installing kernel modules in root filesystem

installing kernel modules in root filesystem

[Richard Cagley]

I have a kernel module that shows up in my build work directory after
I configure the kernel accordingly
build/tmp-glibc/work/zedboard_zynq7-oe-linux-gnueabi/linux-xlnx/3.14-xilinx+gitAUTOINC+2b48a8aeea-r0/image/lib/modules/3.14.2-xilinx/kernel/drivers/dma/xilinx/vdmatest.ko

But, when I add "kernel-modules" to my IMAGE_INSTALL in local.conf I
don't see vdmatest.ko show up in the resultant root filesystem after I
run bitbake core-image-minimal-dev and untar the image

Is there a way to tell yocto to install all kernel modules or a step
I've missed?

I have:

MACHINE_EXTRA_RRECOMMENDS = "kernel-modules"

in my machine conf,

Make sure you have buildhistory in your user classes. That creates files
that are very helpful for working out what is actually in the generated
packages.

Wow, thanks. I spent a lot of time trying to figure out that one. I
stuck it in local.conf for now but I guess the machine.conf would
eventually make more sense.

thanks for the tip. I just turned this on and will try to leverage it
in the future.
