Hi Marcus,
thank you very much for the hints.
Reusing the clocks of the 10G interface seems to be a good starting point.
Maybe it is necessary to generate a 312.5 MHz clock.
Since I'm not an FPGA expert that experiment will take some time, at least more
than I have expected.
Best regards
Matt

Hi,
Fruits aside, that was a valid question. Cause of bad performance when
combining DPDK with GNU Radio is a topic that needs to be addressed.
My hypothesis regarding the cause was:
DPDK needs few processor cores for itself only. GNU Radio runs a lot of thread
(one thread per block +) and it
Hi Kasim,
The files with extension *.a (static libraries) are source of the
problem. Put the needed libraries without static libraries in a separate
directory, let's say /usr/local/lib/x86_64-linux-gnu/pmds , and change
in the config to:
dpdk-driver=/usr/local/lib/x86_64-linux-gnu/pmds

Hello Meni,
I don't know what is exact reason of the undefined references that you
see. But I can tell you that I'm able to correctly compile UHD-4.2.0.1
with manually compiled DPDK 21.11 on Ubuntu 20.04 and 22.04.
As always with DPDK there's ton of difficulties on the way to set it up
and t
Hello all,
Has anybody tried to use DPDK with USRP X410?
If yes - can you share what was maximal sample rate for a single channel
that you were able to stream over 10G or 100G Ethernet connection
without loss and what was your setup (hardware and software)?
