Netgear R7800 exploration (IPQ8065, QCA9984)

Hi Hyman, following you from the beginning with WNDR3700v2 and now decided to follow also with R7800 which I bought a few days ago.
I want to thank you for the great work you are doing on this router.
I'm successfully compiling your build for R7800 LEDE snapshots and successfully upgraded the firmware from stock to LEDE without problems.
Unfortunayely having problems with leds. In fact 2ghz and 5ghz are wrongly driving the wifi on/off and wps leds instead of the rigth ones.
I read the thread and at the beginning was said that your build has a workaround for this problem, but it seems not to have worked for me. I obviously followed all steps for the building of the the compiling environment.
Can you please explain how to apply the workaround so that it will stay there each time I build a new release?
Thanks in advance for your kind help.
EDIT: I misunderstood the workaround. I realized that 2 and 5ghz leds still not being supported by current drivers.

Good that you figured it out.
Sadly the proper wifi LEDs in R7800 still can't be controlled by opensource ath10k drivers, so I use the wifi on/off and wps LEDs as the workaround to have at least some wifi activity indication.

@hnyman @mroek @tetsuo55 wonder if it fixes rx ring buffer corruption
https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=pending&id=f35a7f91f66af528b3ee1921de16bea31d347ab0

Interesting. Can we get this added to the master tree?

@Magnetron1.1
Could you post syslog output of ath10k wireless cards initialisation, maybe there are different revisions

@hnyman
Hi,i download "R7800-lede-r4751-4b3ffecf2b-20170828-1827-sqfs-sysupgrade.tar" from you dropbox. but 5G wireless still has problems.

@hnyman do you have buffer sizes restored in that build?
@tetsuo55 is running my build for more than 7 days without issues already, while before it has been 1-2 days till crash

No, r4767 build contains the rx ring fix, but not the buffer size change:

A  package/kernel/mac80211/patches/332-ath10k-fix-rx-ring-buffer-memory-leak.patch

In my build I also have buffers restored and this PR applied


Could you please make a test build as well to verify what combo fixes it?

I've been running the r4751 rxring test build and my 5GHz still crashes after a day or two.

My logs show a bunch of different error messages like this:

Having fun at the moment porting all the NSS related HW acceleration code from codeaurora, it's a long slog but I've now got most of qca-nss-ecm, the connection manager that handles offloading processing to NSS, compiling, just need to track down a few more patches that need applying.

lede-r4773-12930fc045-20170831-rxring-buffersize-pcie-test

I made a test build that contains all three fixes under discussion:

  • this QSDK pcie fix set
  • rx ring memory leak fix
  • remove ath10k buffersize reduction patch (in order to have same buffersize as in 17.01)

The r4750 "official" build (Aug 30) and the r4723, r4767, and r4773 hnyman builds have the MAC error problem on my router. The MAC error occurred so frequently on r4773 that the web GUI was useless. Had to use TFTP to restore r3498 (4.4 kernel) and all is well again. I'm beginning to think that there may be a timing "hole" or "window of vulnerablity" when using the Atheros Wi-Fi drivers with the 4.9 kernel.

Weird enough, but I have similar issues on 2.4 ghz only - broken GUI - wrong styles and buttons (looks indeed like frames corruption), but 5ghz is perfectly fine

Please, post your ath10k init log, it could be different qca9984 revisions in the same model (for different countries?) that may require different board data files like @chunkeey suspects.

edit: @hnyman does your 3498 build includes cal -> pre-cal fix? If yes then it’s not board data after all.

Yes. My 17.01 build includes the calibration data reading fix.
But official 17.01 releases do not.

=====================================================================

I see the error -2 on DD-WRT firmwares and so far nothing horrible has happened to my routers.
Is the "user helper" loading the pre-cal data or are the Atheros drivers assuming built-in defaults?

Update 1
After searching the all-wise, all-knowing internet, I can now answer my own question.
Error -2 means the kernel could not directly find the pre-cal data and firmware files and called upon a user space helper to find them which was successful. It seems strange that the 4.9 kernel had trouble with this, but the 4.4 kernel didn't.

  • Magnetron1.1

This a great post from another thread on issues with this device when using the 4.9 kernel. I'm just bringing it over but the credit all goes to Megnetron1.1:

Following @LuisGC idea about using ethtool, I was able to overcome the MAC error problem with the r4773 build.
Install ethtool (opkg install ethtool) and experiment with the br-lan interface since it is the center point for most of the other interfaces.

First list how this interface is configured before changing anything:

root@R7800RT1:~# ethtool -k br-lan

Features for br-lan:
rx-checksumming: off [fixed]
tx-checksumming: on
	tx-checksum-ipv4: off [fixed]
	tx-checksum-ip-generic: on
	tx-checksum-ipv6: off [fixed]
	tx-checksum-fcoe-crc: off [fixed]
	tx-checksum-sctp: off [fixed]

tx-vlan-stag-hw-insert: on
rx-vlan-stag-hw-parse: off [fixed]
rx-vlan-stag-filter: off [fixed]
l2-fwd-offload: off [fixed]
busy-poll: off [fixed]
hw-tc-offload: off [fixed]

Notice how most of the tx settings are "on". Try setting them "off".

root@R7800RT1:~# ethtool --offload br-lan tx off

Actual changes:
tx-checksumming: off
	tx-checksum-ip-generic: off
tcp-segmentation-offload: off
	tx-tcp-segmentation: off [requested on]
	tx-tcp-ecn-segmentation: off [requested on]
	tx-tcp-mangleid-segmentation: off [requested on]
	tx-tcp6-segmentation: off [requested on]

Now re-run the "tree /" test (which fails every time for me on r4xxx builds).

root@R7800RT1:~# tree /
The entire tree is displayed followed by
12302 directories, 61309 files

Although I took a "shotgun" approach, so far these changes haven't had much impact on performance, but could possibly be refined.

Unfortunately the ethtool changes won't survive a router power-cycle or reboot.
To fix that, on LuCi go to System => Startup and in the box under Local Startup insert the ethtool syntax.

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
ethtool --offload br-lan tx off
exit 0

These changes should hold unless the router's firmware is overwritten, then the ethtool will need re-installing.

That's the good news; now for the bad news which has nothing to do with ethtool.
Has anyone noticed that the r4xxx builds (4.9 kernel) have poor Wi-Fi performance? Install iperf3 (opkg install iperf3) and test with one of my octacore HP laptops configured as an iperf3 server (iperf3 -s) on the 5GHz radio. Router is still on r4773. The router antennas are 4 feet from the laptop's Wi-Fi dongle.

Notice the low transfer and high retry count.

What tcp congestion algorithms are on this router?

root@R7800RT1:~# sysctl -a 2>/dev/null|grep congestion
net.ipv4.tcp_allowed_congestion_control = cubic reno
net.ipv4.tcp_available_congestion_control = cubic reno
net.ipv4.tcp_congestion_control = cubic

So "cubic" is the default; try "reno".
