MFD libibverbs utils

Module for libibverbs - tools to get information about RDMA devices on system.

Usage

IBVDevices

from mfd_libibverbs_utils import IBVDevices
from mfd_connect import RPyCConnection

conn = RPyCConnection(name='10.10.10.10')
ibv_dev = IBVDevices(connection=conn)
devices = ibv_dev.get_list()

example output:

[IBDevice(device='mlx5_0', node_guid='506b4b0300ccf69e'),
IBDevice(device='cxgb4_0', node_guid='0007434742000000')]

IBVDevinfo

from mfd_libibverbs_utils import IBVDevinfo
from mfd_connect import RPyCConnection

conn = RPyCConnection(name='10.10.10.10')
devinfo = IBVDevinfo(connection=conn)
devices = devinfo.get_info()

example output:

[IBDeviceInfo(name='cxgb4_0', transport='iWARP (1)', fw_ver='1.23.4.0', node_guid='0007:4347:4200:0000',
                         sys_image_guid='0007:4347:4200:0000', vendor_id='0x1425', vendor_part_id='25608',
                         hw_ver='0x0', board_id='1425.6408', phys_port_cnt=2, 
                         physical_ports=[
                                  IBDevPhysicalPort(number=1, state='PORT_DOWN (1)', max_mtu=4096, 
                                                    active_mtu=1024, sm_lid=0, port_lid=0, 
                                                    port_lmc='0x00', link_layer='Ethernet')])]
