1.CPU 频率设置

主要设置CPU的最大和最小频率

• mPerfServiceWrapper.userReg 注册
• mPerfServiceWrapper.userRegScnConfig 参数设定
• mPerfServiceWrapper.userEnable 激活设置
• mPerfServiceWrapper.userDisable 反激活设置
• mPerfServiceWrapper.userUnreg 反注册

示例代码

/**     * CPU mode freq settings     *     * @param minCpuNumber     * @param maxCpuFreq     * @param mode     * @param freqMin     * @param freqMax     * @param coreMin     * @param coreMax     */    public void setCpu(int minCpuNumber, int maxCpuFreq, int mode, int freqMin, int freqMax, int coreMin, int coreMax, boolean screenOffEnable) {        userDisableIfNeed();        if (null != mPerfServiceWrapper) {            mCurPerfHandle = mPerfServiceWrapper.userReg(minCpuNumber, maxCpuFreq);            if (PERFHANDLE_ERROR_CODE != mCurPerfHandle) {                mPerfServiceWrapper.userRegScnConfig(mCurPerfHandle, mPerfServiceWrapper.CMD_SET_VCORE, mode, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE);                mPerfServiceWrapper.userRegScnConfig(mCurPerfHandle, mPerfServiceWrapper.CMD_SET_CPU_CORE_MIN, coreMin, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE);                mPerfServiceWrapper.userRegScnConfig(mCurPerfHandle, mPerfServiceWrapper.CMD_SET_CPU_CORE_MAX, coreMax, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE);                mPerfServiceWrapper.userRegScnConfig(mCurPerfHandle, mPerfServiceWrapper.CMD_SET_CPU_FREQ_MIN, freqMin, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE);                mPerfServiceWrapper.userRegScnConfig(mCurPerfHandle, mPerfServiceWrapper.CMD_SET_CPU_FREQ_MAX, freqMax, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE);                if (screenOffEnable) {                    mPerfServiceWrapper.userRegScnConfig(mCurPerfHandle, mPerfServiceWrapper.CMD_SET_SCREEN_OFF_STATE, mPerfServiceWrapper.SCREEN_OFF_ENABLE, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE, PARAM_DEFAULT_VALUE);                }                mPerfServiceWrapper.userEnable(mCurPerfHandle);                Log.d(TAG, "setCpu minCpuNumber = " + minCpuNumber + ", maxCpuFreq = " + maxCpuFreq + ", mode = " + mode + ", freqMin = " + freqMin + ", freqMax = " + freqMax + ", coreMin = " + coreMin + ", coreMax = " + coreMax + ", mCurPerfHandle = " + mCurPerfHandle);            }        }    }    /**     * 退出注册     */    public void userUnreg() {        if (mCurPerfHandle != PERFHANDLE_ERROR_CODE) {            mPerfServiceWrapper.userDisable(mCurPerfHandle);            mPerfServiceWrapper.userUnreg(mCurPerfHandle);            Log.d(TAG, "userUnreg  mCurPerfHandle = " + mCurPerfHandle);        }    }
