Hello,

I'm trying to configure UHD to work with DPDK and my Intel X550T NIC. When
running the benchmark_rate UHD example, the x310 drops packets and gives
sequence errors even at lower sample rates. Below is an example of the
output from the script. Have I configured something incorrectly?

Good morning Shane,

Can you verify what Linux kernel you are using? See the bottom section of this KB article: https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD

It looks like I had secure boot enabled. After disabling it
and modifying features as in the article, I'm not getting any sequence
errors or dropped samples! However, my desktop freezes up momentarily while
I run the benchmark. Is this normal with DPDK, or is it a configuration
issue?

It looks like I had secure boot enabled. After disabling it and modifying features as in the article, I'm not getting any sequence errors or dropped samples! However, my desktop freezes up momentarily while I run the benchmark. Is this normal with DPDK, or is it a configuration issue?

I think the frozen screen problem occurred because I set isolcpus in
/etc/default/grub for the DPDK cores in my uhd.conf file. After removing
that and rebooting, everything proceeds smoothly.

Thank you for your help!

For some reason, I am not able to modify the features file even when I'm
root. I get the following error:

cat: features: Operation not permitted

Good morning Shane,

Can you verify what Linux kernel you are using? See the bottom section

Hello,

I'm trying to configure UHD to work with DPDK and my Intel X550T NIC.
When running the benchmark_rate UHD example, the x310 drops packets and
gives sequence errors even at lower sample rates. Below is an example of
the output from the script. Have I configured something incorrectly?
