This guide describes all features and uses of the tool.
About the Board Inspector Tool
******************************
The Board Inspector tool ``board_inspector.py`` enables you to generate a board
configuration file on the target system. The board configuration file stores
hardware-specific information extracted from the target platform and is used to
customize your :ref:`ACRN configuration <acrn_configuration_tool>`.
Generate a Board Configuration File
***********************************
.. important::
Whenever you change the configuration of the board, such as BIOS settings,
additional memory, or PCI devices, you must generate a new board
configuration file.
The following steps describe all options in the Board Inspector for generating
a board configuration file.
#. Make sure the target system is set up and ready to run the Board Inspector,
according to :ref:`gsg-board-setup` in the Getting Started Guide.
#. Run the Board Inspector tool (``board_inspector.py``) to generate the board
configuration file. This example assumes the tool is in the
``~/acrn-work/`` directory and ``my_board`` is the desired file
name. Feel free to modify the commands as needed.
.. code-block:: bash
cd ~/acrn-work/board_inspector/
sudo python3 board_inspector.py my_board
Upon success, the tool displays a message similar to this example:
.. code-block:: console
my_board.xml saved successfully!
#. Confirm that the board configuration file ``my_board.xml`` was generated in
the current directory.

Command-Line Options
********************
You can configure the Board Inspector via command-line options. Running the
Board Inspector with the ``-h`` option yields the following usage message:
.. code-block::
usage: board_inspector.py [-h] [--out OUT] [--basic] [--loglevel LOGLEVEL]
[--check-device-status] board_name
positional arguments:
board_name the name of the board that runs the ACRN hypervisor
optional arguments:
-h, --help show this help message and exit
--out OUT the name of board info file
--basic do not extract advanced information such as ACPI namespace
--loglevel LOGLEVEL choose log level, e.g. info, warning or error
--check-device-status
filter out devices whose _STA object evaluates to 0
Details about certain arguments:
.. list-table::
:widths: 33 77
:header-rows: 1
* - Argument
- Details
* - ``board_name``
- Required. The board name is used as the file name of the board
configuration file and is placed inside the file for other tools to read.
* - ``--out``
- Optional. Specify a file path where the board configuration file will be
saved (example: ``~/acrn_work``). If only a filename is provided in this
option, the Board Inspector will generate the file in the current
directory.
* - ``--basic``
- Optional. By default, the Board Inspector parses the ACPI namespace when
generating board configuration files. This option provides a way to
disable ACPI namespace parsing in case the parsing blocks the generation
of board configuration files.
* - ``--loglevel``
- Optional. Choose log level, e.g., info, warning or error.
(Default is warning.)
* - ``--check-device-status``
- Optional. On some boards, the device status (reported by the _STA
object) returns 0 while the device object is still useful for
pass-through devices. By default, the Board Inspector includes the
devices in the board configuration file. This option filters out the
devices, so that they cannot be used.
