Name

GenPatchPcdTable.exe or GenPatchPcdTable.py - Parse the binary EFI image and its map file to get all used patchable PCDs' name and their offset in EFI image.

Synopsis

  GenPatchPcdTable.exe -m <MapFile> -e <EfiFile> [-o <OutFile>]
​
  GenPatchPcd.exe -h
​
  GenPatchPcd.exe --version

Description

GenPatchPcdTable tool parses the binary EFI image and map file generated by the different compilers (including MSFT, ICC, GCC) in EDKII code base. This tool searches the image map file to find every patchable PCD name and its real address, then parse the binary EFI image to get each section name and address, and calculate PCD offset in the binary EFI image. Finally, Pcd name, its offset and section name will be written into the output file.

GenPatchPcdTable tool usually works together with PatchPcdValue tool to set the specific value of a patchable PCD into the binary EFI image.

Options

If no options are specified, tool prints usage.

  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -m MAPFILE, --mapfile=MAPFILE
                        Absolute path of module map file.
  -e EFIFILE, --efifile=EFIFILE
                        Absolute path of EFI binary file.
  -o OUTFILE, --outputfile=OUTFILE
                        Absolute path of output file to store the got
                        patchable PCD table.

Status codes returned

Always return 0.

Example

1. Get the patchable Pcds from the binary PeiCore image and PeiCore map file,

   and output the PCD information into the file PcdTable.txt.

  GenPatchPcdTable.exe -m PeiCore.map -e PeiCore.efi -o PcdTable.txt

PcdTable.txt file contains the following PCD information:
