 Directory structure of the audio HAL related code.
 
-Run `common/all-versions/copyHAL.sh` to create a new version of the audio HAL
-based on an existing one.
+## Directory Structure for AIDL audio HAL
 
-## Directory Structure
+The AIDL version is located inside `aidl` directory. The tree below explains
+the role of each subdirectory:
+
+* `aidl_api` — snapshots of the API created each Android release. Every
+  release, the current version of the API becomes "frozen" and gets assigned
+  the next version number. If the API needs further modifications, they are
+  made on the "current" version. After making modifications, run
+  `m <package name>-update-api` to update the snapshot of the "current"
+  version.
+* `android/hardware/audio/common` — data structures and interfaces shared
+  between various HALs: BT HAL, core and effects audio HALs.
+* `android/hardware/audio/core` — data structures and interfaces of the
+  core audio HAL.
+* `default` — the default, reference implementation of the audio HAL service.
+* `vts` — VTS tests for the AIDL HAL.
+
+## Directory Structure for HIDL audio HAL
+
+Run `common/all-versions/copyHAL.sh` to create a new version of the HIDL audio
+HAL based on an existing one. Note that this isn't possible since Android T
+release. Android U and above uses AIDL audio HAL.
 
 * `2.0` — version 2.0 of the core HIDL API. Note that `.hal` files
   can not be moved into the `core` directory because that would change

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

+// with such a backward incompatible change, it has a high risk of breaking

+     *    allowed by the audio policy.
+     *
+     * Other notes:
+     * 1. In case of AudioControl  service restart or resume, the implementations MUST
+     *    issue an immediate callback following registration.
+     * 2. In case of client restart, the AudioControl service MUST clear all stale

- * Vehicle Areas
+ * List of different supported area types for vehicle properties.
  * Used to construct property IDs in the VehicleProperty enum.
  *
- * Some properties may be associated with particular vehicle areas. For
- * example, VehicleProperty:DOOR_LOCK property must be associated with
- * particular door, thus this property must be marked with
- * VehicleArea:DOOR flag.
+ * Some properties may be associated with particular areas in the vehicle. For example,
+ * VehicleProperty#DOOR_LOCK property must be associated with a particular door, thus this property
+ * must be of the VehicleArea#DOOR area type.
  *
- * Other properties may not be associated with particular vehicle area.
- * These kinds of properties must have VehicleArea:GLOBAL flag.
+ * Other properties may not be associated with a particular area in the vehicle. These kinds of
+ * properties must be of the VehicleArea#GLOBAL area type.
  *
- * [Definition] Area: An area represents a unique element of an AreaType.
- *   For instance, if AreaType is WINDOW, then an area may be FRONT_WINDSHIELD.
- *
- * [Definition] AreaID: An AreaID is a combination of one or more areas,
- *   and is represented using a bitmask of Area enums. Different AreaTypes may
- *   not be mixed in a single AreaID. For instance, a window area cannot be
- *   combined with a seat area in an AreaID.
- *
- * Rules for mapping a zoned property to AreaIDs:
- *  - A property must be mapped to an array of AreaIDs that are impacted when
- *    the property value changes.
- *  - Each element in the array must represent an AreaID, in which the
- *    property value can only be changed together in all the areas within
- *    the AreaID and never independently. That is, when the property value
- *    changes in one of the areas in an AreaID in the array, then it must
- *    automatically change in all other areas in the AreaID.
- *  - The property value must be independently controllable in any two
- *    different AreaIDs in the array.
- *  - An area must only appear once in the array of AreaIDs. That is, an
- *    area must only be part of a single AreaID in the array.
- *
- * [Definition] Global Property: A property that applies to the entire car
- *   and is not associated with a specific area. For example, FUEL_LEVEL,
- *   HVAC_STEERING_WHEEL_HEAT.
- *
- * Rules for mapping a global property to AreaIDs:
- *  - A global property must not be mapped to AreaIDs.

-// 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.

