From 880d22f2470af6037715b7f6eb083b6ec5561d92 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Tue, 20 Jul 2010 21:55:33 +0200 Subject: perf: New migration tool overview 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.

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. This fixes timeslices that spuriously propagate a sleep event from the previous timeslice.
