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.

Thanks,

Hi Ben,
Here is the output based on the latest git HEAD of your ct tree,
combined with the test firmware:
https://pastebin.com/raw/kwC6c18J
Hello,
The splat decode does not match the source code, so I'm not which is
correct.
OpenWrt seems to add custom patches to your source.
Please find the complete source in subsequent mail as being build.
Regards,
Koen

Also, please enable the firmware DBGLOG logging per instructions here:

This is the suggested level to debug at: 0xc0000032
Will do and will get back on this.
Thanks
Thanks,
