Hi, I am a third year PhD student working on power management in storage systems, under the Linux platform. We are exploring CPU DVFS, and also idle CPU C states. We figured out that the scheduling of CPU frequencies is exported to user level with the "userspace" governor. However, it seems the multiple idle C states are only scheduled in the kernel space (governors like "menu" and "ladder"). We wonder whether there is any existing kernel module or existing kernel patch that can export the various idle CPU C states to the user level for user's control as well. If you could guide us to such code/patch, or if you have plan to do so, we'd be more than happy to help you testing the code for various idle CPU C states in the user level. Thanks for your time. Appreciated it!
