	  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.

	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.

	  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().
