Building AMD SMI

Building AMD SMI#

This section describes the prerequisites and steps to build AMD SMI from source.

Required software#

To build the AMD SMI library, the following components are required. Note that the software versions specified were used during development; earlier versions are not guaranteed to work.

  • CMake (v3.15.0 or later) – python3 -m pip install cmake

  • g++ (v5.4.0 or later)

  • libdrm-dev (for Ubuntu and Debian)

  • libdrm-devel (for RPM-based distributions)

In order to build the AMD SMI Python package, the following components are required:

  • Python (3.6.8 or later)

  • virtualenv – python3 -m pip install virtualenv

Build steps#

  1. Clone the rocm-systems repository to your local Linux machine and sparse-checkout the AMD SMI project.

    git clone --filter=blob:none --sparse https://github.com/ROCm/rocm-systems.git
git -C rocm-systems sparse-checkout set projects/amdsmi
cd rocm-systems/projects/amdsmi

  2. The default installation location for the library and headers is /opt/rocm. Before installation, any old ROCm directories should be deleted:

    • /opt/rocm

    • /opt/rocm-<version_number>

  3. Build the library by following the typical CMake build sequence (run as root user or use sudo before make install command); for instance:

    mkdir -p build
cd build
cmake ..
make -j $(nproc)
make install

    The built library is located in the build/ directory. To build the rpm and deb packages use the following command:

    make package

Rebuild the Python wrapper#

The Python wrapper for the AMD SMI library is found in the auto-generated file py-interface/amdsmi_wrapper.py. It is essential to regenerate this wrapper whenever there are changes to the C++ API. It is not regenerated automatically.

To regenerate the wrapper, use the following command.

./update_wrapper.sh

After this command, the file in py-interface/amdsmi_wrapper.py will be updated on compile.

Note

You need Docker installed on your system to regenerate the Python wrapper.

Build the tests#

To verify the build and capabilities of AMD SMI on your system, as well as to see practical examples of its usage, you can build and run the available tests in the repository. Follow these steps to build the tests:

mkdir -p build
cd build
cmake -DBUILD_TESTS=ON ..
make -j $(nproc)

Run the tests#

Once the tests are built, you can run them by executing the amdsmitst program. The executable can be found at build/tests/amd_smi_test/.

Build the docs#

The C/C++ API reference is generated with Doxygen 1.9.8, which must be installed separately and available on your PATH.

  1. Create a Python virtual environment and install documentation dependencies.

    # From rocm-systems/projects/amdsmi
python3.12 -m venv docs/.venv
source docs/.venv/bin/activate
pip install -r docs/sphinx/requirements.txt

  2. Use the following command to build the documentation using Sphinx.

    python -m sphinx docs docs/_build -j auto -E -v

  3. Open docs/_build/index.html in your web browser to view the documentation. To serve the site locally instead, run:

    python -m http.server -d docs/_build
# Go to http://localhost:8000 in your browser
