MODIFYING RUN-TIME-INSTRUMENTATION CONTROLS FROM A LESSER-PRIVILEGED STATE |
摘要 |
Embodiments of the invention relate to modifying run-time-instrumentation controls (MRIC) from a lesser-privileged state. The MRIC instruction is fetched. The MRIC instruction includes the address of a run-time-instrumentation control block (RICCB). The RICCB is fetched based on the address included in the MRIC instruction. The RICCB includes values for modifying a subset of the processor's run-time-instrumentation controls. The subset of run-time-instrumentation controls includes a runtime instrumentation program buffer current address (RCA) of a runtime instrumentation program buffer (RIB) location. The RIB holds run-time-instrumentation information of the events recognized by the processor during program execution. The values of the RICCB are loaded into the run-time-instrumentation controls. Event information is provided to the RIB based on the values that were loaded in the run-time-instrumentation control.
