Camera系统 ｜ ConfigureStreams阶段调用
\camx\src\core\hal\camxhal3entry.cpp 下面几步跳转和open类似，不再赘述 \vendor\qcom\proprietary\camx\src\core\ hal\camxhal3.cpp \vendor\qcom\proprietary\camx\src\core\hal\camxhaldevice.cpp 很直观，先获取chi的接口对象 ，大略看一下： \vendor\qcom\proprietary\chi-cdk\core\chiframework\chxextensionmodule.cpp 这个g_chiContextOps ChiEntry方法中的函数指针定义在： \vendor\qcom\proprietary\camx\src\core\chi\camxchi.cpp 接着往下看，进行了很多StreamConfig \proprietary\camx\src\hwl\titan17x\camxtitan17xhwl.cpp \vendor\qcom\proprietary\camx\src\hwl\titan17x

Camera系统 ｜ OpenCamera在camx架构中的调用
\hardware\interfaces\camera\common\1.0\default\CameraModule.cpp 这个调用是在这里做的函数指针映射： \vendor\qcom\proprietary 跟着这段话去查看代码，过程变得无比丝滑 首先，HAL3Module的构造函数中： \vendor\qcom\proprietary\camx\src\core\hal\camxhal3module.cpp \camx\src\core\hal\camxhal3module.cpp 看看chi_extend_open中做了什么 \vendor\qcom\proprietary\chi-cdk\core \core\chiframework\chxextensionmodule.cpp 看上去做了很多设置，没有像tv一样去和V4L2进行交互 接下来，一路返回直至 \vendor\qcom\proprietary \camx\src\core\hal\camxhal3entry.cpp \vendor\qcom\proprietary\camx\src\core\hal\camxhal3.cpp
3K42编辑于 2022-10-05 在系统代码的目录u_sys 及v_sys下都有 QuickstepLauncher.java 那么到底是改u_sys还是改v_sys才能生效？
这种情况在 MTK 平台很常见：厂商会在 vendor/mediatek/proprietary 下提供 定制化代码，同时系统源（packages/apps/Launcher3）也有原生的 AOSP 代码 /作用u_sys/packages/apps/Launcher3/...系统 AOSP 原生 Launcher3 源码基础代码，如果厂商没有覆盖，这份会生效v_sys/vendor/mediatek/proprietary MTK 定制版通常会用 vendor/mediatek/proprietary/... 路径。 方法三：简单经验法 修改 v_sys/vendor/mediatek/proprietary 下的文件几乎总是安全且生效的，因为 MTK 很多自研模块都会覆盖系统源码。 生效优先级： v_sys/vendor/mediatek > u_sys/packages/apps 想改 Launcher 功能/界面/状态栏 → 改 v_sys/vendor/mediatek/proprietary
