This class handles building Linux kernels.
|
|||
|
|
The class contains code to build all kernel trees.
|
|||
|
|
All needed headers are staged into the
|
|||
|
|
<code class="filename"><a class="link" href="ref-variables-glos.html#var-STAGING_KERNEL_DIR" title="STAGING_KERNEL_DIR">STAGING_KERNEL_DIR</a></code>
|
|||
|
|
directory to allow out-of-tree module builds using <code class="filename">module.bbclass</code>.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
This means that each built kernel module is packaged separately and inter-module
|
|||
|
|
dependencies are created by parsing the <code class="filename">modinfo</code> output.
|
|||
|
|
If all modules are required, then installing the <code class="filename">kernel-modules</code>
|
|||
|
|
package installs all packages with modules and various other kernel packages
|
|||
|
|
such as <code class="filename">kernel-vmlinux</code>.
|
|||
|
|
</p>
|
|||
|
|
<p>
|
|||
|
|
Various other classes are used by the kernel and module classes internally including
|
|||
|
|
<code class="filename">kernel-arch.bbclass</code>, <code class="filename">module_strip.bbclass</code>,
|
|||
|
|
<code class="filename">module-base.bbclass</code>, and <code class="filename">linux-kernel-base.bbclass</code>.
