摘要： Mechanisms, in a multi-chip data processing system, for performing a boot process for booting each of a plurality of processor chips of the multi-chip data processing system are provided. With these mechanisms, a multi-chip agnostic isolated boot phase operation is performed, in parallel, to perform an initial boot of each of the plurality of processor chips as if each of the processor chips were an only processor chip in the multi-chip data processing system. A multi-chip aware isolated boot phase operation of each of the processor chips is performed in parallel, where each of the processor chips has its own separately configured address space. In addition, a unified configuration phase operation is performed to select a master processor chip from the plurality of processor chips and configure other processor chips in the plurality of processor chips to operate as slave processor chips that are controlled by the master processor chip.

摘要： Integrating link calibration and dynamic topology discovery in a multi-processor system establishes a first of a plurality of processors in the multi-processor system as a director of integrated link calibration and dynamic topology discovery. A plurality of high speed interconnects connects the plurality of processors with each other. The director processor directs calibration of each of the plurality of high speed interconnects via a shared hardware resource. The shared hardware resource is shared among the plurality of processors. Topology of the multi-processor system is incrementally discovered as each of the plurality of high speed interconnects is calibrated based on a result of each of the plurality of high speed interconnects being calibrated.

摘要： A system and associated method for block ciphering. The method generates a key that is specific to a text block being encrypted and later being decrypted. The text block is encrypted by a block cipher encryption with the key. The encrypted text block is decrypted by a block cipher decryption with the key back to the text block. Altering a single bit in either the encrypted text block or the key results in unsuccessful decryption such that a decrypted text block is completely different from the before encryption.

摘要： A method provides exception handling for a computer system. As an error in the computer system's hardware is detected, an exception vector pertaining to the hardware error is determined, and execution flow is transferred to a dispatcher that corresponds/pertains to the exception vector. A specific instance of a plurality of instances of a main exception handler is selected, and the specific instance of the main exception handler is executed. The actual exception handler thus contains two distinct parts, a dispatcher, which is unique and preferably resides in a safe memory region, and a main exception handler, multiple copies of which reside in an unsafe memory region.
