Commiter note: This fixes a bug introduced in 4af8b35, there is no need to shift pgoff twice, the show_map_vma routine in fs/proc/task_mmu.c already converts it from the number of pages to the size in bytes, and that is what appears in /proc/PID/map.

Migrate out events may happen on tasks that are not in the runqueue, for example this is the case for tasks that are sleeping. In this case, we don't want to log the migrate out event in the source runqueue because the task is not eventually in the runqueue and we have already logged its sleep event.

2010-08-02perf: New migration tool overviewFrederic Weisbecker3-0/+639
This brings a GUI tool that displays an overview of the load of tasks proportion in each CPUs. The CPUs forward progress is cut in timeslices. A new timeslice is created for every runqueue event: a task gets pushed out or pulled in the runqueue. For each timeslice, every CPUs rectangle is colored with a red power that describes the local load against the total load. This more red is the rectangle, the higher is the given CPU load. This load is the number of tasks running on the CPU, without any distinction against the scheduler policy of the tasks, for now. Also for each timeslice, the event origin is depicted on the CPUs that triggered it using a thin colored line on top of the rectangle timeslice. These events are: * sleep: a task went to sleep and has then been pulled out the runqueue. The origin color in the thin line is dark blue. * wake up: a task woke up and has then been pushed in the runqueue. The origin color is yellow. * wake up new: a new task woke up and has then been pushed in the runqueue. The origin color is green. * migrate in: a task migrated in the runqueue due to a load balancing operation. The origin color is violet. * migrate out: reverse of the previous one. Migrate in events usually have paired migrate out events in another runqueue. The origin color is light blue. Clicking on a timeslice provides the runqueue event details and the runqueue state. The CPU rectangles can be navigated using the usual arrow controls. Horizontal zooming in/out is possible with the "+" and "-" buttons.

For long running sessions with many threads with short lifetimes the amount of memory that the buildid process takes is too much. Since we don't have hist_entries that may be pointing to them, we can just release the resources associated with each thread when the exit (PERF_RECORD_EXIT) event is received.

Changes: * Simplification of the main search loop on dso__load() * Replace the search with a 2-pass search: * First, try to find an image with a proper symtab. * Second, repeat the search, accepting dynsym. A second scan should only ever happen when needed debug images are missing from the buildid cache or stale, i.e., when the cache is out of sync. Currently, the second scan also happens when using separated debug images, since the caching logic doesn't currently know how to cache those. Improvements to the cache behaviour ought to solve that.

If we have a buildid, then we never want to load an image which has no buildid, or which has a different buildid, so it makes sense for the check to be built into dso__load and not done separately. This is fine for old distros which don't use buildid at all since we do no check in that case. This refactoring also alleviates some subtle race condition issues by not opening ELF images twice to check the buildid and then load the symbols, which could lead to weirdness if an image is replaced under our feet.

2010-07-27perf ui: New hists tree widgetArnaldo Carvalho de Melo4-311/+678
The stock newt checkbox tree widget we were using was not really suitable for hist entry + callchain browsing. The problems with it were manifold: - We needed to traverse the whole hist_entry rb_tree to add each entry + callchains beforehand. - No control over the colors used for each row So a new tree widget, based mostly on slang, was written. It extends the ui_browser class already used for annotate to allow the user to fold/unfold branches in the callchains tree, using extra fields in the symbol_map class that is embedded in hist_entry and callchain_node instances to store the folding state and when changing this state calculates the number of rows that are produced when showing a particular hist_entry instance. This greatly speeds up browsing as we don't have to upfront touch all the entries and only calculate callchain related operations when some callchain branch is actually unfolded. The memory footprint is also reduced as the data structure is not duplicated, just some extra fields for controling callchain state and to simplify the process of seeking thru entries (nr_rows, row_offset) were added.

2010-07-27perf ui: Show the scroll bar over the left window frameArnaldo Carvalho de Melo1-2/+2
So that we gain two columns and look more like classical (at least in TUIs) scroll bars bars.

2010-07-27perf ui: Consider the refreshed dimensions in ui_browser__showArnaldo Carvalho de Melo1-2/+4
When we call ui_browser__show we may have called ui_browser__refresh_dimensions to check if the maximum lenght for the contained entries changed, such as when zooming in and out DSOs or threads in the hist browser. For that to happen we must delete the old form, that will take care of deleting the vertical scrollbar, etc, and then recreate them, with the new dimensions.

2010-07-27tools/firewire: nosy-dump: increment program versionStefan Richter1-2/+2
Since version 0.3 from Kristian's repository, there should actually be no change in functionality except for the x86-64 fix. Nevertheless, make it distinct from the original nosy-dump --- just in case and also because of potential future changes. Signed-off-by: Stefan Richter <[email protected]>
