Background

This Continuous integration and testing infrastructure leverages the TianoCore EDKII Tools PIP modules: library and extensions (with repos located here and here).

The primary execution flows can be found in the .azurepipelines/Windows-VS2019.yml and .azurepipelines/Ubuntu-GCC5.yml files. These YAML files are consumed by the Azure Dev Ops Build Pipeline and dictate what server resources should be used, how they should be configured, and what processes should be run on them. An overview of this schema can be found here.

Inspection of these files reveals the EDKII Tools commands that make up the primary processes for the CI build: 'stuart_setup', 'stuart_update', and 'stuart_ci_build'. These commands come from the EDKII Tools PIP modules and are configured as described below. More documentation on the tools can be found here and here.

Configuration

Configuration of the CI process consists of (in order of precedence):

  • command-line arguments passed in via the Pipeline YAML
  • a per-package configuration file (e.g. <package-name>.ci.yaml) that is detected by the CI system in EDKII Tools.
  • a global configuration Python module (e.g. CISetting.py) passed in via the command-line

The global configuration file is described in this readme from the EDKII Tools documentation. This configuration is written as a Python module so that decisions can be made dynamically based on command line parameters and codebase state.

The per-package configuration file can override most settings in the global configuration file, but is not dynamic. This file can be used to skip or customize tests that may be incompatible with a specific package. Each test generally requires per package configuration which comes from this file.

Running CI locally

The EDKII Tools environment (and by extension the ci) is designed to support easily and consistently running locally and in a cloud ci environment. To do that a few steps should be followed. Details of EDKII Tools can be found in the docs folder here

Prerequisets

  1. A supported toolchain (others might work but this is what is tested and validated)
    • Windows 10:
      • VS 2017 or VS 2019
      • Windows SDK (for rc)
      • Windows WDK (for capsules)
    • Ubuntu 16.04
      • GCC5
    • Easy to add more but this is the current state
  2. Python 3.7.x or newer on path
  3. git on path
  4. Recommended to setup and activate a python virtual environment
  5. Install the requirements pip install --upgrade pip-requirements.txt

Running CI

  1. clone your edk2 repo
  2. Activate your python virtual environment in cmd window
  3. Get code dependencies (done only when submodules change)
    • stuart_setup -c .pytool/CISettings.py TOOL_CHAIN_TAG=<your tag here>
  4. Update other dependencies (done more often)
    • stuart_update -c .pytool/CISettings.py TOOL_CHAIN_TAG=<your tag here>
  5. Run CI build (--help will give you options)
    • stuart_ci_build -c .pytool/CISettings.py TOOL_CHAIN_TAG=<your tag here>
    • -p <pkg1,pkg2,pkg3> : To build only certain packages use a CSV list
    • -a <arch1,arch2,arch3>: To run only certain architectures use a CSV list
    • -t <target1,target2>: To run only tests related to certain targets use a CSV list
    • By default all tests are opted in. Then given a package.ci.yaml file those tests can be configured for a package. Finally setting the check to the value skip will skip that plugin. Examples:
      • CompilerPlugin=skip skip the build test
      • GuidCheck=skip skip the Guid check
      • SpellCheck=skip skip the spell checker
      • etc
  6. Detailed reports and logs per package are captured in the Build directory

Current PyTool Test Capabilities

All CI tests are instances of EDKII Tools plugins. Documentation on the plugin system can be found here and here. Upon invocation, each plugin will be passed the path to the current package under test and a dictionary containing its targeted configuration, as assembled from the command line, per-package configuration, and global configuration.

Note: CI plugins are considered unique from build plugins and helper plugins, even though some CI plugins may execute steps of a build.

In the example, these plugins live alongside the code under test (in the .pytool/Plugin directory), but may be moved to the 'edk2-test' repo if that location makes more sense for the community.

Module Inclusion Test - DscCompleteCheck

This test scans all available modules (via INF files) and compares them to the package-level DSC file for the package each module is contained within. The test considers it an error if any module does not appear in the Components section of at least one package-level DSC (indicating that it would not be built if the package were built).

Code Compilation Test - CompilerPlugin

Once the Module Inclusion Test has verified that all modules would be built if all package-level DSCs were built, the Code Compilation Test simply runs through and builds every package-level DSC on every toolchain and for every architecture that is supported. Any module that fails to build is considered an error.

GUID Uniqueness Test - GuidCheck

This test works on the collection of all packages rather than an individual package. It looks at all FILE_GUIDs and GUIDs declared in DEC files and ensures that they are unique for the codebase. This prevents, for example, accidental duplication of GUIDs when using an existing INF as a template for a new module.

Cross-Package Dependency Test - DependencyCheck

This test compares the list of all packages used in INFs files for a given package against a list of "allowed dependencies" in plugin configuration for that package. Any module that depends on a disallowed package will cause a test failure.

Library Declaration Test - LibraryClassCheck

This test scans at all library header files found in the Library folders in all of the package's declared include directories and ensures that all files have a matching LibraryClass declaration in the DEC file for the package. Any missing declarations will cause a failure.

Invalid Character Test - CharEncodingCheck

This test scans all files in a package to make sure that there are no invalid Unicode characters that may cause build errors in some character sets/localizations.

Spell Checking - cspell

This test runs a spell checker on all files within the package. This is done using the NodeJs cspell tool. For details check .pytool/Plugin/SpellCheck. For this plugin to run during ci you must install nodejs and cspell and have both available to the command line when running your CI.

Install

PyTool Scopes

Scopes are how the PyTool ext_dep, path_env, and plugins are activated. Meaning that if an invocable process has a scope active then those ext_dep and path_env will be active. To allow easy integration of PyTools capabilities there are a few standard scopes.

Scope Invocable Description
global edk2_invocable++ - should be base_abstract_invocable Running an invocables
global-win edk2_invocable++ Running on Microsoft Windows
global-nix edk2_invocable++ Running on Linux based OS
edk2-build This indicates that an invocable is building EDK2 based UEFI code
cibuild set in .pytool/CISettings.py Suggested target for edk2 continuous integration builds. Tools used for CiBuilds can use this scope. Example: asl compiler

Future investments

  • PatchCheck tests as plugins
  • MacOS/xcode support
  • Clang/LLVM support
  • Visual Studio AARCH64 and ARM support
  • BaseTools C tools CI/PR and binary release process
  • BaseTools Python tools CI/PR process
  • Extensible private/closed source platform reporting
  • UEFI SCTs
  • Other automation
