Dynamic debug: Add more flags

2011-02-03T23:39:16+00:00

Add flags that allow the user to specify via debugfs whether or not the
module name, function name, line number and/or thread ID have to be
included in the printed message.

dynamic debug: Fix build issue with older gcc

2011-01-08T04:36:59+00:00

On older gcc (3.3) dynamic debug fails to compile:

include/net/inet_connection_sock.h: In function `inet_csk_reset_xmit_timer':
include/net/inet_connection_sock.h:236: error: duplicate label declaration `do_printk'
include/net/inet_connection_sock.h:219: error: this is a previous declaration
include/net/inet_connection_sock.h:236: error: duplicate label declaration `out'
include/net/inet_connection_sock.h:219: error: this is a previous declaration
include/net/inet_connection_sock.h:236: error: duplicate label `do_printk'
include/net/inet_connection_sock.h:236: error: duplicate label `out'

Fix, by reverting the usage of JUMP_LABEL() in dynamic debug for now.

module: initialize module dynamic debug later

2010-07-05T03:17:22+00:00

We should initialize the module dynamic debug datastructures
only after determining that the module is not loaded yet. This
fixes a bug that introduced in 2.6.35-rc2, where when a trying
to load a module twice, we also load it's dynamic printing data
twice which causes all sorts of nasty issues. Also handle
the dynamic debug cleanup later on failure.

dynamic_debug.h/kernel.h: Remove KBUILD_MODNAME from dynamic_pr_debug

2009-12-15T16:53:25+00:00

If CONFIG_DYNAMIC_DEBUG is enabled and a source file has:

#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
#include 

dynamic_debug.h will duplicate KBUILD_MODNAME
in the output string.

Remove the use of KBUILD_MODNAME from the
output format string generated by dynamic_debug.h

If CONFIG_DYNAMIC_DEBUG is not enabled, no compile-time
check is done to printk/dev_printk arguments.

Add it.

Driver core: remove pr_fmt() from dynamic_dev_dbg() printk

2009-04-16T23:17:11+00:00

When pr_fmt() was added to the pr_debug() code, we added it not only to the
dynamic_pr_debug() function, but also to the dynamic_dev_dbg() funciton.
However, dev_dbg() doesn't make use of pr_fmt(), so neither should
dynamic_dev_dbg().

Dynamic debug: fix pr_fmt() build error

2009-03-24T23:38:27+00:00

When CONFIG_DYNAMIC_DEBUG is enabled, allow callers of pr_debug()
to provide their own definition of pr_fmt() even if that definition
uses tricks like

#define pr_fmt(fmt) "%s:" fmt, __func__
