A partire dal 27 marzo 2025, ti consigliamo di utilizzare android-latest-release anziché aosp-main per compilare e contribuire ad AOSP. Per ulteriori informazioni, vedi Modifiche ad AOSP.

Di seguito sono riportate le sorgenti del kernel per lo sviluppo del kernel sui dispositivi Cuttlefish.
Sviluppare kernel Android
Per sviluppare kernel sui dispositivi Cuttlefish:
Clona il manifest del repository del kernel appropriato per il tuo dispositivo Cuttlefish e apporta le modifiche necessarie.
mkdir common-android-mainline
cd common-android-mainline
repo init -u https://android.googlesource.com/kernel/manifest -b common-android-mainline
repo sync -c -j$(nproc) -q
Compila il kernel e il ramdisk. Per ulteriori informazioni, consulta
Costruzione dei moduli del fornitore per il dispositivo virtuale.
tools/bazel run //common-modules/virtual-device:virtual_device_x86_64_dist
Se utilizzi i manifest del kernel common-android-4.19-stable, common-android-4.14-stable o
common-android11-5.4, esegui:
BUILD_CONFIG=common/build.config.gki.x86_64 build/build.sh && BUILD_CONFIG=common-modules/virtual-device/build.config.cuttlefish.x86_64 build/build.sh
Invece di eseguire il build localmente (per evitare di scaricare il codice sorgente del kernel e di configurare un ambiente di sviluppo del kernel), puoi scaricare gli elementi pertinenti da ci.android.com.
Avvia il kernel e il ramdisk con Cuttlefish.
cvd create \
-kernel_path=./out/virtual_device_x86_64/dist/bzImage \
-initramfs_path=./out/virtual_device_x86_64/dist/initramfs.img
Se avvii un kernel non GKI (qualsiasi versione precedente o uguale a 4.19), ometti l'argomento -initramfs_path.
Se avvii il kernel su una versione aarch64 di Cuttlefish, utilizza la configurazione di compilazione aarch64 e l'elemento Image anziché bzImage.
cvd create \
-kernel_path=./out/virtual_device_aarch64/dist/Image \
-initramfs_path=./out/virtual_device_aarch64/dist/initramfs.img

Clone the appropriate kernel repo manifest for your Cuttlefish device and\n make any changes.\n\n mkdir common-android-mainline\n cd common-android-mainline\n repo init -u https://android.googlesource.com/kernel/manifest -b common-android-mainline\n repo sync -c -j$(nproc) -q\n\n2. Build the kernel and ramdisk. For more information, see\n [Building the Vendor Modules for the Virtual Device](/docs/setup/build/building-kernels#building-gki-modules).\n\n tools/bazel run //common-modules/virtual-device:virtual_device_x86_64_dist\n\n If using `common-android-4.19-stable`, `common-android-4.14-stable`, or\n `common-android11-5.4` kernel manifests, run: \n\n BUILD_CONFIG=common/build.config.gki.x86_64 build/build.sh && BUILD_CONFIG=common-modules/virtual-device/build.config.cuttlefish.x86_64 build/build.sh\n\n Instead of building locally (to avoid downloading the kernel source,\n setting up a kernel development environment), you can download the relevant\n artifacts at ci.android.com.\n - [`android-mainline`](https://ci.android.com/builds/branches/aosp_kernel-common-android-mainline/grid?)\n - [`android16-6.12`](https://ci.android.com/builds/branches/aosp_kernel-common-android16-6.12/grid?)\n - [`android15-6.6`](https://ci.android.com/builds/branches/aosp_kernel-common-android15-6.6/grid?)\n - [`android14-6.1`](https://ci.android.com/builds/branches/aosp_kernel-common-android14-6.1/grid?)\n - [`android14-5.15`](https://ci.android.com/builds/branches/aosp_kernel-common-android14-5.15/grid?)\n - [`android13-5.15`](https://ci.android.com/builds/branches/aosp_kernel-common-android13-5.15/grid?)\n - [`android13-5.10`](https://ci.android.com/builds/branches/aosp_kernel-common-android13-5.10/grid?)\n - [`android12-5.10`](https://ci.android.com/builds/branches/aosp_kernel-common-android12-5.10/grid?)\n - [`android12-5.4`](https://ci.android.com/builds/branches/aosp_kernel-common-android12-5.4/grid?)\n - [`android11-5.4`](https://ci.android.com/builds/branches/aosp_kernel-common-android11-5.4/grid?)\n3. Launch the kernel and ramdisk with Cuttlefish.\n\n cvd create \\\n -kernel_path=./out/virtual_device_x86_64/dist/bzImage \\\n -initramfs_path=./out/virtual_device_x86_64/dist/initramfs.img\n\n If launching a non-GKI kernel (anything at or under\n 4.19), omit the `-initramfs_path` argument.\n\n If you're launching the kernel on an aarch64 version of Cuttlefish, use the\n `aarch64` build configuration and use the `Image` artifact instead of\n `bzImage`. \n\n cvd create \\\n -kernel_path=./out/virtual_device_aarch64/dist/Image \\\n -initramfs_path=./out/virtual_device_aarch64/dist/initramfs.img"]]
