TDA4VM: EST est problem with native driver

Matthew

Part Number: TDA4VM

When using Native Driver, the verification of the TAS function using CPSW9G alone is normal. However, if you use the CPSW9G Switch-Mode, whether it is Mac Bridge or Vlan Bridge, the packets cannot send from the designated queue。

Hi,

Can you share the SDK version you are using and scripts/applications you run when you receive the error.

Regards,

hi，

My sdk version is sdk8.5 ,below is my operating environment, where T is a VM product board, VH and VM are the development board:

On the VH board, I ran the following script，

#!/bin/sh
ifconfig eth4 down
ifconfig eth1 down
ifconfig eth2 down
ifconfig eth3 down
ethtool -L eth2 tx 3
ethtool -L eth3 tx 3
sleep 10
ethtool --set-priv-flags eth2 p0-rx-ptype-rrobin off
ethtool --set-priv-flags eth3 p0-rx-ptype-rrobin off

ip link set dev eth2 up
ip link set dev eth3 up
sleep 5
ip link set dev eth2 master br0
ip link set dev eth3 master br0
ip link set dev br0 up

ip link set dev br0 type bridge vlan_filtering 1
bridge vlan add dev br0 vid 402 pvid untagged self
bridge vlan add dev eth2 vid 402 master
bridge vlan add dev eth3 vid 402 master

phc2sys -s clock_realtime -c eth2 -m -O 0 > /dev/null &

sched-entry S 4 400000 \
sched-entry S 2 200000 \
sched-entry S 1 100000 \
flags 2

On the VM board, I ran the following script，

ip link add link eth0 name eth0.402 type vlan id 402
sleep 3

ifconfig eth0.402 192.168.5.111

while true; do ./plget -m rx-lat -f ipgap -n 128 -i eth0.402 -t udp -u 5003 ; done

On the T board， I ran the following script，

ifconfig eth1 192.168.5.90

./plget -i eth1 -m pkt-gen -t udp -u 5003 -a 192.168.5.111 -n 128 -l 80

The picture below is the receiving result，The results show that eth3 realizes the TAS function。

Then I continue to run on the VH as follows script：

tc qdisc add dev eth3 clsact

tc filter add dev eth3 egress protocol ip prio 1 u32 match ip dport 5003 0xffff action skbedit priority 3

When I sends a message on the T board again, the result is as follows

According to my expectations, the larger time interval in the result should be 300us instead of 600us。

Please tell me where there is a problem！

thanks！

Dear Ruiqing,

Please check the script you are using, could you help check not using Vlan and see if it helps.

Other processes are the same as before.

The following is the result of running, it still does not look effective.

Dear Rui qing,

We think this is due to two eth interface and the traffic goes through a longer path.

Dear SiKai，

The board cards are directly connected through the network cable，I think the 600us time above is the interval of 400+200，The phenomenon looks more like flowing filtering are not effective.

If the flow filtration takes effect, I think the time interval will become 300us.

Hi,

The traffic might not be falling into correct queues. This is causing the all the traffic to be sent from queue0 which can explain this behaviour.

To check this, can you share the output of :

ethtool -S eth2
ethtool -S eth3

tc qdisc add dev eth3 clsact

tc filter add dev eth3 egress protocol ip prio 1 u32 match ip dport 5003 0xffff action skbedit priority 3

When I sends a message on the T board again, the result is as follows

In the above case, are you sending packets from VM or VH?
