Subject: [PATCH] Log macros unified in a common API
Introduces a header to concentrate logging macro definitions for all
reuse, change aims to provide all currently existing logging
every C file can replace it's compile-unit definitions by common code.
Later enhancements to log can now be performed in a single file.
* Optional printing of thread pointer
* Optional printing of colored messages
* Optional printing of a label to indicate logging level (info, error,
* Caller function name printing
* Incremental log levels
* One point log disable
that all drivers can use. Currently we have a *bunch* of different
versions of the same thing in use throughout the driver tree.
I don't like the naming, we already have a kernel event logging API
people may assume that the two facilities are connected based on the name.
Can we change the names to debug_* or something else?
Again, do we want to take over _another_ namespace ? Maybe it should be
sys_debug or sys_dbg or sys_dbg_log ?
The sample implementation is adding all these in logging.h, which is a
public API file:
DBG, ERR, INF, WRN, THREAD_FN_CALL, IS_LOGGING_ACTIVE
which are very generic names. Don't forget that the application writer
is operating in the same C namespace, and we have been trying to keep
the namespaces the kernel owns to a minimum to minimize the number or