-     * HVAC Properties
-     *
-     * Additional rules for mapping a zoned HVAC property (except
-     * HVAC_MAX_DEFROST_ON) to AreaIDs:
-     *  - Every seat in VehicleAreaSeat that is available in the car, must be
-     *    part of an AreaID in the AreaID array.
-     *
-     * Example 1: A car has two front seats (ROW_1_LEFT, ROW_1_RIGHT) and three
-     *  back seats (ROW_2_LEFT, ROW_2_CENTER, ROW_2_RIGHT). There are two
-     *  temperature control units -- driver side and passenger side.
-     *   - A valid mapping set of AreaIDs for HVAC_TEMPERATURE_SET would be a
-     *     two element array:
-     *      - ROW_1_LEFT  | ROW_2_LEFT
-     *      - ROW_1_RIGHT | ROW_2_CENTER | ROW_2_RIGHT
-     *   - An alternative mapping for the same hardware configuration would be:
-     *      - ROW_1_LEFT  | ROW_2_CENTER | ROW_2_LEFT
-     *      - ROW_1_RIGHT | ROW_2_RIGHT
-     *  The temperature controllers are assigned to the seats which they
-     *  "most influence", but every seat must be included exactly once. The
-     *  assignment of the center rear seat to the left or right AreaID may seem
-     *  arbitrary, but the inclusion of every seat in exactly one AreaID ensures
-     *  that the seats in the car are all expressed and that a "reasonable" way
-     *  to affect each seat is available.
-     *
-     * Example 2: A car has three seat rows with two seats in the front row (ROW_1_LEFT,
-     *  ROW_1_RIGHT) and three seats in the second (ROW_2_LEFT, ROW_2_CENTER,
-     *  ROW_2_RIGHT) and third rows (ROW_3_LEFT, ROW_3_CENTER, ROW_3_RIGHT). There
-     *  are three temperature control units -- driver side, passenger side, and rear.
-     *   - A reasonable way to map HVAC_TEMPERATURE_SET to AreaIDs is a three

-     *     - ROW_1_LEFT
-     *     - ROW_1_RIGHT

-     * This property is called by the Android system when it initializes and it lets the HAL

-     * This request is made by setting a VehiclePropValue (defined by InitialUserInfoRequest),

-     * If the HAL doesn't respond after some time (defined by the Android system), the Android
-     * system will proceed as if HAL returned a response of action
-     * InitialUserInfoResponseAction:DEFAULT.
-     *
-     * For example, on first boot, the request could be:
-     *
-     * int32[0]: 42  // request id (arbitrary number set by Android system)
-     * int32[1]: 1   // InitialUserInfoRequestType::FIRST_BOOT

-     * int32[6]: 1   // flags of user #0  (usersInfo.existingUsers[0].flags)
-     *
-     * And if the HAL want to respond with the creation of an admin user called "Owner", the

-     *
-     * int32[0]: 42      // must match the request id from the request

-     * (optional) system locales for the user to be created (in this case, it's empty, meaning it
-     * will use Android's default value), while the second value is the (also optional) name of the

