Bumping this as I discovered this issue on 6.12 stable branch also. The reapplication seems inevitable. I shall get back to you with these details also.
Yes, please, because I have another reason to restore the reverted commit.
Sergey, did you see a performance regression from 85975daeaa4d ("cpuidle: menu: Avoid discarding useful information") on any platforms other than the Jasper Lake it was reported for?
Let me try to dig it up. I think I saw regressions on a number of devices:
--- cpu family : 6 model : 122 model name : Intel(R) Pentium(R) Silver N5000 CPU @ 1.10GHz --- cpu family : 6 model : 122 model name : Intel(R) Celeron(R) N4100 CPU @ 1.10GHz --- cpu family : 6 model : 156 model name : Intel(R) Celeron(R) N4500 @ 1.10GHz --- cpu family : 6 model : 156 model name : Intel(R) Celeron(R) N4500 @ 1.10GHz --- cpu family : 6 model : 156 model name : Intel(R) Pentium(R) Silver N6000 @ 1.10GHz
I guess family 6/model 122 is not Jasper Lake?
I also saw some where the patch in question seemed to improve the metrics, but regressions are more important, so the revert simply put all of the boards back to the previous state.
