Ibv_device_open fails "No space left on device"

I have issues opening the mlx5_3 device in BF2.
Errno: “No space left on device”
I’m activating dpdk with “-a auxiliary:mlx5_core.sf.2,sft_en=1”
What can cause such an issue?

Looks like you use SFT lib mentioned on DPDK summit right?

This libs should not merge on dpdk mainline so far.

You need run “$ devlink dev show” see if sf device “auxiliary/mlx5_core.sf.2” exist,
And if it configure “devlink port show”,

then if add to OVS “ovs-vsctl show”

If not, try setup and configure SF,
