backports for wifi-7 and kernel 6.5

backports for wifi-7 and kernel 6.5

[Cristian Cimpianu]

Hi guys,

I've been working on a project using the backports project to build some custom wifi modules for different kernel versions.
Now the customer wants to do a wifi-7 chip keeping the infrastructure the same as much as possible. But wifi-7 has been added into kernel 6.5, while the backports project is still at 5.15. And the customer wants that in like 6 months.
So, in the hope I will understand better what would be the easiest solution, I figured I could ask here.
Is there a plan to add support in the backports project for kernel 6.5 or for the wifi-7 changes to the mac80211 and cfg80211 modules?

best regards,
Cristian.

Christian,

I do not know the details, but Brian Witte (Cc'd here) recently informed me that 
Felix Flietkau has a backports tree for kernel 6.5.

Cristian,

I was asking questions on #backports IRC channel since I also am trying to get a
more up-to-date backports release. I had started patching from 5.15 and was
making some progress, but it was going slower than I'd like and then Hauke
shared this tree with me:

https://github.com/nbd168/backports

It appears to be on 6.5, I have only pulled the code at this point and haven't
fully tested it since we had a holiday here in US and I have been traveling and
with family.

Felix is maintaining that tree for OpenWrt from what I have been told.
You can see various 6.x backports tarballs here if you search "backports":

https://mirror2.openwrt.org/sources/

I am going to be digging into this for Realtek backports repos that Larry and I
work on. It seems like there is some renewed interest in backports these
days, haha.

Let me know if I can help in any way as I am working on similar problems.

I will report back if any issues come while working with Felix's tree. I am very
grateful it was shared with me to say the least...

Thanks a lot guys.

That tree seems to have contributions from all the right people and it seems to generate a working 6.5 tree.

br,
Cristian.
