Building AMD SMI

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

(build_reqs)=

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 AMD SMI repository to your local Linux machine.

   git clone https://github.com/ROCm/amdsmi.git
   

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_py_wrapper)=

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.

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

(build_tests)=

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_tests)=

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_docs)=

Build the docs

To build the documentation, follow the instructions at Building documentation.
