2014-07-07tools/liblockdep: Account for bitfield changes in lockdeps lock_acquireS. Lockwood-Childs3-14/+14
Commit fb9edbe984 shortened held_lock->check from a 2-bit field to a 1-bit field. Make liblockdep compatible with the new definition by passing check=1 to lock_acquire() calls, rather than the old value check=2 (which inadvertently disabled checks by overflowing to 0). Without this fix, several of the test cases in liblockdep run_tests.sh were failing. Signed-off-by: S. Lockwood-Childs <sjl@vctlabs.com> Signed-off-by: Sasha Levin <sasha.levin@oracle.com>

Comparison of a boolean value (!__init_state) with a value of 2 (done) as currently happens in the code is unlikely to succeed and causes repeated initialization of the pthread function pointers. Instead, remove boolean comparison so that we would initialize said function pointers only once.

2014-06-08tools lib traceevent: Added support for __get_bitmask() macroSteven Rostedt (Red Hat)2-0/+120
Coming in v3.16, trace events will be able to save bitmasks in raw format in the ring buffer and output it with the __get_bitmask() macro. In order for userspace tools to parse this, it must be able to handle the __get_bitmask() call and be able to convert the data that's in the ring buffer into a nice bitmask format. The output is similar to what the kernel uses to print bitmasks, with a comma separator every 4 bytes (8 characters). This allows for cpumasks to also be saved efficiently. The first user is the thermal:thermal_power_limit event which has the following output: thermal_power_limit: cpus=0000000f freq=1900000 cdev_state=0 power=5252 Link: http://lkml.kernel.org/r/20140506132238.22e136d1@gandalf.local.home Suggested-by: Javi Merino <javi.merino@arm.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Namhyung Kim <namhyung@kernel.org> Tested-by: Javi Merino <javi.merino@arm.com> Link: http://lkml.kernel.org/r/20140603032224.229186537@goodmis.org Signed-off-by: Jiri Olsa <jolsa@kernel.org>

2014-06-08tools lib traceevent: Add options to pluginsSteven Rostedt2-3/+209
The traceevent plugins allows developers to have their events print out information that is more advanced than what can be achieved by the trace event format files. As these plugins are used on the userspace side of the tracing tools, it is only logical that the tools should be able to produce different types of output for the events. The types of events still need to be defined by the plugins thus we need a way to pass information from the tool to the plugin to specify what type of information to be shown. Not only does the information need to be passed by the tool to plugin, but the plugin also requires a way to notify the tool of what options it can provide. This builds the plugin option infrastructure that is taken from trace-cmd that is used to allow plugins to produce different output based on the options specified by the tool.

2014-04-23tools lib traceevent: Fix memory leak in pretty_print()Steven Rostedt1-0/+1
Commit 12e55569a244 "tools lib traceevent: Use helper trace-seq in print functions like kernel does" added a extra trace_seq helper to process string arguments like the kernel does it. But the difference between the kernel and the userspace library is that the kernel's trace_seq structure has a static allocated buffer. The userspace one has a dynamically allocated one. It requires a trace_seq_destroy(), otherwise it produces a nasty memory leak.

The return value for pevent_filter_match() is suppose to return FILTER_NONE if the event doesn't have a filter, and FILTER_NOEXIST if there is no filter at all. But the change 41e12e580a7 "tools lib traceevent: Refactor pevent_filter_match() to get rid of die()" replaced the return value with PEVENT_ERRNO__* values and added "backward compatibility" macros that used the old names. Unfortunately, the NOEXIST and NONE macros were swapped, and this broke users that use the old return names.

2014-01-23perf tools: Fix traceevent plugin path definitionsJosh Boyer1-1/+1
The plugindir_SQ definition contains $(prefix) which is not needed as the $(libdir) definition already contains prefix in it. This leads to the path including an extra prefix in it, e.g. /usr/usr/lib64. The -DPLUGIN_DIR defintion includes DESTDIR. This is incorrect, as it sets the plugin search path to include the value of DESTDIR. DESTDIR is a mechanism to install in a non-standard location such as a chroot or an RPM build root. In the RPM case, this leads to the search path being incorrect after the resulting RPM is installed (or in some cases an RPM build failure). Remove both of these unnecessary inclusions.
