Building rocminfo
|
|
*****************
|
|
|
|
Use the standard CMake build procedure to build rocminfo. The ROCm root directory (the parent directory containing ROCM headers and libraries) must be provided as a CMake argument using the standard ``CMAKE_PREFIX_PATH`` variable.
|
|
|
|
After cloning the `rocminfo Git repository <https://github.com/ROCm/rocm-systems/tree/develop/projects/rocminfo>`_, run ``git-fetch --tags`` to retrieve the repository tags, which are used for versioning.
|
|
|
|
For example:
|
|
|
|
.. code-block::
|
|
|
|
$ git fetch --tags origin
|
|
|
|
Building from the CMakeLists.txt directory might look like this:
|
|
|
|
mkdir -p build
|
|
|
|
cd build
|
|
|
|
cmake -DCMAKE_PREFIX_PATH=/opt/rocm ..
|
|
|
|
make
|
|
|
|
cd ..
|
|
|
|
Upon a successful build, the rocminfo binary and the Python script ``rocm_agent_enumerator`` will present in the ``build`` directory.
|
|
|
|
rocminfo execution
|
|
-------------------
|
|
|
|
rocminfo reports information about HSA system attributes and agents.
|
|
|
|
``rocm_agent_enumerator`` prints a list of AMD GCN ISA or architecture names. With the option ``-name``, it prints out the available architecture names obtained from rocminfo. Otherwise, it generates the ISA in one of the following ways:
|
|
|
|
* ``ROCM_TARGET_LST``: A user-defined environment variable that specifies the path to the ``target.lst`` file. This can be used in a sandboxed install environment where executing rocminfo is not possible.
|
|
|
|
* ``target.lst``: A user-supplied text file in the same folder as ``rocm_agent_enumerator``. This can be used in a container environment where the ROCm stack is not available.
|
|
|
|
* HSA topology: Gathers information from the HSA node topology under ``/sys/class/kfd/kfd/topology/nodes/``.
|
|
|
|
* ``lspci``: Enumerates the PCI bus and locates supported devices from a hard-coded lookup table.
|
|
|
|
* rocminfo: A tool shipped with this script to enumerate GPU agents available on a working ROCm stack.
