dpaa2_net: dpni disable failed (-110) DPAA2, DPDK

nic30 — Wed, 01 Aug 2018 12:10:31 GMT

Hello,

I am using DPDK on LS2088ardb board.

I have allocated 1 DPNI and connected it to 1 DPMAC.1 (SPF+).

When I start DPDK testpmd application it works and can be closed only if incomming trafic is ~100 pkt/s.

If I send packets on wirespeed from another PC testpmd application can not be closed (even after traffic generator is stopped)

There is only one error:

Shutting down port 0...
Stopping ports...
dpaa2_net: dpni disable failed (-110)
dpaa2_net: Failure (ret -110) in disabling dpni 0 dev
Done
Closing ports...
dpaa2_net: Failure cleaning dpni device: err=-110
Done

If I run testpmd application it can not receive any packets.

Output from /dev/fsl_mc_console

[E:36f3b2a5ec, ifp_mng_cmd_enqueue:1708, CTLU] Busy: No available Management command descriptor

[E:36fb871426, qbman_rec_isr:387, QBMAN] [FQ#7]: 12036

...

What does error -110 means? Is there any document about /dev/fsl_mc_console ?

Hello nic nic,

This is a known issue in our internal system, the development team is working on it now.

When killing the application while the traffic is running.

Application kill with print:

dpaa2_net: dpni disable failed (-110)
dpaa2_net: Failure (ret -110) in disabling dpni 2 dev
dpaa2_net: Failure cleaning dpni device: err=-110

After this - it is not possible to use the system for dpdk without re-starting the board.

Will fix this issue in the coming release.

Have a great day,
TIC
