Hi,Yiping:About 3 hours after running the lpm-ipfwd demo,the ethernet port which is of share-mac cannot work

shanfeifei · ‎01-17-2016

Hi,Yiping.recently I met a problem.

My board is P4080ds,I want to test the lpm-ipfwd demo.I configured the fm1-gb2 and fm2-gb3 as share-mac, and when I ran the lpm-ipfwd demo,at the beginning of about 3 hours,it worked well.But after 3 hours,promblem happened.The fm2-gb3 ping time out,but the fm1-gb2 ping well.I typed "ps -A | grep lpm_ipfwd_app",it still there:" 1655 ttyS0 lpm_ipfwd_app". It looks like that lpm_ipfwd_app was still working,but fm2-gb3 cannot work,so how could I solve the problem?

appendix:

the command is :lpm_ipfwd_app 1..7 -c usdpaa_config_p4_serdes_0xe.xml -p usdpaa_policy_hash_ipv4_arp_coarse_classify.xml -d 0x10000000 -b 1600:1600:1600 -n.

Hello Feifei,

In your original description, you pass the serdes 0xe configuration file to fmc, it seems that this is not coincident with your current target configuration.

Would you please also provide u-boot and Kernel log? It's better to include steps to setup lpm_ipfwd_app.

Have a great day,
Yiping

Hello Feifei,

Would you please provide the console log for running lpm_ipfwd_app? Probably the system provide some error information for debugging.

Thanks,

Yiping

shanfeifei · ‎01-18-2016

Hi,Yiping,

there was no error information in the console log.

Yestoday,I did an experiment :I unplugged the Ethernet cable which connected to Internet,with only a local area network left.The lpm-ipfwd demo ran well all the time,and the fm1-gb2 and fm2-gb3 ping well.

But about 3 hours after I using the Ethernet cable to connect the Internet,promblem happened，The fm2-gb3 ping time out,but the fm1-gb2 ping well.I typed "ps -A | grep lpm_ipfwd_app",it still there:" 1655 ttyS0 lpm_ipfwd_app". It looks like that lpm_ipfwd_app was still working,but fm2-gb3 cannot work.（fm1-gb2 acess to LAN and fm2-gb3 acess to Internet）

I typed the following command:

root@p4080ds:~# ifconfig fm2-gb3

fm2-gb3 Link encap:Ethernet HWaddr 00:0c:bd:00:d0:95

inet addr:192.168.2.221 Bcast:192.168.2.255 Mask:255.255.255.0

RX bytes:146255111 (139.4 MiB) TX bytes:3570626 (3.4 MiB)

Memory:fe5e6000-fe5e6fff

Then I referred to the document Data Path Acceleration Architecture Debug(FTF-NET-F0148),and I typed some command as follows to check that if fm2-gb3 could receive frames:

root@p4080ds:~# ls /sys/devices/ffe000000.soc/ffe500000.fman/ffe58b000.port/statistics/*

fm1-port-rx3 counter: 1800718

fm1-port-rx3 counter: 0

fm1-port-rx3 counter: 463133

It shows that the count of port_rx_out_of_buffers_discard is 463133,and the counts of port_rx_out_of_buffers_discard is always incremented.

The document shows that the defination of port_rx_out_of_buffers_discard is that

Number of received frames that were discarded due to lack of external buffers.

Counts the number of frames on the Rx port that were not able to enter the receive queue, since buffer allocation has failed.

It looks like that once I used the Ethernet cable to connect the Internet, problem happened,and the buffers is not enough,so how could I solve the problem?

yipingwang · ‎01-19-2016

Hello Feifei,

In P4080DS default shared MAC device tree p4080ds-usdpaa-shared-interfaces.dts, fm2-10g is defined as the shared MAC interface between USDPAA and Linux.

In your description, you mentioned that you configured fm1-gb2 and fm2-gb3 as shared MAC interfaces between USDPAA and Linux. How do you modify the shared MAC device tree to define these two shared MAC interfaces? How do you define the buffer pools and QMAN tx and rx frame queues in your modified dts file?

Have a great day,
Yiping

Hello Feifei,

Please modify ethernet@9 definition to use other buffer pool rather than &bp17, because buffer pool &bp17 has already been assigned to ethernet@8.

Hi,Yiping,thank you for your reply!

Actually in RCW the ethernet@9 is disabled,and I only enable 3 ethernet ports:ethernet@2 ethernet@7 ethernet@8,so need I to change other buffer pool for ethernet@9?

shanfeifei · ‎01-19-2016

Hi,Yiping,I have found the problem.In lpm-ipfwd demo,I Modified the code which didnt free the memory,so the buffer pool was always decreasing.

So thank you very much for your guidance!

shanfeifei · ‎01-19-2016

Hi,Yiping,thank you for your reply!

My original description shows that the command is :lpm_ipfwd_app 1..7 -c usdpaa_config_p4_serdes_0xe.xml -p usdpaa_policy_hash_ipv4_arp_coarse_classify.xml -d 0x10000000 -b 1600:1600:1600 -n.

I rewrote a configuration file on the basis of the file usdpaa_config_p4_serdes_0xe.xml,but the contents inside has nothing to do with the usdpaa_config_p4_serdes_0xe.xml.

The contents inside the usdpaa_config_p4_serdes_0xe.xml is that:

</engine>

</engine>

</config>

Welcome to FEC! p4080ds Saturday, 16 January 2016 09:45:30

Today the problem happened again,and I checked that the buffer pool for fm2-gb3 which was connected to Internet has no buffers:

# cat /sys/devices/ffe000000.soc/ffe31a000.bman/pool_count/17

0

But the buffer pool for fm1-gb2 which was not connected to Internet has many buffers

# cat /sys/devices/ffe000000.soc/ffe31a000.bman/pool_count/16

1600

So how do I solve the problem? Thank you !
