\pard\keep\keepn\nowidctlpar\s2\li-1440\sb400\sa60\sl-340\slmult0\cf1\fs28 Description\par
|
||
\pard\nowidctlpar\sb200\cf2\b0\fs18 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. \f1\par
|
||
\f0 GenPatchPcdTable tool usually works together with PatchPcdValue tool to set the specific value of a patchable PCD into the binary EFI image. \f1\par
