Kconfig in external modules

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
