Subject: [dpdk-users] Mellanox Unexpected CQE error syndrome
Date: Thu, 29 Oct 2020 08:18:25 +0000	[thread overview]
Message-ID: <OSBPR01MB415228271CF923FE039945B4E4140@OSBPR01MB4152.jpnprd01.prod.outlook.com> (raw)

Hello,
I am having problem with HPE Ethernet 100Gb 2-port 841QSFP28 Adapter which is a Mellanox adapter for 100G network.

The DPDK driver reports and generates lot of error files like dpdk_mlx5_port_0_rxq_0_2459159054 and loses traffic (because IMHO it must reset the card):

the first line of the error report files is as follows:

Unexpected CQE error syndrome 0x22 CQN = 1030 RQN = 12582977 wqe_counter = 10040 rq_ci = 494774062 cq_ci = 3586794130

Unexpected CQE error syndrome 0x22 CQN = 1030 RQN = 12582977 wqe_counter = 46035 rq_ci = 3556062128 cq_ci = 2413356673
Unexpected CQE error syndrome 0x73 CQN = 1030 RQN = 12582977 wqe_counter = 0 rq_ci = 32768 cq_ci = 2532978172
Unexpected CQE error syndrome 0x40 CQN = 1030 RQN = 12582977 wqe_counter = 0 rq_ci = 32768 cq_ci = 3092052808

I have tried latest card HP firmware and enable/disable CQE compression in the mlx5 DPDK driver using rxq_cqe_comp_en=0/1, but no improvement.

Does anybody know what can be the problem and how to mitigate it?

Thanks
Pavel Krauz
