DPDK ON issue

[houshangaziziaccelleran]

Hello

Based on

ad@bm-super11-intel:~/pure$ sudo dpdk-devbind.py -s

Network devices using kernel driver
===================================

0000:70:00.1 'Ethernet Controller X710 for 10GbE SFP+ 1572' if=ens2f1 drv=i40e unused=vfio-pci 

The server has 64 CPUs:

ad@bm-super11-intel:~/pure$ lscpu
Architecture:            x86_64
  CPU op-mode(s):        32-bit, 64-bit
  Address sizes:         46 bits physical, 57 bits virtual
  Byte Order:            Little Endian
CPU(s):                  64

knowing ens1f1 and ens1f2 are the server interfaces connected to n310, how do I have to configure the following part?

hal:
  eal_args: "--lcores (0-1)@(0-63) -a 0000:43:00.2"

With or without eal_args part, I always get:

The PRACH detector will not meet the performance requirements with the configuration {Format B4, ZCZ 0, SCS 30kHz, Rx ports 1}.
Lower PHY in quad executor mode.

--== srsRAN gNB (commit f3ed07a5a) ==--

Connecting to AMF on 10.55.7.40:38412
Failed to load RF plugin libsrsran_radio_uhd.so: libsrsran_radio_uhd.so: cannot open shared object file: No such file or directory
Factory for radio type uhd not found. Make sure to select a valid type.
srsGNB ERROR: Unable to create radio session.

The issue started when I installed srsRAN with DPDK set to ON.

Please follow every step of the following guide! https://docs.srsran.com/projects/project/en/latest/tutorials/source/dpdk/source/index.html

I would advise to bind the interface manually, and use the following eal_args:

hal:
  eal_args: "--lcores (0-1)@(0-63)"

If the error persists please the provide following info:

• DPDK version
• cmake and make output including the cmake command

@houshangaziziaccelleran any update on this issue?

[houshangaziziaccelleran]

Sorry for the late response @pgawlowicz I am busy with another project. We can close this for now and if I still have the issue, I will open a new one. Is that OK?
