Hi all,
I am trying to enable DPDK with X410 and found an issue when using
“use_dpdk=1”. I am on Ubuntu 22.04, the latest UHD 4.4.0 (commit:
4a77791cf5f7cedc842762be8b2b6775073d8c95) and DPDK 21.11.4.
When the X410 is connect to the interface without DPDK, I can find it via
uhd_usrp_probe and run benchmark_rate without issue. After binding the NIC to
DPDK, the X410 can no longer be found when using DPDK. Anyone know why it’s
disappearing?
Output of find devices before DPDK is enabled:
