Subject: [dpdk-dev] [PATCH 1/3] app/testpmd: fix forwarding configuration when DCB test
Date: Fri, 5 Mar 2021 18:22:19 +0800 [thread overview]
Message-ID: <1614939741-63927-2-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1614939741-63927-1-git-send-email-oulijun@huawei.com>
From: Huisong Li <lihuisong@huawei.com>
Currently, 'nb_fwd_lcores' value are both adjusted based on
'nb_fwd_streams' in rss/simple/icmp_echo_fwd_config_setup. But the
operation is lack for dcb_fwd_config_setup, which may lead to a
bad events where multiple polling threads operate on the same
queue. As a result, various possible exceptions will occur. The
procedure is as follows:
startup testpmd app as follows:
testpmd> port stop all
testpmd> set nbcore 8
testpmd> port config 0 dcb vt off 4 pfc on
testpmd> port config all rxq 16
testpmd> port config all txq 16
testpmd> port start all
testpmd> set fwd mac

RX P=0/Q=7 (socket 0) -> TX P=0/Q=7 (socket 0) peer=02:00:00:00:00:00
Notice: number of rxq and txq in running cmdline are greater than
used nb_tc.
For the DCB forwarding test, each core is assigned on each traffic class
and each core is assigned a multi-stream. Therefore, 'nb_fwd_lcores'
value can be adjusted based on 'total_tc_num' in all forwarding ports.
In addition, after operation of port stop/port start, forwarding
configuration is changed by rss_fwd_config_setup. In "start_port"
function, dcb_test is set to 1 based on dcb_config. So it also
should be cleared when dcb_config is 0.
