摘要:
In some embodiments an apparatus includes a transmission error detector to detect an error of a transmission of an interconnect and a transmitting agent to retry the transmission in response to the detected error. The apparatus also includes a hard failure detector to detect a hard failure of the interconnect if the retry is unsuccessful, and a transmission width reducer to reduce a transmission width of the interconnect in response to the hard failure detector. Other embodiments are described and claimed.

A method is described that involves directing a configuration request through a switch core to a configuration agent. The method also involves processing the configuration request at the configuration agent. The method also involves sending a configuration command derived from the configuration request from the configuration agent to the switch core. The method also involves executing the configuration command at an agent to which the configuration command pertains.

Embodiments of the present invention relate to methods and apparatus for managing transaction requests in a multi-node architecture. In one embodiment, a previously received ordered group request may be forwarded to a destination agent. Whether a next received ordered group request belongs to a same ordered group as the previously received ordered group request may be determined. Additionally, it may be determined whether an ordering fork is encountered if the next received ordered group request belongs to the same ordered group as the previously received ordered group request. If an ordering fork is encountered, it may be determined whether a request complete message for the previously received ordered group request has been received. If the request complete message for the previously received ordered group request has not been received and the next received ordered group request in the same ordered group is at least one of a un-ordered request and a forward-ordered request, then the next received ordered group request may be forwarded to the destination agent after the request complete message for the previously received at least one of a forward-ordered request and a sequential-ordered request issued on a different path at the ordering fork has been received.

A dynamic reconfiguration to include on-line addition, deletion, and replacement of individual modules of to support dynamic partitioning of a system, interconnect (link) reconfiguration, memory RAS to allow migration and mirroring without OS intervention, dynamic memory reinterleaving, CPU and socket migration, and support for global shared memory across partitions is described. To facilitate the on-line addition or deletion, the firmware is able to quiesce and de-quiesce the domain of interest so that many system resources, such as routing tables and address decoders, can be updated in what essentially appears to be an atomic operation to the software layer above the firmware.

A method, chip multiprocessor tile, and a chip multiprocessor with amorphous caching are disclosed. An initial processing core 404 may retrieve a data block from a data storage. An initial amorphous cache bank 410 adjacent to the initial processing core 404 may store an initial data block copy 422. A home bank directory 424 may register the initial data block copy 422.

An embodiment of the present invention is a technique to process system management interrupt. A system management interrupt (SMI) is received. The SMI is associated with a system management mode (SMM). A conditional SMI inter-processor interrupt (IPI) message is broadcast to at least a processor. The SMI is processed without waiting for the at least processor to check into the SMM. A clear pending SMI is broadcast to the processors at end of SMI processing to clear a pending SMI condition.

An embodiment of the present invention is a technique to enhance address translation performance. A register stores capability indicators to indicate capability supported by a circuit in a chipset for address translation of a guest physical address to a host physical address. A plurality of multi-level page tables is used for page walking in the address translation. Each of the page tables has page table entries. Each of the page table entries has at least an entry specifier corresponding to the capability indicated by the capability indicators.
