Hello Simon,
I would like to convert printf and debug messages in the UEFI sub-system to log messages.
Currently if CONFIG_LOG=n, log_*() functions are mapped to log_nop(). So no output is provided independent of the criticality of the message.
What I would like to do is map log_err() to printf() and log_debug() to debug() if CONFIG_LOG=n . This way we could get the same console output no matter if CONFIG_LOG is enabled.
Would this make sense to you?
#if CONFIG_IS_ENABLED(LOG) #define _LOG_MAX_LEVEL CONFIG_VAL(LOG_MAX_LEVEL) #define log_err(_fmt...) log(LOG_CATEGORY, LOGL_ERR, ##_fmt) #define log_warning(_fmt...) log(LOG_CATEGORY, LOGL_WARNING, ##_fmt) #define log_notice(_fmt...) log(LOG_CATEGORY, LOGL_NOTICE, ##_fmt) #define log_info(_fmt...) log(LOG_CATEGORY, LOGL_INFO, ##_fmt) #define log_debug(_fmt...) log(LOG_CATEGORY, LOGL_DEBUG, ##_fmt) #define log_content(_fmt...) log(LOG_CATEGORY, LOGL_DEBUG_CONTENT, ##_fmt) #define log_io(_fmt...) log(LOG_CATEGORY, LOGL_DEBUG_IO, ##_fmt) #else #define _LOG_MAX_LEVEL LOGL_INFO #define log_err(_fmt...) printf(##_fmt) #define log_warning(_fmt...) printf(##_fmt) #define log_notice(_fmt...) printf(##_fmt) #define log_info(_fmt...) printf(##_fmt) #define log_debug(_fmt...) debug(##_fmt) #define log_content(_fmt...) log_nop(LOG_CATEGORY, \ LOGL_DEBUG_CONTENT, ##_fmt) #define log_io(_fmt...) log_nop(LOG_CATEGORY, LOGL_DEBUG_IO, ##_fmt) #endif
Best regards
