（1）Hal流程的代码

（A）updateAEInfo2ISP（ae_mgr.cpp）

//vendor/mediatek/proprietary/hardware/mtkcam/aaa/source

MRESULT AeMgr::updateAEInfo2ISP(AE_STATE_T eNewAEState, MUINT32 u4ISPGain)
{
		//...
		switch (eNewAEState)
    {
    		case AE_SENSOR_PER_FRAME_STATE :
            rAEInfo2ISP.u4Eposuretime = m_u4UpdateShutterValue;
            rAEInfo2ISP.u4AfeGain = m_u4UpdateGainValue;

            if (u4ISPGain != 0x00)
            {
                rAEInfo2ISP.u4IspGain = u4ISPGain;
                AE_LOG_IF(m_3ALogEnable, "[%s()] Smooth ISP Gain:%d avgY:%d\n", __FUNCTION__, rAEInfo2ISP.u4IspGain, m_pIAeAlgo->getBrightnessAverageValue());
            }
            else
            {
                rAEInfo2ISP.u4IspGain = 1024;
                AE_LOG("[%s()] No Smooth ISP Gain:%d avgY:%d\n", __FUNCTION__, rAEInfo2ISP.u4IspGain, m_pIAeAlgo->getBrightnessAverageValue());
            }

            u4FinalGain = (rAEInfo2ISP.u4AfeGain * rAEInfo2ISP.u4IspGain) >> 10;
            rAEInfo2ISP.u4RealISOValue = (u4PreviewBaseISO * u4FinalGain + (u4PreviewBaseGain - 1)) / u4PreviewBaseGain;
            u2FrameRate = m_u4UpdateFrameRate_x10;
            rAEInfo2ISP.bAEScenarioChange = MTRUE; //AE2AF info, avoid scenario(index) change mis-trigger AF
            break;
    }

	//...
	AE_LOG("[%s()] State:%d eAEstate:%d VDNum:%d Exp/Afe/Isp/ISO:%d/%d/%d/%d CurrentidxF:%d DisableOBC:%d FrameRate:%6.3f FrameDuration:%lld Flare offset/gain:%d/%d ExpRatio:%d\n",
        __FUNCTION__, eNewAEState, m_eAEState, m_i4WaitVDNum,
        rAEInfo2ISP.u4Eposuretime, rAEInfo2ISP.u4AfeGain, rAEInfo2ISP.u4IspGain, rAEInfo2ISP.u4RealISOValue, rAEInfo2ISP.u4AEidxCurrentF, rAEInfo2ISP.bDisableOBC,
        u2FrameRate, (long long)m_rSensorCurrentInfo.u8FrameDuration, rAEInfo2ISP.i2FlareOffset, i2FlareGain, rAEInfo2ISP.u4EISExpRatio);
}

（B）configure（HalSensor.control.cpp）

//vendor/mediatek/proprietary/hardware/mtkcam/drv/src/sensor/common

MBOOL HalSensor::configure(
    MUINT const         uCountOfParam,
    ConfigParam const  *pArrayOfParam
)
{
		//...
		if (pArrayOfParam->HDRMode != 0) { // vHDR mode
        //...
   		 } else { // normal mode
        	MUINT exposureTime = pArrayOfParam->exposureTime;
        	MUINT gain = pArrayOfParam->gain;
        	if (exposureTime > 0 && gain > 0) {
            	ret = pSensorDrv->sendCommand(sensorIdx, CMD_SENSOR_SET_SENSOR_EXP_TIME, (MUINTPTR)&(exposureTime));
            	ret = pSensorDrv->sendCommand(sensorIdx, CMD_SENSOR_SET_SENSOR_GAIN, (MUINTPTR)&(gain));
        	}
    	}
}

（C）sendCommand（imgsensor_drv.cpp）

MINT32 ImgSensorDrv::sendCommand(
        IMGSENSOR_SENSOR_IDX sensorIdx,
        MUINT32 cmd,
        MUINTPTR arg1,
        MUINTPTR arg2,
        MUINTPTR arg3
)
{
		switch (cmd) {
				case CMD_SENSOR_SET_SENSOR_EXP_TIME:
        			u8temp = *parg1;/*64bit extend */
        			FeatureId = SENSOR_FEATURE_SET_ESHUTTER;
       				LineTimeInus = m_LineTimeInus[sensorIdx];
        			FeaturePara[0] = ((1000 * (u8temp)) / LineTimeInus);
        			if(FeaturePara[0] == 0) {   // avoid the line number to zero
           	 			LOG_MSG("[CMD_SENSOR_SET_EXP_TIME] m_LineTime = %llu %d", (long long)FeaturePara[0], LineTimeInus);
            			FeaturePara[0] = 1;
       				}
        			FeatureParaLen = sizeof(MUINT64);
        			pFeaturePara = (MUINT8*)FeaturePara;

