将自定义 Android 11 内核加载到 AVD/模拟器

Question

我希望能够构建自定义内核并在 Android 虚拟设备 (AVD) 上运行它。我已尝试执行以下说明，但它会导致启动循环。我按照此处的说明进行操作：https://source.android.com/setup/build/building-kernels下载 Android 内核源代码。

同步并构建

repo init -b common-android-mainline && repo sync
repo sync
BUILD_CONFIG=common/build.config.x86_64 build/build.sh

使用 Pixel 4、API 30、ABI x86_64 AVD 运行模拟器

emulator @Pixel_4_API_30 -kernel out/android-mainline/dist/bzImage -show-kernel -verbose

这些是设备重新启动之前发生的一些行：

android::init::BlockDevInitializer::InitDevices(std::set<std::string>): partition(s) not found in /sys, waiting for their uevent(s): metadata, super, vbmeta
[   10.888602] init: Wait for partitions returned after 10010ms
[   10.889489] init: bool android::init::BlockDevInitializer::InitDevices(std::set<std::string>): partition(s) not found after polling timeout: metadata, super, vbmeta
[   10.891648] init: Failed to mount required partitions early ...
[   10.892517] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00

内核必须匹配virtual_device，虚拟设备相关模块会被打包到ramdisk中，所以你的ramdisk也必须更新

下面是内核编译产物，所有ko都需要同步到ramdisk

你需要： cp dist/* aosp/kernel/prebuilts/common-modules/virtual-device/5.10/x86-64/
