IBV_DEVICES(1)                   USER COMMANDS                  IBV_DEVICES(1)



NAME
       ibv_devices - list RDMA devices


SYNOPSIS
       ibv_devices


DESCRIPTION
       List RDMA devices available for use from userspace.

       On  SR-IOV capable systems, if a domain is configured with VFs (Virtual
       Function), ibv_devices lists for each IB device the node GUID  and  the
       type (PF or VF).  In this case, the PF devices are displayed before the
       VF devices.  The following shows the results of running ibv_devices  on
       a domain with one PF and two VFs:

           device                 node GUID            type
           ------              ----------------        ----
           mlx4_2              00212800013f3126         PF
           mlx4_0              00212d00013f3126         VF
           mlx4_1              00212900013f3126         VF

       If all of the IB devices are PFs, only node GUIDs are listed.  The fol-
       lowing shows the results of running ibv_devices on a domain with one PF
       and no VFs:

           device                 node GUID
           ------              ----------------
           mlx4_0              00212800013f3126

       On systems which are not SR-IOV capable only node GUIDs are listed.

           device                 node GUID
           ------              ----------------
           mlx4_0              0021280001a0e4d8
           mlx4_1              0021280001a0e754
