Introduction
|
||||
============
|
||||
|
||||
This document describes how to use the dynamic debug (ddebug) feature.
|
||||
|
||||
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_debug() calls can be
|
||||
dynamically enabled per-callsite.
|
||||
|
||||
Dynamic debug has even more useful features:
|
||||
|
||||
* Simple query language allows turning on and off debugging statements by
|
||||
matching any combination of:
|
||||
|
||||
- source filename
|
||||
- function name
|
||||
- line number (including ranges of line numbers)
|
||||
- module name
|
||||
- format string
|
||||
|
||||
* 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_debug()s 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
|
||||
|
||||
Viewing Dynamic Debug Behaviour
|
||||
===========================
|
||||
|
||||
You can view the currently configured behaviour of all the debug statements
|
||||
via:
|
||||
|
||||
nullarbor:~ # cat <debugfs>/dynamic_debug/control
|
||||
# filename:lineno [module]function flags format
|
||||
/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:323 [svcxprt_rdma]svc_rdma_cleanup - "SVCRDMA Module Removed, deregister RPC RDMA transport\012"
|
||||
/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:341 [svcxprt_rdma]svc_rdma_init - "\011max_inline : %d\012"
|
||||
/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:340 [svcxprt_rdma]svc_rdma_init - "\011sq_depth : %d\012"
|
||||
/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svc_rdma.c:338 [svcxprt_rdma]svc_rdma_init - "\011max_requests : %d\012"
|
||||
...
|
||||
|
||||
|
||||
You can also apply standard Unix text manipulation filters to this
|
||||
data, e.g.
|
||||
|
||||
nullarbor:~ # grep -i rdma <debugfs>/dynamic_debug/control | wc -l
|
||||
62
|
||||
|
||||
nullarbor:~ # grep -i tcp <debugfs>/dynamic_debug/control | wc -l
|
||||
42
|
||||
|
||||
Note in particular that the third column shows the enabled behaviour
|
||||
flags for each debug statement callsite (see below for definitions of the
|
||||
flags). The default value, no extra behaviour enabled, is "-". So
|
||||
you can view all the debug statement callsites with any non-default flags:
|
||||
|
||||
nullarbor:~ # awk '$3 != "-"' <debugfs>/dynamic_debug/control
|
||||
# filename:lineno [module]function flags format
|
||||
/usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c:1603 [sunrpc]svc_send p "svc_process: st_sendto returned %d\012"
|
||||
|
||||
|
||||
Command Language Reference
|
||||
==========================
|
||||
|
||||
At the lexical level, a command comprises a sequence of words separated
|
||||
by whitespace characters. Note that newlines are treated as word
|
||||
separators and do *not* end a command or allow multiple commands to
|
||||
be done together. So these are all equivalent:
|
||||
|
||||
nullarbor:~ # echo -c 'file svcsock.c line 1603 +p' >
|
||||
<debugfs>/dynamic_debug/control
|
||||
nullarbor:~ # echo -c ' file svcsock.c line 1603 +p ' >
|
||||
<debugfs>/dynamic_debug/control
|
||||
nullarbor:~ # echo -c 'file svcsock.c\nline 1603 +p' >
|
||||
<debugfs>/dynamic_debug/control
|
||||
nullarbor:~ # echo -n 'file svcsock.c line 1603 +p' >
|
||||
<debugfs>/dynamic_debug/control
|
||||
|
||||
Commands are bounded by a write() system call. If you want to do
|
||||
multiple commands you need to do a separate "echo" for each, like:
|
||||
|
||||
nullarbor:~ # echo 'file svcsock.c line 1603 +p' > /proc/dprintk ;\
|
||||
> echo 'file svcsock.c line 1563 +p' > /proc/dprintk
|
||||
|
||||
or even like:
|
||||
|
||||
nullarbor:~ # (
|
||||
> echo 'file svcsock.c line 1603 +p' ;\
|
||||
> echo 'file svcsock.c line 1563 +p' ;\
|
||||
> ) > /proc/dprintk
|
||||
|
||||
At the syntactical level, a command comprises a sequence of match
|
||||
specifications, followed by a flags change specification.
