To refresh the info here I want to say that using this version @qosmio branch with the qcom_rpm regulator added by @Ansuel
root@R7800:~# uname -a
Linux R7800 5.15.69 #0 SMP Fri Sep 30 06:44:45 2022 armv7l GNU/Linux
I don't have a reboot for more than 8 days. Maybe we are on the right track.
i'm not sure if this is the place to put this
I tried out @ansuel 's latest 5.15 ipq806x experimentation branch on a Linksys EA8500
Two problems :
eth0 is broken (but eth1 is fine) I thought about trying something after looking here https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=f93267bccff672e59ec0d0cf262e6574b00cc3e0 but dont have a lot of time to mess around
I ran iperf3 a couple of times with a realtek r8153 usb adapter connected to the ea8500 and it cut out after a few runs ( --reverse) and this appears to work reliably with the standard 5.10 build. So usb isn't as reliable at least with network adapters.
Obviously it was too early to make any assumptions about the stability. Reboot just happened with three files in pstore. To not confuse anyone this is with @qosmio 5.15-qsdk11-new-krait-cc build with the qcom_rpm regulator added by @Ansuel.

I am able to avoid an NSS core dump in qca-nss-tunipip6.
NSS.AK.K.CS-1-R firmware requires QSDK11.2 qca-nss-drv and qca-nss-tunipip6 drivers.
I made a reversion patch for tunipip6 only.
and I made some patches for openwrt-ipq806.
I will create PR, please review them.
Master just bumped up to 5.15.
I'm getting this error with 5.15. Any suggestions for what the correct nomenclature is for this line in the .dts patch.

In order for me to not have to read 3000+ messages, may i ask a few simple questions?
-the ipq8074 has, aside from its two cortex cores, two nss cores. why are they not enabled by default in the standard openwrt built? Does this has to with binary blobs needed to get them to run, or is this duo to other reasons?
-does a c2600 owner has anything to gain from enabling the nss cores when he uses his c2600 purely as an accesspoint?
-are the nss cores powerfull enough to make a big difference in througput?
I hope im not being to blunt, but 3000+ posts i just too much of a read.
Unfortunately the R7800, that I use to test the 5.15-qsdk11-new-krait-cc build, has just crashed completely.
It didn't reboot and could not recover by itself. I had to completely cut the power to restart it.
It was not possible to make any connection to it. Web server, SSH, none of them worked.
@ACwifidude I hope you keep the current working master branch with 5.10 so we can at least have a working and I really hope very stable version.
I've switched to performance governor to check if it will crash again.
ipq806x NSS activation requires additional blobs as you eluded to. This community build has the additional patches for OpenWrt to be able to run the publicly available qca blobs.
NSS partially offloads wireless and allows for more performance. If you have fast enough internet it might be worth it. I use it on two r7800 access points.

@sppmaster unfortunately master has moved on to 5.15. 22.03 is still 5.10. If we can get 5.15 working with all the latest commits I’ll start building on 5.15. 
@ACwifidude I need several kmods for LTE modems and other purposes. Are there any technical barriers to make nss builds with CONFIG_ALL_KMODS=y?
There was an unrelated kmod several months back that was not being nice during the build process so I removed the config. It probably has been fixed by now so I can give the config with all kmods another try. I’ll probably try to build again this weekend. If you need it sooner than that you can build based off the steps in post #2 and include your needed packages.
you need to add the supply binding to the smb208 dtsi in 5.15
device already use the smb208 dtsi so you just need to fix that
After a while of being busy with work i return with my EA7500V1.
Unfortunately now both stable and master have random reboots, even with performance gov and playing with various parameters, removing services etc.
Also the memory like before seems to hit a hard wall at 143 MB used (trying to use more by placing stuff in /tmp simply results in oom triggering). Maybe it's the nss driver being loaded in memory? Still doesn't answer why stock owrt has less than a quarter of that usage.
What can there be tried? Do i wait for 5.15? Does the router simply not have enough RAM for the nss stuff, even thoguh 256 is considered "quite a lot" and oom doesn't trigger when it reboots?
Is it only wireless that gets offloaded? Is there benefit for me running openwrt strictly as a router without wifi with multiple openvpn client connections.
I've created some patches on @qosmio's branch and created a PR.
These can apply @ACwifidude's master branch.
I built it and started testing pppoe, ds-lite, l2tpv2 and irqbalance.
I managed to build snapshot with all necessary kmods, except gre (there were build errors with CONFIG_PACKAGE_luci-proto-gre=y option). Really, wireless performance increased by 15-20% with nss.
There is more offloading to NSS cores; your Internet connection gets offloaded too. So running your router strictly as a router without WiFi will still be interesting. SQM offloading is also possible but only with fq_codel, not CAKE. It really depends on your ISP if you need SQM at all if you’ve got a fiber connection for instance.
Now on the OpenVPN part in combination with offloading, that’s not implemented (yet) I believe. So it depends on what you actually need in terms of throughput. Just give it a shot, remember to disable packet-steering, irqbalance, software offloading (in firewall settings) and either choose the performance governor or clamp your cpu frequency of both CPU’s to a fixed setting
Thanks for the detailed reply! I have my main r7800 with hnymans builds I've used forever and will be installing acwifidudes nss build on a spare r7800 as a clean flash to try out.
I have a fibre 500/500 PPPoE connection btw.
I used hnymans build too before I switched from a 300/30 Mbit/s DOCSIS to a 500/500 Mbit/s fiber connection with PPPoE. The R7800 (or any ipq806x device for that matter) can't handle internet connections much faster than 400Mbit/s if you're not doing too much else on your router. Both CPU's will just max out to 100%. The R7800 is capable of about 940Mbit/s though with the factory firmware from Netgear. A NSS enabled build (like this one) will get you the possibilities of OpenWRT at just about the same speed as the factory image. It's pretty stable too, when you follow the best practices regarding irqbalance, packet steering, software offloading and fixating the CPU frequency. And as you can see by the number of replies in this topic; it's pretty popular too
The recommended configuration in the first few posts says
Irqbalance enabled, packet steering disabled
Is that out of date?
Yep. Currently it's out of date.
Irqbalance isn't even included in latest @ACwifidude master builds.
