Bug ID: 865
Summary: [dpdk-21.11]launch testpmd with "--vfio-intr=legacy"
appears core dumped
Product: DPDK
Version: 21.11
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: testpmd
Assignee: dev@dpdk.org
Reporter: yanx....@intel.com
Target Milestone: ---
Environment:
OS: Ubuntu21.10 kernel driver: 5.13.0-19-generic
Compiler: gcc (Ubuntu 11.2.0-7ubuntu2) 11.2.0
Hardware platform: Intel(R) Xeon(R) Platinum 8280M CPU @ 2.70GHz
NIC hardware: fortpark_BASE-T
Steps to reproduce
# 1. bind nic to vfio-pci
usertools/dpdk-devbind.py --force --bind=vfio-pci 0000:3d:00.0 0000:3d:00.1
# 2. bbuild app and check it
meson configure -Dexamples=link_status_interrupt x86_64-native-linuxapp-clang
ninja -C x86_64-native-linuxapp-clang
ls x86_64-native-linuxapp-clang/examples/dpdk-link_status_interrupt
# 3. launch testpmd
x86_64-native-linuxapp-clang/examples/dpdk-link_status_interrupt -l 1,2,3,4
-n 4 --file-prefix=dpdk_29738_20211027174729 --vfio-intr=legacy -- -p 0x3
