摘要： A system and method for avoiding deadlocks when performing storage updates in a multi-processor environment. The system includes a processor having a local cache, a store queue having a temporary buffer with capability to reject exclusive cross-interrogates (XI) while an interrogated cache line is owned exclusive and is to be stored, and a mechanism for performing a method. The method includes setting the processor into a slow mode. A current instruction that includes a data store having one or more target lines is received. The current instruction is executed, with the executing including storing results associated with the data store into the temporary buffer. The store queue is prevented from rejecting an exclusive XI corresponding to the target lines of the current instruction. Each target line is acquired with a status of exclusive ownership, and the contents from the temporary buffer are written to each target line after instruction completion.

摘要： A system, method, and computer program product for handling shared cache lines to allow forward progress among processors in a multi-processor environment is provided. A counter and a threshold are provided a processor of the multi-processor environment, such that the counter is incremented for every exclusive cross interrogate (XI) reject that is followed by an instruction completion, and reset on an exclusive XI acknowledgement. If the XI reject counter reaches a preset threshold value, the processor's pipeline is drained by blocking instruction issue and prefetching attempts, creating a window for an exclusive XI from another processor to be honored, after which normal instruction processing is resumed. Configuring the preset threshold value as a programmable value allows for fine-tuning of system performance.

摘要： A method, system, and computer program product for reduced overhead address mode change management in a pipelined, recycling microprocessor are provided. The recycling microprocessor includes logic executing thereon. The microprocessor also includes an instruction fetch unit (IFU) supporting computation of address adds in selected address modes and reporting non-equal comparison of the computation to the logic. The microprocessor further includes a fixed point unit determining whether the mode has changed and reporting changes to the logic. Upon determining the comparison yields an equal result but the mode has changed, a recycle event is triggered to ensure subsequent ofetches are relaunched in the correct mode and that no execution writebacks occur from work performed in an incorrect mode. For comparisons yielding a non-equal result and a changed mode, the logic clears bits set in response to the determinations, and a serialization event is taken to reset a corresponding pipeline for operation in the correct mode.
