LS1088ARDB - reduced bandwidth connection

reza_m — Thu, 13 Aug 2020 22:03:38 GMT

I have been running OpenWRT on the LS1088ARDB. I first tested a 1Gbps internet service plan to make sure the ports were working as specification and it worked using a v17.01.7 build. I then upgraded to v19.03 to get mwan3 support and now the maximum bandwidth i can get is about 70-100 Mbps. I have tried going back to the original image but my bandwidth still seems to be capped. What could the issue be?

Please use NXP latest released OpenWrt OpenWrt-19.04

$ git clone https://source.codeaurora.org/external/qoriq/qoriq-components/openwrt

$ git checkout OpenWrt-19.04

In addition, please disable CONFIG_NETFILTER and CONFIG_CPU_FREQ in Linux kernel.

I used the NXP openwrt release with those configurations set and my connection is still capped at 70Mbps. I have attached my .config file.

I tried using the configuration settings and the build you suggested and my issue persists.

Would you please provide your testing console log?

What tool did you use to measure the maximum bandwidth? Did you use iperf?

Did you build images with the following commands?

* make menuconfig

* make

Final firmware/image

Path: bin/targets/layerscape/<subtarget>/
Firmware for flash: openwrt-layerscape-<subtarget>-<device>-<rootfs>-firmware.bin
Image for SD card: openwrt-layerscape-<subtarget>-<device>-<rootfs>-sdcard.img

I used http://www.dslreports.com/speedtest to measure the bandwidth

I built the image with:

make menuconfig, to choose the target and device

make -j1, to build the image

Could you send me the firmware image you used to test?

Please download the firmware image from openwrt-layerscape-armv8_64b-ls1088ardb-ubifs-firmware.bin - Google Drive

I am still not getting line rate using your image. How did you test if you were getting the full bandwidth.Could you also send me the config file you used to create this image.

Hello Reza Mohammadi,

Please refer to the attached Kernel configuration file, please put it in openwrt/build_dir/target-aarch64_generic_musl/linux-layerscape_armv8_64b/linux-4.14.108 and rebuild image.

Thanks,

Yiping

This config did work either. Are you sure you can get 1Gbps through all the ports using this configuration? How did you set up the network interfaces?

Would you please provide your console log to use “speedtest" tool?

I have attached the log and speed test

Please refer to the following comment from the testing team.

Prepare the environment for networking performance testing:

the nefilter can’t be disabled in compilation .You should disable it manually on board.

root@OpenWrt:/#/etc/init.d/netserver disable

root@OpenWrt:/#/etc/init.d/netserver stop

root@OpenWrt:/#/etc/init.d/dnsmasq disable

root@OpenWrt:/#/etc/init.d/dnsmasq stop

root@OpenWrt:/#/etc/init.d/firewall disable

root@OpenWrt:/#/etc/init.d/firewall stop

root@OpenWrt:/#uci commit && service network restart

remove the related module of netfilter in /lib/module/<kernel version>

mkdir -p /lib/module/`uname -r`/ netfiter_back/

mv nf_* netfiter_back/

mv ip_tables.ko ip6_tables.ko ip6table_filter.ko iptable_filter.ko x_tables.ko netfiter_back/

reboot -f

My issue still persists, what else can I try to solve it?

Please try the latest OpenWrt release, I uploaded it in the following link.

https://drive.google.com/file/d/1uxTNZzrc6Fu-wjaEL5arYe_QjSRnOp-Q/view?usp=sharing

NXP will release a new version OpenWrt on September 25th.

Why would I need to disable netfilters? my firewall and mwan3 setup require those modules. Does this imply I cannot run my setup at line rate?

As noted:

https://www.nxp.com/docs/en/supporting-information/DN-Silicon-bring-up-QorIQ-LS1-Processor.pdf

The LS1088A is targeted for use in industrial firewall applications - are there any reference designs or images to support operation at line rates? Is this implemented within the NXP OpenWRT image?

Please refer to the image built from the latest OpenWrt release(on September 25th).

I have tried building an image with the builder you have sent and I have tried the updated OpenWRT repo. Neither solution is working, what else can I try? Is there a hard reset I could trigger to wipe the flash drives?
