How can we make the lantiq xrx200 devices faster

For Developers
#245

wan to lan
wan to 5ghz
lan to 5ghz

i tested these but performance is still poor

#246

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

#247

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.

#248

You should use this patch.
0901-add-icu-smp-support.patch

#249

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.

#250

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 .

#251

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?

#252

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.
