Hi Bill, 

There shouldn’t be any problem with what you are doing.
We are checking this now.

Best Regards,
Olga

Subject: [dpdk-dev] Mellanox PMD failure w/DPDK-2.1.0 and MLNX_OFED-3.1-1.0.3

Hello

I wonder if anyone can suggest why previously working dpdk code may fail in the Mellanox pmd code in dpdk-2.1.0, seemingly due to failure to create a "resource domain" via ibv_exp_create_res_domain(). I must admit I haven't seen that verb before, and it appears to be returning null with no error message.

The DPDK log gives these hints:

PMD: librte_pmd_mlx4: 0xa4fc20: TX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0xa4fc20: RX queues number update: 0 -> 1
PMD: librte_pmd_mlx4: 0xa4fc20: RD creation failure: Cannot allocate memory

I'm using dpdk-2.10.0 and  MLNX_OFED_LINUX-3.1-1.0.3 on ubuntu14.04 with a
connectx-3 card.

thanks
bill
