Dear Yocto specialists
I have one question.
When building the kernel module and install to rootfs with Yocto, I got the kernel module without debug information.
Investigating a little bit revealed that it seems do_package process remove the debug information from binary,
as the file size indicates as shown below.

I would like to kept debug information preserved.
I've check the manual but could not find out how to control this behavior.
Does anyone know how to do that ?
Any information is highly appreciated.
Kind Regars,
John Rama
