Kindest regards, Raslan Darawsheh From: Panagiotis Famelis <pfame...@ubitech.eu> Sent: Wednesday, August 17, 2022 10:54 AM To: dev@dpdk.org Subject: mlx5_common failed errno=121 Hello, I am trying to run p4-dpdk-target (https://github.com/p4lang/p4-dpdk-target), with DPDK version 22.07.0-rc2 (the one provided by the p4-dpdk-target). However, when I run the bf_switchd I get the following error, by the dpdk driver: """ mlx5_common: DevX read access NIC register=0X9055 failed errno=121 status=0x3 syndrome=0x54e3a9 mlx5_common: DevX create q counter set failed errno=121 status=0x2 syndrome=0x8975f1 """ The same error appears when running dpdk-testpmd (by the above DPDK version). The NIC is an NVIDIA/ Mellanox Connect-X 5. I have also tested with DPDK version 21.11.0 and it doesn't show this error and works correctly. Do you have any suggestions on what that particular error might be and how to fix it? It seems like it tries to read a wrong register, but I am not sure. Thank you for your help. Best Regards, Panagiotis Famelis.
