Instruction and logic for interrupt and exception handling

A processor includes a processor trace logical unit to produce branch execution records from execution of instructions. The processor further includes logic to determine that a condition has occurred on the processor during execution of the instructions. The condition is to include an asynchronous e...

Zusammenfassung:A processor includes a processor trace logical unit to produce branch execution records from execution of instructions. The processor further includes logic to determine that a condition has occurred on the processor during execution of the instructions. The condition is to include an asynchronous event or a return from a software handler for an asynchronous event. The processor further includes logic to determine whether event tracing is enabled for the processor. The processor also includes logic to generate a control flow event (CFE) packet. The CFE packet is to indicate a type of the condition. The processor further includes logic to generate an indicator of an instruction address that generated the condition.
