D.2 Vpd Info File Format

The Vpd Info file contains an ordered list of the VPD PCDs, replacing any wildcard character values that may appear in the DSC file, with the actual computed (by the external tool - named by GUID in the Conf/tools_def.txt file) values. The file is named by the GUID value of the tool named by GUID and uses a ".map" extension. It is generated in the platform's FV directory.

Summary

This file is used by the AutoGen functions in the EDK II build system to generate the PCD database used for Dynamic an DynamicEx PCDs. Blank lines and lines that start with the hash "#" character (used for comments) are skipped when processing this file. Each comment must appear on its own line or it can be appended after an entry. Line extensions are not permitted.
