    Abstract: A method and apparatus for securely booting software components in an electronic device to establish an operating environment are described herein. According to an aspect of the invention, software components are to be executed in sequence in order to establish an operating environment of a device. For each software component, a security code is executed to authenticate and verify an executable code image associated with each software component using one or more keys embedded within a secure ROM (read-only memory) of the device and one or more hardware configuration settings of the device. The security code for each software component includes a common functionality to authenticate and verify the executable code image associated with each software component. In response to successfully authenticating and verifying the executable code image, the executable code image is then executed in a main memory of the device to launch the associated software component.

    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.

    Abstract: A method and apparatus for executing a first executable code image having a first version number into a memory of a device in an attempt to establish an operating environment of the device are described. The first executable code image retrieves a second version number from the second executable code image after successfully authenticating the second executable code image. If the first version number and the second version number do not satisfy a predetermined relationship, the second executable code image is prevented from being loaded by the first executable code image.

    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 via 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.
