bool AppManager::requestArmSetClock

(

uint32_t

requested_cpu_frequency

)

provides an interface for apps to request cpu freq change note: this is only a request. the actual frequency will vary based on the allowed freq range and current cpu temp

Parameters

requested_cpu_frequency

Returns

true

false
