Hi
Is it possible to add SF on host side with bluefield-2 DPU in ECPF mode?
I have following bluefield-2 smartnic:
vvmiheev@rnd2:~$ lspci | grep 4b:
4b:00.0 Ethernet controller: Mellanox Technologies MT42822 BlueField-2 integrated ConnectX-6 Dx network controller (rev 01)
4b:00.1 Ethernet controller: Mellanox Technologies MT42822 BlueField-2 integrated ConnectX-6 Dx network controller (rev 01)
4b:00.2 Non-Volatile memory controller: Mellanox Technologies NVMe SNAP Controller
4b:00.3 DMA controller: Mellanox Technologies MT42822 BlueField-2 SoC Management Interface (rev 01)
When I try to switch PF on host side to switchdev mode I get error: kernel answers: Operation not supported
vvmiheev@rnd2:~$ sudo devlink dev eswitch set pci/0000:4b:00.0 mode switchdev
kernel answers: Operation not supported
If I try to add SF on host side without switching to switchdev mode I also get error:
vvmiheev@rnd2:~$ sudo devlink port add pci/0000:4b:00.0 flavour pcisf pfnum 0 sfnum 88
Error: mlx5_core: Port add is only supported in eswitch switchdev mode or SF ports are disabled.
kernel answers: Operation not supported
I can add SF on arm side with both representor port and main port on arm side.
I also tried to add SF with main port on host side and representor port on arm side issuing commands on arm and specifying controller number 1
vvmiheev@SC-WS-00753:~$ sudo devlink port add pci/0000:03:00.0 flavour pcisf pfnum 0 sfnum 32 controller 1
kernel answers: No space left on device
How to create SF with main port on host side and representor port on arm side?
