Hey All. In digging through some pieces around CPU_IDLE I noticed that NO_HZ_IDLE is explicitly disabled on x86_64 but not on all other architectures. Doing a "git log --follow configs/fedora/generic/x86/x86_64/CONFIG_NO_HZ_IDLE" it goes all the way back to 2016 when we changed the way the configs were handled. The upstream kernel's opinion [1] on it is "Most of the time you want to say Y here." so I'm wondering if there's a reason why we're difference on x86_64 or is it just lost in the winds of time? Peter PS was digging around CPU_IDLE_GOV_TEO for those curious. [1] https://cateee.net/lkddb/web-lkddb/NO_HZ_IDLE.html
