Subject: [PATCH v4] wifi: ath12k: report tx bitrate for iw dev xxx station dump

The tx bitrate of "iw dev xxx station dump" always show an invalid value
"tx bitrate: 6.0MBit/s".

To address this issue, parse the tx complete report from firmware and
indicate the tx rate to mac80211.

After that, "iw dev xxx station dump" show the correct tx bitrate such as:
tx bitrate: 104.0 MBit/s MCS 13
tx bitrate: 144.4 MBit/s MCS 15 short GI
tx bitrate: 626.9 MBit/s 80MHz HE-MCS 6 HE-NSS 2 HE-GI 0 HE-DCM 0
tx bitrate: 1921.5 MBit/s 160MHz HE-MCS 9 HE-NSS 2 HE-GI 0 HE-DCM 0

Please use full englist words like transmit instead of tx. Also the
title could be simplified to:

wifi: ath12k: report station mode transmit rate to user space

Here I assumed this only works in station mode. Or does this also
support AP and P2P mode? The commit message should explain that.

Now there would be two very similar functions:

ath12k_mac_he_gi_to_nl80211_he_gi() vs ath12k_he_gi_to_nl80211_he_gi()

ath12k_he_ru_tones_to_nl80211_he_ru_alloc() vs ath12k_mac_phy_he_ru_to_nl80211_he_ru_alloc()

Why do we need those?

Should we print a warning here? Otherwise we might miss something.

I think like this you could avoid the goto:

if (ar->last_ppdu_id != 0) {
if (ar->last_ppdu_id == ts->ppdu_id ||
ar->cached_ppdu_id == ar->last_ppdu_id)
ar->cached_ppdu_id = ar->last_ppdu_id;

ath12k_dp_tx_update_txcompl(ar, ts);
}

ar->last_ppdu_id = ts->ppdu_id;

Please don't add new function to the end of file, rather to the
beginning or the middle. But like I mentioned earlier, do we really need
these new functions?

Yes, you're right, we don't need these functions. i will delete these
functions and directly modify ath12k_he_gi_to_nl80211_he_gi() and
ath12k_he_ru_tones_to_nl80211_he_ru_alloc() in next version.
Thanks for pointing out.

After rereading my comments maybe keep the title simple like:

wifi: ath12k: report station mode transmit rate

But it would be good to clarify in the commit message what modes this is
supported. And what hardware families support this.

Hi kalle, Could you please offer your opinion on this commit message?

wifi: ath12k: report station mode transmit rate

Currently, the transmit rate of "iw dev xxx station dump" command always
show an invalid value.

To address this issue, ath12k parse the info of transmit complete report
from firmware and indicate the transmit rate to mac80211.

This patch only applies to the WCN7850's station mode.

After that, "iw dev xxx station dump" show the correct transmit rate.
Such as:
tx bitrate: 104.0 MBit/s MCS 13
tx bitrate: 144.4 MBit/s MCS 15 short GI tx bitrate: 626.9 MBit/s
80MHz HE-MCS 6 HE-NSS 2 HE-GI 0 HE-DCM 0 tx bitrate: 1921.5 MBit/s
160MHz HE-MCS 9 HE-NSS 2 HE-GI 0 HE-DCM 0

Looks good, except for readability I would add an empty line after "Such
as:".

I noticed that the signal patch depends on this patchset:

https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/

In that you should submit both patchses in same patchset. But please
wait until I have reviewed the signal strength patch.

Hi, kalle,

Would you mind if I kindly inquire whether you might have forgotten to
review "wifi: ath12k: report signal for iw dev xxx station dump" patch?
After you review, I can put the two patches into the same patchset:)

I don't rely on my memory and instead use patchwork for that:

https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches#checking_state_of_patches_from_patchwork

And the patch you are referring is in state 'New':

https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/

So it is in the queue, please just wait patiently.

And as general comment to all Qualcomm engineers (not just Lingbo): if
you want patches reviewed and applied faster then help Jeff and me!
Review other patches, test our drivers and stack, investigate bug
reports, make sure all firmware releases are uploaded etc. There is so
much to do. Don't just throw patches over the wall and disappear.

Hi Kalle,
Please ignore the patches submitted separately below.

[PATCH v4] wifi: ath12k: report tx bitrate for iw dev xxx station dump
[PATCH] wifi: ath12k: report signal for iw dev xxx station dump
[PATCH] wifi: ath12k: add display tx and rx bitrate for 11be

I will resubmit these patches in same patchset:)
