Subject: ibv_reg_mr fails to register memory
Date: Tue, 11 Nov 2014 15:42:23 +0530	[thread overview]
Message-ID: <1415700743.7672.1.camel@rafi> (raw)

Hi All,

I was trying to implement an application that support rdma using
librdmacm. When the process is trying to register the buffer using
ibv_reg_mr, it failes after registering  some number buffer.

We are using Mellanox Technologies MT27500 Family [ConnectX-3] cards. 

Reconfigured options are :

1) cat /sys/module/mlx4_core/parameters/log_num_mtt
    24
2) cat /sys/module/mlx4_core/parameters/log_mtts_per_seg
    7

Can anyone point out reason behind ibv_reg_mr fails ?

Thanks & Regards
Rafi KC
