From b312c991e9055198e96571feaf73df26e647df56 Mon Sep 17 00:00:00 2001 From: Todd Kjos Date: Fri, 11 Mar 2016 16:44:16 -0800 Subject: sched/fair: add tunable to set initial task load The choice of initial task load upon fork has a large influence on CPU and OPP selection when scheduler-driven DVFS is in use. Make this tuneable by adding a new sysctl "sched_initial_task_util". If the sched governor is not used, the default remains at SCHED_LOAD_SCALE Otherwise, the value from the sysctl is used. This defaults to 0.
