I could not find a way to patch the kernel source before its is built.
I promise to update the Yocto wiki's How do I section when I have a
working solution for the following :-)
This should be covered in the existing documentation and also the
more general bitbake/oe-core docs.
Here is what I am trying to do:
1) Patch the kernel (add VID/PID to hid_ignore_list in
drivers/hid/hid-core.c and also to add the VID/PID to .h file)
2) Build the kernel - no change here - standard kernel build
3) Build a kernel module
I have a meta layer where I am keeping my changes. I am guessing that I need to:
a) write a bbappend file to accomplish #1
b) write a recipe to accomplish #3
I have written recipes before, but just for libraries and autotools
based applications. Not for a kernel module. If there is a recipe out
there for some other module, I would be happy to steal from it.
Please advise how I can go about patching the kernel and if there is a
It's just like any other package. If your changes are simple, then
generating patches and putting them on the SRC_URI via a bbappend in
your layer is all you need. If you have complex changes, there are options
to manage them via git or via feature descriptions.
recipe for a kernel module - please point me to it.
Darren validated and updated the kernel module example, so he'd probably
got this closer at hand than I do.
