产品形态配置

简介

产品形态配置仓。

主要包括产品所属的系统类型,产品名称,对应的device配置,产品的部件列表等。

支持的产品需要在productdefine/common/products/ 目录下有同名的配置文件,编译时找不到会报错。在productdefine/common/device/ 目录下要有产品对应的device的同名配置文件。

产品配置文件中,要指定产品所属的系统类型,使用的device,包含的部件列表等。

配置仓目录结构

productdefine/common
├── base                         # 不同系统类型的最小系统,开发者不用配置,系统提供
│   └── standard_system.json
├── device                       # device配置,配置文件按照device name命名
│   └── hi3516dv300.json
└── products                     # 产品配置,配置文件按照product name命名
    └── Hi3516DV300.json

配置示例

产品配置示例: Hi3516DV300.json

{
  "version": "2.0",                  # 配置文件格式版本
  "product_name": "Hi3516DV300",     # 产品名
  "product_company": "hisilicon",    # 产品厂商名
  "product_device": "hi3516dv300",   # 产品对应的device名,会读取device下的同名配置
  "type": "standard",                # 系统类型,读取base下对应的系统配置
  "inherit": [],                     # 继承的部件列表配置, 可以继承通用的部件列表
  "product_build_path": "",          # product对应的子系统路径
  "parts":{                          # 产品的部件列表
    "common:common":{},
    ......
  }
}

每个产品都要配置对应的系统类型,当前仅支持配置:"standard",,产品会继承对应的系统类型的基础部件列表,从productdefine/common/base/ 目录下读取。

product_build_path是product对应子系统路径,编译时会扫描对应目录下的部件配置。

device配置示例: hi3516dv300.json

需要提供一个产品配置中product_device同名的配置文件,配置device信息和board信息。

{           
  "device_name": "hi3516dv300",   # device名
  "device_company": "hisilicon",  # device厂商名
  "target_os": "ohos",            # 在设备上部署的操作系统名
  "target_cpu": "arm",            # 设备的cpu类型
  "kernel_version": "",
  "device_build_path": ""         # device对应的子系统路径
}

device_build_path是device对应子系统路径,编译时会扫描对应目录下的部件配置。

产品部件类表的生成:

  1. 先加载对应系统类型的最小系统部件列表;
  2. 加载产品对应的device配置的部件列表;
  3. 加载产品继承的通用部件列表;
  4. 加载产品配置的部件列表;
  5. 一个产品包含的所有部件,从上面几个配置中来,同名的后面的会覆盖前面的。

常见问题说明

如何给对应的产品新加一个部件?

在productdefine/common/products/ 目录下,找到对应的产品同名的配置文件,在parts中添加部件信息,格式为:"子系统名:部件名":{}。

如何查看一个指定产品的最终的部件列表?

在编译启动后,编译系统会解析配置文件,生成产品的全部的部件列表,输出为:out/build_configs/{产品名}/preloader/parts.json。
