USER COMMANDS                                      IBV_DEVICES(1)



NAME
     ibv_devices - list InfiniBand devices


SYNOPSIS
     ibv_devices


DESCRIPTION
     List InfiniBand 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   following  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
