pci_unbind.py failure

pci_unbind.py failure

[Jyotiswarup Raiturkar]

Hello

I'm trying to install DPDK on my laptop.

I have 82579LM NIC which i'm trying to bind to the igb_uio driver. I get
the following error

# ./tools/pci_unbind.py --status

Network devices using IGB_UIO driver
====================================
<none>

Network devices using kernel driver
===================================
0000:00:19.0 '82579LM Gigabit Network Connection' if=eth0 drv=e1000e
unused=

<none>


# ./tools/pci_unbind.py --force --bind=igb_uio 00:19.0
Error: bind failed for 0000:00:19.0 - Cannot bind to driver igb_uio
Error: unbind failed for 0000:00:19.0 - Cannot open
/sys/bus/pci/drivers//unbind

After this, the --status shows this :

# ./tools/pci_unbind.py --status

My kernel version is 3.5.0-23-generic ( Ubuntu 12.04.2 LTS). I heard about
an UIO bug in 3.10; is this the same bug i;m hitting?

Thanks
Jyoti

I can't find the 82579LM listed on
http://dpdk.org/doc/nics
or in
lib/librte_eal/common/include/rte_pci_dev_ids.h

My guess is that your NIC is not supported.

No, the bug you mention prevented the correct registration of the second
and subsequent ports bound to igb_uio. The first port bound to igb_uio
was working fine.

Thanks for the quick reply. I saw some definitions of e1000_phy_82579 hence
I thought (hoped) the NIC would be supported. I will try to run my dpdk app
inside a VM with an emulated e1000 NIC (just to test the code ..).

Thanks

As a general rule, even if you find references to a NIC in the poll mode
drivers, if it's not listed in lib/librte_eal/common/include/rte_pci_dev_ids.h
then consider the NIC as not supported.

Good luck with the VM,

hi

I got my application running inside a vm (vmplayer) where the VM emulates a
e1000 NIC (82545EM). But rte_eth_dev_count() seems to return 0.. From the
website looks like it's a supported NIC . My lspci and pci_ubind status is
below. Any pointers?

Hi,

How are you using it? I've successfully used it with vbox.

Hi Jyotiswarup,

Did you initialized all the relevant parts before
(rte_eal_init(), rte_pmd_init_all() and don't forget rte_eal_pci_probe())?

Daniel

Re: pci_unbind.py failure

[Vladimir Medvedkin]

Hi all,

I have faced with similar problem on my real environment with 82599 nic.
Looks like in some cases rte_eth_dev_count() return 0 instead of real
number of igb_uio binded ports. After restarting app several times
rte_eth_dev_count() return real number of ports and continue execute
normaly.

Re: pci_unbind.py failure

[Jyotiswarup Raiturkar]

Hi all

Hi

I'm using vmware player , i've using ethernet1.virtualDev = "e1000"

Yes I do rte_eal_init() and then rte_eal_pci_probe().  I'm not using
rte_pmd_init_all() ; not sure what it does.. Also FYI i'm using DPDK 1.4.1r0

I've finally got real hardware too, will try on the same and update the
thread..

Regards
Jyoti

Re: pci_unbind.py failure

[Jose Gavine Cueto]

Hi Jyotiswarup,

Based on my experience and little knowledge on the code, rte_pmd_init_all
registers your poll-mode driver (em in this case) and sets the device
initialization function.  rte_eal_pci_probe will then probe for pci devices
and then initialize their corresponding drivers.  These initialization will
increment the number of usable ports (e.g. e1000) and also the value that
is returned by rte_eth_dev_count.

I think that without calling rte_pmd_init_all, rte_eal_pci_probe will fail
unless you have a specialize routine that sets the initialization function
of your driver.

Cheers,
Pepe
