摘要： A method for initializing a computing system comprising a plurality of devices which communicate on a communication link comprising a plurality of independent point-to-point links is provided, each of the point-to-point links interconnecting a respective pair of the plurality of devices. The method includes a link initialization procedure comprising initially configuring each respective pair of devices to communicate on the respective interconnecting link using common communication parameters, including a common frequency and a common link width. The link initialization procedure also may include an optimization procedure for determining maximum communication parameters for each interconnected pair of devices. If the maximum compatible parameters differ from the common parameters for any pair of devices, then the pair of devices may be reconfigured to communicate on the interconnecting link using the maximum compatible parameters. Once a communication capability has been established, the establishment of one or more communication fabrics for the computer system may be performed. This scheme includes designating a bootstrap processor, locating the boot ROM, establishing the manner in which the devices are interconnected, and defining routing directions for routing communications among the various devices in the computing system.

摘要： A messaging scheme to synchronize processes within a distributed memory multiprocessing computer system having two or more processing nodes interconnected using an interconnect structure of dual-unidirectional links. Each unidirectional link forms a point-to-point interconnect to transfer packetized information between two processing nodes. A lock acquisition request from a lock requesting node is placed into service by an arbitrating node when no previous lock requests are pending for service. The arbitrating node transmits a broadcast message to all nodes in the system, which, in turn, respond with a corresponding probe response message to inform the arbitrating node of cessation of issuance of new requests by the node sending the probe response message. The arbitrating node informs the lock requesting node of the requesting node's lock ownership by transmitting a target done message thereto. After completion of lock operations, the lock requesting node sends a lock release request to the arbitrating node, which, in turn, informs all processing nodes of lock release by transmitting another broadcast message within the system. The messaging protocol is completed when each node sends another probe response to the arbitrating node, which, in turn, sends a final target done message to the lock requesting node. Lock operations are performed without contention for system resources and without deadlocks among various processing nodes.

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 method and apparatus to allow program steps in an issue queue to be sent to the execution queue in a non program order provides reduced stall by allowing out of program order steps to be executed as needed resources become available. The method uses a modulus operation to preassign locations in the execution queues, and keep the entries in proper program order. The method employs an additional bit to represent the modules result (value) and may also utilize a load store number mapping memory to increase execution speed. With such an arrangement a computer system may decrease the lost performance due to waiting for required resource (i.e., memory or bus) availability for the current instruction, by issuing instructions for which the memory or bus resource is available even though the instruction is not the next one in the original program order. Thus the present invention allows memory reference instructions to issue as resources are available.

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.

摘要： A system and method for inputting a set of values, e.g. an operating frequency, using dual-use signal connections. In an exemplary computer system, one or more processors are each coupled to a bridge. The dual-use signal connections are used to input an operating frequency ratio to a processor. The operating frequency ratio may also be input to the bridge. Once the operation of the processor has been initialized, the dual-use signal connections may be used to output operating parameters of the processor. The use of the using dual-use signal connections may advantageously allow for the operating frequency ratio to be input to the processor without dedicated signal lines or pins.
