Subject: Re: [PATCH 2/2] lib/sort: Optimize heapsort with double-pop variation

Message-ID: <70674dc7-5586-4183-8953-8095567e73df@gmail.com> (raw)

Hello,
it appears that this patch has caused suspend-to-idle regression:
https://gitlab.freedesktop.org/drm/amd/-/issues/3436
In brief, my laptop fails to suspend completely with the following error
in the log:
Jun 18 12:42:20 kernel: amd_pmc AMDI0005:00: Last suspend didn't reach
deepest state
Power consumption remains high enough that my battery has already
unexpectedly drained twice before I noticed something was off.
I am not entirely sure how changes to sorting function can influence
suspend, but it is what it is. 6.9.5 as shipped by Fedora 40 exhibits
the issue, 6.9.5 as shipped by Fedora with the patch reverted does not.
Best regards,
Juliam
