Abstract
Mechanisms for providing enhanced system performance and reliability on multi-core computing devices are discussed. Embodiments use modified hardware and/or software so that when a System Management Interrupt (SMI #) is generated, only a single targeted CPU core enters System Management Mode (SMM) in response to the SMI while the remaining CPU cores continue operating in normal mode. Further, a multi-threaded SMM environment and mutual exclusion objects (mutexes) may allow guarding of key hardware resources and software data structures to enable individual CPU cores among the remaining CPU cores to subsequently also enter SMM in response to a different SMI while the originally selected CPU core is still in SMM.
