Function Documentation

CoreAllEfiServicesAvailable()

EFI_STATUS CoreAllEfiServicesAvailable

(

VOID

)

Return TRUE if all AP services are available.

Return values

EFI_SUCCESS	All AP services are available
EFI_NOT_FOUND	At least one AP service is not available

Definition at line 80 of file DxeProtocolNotify.c.

CoreDisplayMissingArchProtocols()

VOID CoreDisplayMissingArchProtocols

(

VOID

)

Displays Architectural protocols that were not loaded and are required for DXE core to function. Only used in Debug Builds.

Definition at line 262 of file DxeProtocolNotify.c.

CoreNotifyOnProtocolEntryTable()

VOID CoreNotifyOnProtocolEntryTable

(

EFI_CORE_PROTOCOL_NOTIFY_ENTRY *

Entry

)

Creates an event for each entry in a table that is fired everytime a Protocol of a specific type is installed.

Parameters

Entry

Pointer to EFI_CORE_PROTOCOL_NOTIFY_ENTRY.

Definition at line 211 of file DxeProtocolNotify.c.

CoreNotifyOnProtocolInstallation()

VOID CoreNotifyOnProtocolInstallation

(

VOID

)

Creates an events for the Architectural Protocols and the optional protocols that are fired everytime a Protocol of a specific type is installed.

Definition at line 248 of file DxeProtocolNotify.c.

GenericProtocolNotify()

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

Notification event handler registered by CoreNotifyOnArchProtocolInstallation (). This notify function is registered for every architectural protocol. This handler updates mArchProtocol[] array entry with protocol instance data and sets it's present flag to TRUE. If any constructor is required it is executed. The EFI System Table headers are updated.

Parameters

Event	The Event that is being processed, not used.
Context	Event Context, not used.
