android 对接的方式。 4 | 5 | 在 demo 中主要演示了划线的功能，对比 chromium 中 canvas 的划线，这里演示的方法应该是 canvas 划线的性能上限，可以用来评估 chromium 渲染引入的性能损失情况。 6 | 7 | - [gapid_opengles_trace.gfxtrace](./gapid_opengles_trace.gfxtrace) 是通过

demo_apk 2 | 3 | `demo_apk` 可以构建出一名为`DemoApk.apk`的Android应用，它和普通的Android应用最大的不同就是构建方式。一般的Android开发者使用AndroidStudio等IDE来构建Android应用，在chromium中不使用这些IDE而使用gn。 4 | 5 | chromium提供了一套gn配置用来打包各种Android组件，包括 apk,aar,jar 等。主要的脚本位于`//build/config/android/`目录下。可以重点查看以下两个文件： 6 | 7 | ```gn 8 | //build/config/android/config.gni 9 | //build/config/android/rules.gni 10 | ``` 11 | 12 | ## demo_apk 构成 13 | 14 | demo_apk 由以下几部分组成： 15 | 16 | 1. `AndroidManifest.xml`：Android应用的描述文件，包括权限定义，icon等； 17 | 2. `res`: Android应用的资源文件，包括UI布局，图片，字符串等； 18 | 3. `src`: 源代码文件； 19 | 4. `cpp`: 保存 JNI 相关代码； 20 | 21 | ## JNI 22 | 23 | gn提供了从java代码生成JNI/C++头文件的脚本，具体信息参考`base/android/jni_generator/README.md`。 -------------------------------------------------------------------------------- /demo_android/demo_apk/cpp/demo_apk_library_loader.cc: -------------------------------------------------------------------------------- 1 | #include "base/android/jni_android.h" 2 | // #include "content/public/app/content_jni_onload.h" 3 | // #include "content/public/app/content_main.h" 4 | 5 | #include "base/android/base_jni_onload.h" 6 | #include "base/logging.h" 7 | 8 | //#include "demo/demo_shell/app/demo_shell_content_main_delegate.h" 9 | 10 | JNI_EXPORT jint JNI_OnLoad(JavaVM* vm, void* reserved) { 11 | DLOG(INFO) << "[demo_apk] JNI_OnLoad start"; 12 | // 这个初始化是必要的，因为LibraryLoader依赖它，大量的base::android::*都依赖它 13 | // 它其实就是将vm保存为了内部的全局变量 14 | base::android::InitVM(vm); 15 | // 下面这个初始化在这个程序中不是必须的，但是推荐加上，主要是初始化了ClassLoader 16 | if (!base::android::OnJNIOnLoadInit()) 17 | return false; 18 | 19 | // 我们没有使用（crazy linker）动态注册JNI函数的方式，所以这里不需要以下代码 20 | // if (!RegisterMainDexNatives(env) || !RegisterNonMainDexNatives(env)) { 21 | // return -1; 22 | // } 23 | 24 | DLOG(INFO) << "[demo_apk] JNI_OnLoad finished"; 25 | return JNI_VERSION_1_4; 26 | } 27 | -------------------------------------------------------------------------------- /demo_android/demo_apk/cpp/demo_foo.cc: -------------------------------------------------------------------------------- 1 | #include "demo/demo_android/demo_apk/cpp/demo_foo.h" 2 | 3 | #include "base/android/jni_android.h" 4 | #include "base/android/jni_string.h" 5 | #include "base/android/scoped_java_ref.h" 6 | #include "base/bind.h" 7 | #include "base/lazy_instance.h" 8 | 9 | #include "demo/demo_android/demo_apk/demo_apk_jni_headers/DemoFoo_jni.h" 10 | 11 | namespace demo_jni { 12 | 13 | base::android::ScopedJavaGlobalRef j_demo_foo; 14 | 15 | void DemoFoo::HelloDemoFoo(JNIEnv* env, const base::android::JavaParamRef& who) { 16 | LOG(INFO)<<"[demo_foo] DemoFoo::HelloDemoFoo: Hello," << base::android::ConvertJavaStringToUTF8(env, who); 17 | } 18 | 19 | static jlong JNI_DemoFoo_Init(JNIEnv* env, const base::android::JavaParamRef& caller) { 20 | DLOG(INFO) << "[demo_apk]================ JNI_DemoFoo_Init"; 21 | j_demo_foo.Reset(caller); 22 | return reinterpret_cast(new DemoFoo()); 23 | } 24 | 25 | static void JNI_DemoFoo_Hello(JNIEnv* env, const base::android::JavaParamRef& who) { 26 | LOG(INFO)<<"[demo_foo] JNI_DemoFoo_Hello: Hello,"< 5 | 6 | #include "base/android/jni_android.h" 7 | #include "base/android/scoped_java_ref.h" 8 | 9 | namespace demo_jni { 10 | 11 | class DemoFoo { 12 | public: 13 | void HelloDemoFoo(JNIEnv* env, const base::android::JavaParamRef& who); 14 | }; 15 | 16 | void Hi(std::string who); 17 | void HiStatic(std::string who); 18 | } 19 | 20 | #endif //DEMO_DEMO_ANDROID_DEMO_FOO_H -------------------------------------------------------------------------------- /demo_android/demo_apk/res/layout/demo_apk_activity.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 8 | 11 | 16 | 25 | 26 | -------------------------------------------------------------------------------- /demo_android/demo_apk/res/mipmap-hdpi/app_icon.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/aikuimail/chromium_demo/be722670e693d94414e9acdace54c0caf4284df5/demo_android/demo_apk/res/mipmap-hdpi/app_icon.png -------------------------------------------------------------------------------- /demo_android/demo_apk/res/values/strings.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | Hello,DemoApk! 4 | -------------------------------------------------------------------------------- /demo_android/demo_apk/src/org/chromium/demo_apk/DemoApkActivity.java: -------------------------------------------------------------------------------- 1 | // Copyright 2012 The Chromium Authors.

