Hi,
I am not sure if this is the problem you are struggling with.
I am wondering why class module.bbclass behaves completely different
than kernel.bbclacc
hi, I follow the kernel development manual "2.5. Incorporating
Out-of-Tree Modules",
copy the "hello-mod_0.1.bb" and "files" folder into my taget layer
"meta-intel/meta-jasperforest/recipe-kernel", then add
"MACHINE_EXTRA_
RDEPENDS += "kernel-module-hello" in the conf/local.conf
after build and boot, there's no "hello.ko" found in the binary
image
also there's no hello.ko in the "tmp/work/..." folder
If you hello-mod_0.1.bb inherits module class there is no mechanism
to create the kernel-module package. This only applies to the
kernel.bbclass
http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/classes/module.bbclass
http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/classes/module-base.bbclass
Have a look at kernel.bbclass instead shows some pathon code which
handles the module package creation:
http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/classes/kernel.bbclass#n301
I've fixed this in my layer by stealing the code from kernel.bbclass
https://github.com/project-magpie/meta-stlinux/blob/master/recipes-bsp/tdt-driver/tdt-driver.inc
With this you can also use the following extends with your module:
module_autoload_aotom = "aotom"
and
module_conf_stmfb = "options stmfb
display0=1280x720-32@50:8m:pal:yuv:yuv"
If you are only inherting from module this have not worked for me.
The next part I had to fight against was the fact that in
core-image-minimal the package managment information are stripped and
thus no pre hooks are executet. So the module is installed in the image
but not loaded on boot-up unless you call update-modules by hand.
ROOTFS_POSTPROCESS_COMMAND += "remove_packaging_data_files ; "
To prevent this I've defined an image without the stripping:
https://github.com/project-magpie/meta-stlinux/blob/master/recipes-core/images/core-image-base.bb
I hope this clarify things a little bit

All,
There is a new YP manual under development. It is a development
manual
for Linux kernels in the YP. Darren Hart is the original author of
the
manual as you probably know. It is still being worked on but it is in
HTML form and now part of the yocto-docs/master branch. It is
published at
http://www.yoctoproject.org/docs/1.4/kernel-dev/kernel-dev.html [1].
Feel free to access it and comment.
Thanks,
Scott

Hi,
I am reposting this to the discussion list and copying Darren Hart.
