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. config LOG_MODE_IMMEDIATE bool "Synchronous" select MPSC_PBUF help When enabled log is processed in the context of the call.

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. endchoice config LOG2 bool config LOG_IMMEDIATE bool default y if LOG_MODE_IMMEDIATE default y if LOG2_MODE_IMMEDIATE config LOG_MINIMAL bool imply PRINTK default y if LOG_MODE_MINIMAL
