	)

Flush the Block Device.

If EFI_DEVICE_ERROR, EFI_NO_MEDIA,_EFI_WRITE_PROTECTED or EFI_MEDIA_CHANGED is returned and non-blocking I/O is being used, the Event associated with this request will not be signaled.

Parameters

[in]	This	Indicates a pointer to the calling context.
[in,out]	Token	A pointer to the token associated with the transaction

Return values

EFI_SUCCESS	The flush request was queued if Event is not NULL. All outstanding data was written correctly to the device if the Event is NULL.
EFI_DEVICE_ERROR	The device reported an error while writing back the data.
EFI_WRITE_PROTECTED	The device cannot be written to.
EFI_NO_MEDIA	There is no media in the device.
EFI_MEDIA_CHANGED	The MediaId is not for the current media.
EFI_OUT_OF_RESOURCES	The request could not be completed due to a lack of resources.

		IN UINTN	BufferSize,
		OUT VOID *	Buffer
	)

Read BufferSize bytes from Lba into Buffer.

This function reads the requested number of blocks from the device. All the blocks are read, or an error is returned. If EFI_DEVICE_ERROR, EFI_NO_MEDIA,_or EFI_MEDIA_CHANGED is returned and non-blocking I/O is being used, the Event associated with this request will not be signaled.

Parameters

[in]	This	Indicates a pointer to the calling context.
[in]	MediaId	Id of the media, changes every time the media is replaced.
[in]	Lba	The starting Logical Block Address to read from.
[in,out]	Token	A pointer to the token associated with the transaction.
[in]	BufferSize	Size of Buffer, must be a multiple of device block size.
[out]	Buffer	A pointer to the destination buffer for the data. The caller is responsible for either having implicit or explicit ownership of the buffer.

Return values

EFI_SUCCESS	The read request was queued if Token->Event is not NULL.The data was read correctly from the device if the Token->Event is NULL.
EFI_DEVICE_ERROR	The device reported an error while performing the read.
EFI_NO_MEDIA	There is no media in the device.
EFI_MEDIA_CHANGED	The MediaId is not for the current media.
EFI_BAD_BUFFER_SIZE	The BufferSize parameter is not a multiple of the intrinsic block size of the device.
EFI_INVALID_PARAMETER	The read request contains LBAs that are not valid, or the buffer is not on proper alignment.
EFI_OUT_OF_RESOURCES	The request could not be completed due to a lack of resources.

	)

Reset the block device hardware.

Parameters

[in]	This	Indicates a pointer to the calling context.
[in]	ExtendedVerification	Indicates that the driver may perform a more exhausive verfication operation of the device during reset.

Return values

EFI_SUCCESS	The device was reset.
EFI_DEVICE_ERROR	The device is not functioning properly and could not be reset.

		IN UINT32	MediaId,
		IN EFI_LBA	Lba,
		IN OUT EFI_BLOCK_IO2_TOKEN *	Token,
		IN UINTN	BufferSize,
		IN VOID *	Buffer
	)

Write BufferSize bytes from Lba into Buffer.

This function writes the requested number of blocks to the device. All blocks are written, or an error is returned.If EFI_DEVICE_ERROR, EFI_NO_MEDIA, EFI_WRITE_PROTECTED or EFI_MEDIA_CHANGED is returned and non-blocking I/O is being used, the Event associated with this request will not be signaled.

Parameters

[in]	This	Indicates a pointer to the calling context.
[in]	MediaId	The media ID that the write request is for.
[in]	Lba	The starting logical block address to be written. The caller is responsible for writing to only legitimate locations.
[in,out]	Token	A pointer to the token associated with the transaction.
[in]	BufferSize	Size of Buffer, must be a multiple of device block size.
[in]	Buffer	A pointer to the source buffer for the data.

Return values

EFI_SUCCESS	The write request was queued if Event is not NULL. The data was written correctly to the device if the Event is NULL.
EFI_WRITE_PROTECTED	The device can not be written to.
EFI_NO_MEDIA	There is no media in the device.
EFI_MEDIA_CHANGED	The MediaId does not match the current device.
EFI_DEVICE_ERROR	The device reported an error while performing the write.
EFI_BAD_BUFFER_SIZE	The Buffer was not a multiple of the block size of the device.
EFI_INVALID_PARAMETER	The write request contains LBAs that are not valid, or the buffer is not on proper alignment.
EFI_OUT_OF_RESOURCES	The request could not be completed due to a lack of resources.
