Subject: [dpdk-dev] DPDK Shared lib: No Ethernet ports
Date: Fri, 7 Sep 2018 14:18:07 +0000 [thread overview]
Message-ID: <DM5PR0101MB2954CC60A1266503E8B4139C87000@DM5PR0101MB2954.prod.exchangelabs.com> (raw)
Hello,
I recently started working with DPDK and gone through the initial steps of getting source code installed and trying out few examples. To integrate DPDK with our product, I need to build the share-lib version of DPDK.
I run into an issue when I build DPDK as shared, I don't see this issue when DPDK is built as static. DPDK built with default configuration, I can run the examples and get expected results. When built as shared, EAL detects no Ethernet ports.
I am building shared-lib version using steps below:
. switch the CONFIG_RTE_BUILD_SHARED_LIB to y in the config/common_base
. make config T=x86_64-native-linuxapp-gcc
. make install T=x86_64-native-linuxapp-gcc
. export RTE_SDK=$HOME/dpdk-18.08
. export RTE_TARGET=x86_64-native-linuxapp-gcc
. build examples.
. Set LD_LIBRARY_PATH to point to $HOME/dpdk-18.08/ x86_64-native-linuxapp-gcc/lib
I am using Intel I350 Quad port NIC, and have switched to uio_pci_generic driver =>
Network devices using DPDK-compatible driver
============================================
0000:06:00.0 'I350 Gigabit Network Connection 1521' drv=uio_pci_generic unused=igb
0000:06:00.1 'I350 Gigabit Network Connection 1521' drv=uio_pci_generic unused=igb
0000:06:00.2 'I350 Gigabit Network Connection 1521' drv=uio_pci_generic unused=igb
0000:06:00.3 'I350 Gigabit Network Connection 1521' drv=uio_pci_generic unused=igb
When I run any examples, I get error 'No Ethernet ports'.
root:l2fwd$./build/l2fwd
EAL: Detected 6 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: No free hugepages reported in hugepages-1048576kB
EAL: Probing VFIO support...
MAC updating enabled
EAL: Error - exiting with code: 1
Cause: No Ethernet ports - bye
Interestingly, same code base built with 'CONFIG_RTE_BUILD_SHARED_LIB=n' works just fine. The ports get detected correctly and I can run all the examples and applications.
Your help is appreciated.
Regards,
Chai.
