 This folder contains a skeleton audio control HAL implementation in Rust to
 demonstrate  how vendor may implement a Rust audio control HAL. To run this
 audio control HAL, include
-`android.hardware.automotive.audiocontrol-V4-rust-service` in your image.
+`android.hardware.automotive.audiocontrol-rust-service` in your image.
 
 This implementation returns `StatusCode::UNKNOWN_ERROR` for all operations
 and does not pass VTS/CTS. Vendor must replace the logic in

+# AIDL VHAL libraries and reference implementation.
+---
+
+This directory stores the libraries useful for implementing vendor AIDL VHAL.
+This directory also stores a reference fake implementation for AIDL VHAL.
+
+## default_config
+
+Stores the default vehicle property configurations for reference vehicle HAL.
+Vendor implementation could copy this library but must update the configuration
+to meet their own requirements, e.g. enable or disable certain properties or
+update the initial value for certain properties.
+
+##	fake_impl
+
+Contains libraries used specifically for the fake reference VHAL implementation.
+These libraries are for test only and must not be directly used for vendor
+VHAL implementation.
+
+These libraries contain test-spcific logic and must not run directly on a real
+vehicle.
+
+## grpc
+
+Stores code for GRPC based VHAL implementation.
+
+## hardware
+
+Defines an interface `IVehicleHardware.h` which vendor must implement for
+vehicle-specific logic if they want to follow our reference VHAL design.
+
+## proto
+
+Stores Some protobuf files translated from AIDL VHAL interface types. These
+files are used in GRPC VHAL implementation.
+
+## utils
+
+Defines a library `VehicleHalUtils-V3` which provides useful utility functions for
+VHAL implementation. Vendor VHAL could use this library.
+
+## vhal
+
+Defines a library `DefaultVehicleHal` which provides generic logic for all VHAL
+implementations (including reference VHAL). Vendor VHAL implementation could
+use this library, along with their own implementation for `IVehicleHardware`
+interface.
+
+Also defines a binary `android.hardware.automotive.vehicle@V3-default-service`
+which is the reference VHAL implementation. It implements `IVehicle.aidl`
+interface. It uses `DefaultVehicleHal`, along with `FakeVehicleHardware`
+(in fake_impl). It simulates the vehicle bus interaction by using an
+in-memory map. Meaning that all properties (except for some special ones) are
+just written into a hash map and read from a hash map without relying on any
+hardware. As a result, the reference implementation can run on emulator or
+any host environment.
+
+Vendor must not directly use the reference implementation for a real vehicle.

+# Fake reference AIDL VHAL implementation libraries
+---
+
+This directory stores libraries for implementing a fake reference AIDL VHAL.
+
+WARNING: All the libraries here are for TEST ONLY.
+
+## GeneratorHub
+
+Defines a library `FakeVehicleHalValueGenerators-V3` that could generate fake
+vehicle property values for testing.
+
+## hardware
+
+Defines a fake implementation for device-specifc interface `IVehicleHardware`:
+`FakeVehicleHardware`. This implementation uses a in-memory map for storing
+property values and does not communicate with or depending on any specific
+vehicle bus.
+
+## obd2frame
+
+Defines a library `FakeObd2Frame` that generates fake OBD2 frame for OBD2
+properties.
+
+## userhal
+
+Defines a library `FakeUserHal` that emulates a real User HAL behavior by
+parsing debug commands.

+// This class provides a pool of recyclable VehiclePropertyValue objects.
+//
+// It has only one overloaded public method - obtain(...), users must call this method when new
+// object is needed with given VehiclePropertyType and vector size (for vector properties). This
+// method returns a recyclable smart pointer to VehiclePropertyValue, essentially this is a
+// std::unique_ptr with custom delete function, so recyclable object has only one owner and
+// developers can safely pass it around. Once this object goes out of scope, it will be returned to
+// the object pool.
+//
+// Some objects are not recyclable: strings and vector data types with vector
+// length > maxRecyclableVectorSize (provided in the constructor). These objects will be deleted
+// immediately once the go out of scope. There's no synchronization penalty for these objects since
+// we do not store them in the pool.
+//
+// This class is thread-safe. Users can obtain an object in one thread and pass it to another.
+//
+// Sample usage:
+//
+//   VehiclePropValuePool pool;
+//   auto v = pool.obtain(VehiclePropertyType::INT32);
+//   v->propId = VehicleProperty::HVAC_FAN_SPEED;
+//   v->areaId = VehicleAreaSeat::ROW_1_LEFT;
+//   v->timestamp = elapsedRealtimeNano();
+//   v->value->int32Values[0] = 42;

+// object is needed with given VehiclePropertyType and vector size (for vector properties). This
+// method returns a recyclable smart pointer to VehiclePropertyValue, essentially this is a
+// std::unique_ptr with custom delete function, so recyclable object has only one owner and
+// developers can safely pass it around. Once this object goes out of scope, it will be returned to
+// the object pool.

+// Some objects are not recyclable: strings and vector data types with vector
+// length > maxRecyclableVectorSize (provided in the constructor). These objects will be deleted
+// immediately once the go out of scope. There's no synchronization penalty for these objects since
+// we do not store them in the pool.
+//
+// This class is thread-safe. Users can obtain an object in one thread and pass it to another.

