If you want to influence the load-balancer (the only thing that really cares about HT) the best would probably be to add a term to kernel/sched_fair.c:update_cpu_power(). Decrease the power relative to the amount of steal-time, just like freq and time spend on RT tasks. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
