I was thinking about using ACPI concept in embedded systems to manage cpu and device power consumption. I know that there is lack of hardware ACPI supports, but as far as I understand, the core of ACPI is various ACPI tables which describe hardware device resources and define control methods. Just one very simple example, if I have one device or periphery attached on a bus that can be operated in different power saving states, maybe I could describe this device in the DSDT so that the OS could configure and govern it at runtime. Besides, I think there are also many embedded processors which supports DVFS. As I would like to try this on a FPGA based development platform, I could add some additional hardware supports by myself if needed. These are only some thoughts, but I am not sure if it is feasible. I would be very grateful if you could give me some advice. Thanks in advance.
