I had seen the above logic. My aim is not to display all the P states. Am fine with top 4 (after sorting), how it currently does, and thus didn't suggest to change this in my patch. Though in some of the ARM boards the number of P states can be less than 4. Hence the display won't be nice for such boards. But, actually its the cpuidle states (C states), which bothers me more than the P states. The problem is that on some of the ARM boards the number of C states can be as many as 9 ! And different ARM SoC have different number of these C and P states. So, its not practical to have them hardcoded for each board! Hence, we need a way to dynamically find out the number of C and P states, and display accordingly. And the same code should ideally work on x86, ARM and any other architecture that may want to use powertop. > On the other hand side there already is sorting for most relevant/mostly > used frequencies and only these are cut out.

The goal here is to have the same code function on x86 and various ARM SoCs - which have different levels of these C and P states. Thanks!
