|

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.

|

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().

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.

used for the most common log messages.

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.
