Well, 19.07.1 is performing fine for LAN->DSL WAN vrx200/HH5A with the packet steering scripts and software flow offloading, however due to the ptm and ath10k pinning to CPU0, the WLAN0->DSL WAN often tops out ~85 MB/s, only sometimes reaching 100-104 MB/s to tease that it is capable.
I believe manually punt Ath10k away from DSL (ptm_mailbox_isr) will fix this, so I am going to try and test these patches against 19.07.1; Has anyone used these with 18.07.1 for HH5A sucessfully yet to fix 5G WiFi->DSL performance?

I am going to test the patches now with v19.07.1 but I do not use the 5G WiFi so cannot comment on the performance of that one.
I have bad expirience in VDSL -> Wlan using 4.19.65 patches on W8970@achmar16 I'm looking forward to test irq-smp patches with recent 19.07.01

You need to understand that 0904 patch is for Ethernet driver and not for VDSL. I think you need to check your LAN to LAN performance on the router itself. For that use two instances of iperf3 in TCP mode on 127.0.0.1, one would be the server and the other would be the client on the same router. You can also check your CPU load while iperf3 test is happening through htop. I am using the patches 0901 and 0902 with v19.07.1 and the best I am getting is 4mb/s with Samba v2 and 100% CPU load while transferring the files.
One more thing, if you want increased speed then I suggest you change your build environment to v18.06.x and apply the patches. AFAIR I was able to get 10mb/s at some point in v18.06.
Yes I know .... 0904 can be unrelated to low vdsl to wlan performance . There is no problem when client is connected via ethernet with vdsl2 @60Mbit I have

OK testing on current (less than week back) snapshot of openwrt, kernel 5.4 (testing/experimental). For dual VPE IRQ you need just this patch:
0901-add-icu-smp-support.patch
everything else regarding to the dual VPE interrupt driver is in vanilla by now.

Anything I'm doing wrong here? Or is this patch not suited for 4.14.171?
Try this . It may work for you with 4.14 I guess or maybe with v4.19 too.

They work. Thank you. I guess 0903-add-icu1-node-for-smp.patch then isn't need?
I guess it has been merged with the other patches probably.

@pc2005 Are you going to try getting 0901-add-icu-smp-support.patch into Openwrt git?
Also seems like the Openwrt git commit missed (on purpose or otherwise) devicetree reg entries for ar9 and falcon.

I installed the patches and my HomeHub 5A started behaving abnormally. USB started malfunctioning and it would not either mount or read any data. WiFi would not work if I changed the smp_affinity to 2, 1 or 3 was fine. I didnot make any change to USB IRQ though. SO I had to revert back to normal v19.07.2.

I hope I will get it into mainline kernel :-).
There is reg patch for AR9 in your link :-/, are you using 5.4 kernel? There was difference between vanilla kernel and openwrt kernel DTS structure in older kernels. IIRC I was told there were some leftovers which will be deleted, but I don't own these so I relied on kernel mailing list hints.
Do you have logs (dmesg, /proc/interrupts during traffic)? That almost looks like the second VPE doesn't get interrupts at all (but it should) .. and the 0901-add-icu-smp-support.patch is not applied.
No I dont have the logs because I reverted back to un-patched kernel and everything came back normal. Right now I am using v5.4 kernel patches and they work fine. Also I am getting up to 9 MB/s on 2.4GHz and 23 MB/s on 5GHz with all your patches applied.

No, not on the lantiq experimental 5.4 as yet. Was just noting that the devicetree were missing the second reg entries for icu1 on those devices compared to your original patches.
Has 0901-add-icu-smp-support.patch made it into kernel 5.4 yet? If not does anyone have a patched version of this Kernel for using on a BT Homehub 5a, running OpenWrt 21.02.0?

Hello I applied this patch (0901-add-icu-smp-support.patch shared by pc2005 few post ago ) on my BT HomeHub 5A, and few others (pull/3946 , pull/4326 , pull/4339 and pull/4353 , just because I like to break stuff), how can I check if this is really working?
