+/**
+ * The Audio Eraser Effect is an audio effect that combines multiple capabilities to manipulate and
+ * enhance audio streams.
+ *
+ * The Audio Eraser Effect integrates three primary components:
+ *
+ * Sound Separator: Detects and splits the input audio into multiple sound sources.
+ * Sound Classifier: Classifies each separated sound source into predefined categories based on the
+ * AudioSet ontology.
+ * Remixer: Adjusts the gain factor (volume) of each classified sound source according to specified
+ * configurations, then recombines them into a single output audio stream.
+ *
+ * The Audio Eraser Effect operates in different modes, each leveraging a subset of these
+ * components to achieve specific functionalities as defined in `android.media.audio.eraser.Mode`.
+ *
+ * Flow Diagrams for each operation mode as below.

+namespace aidl::android::hardware::audio::core::deprecated {
+
+// 'StreamSwitcher' is an implementation of 'StreamCommonInterface' which allows
+// dynamically switching the underlying stream implementation based on currently
+// connected devices. This is achieved by replacing inheritance from
+// 'StreamCommonImpl' with owning an instance of it. StreamSwitcher must be
+// extended in order to supply the logic for choosing the stream
+// implementation. When there are no connected devices, for instance, upon the
+// creation, the StreamSwitcher engages an instance of a stub stream in order to
+// keep serving requests coming via 'StreamDescriptor'.
+//
+// StreamSwitcher implements the 'IStreamCommon' interface directly, with
+// necessary delegation to the current stream implementation. While the stub
+// stream is engaged, any requests made via 'IStreamCommon' (parameters, effects
+// setting, etc) are postponed and only delivered on device connection change
+// to the "real" stream implementation provided by the extending class. This is why
+// the behavior of StreamSwitcher in the "stub" state is not identical to behavior
+// of 'StreamStub'. It can become a full substitute for 'StreamStub' once
+// device connection change event occurs and the extending class returns
+// 'LEAVE_CURRENT_STREAM' from 'switchCurrentStream' method.
+//
+// There is a natural limitation that the current stream implementation may only
+// be switched when the stream is in the 'STANDBY' state. Thus, when the event
+// to switch the stream occurs, the current stream is stopped and joined, and
+// its last state is validated. Since the change of the set of connected devices
+// normally occurs on patch updates, if the stream was not in standby, this is
+// reported to the caller of 'IModule.setAudioPatch' as the 'EX_ILLEGAL_STATE'
+// error.
+//
+// The simplest use case, when the implementor just needs to emulate the legacy HAL API
+// behavior of receiving the connected devices upon stream creation, the implementation
+// of the extending class can look as follows. We assume that 'StreamLegacy' implementation
+// is the one requiring to know connected devices on creation:
+//
+//   class StreamLegacy : public StreamCommonImpl {
+//     public:
+//       StreamLegacy(StreamContext* context, const Metadata& metadata,
+//                    const std::vector<AudioDevice>& devices);

+//           // This implementation effectively postpones stream creation until
+//           // receiving the first call to 'setConnectedDevices' with a non-empty list.

-namespace aidl::android::hardware::audio::core {
-
-// 'StreamSwitcher' is an implementation of 'StreamCommonInterface' which allows
-// dynamically switching the underlying stream implementation based on currently
-// connected devices. This is achieved by replacing inheritance from
-// 'StreamCommonImpl' with owning an instance of it. StreamSwitcher must be
-// extended in order to supply the logic for choosing the stream
-// implementation. When there are no connected devices, for instance, upon the
-// creation, the StreamSwitcher engages an instance of a stub stream in order to
-// keep serving requests coming via 'StreamDescriptor'.
-//
-// StreamSwitcher implements the 'IStreamCommon' interface directly, with
-// necessary delegation to the current stream implementation. While the stub
-// stream is engaged, any requests made via 'IStreamCommon' (parameters, effects
-// setting, etc) are postponed and only delivered on device connection change
-// to the "real" stream implementation provided by the extending class. This is why
-// the behavior of StreamSwitcher in the "stub" state is not identical to behavior
-// of 'StreamStub'. It can become a full substitute for 'StreamStub' once
-// device connection change event occurs and the extending class returns
-// 'LEAVE_CURRENT_STREAM' from 'switchCurrentStream' method.
-//
-// There is a natural limitation that the current stream implementation may only
-// be switched when the stream is in the 'STANDBY' state. Thus, when the event
-// to switch the stream occurs, the current stream is stopped and joined, and
-// its last state is validated. Since the change of the set of connected devices
-// normally occurs on patch updates, if the stream was not in standby, this is
-// reported to the caller of 'IModule.setAudioPatch' as the 'EX_ILLEGAL_STATE'
-// error.
-//
-// The simplest use case, when the implementor just needs to emulate the legacy HAL API
-// behavior of receiving the connected devices upon stream creation, the implementation
-// of the extending class can look as follows. We assume that 'StreamLegacy' implementation
-// is the one requiring to know connected devices on creation:
-//
-//   class StreamLegacy : public StreamCommonImpl {
-//     public:
-//       StreamLegacy(StreamContext* context, const Metadata& metadata,
-//                    const std::vector<AudioDevice>& devices);

