Bug ID: 1963
Summary: hotplug_mp: attach the share device failed in
secondary processe
Product: DPDK
Version: 25.07
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: examples
Assignee: dev@dpdk.org
Reporter: yex.chen@intel.com
Target Milestone: ---
Environment
===========
DPDK version: f77bc8767a952cf833fc9c85d6b5b8d77d39a5da
version: 26.07.0-rc2
OS: Rhel9.6 (Plow)/5.14.0-570.12.1.el9_6.x86_64
Compiler: gcc version 11.5.0 20240719
Hardware platform: Intel(R) Xeon(R) 6767P
NIC hardware: Intel Corporation Ethernet Controller XL710 for 40GbE QSFP+
[8086:1583]
NIC firmware:
driver: vfio-pci
kdriver: i40e-2.30.18
firmware-version: 9.57 0x8001037b 1.4002.0
Test Setup
Steps to reproduce
==================
1. Build hotplug_mp
CC=gcc meson -Dlibdir=lib --default-library=static x86_64-native-linuxapp-gcc
-Dmax_lcores=256
ninja -C x86_64-native-linuxapp-gcc
meson configure -Dexamples=multi_process/hotplug_mp x86_64-native-linuxapp-gcc
ninja -C x86_64-native-linuxapp-gcc
2. bind pf to i40e
usertools/dpdk-devbind.py --force --bind=i40e 0000:da:00.0
3. Start dpdk-hotplug_mp as primary then secondary
x86_64-native-linuxapp-gcc/examples/dpdk-hotplug_mp -l 1-2 -n 4 -a
0000:da:00.0 --proc-type=auto
4. Bind the port to vfio-pci
usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:da:00.0
5. Attach the physical device from primary, check primary and secondary
processes attach the share device
example> attach 0000:da:00.0
example> list
Results:
========
the primary processe attach the share device successfully,
but the secondary processe attach the share device failed
example> list
list all etherdev
Expected Result:
================
the primary and secondary processes attach the share device successfully
example> list
list all etherdev
0 0000:da:00.0

dev: skip multi-process in hotplug
If multi-process is disabled ({}no-shconf/{-}-in-memory),
there is no need to build a multi-process message.