添加了用户交互控制，重点在于如何控制 UI 的局部刷新及 UI 没有改变的时候的不刷新。 23 | 同时该 demo 支持使用命令行切换渲染模式以及将渲染结果保存到文件。 24 | 25 | ## demo_viz_layer_offscreen 26 | 27 | demo_viz_layer 演示使用 CopyOutput/SkiaOutputDeviceOffscreen 接口来实现 viz

`--use_virtualized_gl_contexts=0` 禁用 virtual GL Context，降低追踪的复杂度。 41 | -------------------------------------------------------------------------------- /demo_viz/demo_viz_layer_offscreen_client.h:

初始化Content模块（和Browser进程） 16 | 17 | content 通过被 services 模块启动。 18 | 19 | content实现了services 模块提供的接口，并且在 content::ContentMain() 中启动（services模块提供的） service_manager::Main() ,在这个函数中进行一些通用的初始化工作，最后（将content作为services的embedder）启动由content实现的RunEmbedderProcess()方法，至此servcies模块将控制权完全转移到content模块的ContentMainRunner。 20 | 21 | ContentMainRunner会启动ServiceManager，最后通过调用BrowserMain()将控制权转移到browser子模块。 22 | 23 | BrowserMain()通过BrowserMainRunner继续启动，BrowserMainRunner包装了BrowserMainLoop，BrowserMainLoop的主要功能包括： 24 | 25 | 1. 调用BrowserMainParts，以便允许用户的逻辑被执行； 26 | 1. 调用content::BrowserStartupComplete()，以便通知Android初始化完成； 27 | 1. 初始化主线程； 28 | 1. 创建IO线程； 29 | 1. 初始化Mojo; 30 | 1. 初始化音视频/麦克风/触摸屏等设备； 31 | 1. 初始化WebRTC; 32 | 1. 初始化剪切板相关服务； 33 | 1. 根据需求启动GPU进程； 34 | 1. 启动主线程的消息循环； 35 | 36 | BrowserMainParts作为Browser初始化的末端，用户在这里进行扩展，插入创建UI的逻辑。 37 | 38 | ``` 39 | #0 content/public/browser/browser_main_parts.cc:*() 40 | #1 content/browser/browser_main_loop.cc:*() 41 | #2 content/browser/browser_main_runner_impl.cc:*() 42 | #3 content/browser/browser_main.cc:43:BrowserMain() 43 | #4 content/app/content_main_runner_impl.cc529:RunBrowserProcessMain() 44 | #5 content/app/content_main_runner_impl.cc:978:RunServiceManager() 45 | #6 content/app/content_main_runner_impl.cc:878:Run() 46 | #7 content/app/content_service_manager_main_delegate.cc:52:RunEmbedderProcess() 47 | ``` 48 | 49 | 综上，Browser进程的初始化流程如下： 50 | content::ContentMain()->service_manager::Main()->SerivceManagerMainDelegate->ContentMainRunner->content::BrowserMain()->BrowserMainRunner->BrowserMainLoop->BrowserMainParts->(创建UI) 51 | 52 | ## 创建GPU进程 53 | 54 | TODO 55 | 56 | ## 创建UI 57 | 58 | Browser初始化完成之后，会在BrowserMainParts中创建UI。 59 | 60 | > 注意：并不是一定要在这里创建UI，因为创建UI是一个相对独立的过程，可以放在任何业务觉得合适的时机，比如放在用户打开某一个网页的时候再创建。 61 | 62 | 创建UI可以分为以下几步： 63 | 64 | 1. 创建Native窗口； 65 | 2. 创建WebContents，并将WebContents和Native窗口关联； 66 | 67 | 初始化OutputSurface 68 | 69 | ContentViewRenderView 用来显示网页内容，它内部维护了一个SurfaceView/TextureView，并且将他们的Surface传递到Native层，Native层使用它们创建OutputSurface，并且在该OutputSurface上绘制网页内容。 70 | 71 | TODO 72 | 73 | ## 创建Render进程 74 | 75 | Render进程并不会一开始就创建，而是在要打开某一个网页的时候才创建。 