  • Patent number: 7757081
    Abstract: In one embodiment of the present invention, a method includes verifying an initiating logical processor of a system; validating a trusted agent with the initiating logical processor if the initiating logical processor is verified; and launching the trusted agent on a plurality of processors of the system if the trusted agent is validated. After execution of such a trusted agent, a secure kernel may then be launched, in certain embodiments. The system may be a multiprocessor server system having a partially or fully connected topology with arbitrary point-to-point interconnects, for example.

  • Patent number: 7734741
    Abstract: 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.

  • Publication number: 20090265472
    Abstract: Multiple initialization techniques for system and component in a point-to-point architecture are discussed. Consequently, the techniques allow for flexible system/socket layer parameters to be tailored to the needs of the platform, such as, desktop, mobile, small server, large server, etc., as well as the component types such as IA32/IPF processors, memory controllers, IO Hubs, etc. Furthermore, the techniques facilitate powering up with the correct set of POC values, hence, it avoids multiple warm resets and improves boot time. In one embodiment, registers to hold new values, such as, Configuration Values Driven during Reset (CVDR), and Configuration Values Captured during Reset (CVCR) may be eliminated. For example, the POC values could be from the following: Platform Input Clock to Core Clock Ratio, Enable/disable LT, Configurable Restart, Burn In Initialization Mode, Disable Hyper Threading, System BSP Socket Indication, and Platform Topology Index.

  • Publication number: 20080163331
    Abstract: Apparatuses, methods, and systems for reconfiguring a secure system are disclosed. In one embodiment, an apparatus includes a configuration storage location, a lock, and lock override logic. The configuration storage location is to store information to configure the apparatus. The lock is to prevent writes to the configuration storage location. The lock override logic is to allow instructions executed from sub-operating mode code to override the lock.

  • Patent number: 7328368
    Abstract: 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.

  • Publication number: 20080005346
    Abstract: A separable Transport Layer is described in the context of cache coherent multiple component micro-electronic systems. In one example, a packet is received from a source component, the packet containing a Protocol Layer. A Transport Layer is attached to the packet and the packet is sent across a component communications interface to a second component, the packet containing the Transport Layer and the Protocol Layer.

  • Patent number: 6347362
    Abstract: A flexible event monitoring counter apparatus and process are provided for a processor system including a plurality of nodes, each node having a processor and a portion of a total main memory of the processor system. One example of such a processor system is a Non-Uniform-Memory-Architecture (NUMA) system. In order to reduce the total number of counters necessary, the counter structure will track certain ones of a type of event which occur in the processor system, determined in accordance with a predetermined standard to be most interesting, while discarding other ones of the same type of event determined by the standard to be less interesting. In accordance with one embodiment, the type of event which is tracked or discarded can be page accesses to pages of the total main memory. The standard of most interesting events can be based on the pages which receive the most requests for remote access from a node other than the node where the requested page is located.
