Hi Thomas/Antoly, We have tried with the below capability to start a DPDK application as a container. --cap-add=NET_ADMIN --cap-add=SYS_RESOURCE --cap-add=SYS_NICE
Still We could see the failures when rte_eali_init() .. 09-06-2021 10:48:37.423583 EAL: NUMA is not supported. *09-06-2021 10:48:37.423895 EAL: alloc_seg(): get_mempolicy: Function not implemented ==> Does this sound like virtual memory is not enough in the running system (because of NUMA not supported )?* 09-06-2021 10:48:37.423910 EAL: Ask a virtual area of 0x200000 bytes 09-06-2021 10:48:37.423919 EAL: Virtual area found at 0x2200200000 (size = 0x200000) 09-06-2021 10:48:37.423933 EAL: attempted to allocate 1 segments, but only 0 were allocated 09-06-2021 10:48:37.423945 EAL: NUMA is not supported. *09-06-2021 10:48:37.427811 EAL: alloc_seg(): mmap() failed: Cannot allocate memory ==> SYS_RESOURCE would suffice here ?* 09-06-2021 10:48:37.427821 EAL: Ask a virtual area of 0x40000000 bytes 09-06-2021 10:48:37.427829 EAL: Virtual area found at 0x140000000 (size = 0x40000000) 09-06-2021 10:48:37.427839 EAL: attempted to allocate 1 segments, but only 0 were allocated 09-06-2021 10:48:37.427847 EAL: error allocating rte services array 09-06-2021 10:48:37.427869 EAL: rte_service_init() failed As for the dpdk options when bringing up our application, --log-level=*:8 --lcores=(0-1)@0 --in-memory -d/usr/lib64/dpdk-19/librte_pmd_ixgbe.so.20.0 -d/usr/lib64/dpdk-19/librte_pmd_e1000.so.20.0 -d/usr/lib64/dpdk-19/librte_pmd_bnxt.so.20.0 --vdev=net_af_packet0,iface=dpbr_100 --vdev=net_af_packet1,iface=asac-in --vdev=net_af_packet2,iface=asac-out *--iova-mode=va ==> will valid here ?* Would assume some of the flags were not enough to run DPDK on top of our environment ? Any memory configuration which needs to be checked for the underlying system ? Please share your thoughts.
