Module Name:
CirrusLogic5430.c
Abstract:
Cirrus Logic 5430 Controller Driver.
This driver is a sample implementation of the UGA Draw Protocol for the
Cirrus Logic 5430 family of PCI video controllers. This driver is only
usable in the EFI pre-boot environment. This sample is intended to show
how the UGA Draw Protocol is able to function. The UGA I/O Protocol is not
implemented in this sample. A fully compliant EFI UGA driver requires both
the UGA Draw and the UGA I/O Protocol. Please refer to Microsoft's
documentation on UGA for details on how to write a UGA driver that is able
to function both in the EFI pre-boot environment and from the OS runtime.

Arguments:
This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
ControllerHandle - The handle of a controller that the driver specified by
This is managing. This handle specifies the controller
whose name is to be returned.
ChildHandle - The handle of the child controller to retrieve the name
of. This is an optional parameter that may be NULL. It
will be NULL for device drivers. It will also be NULL
for a bus drivers that wish to retrieve the name of the
bus controller. It will not be NULL for a bus driver
that wishes to retrieve the name of a child controller.
Language - A pointer to a three character ISO 639-2 language
identifier. This is the language of the controller name
that that the caller is requesting, and it must match one
of the languages specified in SupportedLanguages. The
number of languages supported by a driver is up to the

that wishes to retrieve the name of a child controller.
Language - A pointer to a three character ISO 639-2 language
identifier. This is the language of the controller name
that that the caller is requesting, and it must match one
of the languages specified in SupportedLanguages. The
number of languages supported by a driver is up to the
driver writer.
ControllerName - A pointer to the Unicode string to return. This Unicode
string is the name of the controller specified by
ControllerHandle and ChildHandle in the language
specified by Language from the point of view of the
driver specified by This.
Returns:
EFI_SUCCESS - The Unicode string for the user readable name in the
language specified by Language for the driver
specified by This was returned in DriverName.
EFI_INVALID_PARAMETER - ControllerHandle is not a valid EFI_HANDLE.
EFI_INVALID_PARAMETER - ChildHandle is not NULL and it is not a valid
EFI_HANDLE.
EFI_INVALID_PARAMETER - Language is NULL.
EFI_INVALID_PARAMETER - ControllerName is NULL.
EFI_UNSUPPORTED - The driver specified by This is not currently
managing the controller specified by
ControllerHandle and ChildHandle.
EFI_UNSUPPORTED - The driver specified by This does not support the
language specified by Language.

Arguments:
This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
ControllerHandle - The handle of a controller that the driver specified by
This is managing. This handle specifies the controller
whose name is to be returned.
ChildHandle - The handle of the child controller to retrieve the name
of. This is an optional parameter that may be NULL. It
will be NULL for device drivers. It will also be NULL
for a bus drivers that wish to retrieve the name of the
bus controller. It will not be NULL for a bus driver
that wishes to retrieve the name of a child controller.
Language - A pointer to a three character ISO 639-2 language
identifier. This is the language of the controller name
that that the caller is requesting, and it must match one
of the languages specified in SupportedLanguages. The
number of languages supported by a driver is up to the

Routine Description:
Sends a SCSI Request Packet to the SCSI Controller for execution.
Arguments:
This - Protocol instance pointer.
Packet - The SCSI request packet to send to the SCSI
Controller specified by the device handle.
Event - If the SCSI bus where the SCSI device is attached
does not support non-blocking I/O, 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 non-blocking I/O is performed,

transferred to/from DataBuffer.See
HostAdapterStatus, TargetStatus,
SenseDataLength, and SenseData in that order
for additional status information.

but the entire DataBuffer could not be transferred.
The actual number of bytes transferred is returned
in TransferLength. See HostAdapterStatus,
TargetStatus, SenseDataLength, and SenseData in
that order for additional status information.
EFI_NOT_READY - The SCSI Request Packet could not be sent because
there are too many SCSI Command Packets already
queued.The caller may retry again later.
EFI_DEVICE_ERROR - A device error occurred while attempting to send
the SCSI Request Packet. See HostAdapterStatus,
TargetStatus, SenseDataLength, and SenseData in
that order for additional status information.
EFI_INVALID_PARAMETER - The contents of CommandPacket are invalid.
The SCSI Request Packet was not sent, so no
additional status information is available.
EFI_UNSUPPORTED - The command described by the SCSI Request Packet
