Routine Description:
Retrieves a Unicode string that is the user readable name of the controller
that is being managed by an EFI Driver.
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:
Retrieves a Unicode string that is the user readable name of the EFI Driver.
Arguments:
This - A pointer to the EFI_COMPONENT_NAME_PROTOCOL instance.
Language - A pointer to a three character ISO 639-2 language identifier.
This is the language of the driver 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.
DriverName - A pointer to the Unicode string to return. This Unicode string
is the name of the driver specified by This in the language
specified by Language.
Returns:
EFI_SUCCESS - The Unicode string for the Driver specified by This
and the language specified by Language was returned
in DriverName.
EFI_INVALID_PARAMETER - Language is NULL.
EFI_INVALID_PARAMETER - DriverName is NULL.
EFI_UNSUPPORTED - The driver specified by This does not support the

Routine Description:
Retrieves a Unicode string that is the user readable name of the controller
that is being managed by an EFI Driver.
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
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

Arguments:
This - The EFI_DATA_HUB_PROTOCOL instance.
MonotonicCount - Specifies the Record to return. On input, zero means
return the first record. On output, contains the next
record to availible. Zero indicates no more records.
FilterDriverEvent - If FilterDriverEvent is not passed in a MonotonicCount
of zero, it means to return the first data record.
If FilterDriverEvent is passed in, then a MonotonicCount
of zero means to return the first data not yet read by

)
/*++
Routine Description:
This function registers the data hub filter driver that is represented
by FilterEvent. Only one instance of each FilterEvent can be registered.
After the FilterEvent is registered, it will be signaled so it can sync
with data records that have been recorded prior to the FilterEvent being
registered.
Arguments:
This - The EFI_DATA_HUB_PROTOCOL instance.
FilterEvent - The EFI_EVENT to signal whenever data that matches
FilterClass is logged in the system.
FilterTpl - The maximum EFI_TPL at which FilterEvent can be
signaled. It is strongly recommended that you use the
lowest EFI_TPL possible.
FilterClass - FilterEvent will be signaled whenever a bit in
EFI_DATA_RECORD_HEADER.DataRecordClass is also set in
FilterClass. If FilterClass is zero, no class-based
filtering will be performed.
FilterDataRecordGuid - FilterEvent will be signaled whenever FilterDataRecordGuid
matches EFI_DATA_RECORD_HEADER.DataRecordGuid. If
FilterDataRecordGuid is NULL, then no GUID-based filtering

Module Name:
DiskIo.c
Abstract:
DiskIo driver that layers it's self on every Block IO protocol in the system.
DiskIo converts a block oriented device to a byte oriented device.
ReadDisk may have to do reads that are not aligned on sector boundaries.
There are three cases:
UnderRun - The first byte is not on a sector boundary or the read request is
less than a sector in length.
Aligned - A read of N contiguous sectors.
OverRun - The last byte is not on a sector boundary.

Abstract:
Decode a hard disk partitioned with the legacy MBR found on most PC's
MBR - Master Boot Record is in the first sector of a partitioned hard disk.
The MBR supports four partitions per disk. The MBR also contains legacy
code that is not run on an EFI system. The legacy code reads the
first sector of the active partition into memory and
BPB - Boot(?) Parameter Block is in the first sector of a FAT file system.
The BPB contains information about the FAT file system. The BPB is
always on the first sector of a media. The first sector also contains
the legacy boot strap code.

track of any resource allocations performed in loading and
executing the image.
EbcEntryPoint - the entry point for the image (as defined in the file header)

Routine Description:
This function is called to execute an EBC CALLEX instruction.
The function check the callee's content to see whether it is common native
code or a thunk to another piece of EBC code.
If the callee is common native code, use EbcLLCAllEXASM to manipulate,
otherwise, set the VM->IP to target EBC code directly to avoid another VM
be startup which cost time and stack space.
Arguments:
VmPtr - Pointer to a VM context.
FuncAddr - Callee's address
NewStackPointer - New stack pointer after the call
FramePtr - New frame pointer after the call
Size - The size of call instruction
Returns:
None.
