tools/power turbostat: dump CONFIG_TDP
Config TDP is a feature that allows parts to be configured for different thermal limits after they have left the factory. This can have an effect on the operation of the part, particularly in determiniing... Max Non-turbo Ratio Turbo Activation Ratio Signed-off-by: Len Brown <len.brown@intel.com>
