Abstract: A request for a high voltage mode is received and a high voltage timer is started in response to determining that a remaining amount of high voltage credits exceeds a voltage switch threshold value. A switch to the high voltage mode is made in response to the request. A low voltage mode is switched to in response to an indication. The request may be received from an application running on a data processing system. If the indication is that the high voltage timer has expired, a low voltage timer is started in response to switching to low voltage mode. If the high voltage request is still active when the low voltage timer expires, a switch back to high voltage mode occurs and a new high voltage timer is started.

Abstract: Methods and systems for managing power consumption in data processing systems are described. In one embodiment, a data processing system includes a general purpose processing unit, a graphics processing unit (GPU), at least one peripheral interface controller, at least one bus coupled to the general purpose processing unit, and a power controller coupled to at least the general purpose processing unit and the GPU. The power controller is configured to turn power off for the general purpose processing unit in response to a first state of an instruction queue of the general purpose processing unit and is configured to turn power off for the GPU in response to a second state of an instruction queue of the GPU. The first state and the second state represent an instruction queue having either no instructions or instructions for only future events or actions.

In one embodiment, an exemplary data processing system includes a processing system, an interrupt controller coupled to the processing system and a timer circuit which is coupled to the interrupt controller. The interrupt controller is configured to provide a first interrupt signal and a second interrupt signal to the processing system.

Abstract: A method and an apparatus for configuring a key stored within a secure storage area (e.g., ROM) of a device including one of enabling and disabling the key according to a predetermined condition to execute a code image are described. The key may uniquely identify the device. The code image may be loaded from a provider satisfying a predetermined condition to set up at least one component of an operating environment of the device. Verification of the code image may be optional according to the configuration of the key. Secure execution of an unverified code image may be based on a configuration that disables the key.

Abstract: Techniques for intercommunication amongst device drivers are described herein. In one embodiment, an application programming interface (API) is provided by a kernel of an operating system (OS) running within a data processing system. The API is accessible by device drivers associated with multiple devices installed in the system. In response to a request from a first instance of a driver the API, information indicating whether another instance of the same driver is currently started is returned via the API. Other methods and apparatuses are also described.
