[dpdk-users] Error in rte_eal_init using dpdk 16.04 and Qlogic (Broadcom) bnx2x driver in a SECONDARY process
Hello David, By looking on driver sources (bnx2x_ethdev.c) assertion `sc->bar[0].base_addr' fail is caused by pci_dev->mem_resource[0].addr == NULL. It means that MMIO mapping of region nr. 0 failed. The reason of this may be print reported on ring level some time before crash: "EAL: memzone_reserve_aligned_thread_unsafe(): memzone already exists RING: Cannot reserve memory." I suspect some memory allocation issue but not 100% sure.

[dpdk-users] EAL: No probed ethernet devices
Hello Upendra, "I have bound Intel 82579V nic with igb_uio and was working on testpmd application and i am not getting any ports for testpmd probably beacuse of EAL: No probed ethernet devices error." Are you sure this device is supported by dpdk? According to NIC's list coming from: http://dpdk.org/doc/nics Intel 82579V is not supported by any PMD. To be 100% sure you may look at dpdk source code - dpdk/lib/librte_eal/common/include/rte_pci_dev_ids.h which doesn't contain 82579V as well. Good news is that your second card - Intel 82540EM is supported by e1000 from dpdk.

[dpdk-users] Minimal dpdk configuration for 2 hosts
Hello Harold, I did investigation and one directional forwarding through 2 hosts connected by one port NIC each is possible indeed. Testpmd with following command line arguments can do that: ? On host1 (as sender): ./testpmd -c 0x3 -n4 -- -i --forward-mode=txonly --port-topology=chained On host2 (as reciever): ./testpmd -c 0x3 -n4 -- -i --forward-mode=rxonly --port-topology=chained ? Anyway still I don't how to run two directional communication. Harold, could you provide commands/command line options for this? Also It seems that? 2 port NIC on every host is required to run basicfwd, rxtx_callbacks and other examples (dpdk gives me print that number of ports must be even). ? Regards, Dawid ? W dniu 2016-03-06 10:30:51 u?ytkownik Harold Demure napisa?: Hello Dawid, I am no expert but a single port should be able to take care of both TX and RX queues. For example, I am currently running two hosts with only one port each and they are able to both send and receive messages. Regards, Harold 2016-03-04 21:47 GMT+01:00 dawid_jurek : Hello, I wonder what is the minimal configuration (in sense on number of NIC ports) to run basic dpdk examples like basicfwd, rxtx_callbacks or forwarding by testpmd for 2 hosts connected directly by Ethernet. Is it possible to perform one directional transmission for some kind of sender-reciever scenario (2 hosts, every host with one port)? It seems that for every kind of transmission between 2 machines I need at least 4 ports (because every port may take care of TX or RX but not both of them at the same time). Is it correct? Regards, Dawid ?
