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
