Hello, On systems with NVidia GPU devices, opencl devices don't show up in lstopo. Running in debug mode shows that they are detected:
1 OpenCL platforms This is opencl0d0 but then topology-opencl.c stops there and does not create an osdev object. AMD GPUs with non-PCIe device type are not reported either. I know that in these cases, we don't know where the GPUs are connected exactly, but we already have code coping with this: if (!parent) parent = hwloc_get_root_obj(topology); Isn't it better to show OpenCL at the root rather then not at all? It would be a matter of dropping the "continue;" lines.
