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,
Ben
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.
I did look in that code, and that is where I saw the mismatch. Please
check your own local system
and see if the splat matches your code? Maybe I made some mistake of
course...
You can paste ~20 lines of code around the proper splat line and then
I can find it in my
source...
Thanks,
Ben
Hi Ben,
Just retried again on a slightly older commit (2019-05-08) and the splat
points to another location now.
When looking it up, it again points to the WARN_ON pointed below ..
Checking shows that all calls to ath10k_mac_vif_beacon_free() calls are
way above this line (highest line nr is around line1970)
I currently can't explain where the mismatch comes from ..
Current build below is just the git HEAD of openwrt 19.07 branch,
cloned, build and flashed without any modification.
