Hi Qais Thanks for the patient explanation.:) And I have some other concerns.

Maybe the implementation of this function, I have not thought of a good solution. (1)how to define the inversion, if the cpu has two cluster(little/big),it is easy, but still need mark which is the big cpu... (2)because the mainline kernel should be common, if the cpu has three or more clusters, maybe the mid cpus also would be inversion; (3)what time update the cpu inversion state, if we judge the cpu inversion whenever the thermal pressure changed, could we receive the complexity? because may we should traverse all possible cpu.
Thanks!
