During the traffic test, TX adapter showed starvation due to Rx adapter processing on the same dpdk-core 03 and dropped the 41412 packets after 154655 tx_retry. So, I expect I have to assign TX/RX adapter on each dpdk-core to prevent starvation and packet drop. Are those tx_retry and tx_dropped packet due to RX adapter packet processing? Is it possible to separate TX/RX adapter into different dpdk-core? ========[ TX adapter stats ]======== tx_retry: 154655 tx_packets: 438771 tx_dropped: 41412 < eventdev_dump.txt > ========[ Services ]======== qdispatch_service_id : 0 txa_service_id : 1 rxa_service_id : 2 edk_service_id : 3 timer_service_id : 4 timer_adapter_service_id: 5 Service Cores Summary dpdk-core 01: PDCP Fastpath Plugin control function thread dpdk-core qu-dispat txadapter rxadapter edk tmr tmr-adapt 03 0 770574949 770574948 0 0 0 05 816421027 0 0 816421571 816421571 816421571 07 896307282 0 0 896307828 896307828 0 09 899213296 0 0 899213687 899213687 0 11 889323680 0 0 889323871 889323871 0 13 897300534 0 0 897300686 897300686 0 15 891124716 0 0 891124811 891124811 0 17 896336177 0 0 896336212 896336211 0 19 895461845 0 0 895461846 895461846 0 ========[ Event dev port 0 ~ 10 xstats ]======== - packet flow: f1u -> s1u one way midhaul_ker -> midhaul_edk -> backhaul_edk -> backhaul_ker port 09 Rx adapter -> port 07 -> port 06 -> port 08 -> port 09 Tx adapter port 00: dpdk-core 05, worker_core // queue-dispatcher, edk, timer port 01: dpdk-core 07, worker_core // queue-dispatcher, edk, timer port 02: dpdk-core 09, worker_core // queue-dispatcher, edk, timer port 03: dpdk-core 11, worker_core // queue-dispatcher, edk, timer port 04: dpdk-core 13, worker_core // queue-dispatcher, edk, timer port 05: dpdk-core 15, worker_core // queue-dispatcher, edk, timer port 06: dpdk-core 17, worker_core // queue-dispatcher, edk, timer port 07: dpdk-core 19, worker_core // queue-dispatcher, edk, timer port 08: TX adapter, dpdk-core 03 // packet transmission port 09: RX adapter, dpdk-core 03 // packet receiving port 10: Event timer adapter // tmr-adapter BR/Jaeeun -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
