tools/liblockdep: Account for bitfield changes in lockdeps lock_acquire

2014-07-07T16:20:16Z

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 Signed-off-by: Sasha Levin

tools/liblockdep: Remove debug print left over from development

2014-07-07T16:14:27Z

Remove a debug print in init_preload() which was left over from development and isn't usefull at all currently. It was also causing false positive test results. Reported-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools/liblockdep: Fix comparison of a boolean value with a value of 2

2014-07-07T16:02:21Z

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.

tools lib traceevent: Added support for __get_bitmask() macro

2014-06-07T21:33:37Z

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 Signed-off-by: Steven Rostedt Acked-by: Namhyung Kim Tested-by: Javi Merino Link: http://lkml.kernel.org/r/20140603032224.229186537@goodmis.org Signed-off-by: Jiri Olsa

tools lib traceevent: Add options to function plugin

2014-06-07T21:33:37Z

Add the options "parent" and "indent" to the function plugin. When parent is set, the output looks like this: function: fsnotify_modify <-- vfs_write function: zone_statistics <-- get_page_from_freelist function: __inc_zone_state <-- zone_statistics function: inotify_inode_queue_event <-- fsnotify_modify function: fsnotify_parent <-- fsnotify_modify function: __inc_zone_state <-- zone_statistics function: __fsnotify_parent <-- fsnotify_parent function: inotify_dentry_parent_queue_event <-- fsnotify_parent function: add_to_page_cache_lru <-- do_read_cache_page When it's not set, it looks like: function: fsnotify_modify function: zone_statistics function: __inc_zone_state function: inotify_inode_queue_event function: fsnotify_parent function: __inc_zone_state function: __fsnotify_parent function: inotify_dentry_parent_queue_event function: add_to_page_cache_lru When the otpion "indent" is not set, it looks like this: function: fsnotify_modify <-- vfs_write function: zone_statistics <-- get_page_from_freelist function: __inc_zone_state <-- zone_statistics function: inotify_inode_queue_event <-- fsnotify_modify function: fsnotify_parent <-- fsnotify_modify function: __inc_zone_state <-- zone_statistics function: __fsnotify_parent <-- fsnotify_parent function: inotify_dentry_parent_queue_event <-- fsnotify_parent function: add_to_page_cache_lru <-- do_read_cache_page Signed-off-by: Steven Rostedt Acked-by: Namhyung Kim Link: http://lkml.kernel.org/r/20140603032224.056940410@goodmis.org Signed-off-by: Jiri Olsa

tools lib traceevent: Add options to plugins

2014-06-07T21:33:36Z

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.

tools lib traceevent: Add flag to not load event plugins

2014-06-07T21:33:36Z

Add a flag to pevent that will let the callers be able to set it and keep the system, and perhaps even normal plugins from being loaded. This is useful when plugins might hide certain information and seeing the raw events shows what may be going on.
