Just a note: Yes, we are scaling the load tracking of each task to compensate for frequency scaling. I think that is all fine. Later we will have to feed the current frequency into the energy model as well to figure out if putting more tasks on a cpu will/should cause the frequency to increase or not. We don't need it for now and don't need to add it in the commit message. It is just a reminder that we may actually want to use arch_scale_freq_capacity() combined with cpu_capacity to provide this input to the energy model later. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
