◆ NotifyPhase()

EFI_STATUS NotifyPhase	(	IN EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL *	PciResAlloc,
		EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PHASE	Phase
	)

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.

Parameters

[in]	PciResAlloc	The instance pointer of EFI_PCI_HOST_BRIDGE_RESOURCE_ALLOCATION_PROTOCOL
[in]	Phase	The phase during enumeration

Return values

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
EFI_DEVICE_ERROR	Programming failed due to a hardware error. This error is valid for a Phase of EfiPciHostBridgeSetResources.
EFI_INVALID_PARAMETER	Invalid phase parameter
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.
EFI_SUCCESS	The notification was accepted without any errors.
