Function Documentation

FspWrapperNotifyDxeEntryPoint()

EFI_STATUS EFIAPI FspWrapperNotifyDxeEntryPoint	(	IN EFI_HANDLE	ImageHandle,
		IN EFI_SYSTEM_TABLE *	SystemTable
	)

Main entry for the FSP DXE module.

This routine registers two callbacks to call fsp's notifies.

Parameters

[in]	ImageHandle	The firmware allocated handle for the EFI image.
[in]	SystemTable	A pointer to the EFI System Table.

Return values

EFI_SUCCESS	The entry point is executed successfully.
other	Some error occurs when executing this entry point.

OnEndOfFirmware()

VOID EFIAPI OnEndOfFirmware	(	IN EFI_EVENT	Event,
		IN VOID *	Context
	)

This stage is notified just before the firmware/Preboot environment transfers management of all system resources to the OS or next level execution environment.

Parameters

Event	Event whose notification function is being invoked.
Context	Pointer to the notification function's context, which is always zero in current implementation.

Definition at line 164 of file FspWrapperNotifyDxe.c.

OnPciEnumerationComplete()

VOID EFIAPI OnPciEnumerationComplete	(	IN EFI_EVENT	Event,
		IN VOID *	Context
	)

PciEnumerationComplete Protocol notification event handler.

Parameters

[in]	Event	Event whose notification function is being invoked.
[in]	Context	Pointer to the notification function's context.

Definition at line 68 of file FspWrapperNotifyDxe.c.

OnReadyToBoot()

VOID EFIAPI OnReadyToBoot	(	IN EFI_EVENT	Event,
		IN VOID *	Context
	)

Notification function of EVT_GROUP_READY_TO_BOOT event group.

This is a notification function registered on EVT_GROUP_READY_TO_BOOT event group. When the Boot Manager is about to load and execute a boot option, it reclaims variable storage if free size is below the threshold.

Parameters

[in]	Event	Event whose notification function is being invoked.
[in]	Context	Pointer to the notification function's context.

EFI_STATUS RelocateImageUnder4GIfNeeded	(	IN EFI_HANDLE	ImageHandle,
		IN EFI_SYSTEM_TABLE *	SystemTable
	)

Relocate this image under 4G memory.

Parameters

ImageHandle	Handle of driver image.
SystemTable	Pointer to system table.

Return values

EFI_SUCCESS	Image successfully relocated.
EFI_ABORTED	Failed to relocate image.
