| help |
| Log messages are buffered and processed later. This mode has the |
| least impact on the application. Time consuming processing is |
| deferred to the known context. |
| |
| config LOG_MODE_IMMEDIATE |
| bool "Synchronous" |
| help |
| When enabled log is processed in the context of the call. It impacts |
| performance of the system since time consuming operations are |
| performed in the context of the log entry (e.g. high priority |
| interrupt).Logger backends must support exclusive access to work |
| flawlessly in that mode because one log operation can be interrupted |
| by another one in the higher priority context. |

| bool "Minimal-footprint" |
| select PRINTK |
| help |
| Enable minimal logging implementation. This has very little footprint |
| overhead on top of the printk() implementation for standard |
| logging macros. Hexdump macros are also supported, with a small |
| amount of code pulled in if used. Build time filtering is supported, |
| but not runtime filtering. There are no timestamps, prefixes, |
| colors, or asynchronous logging, and all messages are simply |
| sent to printk(). |

| config LOG_FRONTEND |
| bool "Frontend" |
| help |
| When enabled, logs are redirected to a custom frontend which is the |
| fastest way of getting logs out. The logs are redirected at the function |
| level. To redirect logs at the macro level, see LOG_CUSTOM_HEADER. |

| config LOG_FRONTEND_ONLY |

| help |
| Option indicates that there are no backends intended to be used. |
| Code asserts if any backend is enabled. |

| config LOG_CUSTOM_HEADER |
| bool "Include Custom Log Header" |
| help |
| When enabled, a custom application provided header, named |
| "zephyr_custom_log.h", is included at the end of log.h. This enables |
| extension of the LOG_* APIs at the macro level. Please use cautiously! |
| The internal LOG API may change in future releases. |
