charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Hi, anyone has similar issue? dpdk qede pmd driver does not work in Debian Bookworm. dpdk-testpmd cannot = receive any packet due to nombuf. This happens to both kernel driver vfio-p= ci and uio_pci_generic. However (1) Linux kernel's qede driver works fine. (2) The Qlogic qede card and dpdk-testpmd works in Debian Bullseye. (3) dpdk-testpmd works fine with other drivers (i40e, ixgbe) Here are some logs: show port stats all ######################## NIC statistics for port 0 #####################= ### RX-packets: 0 RX-missed: 9364844 RX-bytes: 0 RX-errors: 0 RX-nombuf: 9364844 TX-packets: 0 TX-errors: 0 TX-bytes: 0 Throughput (since last show) Rx-pps: 0 Rx-bps: 0 Tx-pps: 0 Tx-bps: 0 #########################################################################= ### show port info all ********************* Infos for port 0 ********************* MAC address: F4:E9:D4:F2:38:98 Device name: 0000:d8:00.0 Driver name: net_qede Firmware-version: 8.40.33.0 MFW: 8.40.31.0 Connect to socket: 1 memory allocation on the socket: 1 Link status: up Link speed: 40 Gbps Link duplex: full-duplex Autoneg status: On MTU: 1500 Promiscuous mode: enabled Allmulticast mode: disabled Maximum number of MAC addresses: 512 Maximum number of MAC addresses of hash filtering: 0 VLAN offload: strip off, filter off, extend off, qinq strip off Hash key size in bytes: 40 Redirection table size: 128 Supported RSS offload flow types: ipv4 ipv4-tcp ipv4-udp ipv6 ipv6-tcp ipv6-udp vxlan geneve Minimum size of RX buffer: 1024 Maximum configurable length of RX packet: 9672 Maximum configurable size of LRO aggregated packet: 0 Current number of RX queues: 4 Max possible RX queues: 32 Max possible number of RXDs per queue: 32768 Min possible number of RXDs per queue: 128 RXDs number alignment: 128 Current number of TX queues: 4 Max possible TX queues: 32 Max possible number of TXDs per queue: 32768 Min possible number of TXDs per queue: 256 TXDs number alignment: 256 Max segment number per packet: 255 Max segment number per MTU/TSO: 18 Device capabilities: 0x0( ) Device error handling mode: none testpmd> show port info 1 =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D kernel and driver information fs4240-87-87:~# uname -r 6.1.0-17-amd64 ii dpdk 22.11.4-1~deb12u1 ii librte-net-qede23:amd64 22.11.4-1~deb12u1 d8:00.0 Ethernet controller: QLogic Corp.
