[LS1046A][DPAA1] How to check DPAA1 is working?

alance · ‎12-01-2020

Hi

We'd like to set Ethernet port cross-connect using FMC as this thread. However, failed to get it work. There is no traffic seen on another port. Are there any ways to check DPAA PCD status? Thanks.

Here are my settings.

ethernet@8 {
compatible = "fsl,dpa-ethernet";
fsl,qman-frame-queues-rx = <0x5c 1 0x5d 1 0x50 1>;

fsl,fman-mac = <&enet7>;
dma-coherent;
};

There is limitation in Linux Kernel to handle PCD distribution queues as the above method, we could implement this purpose in USDPAA through this PCD configuration.

Hello, by this example i'm trying to forward something from one mac to another, and not understand if kernel crashes, is it possible to forward some any trafic by fman? or another question if NO so for what FMAN stands for if can't do forwarding?

Please check whether it could work when configure Rx queue in the PCD policy file.

policy_ipv4.xml

In addition, please modify policy file based on /etc/fmc/config/private/ls1046ardb/RR_FFSSPPPH_1133_5559/policy_ipv4.xml.

Please try whether it could work normally when executing

fmc -c /etc/fmc/config/private/ls1046ardb/RR_FFSSPPPH_1133_5559/config.xml -p /etc/fmc/config/private/ls1046ardb/RR_FFSSPPPH_1133_5559/policy_ipv4.xml -a

Hi YiPing

Had tried setting Rx and Tx error queues on PCD. Both work fine and I can check the ifconfig counters. However, kernel crashes when sending a packet to PCD with the Tx queue. Can we set TX FQID on the PCD distribution queue? Or any settings we need to set beforehand?
