ArmVirtPkg - Platform CI

This Readme.md describes the Azure DevOps based Platform CI for ArmVirtPkg and how to use the same Pytools based build infrastructure locally.

Supported Configuration Details

This solution for building and running ArmVirtPkg has only been validated with Ubuntu 18.04 and the GCC5 toolchain. Two different firmware builds are supported and are described below.

Configuration name Architecture DSC File Additional Flags
AARCH64 AARCH64 ArmVirtQemu.dsc None
ARM ARM ArmVirtQemu.dsc None

EDK2 Developer environment

Note: edksetup, Submodule initialization and manual installation of NASM, iASL, or the required cross-compiler toolchains are not required, this is handled by the Pytools build system.

Building with Pytools for ArmVirtPkg

  1. [Optional] Create a Python Virtual Environment - generally once per workspace

    python -m venv <name of virtual environment>

  2. [Optional] Activate Virtual Environment - each time new shell opened

    • Windows

      <name of virtual environment>/Scripts/activate.bat

    • Linux

      source <name of virtual environment>/bin/activate

  3. Install Pytools - generally once per virtual env or whenever pip-requirements.txt changes

    pip install --upgrade -r pip-requirements.txt

  4. Initialize & Update Submodules - only when submodules updated

    stuart_setup -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>

  5. Initialize & Update Dependencies - only as needed when ext_deps change

    stuart_update -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>

  6. Compile the basetools if necessary - only when basetools C source files change

    python BaseTools/Edk2ToolsBuild.py -t <ToolChainTag>

  7. Compile Firmware

    stuart_build -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH>
    • use stuart_build -c ArmVirtPkg/PlatformCI/PlatformBuild.py -h option to see additional options like --clean

  8. Running Emulator

    • You can add --FlashRom to the end of your build command and the emulator will run after the build is complete.

    • or use the --FlashOnly feature to just run the emulator.

      stuart_build -c ArmVirtPkg/PlatformCI/PlatformBuild.py TOOL_CHAIN_TAG=<TOOL_CHAIN_TAG> -a <TARGET_ARCH> --FlashOnly

Notes

  1. Including the expected build architecture and toolchain to the stuart_update command is critical. This is because there are extra scopes and tools that will be resolved during the update step that need to match your build step.
  2. Configuring ACTIVE_PLATFORM and TARGET_ARCH in Conf/target.txt is not required. This environment is set by PlatformBuild.py based upon the [-a <TARGET_ARCH>] parameter.
  3. QEMU must be on your path. On Windows this is a manual process and not part of the QEMU installer.

NOTE: Logging the execution output will be in the normal stuart log as well as to your console.

Custom Build Options

MAKE_STARTUP_NSH=TRUE will output a startup.nsh file to the location mapped as fs0. This is used in CI in combination with the --FlashOnly feature to run QEMU to the UEFI shell and then execute the contents of startup.nsh.

QEMU_HEADLESS=TRUE Since CI servers run headless QEMU must be told to run with no display otherwise an error occurs. Locally you don't need to set this.

Passing Build Defines

To pass build defines through stuart_build, prepend BLD_*_to the define name and pass it on the command-line. stuart_build currently requires values to be assigned, so add an=1 suffix for bare defines. For example, to enable the TPM2 support, instead of the traditional "-D TPM2_ENABLE=TRUE", the stuart_build command-line would be:

stuart_build -c ArmVirtPkg/PlatformCI/PlatformBuild.py BLD_*_TPM2_ENABLE=TRUE
