Please provide this info. See this link for more info on how to gather debug

Description of the problem (how to configure, how to reproduce, how often it happens).
Wifi is up. i compile your kernel, install on Ubuntu 20.04 after i change regdomain in advanced configuration
cat /lib/firmware/ath10k/fwcfg-pci-0000:06:00.0.txt

regdom = 840

Did it work better before on some earlier version of ath10k-ct driver/firmware?

[gsustek]

it works stable on same ubuntu 20.04 and

[gsustek]

wanna use 5.8 because it is the next LTS kernel

[greearb]

Ok, so 5.4 ath10k-ct driver works fine, but the 5.8 version works poorly? Can you try stock 5.8 kernel to see if it is specific to my driver or if 5.8 is broken in other ways?

[greearb]

And, did you compile my 5.4 driver into your 5.8 kernel and that works OK?

[gsustek]

Ok, so 5.4 ath10k-ct driver works fine, but the 5.8 version works poorly? Can you try stock 5.8 kernel to see if it is specific to my driver or if 5.8 is broken in other ways?

Ok, so i tried almost every stock kernel driver from kernel 5.0 and up 5.8.5 with kvalo board.bin and latest firmware 114. Every version of 5 kernel is broken in such a way that maximal (up and down)-load is max about 40MB/s and there is 10% of ping loss. Configuration on ubuntu of 18.04 is the same as on 20.04 which is just regular upgrade on the same kernel version. The latest stable ping is on ubuntu 18.04 , kernel 4.15.0-116.117 | Ubuntu-4.15.0-116.117 | 4.15.18 on stock driver. I compile on that same ubuntu 18.04 your linux-5.4-ct kernel which is also stable there and on migrated 20.04. so i tried to compile your last 5.8-ct kernel on ubuntu 20.04 with the same expectation for ping as on 5.4-ct kernel...but without of ping luck :-)

[gsustek]

And, did you compile my 5.4 driver into your 5.8 kernel and that works OK?

will try it now against your linux-5.8-ct kernel

[gsustek]

can't compile..

please help.

Sorry, I don't have time to work on that right now. Maybe you can try the 5.7 driver and see if it will compile?

[gsustek]

5.7 is compiling. sou should i try with that?

[greearb]

yes

[gsustek]

ok, i did some testing on your 5.8.0-ct kernel with wifi driver version ct5.7 and ct5.4.
On version 5.7, ping is terrible as on 5.8. With driver 5.4 and kernel 5.4 it is much better but not as 5.4 on 5.4 kernel which is flawless.
So on 5.4 i got fair dowload and upload with 5% ping loss.

What works flawless? Can you find the smallest change between flawless and not so flawless?

[gsustek]

ok, so for me flawless is ping 100% success and upload & download at least 70MB/s.
5.4.0-ct linux - flawless
5.8.0- ct- linux - 5.4-ct driver 3%-5% loss in ping, ok up/down
5.8.0- ct- linux - 5.8-ct driver terrible ping, up&down

[greearb]

Maybe just stay with 5.4 now. We'll do some testing on our 5.8 (or maybe 5.9) kernel as part of this dev cycle and maybe we can find the issues. If you feel like poking, try disabling ATF and related features and see if that improves things?

[gsustek]

Yes, i'm open for testing, eg. poking.
How can i control airtime fairness on QCA9984? please advise.
Thnx,
Goran.

[gsustek]

ok, i figure out, compile hostapd-ct with airtime config enabled. I disable ATF on kernel 5.8 with driver 5.4, but ping is still terrible, 5% of loss.
Any other suggestion?

[greearb]

See bug 153 and try to revert that driver change related to DMA and see if that helps?
