From: Ingo Molnar Date: Mon, 9 Jul 2007 16:52:01 +0000 (+0200) Subject: sched: more agressive idle balancing X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9c4801cebc2add1fe514bc8eb201b16372eee11a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git sched: more agressive idle balancing the Linux scheduler is starving a number of workloads. So default to more agressive idle-balancing. This hurts lmbench context-switching numbers (which was the main reason we sucked at idle-balancing for such a long time) but the lmbench numbers are fine once the system is minimally utilized.
