When, CONFIG_DYNAMIC_PRINTK_DEBUG, +is not set, debugging statements can still be enabled as before, often by +defining 'DEBUG' for the proper compilation unit. Thus, this patch set has no +affect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set. + +The infrastructure currently ties into all pr_debug() and dev_dbg() calls. That +is, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls +can be dynamically enabled/disabled on a per-module basis. + +Future plans include extending this functionality to subsystems, that define +their own debug levels and flags. + +Usage: + +Dynamic debugging is controlled by the debugfs file, +<debugfs>/dynamic_printk/modules. This file contains a list of the modules that +can be enabled. The format of the file is as follows: + + <module_name> <enabled=0/1> + . + . + . + + <module_name> : Name of the module in which the debug call resides + <enabled=0/1> : whether the messages are enabled or not + +For example: + + snd_hda_intel enabled=0 + fixup enabled=1 + driver enabled=0 + +Enable a module: + + $echo "set enabled=1 <module_name>" > dynamic_printk/modules + +Disable a module: + + $echo "set enabled=0 <module_name>" > dynamic_printk/modules + +Enable all modules: + + $echo "set enabled=1 all" > dynamic_printk/modules + +Disable all modules: + + $echo "set enabled=0 all" > dynamic_printk/modules + +Finally, passing "dynamic_printk" at the command line enables +debugging for all modules.
