Saravana and David know this and we discussed at LPC. uclamp hints are limits and should not be summed. > [2]: https://android.googlesource.com/kernel/gs/+/refs/heads/android-gs-raviole-5.10-android12-d1/drivers/soc/google/vh/kernel/sched/fair.c#510 I think I clarified several times so far that this is not related to uclamp. Could you please refrain from referring to it again in the future? This is misleading and neither helps your cause nor its cause. The fact that you're relating to it makes me very worried as both links demonstrate lack of understanding/confusion of what uclamp is supposed to be. Again, this solution is not acceptable and you're moving things in the wrong direction. We don't want to redesign what uclamp means, but fix some corner cases. And you're doing the former not the latter.
