Running the Application ======================= EAL Command-line Options ------------------------ The following are the EAL command-line options that can be used in conjunction with the testpmd, or any other DPDK application. See the DPDK Getting Started Guide for more information on these options. * -c COREMASK Set the hexadecimal bitmask of the cores to run on. * -n NUM Set the number of memory channels to use. * -b, --pci-blacklist domain:bus:devid.func Blacklist a PCI devise to prevent EAL from using it. Multiple -b options are allowed. * -d LIB.so Load an external driver. Multiple -d options are allowed. * -w, --pci-whitelist domain:bus:devid:func Add a PCI device in white list. * -m MB Memory to allocate. See also --socket-mem. * -r NUM Set the number of memory ranks (auto-detected by default). * -v Display the version information on startup. * --xen-dom0 Support application running on Xen Domain0 without hugetlbfs. * --syslog Set the syslog facility. * --socket-mem Set the memory to allocate on specific sockets (use comma separated values). * --huge-dir Specify the directory where the hugetlbfs is mounted. * --proc-type Set the type of the current process. * --file-prefix Prefix for hugepage filenames. * -vmware-tsc-map Use VMware TSC map instead of native RDTSC. * --vdev Add a virtual device, with format "[,key=val, ...]", e.g. --vdev=eth_pcap0,iface=eth2. * --base-virtaddr Specify base virtual address. * --create-uio-dev Create /dev/uioX (usually done by hotplug). * --no-shconf No shared config (mmap'd files). * --no-pci Disable pci. * --no-hpet Disable hpet. * --no-huge Use malloc instead of hugetlbfs. Testpmd Command-line Options ---------------------------- The following are the command-line options for the testpmd applications. They must be separated from the EAL options, shown in the previous section, with a -- separator: .. code-block:: console sudo ./testpmd -c 0xF -n 4 -- -i --portmask=0x1 --nb-cores=2 * -i, --interactive Run testpmd in interactive mode. In this mode, the testpmd starts with a prompt that can be used to start and stop forwarding, configure the application and display stats on the current packet processing session. See the Section 5.0, "Test Runtime Functions" section for more details. In non-interactive mode, the application starts with the configuration specified on the command-line and immediately enters forwarding mode. * -h, --help Display a help message and quit. * -a, --auto-start Start forwarding on init. * --nb-cores=N Set the number of forwarding cores, where 1 <= N <= number of cores or RTE_MAX_LCORE from the configuration file. The default value is 1. * --nb-ports=N Set the number of forwarding ports, where 1 <= N <= number of ports on the board or RTE_MAX_ETHPORTS from the configuration file. The default value is the number of ports on the board. * --coremask=0xXX Set the hexadecimal bitmask of the cores running the packet forwarding test. The master lcore is reserved for command line parsing only and cannot be masked on for packet forwarding. * --portmask=0xXX Set the hexadecimal bitmask of the ports used by the packet forwarding test. * --numa Enable NUMA-aware allocation of RX/TX rings and of RX memory buffers (mbufs). * --port-numa-config=(port,socket)[,(port,socket)] Specify the socket on which the memory pool to be used by the port will be allocated. * --ring-numa-config=(port,flag,socket)[,(port,flag,socket)] Specify the socket on which the TX/RX rings for the port will be allocated. Where flag is 1 for RX, 2 for TX, and 3 for RX and TX. * --socket-num=N Set the socket from which all memory is allocated in NUMA mode, where 0 <= N < number of sockets on the board. * --mbuf-size=N Set the data size of the mbufs used to N bytes, where N < 65536. The default value is 2048. * --total-num-mbufs=N Set the number of mbufs to be allocated in the mbuf pools, where N > 1024. * --max-pkt-len=N Set the maximum packet size to N bytes, where N >= 64. The default value is 1518. * --eth-peers-configfile=name Use a configuration file containing the Ethernet addresses of the peer ports. The configuration file should contain the Ethernet addresses on separate lines: XX:XX:XX:XX:XX:01 XX:XX:XX:XX:XX:02 ... * --eth-peer=N,XX:XX:XX:XX:XX:XX Set the MAC address XX:XX:XX:XX:XX:XX of the peer port N, where 0 <= N < RTE_MAX_ETHPORTS from the configuration file. * --pkt-filter-mode=mode Set Flow Director mode where mode is either none (the default), signature or perfect. See the Section 5.6, "Flow Director Functions" for more detail. * --pkt-filter-report-hash=mode Set Flow Director hash match reporting mode where mode is none, match (the default) or always. * --pkt-filter-size=N Set Flow Director allocated memory size, where N is 64K, 128K or 256K. Sizes are in kilobytes. The default is 64. * --pkt-filter-flexbytes-offset=N Set the flexbytes offset. The offset is defined in words (not bytes) counted from the first byte of the destination Ethernet MAC address, where N is 0 <= N <= 32. The default value is 0x6. * --pkt-filter-drop-queue=N Set the drop-queue. In perfect filter mode, when a rule is added with queue = -1, the packet will be enqueued into the RX drop-queue. If the drop-queue does not exist, the packet is dropped. The default value is N=127. * --crc-strip Enable hardware CRC stripping. * --enable-rx-cksum Enable hardware RX checksum offload. * --disable-hw-vlan Disable hardware VLAN. * --enable-drop-en Enable per-queue packet drop for packets with no descriptors. * --disable-rss Disable RSS (Receive Side Scaling). * --port-topology=mode Set port topology, where mode is paired(the default) or chained. In paired mode, the forwarding is between pairs of ports, for example: (0,1), (2,3), (4,5). In chained mode, the forwarding is to the next available port in the port mask, for example: (0,1), (1,2), (2,0). The ordering of the ports can be changed using the portlist testpmd runtime function. * --forward-mode=N Set forwarding mode. (N: io|mac|mac_retry|mac_swap|flowgen|rxonly|txonly|csum|icmpecho) * --rss-ip Set RSS functions for IPv4/IPv6 only. * --rss-udp Set RSS functions for IPv4/IPv6 and UDP. * --rxq=N Set the number of RX queues per port to N, where 1 <= N <= 65535.
