Subject: [PATCH v6 19/57] doc-dyndbg: edit dynamic-debug-howto for brevity, audience
Date: Sun, 4 Sep 2022 15:40:56 -0600 [thread overview]
Message-ID: <20220904214134.408619-20-jim.cromie@gmail.com> (raw)
In-Reply-To: <20220904214134.408619-1-jim.cromie@gmail.com>
Rework/modernize docs:
- use /proc/dynamic_debug/control in examples
its *always* there (when dyndbg is config'd), even when <debugfs> is not.
drop <debugfs> talk, its a distraction here.
- alias ddcmd='echo $* > /proc/dynamic_debug/control
focus on args: declutter, hide boilerplate, make pwd independent.
- swap sections: Viewing before Controlling. control file as Catalog.
- focus on use by a system administrator
add an alias to make examples more readable
drop grep-101 lessons, admins know this.
- use init/main.c as 1st example, thread it thru doc where useful.
everybodys kernel boots, runs these.
- add *prdbg* api section
to the bottom of the file, its for developers more than admins.
move list of api functions there.
- simplify - drop extra words, phrases, sentences.
- add "decorator" flags line to unify "prefix", trim fmlt descriptions

Introduction
============
-This document describes how to use the dynamic debug (dyndbg) feature.
+Dynamic debug allows you to dynamically enable/disable kernel
+debug-print code to obtain additional kernel information.
-Dynamic debug is designed to allow you to dynamically enable/disable
-kernel code to obtain additional kernel information. Currently, if
-``CONFIG_DYNAMIC_DEBUG`` is set, then all ``pr_debug()``/``dev_dbg()`` and
-``print_hex_dump_debug()``/``print_hex_dump_bytes()`` calls can be dynamically
-enabled per-callsite.
+If ``/proc/dynamic_debug/control`` exists, your kernel has dynamic
+debug. You'll need root access (sudo su) to use this.
-If you do not want to enable dynamic debug globally (i.e. in some embedded
-system), you may set ``CONFIG_DYNAMIC_DEBUG_CORE`` as basic support of dynamic
-debug and add ``ccflags := -DDYNAMIC_DEBUG_MODULE`` into the Makefile of any
-modules which you'd like to dynamically debug later.
+Dynamic debug provides:
-If ``CONFIG_DYNAMIC_DEBUG`` is not set, ``print_hex_dump_debug()`` is just
-shortcut for ``print_hex_dump(KERN_DEBUG)``.
+ * a Catalog of all *prdbgs* in your kernel.
+ ``cat /proc/dynamic_debug/control`` to see them.
-For ``print_hex_dump_debug()``/``print_hex_dump_bytes()``, format string is
-its ``prefix_str`` argument, if it is constant string; or ``hexdump``
-in case ``prefix_str`` is built dynamically.
-
-Dynamic debug has even more useful features:
-
- * Simple query language allows turning on and off debugging
- statements by matching any combination of 0 or 1 of:
+ * a Simple query/command language to alter *prdbgs* by selecting on

- format string
- class name (as known/declared by each module)
- * Provides a debugfs control file: ``<debugfs>/dynamic_debug/control``
- which can be read to display the complete list of known debug
- statements, to help guide you
-
-Controlling dynamic debug Behaviour
-===================================
-
-The behaviour of ``pr_debug()``/``dev_dbg()`` are controlled via writing to a
-control file in the 'debugfs' filesystem. Thus, you must first mount
-the debugfs filesystem, in order to make use of this feature.
-Subsequently, we refer to the control file as:
-``<debugfs>/dynamic_debug/control``. For example, if you want to enable
-printing from source file ``svcsock.c``, line 1603 you simply do::
-
- nullarbor:~ # echo 'file svcsock.c line 1603 +p' >
- <debugfs>/dynamic_debug/control
-
-If you make a mistake with the syntax, the write will fail thus::
-
- nullarbor:~ # echo 'file svcsock.c wtf 1 +p' >
- <debugfs>/dynamic_debug/control
- -bash: echo: write error: Invalid argument
-
-Note, for systems without 'debugfs' enabled, the control file can be
-found in ``/proc/dynamic_debug/control``.
-
Viewing Dynamic Debug Behaviour
===============================
-You can view the currently configured behaviour of all the debug
-statements via::
+You can view the currently configured behaviour in the *prdbg* catalog::

- net/sunrpc/svc_rdma.c:341 [svcxprt_rdma]svc_rdma_init =_ "\011max_inline : %d\012"

- ...
+ init/main.c:1179 [main]initcall_blacklist =_ "blacklisting initcall %s\012
+ init/main.c:1218 [main]initcall_blacklisted =_ "initcall %s blacklisted\012"

