Abstract: The invention relates to determining the status of run-time-instrumentation controls. The status is determined by executing a test run-time-instrumentation controls (TRIC) instruction. The TRIC instruction is executed in either a supervisor state or a lesser-privileged state. The TRIC instruction determines whether the run-time-instrumentation controls have changed. The run-time-instrumentation controls are set to an initial value using a privileged load run-time-instrumentation controls (LRIC) instruction. The TRIC instruction is fetched and executed. If the TRIC instruction is enabled, then it is determined if the initial value set by the run-time-instrumentation controls has been changed. If the initial value set by the run-time-instrumentation controls has been changed, then a condition code is set to a first value.

Abstract: An aspect includes 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.
