Selecting the activity source

You can select an activity source from the drop-down menu in the bottom right corner of the Timeline view as the focus of the Heat Map, Core Map, or Cluster Map.

By default, CPU Activity is selected.

If you select a different activity source to focus on, the Heat Map, Core Map, or Cluster Map in the details panel updates to show a map of threads and processes for the newly selected source. For example, if you select GPU Fragment, the map updates to show activity for the GPU fragment processor only. The GPU activity sources are only available if your Arm^® Mali^™-based target is configured to support Mali GPU-specific profiling.