-     * parameter), as defined below.
-     *
-     * 1.LEGACY_ANDROID_SWITCH
-     * -----------------------
-     *
-     * Called by the Android System to indicate the Android user is about to change, when the change
-     * request was made in a way that is not integrated with the HAL (for example, through
-     * adb shell am switch-user).
-     *
-     * The HAL can switch its internal user once it receives this request, but it doesn't need to
-     * reply back to the Android System. If its internal user cannot be changed for some reason,
-     * then it must wait for the SWITCH_USER(type=ANDROID_POST_SWITCH) call to recover
-     * (for example, it could issue a SWITCH_USER(type=VEHICLE_REQUEST) to switch back to
-     * the previous user), but ideally it should never fail (as switching back could result in a
-     * confusing experience for the end user).
-     *
-     * For example, if the system have users (0, 10, 11) and it's switching from 0 to 11 (where none
-     * of them have any special flag), the request would be:
-     *
-     * int32[0]:  42  // request id
-     * int32[1]:  1   // SwitchUserMessageType::LEGACY_ANDROID_SWITCH
-     * int32[2]:  11  // target user id
-     * int32[3]:  0   // target user flags (none)
-     * int32[4]:  10  // current user
-     * int32[5]:  0   // current user flags (none)
-     * int32[6]:  3   // number of users
-     * int32[7]:  0   // user #0 (Android user id 0)
-     * int32[8]:  0   // flags of user #0 (none)
-     * int32[9]:  10  // user #1 (Android user id 10)
-     * int32[10]: 0   // flags of user #1 (none)
-     * int32[11]: 11  // user #2 (Android user id 11)
-     * int32[12]: 0   // flags of user #2 (none)
-     *
-     * 2.ANDROID_SWITCH
-     * ----------------
-     * Called by the Android System to indicate the Android user is about to change, but Android
-     * will wait for the HAL's response (up to some time) before proceeding.
-     *
-     * The HAL must switch its internal user once it receives this request, then respond back to
-     * Android with a SWITCH_USER(type=VEHICLE_RESPONSE) indicating whether its internal
-     * user was switched or not (through the SwitchUserStatus enum).
-     *
-     * For example, if Android has users (0, 10, 11) and it's switching from 10 to 11 (where
-     * none of them have any special flag), the request would be:
-     *
-     * int32[0]:  42  // request id
-     * int32[1]:  2   // SwitchUserMessageType::ANDROID_SWITCH
-     * int32[2]:  11  // target user id
-     * int32[3]:  0   // target user flags (none)
-     * int32[4]:  10  // current user
-     * int32[5]:  0   // current user flags (none)
-     * int32[6]:  3   // number of users
-     * int32[7]:  0   // 1st user (user 0)
-     * int32[8]:  1   // 1st user flags (SYSTEM)
-     * int32[9]:  10  // 2nd user (user 10)
-     * int32[10]: 0   // 2nd user flags (none)
-     * int32[11]: 11  // 3rd user (user 11)
-     * int32[12]: 0   // 3rd user flags (none)
-     *
-     * If the request succeeded, the HAL must update the property with:
-     *
-     * int32[0]: 42  // request id
-     * int32[1]: 3   // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
-     * int32[2]: 1   // status = SwitchUserStatus::SUCCESS
-     *
-     * But if it failed, the response would be something like:
-     *
-     * int32[0]: 42   // request id
-     * int32[1]: 3    // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
-     * int32[2]: 2    // status = SwitchUserStatus::FAILURE
-     * string: "108-D'OH!" // OEM-specific error message
-     *
-     * 3.VEHICLE_RESPONSE
-     * ------------------
-     * Called by the HAL to indicate whether a request of type ANDROID_SWITCH should proceed or
-     * abort - see the ANDROID_SWITCH section above for more info.
-     *
-     * 4.VEHICLE_REQUEST
-     * ------------------
-     * Called by the HAL to request that the current foreground Android user is switched.
-     *
-     * This is useful in situations where Android started as one user, but the vehicle identified
-     * the driver as another user. For example, user A unlocked the car using the key fob of user B;
-     * the INITIAL_USER_INFO request returned user B, but then a face recognition subsubsystem
-     * identified the user as A.
-     *
-     * The HAL makes this request by a property change event (passing a negative request id), and
-     * the Android system will response by issue an ANDROID_POST_SWITCH call which the same
-     * request id.
-     *
-     * For example, if the current foreground Android user is 10 and the HAL asked it to switch to
-     * 11, the request would be:
-     *
-     * int32[0]: -108  // request id
-     * int32[1]: 4     // messageType = SwitchUserMessageType::VEHICLE_REQUEST
-     * int32[2]: 11    // Android user id
-     *
-     * If the request succeeded and Android has 3 users (0, 10, 11), the response would be:
-     *
-     * int32[0]: -108 // request id
-     * int32[1]:  5   // messageType = SwitchUserMessageType::ANDROID_POST_SWITCH
-     * int32[2]:  11  // target user id
-     * int32[3]:  0   // target user id flags (none)
-     * int32[4]:  11  // current user
-     * int32[5]:  0   // current user flags (none)
-     * int32[6]:  3   // number of users
-     * int32[7]:  0   // 1st user (user 0)
-     * int32[8]:  0   // 1st user flags (none)
-     * int32[9]:  10  // 2nd user (user 10)
-     * int32[10]: 4   // 2nd user flags (none)
-     * int32[11]: 11  // 3rd user (user 11)
-     * int32[12]: 3   // 3rd user flags (none)
-     *
-     * Notice that both the current and target user ids are the same - if the request failed, then
-     * they would be different (i.e, target user would be 11, but current user would still be 10).
-     *
-     * 5.ANDROID_POST_SWITCH
-     * ---------------------
-     * Called by the Android System after a request to switch a user was made.
-     *
-     * This property is called after switch requests of any type (i.e., LEGACY_ANDROID_SWITCH,
-     * ANDROID_SWITCH, or VEHICLE_REQUEST) and can be used to determine if the request succeeded or
-     * failed:
-     *
-     * 1. When it succeeded, it's called when the Android user is in the unlocked state and the
-     *    value of the current and target users ids in the response are the same. This would be
-     *    equivalent to receiving an Intent.ACTION_USER_UNLOCKED in an Android app.
-     * 2. When it failed it's called right away and the value of the current and target users ids
-     *    in the response are different (as the current user didn't change to the target).
-     * 3. If a new switch request is made before the HAL responded to the previous one or before
-     *    the user was unlocked, then the ANDROID_POST_SWITCH request is not made. For example,
-     *    the driver could accidentally switch to the wrong user which has lock credentials, then
-     *    switch to the right one before entering the credentials.
-     *
-     * The HAL can update its internal state once it receives this request, but it doesn't need to
-     * reply back to the Android System.
-     *
-     * Request: the first N values as defined by INITIAL_USER_INFO (where the request-specific
-     * value at index 1 is SwitchUserMessageType::ANDROID_POST_SWITCH), then 2 more values for the
-     * target user id (i.e., the Android user id that was requested to be switched to) and its flags
-     * (as defined by  UserFlags).
-     *
-     * Response: none.
-     *
-     * Example: see VEHICLE_REQUEST section above.

