认为有人在使用

CameraService::connect 失败

StagefrightRecorder 这个在存储的时候做

EnumDevParam
这分辨率不支持 ？
csi 和 uvc

应该为csi的

后置摄像头

uvc 和 csi的查询接口不一样

还有一个基类 V4l2CapDeviceBase

    CAMERA_HAL_ERR_RET CameraHal::Init()
    {
        CAMERA_HAL_LOG_FUNC;
        CAMERA_HAL_ERR_RET ret = CAMERA_HAL_ERR_NONE;
        mCameraReady == true;

        if ((ret = AolLocForInterBuf())<0)
            return ret;
        if ((ret = InitCameraHalParam()) < 0)
            return ret;
        if (mPPDeviceNeed == true && mPPDevice == NULL)
            return CAMERA_HAL_ERR_PP_NULL;
        if ((ret = CameraMiscInit()) < 0)
            return ret;

        return ret;
    }
   
    初始化得时候会枚举设备参数
   
    基类实现了捕获设备的接口
   
    mxc_v4l_open 打开

如果是打开失败 out/target/product/imx51_bbg/system/lib/libcamera.so

mxc_v4l2_probe match后做了什么？

跟谁match的？

v4l2_int_device_try_attach_all

int v4l2_int_device_register(struct v4l2_int_device *d)
{
 if (d->type == v4l2_int_type_slave)
  sort(d->u.slave->ioctls, d->u.slave->num_ioctls,
       sizeof(struct v4l2_int_ioctl_desc),
       &ioctl_sort_cmp, NULL);
 mutex_lock(&mutex);
 list_add(&d->head, &int_list);
 v4l2_int_device_try_attach_all();
 mutex_unlock(&mutex);

 return 0;
}

ioctl_sort_cmp 比较大小

struct v4l2_int_master {
 int (*attach)(struct v4l2_int_device *slave);
 void (*detach)(struct v4l2_int_device *slave);
};

struct v4l2_int_device {
 /* Don't touch head. */
 struct list_head head;

 struct module *module;

 char name[V4L2NAMESIZE];

 enum v4l2_int_type type;
 union {
  struct v4l2_int_master *master;
  struct v4l2_int_slave *slave;
 } u;

 void *priv;
};

主从设备

每个slave 有自己的ioctl 描述

struct v4l2_int_slave {
 /* Don't touch master. */
 struct v4l2_int_device *master;

 char attach_to[V4L2NAMESIZE];

 int num_ioctls;
 struct v4l2_int_ioctl_desc *ioctls;
};

主设备调用从设备的方法

slave attach 有什么问题

static int mxc_v4l2_master_attach(struct v4l2_int_device *slave)

实际上这个函数就没有走

In MVC: init_camera_struct
m->type != v4l2_int_type_master 0  m->name mxc_v4l2_cap
s->type != v4l2_int_type_slave  1  s->u.slave->master -21444612720x
zhw m->name mxc_v4l2_cap ,s->u.slave->attach_to .?

现在可能是slave没有注册

现在看一下slave 注册有什么问题

OV3640 根本没有注册

int __init
i2c_register_board_info(int busnum,
 struct i2c_board_info const *info, unsigned len)
{
 int status;

 down_write(&__i2c_board_lock);

 /* dynamic bus numbers will be assigned after the last static one */
 if (busnum >= __i2c_first_dynamic_bus_num)
  __i2c_first_dynamic_bus_num = busnum + 1;

 for (status = 0; len; len--, info++) {
  struct i2c_devinfo *devinfo;

  devinfo = kzalloc(sizeof(*devinfo), GFP_KERNEL);
  if (!devinfo) {
   pr_debug("i2c-core: can't register boardinfo!\n");
   status = -ENOMEM;
   break;
  }

  devinfo->busnum = busnum;
  devinfo->board_info = *info;
  list_add_tail(&devinfo->list, &__i2c_board_list);
 }

 up_write(&__i2c_board_lock);

 return status;
}

注册板I2C信息

现在的问题是怎么来读这个数组呢？

先看注册的驱动对不对

寄存器写失败
