Ipq806x NSS build (Netgear R7800 / TP-Link C2600 / Linksys EA8500)

Try xfsprogs. Not sure about it and might be overkill, but may get you working and you can start trimming down from there.

Thanks now NFS and XFS working

Hi, I stumpled over the same error while compile an initramfs for the Netgear AX12/RAX120v2. Not sure it's still relevant for you guys.

After search git log for CCMP I found the following commit:

commit d19144240c451c665eb235432804973cd603a69b (HEAD -> ipq807x-5.15-pr)
Author: Hauke Mehrtens <hauke@hauke-m.de>
Date:   Sat Aug 20 22:51:29 2022 +0200

    iwinfo: update to latest HEAD

    0dad3e6 Add support for CCMP-256 and GCMP-256 ciphers

    Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

After cherry-picking that commit (and resolving a simple merge conflict which was updating the iwinfo commit used) compiling worked fine.

Is it possible to change WLAN MAC addresses on this firmware? Change in luci has no effect.

qosmio · 2022-10-30T20:32:32.726Z

Not sure if you're still looking into this but I have a fix (ipq806x: Fix Reference to non-existent node or label "smb208_s1b") on my 5.15-qsdk11 branch.

Side note: Could I get a rough tally of folks still testing my branch? @Ansuel's Krait Clock Controller patches look to have been merged into master now (making my 5.15-qsdk11-new-krait-cc redundant). However it's been very unstable with the NSS packages, at least for me. Uptime has always been a max of 22-24 hours. I'm going to try a build without it to test out. Wondering what everyone else's experiences have been.

Hitmann · 2022-10-30T22:15:59.626Z

Not sure if it has anything to do with it, but this version with ath10x flavor and performance gov no longer randomly reboots on ea7500v1. 18h uptime so far. Nice.

LE: There was this post a while back regarding power/thermals on a r7800, and i can confirm this in my ea7500v1 i measured it's amperage, setting cpu to performance is very negligeable power increase of about 5% more, while disabling the 2.4g AP decreases power consumed by almost a quarter. The 5g AP must have it's power circuitry on since disabling that barely reduces consumption by 1-2%.

If I'm not wrong then the 2 branches (5.15-qsdk11 & 5.15-qsdk11-new-krait-cc) should be the same, right?
I ask because until a few days ago I have been using the 5.15-qsdk11-new-krait-cc branch and I abandoned it due to the continuous reboots that occurred (from 30 minutes to 24 hours maximum).
3 days ago I installed the new firmware from the 5.15-qsdk11 branch and it's already been over 80 hours without reboots.

If I'm not wrong then the 2 branches (5.15-qsdk11 & 5.15-qsdk11-new-krait-cc) should be the same, right?

They are "almost" the same. The main difference between the two are the NAPI changes that we were testing for wifi latency, and I believe some patch consolidations were made by @Ansuel upstream.

I installed the new firmware from the 5.15-qsdk11 branch and it's already been over 80 hours without reboots.

I hadn't made too many changes to the 5.15-qsdk11 branch aside from just keeping it in sync with master, and only recently synced when the krait cc patches were also merged upstream.

If you haven't already pulled in latest commits, could you give me the commit you're on for my 5.15-qsdk11 branch?

I'm still running 5.15-qsdk11-new-krait-cc but after numerous reboots and even complete lock-up I've switched to performance governor and there are no reboots nor stalls since then.

ACwifidude · 2022-10-31T15:46:06.434Z

Thanks! Those patches work great. Looks like nss-drv is throwing some errors. I'm trying to make the diffconfig as simple as possible so maybe excluding some of the lines is causing more complaints in my build process. nss-drv is complaining about these lines and then subsequently fails to build - does it complain in your building but make it through because of your diffconfig settings?

Could you check it please?

I performed settings reset but I still got broken macs FE:FF:FF:FF:84:FE for wan FE:FF:FF:FF:00:00 for lan. The original openwrt has correct macs: 74:DA:38:xx:xx:xC for wan 74:DA:38:xx:xx:xD for lan So it's definitely something with this firmware.

ACwifidude · 2022-10-31T22:48:26.983Z

That is interesting. The dts patch only makes minor changes to the gmac section that shouldn’t change your MAC address on quick glance.

Everything else function normally?

tishipp · 2022-10-31T22:48:52.537Z

Do you have a panic log?
I will try to build and test.

SopaDeMacaco-UmaDeli · 2022-10-31T23:19:55.358Z

I think so. Wlan addresses are correct on both vanilla and nss builds, only wired addresses are weird.
Here are some kernel logs.

dmac_clean_range

Are you building from my 5.15 branch or just using the nss packages from my repo? Those functions should be in target/linux/ipq806x/patches-5.15/999-001-Revert-ARM-dma-mapping-remove-dmac_clean_range-and-d.patch

That looks to have the krait clock controller patches. And further inspection shows no patches were submitted for 5.15 ip806x, most of the changes are just refreshed patches.

You said you're running in performance mode? I just built from master on 5.15.76 going to experiment with a few ondemand thresholds before trying performance.

@tishipp

Do you have a panic log?

Yup, two currently

qosmio:

You said you're running in performance mode?

No. I'm running 'ondemand'.

If, in addition to including the patch that qosmio mentioned above, you modify the diffconfig by adding these lines to your diffconfig

# CONFIG_PACKAGE_kmod-pppol2tp is not set
CONFIG_PACKAGE_kmod-qca-nss-crypto=y
CONFIG_PACKAGE_kmod-qca-nss-drv-igs=y
CONFIG_PACKAGE_curl=y

you will make success.

EDIT: But what is more curious is that once you have compiled the firmware, you can successfully compile it again by commenting the following lines in diffconfig:

# CONFIG_PACKAGE_kmod-qca-nss-crypto is not set
# CONFIG_PACKAGE_kmod-qca-nss-drv-igs is not set

or just only commenting one of them.
It seems that there is a dependency problem between the different parts of the NSS package.

Thanks for looking at that. I remember seeing this dependency issue a while back. I hadn’t revisited it since I started selecting all non-essential NSS packages as modular <M>. Even though my setup doesn’t require any of the ppp/pppoe/ipec etc packages, I wanted to be sure it builds for others.

I’ll look into tweaking this when I get the chance. Dependency tracking in buildroot is pretty frustrating to lock down, to say the least...
