* kernelshark: Make the programs depend on the tracecmd librarySteven Rostedt2010-01-04
| | | | | | | | | | | | If we do a make clean, still allow the dependencies of the programs to create the library. That is: $ make clean $ make trace-view Needs to build the libtracecmd.a file. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-view: Include sched switch in task filteringSteven Rostedt2010-01-04
| | | | | | | Include when a task is scheduled in as an event in the filtered list. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-view: Fix trace_view_store_get_timestamp_visible_row()Steven Rostedt2010-01-04
| | | | | | | | | | | The search used the size of the actual_rows array, and not the size of what was visible. The visible_rows use the array, but anything outside the visible rows are just left overs. Using the bsearch on the entire array causes errors in the search. It should only use the subset that is visible. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-view: Fix searching by timestamp for filtered listsSteven Rostedt2010-01-04
| | | | | | | | | | | | | When a list is filtered, the search_for_record_by_timestamp() was returning incorrect values because the rows_ts_cmp() was using the pointer the array was pointing to go to the next record. But if that record was not visible or the next record should have been on another CPU, it would break the bsearch. The correct approach is to look at the next record in the array, not the per cpu list. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-view: Do not call helper function to select row in trace_view_select()Steven Rostedt2010-01-04
| | | | | | | The helper function to select a row just adds overhead for trace_view_select(). Just call the selection directly. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* trace-view: Return only visible recordsSteven Rostedt2010-01-04
| | | | | | | | The trace_view_store_get_timestamp_visible_row() did not return only visible rows, but also invisible ones. This patch fixes the code to only return the visible rows. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| * trace-cmd: Have tracecmd_read_cpu_first() return the first recordSteven Rostedt2010-01-04
| | | | | | | | | | | | | | | | | | | | | | There was a bug with tracecmd_read_cpu_first() where it may not return the first record for a CPU. If another record was read on the first page the get_page() function would return without reseting the index. The tracecmd_read_cpu_first() needs to always reset the index before returning tracecmd_read_data(). Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | trace-graph: Move task filter code to trace-hash.[ch]Steven Rostedt2010-01-04
| | | | | | | | | | | | | | | | | | In order to make the trace tree of kernelshark work better with the trace-graph, move the filtering code of tasks out of trace-graph.c into trace-hash.c. This will allow the trace-tree to be more flexible in its filtering too. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | trace-graph: Disable filter when last task is removedSteven Rostedt2010-01-04
| | | | | | | | | | | | When the last task is removed from the filter, disable the filter. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | kernel-shark: Allow filtering of graph from tree viewSteven Rostedt2010-01-04
| | | | | | | | | | | | | | | | Let the tree view pop up menu filter the graph as well. This makes finding tasks to filter on easier, as it is easier to search for a task from the tree view than with the graph. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| * trace-cmd: Add plugin_kmem for showing function names of call sitesSteven Rostedt2009-12-31
| | | | | | | | | | | | | | | | | | | | | | The kmem events only show a useless hex symbol for the call site name. This adds a plugin to do a lookup of the function name and still print the rest of the event format. Also adds pevent_find_function_address() to let the plugin show the offset into the function as well. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
| * trace-cmd: Allow plugin handlers to let the default print to also happenSteven Rostedt2009-12-31
| | | | | | | | | | | | | | | | | | | | A plugin may only need to translate part of the field, or if it fails to translate, it may want the default to print. Now if a plugin handler returns something other than 0, the default print handler will take place. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

* | trace-graph: Remove hack to redraw graphSteven Rostedt2009-12-31
| | | | | | | | | | | | | | | | An old hack was still in place to redraw the graph after zooming in and out. Replace it with the redraw function and the update_with_backend(). Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | trace-graph: Add task filtering popup menusSteven Rostedt2009-12-31
| | | | | | | | | | | | | | | | | | Add popup menus to graph that allows the use to add or remove tasks from the filter, as well as to enable or disable the filter. This only adds the popup menus, the filtering is not actually done yet. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | trace-graph: Replace hash looping with a faster hashSteven Rostedt2009-12-31
| | | | | | | | | | | | | | | | | | Did a little more research and found a nice hash that is quick and pretty powerful. Based off of Paul Hsieh's super fast hash: http://www.azillionmonkeys.com/qed/hash.html Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | trace-graph: Add a little better pid hash functionSteven Rostedt2009-12-31
| | | | | | | | | | | | | | | | This adds a little better pid hash function that will give a better difference in colors for tasks than the previous hash algorithm. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* | trace-graph: Fix color of task starting windowSteven Rostedt2009-12-31
| | | | | | | | | | | | | | | | | | The color was not being set up for the box if a task other than idle was the first event on a CPU. The gc variable used to draw the task box was not initialized and the color of the task was random at the start. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>

| * | trace-view: Self-adjusting fixed width trace-viewDarren Hart2009-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By using fixed width columns and fixed height rows, the view can now render over 400k events without any noticable lag. This makes it so large traces can now be viewed in one "page" of the trace-view-model. The new trace-view-data-func() is called when the view wants to render cell (which it only has to do when it's visible now that we use fixed sizings). Here we check the string width in pixels and resize the column if necessary. By tracking the max character width of each column, we can avoid doing the expensive Pango pixel width test as often. By adding a little extra padding, we anticipate one more character, further reducing the overhead. The first full scroll down and up shows no noticable lag due to these calculations once the optimizations were implemented. V2: fix an unused var warning and use a long when casting to a pointer.

* | | trace-graph: Work on fixing the zooming and horizontal scrollingSteven Rostedt2009-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason zooming in too much will cause the horizontal scrolling to get out of sync. This is probably a rounding error or some other strange bug. This patch cleans some of the code up and fixes parts of it. But there's still a bug to swat.

| * trace-cmd: Python EventStore and record memory managementDarren Hart2009-12-30
| | | | | | | | | | | | | | | | | | | | | | | | Add a python EventStore instead of a generic gtk.ListStore. Load time is reduced 50% although still 15x slower than the C version. Add the proper freeing of the record to the Event destructor rather than setting ownership of the pointer to Python. The latter causes swig to call free() on the record rather than free_record() which does some intelligent things regarding the mmap. Signed-off-by: Darren Hart <dvhltc@us.ibm.com>
