- Log messages are buffered and processed later. This mode has the

- deferred to the known context.

- 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().
- config LOG_FRONTEND
- bool "Frontend"
- help
- When enabled, logs are redirected to a custom frontend instead
- of being processed by the logger. In this mode runtime filtering and
- multiple backends are not used.
