◆ COMM_BUFFER_SMM_DISPATCH_ERROR

#define COMM_BUFFER_SMM_DISPATCH_ERROR 0x00

Define values for the communications buffer used when gEfiEventDxeDispatchGuid is event signaled. This event is signaled by the DXE Core each time the DXE Core dispatcher has completed its work. When this event is signaled, the SMM Core if notified, so the SMM Core can dispatch SMM drivers. If COMM_BUFFER_SMM_DISPATCH_ERROR is returned in the communication buffer, then an error occurred dispatching SMM Drivers. If COMM_BUFFER_SMM_DISPATCH_SUCCESS is returned, then the SMM Core dispatched all the drivers it could. If COMM_BUFFER_SMM_DISPATCH_RESTART is returned, then the SMM Core just dispatched the SMM Driver that registered the SMM Entry Point enabling the use of SMM Mode. In this case, the SMM Core should be notified again to dispatch more SMM Drivers using SMM Mode.
