MTK Camera 开机启动流程（转载）

一、MTK平台Camera框架

MTK平台的Camera的架构见下图，

MTK Camera 开机启动流程（转载）-LMLPHP

这里主要介绍kernel部分和HAL层部分。

1、Kernel 部分主要有两块:

1.1、image sensordriver,负责具体型号的 sensor 的 id 检测,上电，以及在preview、capture、初始化、3A等等功能设定时的寄存器配置。

1.2、isp driver，通过DMA将sensor数据流上传。

2、HAL层部分主要有三部分组成：

2.1、imageio，主要负责数据buffer上传的pipe。

2.2、drv，包含imgsensor和isp的hal层控制。

2.3、feature io，包含各种3A等性能配置。

二、Camera打开流程分析

Camera开启流程图如下：

MTK Camera 开机启动流程（转载）-LMLPHP

主要发生在两个时间点：

1、开机时：camera完成了sensor框架初始化，id检测并匹配sensor，以及上下电操作。

2、打开Camera应用时：camera会有上电，完成sensor的寄存器初始化配置，向上层传递基本参数和配置信息，以及preview和capture模式循环。

1、开机初始化过程

由于一开始不知道上电camera初始化从哪开始，我们可以借助抓取的mtk mobile log去分析。先看hal层log开始处：

（2.2）g_invokeSocketIdx，drvIdx解释

上层传下来的 id 参数解析成两部分 g_invokeSocketIdx 区分目前正在匹配的是 main 还是sub，drvIdx 是 sensor 列表的序列号 。

（2.3）获取指定sensor的func函数，例如ov5670的func，pSensorList[drvIdx[i]].SensorInit(&g_pInvokeSensorFunc[i]);

调用的函数是OV5670_MIPI_RAW_SensorInit()。

  1. #if defined(OV5670_MIPI_RAW)
  2. {OV5670_SENSOR_ID, SENSOR_DRVNAME_OV5670_MIPI_RAW, OV5670_MIPI_RAW_SensorInit},
  3. #endif

===>mediatek/custom/common/kernel/imgsensor/ov5670_mipi_raw/ov5670mipiraw_Sensor.c

  1. SENSOR_FUNCTION_STRUCT  SensorFuncOV5670=
  2. {
  3. OV5670Open,
  4. OV5670GetInfo,
  5. OV5670GetResolution,
  6. OV5670FeatureControl,
  7. OV5670Control,
  8. OV5670Close
  9. };
  10. UINT32 OV5670_MIPI_RAW_SensorInit(PSENSOR_FUNCTION_STRUCT *pfFunc)//---调用此函数
  11. {
  12. if (pfFunc!=NULL)
  13. *pfFunc=&SensorFuncOV5670;
  14. return ERROR_NONE;
  15. }

5670的sensorinit实现，主要是未了pfFunc这个函数指针的结构体指针赋值，这样我们就实现了驱动代码的分离，hal层只需要调用sensorlist.c这样一个虚拟设备的驱动，就可以和具体的Sensor Driver驱动通信。这样的做法与platform driver的设计思想差不多，在tp，lcm等驱动中也有体现。

一、MTK平台Camera框架

MTK平台的Camera的架构见下图，

MTK Camera 开机启动流程（转载）-LMLPHP

这里主要介绍kernel部分和HAL层部分。

1、Kernel 部分主要有两块:

1.1、image sensordriver,负责具体型号的 sensor 的 id 检测,上电，以及在preview、capture、初始化、3A等等功能设定时的寄存器配置。

1.2、isp driver，通过DMA将sensor数据流上传。

2、HAL层部分主要有三部分组成：

2.1、imageio，主要负责数据buffer上传的pipe。

2.2、drv，包含imgsensor和isp的hal层控制。

2.3、feature io，包含各种3A等性能配置。

二、Camera打开流程分析

Camera开启流程图如下：

MTK Camera 开机启动流程（转载）-LMLPHP

主要发生在两个时间点：

1、开机时：camera完成了sensor框架初始化，id检测并匹配sensor，以及上下电操作。

2、打开Camera应用时：camera会有上电，完成sensor的寄存器初始化配置，向上层传递基本参数和配置信息，以及preview和capture模式循环。

1、开机初始化过程

由于一开始不知道上电camera初始化从哪开始，我们可以借助抓取的mtk mobile log去分析。先看hal层log开始处：

5670的sensorinit实现，主要是未了pfFunc这个函数指针的结构体指针赋值，这样我们就实现了驱动代码的分离，hal层只需要调用sensorlist.c这样一个虚拟设备的驱动，就可以和具体的Sensor Driver驱动通信。这样的做法与platform driver的设计思想差不多，在tp，lcm等驱动中也有体现。

以上是ov5670获取ID的函数。

三、开机打开sensor总结

    • HAL层运行Search sensor这个线程
    • HAL层遍历sensorlist列表并挂载HAL层性能3A等一些参数获取的接口
    • HAL层下达setDriver的cmd，并下传正在遍历的sensorlist列表中的ID
    • Driver层根据这个ID，挂载Driver层sensorlist中对应的Sensorlist中对应的Sensor和具体Sensor底层操作接口
    • HAL层对正确遍历的sensor下达check ID的指令
    • Driver层为对应sensor上电，通过I2C读取预存在寄存器中的sensor id
    • 比较读取结果，不匹配，return error，继续遍历
    • 匹配，HAL层下达其他指令收集sensor信息
    • sensor下电