-//           // This implementation effectively postpones stream creation until
-//           // receiving the first call to 'setConnectedDevices' with a non-empty list.
-//           return isStubStream() ? DeviceSwitchBehavior::CREATE_NEW_STREAM :

 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

These values must match the values in supportedValuesList of VEHICLE_DRIVING_AUTOMATION_CURRENT_LEVEL.\nFor the property that communicates the current state of autonomy, see VEHICLE_DRIVING_AUTOMATION_CURRENT_LEVEL."

+# 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.

-// 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;

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

+// 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.

+     * 5G TS 38.331 cipheringDisabled and integrityProtection
+     * ======================================================
+     * For most connections, generally what is reported by the network is what ends up being used.
+     * There are two significant cases where this may not be the case. In 5G, per the introduction
+     * of network configuration options cipheringDisabled and integrityProtection (TS 38.331), the
+     * network can have declared certain security algorithms to be used while also requiring a null
+     * algorithm via those parameters.
+     *
+     *
+     * Exceptions for DRBs with null integrity (pre-5G Rel 16)
+     * =======================================================
+     * When reporting the SecurityAlgorithm for a ConnectionType which includes a DRB, there is an
+     * exception where a DRB with null integrity is not to be considered/included in reporting
+     * except for 5G Rel 16 connections and newer. Because DRBs almost always use null integrity in
+     * practice, and thus if included the report would always be null, rendering the report
+     * useless. For anything 5G Rel 16 or newer, accurate reporting for the DRB's integrity is
+     * required.
+     *
+     *
+     * NRDC MCG and SCGs
+     * =================
+     * In the NRDC case, there can be two sets of algorithms, one for the MCG (Master Cell Group)
+     * and one for the SCG (Secondary Cell Group). In this case, always send a combined update that
+     * reflects the weaker of the algorithms, e.g. (weakest) NEA0 < NEA1 < NEA2 < NEA3 (strongest).
+     * This applies to both the ciphering and integrity algorithms.
+     *
+     *
+     * Determining the value of isUnprotectedEmergency
+     * ===============================================
+     * 2G: isUnprotectedEmergency is true if the ciphering algorithm is NULL.
+     * 3G: isUnprotectedEmergency is true if the ciphering and integrity algorithm are NULL.
+     * 4G: isUnprotectedEmergency is true if the ciphering algorithm is NULL.
+     * 5G: isUnprotectedEmergency is true if the ciphering algorithm is NULL.
+     * Notes:
+     *    - On integrity: In 4G, PDCP can be LTE-based or NR-based. Starting from 5G Rel 17, only
+     *      the NR-based PDCP supports DRB integrity. As the PDCP version can change during a DRB's
+     *      operation, it becomes complicated when integrity is used to determine whether an
+     *      emergency call is protected or not, hence its exclusion to simplify implementation.
+     *    - 4G and 5G with multiple DRBs : emergency calls are protected under that RAT only if all
+     *      SRBs and DRBs are protected (including IMS DRB).
+     *    - 4G and 5G DRB integrity: Since DRB integrity is not enabled in most networks, if both
+     *      ciphering and integrity are taken into account to determine the value of
+     *      isUnprotectedEmergency, the value will mostly be false, hence why it is excluded.

