Subject: Kconfig in external modules
Date: Thu, 22 Feb 2018 10:06:43 -0300	[thread overview]
Message-ID: <20180222130643.GA7819@gmail.com> (raw)

Hi all,

The kbuild documentation states that is possible to use CONFIG_ options in
external (out-of-tree) modules. However, is it possible for an external module
to define new options in a local Kconfig file?

For example, I would have 2 files

    /path/to/module/Kconfig
    /path/to/module/.config

when I run the usual command to build external module

    $ make -C /lib/modules/`uname -r`/build M=/path/to/module modules

the options present in the local .config file would be exported by kbuild as C
#define's and make variables to be used in the module. The build system supports
such feature?

Thanks,
~ Gustavo
