Tests to see if this driver supports a given controller. If a child device is provided,
it tests to see if this driver supports creating a handle for the specified child device.
This function checks to see if the driver specified by This supports the device specified by
ControllerHandle. Drivers typically use the device path attached to
ControllerHandle and/or the services from the bus I/O abstraction attached to
ControllerHandle to determine if the driver supports ControllerHandle. This function
may be called many times during platform initialization. In order to reduce boot times, the tests
performed by this function must be very small and take as little time as possible to execute. This
function must not change the state of any hardware devices, and this function must be aware that the
device specified by ControllerHandle may already be managed by the same driver or a
different driver. This function must match its calls to AllocatePages() with FreePages(),
AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
Since ControllerHandle may have been previously started by the same driver, if a protocol is
already in the opened state, then it must not be closed with CloseProtocol(). This is required
to guarantee the state of ControllerHandle is not modified by this function.
@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
@param[in] ControllerHandle The handle of the controller to test. This handle
must support a protocol interface that supplies
an I/O abstraction to the driver.
@param[in] RemainingDevicePath A pointer to the remaining portion of a device path. This
parameter is ignored by device drivers, and is optional for bus
drivers. For bus drivers, if this parameter is not NULL, then
the bus driver must determine if the bus controller specified
by ControllerHandle and the child controller specified
by RemainingDevicePath are both supported by this
bus driver.
@retval EFI_SUCCESS The device specified by ControllerHandle and
RemainingDevicePath is supported by the driver specified by This.
@retval EFI_ALREADY_STARTED The device specified by ControllerHandle and
RemainingDevicePath is already managed by the driver
specified by This.
@retval EFI_ACCESS_DENIED The device specified by ControllerHandle and
RemainingDevicePath is already managed by a different
driver or an application that requires exclusive access.

@retval EFI_UNSUPPORTED The device specified by ControllerHandle and

/**
Sends a SCSI Request Packet to a SCSI device that is attached to the SCSI channel.
This function supports both blocking I/O and nonblocking I/O. The blocking I/O
functionality is required, and the nonblocking I/O functionality is optional.
@param[in] This A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.
@param[in] Target The Target is an array of size TARGET_MAX_BYTES and it
represents the id of the SCSI device to send the SCSI
Request Packet. Each transport driver may choose to
utilize a subset of this size to suit the needs
of transport target representation. For example, a
Fibre Channel driver may use only 8 bytes (WWN)
to represent an FC target.
@param[in] Lun The LUN of the SCSI device to send the SCSI Request Packet.
@param[in, out] Packet A pointer to the SCSI Request Packet to send to the
SCSI device specified by Target and Lun.
@param[in] Event If nonblocking I/O is not supported then Event is ignored,
and blocking I/O is performed. If Event is NULL, then
blocking I/O is performed. If Event is not NULL and non
blocking I/O is supported, then nonblocking I/O is performed,
and Event will be signaled when the SCSI Request Packet
completes.
@retval EFI_SUCCESS The SCSI Request Packet was sent by the host. For
bi-directional commands, InTransferLength bytes
were transferred from InDataBuffer.
For write and bi-directional commands, OutTransferLength
bytes were transferred by OutDataBuffer.
@retval EFI_BAD_BUFFER_SIZE The SCSI Request Packet was not executed.
The number of bytes that could be transferred is
returned in InTransferLength. For write and
bi-directional commands, OutTransferLength bytes
were transferred by OutDataBuffer.
@retval EFI_NOT_READY The SCSI Request Packet could not be sent because
there are too many SCSI Request Packets already
queued. The caller may retry later.
@retval EFI_DEVICE_ERROR A device error occurred while attempting to send
the SCSI Request Packet.
@retval EFI_INVALID_PARAMETER Target, Lun, or the contents of ScsiRequestPacket
are invalid.
@retval EFI_UNSUPPORTED The command described by the SCSI Request Packet
is not supported by the host adapter.
This includes the case of Bi-directional SCSI
commands not supported by the implementation.
The SCSI Request Packet was not sent,
so no additional status information is available.
@retval EFI_TIMEOUT A timeout occurred while waiting for the SCSI
Request Packet to execute.
