32 CoreInitializeDebugImageInfoTable (
39 Creates and initializes the DebugImageInfo Table. Also creates the configuration
40 table and registers it into the system table.
49 This function allocates memory, frees it, and then allocates memory at an
50 address within the initial allocation. Since this function is called early
51 in DXE core initialization (before drivers are dispatched), this should not
58 CoreUpdateDebugTableCrc32 (
65 Update the CRC32 in the Debug Table.
66 Since the CRC32 service is made available by the Runtime driver, we have to
67 wait for the Runtime Driver to be installed before the CRC32 can be computed.
68 This function is called elsewhere by the core when the runtime architectural

,
84 EFI_HANDLE ImageHandle
90 Adds a new DebugImageInfo structure to the DebugImageInfo Table. Re-Allocates
91 the table if it's not large enough to accomidate another entry.
95 ImageInfoType - type of debug image information
96 LoadedImage - pointer to the loaded image protocol for the image being loaded
97 ImageHandle - image handle for the image being loaded
106 CoreRemoveDebugImageInfoEntry (
107 EFI_HANDLE ImageHandle
113 Removes and frees an entry from the DebugImageInfo Table.
117 ImageHandle - image handle for the image being unloaded
