Hi, We are running DPDK v.19.11.14 on Ubuntu 22.04 LTS. Our goal is to use DPDK to accelerate UDP communication on a Broadcom 57504 network controller.
I have some problems with hugepages and binding of ports and would be grateful for some help please. 1) Firstly, regarding hugepages, our kernel cmdline includes: default_hugepagesz=1G hugepagesz=1G hugepages=25 hugepagesz=2M hugepages=1024 After reboot I see: $ cat /proc/meminfo | grep Hugepages Hugepagesize: 1048576 kB This is no mention of 2MB pages. Is that expected? I call rte_eal_init() with parameter: -m 4000 but see: EAL: 1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size Is that a problem? 2) Secondly, I use dpdk-devbind.py to bind the first device of the 57504 controller to DPDK. dpdk-devbind.py reports: Network devices using DPDK-compatible driver ============================================ 0000:43:00.0 'BCM57504 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb/200Gb Ethernet 1751' drv=igb_uio unused=bnxt_en,vfio-pci but when our application calls rte_eth_dev_count_avail() the return value is 0 and so the application reports: ERROR: EXIT_FAILURE : No DPDK ports found - have you run the DPDK setup script? Any idea why the bound port is not found? 3) Finally, our setup script inserts modules igb_uio.ko and rte_kni.ko. Is this adequate for the Broadcom BCM57504? Best regards David
