Hi Ben,
Hi All,
So I'm going to give this another try ..
As the IBSS functionality is heavily advertised as a delta to
mainline, it would be very nice to get it working also :)
Testing the latest ath10k-ct driver and firmware seems to be a step
back compared to roughly a month ago.
I'm currently seeing the firmware crashing, which was not the case
before:
ath10k-ct + htt-fw:
https://pastebin.com/raw/7Sy9yx6s
Looks like firmware ran out of some WMI event buffers and crashed
instead of handling
it more gracefully.
Please try the attached (untested) firmware and see if it behaves
better.
Hi Ben,
1 step forward here.
I'm not seeing crashes anymore using the test-firmware.
https://pastebin.com/raw/4ZeXu7iw
I've linked up 2 IBSS devices (wave 1, VHT80)
OLSR traffic (UDP) works and packets here are nicely going back & forth.
Simply pinging (ICMP) between the 2 devices does not work.
When sending 100 pings, (64 byte large) sometimes 1 gets through ..
but with a latency of > 500ms
I think if the splat and the beacon spam below could be fixed .. this
would be a major step forward:

Please look in your code and let me know the source around the line in
mac.c (6563) that is splatting.
Also, you might grab the latest ath10k-ct repo, it has a tweak that
might fix the SWBA overrun
messages.

Hi Ben,
Here is the output based on the latest git HEAD of your ct tree,

Thanks for your swift reply so far and the test-firmware.

ath10k-ct + non-htt-fw:
https://pastebin.com/raw/bqVqQmXq
Mixing upstream ath10k driver with the non-htt CT fw does not work.
Errors are seen here regarding missing IE's and stuff.
Also IBSS functionality is not shown when running 'iw list'
IBSS requires ct driver plus ct firmware, at least.
Ah, ok. :-)
Thought it was possible based on this one :
https://www.spinics.net/lists/linux-wireless/msg137827.html
I'd expect the regular driver to work in normal STA/AP mode, though
it would likely
warn about IEs. Should be warning only though.
Thanks,
Ben
Kind Regards,
Koen
