Hi
I have tested this way of change cpufreq (/sys/devices/system/cpu/cpu[x]/cpufreq/scaling_setspeed),and it works.
By the way, there are only three available frequencies(1.1G 800M 600M),and CPU only enter ilde mode. However,I hope cpu can step into Deeper sleep(C4) even Deep Power Down(C6).
so how can I enable this feature?
I suspect that your system WILL go into C4.
If you are not sure, you can run the powertop tool, this will tell you exactly
which C and P states you are using, and how much.
