Please unblock package hwloc-contrib [ Reason ] hwloc-contrib currently FTBFS due to #984984 : nvidia-alternative fixed providing libnvidia-ml.so, and thus hwloc-contrib is now able to build its nvml plugin but dh_missing complains that it was not configured to. In the hwloc-contrib/2.4.1+dfsg-2 upload, I re-enabled installing the nvml plugin, as the attached patch shows. [ Impact ] Without the nvml plugin, it is harder for hwloc-based applications to determine the locality of GPUs in the system, and thus to optimize data transfers and get efficient execution. [ Tests ] I have tested it on a system that has GPUs, the nvml location is correct. [ Risks ] The code change is trivial :) The consequence for systems without a GPU is just an nvmlInit() call that will report that there is no nvml device. For systems with a GPU, the nvml plugin just gets information from libnvidia-ml and stores it for applications that would want it. Alternatively, we could mark the nvml plugin as not-installed. [ Checklist ] [X] all changes are documented in the d/changelog [X] I reviewed all changes and I approve them [X] attach debdiff against the package in testing unblock hwloc-contrib/2.4.1+dfsg-2