|
||||
|
||||
command ::= match-spec* flags-spec
|
||||
|
||||
The match-spec's are used to choose a subset of the known dprintk()
|
||||
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 is possible, but is not very useful because it will not
|
||||
match any debug statement callsites.
|
||||
|
||||
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:
|
||||
|
||||
match-spec ::= 'func' string |
|
||||
'file' string |
|
||||
'module' string |
|
||||
'format' string |
|
||||
'line' line-range
|
||||
|
||||
line-range ::= lineno |
|
||||
'-'lineno |
|
||||
lineno'-' |
|
||||
lineno'-'lineno
|
||||
// Note: line-range cannot contain space, e.g.
|
||||
// "1-30" is valid range but "1 - 30" is not.
|
||||
|
||||
lineno ::= unsigned-int
|
||||
|
||||
The meanings of each keyword are:
|
||||
|
||||
func
|
||||
The given string is compared against the function name
|
||||
of each callsite. Example:
|
||||
|
||||
func svc_tcp_accept
|
||||
|
||||
file
|
||||
The given string is compared against either the full
|
||||
pathname or the basename of the source file of each
|
||||
callsite. Examples:
|
||||
|
||||
file svcsock.c
|
||||
file /usr/src/packages/BUILD/sgi-enhancednfs-1.4/default/net/sunrpc/svcsock.c
|
||||
|
||||
module
|
||||
The given string is compared against the module name
|
||||
of each callsite. The module name is the string as
|
||||
seen in "lsmod", i.e. without the directory or the .ko
|
||||
suffix and with '-' changed to '_'. Examples:
|
||||
|
||||
module sunrpc
|
||||
module nfsd
|
||||
|
||||
format
|
||||
The given string is searched for in the dynamic debug format
|
||||
string. Note that the string does not need to match the
|
||||
entire format, only some part. Whitespace and other
|
||||
special characters can be escaped using C octal character
|
||||
escape \ooo notation, e.g. the space character is \040.
|
||||
Alternatively, the string can be enclosed in double quote
|
||||
characters (") or single quote characters (').
|
||||
Examples:
|
||||
|
||||
format svcrdma: // many of the NFS/RDMA server dprintks
|
||||
format readahead // some dprintks in the readahead cache
|
||||
format nfsd:\040SETATTR // one way to match a format with whitespace
|
||||
format "nfsd: SETATTR" // a neater way to match a format with whitespace
|
||||
format 'nfsd: SETATTR' // yet another way to match a format with whitespace
|
||||
|
||||
line
|
||||
The given line number or range of line numbers is compared
|
||||
against the line number of each dprintk() callsite. A single
|
||||
line number matches the callsite line number exactly. A
|
||||
range of line numbers matches any callsite between the first
|
||||
and last line number inclusive. An empty first number means
|
||||
the first line in the file, an empty line number means the
|
||||
last number in the file. Examples:
|
||||
|
||||
line 1603 // exactly line 1603
|
||||
line 1600-1605 // the six lines from line 1600 to line 1605
|
||||
line -1605 // the 1605 lines from line 1 to line 1605
|
||||
line 1600- // all lines from line 1600 to the end of the file
|
||||
|
||||
The flags specification comprises a change operation followed
|
||||
by one or more flag characters. The change operation is one
|
||||
of the characters:
|
||||
|
||||
-
|
||||
remove the given flags
|
||||
|
||||
+
|
||||
add the given flags
|
||||
|
||||
=
|
||||
set the flags to the given flags
|
||||
|
||||
The flags are:
|
||||
|
||||
p
|
||||
Causes a printk() message to be emitted to dmesg
|
||||
|
||||
Note the regexp ^[-+=][scp]+$ matches a flags specification.
|
||||
Note also that there is no convenient syntax to remove all
|
||||
the flags at once, you need to use "-psc".

||||

||||