76 | 77 | Render进程的启动流程如下： 78 | WebContents->NavigationController->NavigationRequest->RenderFrameHostManager->SiteInstance->RenderProcessHost::Init()->ChildProcessLauncher 79 | 80 | 由于RenderProcess是按需启动的，因此它的启动流程比较复杂。 81 | 82 | TODO 83 | -------------------------------------------------------------------------------- /docs/ui.md: -------------------------------------------------------------------------------- 1 | # UI 2 | 3 | UI 分两部分，一部分是窗口，一部分是控件。 4 | 5 | chromium 中对窗口的包装包括： 6 | 7 | - aura 8 | - PlatformWindow 9 | - X11/Ozone/Windows 10 | 11 | chromium 中对UI控件的包装包括: 12 | 13 | - views 14 | - cc 15 | - viz 16 | 17 | chromium 中对渲染的包装包括: 18 | 19 | - skia 20 | - command buffer 21 | - angle 22 | - egl/opengl(es) 23 | 24 | TODO: 完善文档 25 | 26 | > views 和 WebContents 相关类图见： 27 | -------------------------------------------------------------------------------- /docs/viz.md: -------------------------------------------------------------------------------- 1 | # Viz (Visuals) 2 | 3 | > 最新文档见 [keyou.github.io/2020-07-29-how-viz-works.md](https://github.com/keyou/keyou.github.io/blob/master/_posts/2020-07-29-how-viz-works.md) 4 | 5 | `Viz` 用于 `compositing`,`gl`,`hit testing`,`media`。 6 | 7 | `Viz` 的代码在以下几个目录中： 8 | 9 | - `//services/viz`: 主要定义 viz 的 mojo 接口； 10 | - `//components/viz`: compositing 和 hit testing 部分的实现； 11 | - `//gpu`: gl 部分的实现； 12 | - `//media`: media 部分的实现； 13 | 14 | > 在 `//components/viz/demo` 下有一个官方提供的 Viz 的 demo, 这里的 demo_viz_gui 是参考那个 demo 完成的。在以上几个目录中也存放有关于 viz 的文档，这篇文档是对那些文档的总结和补充。 15 | 16 | Viz 涉及以下三个端： 17 | 18 | - `client`: 用于生成要显示的画面，至少有一个根 client，可以有多个子 client，它们组成了一个 client 树，每一个 Client 至少对应一个 FrameSinkId 和一个 LocalSurfaceId，如果父子 client 之间的 UI 需要嵌入，则子 client 作为 SurfaceDrawQuad 嵌入到父 client 中； 19 | - `host`： 用于注册 client 端，只能运行在特权端，负责协助 client 建立起和 service 的连接，从而建立 client 和 client 之间的树形关系； 20 | - `service`: 运行 Viz 的内核，进行UI合成以及最终的渲染，host 和 client 都需要和它交互。 21 | 22 | > 以上描述比较抽象，简单理解就是： 运行 `viz::mojom::FrameSinkMnagerClient` 的端叫做 host，运行 `viz::mojom::FrameSinkManager` 和 `viz::mojom::CompositorFrameSink` 的端叫 service, 运行 `viz::mojom::CompositorFrameSinkClient` 的端叫 client。 23 | 24 | ## 主要概念解释 25 | 26 | - `viz::mojom::CompositorFrameSinkClient (CFSC)` = Client：表示一个画面的来源； 27 | - `viz::mojom::CompositorFrameSink (CFS)` = FrameSink (FS)：用于处理 CF 的地方，每一个 FrameSink 都单独处理某一部分的画面； 28 | - `viz::mojom::FrameSinkManager (FSM)` = FrameSinkManager：用于管理 CFS, 包括其创建和销毁； 29 | - `viz::CompositorFrame (CF)` = Frame：表示一个画面，可以是一帧完整的画面或者某一个区域的画面，它内部保存一个 `viz::RenderPass` 的列表； 30 | - `viz::RenderPass`：内部包含了一个 `viz::DrawQuad` 的列表； 31 | - `viz::DrawQuad`：包含具体的显示内容，目前共有 9 种显示内容，有简单的 DrawQuad，比如图片，视频，纯色等，也有用于嵌套的 DrawQuad，比如使用 `RenderPassDrawQuad` 可以嵌入其他的 RenderPass，使用 `SurfaceDrawQuad` 可以嵌入其他的 `viz::Surface` 等。 