+//   v->propId = VehicleProperty::HVAC_FAN_SPEED;

-// object is needed with given VehiclePropertyType and vector size (for vector properties). This
-// method returns a recyclable smart pointer to VehiclePropertyValue, essentially this is a
-// std::unique_ptr with custom delete function, so recyclable object has only one owner and
-// developers can safely pass it around. Once this object goes out of scope, it will be returned to
-// the object pool.
-//
-// Some objects are not recyclable: strings and vector data types with vector
-// length > maxRecyclableVectorSize (provided in the constructor). These objects will be deleted
-// immediately once the go out of scope. There's no synchronization penalty for these objects since
-// we do not store them in the pool.
-//
-// This class is thread-safe. Users can obtain an object in one thread and pass it to another.
-//
-// Sample usage:
-//
-//   VehiclePropValuePool pool;
-//   auto v = pool.obtain(VehiclePropertyType::INT32);
-//   v->propId = VehicleProperty::HVAC_FAN_SPEED;

+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking

+// You must not make a backward incompatible change to any AIDL file built

+// type is used to build AIDL files in a way that they can be used across

 ### Support for Android Virtualization Framework
 
-The Android Virtualization Framwork (AVF) relies on RKP to provision keys for VMs. A
-privileged vm, the RKP VM, is reponsible for generating and managing the keys for client
-VMs that run virtualized workloads. See the following for more background information on the
-RKP VM:
-*    [rkp-vm](https://android.googlesource.com/platform/packages/modules/Virtualization/+/main/service_vm/README.md#rkp-vm-remote-key-provisioning-virtual-machine)
-*    [rkp-service](https://source.android.com/docs/core/ota/modular-system/remote-key-provisioning#stack-architecture)
+The Android Virtualization Framework (AVF) relies on RKP to provision keys for
+VMs. There are a privileged set of VMs that RKP will recognise and provision
+keys to for specific applications, like Widevine, and for services, like
+[VM attestation][vm-attestation]. These privileged VMs are identified by their
+DICE chain through a combination of the [RKP VM marker][rkp-vm-marker]
+(key `-70006`) and the component name.
 
-It is important to distinquish the RKP VM from other components, such as KeyMint. An
-[RKP VM marker](https://pigweed.googlesource.com/open-dice/+/HEAD/docs/android.md#configuration-descriptor)
-(key `-70006`) is used for this purpose. The existence or absence of this marker is used to
-identify the type of component decribed by a given DICE chain.
+[vm-attestation]: http://android.googlesource.com/platform/packages/modules/Virtualization/+/main/docs/vm_remote_attestation.md
+[rkp-vm-marker]: https://pigweed.googlesource.com/open-dice/+/HEAD/docs/android.md#configuration-descriptor
 
-The following describes which certificate types may be request based on the RKP VM marker:
-1. "rkp-vm": If a DICE chain has zero or more certificates without the RKP VM
-   marker followed by one or more certificates with the marker, then that chain
-   describes an RKP VM. If there are further certificates without the RKP VM
-   marker, then the chain does not describe an RKP VM.
+If a DICE chain begins from the root with zero or more certificates without
+the RKP VM marker, followed by only certificates with the marker up to and
+including the leaf certificate, then that chain describes a VM that RKP might
+provision keys to. Implementations must include the first RKP VM marker as early
+as possible after the point of divergence between TEE and non-TEE components in
+the DICE chain, prior to loading the Android Bootloader (ABL).
 
-   Implementations must include the first RKP VM marker as early as possible
-   after the point of divergence between TEE and non-TEE components in the DICE
-   chain, prior to loading the Android Bootloader (ABL).
-2. "widevine" or "keymint": If there are no certificates with the RKP VM
-   marker then it describes a TEE component.
-3. None: Any component described by a DICE chain that does not match the above
-   two categories.
+The component name of the leaf certificate then identifies the kind of keys for
+RKP to provision:
+
+*   "rkp-vm": for VM attestation keys managed by the [service VM][service-vm]
+*   "keymint": for Android attestation keys
+*   "widevine": for Widevine keys
+
+[service-vm]: https://android.googlesource.com/platform/packages/modules/Virtualization/+/main/service_vm/README.md#rkp-vm-remote-key-provisioning-virtual-machine
+
+If there are no certificates with the RKP VM marker in the DICE chain then it
+describes a TEE component that can be provisioned with Widevine and Android
+attestation keys.
+
+Any remaining DICE chains describe a component to which RKP will not provision
+keys.

+# AuthMgr
+
+The AuthMgr protocol authenticates and authorizes clients before they can
+access trusted HALs, AIDL-defined services in trusted execution environments.
+Version 1 was designed to allow applications running in a protected virtual
+machine (pVM) to access services running in a TEE in ARM TrustZone. An
+implementation of `IAuthMgrAuthorization` is referred to as an AuthMgr Backend.
+An implementation of a client of the AuthMgr Backend is referred to as an
+AuthMgr Frontend.
+
+
+## Additional Requirements by Android Version
+
+The comments on `IAuthMgrAuthorization` describe the requirements for implementing
+an AuthMgr Backend (implementor of the interface) itself. There are some additional
+requirements that are specific to Android release versions.
+
+### Android 16
+- If implementing `IAuthMgrAuthorization` in Android 16 only one AuthMgr Backend is
+supported and dynamic service discovery is not supported. The AuthMgr Backend
+service must be exposed on secure partition ID 0x8001 over VSOCK port 1.
+
+- AuthMgr Front Ends must implement the "android.16" profile as described in the
+[Android Profile for DICE](https://pigweed.googlesource.com/open-dice/+/HEAD/docs/android.md#versions)

+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+//     the interface (from the latest frozen version), the build system will
+//     prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+// type is used to build AIDL files in a way that they can be used across
