Package: ibverbs-utils
Version: 1.2.1-2
Severity: normal

Certain kernel modules need to be loaded to use this stack, for example:

dannf@xps13:~$ sudo ibv_devinfo
Failed to get IB devices list: Function not implemented
dannf@xps13:~$ sudo modprobe ib_uverbs
dannf@xps13:~$ sudo ibv_devinfo
libibverbs: Warning: couldn't open config directory '/etc/libibverbs.d'.
No IB devices found

It seems like we could be loading the necessary modules automatically. Indeed, there seems to be code in the rdma-core repo for doing so:

redhat/rdma.udev-rules
redhat/rdma.kernel-init

Could we enable such a facility for Debian?

We have rdma-core in Debian unstable now. This source package provides a binary package called 'rdma-core' which provides the basic boot time support for systems that use the Linux kernel's remote direct memory access (RDMA) subystem which includes InfiniBand, iWARP, and RDMA over Converged Ethernet (RoCE).
