doc: update build-from-source instructions
Users no longer need to explicitly generate configuration source code as they are now generated at build time. This patch updates the relevant instructions in the documentation. v3: * RELEASE now defaults to n. * Cleanup the unnecessary target `all` in the `make` commands * Remove menuconfig related stuff. * Refine the introductory paragraph as only steps on Ubuntu is introduced * Also introduce the targets introduced by PR #5791 v2: * Add python3 lxml as a dependency * Explain how to use out-of-tree XML files Tracked-On: #5644 Signed-off-by: Junjie Mao <junjie.mao@intel.com> Co-authored-by: Geoffroy Van Cutsem <geoffroy.vancutsem@intel.com>

Build the Hypervisor Configuration

**********************************

|
||||
Modify the Hypervisor Configuration
|
||||
===================================
|
||||
***********************************
|
||||
|
||||
The ACRN hypervisor leverages Kconfig to manage configurations; it is
|
||||
powered by ``Kconfiglib``. A default configuration is generated based on the
|
||||
board you have selected via the ``BOARD=`` command line parameter. You can
|
||||
make further changes to that default configuration to adjust to your specific
|
||||
requirements.
|
||||
The ACRN hypervisor is built with scenario encoded in an XML file (referred to
|
||||
as the scenario XML hereinafter). The scenario XML of a build can be found at
|
||||
``<build>/hypervisor/.scenario.xml``, where ``<build>`` is the name of the build
|
||||
directory. You can make further changes to this file to adjust to your specific
|
||||
requirements. Another ``make`` will rebuild the hypervisor using the updated
|
||||
scenario XML.
|
||||
|
||||
To generate hypervisor configurations, you must build the hypervisor
|
||||
individually. The following steps generate a default but complete
|
||||
configuration, based on the platform selected, assuming that you are at the
|
||||
top level of the acrn-hypervisor directory. The configuration file, named
|
||||
``.config``, can be found under the target folder of your build.
|
||||
The following commands show how to customize manually the scenario XML based on
|
||||
the predefined ``INDUSTRY`` scenario for ``nuc7i7dnb`` and rebuild the
|
||||
hypervisor.
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
$ cd hypervisor
|
||||
$ make defconfig BOARD=nuc7i7dnb SCENARIO=industry
|
||||
|
||||
The BOARD specified is used to select a ``defconfig`` under
|
||||
``misc/vm_configs/scenarios/``. The other command line-based options (e.g.
|
||||
``RELEASE``) take no effect when generating a defconfig.
|
||||
|
||||
To modify the hypervisor configurations, you can either edit ``.config``
|
||||
manually, or you can invoke a TUI-based menuconfig (powered by kconfiglib) by
|
||||
executing ``make menuconfig``. As an example, the following commands
|
||||
(assuming that you are at the top level of the acrn-hypervisor directory)
|
||||
generate a default configuration file, allowing you to modify some
|
||||
configurations and build the hypervisor using the updated ``.config``:
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
# Modify the configurations per your needs
|
||||
$ cd ../ # Enter top-level folder of acrn-hypervisor source
|
||||
$ make menuconfig -C hypervisor
|
||||
# modify your own "ACRN Scenario" and "Target board" that want to build
|
||||
# in pop up menu
|
||||
|
||||
Note that ``menuconfig`` is python3 only.
|
||||
|
||||
Refer to the help on menuconfig for a detailed guide on the interface:

||||

||||

|
||||

The build results are found in the ``build`` directory. You can specify
|
||||
a different Output folder by setting the ``O`` ``make`` parameter,
|
||||
for example: ``make O=build-nuc``.

The build results are found in the ``build`` directory. You can specify

a different build folder by setting the ``O`` ``make`` parameter,

(Modify the XML file per your needs)
|
||||
$ make
|
||||
|
||||
.. note::
|
||||
The ``BOARD`` and ``SCENARIO`` parameters are not needed because the
|
||||
information is retrieved from the corresponding ``BOARD_FILE`` and
|
||||
``SCENARIO_FILE`` XML configuration files. The ``TARGET_DIR`` parameter
|
||||
specifies what directory is used to store configuration files imported
|
||||
from XML files. If the ``TARGET_DIR`` is not specified, the original
|
||||
configuration files of acrn-hypervisor would be overridden.
|
||||
A hypervisor build memorizes the board and scenario previously
|
||||
configured. Thus, there is no need to duplicate BOARD and SCENARIO in the
|
||||
second ``make`` above.
|
||||
|
||||
Follow the same instructions to boot and test the images you created from your build.
|
||||
While the scenario XML files can be changed manually, we recommend to use the
|
||||
ACRN web-based configuration app which provides valid options and descriptions
|
||||
of the configuration entries. Refer to :ref:`acrn_config_tool_ui` for more
|
||||
instructions.

||||
Descriptions of each configuration entry in scenario XML files are also

Hypervisor Configuration Workflow

==================================
|

The hypervisor configuration is based on the ``Kconfig``
|

mechanism. Begin by creating a board-specific ``defconfig`` file to
|
||||
set up the default ``Kconfig`` values for the specified board.
|
||||
Next, configure the hypervisor build options using the ``make menuconfig``
|
||||
graphical interface or ``make defconfig`` to generate
|
||||
a ``.config`` file. The resulting ``.config`` file is
|
||||
used by the ACRN build process to create a configured scenario- and
|
||||
board-specific hypervisor image.
