我正在尝试通过自定义编译内核启动 android 模拟器。我从android存储库下载了金鱼内核并使用了分支origin/android-goldfish-3.10，我能够通过这些命令成功编译内核。
$ export ARCH=x86
$ export CROSS_COMPILE=x86_64-linux-android-
$ export PATH=$(pwd)/x86_64-linux-android-4.7/bin:$PATH
$ make i386_ranchu_defconfig
$ make -j6
Kernel: arch/x86/boot/bzImage is ready (#4)
编译内核后，我使用此命令启动了模拟器。
$ cd $ANDROID_SDK_ROOT
$ ./tools/emulator -debug init -kernel $HOME/goldfish/arch/x86/boot/bzImage -system ./system-images/android-22/google_apis/x86/system.img -ramdisk ./system-images/android-22/google_apis/x86/ramdisk.img -avd Nexus_5_API_22 -wipe-data -qemu -enable-kvm
它正在启动android模拟器，但模拟器只显示黑屏而不启动。
