TEMPORARY PIPELINE MARKING FOR PROCESSOR ERROR WORKAROUNDS

摘要

Embodiments include a method for temporary pipeline marking for processor error workarounds. The method includes monitoring a pipeline of a processor for an event that is predetermined to place the processor in a stuck state that results in an errant instruction execution result due to the stuck state or repeated resource contention causing performance degradation. The pipeline is marked for a workaround action based on detecting the event. A clearing action is triggered based on the marking of the pipeline. The marking of the pipeline is cleared based on the triggering of the clearing action.

1. A method for temporary pipeline marking for processor error workarounds, the method comprising:
monitoring a pipeline of a processor for an event that is predetermined to: cause a stuck state that results in an errant instruction execution result due to the stuck state or a repeated resource contention causing a performance degradation; marking the pipeline for a workaround action based on detecting the event; triggering a clearing action based on the marking of the pipeline; and clearing the marking of the pipeline based on the triggering of the clearing action.
