Function Documentation

EFI_STATUS EFIAPI EmmcDiskInfoIdentify	(	IN EFI_DISK_INFO_PROTOCOL *	This,
		IN OUT VOID *	IdentifyData,
		IN OUT UINT32 *	IdentifyDataSize
	)

Provides identify information for the controller type.

This function is used by the driver entity to get identify data. Data format of Identify data is defined by the Interface GUID.

Parameters

[in]	This	Pointer to the EFI_DISK_INFO_PROTOCOL instance.
[in,out]	IdentifyData	Pointer to a buffer for the identify data.
[in,out]	IdentifyDataSize	Pointer to the value for the identify data size.

Return values

EFI_SUCCESS	The command was accepted without any errors.
EFI_NOT_FOUND	Device does not support this data class.
EFI_DEVICE_ERROR	Error reading IdentifyData from device.
EFI_BUFFER_TOO_SMALL	IdentifyDataSize not big enough.