-     * Property used to associate (or query the association) the current user with vehicle-specific
-     * identification mechanisms (such as key FOB).
-     *
-     * This is an optional user management property - the OEM could still support user management
-     * without defining it. In fact, this property could be used without supporting the core
-     * user-related functions described on INITIAL_USER_INFO.
-     *
-     * To query the association, the Android system gets the property, passing a VehiclePropValue
-     * containing the types of associations are being queried, as defined by
-     * UserIdentificationGetRequest. The HAL must return right away, returning a VehiclePropValue
-     * with a UserIdentificationResponse. Notice that user identification should have already
-     * happened while system is booting up and the VHAL implementation should only return the
-     * already identified association (like the key FOB used to unlock the car), instead of starting
-     * a new association from the get call.
-     *
-     * To associate types, the Android system sets the property, passing a VehiclePropValue
-     * containing the types and values of associations being set, as defined by the
-     * UserIdentificationSetRequest. The HAL will then use a property change event (whose
-     * VehiclePropValue is defined by UserIdentificationResponse) indicating the current status of
-     * the types after the request.
-     *
-     * For example, to query if the current user (10) is associated with the FOB that unlocked the
-     * car and a custom mechanism provided by the OEM, the request would be:
-     *
-     * int32[0]: 42  // request id
-     * int32[1]: 10  (Android user id)
-     * int32[2]: 0   (Android user flags)
-     * int32[3]: 2   (number of types queried)
-     * int32[4]: 1   (1st type queried, UserIdentificationAssociationType::KEY_FOB)
-     * int32[5]: 101 (2nd type queried, UserIdentificationAssociationType::CUSTOM_1)
-     *
-     * If the user is associated with the FOB but not with the custom mechanism, the response would
-     * be:
-     *
-     * int32[0]: 42  // request id
-     * int32[1]: 2   (number of associations in the response)
-     * int32[2]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB)
-     * int32[3]: 2   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)
-     * int32[4]: 101 (2st type: UserIdentificationAssociationType::CUSTOM_1)
-     * int32[5]: 4   (2nd value: UserIdentificationAssociationValue::NOT_ASSOCIATED_ANY_USER)
-     *
-     * Then to associate the user with the custom mechanism, a set request would be made:
-     *
-     * int32[0]: 43  // request id
-     * int32[1]: 10  (Android user id)
-     * int32[2]: 0   (Android user flags)
-     * int32[3]: 1   (number of associations being set)
-     * int32[4]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1)
-     * int32[5]: 1   (1st value: UserIdentificationAssociationSetValue::ASSOCIATE_CURRENT_USER)
-     *
-     * If the request succeeded, the response would be simply:
-     *
-     * int32[0]: 43  // request id
-     * int32[1]: 1   (number of associations in the response)
-     * int32[2]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1)
-     * int32[3]: 1   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)
-     *
-     * Notice that the set request adds associations, but doesn't remove the existing ones. In the
-     * example above, the end state would be 2 associations (FOB and CUSTOM_1). If we wanted to
-     * associate the user with just CUSTOM_1 but not FOB, then the request should have been:
-     *
-     * int32[0]: 43  // request id
-     * int32[1]: 10  (Android user id)
-     * int32[2]: 2   (number of types set)
-     * int32[3]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB)
-     * int32[4]: 2   (1st value: UserIdentificationAssociationValue::DISASSOCIATE_CURRENT_USER)
-     * int32[5]: 101 (2nd type: UserIdentificationAssociationType::CUSTOM_1)

