Zusammenfassung:Systems, methods, and devices are provided for identification of model-specific behavior relating to microcode update capabilities of a processor to enable efficient microcode updates across a range of different machines. A system may include a first processor core and a second processor core. A register of the system may indicate a hardware capability of the system to perform a uniform microcode update by propagating a microcode update from the first processor core to a second processor core.