        			LOG_MSG("[CMD_SENSOR_SET_EXP_TIME] FeaturePara[0] = %llu, FeaturePara[1] = %llu, FeaturePara[2] = %llu, FeaturePara[3] = %llu", FeaturePara[0], FeaturePara[1], FeaturePara[2], FeaturePara[3]);
        			break;

				case CMD_SENSOR_SET_SENSOR_GAIN:
       				FeatureId = SENSOR_FEATURE_SET_GAIN;
			        FeaturePara[0] = *parg1; //from 10b to 6b base
        			FeaturePara[0] >>= 4;
        			FeatureParaLen = sizeof(MUINT64);
        			pFeaturePara =  (MUINT8*)FeaturePara;
        			
        			LOG_MSG("[CMD_SENSOR_SET_SENSOR_GAIN] FeaturePara[0] = %llu, FeaturePara[1] = %llu, FeaturePara[2] = %llu, FeaturePara[3] = %llu", FeaturePara[0], FeaturePara[1], FeaturePara[2], FeaturePara[3]);
        			break;
		}

		//...
		err= featureControl(sensorIdx, FeatureId,  (MUINT8*)pFeaturePara,(MUINT32*)&FeatureParaLen);
}

ImgSensorDrv::featureControl(
      IMGSENSOR_SENSOR_IDX sensorIdx,
      ACDK_SENSOR_FEATURE_ENUM FeatureId,
      MUINT8 *pFeaturePara,
      MUINT32 *pFeatureParaLen
  )
  {
      ACDK_SENSOR_FEATURECONTROL_STRUCT featureCtrl;
  
      if (m_fdSensor == -1) {
          LOG_ERR("[sendCommand]m_fdSensor fail, sendCommand must be called after init()!");
          return SENSOR_UNKNOWN_ERROR;
      }
  
      if (pFeaturePara == NULL || pFeatureParaLen == NULL) {
          return SENSOR_INVALID_PARA;
      }
  
      featureCtrl.InvokeCamera = sensorIdx;
      featureCtrl.FeatureId = FeatureId;
      featureCtrl.pFeaturePara = pFeaturePara;
      featureCtrl.pFeatureParaLen = pFeatureParaLen;
  
      if (ioctl(m_fdSensor, KDIMGSENSORIOC_X_FEATURECONCTROL , &featureCtrl) < 0) {
          LOG_ERR("[featureControl] Err-ctrlCode (%s)", strerror(errno));
          return -errno;
      }
  
      return SENSOR_NO_ERROR;
  }

通过featureControl最终调用到ioctl控制函数，进而调用到Camera Drv驱动。

（2）Drv流程的代码

static struct SENSOR_FUNCTION_STRUCT sensor_func = {
	open,
	get_info,
	get_resolution,
	feature_control,
	control,
	close
};

UINT32 XXXX_MIPI_RAW_SensorInit(struct SENSOR_FUNCTION_STRUCT **pfFunc)
{
	/* Check Sensor status here */
	if (pfFunc != NULL)
		*pfFunc = &sensor_func;
	return ERROR_NONE;
}

static kal_uint32 feature_control(MSDK_SENSOR_FEATURE_ENUM feature_id,
	UINT8 *feature_para, UINT32 *feature_para_len)
{
	//...
	LOG_INF("feature_id = %d\n", feature_id);
	switch (feature_id) {
		case SENSOR_FEATURE_SET_ESHUTTER:
			set_shutter(*feature_data);
			break;
		case SENSOR_FEATURE_SET_GAIN:
			set_gain((UINT16)*feature_data);
			break;
	}
	//...
}

而set_gain和set_shutter函数如下：

static kal_uint16 gain2reg(kal_uint16 gain)
{
	kal_uint16 reg_gain = gain << 4;

	reg_gain = (reg_gain < SENSOR_BASE_GAIN) ? SENSOR_BASE_GAIN : reg_gain;
	reg_gain = (reg_gain > SENSOR_MAX_GAIN) ? SENSOR_MAX_GAIN : reg_gain;

	return reg_gain;
}

static kal_uint16 set_gain(kal_uint16 gain)
{
	kal_uint32 reg_gain = 0;
	reg_gain = gain2reg(gain);
	
	write_cmos_sensor(0x0204, reg_gain & 0xffff);
	return gain;
}

static void set_shutter(kal_uint32 shutter)
{
	//...
	shutter = (shutter < imgsensor_info.min_shutter) ? imgsensor_info.min_shutter : shutter;
	shutter = (shutter > (imgsensor_info.max_frame_length - imgsensor_info.margin)) ?
		(imgsensor_info.max_frame_length - imgsensor_info.margin) : shutter;

	write_cmos_sensor(0x0202, shutter & 0xffff);
	
	LOG_INF("shutter = %d, framelength = %d\n",
		shutter, imgsensor.frame_length);
}

最终通过Drv驱动设置到寄存器中。
