[LX2160A] SEC return error when run dpdk application

Jeffrey_Lai — Fri, 03 Dec 2021 03:23:59 GMT

Hi NXP,

We have an issue when run our dpdk application on LX2160A.

After run our dpak application after few hours, we get "SEC returned Error - 400000f1" message.

We try to trace dpdk source and find out if increase dpaa2_dpcp_ctxt struct hfn_threshold value, the issue has been postponed.

Do you get any similar issues and how to solve it ?

Could you tell us hfn_threshold is used for ?

Thank you,

Jeffrey Lai

Please refer to app/test/test_cryptodev.c in DPDK source code, there are some unite test cases containing the section how to use Scatter Gather buffers which are supported in DPAA_SEC driver.

Would you please check whether you used Scatter Gather buffers similar as this test case.
