- is useful in the case of drives that lie about their capabilities. An example
- is when the IDE device fails to accept the timing modes that are calculated
- by the IDE controller driver based on the response to the Identify Drive command.
-
- If the driver entity does not want to limit the ATA timing modes and leave that

- is the pointer to the response data buffer. The IdentifyData buffer is owned
- by the driver entity, and the IDE controller driver must make a local copy
- of the entire buffer or parts of the buffer as needed. The original IdentifyData

- may examine the vendor and type/mode field to match known bad drives.

- Disqualifies specific modes for an IDE device.
-
- This function allows the driver entity or other drivers (such as platform
- drivers) to reject certain timing modes and request the IDE controller driver
- to recalculate modes. This function allows the driver entity and the IDE
- controller driver to negotiate the timings on a per-device basis. This function
- is useful in the case of drives that lie about their capabilities. An example
- is when the IDE device fails to accept the timing modes that are calculated
- by the IDE controller driver based on the response to the Identify Drive command.
-
- If the driver entity does not want to limit the ATA timing modes and leave that
- decision to the IDE controller driver, it can either not call this function for
- the given device or call this function and set the Valid flag to FALSE for all
- modes that are listed in EFI_ATA_COLLECTIVE_MODE.
-
- The driver entity may disqualify modes for a device in any order and any number
- of times.
-
- This function can be called multiple times to invalidate multiple modes of the
- same type (e.g., Programmed Input/Output [PIO] modes 3 and 4). See the ATA/ATAPI
- specification for more information on PIO modes.
-
- For Serial ATA (SATA) controllers, this member function can be used to disqualify

-/**
- 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] This 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.

- 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

- "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
-
- @param[in] RootBridgeHandle The device handle of the PCI root bridge in
- which the caller is interested. Type
- EFI_HANDLE is defined in
- InstallProtocolInterface() in the UEFI 2.0
- Specification.
-
- @param[out] Attributes The pointer to attribte of root bridge, it is
- output parameter
-
- @retval EFI_INVALID_PARAMETER Attribute pointer is NULL
-
- @retval EFI_INVALID_PARAMETER RootBridgehandle is invalid.
-
- @retval EFI_SUCCESS Success to get attribute of interested root
- bridge.

-/**
- 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] This 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.
-

- ------------------------------------ ---------------------------------------
- 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.
