Enabling DOCA Support in OVS on BlueField DPU

[tuanama]

Hi,

I am trying to enable DOCA support in Open vSwitch (OVS) on a BlueField-2 DPU running Ubuntu 22.04. Currently, OVS shows:

datapath_types      : [doca, netdev, system]
doca_initialized    : false
doca_version        : 3.1.0105

I have attempted to set the datapath with:

ovs-vsctl set Open_vSwitch . datapath_type=doca
systemctl restart openvswitch-switch

and also tried loading the expected kernel modules (mlx5_doca, doca_drv) with modprobe, but they are missing from /lib/modules/5.15.0-1074-bluefield/updates/dkms/. Only mlx5_core.ko and other RDMA modules are present.

My questions:

1. Which package or procedure is required to install the DOCA kernel modules (mlx5_doca.ko and doca_drv.ko) on the DPU?

2. Once installed, are there additional steps needed for doca_initialized in OVS to change to true?

3. Is there a recommended script or installation within the bf-bundle 3.1.0105 to enable DOCA flows in OVS?

Thanks

I follow this step on doc OVS-DOCA

mkdir -p /hugepages

mount -t hugetlbfs hugetlbfs /hugepages

echo 4096 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

systemctl start openvswitch

systemctl start ovs

ovs-vsctl --no-wait set Open_vSwitch . other_config:doca-init=true

ovs-vsctl set Open_vSwitch . other_config:hw-offload=true

systemctl restart ovsdb-server.service

systemctl restart ovs-vswitchd.service

systemctl status ovsdb-server.service ovs-vswitchd.service

ovs-vsctl list Open_vSwitch
