Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:
> On my new XPS 17 9730 laptop, I recently installed the Kernel 6.5-rc3. I noticed, however, that during its operation, the laptop was getting significantly warmer than before. I did some analysis using the 'stress' tool to measure and compare the difference in CPU temperatures between Kernel 6.4.3 and Kernel 6.5-rc3. Here are my results:

See Bugzilla for the full thread.
Goran: On Tuesday, I asked you to perform bisection. Any update on it?
Anyway, I'm adding this regression to regzbot:
#regzbot introduced: v6.4..v6.5-rc3 https://bugzilla.kernel.org/show_bug.cgi?id=217703
#regzbot title: significant temperature increase on XPS 17 9730
Thanks.

FWIW, I (and likely many others that read this) have no idea what
(distro specifc?) tool you are talking about. But I guess that doesn't
matter. :-D

Okydo, thx for the update.

Bagas, it looks like you forwarded this to the maintainers of
"THERMAL/CPU_COOLING"; I think "THERMAL" would have been the way better
entry in MAINTAINERS, as many (all?) of the former are Linaro employees
and thus primarily care about ARM based devices. That's why I CCed Rafael.

I did some analysis using the 'stress' tool to measure and compare the difference in CPU temperatures between Kernel 6.4.3 and Kernel 6.5-rc3. Here are my results:
One thought: I wonder if there something wrong now or was there
something wrong earlier that was fixed to unleash the full performance
potential of the device. That 100°C there sounds like it's the latter
case, as that's the TJUNCTION temp for that processor. But would be good
to confirm from someone that knows better how hot such processors are
allowed to get these days.

Hi,
I notice a regression report on Bugzilla [1]. Quoting from it:

Goran: On Tuesday, I asked you to perform bisection. Any update on it?
Anyway, I'm adding this regression to regzbot:
#regzbot introduced: v6.4..v6.5-rc3 https://bugzilla.kernel.org/show_bug.cgi?id=217703
#regzbot title: significant temperature increase on XPS 17 9730
Thanks.
