| config JSON_LIBRARY |
| bool "Build JSON library" |
| help |
| Build a minimal JSON parsing/encoding library. Used by sample |
| applications such as the NATS client. |
| |
| config RING_BUFFER |
| bool "Ring buffers" |
| help |
| Provide highly efficient ring buffer management for arbitrary data. |
| Some facilities such as kernel pipes are built on top of this. |
| May be used directly e.g. when the pipe overhead is unnecessary. |
| |
| config RING_BUFFER_LARGE |
| bool "Allow large ring buffer sizes" |
| depends on RING_BUFFER |
| help |
| Increase maximum buffer size from 32KB to 2GB. When this is enabled, |
| all struct ring_buf instances become 12 bytes bigger. |

| config NOTIFY |
| bool "Asynchronous Notifications" |
| help |
| Use this API to support async transactions. |

| config BASE64 |
| bool "Base64 encoding and decoding" |
| help |
| Enable base64 encoding and decoding functionality |

| bool "On-Off Manager" |
| select NOTIFY |
| help |
| An on-off manager supports an arbitrary number of clients of a |
| service which has a binary state. Example applications are power |
| rails, clocks, and binary device power management. |

| config WINSTREAM |
| bool "Lockless shared memory window byte stream" |
| help |
| Winstream is a byte stream IPC for use in shared memory |
| "windows", generally for transmit to non-Zephyr contexts that |
| can't share Zephyr APIs or data structures. |

| config WINSTREAM_STDLIB_MEMCOPY |
| bool "Use standard memcpy() in winstream" |
| help |
| The sys_winstream utility is sometimes used in early boot |
| environments before the standard library is usable. By |
| default it uses a simple internal bytewise memcpy(). Set |
| this to use the one from the standard library. |

| config UTF8 |
| bool "UTF-8 string operation supported" |

| Enable the utf8 API. The API implements functions to specifically |
| handle UTF-8 encoded strings. |
