Window: Core Wake-ups

Displays the causes of core wake-ups by module and package, and over time.

To access this window: Click the Core Wake-ups sub-tab in the Platform Power analysis result tab.

The Core Wake-ups window is available in the Platform Power Analysis viewpoint that provides power-related data collected on a target system. This window displays the reasons and objects that caused of core wake-ups, grouped by module and package, and over time.

Note

Platform Power Analysis viewpoint is available as part of energy analysis. Energy analysis is provided by the Intel® VTune™ Amplifier for Systems only. Energy analysis collection is supported for target Android*, Windows* or Linux* devices.

Use this window to identify wake-up reasons on each core and to investigate the wake-up reasons at specific timeframes during the data collection.

Core Wake-ups Pane

The Core Wake-ups pane displays information about events that caused the core to switch from a sleep state to an active state. For more information, see Core Wake-ups Pane.

Timeline Pane

The Timeline pane shows the time spent in the active state (C0) or the various sleep states (Cn) represented by different colors. The pane also shows the wake-up band, which represents the wake-up objects that caused the core to switch from a sleep state to an active state. Each wake-up object type uses a unique color. By hovering over the band, you can view all of the wake-up objects at that point in time, including details such as wake-up object type, start time, and duration. You can filter the wake-up types shown using the Core Wake-ups pane. For more information, see Timeline Pane.
