Hello,
I am learning DPDK.
I am using the following network cards that support dpdk.
https://www.broadcom.com/products/ethernet-connectivity/network-adapters/100gb-nic-ocp/p2100g
I am seeing rte_eth_dev_count_avail is failing. code is as follows:
====================================
nb_ports = rte_eth_dev_count_avail();
if( nb_ports < 2 || ( nb_ports & 1 ) )
rte_exit( EXIT_FAILURE, "Error: %u number of ports must be
even\n", nb_ports );
====================================
I have one card and just because it is for learning purposes, I have looped
back both the slots of the same cards so that I can send on one slot and
receive on another slot.
Can someone please help me how to fix the issue.
Device Driver is bnxt_en
Platform is Ubuntu 22.04
Please let me know if any more information is required.
Thanks & Regards
--
Lokesh Chakka.

LED is also glowing. Indeed, DPDK provides a userspace driver for some NetXtreme nics (which is net/bnxt). This userspace driver does not rely on the bnxt Linux kernel driver. IOW, this card being detecting and working with the Linux kernel does not automatically mean that this nic can work with DPDK. We need more info on your nic, first. Can you share the pci id of this nic (like running lspci -n -s $pci_address)? It should be a 14e4:XXXX. Then you can check this XXXX against what your dpdk application supports. If it is a statically linked application, you can run: $ dpdk-pmdinfo.py /path/to/your/application Else, if your application is dynamically linked against DPDK driver, you can run this command against the net/bnxt driver .so.22 (for 21.11 and later releases): $ dpdk-pmdinfo.py /path/to/your/dpdk/drivers/librte_net_bnxt.so.22 You should get a list of supported NetXtreme nics, like: [snipped some other drivers compiled in my application] PMD NAME: net_bnxt PMD HW SUPPORT: Broadcom Inc. and subsidiaries (14e4) : BCM5745X NetXtreme-E RDMA Virtual Function (1606) (All Subdevices) Broadcom Inc. and subsidiaries (14e4) : BCM5745X NetXtreme-E Ethernet Virtual Function (1609) (All Subdevices) Broadcom Inc. and subsidiaries (14e4) : BCM57454 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb Ethernet (1614) (All Subdevices) Broadcom Inc. and subsidiaries (14e4) : NetXtreme-E RDMA Virtual Function (16c1) (All Subdevices) Broadcom Inc. and subsidiaries (14e4) : NetXtreme-C Ethernet Virtual Function (16cb) (All Subdevices) [snipped the rest] I hope you can find a (XXXX) corresponding to your NIC. -- David Marchand ^ permalink raw reply [flat|nested] 6+ messages in thread
