* | trace-gui: Remove gnome referencesSteven Rostedt2009-12-17
| | | | | | | | | | | | | | | | | | | | The original idea was to use a gnome canvas, but it became more apparent to directly draw into a drawable area. This patch removes all references to gnome, since we do not want to limit this utility to gnome only. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | trace-graph: Add trace-compat to deal with old GTK versionsSteven Rostedt2009-12-17
| | | | | | | | | | | | | | | | | | Testing this code on different boxes, I've found that some older gtk versions don't have all the functions that are needed. This adds those functions in a hack (for older versions anyway) to try to cope with this. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* | Add paging of large data filesSteven Rostedt2009-12-17
| | | | | | | | | | | | | | | | | | Loading a large (100,000+ entry) data file can take a very long time, and is quite annoying to wait for. This patch breaks the data up into pages (10,000 rows per page). Then it lets the user move about the pages with a scroll button. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | Add dialog for event filteringSteven Rostedt2009-12-17
| | | | | | | | | | | | | | Created a dialog that shows all events. Still need to implement the event filtering. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | Add new trace view store model to improve performanceSteven Rostedt2009-12-17
| | | | | | | | | | | | | | With the amount of data needed for loading a trace file, we must implement our own tree view model. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | Add GTK viewer for reading trace dataSteven Rostedt2009-12-17
|/ | | | | | This is the start of adding a GTK front end to read the trace data. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Use python-config scriptSteven Rostedt2009-12-17
| | | | | | | | Need to use the python-config script instead of having hard coded includes. Reported-by: Darren Hart <dvhltc@us.ibm.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-cmd: Start of a tracecmd swig wrapper for pythonDarren Hart2009-12-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a python ctracecmd module for use in rapidly prototyping tracing applications. The interface description is provided in ctracecmd.i, it identifies which functions are available from within python. A test python script is provided as tracecmd-test.py. These bindings are expected to change significantly. Eventually I would like to wrap this automated binding with more pythonic objects, most likely including Trace and Event objects which merge the functionality of tracecmd-input, pevent, record, and event structures. This will make development of python apps much more accessible to many application developers. For now, this is mostly a proof of concept and is no where near complete. It can however open a trace file and read all the events from it, displaying them by CPU in chronological order. V2: o Simplified interface file with SWIG ifdefs in the header files V3: o Move attribute removal to interface file o Remove proxy classes and rename module to ctracecmd o Use the Makefile with a phony python target instead of swig.sh Signed-off-by: Darren Hart <dvhltc@us.ibm.com> LKML-Reference: <4B2A7878.6060209@us.ibm.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Move writing to data file to librarySteven Rostedt2009-12-14
| | | | | | | | We need a way to have other applications easily make the output file. This moves the recording of the trace.dat file to the trace-cmd library. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Add sched_switch plugin to make the events look more like the old pluginSteven Rostedt2009-12-10
| | | | | | | | The event output for scheduler context switches and wakeups changed the output format. This adds a plugin to make those changes look more like the sched_switch plugin. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Create a libtracecmd.soSteven Rostedt2009-11-30
| | | | | | | It may be needed to have a shared object library for trace-cmd. Allow one to be created (not by default). Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Add head compile dependencies for trace-input.c in MakefileSteven Rostedt2009-11-26

* Add both trace-cmd.h and parse-events.h as dependencies in MakefileSteven Rostedt2009-11-26
| | | | | | | Sometimes after modifying trace-cmd.h, some of the objects do not get rebuilt, and causes strange errors. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Remove trace_read_data() and trace_peek_data()Steven Rostedt2009-11-26
| | | | | | | | | | | | | | | | | | The trace_read_data and trace_peek_data() required a global file descriptor for reading. This was kept because the library libparsevent had the function graph tracer implementation and required a callback to read. This code has been moved out of parse_events.c and into a special override function. Now it still uses the global read, but since libtracecmd has a little more scope than libparsevent, we added a thread variable tracecmd_curr_thread_handle This is unique per thread, and is set right after data is read. Yes there are some races, but we can deal with it for now. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Create default event override for function tracerSteven Rostedt2009-11-25
| | | | | | | | The libparsevent currently does special cases for the function tracer. This patch replaces the special case with a event override. This is loaded by libtracecmd. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Move most read functions from trace-read.c to new trace-input.cSteven Rostedt2009-11-25
| | | | | | | | | | | | | | The trace-input.c file belongs to the libtracecmd library. Move the functions from trace-read that will be used as an interface for the library. Note, this commit is a basic move. Only some changing from static to global was done to some functions and variables to keep the code working. But this is a transition commit. This shows the move. The next commits will show the changes to these functions to make the library API more practical. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Start of creating libtracecmd.a librarySteven Rostedt2009-11-25
| | | | | | | | Have libtracecmd.a contain libparevent.a and include trace-util.c. Create a trace-local.h file to be used by the trace-cmd exec itself. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* allow plugins to override the event parsing handlerSteven Rostedt2009-11-24
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds the function to parse_events called pevent_register_event_handler(int id, char *sys_name, char *event_name, pevent_event_handler_func func) If id is >= 0 then the event is searched for by id, and checked against sys_name and event_name if those are non NULL. If id < 0, then the sys_name and event_name are used. If sys_name is non NULL, it will match the event system with that name, otherwise it will just find the first event named event_name. The pevent_event_handler_func is defined as: int (*func)(struct trace_seq *s, void *data, int size); This lets a plugin register a function that will be called in place of the "pretty_print" function for the event.

* Add method to load plugins at trace-cmd report timeSteven Rostedt2009-11-24
| | | | | | | | | | | | | | | | | | | | | | | This adds a method to load a plugin. It looks in the users directory ~/.trace-cmd/plugins and tries to load any file there. To create a plugin simply make a C file that has this minimum format: #include "parse-events.h" int PEVENT_PLUGIN_LOADER(void) { ... } Then compile it with the following method: gcc -c plugin.c -fPIC -o plugin.o gcc -shared -nostartfiles -o plugin Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Separate out comm registry from app and librarySteven Rostedt2009-11-24
| | | | | | | | | | | | The way the comm and pids are associated may be different with different apps. Let the app decide how it will register a mapping of comm and pid. Created trace-util.c file to hold the app side of comms. Create pevent_register_comm to implement the library register routine. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Use a static library instead of a dynamic oneSteven Rostedt2009-11-24
| | | | | | | | A dynamic library will cause pain to users when they find that the tool can not find the library. For now, just use a static library to make the use of the tool more convenient. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* Move trace-seq header into parse-events.hSteven Rostedt2009-11-24
| | | | | | | The functions for trace-seq are moving into the parse-events library. We need to keep the headers more consolidated. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Convert parse-event.h file into a librarySteven Rostedt2009-11-24
| | | | | | | | This is the first step in making a shared library for other applications to use the parse-event functions for parsing the TRACE_EVENT from raw data. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| | | | | | Create entry TAGS to create etags. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* Add trace-seqSteven Rostedt2009-11-16
| | | | | | | | | The trace-seq is a nice utility I wrote for Linux. It makes a page size buffer that that can be written to with a printf,puts,putc interface. This is perfect for having the same routine write the same type of output, and used separately. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* add -std=gnu99 to compilingSteven Rostedt2009-10-14
| | | | | | | | | Perf uses -std=gnu99 which causes some strange side effects. To keep parse-events.c close to what is in perf, we use the same option. Namely, it makes us typecast the options for "%a" in the sscanf to float. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
