I think the Kconfig option is pretty poor too but a
long needed extension to dev_dbg is to enable classes
of messages by level or mask.
There are many existing macros like
#define module_dbg(level, fmt, ...)
do {
if (level >= some_module_var)
debug_something(...);
} while (0)
and
#define module_dbg(mask, fmt, ...)
do {
if (mask & some_module_var)
debug_something(...)
} while (0)
It'd be nice to consolidate those in dev_dbg
I'll get 'round to it one day if Jason doesn't.
