Whats running in the system? If the system is pretty much idle, then the lowest P-state for that CPU is justified. Race-to-idle can happen if you have short running workloads that can finish faster if run at max freq. If there is no significant work, then the freq is at the lowest and you should expect to see lowest sleep state (C3 or C4) being used 99% of the time. --Vaidy _______________________________________________ Discuss mailing list [email protected] http://mail.lesswatts.org/mailman/listinfo/discuss
