IPQ806x NSS Drivers

Gram · October 28, 2020, 12:28pm

Ramoops is a linux kernel functionality since 2011 and designed for that particular purpose. It just seem it is not widely discussed in the forum.

My hunt for crash logs with the ramoops started after last Thursday router restart during the MS Teams conference call with customer (luckily was not presenting at the time) and my remote syslog server did not capture any related logs.

Basically you need to activate pstore/ramoops in the kernel using kernel_menuconfig or modifying dts file. As I've no knowledge of dts modifications, I modified kernel parameters (make kernel_menuconfig).

Activate pstore with ramoops as backend (File systems --> Miscellaneous filesystems --> Persistent store support (x) --> Log panic/oops to a RAM buffer (x))

<*>   Persistent store support
<*>     Log panic/oops to a RAM buffer

Define kernel cmdline parameters for ramoops (Boot options --> Default kernel command string)

mem=400M ramoops.mem_address=0x5BFFFFFF ramoops.mem_size=0x2C000 ramoops.record_size=0x4000

After a crash you need to mount pstore to check if any logs captured. I've added below to /etc/fstab for easy mount after.

root@R7800:~# cat /etc/fstab 
# <file system> <mount point> <type> <options> <dump> <pass>
pstore /sys/fs/pstore pstore default 0 0

Obviously messing with kernel_menuconfig parameters may at least softbrick your device so a working factory image + backup is highly recommended.

I have now 3d uptime with above parameters so it is not causing at least any severe issues by itself.

Take note on the other observations/considerations in the above discussions with qosmio.

Thank you for sharing. I'll have to try it out.
In the mean time it seems that a simple daily reboot will have to do

TCHAMMER · October 29, 2020, 7:34am

What about this Bug can this releated to the Random Reboots with the R7800 ?

The Workaround is to set the CPU governor to Performance.

johnnysl · October 29, 2020, 11:55am

I've been testing the latest availble code from Ansuals github. both original and rebased on top of the latest master.
I use the R7800 as a repeater where it is a client of my main workhorsee (Linksys WRT1900AC-V2)
it's connected via a dedicated SSID on 5GHZ. same radio has a second SSID that is identical to the one on the Linksys and thus i have the same SSID all around the house.
What i experience is that with the NSS offloading drivers enabled, wifi starts to stutter and speeds eventually drop to zero after about half a day. this happens when the client is on the linksys as well as on the R7800. First few minutes after connecting are ok, but after a few minutes the connections just slows and dies eventually.
An older Iphone 7 we have seems to suffer worse from it than the most recent Iphone, and the Laptop i have with an Intel AC chipset seems to be less effected, but eventually all show it.

Might anyone have a clue how to fix or tweak this. It might even be a bug in the linksys, that is triggered by some behavior of the NSS stack. no idea.

kirdes · October 29, 2020, 1:37pm

I'm not quite sure, if in your use case (AP repeater) NSS acceleration is actually involved.
But to make sure, you can disable the option "Enable NSS support for IPQ platform" (under kmod-mac80211) and give it a try.
Another possibility would be the debug mode of hostapd (https://openwrt.org/docs/guide-developer/debugging#wireless, loglevel)
Maybe there is something useful in the log.

johnnysl · October 29, 2020, 2:28pm

Ansuel's changes accelerate wifi as well. I don't really need the acceleration, but i just wanted to test the code to be able to give some more feedback

Anyone know if the port forwarding issue is still there? Do any of you have port forwards from wan to internal ip's active and working?

rog · November 1, 2020, 11:22am

I never had any port forward issues. I can access my router from wan through Wireguard and I can also access several internal cameras without any problem.

ACwifidude · November 1, 2020, 12:55pm

I never had any issues accessing devices either. I used the forward rule for a little while but didn’t notice a difference. I’m no longer using any custom firewall config.

keithspg · November 1, 2020, 6:54pm

Installed the latest from @ACwifidude this morning.
I did not wipe the config and had a lot of issues trying to use previously generated configs. At one point I lost all ipv4 connectivity. I reset it and started over and am now back up with a proper config for this build.

I have attFiber and the speed test is 920/930 or thereabouts, so the same as ddwrt with a recent build.

The only thing I have issues with is the ddns script. I use duckdns. The ipv4 works fine, but the ipv6 does not. The error in the log is:

Do I read this wrong? Does wget not understand ipv6?

ACwifidude · November 1, 2020, 7:36pm

I don’t use ddns so you might be missing some of the packages.

These should be the missing packages:


opkg update
opkg install ddns-scripts wget curl luci-app-ddns

Ansuel · November 1, 2020, 7:39pm

not related to this... it's a problem of ddns so pls report on github

keithspg · November 1, 2020, 9:47pm

@Ansuel Got it. @ACwifidude the ipv4 works just fine, it is the ipv6 which doe snot. All the packages are installed.

This build is blazing fast. Even the WiFi is faster. Will monitor to see how the stability is, but everything seems to be OK so far with the exception of ddns. It is strange because it worked on either Kong's or Hnyman's build. No biggie as all I really need is the ipv4 anyway, which works fine.

ACwifidude · November 1, 2020, 11:41pm

The NSS hardware offloading is awesome - glad you like it. NSS offloading is definitely the way to go for the r7800. OEM-like speed with the advantages of OpenWRT firmware.

It has been just as stable as master for me.

Tyco89 · November 2, 2020, 12:55am

I was cleaning up some logs and found this in the remote kernel log for my R7800
Seems to be work queue related, but I'm not an expert.
@Ansuel does this mean anything to you ?

@ACwifidude I see your build is re-based to the latest kernel. Anything changed in the NSS code?
Wondering if it is worth a new build, or should I use your image

ACwifidude · November 2, 2020, 2:25am

My build is:

all of the NSS commits on Ansuel’s branch
rebased on the latest master
with a simple set of packages (ex: luci, usb working, ipv6, stats)
nothing extra added. KISS principle.
easy, so that we can have a pool of quality testers to make the software better.

I’ve been using git cherry-pick as Ansuel adds features:

git fetch Ansuel && git cherry-pick enterhashhere

I then rebase with master (OpenWRT git is my upstream) and build off the diffconfig on my GitHub:

git fetch upstream && git rebase upstream/master

jack338c · November 2, 2020, 4:25am

hello @Ansuel
any good news for ea7500,I can't wait to get tested it

shelterx · November 2, 2020, 3:05pm

Rebasing to master doesn't work anymore (at least I couldn't), seems like there are too many changes.

ACwifidude · November 2, 2020, 3:37pm

I rebased yesterday. Are you getting errors while rebasing or while compiling?
