(Before starting, i want to say i am not the developer of the patch, i am just an end user of a distribution kernel, which has just faced some problem, i don't even know if kernel team accepts patch requests from non dev, and thi mail is mostly shot in dark)
Respected Sir/s/Ma'am/s I want to request that patch https://lore.kernel.org/all/20230627062442.54008-1-mika.westerberg@linux.int... be accepted in to the stable 6.1 branch, it is already present in the current branch, and i request for it to be backported. This fixes some Intel CPUs (according to other users claims, ranging back to 6th gen for some) not going to deeper c states with kernels 5.16+, and was fixed by this patch in 6.4.4+, since many institutions, and distributions use 6.1, it would be great if this is included (from what i understand from requirements (https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html) i guess it fits all)
I was facing this issue for roughly a year, and then reported in debian(my distribution) forums, and we found nothing earlier (https://forums.debian.net/viewtopic.php?t=154875), then i posted on some other forums, and then i was asked to check if there was an active bug linux kernel tracker at that time, and i could not find one, so i decided to raise an issue (https://bugzilla.kernel.org/show_bug.cgi?id=217616), but just a few days prior to me posting someone had submiteed the patch, that i did not know of, since then i am using the newest kernel(in 6.4 branch) and am not facing issues.
I apologize for all the foolishness of mine, and just making an humble request.
Thank You
