Any details would be much appreciated. How do the idle state usages differ with and without "cpuidle: menu: Avoid discarding useful information"? What do the idle states look like in your platform?
Sure, I can run tests.
Would it be possible to check if the mainline has this issue? That is, compare the benchmark results on unmodified 6.17 (say) and on 6.17 with commit 85975daeaa4 reverted?
I don't think mainline kernel can run on those devices (due to a bunch of downstream patches). Best bet is 6.12, I guess.
Depending on what Rafael is expecting here you might just get away with copying menu.c from mainline, the interactions to other subsystems are limited fortunately.
Yeah, that'd be sufficiently close.
