Hi All, I am working on research related to Power management and control for single and multiprocessors. I have come across the PowerTop application and found that is shows all information about the CPU c & p states and thermal states but while going through the old mailing list i found one mail saying that it is only good for showing the power consumption while CPU is in idle state. I want to get all CPU power information for different applications and kernel processes running into system (with load). I have also gone through the PowerTop application code and found it is reading from the various kernel files all the information. As per my understaning this information is written by the ACPI HW/SW module. Previously, I read through ACPI specification but not sure how to call those APIs and after going through PowerTop Application i found my understanding was wrong as the ACPI is already part of most Linux kernels and so the application simply should read the power state related information from kernel files. I am not able to figure out few things in the code, also not sure if my approach is correct and i can enhance PowerTop application to achieve my goal, i guess people who have developed the application can give me some idea if i can enhance the app and it would be a great help...
I am using an environment with Intel Dual Core Tm processor and Ubuntu platform. Thanks and Regards, - Nisha
