Bug ID 1261
Summary [dpdk 23.07] the dpdk-testpmd (based on VF) 's throughput is= 0
Product DPDK
Version 23.07
Hardware x86
OS Linux
Status UNCONFIRMED
Severity major
Priority Normal
Component testpmd
Assignee dev@dpdk.org
Reporter yanghliu@redhat.com
Target Milestone --- 

Description of problem:
start a dpdk-testpmd based on VF , do the Moongen Throughput tests, the
dpdk-testpmd throughput is 0=20

Version-Release number of selected component (if applicable):
host:
Ethernet Controller 10-Gigabit X540-AT2
5.14 kernel


How reproducible:
100%

Steps to Reproduce:
1. setup the host kernel option
# grubby --args=3D"iommu=3Dpt intel_iommu=3Don default_hugepagesz=3D1G=
"
--update-kernel=3D`grubby --default-kernel`=20
# reboot

2. setup hugepage number
# echo 20 >
/sys/devices/system/node/node0/hugepages/hugepages-1048576kB/nr_hugepages
# echo 20 >
/sys/devices/system/node/node1/hugepages/hugepages-1048576kB/nr_hugepages

3. create VF and setup VF mac address

# /usr/sbin/ifconfig ens3f0  up
# echo 2 > /sys/bus/pci/devices/0000\:5e\:00.0/sriov_numvfs
# readlink /sys/bus/pci/devices/0000:5e:00.0/virtfn*
# ip link set enp94s0f0 vf 0 mac 88:66:da:5f:dd:02
# dpdk-devbind.py --bind=3Dvfio-pci 0000:5e:10.0
# /usr/sbin/ifconfig ens3f1 up
# echo 2 > /sys/bus/pci/devices/0000\:5e\:00.1/sriov_numvfs
# readlink /sys/bus/pci/devices/0000:5e:00.1/virtfn*
# ip link set enp94s0f1 vf 0 mac 88:66:da:5f:dd:03
# dpdk-devbind.py --bind=3Dvfio-pci 0000:5e:10.1


4. start a dpdk-testpmd on the host
# /usr/local/bin/dpdk-testpmd -l 2,4,6 -n 4  -- --nb-cores=3D2 -i --disable=
-rss
