External Linux Kernel Module

External Linux Kernel Module

Hello,

I'm working on incorporating an external kernel module based on the hello-mod skeleton recipe. Everything was going well until I added the following line to my machine configuration:

MACHINE_EXTRA_RDEPENDS += "kernel-module-hello"

Attempting to run "bitbake core-image-base" then leads to the following error:

no package provides kernel-module-hello

After digging through the .bbclass files in the meta folder, I'm beginning to think that the following comment in the hello-mod_0.1.bb file is no longer true:

# The inherit of module.bbclass will automatically name module packages with
# "kernel-module-" prefix as required by the oe-core build environment.

Adding the following lines to the end of hello-mod_0.1.bb allows the image to be successfully created:

PROVIDES = "kernel-module-hello"
RPROVIDES_${PN} = "kernel-module-hello"

Has something been changed in module.bbclass? Is it even required to have to have the "kernel-module-" prefix?

Thanks,

Thomas

I think that comment is outdated or something that someone wanted to implement 
some day or so.

I've always just named my kernel module recipes "kernel-module-XXX.bb".
