| 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. |

| 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. |

| 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(). |
