Function Documentation

◆ InstallTcgConfigForm()

EFI_STATUS InstallTcgConfigForm ( IN OUT TCG_CONFIG_PRIVATE_DATA * PrivateData )

This function publish the TCG configuration Form for TPM device.

Parameters

[in,out] PrivateData Points to TCG configuration private data.

Return values

EFI_SUCCESS	HII Form is installed for this network device.
EFI_OUT_OF_RESOURCES	Not enough resource for HII Form installation.
Others	Other errors as indicated.

◆ TcgCallback()

EFI_STATUS EFIAPI TcgCallback	(	IN CONST EFI_HII_CONFIG_ACCESS_PROTOCOL *	This,
		IN EFI_BROWSER_ACTION	Action,
		IN EFI_QUESTION_ID	QuestionId,
		IN UINT8	Type,
		IN EFI_IFR_TYPE_VALUE *	Value,
		OUT EFI_BROWSER_ACTION_REQUEST *	ActionRequest
	)

This function processes the results of changes in configuration.

Parameters

[in]	This	Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
[in]	Action	Specifies the type of action taken by the browser.
[in]	QuestionId	A unique value which is sent to the original exporting driver so that it can identify the type of data to expect.
[in]	Type	The type of value for the question.
[in]	Value	A pointer to the data being sent to the original exporting driver.
[out]	ActionRequest	On return, points to the action requested by the callback function.

Return values

EFI_SUCCESS	The callback successfully handled the action.
EFI_OUT_OF_RESOURCES	Not enough storage is available to hold the variable and its data.
EFI_DEVICE_ERROR	The variable could not be saved.
EFI_UNSUPPORTED	The specified Action is not supported by the callback.

◆ TcgExtractConfig()

EFI_STATUS EFIAPI TcgExtractConfig	(	IN CONST EFI_HII_CONFIG_ACCESS_PROTOCOL *	This,
		IN CONST EFI_STRING	Request,
		OUT EFI_STRING *	Progress,
		OUT EFI_STRING *	Results
	)

This function allows a caller to extract the current configuration for one or more named elements from the target driver.

Parameters

[in]	This	Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
[in]	Request	A null-terminated Unicode string in <ConfigRequest> format.
[out]	Progress	On return, points to a character in the Request string. Points to the string's null terminator if request was successful. Points to the most recent '&' before the first failing name/value pair (or the beginning of the string if the failure is in the first name/value pair) if the request was not successful.

◆ TcgRouteConfig()

EFI_STATUS EFIAPI TcgRouteConfig	(	IN CONST EFI_HII_CONFIG_ACCESS_PROTOCOL *	This,
		IN CONST EFI_STRING	Configuration,
		OUT EFI_STRING *	Progress
	)

This function processes the results of changes in configuration.

Parameters

[in]	This	Points to the EFI_HII_CONFIG_ACCESS_PROTOCOL.
[in]	Configuration	A null-terminated Unicode string in <ConfigResp> format.
[out]	Progress	A pointer to a string filled in with the offset of the most recent '&' before the first failing name/value pair (or the beginning of the string if the failure is in the first name/value pair) or the terminating NULL if all was successful.
