an: port attach failed
Product: DPDK
Version: 25.07
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: testpmd
Assignee: [email protected]
Reporter: [email protected]Target Milestone: ---
Environment
===========
dpdk-25.11.0-rc1: 39b54f2dcf44ad1f91eabc7080cd5dea763607fd
OS: Ubuntu 24.04.3 LTS/6.8.0-79-generic
Compiler: gcc version 13.3.0
Hardware platform: Hardware platform: Intel(R) Xeon(R) 6767P CPU @ 2.4GHz NIC hardware: mev
APF: Intel Corporation Device [8086:1452]
CPF: Intel Corporation Device [8086:1453]
NIC firmware:
ci-ts.release.2.0.0.11126

Test Setup
Steps to reproduce
==================
1. create 2 vfs on apf
echo 2 > /sys/bus/pci/devices/0000\:15\:00.0/sriov_numvfs
2. unbind cpf./usertools/dpdk-devbind.py -u 0000:15:00.6
3. start testpmd without any port x86_64-native-linuxapp-gcc/app/dpdk-testpmd -l 1-3 -n 4 -- -i
4. bind cpf to vfio-pci./usertools/dpdk-devbind.py -b 0000:15:00.6
5. testpmd attach port
testpmd> port attach 0000:15:00.6,vport=[0-1],representor=vf[0,1],flow_parser=./refpkg.json
Results:
========
Attaching a new port...
EAL: Using IOMMU type 1 (Type 1)CPFL_INIT: cpfl_flow_init(): flow module is not initialized Error during enabling promiscuous mode for port 0: Operation not supported - ignore
Port 0 is attached. Now total ports is 1
Done

app/testpmd: canonicalize short PCI name format
when providing short format PCI device names in devargs (e.g. "08:00:0") it is converted and stored as long format. however when attach_port is called from testpmd, the user might provide a short format, which will be passed to find_device with a comparison function that simply compare strings, which will cause find_device not to find any device.
This fix canonicalize the user provided string before it is being passed to find_device.
