Detailed Description

This file declares the Smm Gpi Smi Child Protocol.

The EFI_SMM_GPI_DISPATCH_PROTOCOL is defined in Framework of EFI SMM Core Interface Spec Version 0.9. It provides the ability to install child handlers for the given event types. Several inputs can be enabled. This purpose of this interface is to generate an SMI in response to any of these inputs having a true value provided.

Typedef Documentation

typedef VOID(EFIAPI * EFI_SMM_GPI_DISPATCH)(IN EFI_HANDLE DispatchHandle, IN EFI_SMM_GPI_DISPATCH_CONTEXT *DispatchContext)

Dispatch function for a GPI SMI handler.

Parameters:
DispatchHandle The handle of this dispatch function.
DispatchContext The pointer to the dispatch function's context. The DispatchContext fields are filled in by the dispatching driver prior to invoking this dispatch function.

typedef EFI_STATUS(EFIAPI * EFI_SMM_GPI_REGISTER)(IN EFI_SMM_GPI_DISPATCH_PROTOCOL *This, IN EFI_SMM_GPI_DISPATCH DispatchFunction, IN EFI_SMM_GPI_DISPATCH_CONTEXT *DispatchContext, OUT EFI_HANDLE *DispatchHandle)

Register a child SMI source dispatch function with a parent SMM driver

Parameters:
This The pointer to the EFI_SMM_GPI_DISPATCH_PROTOCOL instance.
DispatchFunction Function to install.
DispatchContext The pointer to the dispatch function's context. Indicates to the register function the GPI(s) for which the dispatch function should be invoked.
DispatchHandle The handle generated by the dispatcher to track the function instance.
Return values:
EFI_SUCCESS The dispatch function has been successfully registered, and the SMI source has been enabled.
EFI_DEVICE_ERROR The driver was unable to enable the SMI source.
EFI_OUT_OF_RESOURCES Not enough memory (system or SMM) to manage this child.
EFI_INVALID_PARAMETER DispatchContext is invalid. The GPI input value is not within valid range.

typedef EFI_STATUS(EFIAPI * EFI_SMM_GPI_UNREGISTER)(IN EFI_SMM_GPI_DISPATCH_PROTOCOL *This, IN EFI_HANDLE DispatchHandle)

Unregisters a General Purpose Input (GPI) service.

Parameters:
This The pointer to the EFI_SMM_GPI_DISPATCH_PROTOCOL instance.
DispatchHandle The handle of the service to remove.
Return values:
EFI_SUCCESS The dispatch function has been successfully unregistered, and the SMI source has been disabled, if there are no other registered child dispatch functions for this SMI source.
EFI_INVALID_PARAMETER DispatchHandle is invalid.
