Hi Valentin,
I would like to check whether I have understood what you mentioned. Based on the following Hikey Big cluster core, https://android.googlesource.com/kernel/hikey-linaro/+/android-hikey-linaro-...
50 - 'Active' idle state 50 - WFI 15 - cpu-nap 0 - cpu-sleep 0 - cluster-sleep
Would the above order be correct?
Yes.
Also, what exactly do the idle-cost-data values mean? Do they refer to the cost of maintaining the core/cluster at that idle state, or the cost to put/exit the core/cluster into the idle state?
For upper array, they refer to the cost of maintaining the core at that idle state. There have another array data to maintain cluster level data: https://android.googlesource.com/kernel/hikey-linaro/+/android-hikey-linaro-...
Thanks, Leo Yan
