But it seems no more progress/solution relate to this problem until now. I also checked the example code:"L3 Forwarding with Power Management Sample Application" in newest dpdk version (17.02) , no update yet. Is it true that, newer cpufreq driver p-state only support two control-mode: "performance" and "powersave", and we can't do any more about cpu working frequency control, for power-saving? Thanks for your help. Best Regards, Peng
