  • Patent number: 9842015
    Abstract: A processor includes a logic to determine an error condition reported in an error bank. The error bank is communicatively coupled to the processor and is associated with logical processors of the processor. The processor includes another logic to generate an interrupt indicating the error condition. The processor includes yet another logic to selectively send the interrupt to a single one of the logical processors associated with the error bank.

  • Patent number: 9798556
    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.

  • Patent number: 9317360
    Abstract: In some implementations, a processor may include a machine check architecture having a plurality of error reporting registers able to receive data for machine check errors. A summary register may include a plurality of settable locations that each represents at least one of the error reporting registers. One or more of the settable locations in the summary register may be set to indicate whether one or more of the error reporting registers maintain data for a machine check error. Accordingly, when a machine check error occurs, the summary register may be accessed to identify if any error reporting registers in a processor's view contain valid error data, rather than having to read each of the error reporting registers in the processor's view.

  • Patent number: 9150972
    Abstract: Disclosed is a Fuel Augmentation Support System (“FASS”). The disclosed FASS herein is useful to support a multitude of electrolysis cell composition and designs. It provides a system which supports an uncontaminated electrolysis process via the prohibition of other elements from intermingling with the electrolytic fluid, without creating excess positive or negative pressures in a FASS operations, an example of producing gas using the electrolysis of distilled water combined with a catalyst of potassium Hydroxide will be used since it is a method to generate a combustible gas used to enhance the combustion of practically any fuel. The FASS exploits an efficient utilization of electrons generated between the electrolysis electrodes in order to produce gas and achieve it's goals.
