[Query-CPUIdle]: Not much activity in C0 state

[Viresh Kumar]

Hi Guys,

I was trying to run following on my thinkpad:

watch -n1 cat /sys/devices/system/cpu/cpu*/cpuidle/state*/usage

I can see lots of activities on State 1-4, but not much on state 0..
I thought we should enter this state as soon as we come out to
non-idle state.. And so this count must be changing quite rapidly.

Is this a bug?
