Hello,

I've installed dpdk in Ubuntu 23.10 with the command "sudo apt -y install
dpdk*"

added  "nodev /mnt/huge hugetlbfs pagesize=1GB 0 0" in /etc/fstab
added "vm.nr_hugepages=1024" in /etc/sysctl.conf

rebooted the machine and then did devbind using the following command:

sudo modprobe vfio-pci && sudo dpdk-devbind.py --bind=vfio-pci 63:00.0
63:00.1

Huge page info is as follows :
