ath10k firmware-6.bin bug: Disconnections every 20 minutes on QCA6174

ath10k firmware-6.bin bug: Disconnections every 20 minutes on QCA6174

[Kouroche Bouchiat]

Hey,
On hw3.0/firmware-6.bin my QCA6174 seems to be dropping 100% of
packets after exactly 20 minutes. I talked to people over on the
Archlinux forums who suggested to force the kernel to load
firmware-4.bin instead. I did just that ("mv firmware-6.bin
firmware-6.bin.bak") and my connection seems to be working fine now.
The forum thread is the following:
https://bbs.archlinux.org/viewtopic.php?id=228793

dmesg doesn't appear to show anything significant but I've provided it
just in case (w/ lspci -k):

I suspect that this is a WPA rekeying problem, are you able to verify
that? Anyway, I reported this internally.

Hi, thanks for your answer.
I tried from a fresh install, directly with the last linux-firmware
package and the issue in avaliable at the first boot.

That does not answer my question if it's WPA rekeying related but let's
forget that for now.

Can you try this firmware:

https://github.com/kvalo/ath10k-firmware/blob/master/QCA6174/hw3.0/4.4.1/firmware-6.bin_WLAN.RM.4.4.1-00026-QCARMSWP-1

If you try it, double check that you are really testing the correct
firmware version, it's pretty easy to use the wrong version. Even better
if you can provide me the desmg output so that I can confirm that.

I'm using qca988x hw2.0.
Do you want that I replace the
/usr/lib/firmware/ath10k/QCA988X/hw2.0/firmware-5.bin with the
QCA6174/hw3.0/4.4.1/firmware-6.bin you gave me?

I'm confused, the subject says this is about QCA6174 but now you are
saying this is on QCA988X?

Ah, now I understand. You got confused between different threads. This
is a public mailing list and there are multiple ongoing discussions
("threads) going on and one has to be careful not to mix them. This
thread is:

http://lists.infradead.org/pipermail/ath10k/2017-August/010005.html

But your thread is again here:

http://lists.infradead.org/pipermail/ath10k/2017-August/010042.html

So two very different issues.

I was told that 4.4.1 firmare should have a fix for this. Please let me
know if you can confirm that and then I'll update the firmware in
linux-firmware.

Yes, WPA rekey is initiated periodically by the AP. Some APs have a
setting in UI to configure the period but not all. But don't bother to
changing WPA rekeying time that as I'm optimistic that 4.4.1 branch has
a fix for your issue.

I'm sorry about my previous email. I forgot to disable HTML formatting.
Been testing the 4.4.1 firmware for around 40 minutes and no
disconnections so far. It's looking great. dmesg tells me it's been
correctly upgraded:

This is enough, thanks. I added an item to my todo list to update the
firmware in linux-firmware.

BTW, the unknown event ids are annoying. Anyone want to submit a patch
to fix (silence) those?

ath10k_pci 0000:02:00.0: Unknown eventid: 90118

Re: ath10k firmware-6.bin bug: Disconnections every 20 minutes on QCA6174

[Adrian Chadd]

Hi,

I'd rather see the ones that are known-to-be-ok-to-ignore be ignored.
I've been bitten by unhandled firmware IDs that I had to backfill
whilst doing driver bring-up / QSDK patch porting. :-)

(And honestly, if I were to submit a patch, it would be to log the
actual event ID and flags in a way you can grep for it, versus the
above format where the high bits are set to say they're a
notification, etc.)

Absolutely and that's what I meant. But I think there was a discussion
before that I least one event was ok to ignore (I have forgotten the
details already).
