[dpdk-dev] lost when learning how to test dpdk

[Jan Viktorin]

Hello all,

I am learning how to measure throughput with dpdk. I have 4 cores
Intel(R) Core(TM) i3-4360 CPU @ 3.70GHz and two 82545GM NICs connected
together. I do not understand very well, how to setup testpmd.

I've successfully bound the NICs to dpdk:

$ dpdk_nic_bind --status

Network devices using DPDK-compatible driver
============================================
0000:03:00.0 '82545GM Gigabit Ethernet Controller' drv=uio_pci_generic unused=e1000
0000:03:02.0 '82545GM Gigabit Ethernet Controller' drv=uio_pci_generic unused=e1000

0000:00:19.0 'Ethernet Connection I217-V' if=eno1 drv=e1000e unused=uio_pci_generic *Active*

Other network devices
=====================
<none>

and then I tried to run testpmd:

sudo ./testpmd -b 0000:03:00.0 -b 0000:03:02.0 -c 0xf -n2 -- --nb-cores=1 --nb-ports=0 --rxd=2048 --txd=2048 --mbcache=512 --burst=512

EAL: lcore 1 is ready (tid=48ffe700;cpuset=[1])
EAL: No probed ethernet devices
EAL: Error - exiting with code: 1
  Cause: Invalid port 0

I tried --nb-ports={0,1,2} but neither of them works. BTW, what does this option it mean? :)
I could not find any description in the docs nor in the help (maybe I've omitted something).


Well, if I manage the testpmd to work I need a packet generator, right? I've downloaded
the dpdk-pktgen. And I am lost again. How can I start it?

After several attempts (mostly trying to use the pktgen-master/slave.sh, what is
their purpose?), the most "successful" output was:

...
EAL: Detected lcore 0 as core 0 on socket 03 handles port 1 rx & core 4 handles port 0-7 tx

1: [./pktgen(rte_dump_stack+0x16) [0x4c3946]]

I'd like to run a simple scenario, just sending packets from one NIC to the other (or
something similar) and measure the throughput. Could you please help me?

Jan Viktorin

The -b option black lists your PCI devices, you don't need those. The 
--nb-ports is of course the number of ports, it cannot be 0.

You either don't have hugepages or there aren't any free left.

Hi,

thanks for reply. I could see those docs but it does not help me a lot.
I still do not understand very well the principle of the tool. How it
chooses the NICs to use? Previously I confused -b in dpdk_nic_bind and
testpmd. They have somehow opposite meaning. I can start testpmd now,
however, it does ot probe any NIC. I've tried -w to whitelist certain
NICs but with no success.

$ dpdk_nic_bind --status

NICs may not be supported by PMD drivers yet. Do "lspci -nn" and check the
device-id.  Adding support in PMD should not be a problem, but I am not
sure on support since there is End of Life listed on Intel Website

http://ark.intel.com/products/4964/Intel-82545GM-Gigabit-Ethernet-Controller

DPDK doesn't bind Active NIC, support for I217-V in PMD is being tested
currently.

Re: [dpdk-dev] lost when learning how to test dpdk

[Jan Viktorin]

The 82545 is listed at http://dpdk.org/doc/nics and I can see it in
rte_pci_dev_ids.h/e1000_hw.h:

196 #define E1000_DEV_ID_82545GM_COPPER           0x1026

$ lspci -nn
...
03:00.0 Ethernet controller [0200]: Intel Corporation 82545GM Gigabit Ethernet Controller [8086:1026] (rev 04)
03:02.0 Ethernet controller [0200]: Intel Corporation 82545GM Gigabit Ethernet Controller [8086:1026] (rev 04)

However, it is rev 04 and in e1000_hw.h there is just e1000_82545_rev_3.
But this should not avoid the match (?). Is it possible to grow the verbosity
level of the device matching process in DPDK?

I do not expect any support, I just wanted to use it for sending traffic
at 1 Gbps because there are two such cards mostly unused in my computer.
I did not plan to use I217-V (in fact, I did not expect much from this
integrated NIC and I did not even notice it is an Intel one...).

Check lib/librte_eal/common/include/rte_pci_dev_ids.h, you need to add
device-id via RTE_PCI_DEV_ID_DECL_EM.

Re: [dpdk-dev] lost when learning how to test dpdk

[Jan Viktorin]

OK, I've added the card into RTE_PCI_DEVEM_ID_DECL_EM list.
Much better now:

EAL: Requesting 64 pages of size 2MB from socket 0
EAL: TSC frequency is ~3699995 KHz
EAL: Master lcore 0 is ready (tid=467d78c0;cpuset=[0])
EAL: lcore 1 is ready (tid=3a5ff700;cpuset=[1])
EAL: PCI device 0000:03:00.0 on NUMA socket -1
EAL:   probe driver: 8086:1026 rte_em_pmd
EAL:   PCI memory mapped at 0x7fde44a00000
EAL:   PCI memory mapped at 0x7fde44a20000
PMD: eth_em_dev_init(): port_id 0 vendorID=0x8086 deviceID=0x1026
EAL: PCI device 0000:03:02.0 on NUMA socket -1
EAL:   probe driver: 8086:1026 rte_em_pmd
EAL:   Not managed by a supported kernel driver, skipped
Interactive-mode selected
EAL: Error - exiting with code: 1
  Cause: Creation of mbuf pool for socket 0 failed

I've tried both uio_pci_generic and igb_uio. Is there anything else
I can do about it?

I am attaching patch from M Jay/Cuming (Intel engineers), it's not yet
integrated into DPDK mainline. You need it to fix above mbuf error.
