No probed ethernet devices /DPDP 1.7.1 in Fedora 21

No probed ethernet devices /DPDP 1.7.1 in Fedora 21

[sothy shan]

Hello!

I am playing with DPDK 1.7.1 in Fedora.

When I do like this:

export RTE_SDK=$(pwd)export RTE_TARGET="x86_64-ivshmem-linuxapp-gcc"
make install T="$RTE_TARGET"

It worked. Means Testpmd is running.

When I run as mentioned below:

make CONFIG_RTE_BUILD_SHARED_LIB=y  install T="$RTE_TARGET"

Build is sucess. But Testpmd gives error.

Error is :

ivshmem is used with QEMU virtual machine.
see http://dpdk.org/doc/guides/prog_guide/ivshmem_lib.html

Try RTE_TARGET="x86_64-native-linuxapp-gcc".

The dpdk ivshmem build assumes the presence of ivshmem devices as plumbed by
qemu virtual guests.  If you don't have a qemu guest running dpdk won't find any
shared memory devices, which is exactly what you are seeing.  That said, even if
you are running qemu guests, IIRC Fedora doesn't enable ivshmem because the code
has some security and behavioral issues still I think.  You'll need to rebuild
qemu to add support for it.

My understanding is that It is problem of enabling
CONFIG_RTE_BUILD_SHARED_LIB=y in make command, I am able to build target of
x86_64-ivshmem-linuxapp-gcc alone without shared_lib flag. I suspect an
error because of shared lib flag.

What exactly do you think that problem is?  You just said in your
origional note that you are able to build the sdk and test apps without issue
(with or without building them as DSO's).  The problem comes in when you run
the app, and I expect you get the same error with both static and dynamic
builds.

The problem seems obvious to me.  DPDK cannot find any ivshmem devices on your
system when it loads (look at the code in rte_eal_ivshmem_init).  The error
message you see gets output if you don't generate an ivshmem_config, which
happens (among a few other reasons), if you don't have any ivshmem devices
created on your system

Do you have any hints for these messsages?

EAL: Error - exiting with code: 1
  Cause: No probed ethernet devices - check that
CONFIG_RTE_LIBRTE_IGB_PMD=y and that CONFIG_RTE_LIBRTE_EM_PMD=y and that
CONFIG_RTE_LIBRTE_IXGBE_PMD=y in your configuration file


Is that with IVSHMEM device or physical devices? I guess it is physical
device problem?

Thank you

Yes, I gave you direction in my last note, its the fact that no ivshmem devices
were found.

This is a false indicator.  If you look at a later version of the code you'll
see that the message has been pruned to just indicate that no probed ethernet
devices were found.  The remainder of the message was there because it used to
be a presumption that a physical devices was in use, which need not be the case.
Like I said before you need an ivshmem driver, which qemu provides, but not in
the current fedora build.

No, its not, you're making this harder than it needs to be.  google qemu and
ivshmem and you'll see.  Heres an article to get you started:

Re: No probed ethernet devices /DPDP 1.7.1 in Fedora 21

[sothy shan]

According to your argument,

I compiled qemu in DPDK OVS as provided with command.

After that, I compiled as stated here.

cd DPDK                     # DPDK sub-directoryexport
RTE_SDK=$(pwd)export RTE_TARGET="x86_64-ivshmem-linuxapp-gcc"
make CONFIG_RTE_BUILD_COMBINE_LIBS=y CONFIG_RTE_BUILD_SHARED_LIB=y
install T="$RTE_TARGET"

Then I try to run the command for testpmd. I got same error. Any idea
where is the mistake? Thanks

Did you run qemu and create an ivshmem device?  Thats why you needed qemu
support so that you could run it and have qemu create a network device that had
a ivshmem interface

Re: No probed ethernet devices /DPDP 1.7.1 in Fedora 21

[sothy shan]

I guess you are completely wrong.

Becasue when I do

make config T=x86_64-ivshmem-linuxapp-gcc
make

Testpmd works.

When I do  with

export RTE_SDK=$(pwd)export RTE_TARGET="x86_64-ivshmem-linuxapp-gcc"
make CONFIG_RTE_BUILD_COMBINE_LIBS=y CONFIG_RTE_BUILD_SHARED_LIB=y
install T="$RTE_TARGET"


I get same error. I guess there are some problems in above two config
variables. I see some email post over some changes.But I didnt get the
point, but working on it.

It is just information for you.


Best regards

Sothy

Are you sure that this syntax is supported by the build system?

As far as I know, RTE_SDK and RTE_TARGET must be defined when building
an external application (like in examples), not when building test-pmd
app which is a sdk built-in.

Also, I'm not sure passing a CONFIG_XYZ=y variable will be properly
taken in account by the build system. Where did you found this syntax?
The proper way is:

  make config T=x86_64-ivshmem-linuxapp-gcc O=my_dir
  ${EDITOR} my_dir/.config
  make O=my_dir

One last comment, please be careful when copy/pasting commands in
mails as there are typos in some of your commands. A reader could
expect that your problem comes from this:

  $ export RTE_SDK=$(pwd)export RTE_TARGET="x86_64-ivshmem-linuxapp-gcc"
  $ echo $RTE_SDK
  /home/userexport

I am tryiting to build DPDK OVS and found  the instruction in
https://github.com/01org/dpdk-ovs/blob/development/docs/01_Installation.md

If I understand the your idea, I should compile and run DPDK OVS
directly rather than DPDK testpmd. Isnt it? I will try now this.

Before, I tries testpmd and then go for DPDK OVS.

I just noticed the syntax is strange, you can check the supported
options here:

http://dpdk.org/doc/guides/prog_guide/dev_kit_build_system.html#makefile-description

I'm not sure the CONFIG_ will be taken in account when generating
rte_config.h (see rte.sdkconfig.mk and scripts/gen-config-h.sh). But
maybe it's not related to your issue.

Olivier

For me, I followed the top leve compilation and compilation went well.
https://github.com/01org/dpdk-ovs/blob/development/docs/01_Installation.md
It means those paremeters are taken into account somewhere.

Now I didnt check testpmd command and directly went to run ovs-dpdk in
Fedora 20 with DPDK OVS 1.2

I am in another problem. I guess it is out of your focus, I just give
you the idea.
