This function retrieves the user readable name of a driver in the form of a
Unicode string. If the driver specified by This has a user readable name in
the language specified by Language, then a pointer to the driver name is
returned in DriverName, and EFI_SUCCESS is returned. If the driver specified
by This does not support the language specified by Language,
then EFI_UNSUPPORTED is returned.
@param This[in] A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
EFI_COMPONENT_NAME_PROTOCOL instance.
@param Language[in] A pointer to a Null-terminated ASCII string
array indicating the language. This is the
language of the driver name 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. Language is specified
in RFC 4646 or ISO 639-2 language code format.
@param DriverName[out] A pointer to the Unicode string to return.
This Unicode string is the name of the

/**
These are the notifications from the PCI bus driver that it is about to enter a certain
phase of the PCI enumeration process.
This member function can be used to notify the host bridge driver to perform specific actions,
including any chipset-specific initialization, so that the chipset is ready to enter the next phase.
Eight notification points are defined at this time. See belows:
EfiPciHostBridgeBeginEnumeration Resets the host bridge PCI apertures and internal data
structures. The PCI enumerator should issue this notification
before starting a fresh enumeration process. Enumeration cannot
be restarted after sending any other notification such as
EfiPciHostBridgeBeginBusAllocation.
EfiPciHostBridgeBeginBusAllocation The bus allocation phase is about to begin. No specific action is
required here. This notification can be used to perform any
chipset-specific programming.
EfiPciHostBridgeEndBusAllocation The bus allocation and bus programming phase is complete. No
specific action is required here. This notification can be used to
perform any chipset-specific programming.
EfiPciHostBridgeBeginResourceAllocation
The resource allocation phase is about to begin. No specific
action is required here. This notification can be used to perform
any chipset-specific programming.
EfiPciHostBridgeAllocateResources Allocates resources per previously submitted requests for all the PCI
root bridges. These resource settings are returned on the next call to
GetProposedResources(). Before calling NotifyPhase() with a Phase of
EfiPciHostBridgeAllocateResource, the PCI bus enumerator is responsible
for gathering I/O and memory requests for
all the PCI root bridges and submitting these requests using
SubmitResources(). This function pads the resource amount
to suit the root bridge hardware, takes care of dependencies between
the PCI root bridges, and calls the Global Coherency Domain (GCD)
with the allocation request. In the case of padding, the allocated range
could be bigger than what was requested.
EfiPciHostBridgeSetResources Programs the host bridge hardware to decode previously allocated
resources (proposed resources) for all the PCI root bridges. After the
hardware is programmed, reassigning resources will not be supported.
The bus settings are not affected.
EfiPciHostBridgeFreeResources Deallocates resources that were previously allocated for all the PCI
root bridges and resets the I/O and memory apertures to their initial
state. The bus settings are not affected. If the request to allocate
resources fails, the PCI enumerator can use this notification to
deallocate previous resources, adjust the requests, and retry
allocation.
EfiPciHostBridgeEndResourceAllocation The resource allocation phase is completed. No specific action is
required here. This notification can be used to perform any chipsetspecific
programming.
@param[in] PciResAlloc The instance pointer of EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
@param[in] Phase The phase during enumeration
@retval EFI_NOT_READY This phase cannot be entered at this time. For example, this error
is valid for a Phase of EfiPciHostBridgeAllocateResources if
SubmitResources() has not been called for one or more
PCI root bridges before this call
@retval EFI_DEVICE_ERROR Programming failed due to a hardware error. This error is valid
for a Phase of EfiPciHostBridgeSetResources.
@retval EFI_INVALID_PARAMETER Invalid phase parameter
@retval EFI_OUT_OF_RESOURCES The request could not be completed due to a lack of resources.
This error is valid for a Phase of EfiPciHostBridgeAllocateResources if the
previously submitted resource requests cannot be fulfilled or
were only partially fulfilled.
@retval EFI_SUCCESS The notification was accepted without any errors.

Returns the allocation attributes of a PCI root bridge.
The function returns the allocation attributes of a specific PCI root bridge. The attributes can vary
from one PCI root bridge to another. These attributes are different from the decode-related
attributes that are returned by the EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL.GetAttributes() member function. The
RootBridgeHandle parameter is used to specify the instance of the PCI root bridge. The device
handles of all the root bridges that are associated with this host bridge must be obtained by calling
GetNextRootBridge(). The attributes are static in the sense that they do not change during or
after the enumeration process. The hardware may provide mechanisms to change the attributes on
the fly, but such changes must be completed before EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL is
installed. The permitted values of EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_ATTRIBUTES are defined in
"Related Definitions" below. The caller uses these attributes to combine multiple resource requests.
For example, if the flag EFI_PCI_HOST_BRIDGE_COMBINE_MEM_PMEM is set, the PCI bus enumerator needs to
include requests for the prefetchable memory in the nonprefetchable memory pool and not request any
prefetchable memory.
Attribute Description
------------------------------------ ----------------------------------------------------------------------
EFI_PCI_HOST_BRIDGE_COMBINE_MEM_PMEM If this bit is set, then the PCI root bridge does not support separate
windows for nonprefetchable and prefetchable memory. A PCI bus
driver needs to include requests for prefetchable memory in the
nonprefetchable memory pool.
EFI_PCI_HOST_BRIDGE_MEM64_DECODE If this bit is set, then the PCI root bridge supports 64-bit memory
windows. If this bit is not set, the PCI bus driver needs to include
requests for a 64-bit memory address in the corresponding 32-bit
memory pool.
@param[in] This The instance pointer of EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
