The level bitmask should be a hex number. Done this functionality by extending dynamic debug metadata with new level member and propagate it over all the users. Also introduce new dynamic_pr_debug_level and dynamic_dev_dbg_level macros to be used by the drivers. Cc: Jason Baron Cc: Chris Mason Cc: Josef Bacik Cc: David Sterba Cc: "Rafael J.

Enabling the particular level will be done by dynamic debug with levels. For example to enable debug messages with low level: echo 'module venus_dec level 0x01 +p' > debugfs/dynamic_debug/control If you want to enable all levels: echo 'module venus_dec level 0x07 +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.