+
+As noted in the section [General approach](#general-approach), the UDS\_pub may

+X.509v3 public key certificates are the only supported mechanism for

+additional requirements that must be met for the certificates:
+
+*   [`BasicConstraints`](https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.9)
+    *   All CA certificates must include this as a critical extension.
+    *   `pathLenConstraint` must be set correctly in each CA certificate to
+        limit the maximum chain length.
+    *   `cA` must be set to true for all certificates except the leaf
+        certificate.
+    *   `BasicConstraints` must be absent for the leaf/UDS certificate.
+    *   Consider the chain `root -> intermediate -> UDS_pub`. In such a chain,
+        `BasicConstraints` must be:
+        *   `{ cA: TRUE, pathLenConstraint: 1}` for the root certificate
+        *   `{ cA: TRUE, pathLenConstraint: 0}` for the intermediate certificate
+        *   Absent for the UDS certificate
+*   [`KeyUsage`](https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.3)
+    *   All certificates in a UDS certificate chain must include this as a
+        critical extension.
+    *   CA certificates must set `KeyUsage` to only `keyCertSign`.
+    *   The UDS certificate must set `KeyUsage` to only `digitalSignature`.
+
+### Supported Algorithms
+
+UDS certificates must be signed using one of the following allowed algorithms:
+
+*   `ecdsa-with-SHA256`
+    ([RFC 5758](https://www.rfc-editor.org/rfc/rfc5758#section-3.2))
+    *   Note: this algorithm is only usable with ECDSA P-256 keys
+*   `ecdsa-with-SHA384`
+    ([RFC 5758](https://www.rfc-editor.org/rfc/rfc5758#section-3.2))
+    *   Note: this algorithm is only usable with ECDSA P-384 keys
+*   `id-Ed25519` ([RFC 8410](https://www.rfc-editor.org/rfc/rfc8410#section-3))
+

+/**
+ * This is the interface to be implemented by an AuthMgr backend component (AuthMgr BE), in order to
+ * allow the AuthMgr frontend component (AuthMgr FE) in a pVM instance to authenticate itself and
+ * to authorize one or more clients in the pVM instance, in order to let the clients access
+ * trusted services in the Trusted Execution Environment (TEE).
+ *
+ * The following assumptions must be true for the underlying IPC mechanism and the transport layer:
+ *     1. Both parties should be able to retrieve a non-spoofable identifier of the other party from
+ *        the transport layer (a.k.a transport ID or vM ID), which stays the same throughout a given
+ *        boot cycle of a pVM instance. This is important to prevent person-in-the-middle (PITM)
+ *        attacks and to authorize a new connection from a pVM instance based on an already
+ *        authenicated connection from the same pVM instance.
+ *
+ *     2. Each of AuthMgr FE and the AuthMgr BE should be able to hand over a connection that is
+ *        setup between them to another party so that such connection can be used for communication
+ *        between the two new parties subsequently. This is important to be able to handover an
+ *        authorized connection established between the AuthMgr FE and the AuthMgr BE to a client in
+ *        in a pVM instance and a trusted service in TEE respectively.
+ *
+ *     3. This API should be exposed over an IPC mechanism that supports statefull connections. This
+ *        is important for the AuthMgr FE to setup an authenicated connection once per boot cycle
+ *        and reuse it to authorize multiple client connections afterwards, if needed.
+ *
+ *      4. AuthMgr FE has a mechanism for discovering and establishing a connection to the trusted
+ *         AuthMgr BE. Based on this assumptionson, mutual authentication is not covered by this
+ *         API.
+ *
+ * The AuthMgr authorization protocol consists of two phases:
+ *     1. Phase 1 authenticates the AuthMgr FE to the AuthMgr BE via the first two methods of this
+ *        API: `initAuthentication` and `completeAuthentication`. At the end of the successful
+ *        excecution of phase 1, the AuthMgr FE and the AuthMgr BE have an authenticated connection
+ *        established between them. Phase 1 also enforces rollback protection on AuthMgr FE in
+ *        addition to authentication.
+ *
+ *        Authentication is performed by verifying the AuthMgr FE's signature on the challenge
+ *        issued by the AuthMgr BE. The public signing key of the AuthMgr FE is obtained from the
+ *        validated DICE certificate chain for verifying the signature. Rollback protection is
+ *        enforced by matching the DICE certificate chain against the stored DICE policy.
+ *        AuthMgr FE uses this authenticated connection throughout the boot cycle of the pVM to send
+ *        phase 2 requests to the AuthMgr BE. Therefore, phase 1 needs to be executed only once per
+ *        boot cycle of the pVM. AuthMgr BE should take measures to prevent any duplicate
+ *        authentication attempts from the same instance or from any impersonating instances.
+ *
+ *     2. Phase 2 authorizes a client in the pVM to access trusted service(s) in the TEE and
+ *        establishes a new connection between the client and the trusted service based on the trust
+ *        in the authenticated connection established in phase 1. The client and the trusted service
+ *        can communicate independently from the AuthMgr(s) after the successful execution of
+ *        phase 2 of the authorization protocol.
+ *
+ *        The AuthMgr FE first opens a new vsock connection to the AuthMgr BE and sends a one-time
+ *        token over that connection. The AuthMgr FE then invokes the third method of this API
+ *        (`authorizeAndConnectClientToTrustedService`) on the authenticated connection established
+ *        with the AuthMgr BE in phase 1. Rollback protection is enforced on the client by matching
+ *        the client's DICE certificate against the stored DICE policy. The new connection is
+ *        authorized by matching the token sent over the new connection and the token sent over the
+ *        authenicated connection.
+ *
+ * AuthMgr BE should make sure that "use-after-destroy" threats are prevented in the implementation
+ * of this authorization protocol. This means that even if a client/pVM instance is created with the
+ * same identifier(s) of a deleted client/pVM instance, the new client should not be able to access
+ * the deleted client's secrets/resources created in the trusted services. The following
+ * requirements should be addressed in order to ensure this:
+ * 1) Each client should be identified by a unique identifier at the AuthMgr BE. The uniqueness
+ *    should be guaranteed across factory resets.
+ * 2) The client's unique identifier should be used when constructing the file path to store the
+ *    client's context, including the client's DICE policy, in the AuthMgr BE's secure storage.
+ * 3) The client's unique identifier should be conveyed to the trusted service(s) that the client
+ *    accesses, when an authorized connection is setup between the client and the trusted service in
+ *    phase 2. The trusted service(s) should mix in this unique client identifier when providing the
+ *    critical services to the clients (e.g. deriving HW-backed keys by the HWCrypto service,
+ *    storing data by the SecureStorage service).
+ *
+ * An example approach to build a unique identifier for a client is as follows:
+ * The AuthMgr BE stores a `global sequence number` in the secure storage that does not get
+ * wiped upon factory reset. Everytime the AuthMgr BE sees a new instance or a client, it assigns
+ * the current `global sequence number` as the unique sequence number of the instance or the client
+ * and increments the `global sequence number`.

