摘要： A method an apparatus for providing capability information to a shared controller. In one embodiment, a peripheral bus host controller may be shared by a plurality of peripheral devices coupled to a peripheral bus. The peripheral devices may include coder/decoder (codec) circuitry, and may be implemented using a riser card. The host controller may be configured to query the bus for peripheral devices by reading each address on the bus. During the querying process, the host controller may detect one or more peripheral devices coupled to the bus. Following the completion of the querying of the bus, the host controller may then begin reading configuration information from each of the detected devices. The host controller may employ one or more of several different techniques in order to read configuration information from the peripheral device. The configuration information at a minimum includes a device identifier, which may identify the vendor and the function of the device. Additional information needed to configure the device to communicate over the peripheral bus may also be obtained with a read of the device, or various lookup mechanisms, such as a lookup table or a tree-like data structure. After configuration information has been obtained for each device coupled to the bus, the host controller may dynamically configure each of the devices for communication over the bus, thereby allowing the flexibility to enumerate riser cards and add new functions through peripheral devices to the computer system in which the bus is implemented.

摘要： The initialization of a computer system including a secure execution mode-capable processor includes storing a secure operating system code segment loader to a plurality of locations corresponding to a particular range of addresses within a system memory. The method also includes executing a security initialization instruction. Executing the security initialization instruction may cause several operations to be performed including transmitting a start transaction including a base address of the particular range of addresses. In addition, executing the security instruction may also cause another operation to be performed including retrieving the secure operating system code segment loader from the system memory and transmitting the secure operating system code segment loader for validation as a plurality of data transactions.

摘要： A method and system for enhanced security and manageability using secure storage. The system may include a crypto-processor and a memory coupled to receive memory transactions through the crypto-processor. The memory transactions are passed to the memory by the crypto-processor. The system may include a first processor, a second processor coupled to the first processor, and a storage device operably coupled to the first processor through the second processor. The second processor is configured to control access to the storage device. The method includes transmitting a request for a memory transaction for a storage location in the storage device and receiving the request for the memory transaction at the crypto-processor. The method also includes determining if the memory transaction is authorized for the storage location, and passing the request for the memory transaction to the storage device if the memory transaction is authorized for the storage location.

摘要： A message based power management approach is utilized to provide power management for a multi-processor system. A power management message is received at one processor of the multi-processor system over an input/output communication link that provides input/output access for the processors of the multi-processor system. The power management message includes a power management field encoding a power management state for processors of the multi-processor system. The processor that received the power management message over the input/output communication link sends a power management message to other processors in the multi-processor system over one or more inter-processor communication links encoding the power management state.

摘要： A diagnosis mechanism for host controllers such as USB (Universal Serial Bus) host controllers is provided. The host controller has a register set that comprises at least one host controller capability register storing data indicative of operational capabilities of the host controller, and at least one host controller operational register storing data for controlling the operation of the host controller. The at least one host controller capability register stores data that is indicative of available diagnostic modes that the host controller can enter. The at least one host controller operational register stores diagnosis data for controlling the operation of the USB host controller in diagnostic modes. This diagnosis mechanism may improve the reliability of the host controller operation.

摘要： A message based power management system converts legacy signals used in power management, and other signals used to differentiate between power states, to messages sent over a communication link. A system message sent on a communication link includes a field encoding the level of power management for the device receiving the system message. Further, one or more additional signals, separate from the communication link, may be used to indicate when to take action after the power management message has been received.

The packet tunnel may convey selected packet transactions between the first and the second transceiver unit. The graphics engine may receive graphics packet transactions from the first transceiver unit and may render digital image information in response to receiving the graphics transactions. The graphics interface may receive additional graphics packet transactions from the first transceiver unit and may translate the additional graphics packet transactions into transactions suitable for transmission upon a graphics bus.
