Zusammenfassung:A sample is generated based on an event. Further, an interrupt handler captures information for an interrupted thread on a current processor. In addition, an affinity of the interrupted thread is set such that the interrupted thread runs only on the current processor without being able to migrate to a different processor. A sampler thread that runs on the current processor retrieves a call stack associated with the interrupted thread after the affinity of the interrupted thread has been set to the current processor. The affinity of the interrupted thread is restored after the call stack has been retrieved.
