[dpdk-users] Not able to access /dev/uioX from inside LXC
There were two issues w.r.t the above problem * The uioX major number is not fixed across machine reboots - so I had to keep two-three major numbers in devices.allow section to do this. * The sysfs was mounted as read-only file system. When I remounted it as read-write, all problems went away. I could access 40G ports from inside LXC container.

[dpdk-users] DELOCK QSFP cables supported?
I have Intel XL710 Cards on my server. When I try to bring them up, "rte_eth_dev_start" is returning "-95" (not supported). When I probed through GDB, I found that i40e driver is returning "I40E_ERR_UNKNOWN_PHY" for the plugged in cable. Does anybody know whether this is supported or not? Thanks, -nagp

[dpdk-users] Compiling DPDK 16.07 with shared option is failing..
I am not sure why it complains about "rte_eth_bond_8023ad_conf_get at DPDK_2.0" when I cam compiling for 16.07. Anyways, if I change the symbol names, the compilation goes through fine. -nagp On Thu, Nov 10, 2016 at 1:53 PM, Nagaprabhanjan Bellaru < nagp.lists at gmail.com> wrote: > Hi, > > I am compiling DPDK as part of VPP (Cisco).

[dpdk-users] Compiling DPDK 16.07 with shared option is failing..
Hi, I am compiling DPDK as part of VPP (Cisco). It has rte_timer etc. turned off. I enabled it and stumbled on this error. DPDK compilation is invoked by VPP. -nagp On Thu, Nov 10, 2016 at 1:48 PM, Thomas Monjalon wrote: > 2016-11-10 10:37, Nagaprabhanjan Bellaru: > > I found that librte_timer was not enabled and so the compilation failed. > > When I enabled the same, it went ahead and failed at a different place > > while compiling librte_pmd: > > > > -- > > gcc -pie -fPIC > > -L/home/ubuntu/development/libfwdd/src/platform/vpp/vpp/ > build-root/install-vpp_debug-native/dpdk/lib > > -Wl,-g -shared rte_eth_bond_api.o rte_eth_bond_pmd.o rte_eth_bond_args.o > > rte_eth_bond_8023ad.o rte_eth_bond_alb.o -z defs -lrte_mbuf -lethdev > > -lrte_eal -lrte_kvargs -lrte_cmdline -lrte_mempool -lrte_ring > > -Wl,-soname,librte_pmd_bond.so.1.1 -o librte_pmd_bond.so.1.1 > > /usr/bin/ld: librte_pmd_bond.so.1.1: version node not found for symbol > > rte_eth_bond_8023ad_conf_get at DPDK_2.0 > > /usr/bin/ld: failed to set dynamic section sizes: Bad value > > collect2: error: ld returned 1 exit status > > -- > > What are you changing in the default configuration? > Which commands are you using to compile? >
[dpdk-users] Compiling DPDK 16.07 with shared option is failing..
I found that librte_timer was not enabled and so the compilation failed. When I enabled the same, it went ahead and failed at a different place while compiling librte_pmd: -- gcc -pie -fPIC -L/home/ubuntu/development/libfwdd/src/platform/vpp/vpp/build-root/install-vpp_debug-native/dpdk/lib -Wl,-g -shared rte_eth_bond_api.o rte_eth_bond_pmd.o rte_eth_bond_args.o rte_eth_bond_8023ad.o rte_eth_bond_alb.o -z defs -lrte_mbuf -lethdev -lrte_eal -lrte_kvargs -lrte_cmdline -lrte_mempool -lrte_ring -Wl,-soname,librte_pmd_bond.so.1.1 -o librte_pmd_bond.so.1.1 /usr/bin/ld: librte_pmd_bond.so.1.1: version node not found for symbol rte_eth_bond_8023ad_conf_get at DPDK_2.0 /usr/bin/ld: failed to set dynamic section sizes: Bad value collect2: error: ld returned 1 exit status -- I see that the symbol is present in drivers/net/bonding, but I am not sure how to fix this error.

Hi, I am compiling DPDK with "CONFIG_RTE_BUILD_SHARED_LIB=y". However, when I compile, it is failing at: -- gcc -pie -fPIC -L/home/ubuntu/development/libfwdd/src/platform/vpp/vpp/build-root/install-vpp_debug-native/dpdk/lib -Wl,-g -shared rte_sched.o rte_red.o rte_approx.o rte_reciprocal.o -z defs -lm -lrt -lrte_eal -lrte_mempool -lrte_mbuf -lrte_timer -Wl,-soname,librte_sched.so.1.1 -o librte_sched.so.1.1 /usr/bin/ld: cannot find -lrte_timer -- I can see that librte_timer is not compiled yet, however librte_sched depends on it - is there any workaround for this issue? Can I change the order somewhere? Thanks, -nagp
[dpdk-users] Not able to access uio0/device/config from LXC
I have followed the steps mentioned in this thread: to create a uio0, but EAL complains about the following: -- EAL: Cannot open /sys/class/uio/uio0/device/config: Permission denied EAL: Error - exiting with code: 1 Cause: Requested device :00:19.0 cannot be used -- even though I run as a root user and have all the rw permissions. Can anybody tell me what else I could be missing? Thanks, -nagp
[dpdk-users] Not able to detect Intel EC I218-V (rev 03)
Hello, Using setup.sh (available in tools folder) I have bound eth0 (which is of Intel EC I218-V make) to igb_uio module (which I can see with dpdk_nic_bind.py --status output): -- Network devices using DPDK-compatible driver :00:19.0 'Ethernet Connection (3) I218-V' drv=igb_uio unused= Network devices using kernel driver === -- However, when I run any sample application, it complains that there are no ethernet ports: -- EAL: Error - exiting with code: 1 Cause: No available NIC ports! -- If I give a --vdev=eth_pcap0,iface=eth0, then it picks it. Am I missing something? I hope this Intel card is supported by DPDK. Thanks, -nagp
