codeql.yml

# This workflow runs CodeQL against the repository.
#
# Results are uploaded to GitHub Code Scanning.
#
# Note: Important: This file only works with "CI" builds. "Platform" builds are
#                  supported with the codeql-platform.yml file.
#
# Note: This workflow only supports Windows as CodeQL CLI has confirmed issues running
#       against edk2-style codebases on Linux (only tested on Ubuntu). Therefore, this
#       workflow is written only for Windows but could easily be adapted to run on Linux
#       in the future if needed (e.g. swap out "windows" with agent OS var value, etc.).
#
#       For details about the Linux issue see: https://github.com/github/codeql-action/issues/1338
