    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: Techniques for associating device drivers via a device tree are described herein. In one embodiment, a device tree having a hierarchical structure is maintained by a kernel of an operating system. The device tree includes device nodes corresponding to devices installed in a computer, including a first node and a second node. An auxiliary driver identifier is encoded within the first node for identifying a second device driver associated with the second node. The auxiliary driver identifier is used by a first device driver associated with the first node to invoke the second device driver to perform a predetermined operation on a device associated with the first node. Other methods and apparatuses are also described.

    Abstract: A process and apparatus for configuring one or more integrated circuits within a device in a manufacturing process is described. In an exemplary process, a device is manufactured by assembling a chip onto a board such as a printed circuit substrate and the chip is fused from power routed across the board to the chip. The power source for the fusing can be generated from the internal power supply on the board or received on a test point on the board itself or a connection interface (e.g. a USB interface) coupled to the board. In an exemplary apparatus, a device comprises a chip with a plurality of fuses that are used to configure the device and a board coupled to the chip, with the board capable of routing power from the board to the chip and the power is used to blow one or more of the plurality of fuses.

    Abstract: A method and apparatus for personalizing a software component to be executed in particular environment are described herein. According to an aspect of the invention, in response to an executable code image representing a software component to be installed in an electronic device, the executable code image is encrypted using an encryption key. The encryption key is then wrapped with a UID that uniquely identifies the electronic device, where the UID is embedded within a secure ROM of the electronic device. The wrapped encryption key and the encrypted executable code image are then encapsulated into a data object to be stored in a storage of the electronic device, such that when the electronic device is subsequently initialized for operation, the executable code image can only be recovered using the UID of the electronic device to retrieve a decryption key in order to decrypt the executable code image.

    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.
