RE: RE: About rte_flow asynchronous API

[Junghan Yoon]

Thank you Zhao.   I tried it, but now mlx5 driver returned error. mlx5_net: [mlx5dr_action_create_generic]: Cannot create HWS action since HWS is not supported It is what I saw in my original code before trying on testpmd. It seems to be an issue from connectX-6 configuration.   Is there anyone ever tried to use asynchronous API with connectX-6? Setting dv_flow_en=2 and dv_esw_en=1 seems not enough. I explored the mlx5 code, and found that rte_flow_configure() queries HCA capability by mlx5dr_cmd_query_caps(). In my case, rte_flow_configure() returned error since caps->wqe_based_update is set by 0.   Is there anyone know how to set this value to non-zero? I already wrote the same question on nvidia forum.   Sincerely, Junghan Yoon   보낸 사람: Bing Zhao 보낸 날짜: 2023년 6월 9일 금요일 오후 10:00 받는 사람: users@dpdk.org; cerot...@gmail.com 제목: RE: About rte_flow asynchronous API   Hi Junghan,   In testpmd, you can easily do it by:   port stop all # or port stop 0   flow configure 0 …… # if there are other port(s) # flow configure Y ……     port start all # or port start 0   With the source code implementation, you can configure it before starting a device.   BR.

I’m trying to use testpmd to test rte_flow with asynchronous API in DPDK 22.11.   I turned on dv_esw_en=1 by echoing switchdev to /sys/class/net/…., and set dv_flow_en to 2 to use connectX-6 HWS (hardware steering). sudo build/app/dpdk-testpmd -a 0000:8a:00.0,dv_flow_en=2 -a 0000:8a:00.1,dv_flow_en=2 -- -i --rxq=1 --txq=1   In the prompt, I typed below flow configure 0 queues_number 1 queues_size 10 counters_number 0 aging_counters_number 0 meters_number 0 flags 0   but it said “Device with port_id=0 already started.”.   I know rte_flow_configure() call should be in the middle of rte_eth_dev_configure() and rte_eth_dev_start(). So, I run testpmd by below to postpone device start, sudo build/app/dpdk-testpmd -a 0000:8a:00.0,dv_flow_en=2 -a 0000:8a:00.1,dv_flow_en=2 -- -i --rxq=1 --txq=1 --disable-device-start   However, now not only rte_eth_dev_start() but also rte_eth_dev_configure() does not start, so it said “Device with port_id=0 is not configured.”.   How can I run rte_flow_configure() between rte_eth_dev_configure() and rte_eth_dev_start() in testpmd? Is there any parameter to postpone only rte_eth_dev_start()?   Sincerely, Junghan Yoon.
