ABSTRACT:
A processor having one or more processor cores includes execution logic that may execute instructions including one or more processes. Each process may include one or more execution threads. The processor also includes a profiling mechanism that includes monitor logic and a monitor process. The monitor logic may monitor the one or more processes and provide access to performance data associated with the one or more processes without interrupting a flow of control of the one or more processes being monitored. The monitor process may gather the performance data. In addition, the monitor process may include program instructions executable by the one more processor cores while operating in user mode.
