Subject: chan info: invalid frequency 0 (idx 41 out of bounds)
Date: Fri, 09 Jun 2023 13:41:16 +0200	[thread overview]
Message-ID: <CT83B4WXR0TL.3OREBDGKBT2IM@otso> (raw)

Hi all,

I'm seeing a problem(?) since a while with the following warning being
printed to dmesg regularly when running on sm7225-fairphone-fp4 with
e.g. v6.4 kernel:

[   44.891535] ath10k_snoc 18800000.wifi: chan info: invalid frequency 0 (idx 41 out of bounds)

To be clear this is not a regression, from what I recall I've always
seen this warning happening since bringing up wifi on this board, also
with older kernel versions.

Enabling some debug log for chan info shows the following behavior:

[   48.803969] ath10k_snoc 18800000.wifi: chan info: invalid frequency 0 (idx 41 out of bounds)

So from what I can tell this firmware sends freq 0 info, then
freq_to_idx loops through the freqs and we arrive at the max value
ATH10K_NUM_CHANS (41).

Has this behavior been seen before or is this (to your knowledge)
limited to this board?

Anyone got an idea?
