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 ]
