fmc policer core pool

[ysack]

I'm using SDK 2.0 fmc on T4240RDB board. 

When I use policer as shown below, I see that all traffic passes through a single CPU core. How can I prevent this situation?

<policer name="policer2">

<algorithm>rfc2698</algorithm>

<color_mode>color_blind</color_mode>

<CIR>12000</CIR>

<EIR>34000</EIR>

<CBS>56000</CBS>

<EBS>78000</EBS>

<unit>packet</unit>

<action condition="on-red" type="drop"/>

Please refer to the following explanation.

This is because in DPAA1, each Ethernet interface uses one pool channel across all software portals and also one dedicated channel for each CPU. In Linux Kernel, PCD Frame queues use dedicated channels. You could refer to the section "5. Dedicated and Pool Channels Usage in Linux Kernel" in https://community.nxp.com/docs/DOC-329916 for details.

In the multiple flows scenario, after executing FMC policy, one flow will bind to one core.

Thank you very much for your reply. When I clicked on the link you gave, I saw the qman_driver.c file.
Can you help me on how to use this file?
