iwlwifi: Direct firmware load for iwl-debug-yoyo.bin failed with error -2

iwlwifi: Direct firmware load for iwl-debug-yoyo.bin failed with error -2

[Sedat Dilek]

Hi,

I am seeing this failed/error message for a long time:

[Sat Jul 25 13:03:28 2020] iwlwifi 0000:01:00.0: Direct firmware load
for iwl-debug-yoyo.bin failed with error -2

So, I started to look for the file "iwl-debug-yoyo.bin" in [1], but failed.
AFAICS this is a file for debugging purposes?

Why do I see such a message as an end-user w/o iwlwifi-debugging enabled?
For some end-users I can imagine this looks scary and they will look
into their cupboards and below their beds but will not find any
monsters.

I found a rename from an ini file to bin here:
commit 8d9e982bf9bf ("iwlwifi: dbg_ini: rename external debug
configuration file")

Is "iwl-debug-yoyo.bin" a binary or as before an ini (text) file I
have to configure somehow.

Does this need to be guarded by some "ifdef CONFIG_IWLWIFI_DEBUG" in
"drivers/net/wireless/intel/iwlwifi/iwl-dbg-tlv.c"?

Or does drivers/net/wireless/intel/iwlwifi/Makefile needs some tuning
- as said I have no iwlwifi debugging enabled via Kconfig?
...
iwlwifi-objs            += iwl-dbg-tlv.o

Please enlighten me/us?

Thanks.

There's an RFC patch about this:

https://patchwork.kernel.org/patch/11625759/

I think that should be applied. Intel folks, should I take that directly
to wireless-drivers-next?

As I wrote in the other thread, yes, please.  Go ahead and merge it.

Hey cool!

Thanks for taking care.

I have included this one into my Linux v5.8-rc7 patch-series.

Sorry, if I was a bit rude in my report.

Happy Monster hunting,
