HI,
I have problem running helloworld example. The OS hangs and the only way
forward is to poweroff the box.
DPDK version 16.11.1
OS: Ubuntu 16.04 and 14.04
NICs:
18:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network
Connection (rev 03)
24:00.0 Ethernet controller: Intel Corporation I210 Gigabit Network
Connection (rev 03)
The problem only appears when I have two NICs present. If I bind at
least one of them to uio_pci_generic and run helloworld the OS hangs.
If I try to use igb_uio the system hangs when binding the device.
I have narrowed it down a bit. The OS hangs when
e1000_get_media_type_82575 is executed. Line: ctrl_ext =
E1000_READ_REG(hw, E1000_CTRL_EXT);
That line is reading memory mapped from resource0 of the device.
I have reproduced behaviour just by binding the device to
uio_pci_generic and putting it in "bus master" mode and the reading from
it's resour0.
The behaviour is not reproducible with just one NIC in place. Also if
the devices use igb driver and are in "bus master" I can read from
resource0.
Has anyone encountered similar problem?
Cheers,
Michal

Michal,
Could you post up the output of 'lspci -v' for the two cards?
('lspci -v -s 18:00' and 'lspci -v -s 24:00' should do it).
I'm interested in the "Memory at" output.
I'm using a board here with some i211's with Ubuntu 16.04 and DPDK
16.11.1. All OK so far with igb_uio and helloworld.
Regards,
Dave.

Hi Michal,
When I bind my interfaces to igb_uio, I maintain the bus master
flag. Can you describe the hardware layout? Are you using any kind of
PCI multiplexer/riser?
Also, what is the output to 'lcpci -t'? That might give us some
additional interesting information.
Regards,
Dave.

Hi,
I do not use any PCI riser or multiplexer. I have 4 PCIe slots.
1) PCIe x1 - NIC1 (24:00)
2) PCIe x16 - Graphics card
3) PCIe x1 - disabled
4) PCIe x4 - NIC2 (18:00)
Output of lscpi is:

Michal,
Looks OK to me. At this point I don't know what's causing your
issue. And it's likely that if you switched those NICs into a more
modern server (the Z200 is quite old at this stage), it's likely that
everything would just work. All I can suggest at this stage is to maybe
get your hands on a PCIe x1 GFX card to free up the x16 slot, and try
using the gen2 x16 and the x4 for the NICs.
Dave.

Hi Dave,
Yes this is pretty old box. I'll try your suggestion as soon as I get x1 graphics card and let you know.
Thanks for help.

Hi Dave,
I have tried your suggestion and it works if one NIC is x16 and the other in x4.
Thanks again,

Michal,
I looked a bit deeper into the specs of the HP-Z200 workstation. It
has only 1 PCI gen2, and the rest are PCI gen1. Only one of the 16x
slots is gen2.
Could you confirm in which slots a single NIC will work? You can use
"lspci -vvv -s 18:00 | grep LinkSta" to see the speeds when its installed.
Does a single NIC work in all slots?
Does it only work on the Gen2 16x slot?
If you put 2 NICS in 2 gen1 slots, do any of them work?
Regards,
Dave.

Ignore this mail :)
I sent it before you replied saying the gen2 slot is used by the
graphics card.
I'll look at the lspci -t output now.
