I am trying to use the example programs and testpmd, but they fail with some errors (see outputs below). The testpmd program also does not go into interactive mode and exits after a keypress. I am using Windows Server 2022 with a Mellanox ConnectX-4 LX Card using Win-OF 2 2.90.50010 / SDK 2.90.25518. I am using the current build (DPDK Version 22.07-rc3).<o:p></o:p> I followed to DPDK Windows guide, but currently I always get the following error: mlx5_common: DevX read access NIC register=0X9055 failed errno=0 status=0 syndrome=0<o:p></o:p> does anybody have an idea how to resolve this problem, or at least get some more information why it failed?<o:p></o:p> Helloworld output:<o:p></o:p> C:\dpdk\build\examples>dpdk-helloworld.exe<o:p></o:p> EAL: Detected CPU lcores: 24<o:p></o:p> EAL: Detected NUMA nodes: 2<o:p></o:p> EAL: Multi-process support is requested, but not available.<o:p></o:p> EAL: Probe PCI driver: mlx5_pci (15b3:1015) device: 0000:06:00.0 (socket 0)<o:p></o:p> mlx5_common: DevX read access NIC register=0X9055 failed errno=0 status=0 syndrome=0<o:p></o:p> mlx5_net: mlx5_os_dev_shared_handler_install: is not supported<o:p></o:p> mlx5_net: Rx CQE 128B compression is not supported.<o:p></o:p> EAL: Probe PCI driver: mlx5_pci (15b3:1015) device: 0000:06:00.1 (socket 0)<o:p></o:p> mlx5_common: DevX read access NIC register=0X9055 failed errno=0 status=0 syndrome=0<o:p></o:p> mlx5_net: mlx5_os_dev_shared_handler_install: is not supported<o:p></o:p> mlx5_net: Rx CQE 128B compression is not supported.<o:p></o:p> hello from core 1<o:p></o:p> hello from core 2<o:p></o:p> hello from core 3<o:p></o:p> hello from core 4<o:p></o:p> hello from core 5<o:p></o:p> hello from core 6<o:p></o:p> hello from core 7<o:p></o:p> hello from core 8<o:p></o:p> hello from core 16<o:p></o:p> hello from core 22<o:p></o:p> hello from core 11<o:p></o:p> hello from core 12<o:p></o:p> hello from core 13<o:p></o:p> hello from core 14<o:p></o:p> hello from core 15<o:p></o:p> hello from core 9<o:p></o:p> hello from core 17<o:p></o:p> hello from core 18<o:p></o:p> hello from core 19<o:p></o:p> hello from core 20<o:p></o:p> hello from core 21<o:p></o:p> hello from core 23<o:p></o:p> hello from core 0<o:p></o:p> hello from core 10<o:p></o:p> <o:p> </o:p> testpmd output:<o:p></o:p> C:\dpdk\build\app>dpdk-testpmd.exe<o:p></o:p> EAL: Detected CPU lcores: 24<o:p></o:p> EAL: Detected NUMA nodes: 2<o:p></o:p> EAL: Multi-process support is requested, but not available.<o:p></o:p> EAL: Probe PCI driver: mlx5_pci (15b3:1015) device: 0000:06:00.0 (socket 0)<o:p></o:p> mlx5_common: DevX read access NIC register=0X9055 failed errno=0 status=0 syndrome=0<o:p></o:p> mlx5_net: mlx5_os_dev_shared_handler_install: is not supported<o:p></o:p> mlx5_net: Rx CQE 128B compression is not supported.<o:p></o:p> EAL: Probe PCI driver: mlx5_pci (15b3:1015) device: 0000:06:00.1 (socket 0)<o:p></o:p> mlx5_common: DevX read access NIC register=0X9055 failed errno=0 status=0 syndrome=0<o:p></o:p> mlx5_net: mlx5_os_dev_shared_handler_install: is not supported<o:p></o:p> mlx5_net: Rx CQE 128B compression is not supported.<o:p></o:p> testpmd: create a new mbuf pool <mb_pool_0>: n=331456, size=2176, socket=0<o:p></o:p> testpmd: preferred mempool ops selected: ring_mp_mc<o:p></o:p> testpmd: create a new mbuf pool <mb_pool_1>: n=331456, size=2176, socket=1<o:p></o:p> testpmd: preferred mempool ops selected: ring_mp_mc<o:p></o:p> Configuring Port 0 (socket 0)<o:p></o:p> mlx5_net: port 0 failed to set defaults flows<o:p></o:p> Fail to start port 0: Invalid argument<o:p></o:p> Configuring Port 1 (socket 0)<o:p></o:p> mlx5_net: port 1 failed to set defaults flows<o:p></o:p> Fail to start port 1: Invalid argument<o:p></o:p> Please stop the ports first<o:p></o:p> Done<o:p></o:p> No commandline core given, start packet forwarding<o:p></o:p> Not all ports were started<o:p></o:p> Press enter to exit<o:p></o:p> <o:p> </o:p> <o:p> </o:p> Stopping port 0...<o:p></o:p> Stopping ports...<o:p></o:p> Done<o:p></o:p> <o:p> </o:p> Stopping port 1...<o:p></o:p> Stopping ports...<o:p></o:p> Done<o:p></o:p> <o:p> </o:p> Shutting down port 0...<o:p></o:p> Closing ports...<o:p></o:p> mlx5_net: mlx5_os_dev_shared_handler_uninstall: is not supported<o:p></o:p> Port 0 is closed<o:p></o:p> Done<o:p></o:p> <o:p> </o:p> Shutting down port 1...<o:p></o:p> Closing ports...<o:p></o:p> mlx5_net: mlx5_os_dev_shared_handler_uninstall: is not supported<o:p></o:p> Port 1 is closed<o:p></o:p> Done<o:p></o:p> <o:p> </o:p> Bye...<o:p></o:p> <o:p> </o:p> Kind regards,<o:p></o:p> Robert<o:p></o:p> </div> </body> </html>
