Bug ID: 541
Summary: [dpdk-20.11]
loopback_virtio_user_server_mode/Basic_test_for_packed
_ring_server_mode: loopback throughput is zero
Product: DPDK
Version: 20.11
Hardware: All
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: vhost/virtio
Assignee: dev@dpdk.org
Reporter: yux.ji...@intel.com
Target Milestone: ---
DPDK version:
DPDK commit: 46697431adcba206fd5222361bc73c5cf9042a86
DPDK Comment: test/ring: enhance debug info in failure cases
DPDK Version: 20.11.0-rc0
OS: Ubuntu20.04.1 LTS (Focal Fossa)/5.4.0-47-generic
Compiler: gcc version 9.3.0
Hardware platform: Intel(R) Xeon(R) Platinum 8280M CPU @ 2.70GHz
Test Setup:
Steps to reproduce:
0, Build DPDK with meson & ninja
CC=gcc meson --werror -Denable_kmods=True -Dlibdir=lib
-Dc_args='-DRTE_LIBRTE_PMD_PCAP=1' --default-library=static
x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc -j 110
Test Case 1: Basic test for packed ring server mode
===================================================
1. Launch virtio-user as server mode::
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-2 -n 4 --no-pci
--file-prefix=virtio \
--vdev=net_virtio_user0,mac=00:11:22:33:44:10,path=/tmp/sock0,server=1,queues=1,packed_vq=1
-- -i --rxq=1 --txq=1 --no-numa
>set fwd mac
>start
2. Launch vhost as client mode::
./x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 3-4 -n 4 --no-pci
--file-prefix=vhost \
--vdev 'net_vhost0,iface=/tmp/sock0,client=1,queues=1' -- -i --rxq=1
--txq=1 --nb-cores=1
>set fwd mac
>start tx_first 32
3. Run below command to get throughput,verify the loopback throughput is not
zero::
testpmd>show port stats all
Show the output from the previous commands:
dut.10.240.183.214_vhost: show port stats all
dut.10.240.183.214_vhost:
######################## NIC statistics for port 0 ########################
RX-packets: 0 RX-missed: 0 RX-bytes: 0
RX-errors: 0
RX-nombuf: 0
TX-packets: 0 TX-errors: 0 TX-bytes: 0
Throughput (since last show)
Rx-pps: 0 Rx-bps: 0
Tx-pps: 0 Tx-bps: 0
############################################################################
[Expected result]
lookback throughput should not be zero.

net/virtio-user: support vhost status setting
This patch adds support for VHOST_USER_SET_STATUS
request. It is used to make the backend aware of
Virtio devices status update.
It is useful for the backend to know when the Virtio
driver is done with the Virtio device configuration.
