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.

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().

config LOG_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.
