InitializeDiskInfo()

VOID InitializeDiskInfo

(

IN USB_MASS_DEVICE *

UsbMass

)

Initialize the installation of DiskInfo protocol.

This function prepares for the installation of DiskInfo protocol on the child handle. By default, it installs DiskInfo protocol with USB interface GUID.

Parameters

[in]

UsbMass

The pointer of USB_MASS_DEVICE.

Definition at line 29 of file UsbMassDiskInfo.c.

UsbDiskInfoIdentify()

EFI_STATUS EFIAPI UsbDiskInfoIdentify	(	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 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

Definition at line 95 of file UsbMassDiskInfo.c.

UsbDiskInfoInquiry()

EFI_STATUS EFIAPI UsbDiskInfoInquiry	(	IN EFI_DISK_INFO_PROTOCOL *	This,
		IN OUT VOID *	InquiryData,
		IN OUT UINT32 *	InquiryDataSize
	)

Provides inquiry information for the controller type.

This function is used to get inquiry 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]	InquiryData	Pointer to a buffer for the inquiry data.
[in,out]	InquiryDataSize	Pointer to the value for the inquiry 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 InquiryData from device
EFI_BUFFER_TOO_SMALL	InquiryDataSize not big enough

Definition at line 54 of file UsbMassDiskInfo.c.

UsbDiskInfoSenseData()

EFI_STATUS EFIAPI UsbDiskInfoSenseData	(	IN EFI_DISK_INFO_PROTOCOL *	This,
		IN OUT VOID *	SenseData,
		IN OUT UINT32 *	SenseDataSize,
		OUT UINT8 *	SenseDataNumber
	)

Provides sense data information for the controller type.

This function is used to get sense data. Data format of Sense data is defined by the Interface GUID.

Parameters

[in]	This	Pointer to the EFI_DISK_INFO_PROTOCOL instance.
[in,out]	SenseData	Pointer to the SenseData.
[in,out]	SenseDataSize	Size of SenseData in bytes.
[out]	SenseDataNumber	Pointer to the value for the sense 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 SenseData from device.
EFI_BUFFER_TOO_SMALL	SenseDataSize not big enough.

UsbDiskInfoWhichIde()

EFI_STATUS EFIAPI UsbDiskInfoWhichIde	(	IN EFI_DISK_INFO_PROTOCOL *	This,
		OUT UINT32 *	IdeChannel,
		OUT UINT32 *	IdeDevice
	)

This function is used to get controller information.

Parameters

[in]	This	Pointer to the EFI_DISK_INFO_PROTOCOL instance.
[out]	IdeChannel	Pointer to the Ide Channel number. Primary or secondary.
[out]	IdeDevice	Pointer to the Ide Device number. Master or slave.

Return values
