DPAA2 DPDK RTE FLOW

[dehml]

Hello,

I'm trying to create DPDK RTE FLOW on a DPAA2 SolidRun LX2160A Clearfog CX without success.
Is it normal that it doesn't work ?
What could be done to make it works ?

I'm quite newbie with NXP DPAA2 and NXP in general, so can you please explain your technical words.

Thanks.

testpmd> flow create 0 ingress pattern eth / ipv4 / end actions rss queues 0 1 end types ip ipv4 end / end
DPAA2_NET: Add entry(0) to table(0) failed
DPAA2_NET: Create flow failed (-22)
port_flow_complain(): Caught PMD error type 1 (cause unspecified): cause: 0xfffff340a300, unknown: Operation not permitted

Check how the DPNI behind your DPDK port was created. From the Linux shell on the board:

restool dprc show dprc.1 --resources          # find the dpni.X your DPDK port uses

restool dpni info dpni.X                      # look at the "options" line and "num_queues"

If options shows DPNI_OPT_NO_FS , or does not show DPNI_OPT_HAS_KEY_MASKING , that's your problem.

Recreate the DPNI with the right options. Either edit dynamic_dpl.sh (or the environment it reads — on NXP LSDK it is typically the DPNI_OPTIONS variable) so the create call looks like this :

restool dpni create \

    --options=DPNI_OPT_HAS_KEY_MASKING \

    --num-queues=2 \

    --num-tcs=1 \

    --container=dprc.2

Key points:

• Do not include DPNI_OPT_NO_FS .

• Do include DPNI_OPT_HAS_KEY_MASKING .

• Set --num-queues to at least the number of queues your RSS action references (you asked for queues 0 and 1, so ≥ 2).

Then attach that DPNI to the DPDK container ( restool dprc assign … ) and rerun testpmd.

If you use a static DPL file , add the same to the dpni@X node :

 dpni@1 {

  options = "DPNI_OPT_HAS_KEY_MASKING";

    num_queues = <2>;

    ...

};

and reflash the DPL via fsl_mc apply dpl … in U‑Boot.

Sanity‑check with a simpler rule first. Before RSS, confirm plain steering works:

 testpmd> flow create 0 ingress pattern eth / ipv4 src is 10.0.0.1 / end \

                     actions queue index 1 / end

If this passes but the RSS variant still fails, the remaining issue is queue count / distribution config, not the DPNI options.

BTW. what kind of BSP or SDK is used? Any resource from official websit?
