Function Documentation

CoreInitializeDebugImageInfoTable()

VOID CoreInitializeDebugImageInfoTable

(

VOID

)

Creates and initializes the DebugImageInfo Table. Also creates the configuration table and registers it into the system table.

Definition at line 30 of file DebugImageInfo.c.

CoreNewDebugImageInfoEntry()

VOID CoreNewDebugImageInfoEntry	(	IN UINT32	ImageInfoType,
		IN EFI_LOADED_IMAGE_PROTOCOL *	LoadedImage,
		IN EFI_HANDLE	ImageHandle
	)

Adds a new DebugImageInfo structure to the DebugImageInfo Table. Re-Allocates the table if it's not large enough to accomidate another entry.

Parameters

ImageInfoType	type of debug image information
LoadedImage	pointer to the loaded image protocol for the image being loaded
ImageHandle	image handle for the image being loaded

Definition at line 162 of file DebugImageInfo.c.

CoreRemoveDebugImageInfoEntry()

VOID CoreRemoveDebugImageInfoEntry

(

EFI_HANDLE

ImageHandle

)

Removes and frees an entry from the DebugImageInfo Table.

Parameters

ImageHandle

image handle for the image being unloaded

Definition at line 253 of file DebugImageInfo.c.

CoreUpdateDebugTableCrc32()

VOID CoreUpdateDebugTableCrc32

(

VOID

)

Update the CRC32 in the Debug Table. Since the CRC32 service is made available by the Runtime driver, we have to wait for the Runtime Driver to be installed before the CRC32 can be computed. This function is called elsewhere by the core when the runtime architectural protocol is produced.
