allow infiniband for non root users
- by user1219721
I got Infiniband running on RHEL 6.3
[root@master ~]# ibv_devinfo 
hca_id: mthca0
transport:          InfiniBand (0)
fw_ver:             4.7.927
node_guid:          0017:08ff:ffd0:6f1c
sys_image_guid:         0017:08ff:ffd0:6f1f
vendor_id:          0x08f1
vendor_part_id:         25208
hw_ver:             0xA0
board_id:           VLT0060010001
phys_port_cnt:          2
    port:   1
        state:          PORT_ACTIVE (4)
        max_mtu:        2048 (4)
        active_mtu:     2048 (4)
        sm_lid:         2
        port_lid:       3
        port_lmc:       0x00
        link_layer:     InfiniBand
    port:   2
        state:          PORT_DOWN (1)
        max_mtu:        2048 (4)
        active_mtu:     512 (2)
        sm_lid:         0
        port_lid:       0
        port_lmc:       0x00
        link_layer:     InfiniBand
but it's only working as root.
when trying from a non-super user, I got nothing :
[nicolas@master ~]$ ibv_devices
device                 node GUID
------              ----------------
mthca0              001708ffffd06f1c
So, how to allow regular users to use infiniband ?
