Regards, Asaf Penso From: Antoine POLLENUS <a.pollenus@deltacast.tv> Sent: Thursday, April 28, 2022 3:25 PM To: users@dpdk.org Subject: [ConnectX 6Dx]Issue using Tx scheduling feature in DPDK Hello, DPDK Version: 21.11 Firmware version : 22.32.1010 MLNX_OFED version: MLNX_OFED_LINUX-5.5-1.0.3.2-ubuntu20.04-x86_64 We are trying to use the DPDK tx scheduling feature on a ConnectX6 DX adapter. We experience some issues with the feature not working. The test is using Test-pmd in txonly mode. Here are the command used: sudo ./dpdk-testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=1 --eth-peer=0,01:00:5e:00:00:08 --tx-ip=10.10.1.168,239.0.0.8 testpmd> set fwd txonly testpmd> set burst 64 testpmd> set txtimes 1000000,10000 By doing this I expect the feature working. Am i missing something ? I also added a print in txonly.c and clearly sees that the feature is not enabled dynf = rte_mbuf_dynflag_lookup (RTE_MBUF_DYNFLAG_TX_TIMESTAMP_NAME, NULL); if (dynf >= 0) timestamp_mask = 1ULL << dynf; dynf = rte_mbuf_dynfield_lookup (RTE_MBUF_DYNFIELD_TIMESTAMP_NAME, NULL); if (dynf >= 0) timestamp_off = dynf; both function ( rte_mbuf_dynfield_lookup and rte_mbuf_dynflag_lookup) returns -1 I also tried to enabled the feature. testpmd> port config 0 tx_offload send_on_timestamp on but when doing this DPDK tells me that I don't have these offload capabilities Hope you will be able to help me.
