+
+ Compiles debug level messages into the kernel, which would not
+ otherwise be available at runtime. These messages can then be
+ enabled/disabled on a per module basis. This mechanism implicitly
+ enables all pr_debug() and dev_dbg() calls. The impact of this
+ compile option is a larger kernel text size of about 2%.
+
+ Usage:
+
+ Dynamic debugging is controlled by the debugfs file,
+ dynamic_printk/modules. This file contains a list of the modules that
+ can be enabled. The format of the file is the module name, followed
+ by a set of flags that can be enabled. The first flag is always the
+ 'enabled' flag. For example:
+
+ <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
+
+ From a live system:
+
+ snd_hda_intel enabled=0
+ fixup enabled=0
+ 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. This mode can be turned off via the above
+ disable command.
