYPE</link>}"
</literallayout>
Defining this variable essentially sets the
Linux kernel configuration item
