System -> Debug (Keep Out) -> View CPU stats Will now show the current cpufreq scaling governor, minimum, current and maximum cpufreq scaling frequency for each CPU. This may be genric for Android kernel based devices but is only enabled for iBasso Devices. Other maintainers may choose do adopt this. Change-Id: I53e212f8707bf2abaa557e297293fb559ac37058
