Upstream fixup fa3fa55de0d ("cpuidle: governors: menu: Avoid using invalid recent intervals data") doesn't address the problems we are observing. Revert seems to be bringing performance metrics back to pre-regression levels.
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?