+     * When the AuthMgr FE receives a request from a client to access a trusted service, the
+     * AuthMgr FE first creates a new (out-of-band) connection with the AuthMgr BE and sends a
+     * one-time cryptographic token of 32 bytes over that new connection.
+     *
+     * The AuthMgr FE then invokes this method on the authenticated connection established with the

+     * underlying connection of this method call is already authenticated.
+     *
+     * The AuthMgr FE acts as the DICE manager for all the clients in the pVM and generates the DICE
+     * leaf certificate and the DICE leaf policy for the client, which are sent in the input:
+     * `clientDiceArtifacts`.
+     *
+     * The AuthMgr BE matches the client's DICE leaf certificate to the client's DICE policy.
+     * If this is the first invocation of this method in the lifetime of the client, the AuthMgr BE
+     * stores the client's DICE policy in the secure storage as part of the client's context, upon
+     * successful matching of the DICE certificate to the policy. The file path for the storage of
+     * the client's context should be constructed using the unique id assigned to the pVM instance
+     * by the AuthMgr BE (e.g. instance sequence number)  and the client ID. There is no use
+     * case for deleting a client context or a pVM context created in the secure storage, for the
+     * first version of this API, outside of the factory reset. In the future, we expect to
+     * expose APIs for those tasks.
+     *
+     * In the subsequent invocations of this method, the AuthMgr BE matches the given DICE leaf
+     * certificate to the stored DICE policy in order to enforce rollback protection. If that
+     * succeeds and if the given DICE policy is different from the stored DICE policy, the AuthMgr
+     * BE replaces the stored DICE policy with the given DICE policy.
+     *
+     * If the same client requests multiple trusted services or connects to the same trusted service
+     * multiple times during the same boot cycle of the pVM instance, it is recommended to validate
+     * the client's DICE artifacts only once for a given client as an optimization.
+     *
+     * The AuthMgr BE keeps track of the aforementioned new connections that are pending
+     * authorization along with the tokens sent over them and the transport ID of the pVM instance
+     * which created those connections.
+     *
+     * The AuthMgr FE sends the same token that was sent over an aforementioned new connection
+     * in the input: `token` of this method call, in order to authorize the new connection, based on
+     * the trust in the authenticated connection established in phase 1.
+     *
+     * Once the validation of the client's DICE artifacts is completed, the AuthMgr BE retrieves the
+     * pending new connection to be authorized, which is associated with a token that matches the
+     * token sent in this method call and a transport ID that matches the transport ID associated
+     * with the connection underlying this method call.
+     *
+     * Next the AuthMgr BE connects to the trusted service requested by the client in order to
+     * handover the new authorized connection to the trusted service. Once the connection
+     * handover is successful, the AuthMgr BE returns OK to the AuthMgr FE. Then the AuthMgr FE
+     * returns to the client a handle to the new connection (created at the beginning of phase 2).
+     * At this point, an authorized connection is setup between the client and the trusted service,

