CoreInitializeDebugImageInfoTable ( | |
VOID | |
) | |
/*++ | |
Routine Description: | |
Creates and initializes the DebugImageInfo Table. Also creates the configuration | |
table and registers it into the system table. | |
Arguments: | |
None | |
Returns: | |
NA | |
Notes: | |
This function allocates memory, frees it, and then allocates memory at an | |
address within the initial allocation. Since this function is called early | |
in DXE core initialization (before drivers are dispatched), this should not | |
be a problem. | |

CoreUpdateDebugTableCrc32 ( | |
VOID | |
) | |
/*++ | |
Routine Description: | |
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. | |
Arguments: | |
None | |
Returns: | |
NA | |

CoreNewDebugImageInfoEntry ( | |

/*++ | |
Routine Description: | |
Adds a new DebugImageInfo structure to the DebugImageInfo Table. Re-Allocates | |
the table if it's not large enough to accomidate another entry. | |
Arguments: | |
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 | |
Returns: | |
NA | |

CoreRemoveDebugImageInfoEntry ( | |

/*++ | |
Routine Description: | |
Removes and frees an entry from the DebugImageInfo Table. | |
Arguments: | |
ImageHandle - image handle for the image being unloaded | |
Returns: | |
NA | |
