perf trace scripting: remove system-wide param from shell scriptsIncluding -a unconditionally when recording doesn't allow for theoption of running scripts without it. Future patches will add add itback if needed at run-time.Signed-off-by: Tom Zanussi Acked-by: Arnaldo Carvalho de Melo List of files: /linux-6.15/tools/perf/scripts/python/bin/sched-migration-record

perf: New migration tool overviewThis brings a GUI tool that displays an overview of the loadof tasks proportion in each CPUs.The CPUs forward progress is cut in timeslices. A new timesliceis created for every runqueue event: a task gets pushed out orpulled in the runqueue.For each timeslice, every CPUs rectangle is colored with a redpower 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, withoutany distinction against the scheduler policy of the tasks, fornow.Also for each timeslice, the event origin is depicted on theCPUs that triggered it using a thin colored line on top of therectangle 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 detailsand the runqueue state.The CPU rectangles can be navigated using the usual arrowcontrols. Horizontal zooming in/out is possible with the"+" and "-" buttons.Signed-off-by: Frederic Weisbecker Cc: Peter Zijlstra Cc: Arnaldo Carvalho de Melo Cc: Li Zefan Cc: Steven Rostedt Cc: Tom Zanussi Cc: Mike Galbraith Cc: Venkatesh Pallipadi Cc: Pierre Tardy Cc: Nikhil Rao Cc: Li Zefan List of files: /linux-6.15/tools/perf/scripts/python/bin/sched-migration-record
