Hi,

The PCI addresses are known.
When I start my DPDK application, it starts up properly and assigns the
port numbers to them as 0, 1, 2, 3 expectedly.
However, is there a way I can force that a particular PCI address should be

Hi,
While trying to port some code to VPP (which uses DPDK as the backend
driver), I am running into a problem that calls to API's like
rte_timer_subsystem_init, rte_hash_create are failing while allocation
of memory.
This is presumably because VPP inits the EAL with the following arguments --

should be up to the
application to use the API more efficiently, it should not mean that
the usecase should stop working altogether if somebody polls for 1

Hi guys,
I have a VM on top of QEMU/KVM hypervisor. Guest and Host are both Fedora 18.
I am using 82599 NIC with SRIOV based VF's in the VM.
In VM I am running a DPDK based application which uses the VF.
Now I have to do a live migration of the running VM from one physical machine
to the other.
Hi Bruce,
Thanks, this was very useful information.

Hi guys,
The DPDP programmer's guide mentions -
===
The EAL also supports an auto-detection mode (set by EAL --proc-type=auto flag),
whereby an Intel(r) DPDK process is started as a secondary instance if a primary
instance is already running.

So does this mean that if I have a DPDK exe foo.o
Hi,
So if I have multiple queues and was using ETH_MQ_RX_NONE (and therefore
utilizing RSS), it will stop working for me now after this patch ?

Thanks Vladimir !
That seems to be the issue. Better to parse it by hand right now instead of
depending on ol_flags.

Hi guys,
I am facing a peculiar issue with the usage of struct rte_mbuf-> ol_flags field
in the rte_mbuf when I receive the packets with the rte_eth_rx_burst function.
I use the ol_flags field to identify whether is an IPv4 or IPv6 packet or not
thus -

Hi Pepe,
Ofcourse a simple cast will not suffice.
Please look the rte_mbuf structure in the header files and let me know if you
still have the confusion.
There is a header and payload. Your raw frame will go in the payload.

Did you follow the step of applying the mac to each of the virtual function as

And ofcourse the src mac of your packets should be 'that' mac as set above.

Hi,
I have used DPDK1.4 and DPDK1.5 and the packets do fan out nicely on the rx

Hi Alexander,
Regarding your following statement --
"
The only drop counter quickly increasing in the case of pure ACK flood is
ierrors, while rx_nombuf remains zero.
"
Can you please explain the significance of "ierrors" counter since I am not
familiar with that.
Further, you said you have 4
eader files of
rte than what the library was built with based on the compiler flags.

Hi Pepe,
How about this -- compile the libraries yourself and then link your application
with them just like the original usecase where you find the problem.
If this works, then the problem is with the precompiled libraries you were
picking from somewhere.

is a pretty neat use of refcnt. I wonder if this usecase should be

I have a feature request in the PMD.
Today, when I want to send a packet out, I hand over an mbuf to the PMD API.
The PMD API then takes care of transferring the data and free's the mbuf to the

What I am looking for is a facility that I should be able to specify somewhere

Hi Jyoti,
You can configure the number of tx and rx queues via the software when you are
calling the rte_eth_dev_configure.
However you cannot allocate more than what the NIC supports. But you can
allocate less ofcourse.
Typically the queues are used so that independent cores can do tx and rx o
Hi Jyoti,
You must carefully analyse your usecase.
Typically each core must run a tight loop (and therefore one thread spawned by
remote launch) which does a while 1 { get packet, service packet }
You should try to build your application around the above paradigm.

Why are you using the kernel driver at all.
Use the DPDK driver to control the PF on the host. The guest would communicate
