      "message": "driver core: basic infrastructure for per-module dynamic debug messages\n\nBase infrastructure to enable per-module debug messages.\n\nI\u0027ve introduced CONFIG_DYNAMIC_PRINTK_DEBUG, which when enabled centralizes\ncontrol of debugging statements on a per-module basis in one /proc file,\ncurrently, \u003cdebugfs\u003e/dynamic_printk/modules. When, CONFIG_DYNAMIC_PRINTK_DEBUG,\nis not set, debugging statements can still be enabled as before, often by\ndefining \u0027DEBUG\u0027 for the proper compilation unit. Thus, this patch set has no\naffect when CONFIG_DYNAMIC_PRINTK_DEBUG is not set.\n\nThe infrastructure currently ties into all pr_debug() and dev_dbg() calls. That\nis, if CONFIG_DYNAMIC_PRINTK_DEBUG is set, all pr_debug() and dev_dbg() calls\ncan be dynamically enabled/disabled on a per-module basis.\n\nFuture plans include extending this functionality to subsystems, that define \ntheir own debug levels and flags.\n\nUsage:\n\nDynamic debugging is controlled by the debugfs file, \n\u003cdebugfs\u003e/dynamic_printk/modules. This file contains a list of the modules that\ncan be enabled. The format of the file is as follows:\n\n\t\u003cmodule_name\u003e \u003cenabled\u003d0/1\u003e\n\t\t.\n\t\t.\n\t\t.\n\n\t\u003cmodule_name\u003e : Name of the module in which the debug call resides\n\t\u003cenabled\u003d0/1\u003e : whether the messages are enabled or not\n\nFor example:\n\n\tsnd_hda_intel enabled\u003d0\n\tfixup enabled\u003d1\n\tdriver enabled\u003d0\n\nEnable a module:\n\n\t$echo \"set enabled\u003d1 \u003cmodule_name\u003e\" \u003e dynamic_printk/modules\n\nDisable a module:\n\n\t$echo \"set enabled\u003d0 \u003cmodule_name\u003e\" \u003e dynamic_printk/modules\n\nEnable all modules:\n\n\t$echo \"set enabled\u003d1 all\" \u003e dynamic_printk/modules\n\nDisable all modules:\n\n\t$echo \"set enabled\u003d0 all\" \u003e dynamic_printk/modules\n\nFinally, passing \"dynamic_printk\" at the command line enables\ndebugging for all modules. This mode can be turned off via the above\ndisable command.\n\n[gkh: minor cleanups and tweaks to make the build work quietly]\n\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n\n\n"
