Monitoring Performance of a Processing Device to Manage Non-Precise Events

摘要

In accordance with embodiments disclosed herein, there is provided systems and methods for monitoring performance of a processing device to manage non-precise events. A processing device includes a performance counter to increment upon occurrence of a non-precise event in the processing device. The processing device also includes a precise event based sampling (PEBS) enable control communicably coupled to the performance counter. The processing device also includes a PEBS handler to generate and store a PEBS record including an architectural metadata defining a state of the processing device at a time of generation of the PEBS record. The processing device further includes a non-precise event based sampling (NPEBS) module communicably coupled to the PEBS control and the PEBS handler. The NPEBS module causes the PEBS handler to generate the PEBS record for the non-precise event upon overflow of the performance counter.
