Hello BT folks,
Just so y'all know, the QCA6390 bluetooth hardware appears to be
broken
at least since commit 720261cfc732.
The KDE and Gnome bluetooth control panels appear to think there
is no
bluetooth hardware. Rolling back to 6.10 appear to function.
I have a Dell XPS13 9310.
I will attempt to capture some kernel logs in a bit.
git show 720261cfc732
fatal: ambiguous argument '720261cfc732': unknown revision or
path not
in the working tree.
I gave you the sha for the built fedora rawhide kernel package, not a
mainline sha. Sorry about that. I thought it was a mainline sha. I am
trying to bisect the problem. Hopefully, I can get a mainline git sha
for you soon.
If it helps, the build date of the kernel is 2024-07-19.
Sorry about the confusion. Hope this helps track down the problem.
I have managed to get the following commit id range for the issue:
80ab5445da6235..e2f710f97f35
Narrowed to 80ab5445da6235..586f14a6a182
i feel a little sad that QCA6390 of your machine are broken again.
i find out a doubtful point by checking recent changes.
you maybe have a attempt for below change if you would like to do that.

thanks
Yeah, I am sad that my bluetooth is broken again as well. I am trying
your patch now to see if it gets my hardware working. Will reply back
soon.

This patch does not fix the problem. The first broken commit is
9a15ce685706e73154. This patch effectively reverts only one part of that
patch.
FTR, I applied this patch on top of the parent commit of the first
broken commit. I will try it on the tip of mainline as well.
This patch doesn't appear to apply cleanly to the current tip of
bluetooth-next/master, so I can't really go further in testing it right now.
Also, so you know, Bartosz has said that he is aware of the regression
and is working on it.
Zijun, you should talk the folks at qualcomm and see if there is any
appetite for getting closer to the Linaro folks with regard to this
stuff. You have been very eager to jump in, and I see that Bartosz and
Luis also seem interested in fixing this. I do wonder if there a way to
take advantage of that to build a better working relationship in this
bluetooth space with qualcomm and the linux kernel devs.
If qualcomm would be interested in hiring a tech person to help with
this stuff. I am definitely interested in helping in this area.
Thanks,
wt
