Building Linux Kernel Module Package

[actionmystique]

Hello everyone,

I'm trying to build a debian package for all new Realtek WiFi drivers based on Linux kernel 4.3.0 (https://github.com/torvalds/linux) and release it to the public so they can install them on Ubuntu 15.10 (linux 4.2.0-16). The latest backported drivers (http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/) are already old (4.2.0).

So far, I've been able to install the kernel module from the Linus Torvald github sources with:


make oldconfig
make prepare
make modules_prepare
make modules SUBDIRS=scripts
make modules SUBDIRS=scripts/mod
make modules SUBDIRS=drivers/net/wireless/rtlwifi
make modules_install SUBDIRS=drivers/net/wireless/rtlwifi

This installs the drivers inside /lib/modules/4.3.0+

The directory tree is different on current /lib/modules/4.2.0-16-generic:

I'm stuck here. I don't know how to build the package with checkinstall so that the drivers are used with the current linux kernel.
Also, it seems that some files are missing in my build folder & I don't know how to generate them:


modules.order
Module.symvers
...

Your assistance would be greatly appreciated.

P.S: all the Ubuntu packages that I have built & released so far are available here (https://github.com/jean-christophe-manciot).
