Abstract: Register operations to cause a processor unit to enter into a management operating mode are stored in a dedicated buffer in the processor unit and are executed by the processor unit when the processor unit is to enter into a management operating mode. The register operations can be stored in the buffer during computing system startup or by out-of-band provisioning during computing system runtime. The register operations can save a state of the processor unit as part of entering the management operating mode and restore the state when the processor unit exits the management operation mode. In computing systems comprising multiple processor units, the register operations can cause one of the processor units to execute management operating mode instructions and one or more other processor units to enter into an idle mode while the processor units are in the management operating mode.
