Does any one noticed that recent trunk has IRQ VPE enabled but moving ethernet IRQ (72 / 73) to second core kills network ?
kernel 5.4 + DFS + VPE patch didn't had that issues as I'm still using it on "production" FB7412
Indeed i noticed the same thing.. I am able to move the ath9k interrupts to the second core. But moving the dsl or erhernet interrupt hangs my wr9980.
Hi, I have Astoria networks VGV7519 (VRX288 V1.2) running latest stable OpenWRT v21.02.3.
My internet uplink is pppoe ethernet 100mbps (I don't use dsl/telephony)
What patches/settings would you advice to improve performance of this unit? I already enabled "Software flow offloading", but would like to go a bit further.

Please use 22.03.0-rc1 or trunk It contains major improvements for lantiq platform . And there will be more in stable 22.03.0 branch in next few months .
I tried both 22.03.0-rc1 and trunk but there is still 1 core shown in /proc/cpuinfo and no SMP support. So do I still need to compile myself and apply some patches?
lantiq devices with FXS (analogue phone-) ports reserve one CPU core as voice core (running a special voice firmware and reserving 2 MB of the main RAM). If you don't need that and want to re-use the second core as CPU core, you will have to adapt the cmdline in your device's dts and rebuild OpenWrt (from source).
This is the expected behaviour and not a bug.
What do i need to edit in the .dts to enable the second core on ARV7519RW22?
That should be &vmmc
declaration but since i cannot see it vr9_arcadyan_arv7519rw22.dts so I assume You will need upgrade to OpenWRT 22.03 or master cause old builds doesn't have SMP
I just installed 22.03.2 stable on a Fritzbox 7412. SMP seems to be enabled but I still only get ~25 Mb/s via VDSL. I assume the neccessary patches to improve performance are not (yet) included in this version? Can somebody give me a quick sum up of which patches to apply?
Can you post the output of:
ubus call dsl metrics
and a screenshoot of all the information shown by the go-dsl tool (there is a download link on that page if you do not want to build it yourself)?
We can take it from there

go-dsl somehow doesn't work for me, it exits with status 127.
Not sure, but likely not configured correctly, @janh?
Maybe try the following from the command line:
./dsl -d lantiq_ssh -o Command="dsl_cpe_pipe.sh" -u root openwrt.lan # OpenWrt
replace the openwrt.lan
with your FB's IP address, if that works I am confident the GUI version can also be configured corrctly somehow.
That is ~63.7/12.7 Mbps data rate so your 25Mbps result does not seem to come from the actual VDSL link. Could you post a speedtest from your link?
If I might ask, which ISP and what speed where you offered? This looks a bit like Deutsche Telekom's nominal 50/10 plan, which IIRC provisions something around 63/12 as gross rates.
That actually worked:

You guessed right, this is a 50/10 plan from 1&1 (via DTAG). I get quite rock solid 53 Mb/s down, 11 Mb/s up with a stock firmware 7362. 7412 with OpenWRT 22.03.2 only reaches between 20 and 30 Mb/s down.
OK, in theory the same credentials should also work with the GUI version, it would be nice to see the spektra...
But I doubt that the DSL link is your problem. Whem you run a speedtest could you please:
Matybe this will help figuring out where the problem sits.
Exit status 127 means that the command was not found. It should work if you specify the command dsl_cpe_pipe.sh
in the advanced options.
OK, using the LAN connection, I am actually able to get the full line speed. First CPU core is at 100%:
With a wifi connection, I only get around 28 Mb/s. The wifi connection to the router itself is shown with 130 Mb/s. CPU load is somewhat lower though:
Well xrx200 generation really is hard pressed doing things concurrently. When I tried my BT HomeHub5A as All-in-one dsl-router I also noted that even at 50/10 (back then the sync was ~50/10, not 63/12 ;)) the router was reaching its limits when dsl and WiFi were used at the same time. I think it might be possible to optimize things a bit, but really under OpenWrt the xrx200 devices are better used as bridged modems only. In my case this works with a nominal 100/40 link (sync 116.7/37.0 Mbps) with the sme HH5A that struggled as a wifi dsl router at 50/10.
OK, not a deal breaker for me. In daily use it works fine for me, most of the time I'm connected to a beefier AP anyway, which gives me full wirespeed over the LAN connected 7412 after all. Not bad for a device from the junk box that I got for free. Pretty happy that I was able to eliminate the last proprietary alien from my network now. Thanks to everybody who helped to improve the Lantiq platform.
