Multi-core processing system having cache coherency in dormant mode

Aspects of the disclosure provide a method for power mode switching. The method includes sending a pausing request to an application executed in an electronic system. The pausing request informs the application of an intent to switch the electronic system from an active mode to a power saving mode that causes the electronic system to pause executing the application. Then, the method includes determining that the application accepts the pausing request, and configuring the electronic system into the power saving mode, such that the application pauses at a pausing point determined in response to the pausing request.
