    permanent setting log_num_mtt and log_mtts_per_seg

    douraku

      I am using MHEH29 with MLNX_OFED 1.5.3. on centos 6.2.

      To increase memory size, I set log_num_mtt and log_mtts_per_seg as

      #echo "22" > /sys/module/mlx4_core/parameters/log_num_mtt

      #echo "1" > /sys/module/mlx4_core/parameters/log_mtts_per_seg

       

      Once these values are set, IPoIB works fine, but these values return to 0 upon rebooting.

      According to the discussion in this forum, HowTo Increase Memory Size used by Mellanox Adapters

      I looked for the file /etc/modprobe.d/mlx4_core.conf, but cannot find that file.

      Is there any way to set those values permanently?

      Where should I look for the mlx4_core.conf file other than the above directory?
