java - AOSP SurfaceFlinger 在哪里启动？

Question

SurfaceFlinger在 Android 图形渲染中必不可少。我研究并发现了一些关于surfaceflinger的代码。这是它的主要内容:https://android.googlesource.com/platform/frameworks/native/+/refs/tags/android-11.0.0_r28/services/surfaceflinger/main_surfaceflinger.cpp
我找不到与启动相关的任何内容 surfaceflinger在 init.rc :https://android.googlesource.com/platform/system/core/+/refs/tags/android-11.0.0_r28/rootdir/init.rc
我在这里找到:https://proandroiddev.com/how-android-boot-up-9864376d911c该surfaceflinger是由SystemServer启动的.于是我找到了 SystemServer源代码在这里:https://android.googlesource.com/platform/frameworks/base/+/refs/tags/android-11.0.0_r28/services/java/com/android/server/SystemServer.java但我没有看到提到 SurfaceFlinger/surfaceflinger或 Surface Flinger有一个surfaceflinger.rc Surface Flinger 目录中的文件，但我找不到任何包含它的文件:https://android.googlesource.com/platform/frameworks/native/+/refs/tags/android-11.0.0_r28/services/surfaceflinger/surfaceflinger.rcsurfaceflinger在哪里服务在Android中启动？

There is a surfaceflinger.rc file in the Surface Flinger directory but I couldn t find any file that includes it: https://android.googlesource.com/platform/frameworks/native/+/refs/tags/android-11.0.0_r28/services/surfaceflinger/surfaceflinger.rc

它在这里: https://android.googlesource.com/platform/frameworks/native/+/refs/tags/android-11.0.0_r28/services/surfaceflinger/Android.bp#253 init_rc:["surfaceflinger.rc"] :

cc_binary {
    name: "surfaceflinger",
    defaults: ["libsurfaceflinger_binary"],
    init_rc: ["surfaceflinger.rc"],
    srcs: [":surfaceflinger_binary_sources"],
    shared_libs: [
        "libsurfaceflinger",
        "libSurfaceFlingerProp",
    ],
}
