Enabling the particular level will be done by dynamic debug. For example to enable debug messages with low level: echo 'format "VENUSL" +p' > debugfs/dynamic_debug/control If you want to enable all levels: echo 'format "VENUS" +p' > debugfs/dynamic_debug/control All the features which dynamic debugging provide are preserved. And finaly all dev_dbg are translated to VDBGX with appropriate debug levels.