+# IHDCPAuthControl as a Trusted HAL service
+
+IHDCPAuthControl is expected to be a service implemented in a TEE.
+We provide a default reference implementation and its integration in Trusty
+as an example.
+
+The VTS test for a Trusted HAL service ought to run in the VM.
+We provide an integration of the VTS test in a Trusty VM,
+and later in a Microdroid VM (b/380632474).
+
+This interface shall not be exposed to the host and thus shall be part of
+the list of excluded interfaces from
+[compatibility_matrices/exclude/fcm_exclude.cpp](../../../compatibility_matrices/exclude/fcm_exclude.cpp)
+
+## 1. Mock Implementation
+
+The mock implementation under default/src/lib.rs is expected to be integrated in a
+TEE. For AOSP testing we offer two virtual device testing options:
+
+- Cuttlefish AVD, where the reference implementation is integrated in an AVF VM, emulating a TEE.
+- Trusty QEMU AVD, where the reference implementation is integrated in a Trusty TEE image (executed in secure world)
+
+### 1.1. Cuttlefish: Integrate in an AVF HAL pVM (Trusty)
+
+In Cuttlefish, we emulate a TEE with an AVF Trusty pVM.
+The VM2TZ IPC is emulated with a vsock port forward utility (b/379582767).
+
+Until vsock port forwarding is supported, the trusty_test_vm is used temporarily.
+(VTS tests and HAL implementation will be in same pVM).
+
+TODO: complete when trusty_hal_vm is created
+
+In order to add the mock HdcpAuthControlService to the trusty_test_vm, make sure
+that `hardware/interfaces/security/see/hdcp/default` is added to the
+trusty_test_vm makefile, by adding it to
+[trusty/device/x86/generic-x86_64/project/generic-x86_64-inc.mk](../../../../../trusty/device/x86/generic-x86_64/project/generic-x86_64-inc.mk)
+
+### 1.2. Trusty QEMU AVD: Integrate as a TA in Trusty TEE
+
+In order to add the mock HdcpAuthControlService to the Trusty TEE, make sure
+that `hardware/interfaces/security/see/hdcp/default` is added to
+[trusty/device/arm/generic-arm64/project/generic-arm-inc.mk](../../../../../trusty/device/arm/generic-arm64/project/generic-arm-inc.mk)
+
+
+## 2. VTS Tests
+
+IHdcpAuthControl service is expected to only be exposed to AVF pVM.
+
+The VTS tests shall verify:
+
+- IHdcpAuthControl cannot be accessed from the Android Host:
+
+   see [aidl/vts/src/host_test.rs](aidl/vts/host_test.rs)
+
+- IHdcpAuthControl can be accessed from an AVF pVM:
+
+   see [aidl/vts/src/vm_test.rs](aidl/vts/src/vm_test.rs)
+   see [aidl/vts/AndroidTest.xml](aidl/vts/AndroidTest.xml)
+
+
+To integrate the VTS test in the trusty_test_vm:
+
+1.
+1. add the test to [hardware/interfaces/security/see/usertests-rust-inc.mk](../usertests-rust-inc.mk)

+// 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
