2 This file declares Smm Gpi Smi Child Protocol\r
3 The EFI_SMM_GPI_DISPATCH_PROTOCOL provides the ability to install child handlers for the\r
4 given event types. Several inputs can be enabled. This purpose of this interface is to generate an\r
5 SMI in response to any of these inputs having a true value provided.\r
