This protocol is used initiate synchronous SMI activations. This protocol could be published by a processor driver to abstract the SMI IPI or a driver which abstracts the ASIC that is supporting the APM port. Because of the possibility of performing SMI IPI transactions, the ability to generate this event from a platform chipset agent is an optional capability for both IA-32 and x64-based systems.
The EFI_SMM_CONTROL2_PROTOCOL is produced by a runtime driver. It provides an abstraction of the platform hardware that generates an SMI. There are often I/O ports that, when accessed, will generate the SMI. Also, the hardware optionally supports the periodic generation of these signals.

Invokes SMI activation from either the preboot or runtime environment.
This function generates an SMI.
[in] | This | The EFI_SMM_CONTROL2_PROTOCOL instance. |
[in,out] | CommandPort | The value written to the command port. |
[in,out] | DataPort | The value written to the data port. |
[in] | Periodic | Optional mechanism to engender a periodic stream. |
[in] | ActivationInterval | Optional parameter to repeat at this period one time or, if the Periodic Boolean is set, periodically. |
EFI_SUCCESS | The SMI/PMI has been engendered. | |
EFI_DEVICE_ERROR | The timing is unsupported. | |
EFI_INVALID_PARAMETER | The activation period is unsupported. | |
EFI_INVALID_PARAMETER | The last periodic activation has not been cleared. | |
EFI_NOT_STARTED | The SMM base service has not been initialized. |

typedef EFI_STATUS(EFIAPI * EFI_SMM_DEACTIVATE2)(IN CONST EFI_SMM_CONTROL2_PROTOCOL *This, IN BOOLEAN Periodic) |
Clears any system state that was created in response to the Trigger() call.
This function acknowledges and causes the deassertion of the SMI activation source.
[in] | This | The EFI_SMM_CONTROL2_PROTOCOL instance. |
[in] | Periodic | Optional parameter to repeat at this period one time |
EFI_SUCCESS | The SMI/PMI has been engendered. | |
EFI_DEVICE_ERROR | The source could not be cleared. | |
EFI_INVALID_PARAMETER | The service did not support the Periodic input argument. |
