Zephyr Library Configuration Options

Kconfig files describe build-time configuration options (called symbols in Kconfig-speak), how they’re grouped into menus and sub-menus, and dependencies between them that determine what configurations are valid.

Kconfig files appear throughout the directory tree. For example, subsys/power/Kconfig defines power-related options.

This documentation is generated automatically from the Kconfig files by the gen_kconfig_rest.py script. Click on symbols for more information.
