In that course I unfolded some state machine bits, which resultet in code duplication and some other complications. Fast forward, I just undone some of that in main. This is probably one of the more risky changes as of late. I tried to test it but as we also have learnt in the last years, the testing of many will reveal problems more likely than me trying to test in my limited capacity. So please all test main now! Prepare yourself in case of trouble (boot envorments, or otherwise, in case you need to roll back know how to). Let it run for a few hours or a day or two and then please report back if it is still working without extra troubles compared to before. In case you hit any hiccup please report right away! I will try to reply promptly (I do sleep occassionally) but real life currently also takes some share so it may be a day before I get to the emails. Please include driver and chipset/firmware you are using if possible along with any possible problem report. Why is this important (now)? There'll be follow-up changes needed to get the iwlwifi update into main as well so that all drivers are on the same level (v6.19) for a change again. The reason this is important now is that this will be our base for 15.1-RELEASE so we will have 6ish weeks still to sort out any problems. In addition (bonus points) if things go smoothly there is the next branch waiting for me to merge to bring further improvements still during March (at least to main and possibly stable/15). What if you are on stable/15? I believe you could just grab the last changes and merge them yourself. I will go and have a look and try to merge anything I can Thu or Fri (before the weekend) to keep the diff minimal in case that helps! Lots of health! Bjoern -- Bjoern A.

If that persists to be good, that would indeed be a fantastic outcome of th= is! :)

I only get the bug reports.
The thanks should still go to the FreeBSD Foundation!

Hi,

about 3 years ago, some of you may remember, we were hunting down the
constant (firmware) crashes with iwlwifi due to net80211 not playing nice
and the LinuxKPI 802.11 sta state machine not able to deal with it to make
the firmware happy.

In that course I unfolded some state machine bits, which resultet in code
duplication and some other complications.  Fast forward, I just undone some
of that in main.  This is probably one of the more risky changes as of late.
I tried to test it but as we also have learnt in the last years, the testing
of many will reveal problems more likely than me trying to test in my limited
capacity.



So please all test main now!

Prepare yourself in case of trouble (boot envorments, or otherwise, in case
you need to roll back know how to).
Let it run for a few hours or a day or two and then please report back if
it is still working without extra troubles compared to before.
In case you hit any hiccup please report right away!
I will try to reply promptly (I do sleep occassionally) but real life
currently also takes some share so it may be a day before I get to the
emails.
Please include driver and chipset/firmware you are using if possible
along with any possible problem report.



Why is this important (now)?

There'll be follow-up changes needed to get the iwlwifi update into main
as well so that all drivers are on the same level (v6.19) for a change
again.  The reason this is important now is that this will be our base
for 15.1-RELEASE so we will have 6ish weeks still to sort out any problems.

In addition (bonus points) if things go smoothly there is the next branch
waiting for me to merge to bring further improvements still during March
(at least to main and possibly stable/15).


What if you are on stable/15?

I believe you could just grab the last changes and merge them yourself.
I will go and have a look and try to merge anything I can Thu or Fri
(before the weekend) to keep the diff minimal in case that helps!


Lots of health!
Bjoern
