An embodiment of the present invention is a technique to process system
management interrupt. A system management interrupt (SMI) is received.
The SMI is associated with a system management mode (SMM). A conditional
SMI inter-processor interrupt (IPI) message is broadcast to at least a
processor. The SMI is processed without waiting for the at least
processor to check into the SMM. A clear pending SMI is broadcast to the
processors at end of SMI processing to clear a pending SMI condition.
