本頁展示如何在ARM64
上建立和啟動支援 16KB 頁面大小的 Cuttlefish。本頁的說明假定您的電腦中安裝了 Cuttlefish。有關安裝說明,請參閱安裝 Cuttlefish 。
同步和建立與頁面無關的目標
使用與頁面無關的目標建立並啟動 Cuttlefish:
$ mkdir main && cd main
$ repo init -u https://android.googlesource.com/platform/manifest -b main
$ repo sync -c -j32
# Build cf agnostic target.
$ source build/envsetup.sh
$ lunch aosp_cf_arm64_phone_pgagnostic-trunk-userdebug
$ m
# Launch cf with a kernel with 16KB page size support.
$ launch_cvd
...

驗證頁面大小和啟動
若要驗證頁面大小和啟動狀態:
以 root 身分存取 shell:
$ adb root adbd is already running as root $ adb shell vsoc_arm64_pgagnostic:/ #
驗證頁面大小和啟動狀態:
vsoc_arm64_pgagnostic:/ # getconf PAGE_SIZE 16384 vsoc_arm64_pgagnostic:/ # getprop | grep sys.boot.completed sys.boot_completed: 1
使用帶有自訂 16KB 頁面大小內核的 Cuttlefish
要使用自訂核心而不是預先建置核心:
為 android 通用核心建立一個 repo 目錄並同步該目錄:
$ mkdir common-android14-6.1 && cd common-android14-6.1 $ repo init -u https://android.googlesource.com/kernel/manifest -b common-android14-6.1 $ repo sync -c -j$(nproc)
建構 16KB 頁大小核心:
$ tools/bazel run --lto=none //common:kernel_aarch64_16k_dist $ tools/bazel run --lto=none //common-modules/virtual-device:virtual_device_aarch64_16k_dist -- \ --dist_dir=out/android14-6.1/dist
驗證建置是否成功執行:
# Generated files $ ls out/android14-6.1/dist/Image $ ls out/android14-6.1/dist/initramfs.img
使用自訂 16KB 頁面大小核心啟動 Cuttlefish
要在 Cuttlefish 中使用新建的核心:
$ launch_cvd -kernel_path ~/common-android14-6.1/out/android14-6.1/dist/Image \
-initramfs_path ~/common-android14-6.1/out/android14-6.1/dist/initramfs.img \
--resume=false --userdata_format=ext4 \
--data_policy=always_create --blank_data_image_mb=8000
-userdata_format=ext4
