RUN-TIME INSTRUMENTATION REPORTING
First Claim
1. A computer implemented method for run-time instrumentation reporting, the method comprising:
- executing an instruction stream by a processor;
capturing, by the processor, run-time instrumentation information of said executing instruction stream;
based on said captured run-time instrumentation information, creating run-time instrumentation records;
detecting a run-time instrumentation sample point of the executing instruction stream on the processor; and
storing a reporting group in a run-time instrumentation program buffer, the storing based on the detecting a run-time instrumentation sample point, the storing comprising;
determining a current address of the run-time instrumentation program buffer, the determining based on instruction accessible run-time instrumentation controls; and
storing the reporting group into the run-time instrumentation program buffer based on an origin address and the current address of the run-time instrumentation program buffer, the reporting group comprising said created run-time instrumentation records.

Abstract
Embodiments of the invention relate to run-time instrumentation reporting. An instruction stream is executed by a processor. Run-time instrumentation information of the executing instruction stream is captured by the processor. Run-time instrumentation records are created based on the captured run-time instrumentation information. A run-time instrumentation sample point of the executing instruction stream on the processor is detected. A reporting group is stored in a run-time instrumentation program buffer. The storing is based on the detecting and the storing includes: determining a current address of the run-time instrumentation program buffer, the determining based on instruction accessible run-time instrumentation controls; and storing the reporting group into the run-time instrumentation program buffer based on an origin address and the current address of the run-time instrumentation program buffer, the reporting group including the created run-time instrumentation records.
