Hello,
I have an out of tree kernel module which I want autoloaded at startup
on my system. Looking at the Yocto project manual, I see that one way
I can do this is to add the module name to the KERNEL_MODULE_AUTOLOAD
variable within my custom module recipe.
What I have found is that the module-split class is indeed generating
the "/etc/modules-load.d/mymodule.conf" file, however this file is not
actually being installed. To be more precise it is appearing in the
"package" directory (i.e.
tmp/work/**/mymodule/package/etc/modules-load.d/mymodule.conf) but not
within the "image" directory (nor in my final rootfs).
Is there something I'm missing in the usage of KERNEL_MODULE_AUTOLOAD?
Is the intention for this variable I add extra steps to manually
install this file in my recipe? FYI I'm using Morty.
Can you provide your recipe ? It would make suggestions easier. For
example, my first question is: Is the module being installed to your
image via IMAGE_INSTALL, or some other similar variable ?
Bruce
Thanks,

Hi Bruce,
Thanks for your quick reply. Yes the module is being installed via
image_install. Module is installed but generated conf file is not. See
recipe below:
Hmm. If you are really installing kernel-module-<your name> to the
image, at a glance, what you have really should be enough.
Can you confirm that you are seeing your .ko on the image, and that
it just isn't being autoloaded ? Are you running an init system that
respects the autoload configuration ?
require mymodule.inc
inherit module kernel-module-split
Note that module already inherits kernel-module-split, so you really
shouldn't need to explicitly add that inherit.
