Abstract: In one embodiment, tasks executing on a data processing system can be associated with a Quality of Service (QoS) classification that is used to determine the priority values for multiple subsystems of the data processing system. The QoS classifications are propagated when tasks interact and the QoS classes are interpreted a multiple levels of the system to determine the priority values to set for the tasks. In one embodiment, one or more sensors coupled with the data processing system monitor a set of system conditions that are used in part to determine the priority values to set for a QoS class.

Abstract: Services for a personal electronic device are provided through which a form of background processing or multitasking is supported. The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. By way of example, inactive network applications (e.g., VOIP applications) may be placed in a suspended state until a message is received targeting the application (e.g., an incoming phone call or a heartbeat needed message). The user application may be placed into the background state to respond to the message and then returned to the non-active state (e.g., if the message was a heartbeat needed) message or to the foreground state if appropriate (e.g., the user elects to answer the incoming call).

To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. By way of example, an application that may normally be placed into the background state may instead be terminated if it controls a lock on a shared system resource.
