sched: question on group_capacity when SMT > 2
Peter & Ingo, At the end of update_sg_lb_stats() we have this calculation: sgs->group_capacity = DIV_ROUND_CLOSEST(group->cpu_power, SCHED_LOAD_SCALE); At the sibling level when we have SMT2, cpu_power will be 1178/2 (provided we are not scaling power with freq say) and SCHED_LOAD_SCALE will be 1024, re... 30 Mar 2010 22:57
