Yeah, the ath1?k-firmware.git repos are being moved to
git.codelinaro.org and we will send an announcement once everything is
ready.

Thanks for letting me know, I was not aware any of this. Me and Jeff
will investigate and get back to you.

In case not everyone noticed but Jeff has now uploaded updates to
2.5.0.1 branch:

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/commit/97e0d33fe3e0f708459a682b167014906719337d

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/commit/04dd351414737ac14b3e381d3695b59f4de67eaa

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/commit/2dda8ce67f65af54f86fb2f49316174841fa95f7

It's quite strange that they updated 2.5.0.1 branch first but my
understanding that there should be updates for the newer 2.7.0.1 branch
as well (2.7.0.1 branch is also in linux-firmware).

Yes, I also told them in the support ticket that this is from an older branch 
than what is currently shipped in linux-firmware.git. But they told me 
that they are working on newer versions (whatever that means) - but they 
wanted to  handle first the update to ATH.11.4 (2.5.0.x) and then 
step-by-step release it for newer firmware branches. It seem like that would be 
up to 2.9.0.x - no idea why there is no (public) 2.10.x/2.11.x for the AP 
SoCs.

Kind regards,

I would like to point out that IPQ6018 doesn't even have anything
newer than 2.5.0.1 available publicly.

But I do see WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1 for IPQ6018:

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/tree/main/IPQ6018/hw1.0/2.7.0.1/WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1?ref_type=heads

And that release seems to be also in linux-firmware:

File: ath11k/IPQ6018/hw1.0/q6_fw.mdt
Version: WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1

Am I missing something? Or did you mean IPQ5018 which only has a release
from 2.6.0.1 branch?

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/tree/main/IPQ5018/hw1.0?ref_type=heads

Ah yes, sorry for the confusion, I meant to say newer than 2.5.0.1
that actually works.
All of the newer public FW than 2.5.0.1 that we tried in OpenWrt will
just crash, we had the same issue with 2.6 and 2.7 FW on
IPQ8074 and it was fixed in 2.9.0.1 but there is no 2.9.0.1 public for IPQ6018.

Robert

Ah, is the issue you are talking about this bug:

https://bugzilla.kernel.org/show_bug.cgi?id=216515

Yeah, that is the issue for IPQ8074, we just skipped the 2.6 and 2.7
FW and went for 2.9.

For IPQ6018 it seems that we have BDF compatibility issues with most
FW newer than 2.4 or 2.5 max.
Its been some time since I last checked what boards work with what FW
on IPQ6018.

Robert

Yes we wasted a good time on that and we concluded that
2.6.0 and 2.7.0 introduced breaking change in how the BDF was parsed
that were fixed in 2.9.0 restoring support for legacy BDF.

I think almost all ipq60xx suffer from this... Only a Qnap 301 worked with
2.6.0 - 2.7.0 (that was ipq807x)

Just as info: The non-public QCA ticket was simply closed on Tuesday (without 
having any upload which works for Robert and is from the same/newer branch 
than what is currently in linux-firmware.git). So maybe we are actually out of 
luck.

Now they are (indirectly) claiming that WLAN.HK.2.9.0.1-* is for ath12k. You 
can actually read the response like everything newer than WLAN.HK.2.5.0.1-* is 
for ath12k. Maybe I missed something and somebody can point out my error. Btw. 
their ATH.11.5 release already a newer version than WLAN.HK.2.5.0.1-*.

And maybe someone else known why there is a WLAN.HK.2.11.0.1-* and 
WLAN.HK.2.10.0.1-* [1] for IPQ9574 but not for any other 802.11ax HW. Maybe it 
has to do with the fact that it is used together with 802.11be HW (PCIe, 
QCN9274?) and is therefore still actively maintained?

Kind regards,
