Hello,
we are using backport-iwlwifi core45 drivers and latest AC9260
firmware binary blob:
latest firmware available in Intel iwlwifi firmware fork:
https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/commit/iwlwifi-9260-th-b0-jf-b0-46.ucode?id=4bebf45872a9818a17e2079118500030a8fa377a
2019-11-28 iwlwifi: update FWs to core47-142 release
At runtime, we noticed these log traces:
iwlwifi 0000:01:00.0: Found debug destination: EXTERNAL_DRAM
iwlwifi 0000:01:00.0: Found debug configuration: 0
iwlwifi 0000:01:00.0: Allocated 0x00400000 bytes for firmware monitor.
So it seems that it is a debug firmware...
Q0) can you please confirm that we can safely use this debug firmware
in our product ?
Q1) is debug mode deliberately enabled in newer firmware or is it an
error (maybe like forgotten to disable it) ?
Q2) is there an impact on performance with this debug firmware ? WiFi
speed/throughput may be reduced or not ?
Q3) moreover, can you please confirm whether or not WoWLAN (aka
Wake-on-WLAN) is working with this debug firmware ?
Q4) is WoWLAN working with any AC9260 firmware version ? and any
iwlwifi driver version ?
Thanks for your help,
@team
Hello, do you have any news about the issue?
Best regards.

Hello, we really wonder if the version of the firmware we use is the right one.
I put Luca Coelho in copy according to his activity on git about
firmware: thank you for your help Luca.
Best regards.
@team.

You can use this firmware. It's a production firmware and not a
debugging version.

It is deliberately enabled. We enable some debugging options by
default so they can be extracted if needed.

No, there isn't any impact on performance.

WoWLAN should work fine with this firmware.

It has been supported for many years now. AC9260 got support for this
from the first version of the driver/FW that were publicly released.
HTH.

Hi there, did you had time to look at this issue? Thanks again.
