config JSON_LIBRARY |
|
bool "Build JSON library" |
|
help |
|
Build a minimal JSON parsing/encoding library. Used by sample |
|
applications such as the NATS client. |
|

select REQUIRES_FULL_LIBC |
|
help |
|
Build the JSON library with support for floating point types. |
|
|
|
Requires a libc implementation with support for floating point |
|
functions: strtof(), strtod(), isnan() and isinf(). |

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. |

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. |

bool "UTF-8 string operation supported" |
|
help |

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