+ init/main.c:1427 [main]run_init_process =_ " with environment:\012"
+ init/main.c:1429 [main]run_init_process =_ " %s\012"
+The 3rd space-delimited column shows the current flags, preceded by
+a ``=`` for easy use with grep/cut. ``=p`` shows enabled callsites.
-You can also apply standard Unix text manipulation filters to this
-data, e.g.::
+Controlling dynamic debug Behaviour
+===================================
- nullarbor:~ # grep -i rdma <debugfs>/dynamic_debug/control | wc -l
- 62
+The behaviour of *prdbg* sites are controlled by writing
+query/commands to the control file. Example::
- nullarbor:~ # grep -i tcp <debugfs>/dynamic_debug/control | wc -l
- 42
+ # grease the interface
+ :#> alias ddcmd='echo $* > /proc/dynamic_debug/control'
-The third column shows the currently enabled flags for each debug
-statement callsite (see below for definitions of the flags). The
-default value, with no flags enabled, is ``=_``. So you can view all
-the debug statement callsites with any non-default flags::
+ :#> ddcmd '-p; module main func run* +p'
+ :#> grep =p /proc/dynamic_debug/control
+ init/main.c:1424 [main]run_init_process =p " with arguments:\012"
+ init/main.c:1426 [main]run_init_process =p " %s\012"
+ init/main.c:1427 [main]run_init_process =p " with environment:\012"
+ init/main.c:1429 [main]run_init_process =p " %s\012"

- # filename:lineno [module]function flags format
- net/sunrpc/svcsock.c:1603 [sunrpc]svc_send p "svc_process: st_sendto returned %d\012"
+Error messages go to console/syslog::
+
+ :#> ddcmd mode foo +p
+ dyndbg: unknown keyword "mode"
+ dyndbg: query parse failed
+ bash: echo: write error: Invalid argument
+
+If debugfs is also enabled and mounted, ``dynamic_debug/control`` is
+also under the mount-dir, typically ``/sys/kernel/debug/``.
Command Language Reference
==========================
-At the lexical level, a command comprises a sequence of words separated
+At the basic lexical level, a command is a sequence of words separated
by spaces or tabs. So these are all equivalent::
- nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
- <debugfs>/dynamic_debug/control
- nullarbor:~ # echo -n ' file svcsock.c line 1603 +p ' >
- <debugfs>/dynamic_debug/control
- nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
- <debugfs>/dynamic_debug/control
+ :#> ddcmd file svcsock.c line 1603 +p
+ :#> ddcmd "file svcsock.c line 1603 +p"
+ :#> ddcmd ' file svcsock.c line 1603 +p '
Command submissions are bounded by a write() system call.
Multiple commands can be written together, separated by ``;`` or ``\n``::
- ~# echo "func pnpacpi_get_resources +p; func pnp_assign_mem +p" \
- > <debugfs>/dynamic_debug/control
-
-If your query set is big, you can batch them too::
-
- ~# cat query-batch-file > <debugfs>/dynamic_debug/control
+ :#> ddcmd "func pnpacpi_get_resources +p; func pnp_assign_mem +p"
+ :#> ddcmd <<"EOC"
+ func pnpacpi_get_resources +p
+ func pnp_assign_mem +p
+ EOC
+ :#> cat query-batch-file > /proc/dynamic_debug/control
-Another way is to use wildcards. The match rule supports ``*`` (matches
-zero or more characters) and ``?`` (matches exactly one character). For
-example, you can match all usb drivers::
+You can also use wildcards in each query term. The match rule supports
+``*`` (matches zero or more characters) and ``?`` (matches exactly one
+character). For example, you can match all usb drivers::
- ~# echo "file drivers/usb/* +p" > <debugfs>/dynamic_debug/control
+ :#> ddcmd file "drivers/usb/*" +p # "" to suppress shell expansion
-At the syntactical level, a command comprises a sequence of match
-specifications, followed by a flags change specification::
+Syntactically, a command is pairs of keyword values, followed by a
+flags change or setting::
command ::= match-spec* flags-spec
-The match-spec's are used to choose a subset of the known pr_debug()
-callsites to which to apply the flags-spec. Think of them as a query
-with implicit ANDs between each pair. Note that an empty list of
-match-specs will select all debug statement callsites.
+The match-spec's select *prdbgs* from the catalog, upon which to apply
+the flags-spec, all constraints are ANDed together. An absent keyword
+is the same as keyword "*".
-A match specification comprises a keyword, which controls the
-attribute of the callsite to be compared, and a value to compare
-against. Possible keywords are:::
