CI Templates

This folder contains azure pipeline yml templates for "Core" and "Platform" Continuous Integration and PR validation.

Common CI templates


This template compiles the Edk2 basetools from source. The steps in this template are conditional and will only run if variable pkg_count is greater than 0.

It also has two conditional steps only used when the toolchain contains GCC. These two steps use apt to update the system packages and add those necessary for Edk2 builds.

Core CI templates


This templates contains the jobs and most importantly the matrix of which packages and targets to run for Core CI.


This template is the main Core CI template. It controls all the steps run and is responsible for most functionality of the Core CI process. This template sets the pkg_count variable using the stuart_pr_eval tool when the build type is "pull request"


This template installs the node based tools used by the spell checker plugin. The steps in this template are conditional and will only run if variable pkg_count is greater than 0.

Platform CI templates


This template makes heavy use of pytools to build and run a platform in the Edk2 repo

Also uses basetools-build-steps.yml to compile basetools

Special Notes

  • For a build type of pull request it will conditionally build if the patches change files that impact the platform.
  • uses stuart_pr_eval to determine impact
  • For manual builds or CI builds it will always build the platform
  • It compiles basetools from source
  • Will use stuart_build --FlashOnly to attempt to run the built image if the Run parameter is set.
  • See the parameters block for expected configuration options
  • Parameter extra_install_step allows the caller to insert extra steps. This is useful if additional dependencies, tools, or other things need to be installed. Here is an example of installing qemu on Windows.

    - template: ../../.azurepipelines/templates/build-run-steps.yml
        - powershell: choco install qemu; Write-Host "##vso[task.prependpath]c:\Program Files\qemu"
          displayName: Install QEMU and Set QEMU on path # friendly name displayed in the UI
          condition: and(gt(variables.pkg_count, 0), succeeded())
