Dear all,

I have the following problem. Some functionality can be either built into the kernel or it can be build as a module. In the latter case the application should load the module.

Is there a general approach to test if specific functionality is built statically or as a module?

If available, you can check .config file. (e.g check if CONFIG_X_OPTION=Y or CONFIG_X_OPTION=m).

If you don't have your .config (distro prebuilt image), you can check /proc/config.gz or /boot/ for a config which corresponds to your uname -r. Vlad