32 | - `viz::Surface`: 内部维护了 2 个 CompositorFrame 对象，分别为 ActiveFrame 和 PendingFrame，当 CF 所表示的画面的 size 或者 scale factor 改变的时候，会创建新的 Surface； 33 | 34 | > DrawQuad 类型列表：([draw_quad.h](https://source.chromium.org/chromium/chromium/src/+/master:components/viz/common/quads/draw_quad.h)) 35 | kPictureContent, 36 | kRenderPass, 37 | kSolidColor, 38 | kStreamVideoContent, 39 | kSurfaceContent, 40 | kTextureContent, 41 | kTiledContent, 42 | kYuvVideoContent, 43 | kVideoHole. 44 | 45 | ## Viz 的 Id 设计 46 | 47 | 每一个 client 都至少对应一个 `FrameSinkId` 和 `LocalSurfaceId`，在 client 的整个生命周期中所有 FrameSink 的 `client_id`（见下文）都是固定的，而 `LocalSurfaceId` 会根据 client 显示画面的 size 或 scale factor 的改变而改变。他们两个共同组成了 `SurfaceId`，用于在 service 端全局标识一个 `Surface` 对象。也就是说对于每一个 `Surface`，都可以获得它是由谁在什么 size 或 scale facotr 下产生的。 48 | 49 | ### `FrameSinkId` 50 | 51 | - `client_id` = uint32_t, 每个 client 都会有唯一的一个 ClientId 作为标识符，标识一个 CompositorFrame 是由哪个 client 产生的，也就是标识 CompositorFrame 的来源； 52 | - `sink_id` = uint32_t, 在 service 端标识一个 CompositorFrameSink 实例，Manager 会为每个 client 在 service 端创建一个 CompositorFrameSink，专门用于处理该 client 生成的 CompositorFrame，也就是标识 CompositorFrame 的处理端； 53 | - `FrameSinkId = client_id + sink_id`，将 CF 的来源和处理者关联起来。 54 | 55 | FrameSinkId 可以由 `FrameSinkIdAllocator` 辅助类生成。 56 | 57 | > 什么时候需要使用单 client 多 FrameSink？ 58 | （以下为推测，没有验证。TODO: 验证以下想法。） 59 | 在实际使用中，往往一个进程就是一个 client，专门负责一个业务模块 UI 的实现，而一个业务往往由很多的 UI 元素组成，因此可以让每个 FrameSink 负责一部分的 UI，此时就需要单使用单 client 多 FrameSink 的机制了，这种机制可以实现 UI 的局部刷新。当然，多 client 也能实现这一点，从设计上来讲，此时 client_id 的设计意义以及允许单 client 多 FrameSink 的设计意义就没有那么大了。所以推测在 chrome 中浏览器主程序是一个 client，而每一个插件都是一个独立的 client。 60 | 61 | ### `LocalSurfaceId` 62 | 63 | - `parent_sequence_number` = uint32_t, 当自己作为父 client，并且 surface 的 size 和 device scale factor 改变的时候改变； 64 | - `child_sequence_number` = uint32_t, 当自己作为子 client，并且 surface 的 size 和 device scale factor 改变的时候改变； 65 | - `embed_token` = 可以理解为一个随机数， 用于避免 LocalSurafaceId 可猜测，当父 client 和子 client 的父子关系改变的时候改变； 66 | - `LocalSurfaceId = parent_sequence_number + child_sequence_number + embed_token`，当 client 的 size 当前 client 产生的画面改变。 67 | 68 | LocalSurfaceId 可以由 `ParentLocalSurfaceIdAllocator` 或者 `ChildLocalSurfaceIdAllocator` 这两个辅助类生成。前者用于由父 client 负责生成自己的 LocalSurfaceId 的时候，后者用于由子 client 自己负责生成自己的 LocalSurfaceId 的时候。使用哪种方式要看自己的 UI 组件之间的依赖关系的设计。 69 | 70 | LocalSurfaceId 在很多时候都包装在 `LocalSurfaceIdAllocation` 内，该类记录了 LocalSurfaceId 的创建时间。改时间在创建 CF 的时候需要用到。 71 | 72 | ### `SurfaceId` 73 | 74 | `SurfaceId = FrameSinkId + LocalSurfaceId` 75 | 76 | SurfaceId 全局唯一记录一个显示画面，它可以被嵌入其他的 CF 或者 RenderPass 中，从而实现显示界面的嵌入和局部刷新。 77 | 78 | ##
