What it is
----------
These patches add python BIOS build scripts and build configuration files to build platforms under Intel/Platform.
Why
----
The reason behind this implementation is to use a cross platform build script to build minplaform BIOS.
How it is done
----------------
The python files:
-----------------
build_bios.py: The main build file. This script sets up the edk2 build enviroment using the default build.cfg settings and platform specific settings. It uses the configurations found in the build.cfg file to locate the platforms that are configured to use this build script.
The path to each of the platform settings can be found under the "PLATFORMS"
field within the build.cfg file. The platform specific settings are located in the platform's main directory.
Example edk2-platforms/Platform/Intel/ClevoOpenBoardPkg/N1xxWU/build_config.cfg.
The build_bios.py script contains the four main functions:
- pre_build: Sets up the edk2 build enviroment variables, target.txt file
- build: Uses the configurations to Build BIOS
- post_build: Does post build processes like cleaning up files
generated during the build process
- clean: Cleans up the build directory.
There are four addtional functions that dynamically import functions from the board's Optional/Additional python script if specified in board settings file's ADDITIONAL_SCRIPTS These four functions are the pre_build_board, build_board, post_build_board, clean_ex functions
Board additional (Optional) python build script:
------------------------------------------------
These are python scripts located in the board's main directory, An example Intel/KabylakeOpenBoardPkg/KabylakeRvp3/build_board.py
If added, its path must be specified in board's settings file, under the field ADDITIONAL_SCRIPTS.
Example ADDITIONAL_SCRIPTS = PurleyOpenBoardPkg/BoardMtOlympus/build_board.py
If specified, the build_board, pre_build_board, post_build_board, clean_ex must be defined even if they are not use
The config files
-----------------
build.cfg:
-----------
This is file contains the default BIOS build configuration.
The default configurations are defined under the "DEFAULT_CONFIG" section of the file.
Each of these can be overridden by the board specific setting as defined in the board's build config file. All paths must be separated by forward slashes.
All the paths in the main build.cfg are relative to the minplaform WORKSPACE.
Example:
--------
[DEFAULT_CONFIG]
MIN_PACKAGE_TOOLS = edk2-platforms/Platform/Intel/MinPlatformPkg/Tools
The PLATFORMS field in the build.cfg file informs build_bios.py about the available platforms that can be built with the build_bios.py.
The path to the board specific config file must be relative to location of build_bios.py, Platform/Intel. It is in the format Boardname = BoardPath
Example:
--------
[PLATFORMS]
KabylakeRvp3 = KabylakeOpenBoardPkg/KabylakeRvp3/build_config.cfg
Board Specific Build Settings file:
----------------------------------------
This file is located in the board's main directory.
The CONFIG field contains all the build enviroment variables.
These values will override any the were specific under DEFAULT_CONFIG in the default build.cfg file.
Example is Intel/KabylakeOpenBoardPkg/KabylakeRvp3/build_config.cfg
Building BIOS
-------------
python build_bios.py -p BOARDNAME -t TOOLCHAIN
usage: build_bios.py [-h] --platform {N1xxWU,KabylakeRvp3,BoardMtOlympus}
[--toolchain TOOLCHAIN] [--DEBUG] [--RELEASE]
[--TEST_RELEASE] [--RELEASE_PDB] [--list] [--cleanall]
[--capsule] [--silent] [--performance] [--fsp] Build Help
optional arguments:
-h, --help show this help message and exit
--platform {N1xxWU,KabylakeRvp3,BoardMtOlympus}, -p {N1xxWU,KabylakeRvp3,BoardMtOlympus}
the platform to build
--toolchain TOOLCHAIN, -t TOOLCHAIN
using the Tool Chain Tagname to build the
platform, overriding target.txt's TOOL_CHAIN_TAG
definition
--DEBUG, -d debug flag
--RELEASE, -r release flag
--TEST_RELEASE, -tr test release flag
--RELEASE_PDB, -rp release flag
--list, -l lists available platforms
--cleanall cleans all
--clean cleans specific platform
--capsule capsule build enabled
--silent silent build enabled
--performance performance build enabled
--fsp fsp build enabled
