    Abstract: Systems and method are disclosed for monitoring processor performance. Embodiments described relate to differentiating function performance by input parameters. In one embodiment, a method includes configuring a counter contained in a processor to count occurrences of an event in the processor and to overflow upon the count of occurrences reaching a specified value, configuring a precise event based sampling (PEBS) handler circuit to generate and store a PEBS record into a PEBS memory buffer after at least one overflow, the PEBS record containing at least one stack entry read from a stack after the at least one overflow, enabling the PEBS handler circuit to generate and store the PEBS record after the at least one overflow, generating and storing the PEBS record into the PEBS memory buffer after the at least one overflow; and storing contents of the PEBS memory buffer to a PEBS trace file in a memory.

    Abstract: A processor is to execute and retire instructions for a virtual machine. A reload register is coupled to the core is to store a reload value. A performance monitoring counter (PMC) register is coupled to the reload register and an event-based sampler operatively is coupled to the reload register and the PMC register. The event-based sampler includes circuitry to load the reload value into the PMC register and increment the PMC register after detecting each occurrence of an event of a certain type as a result of execution of the instructions. Upon detecting an occurrence of the event after the PMC register reaches a predetermined trigger value, the event-based sampler is to execute microcode to generate field data for elements within a sampling record, wherein the field data relates to a current processor state of execution, and reload the reload value from the reload register into the PMC register.
