Cannot configure tc qdisc TAPRIO on LS1021ATSN

[SH8Lee]

Hello!

I am currently using LS1021ATSN-PA board, and I am using the Real-time Edge Software V2.4.

And I tried a command for configuring the tc qdisc taprio on the interface eth0 of the board.

But when I tried a command below,

tc qdisc add dev eth1 parent root taprio \
num_tc 8 \
map 0 1 2 3 4 5 6 7 \
queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \
base-time 0 \
sched-entry S 80 50000 \
sched-entry S 40 50000 \
sched-entry S 3f 300000 \
flags 2

it prints out an error "RTNETLINK answers: Operation not supported".

Can I know the reason why it doesn't work, and how I can fix the problem?

Thank you, all!

Dear NXP team,

The current issue is that the eth3, eth4, and eth5 interfaces either do not exist or are not being recognized.

Additionally, there are no related messages about these network drivers appearing during the booting process.

Could you please check the network drivers and configurations?

Would you please address your current problem in a new thread?

[KOOBK]

OK, I made a new thread.

[yipingwang]

Got it, thanks.

[yipingwang]

First of all,  it is need to be clear about the ls1021atsn hardware structure. As below. See attached picture 1. LS1021 internal link to the SJA1105. Ethx shows in Linux are the ports eth0/eth1 which links to ls1021. It only supports 1 RX ring and 1 TX ring per CPU. It is not support the TSN function. We called theses ports are the ethernet port as end station.

[SH8Lee]

Thank you for your reply. Then I used the interface eth2, connected to a host. And I configured an IP address using ifconfig tool to the eth2 port, but I even couldn't ping to the host connected to the port. It printed out "Destination host unreachable". How can I fix this? I can't use the port eth2 for networking now. 

[yipingwang]

eth2 is the port connecting to SJA1105, this port only has internal connection, no external connection, the user cannot use it.

[SH8Lee]

I am not clear about your "internal connection only". The LS1021ATSN-PA switch has 6 physical ports. And I think the first 2 ports are normal ethernet ports, and the others are not But, because it is a networking device, I think an user have to be able to use all of the ports, and I want to use all of them, as well.

I wonder how I can do some TSN demonstrations by connecting some hosts to LS1021ATSN-PA switch. If I am right, you are saying that I can't use the other 4 ports for networking, and the 2 ports are for normal ethernet only, not for TSN.

If there is a way that I can do some networking with the other 4 ports, please tell me. In the picture below from the LS1021ATSN part of the Real-time Edge Software UG, it is demonstrated that the 4 ports other than normal ethernet ports, which are "SWP2 ~ SWP 5" from the picture, can be connected to external hosts and communicate.

So, please tell me how I can do this. 

[yipingwang]

You can use swp2-swp5 to implement TSN networking features, use eth0 and eth1 to do normal networking application.

eth2 connects to sja1105 switch, there is no external PHY connecting to eth2, so it cannot be connected to the external networking.

[SH8Lee]

But there are no interfaces named "SWX" for Real-Time Edge Software v2.4 which I am using. For using those interfaces, do I have to use the OpenIL?

Also, is it possible to use the interfaces in the same way as normal ethernet ports as eth0 and eth1 with which I can do some external networking? 

[yipingwang]

Can you get similar result as the following?

Thank you for your detailed reply. Let me try.

By the way are you using the Real-time Edge Software for LS1021ATSN?

[yipingwang]

Yes, please provide Linux Kernel booting up log if the problem persists.