+# 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` 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@V1-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.

+# Property Configuration Files
+
+Each JSON file in this folder is a property configuration file for reference
+Vehicle HAL. They contain VehiclePropConfig information along with initial

+
+Each JSON file must be in a schema like the following example:
+(The comment starting with "//" is for documentation only and must be removed
+from the actual JSON file. The "comment" field is used for comment in the
+actual JSON file and will be ignored by the parser)

+
+## JSON Number-type Field Values
+
+For number type field values, they can either be defined as a numeric number,
+e.g., `{"minInt32Value": 1}` or be defined as a string which represents a
+defined constant value, e.g.,
+`{"property": "VehicleProperty::INFO_FUEL_CAPACITY"}`.
+
+For constant values, they must be a string in the format of `XXX::XXX`, where
+the field before `::` is the constant type, and the field after `::` is the
+variable name.
+
+We support the following constant types:
+
+* VehiclePropertyAccess
+
+* VehiclePropertyChangeMode
+
+* VehicleGear
+
+* VehicleAreaWindow
+
+* VehicleOilLevel
+
+* VehicleUnit
+
+* VehicleSeatOccupancyState
+
+* VehicleHvacFanDirection
+
+* VehicleApPowerStateReport
+
+* VehicleTurnSignal
+
+* VehicleVendorPermission
+
+* EvsServiceType
+
+* EvsServiceState
+
+* EvConnectorType
+
+* VehicleProperty
+
+* GsrComplianceRequirementType
+
+* VehicleIgnitionState
+
+* FuelType
+
+* AutomaticEmergencyBrakingState
+
+* ForwardCollisionWarningState
+
+* BlindSpotWarningState
+
+* LaneDepartureWarningState
+
+* LaneKeepAssistState
+
+* LaneCenteringAssistCommand
+
+* LaneCenteringAssistState
+
+* ErrorState
+
+* WindshieldWipersState
+
+* WindshieldWipersSwitch
+
+* Constants
+
+Every constant type except "Constants" corresponds to a enum defined in Vehicle
+HAL interfac. E.g. "VehicleProperty" corresponds to the enums defined in
+"VehicleProperty.aidl".
+
+"Constants" type refers to the constant variables defined in the paresr.
+Specifically, the "CONSTANTS_BY_NAME" map defined in "JsonConfigLoader.cpp".

+# 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` 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.

+# Utility classes for VHAL implementation
+---
+
+This directory stores utility classes for VHAL implementation. Vendor
+implementation could use utility classes from `common` folder in their
+VHAL implementation.
+
+## common
+
+Defines common utility libraries.
+
+### ConcurrentQueue
+
+Provides a thread-safe concurrent queue object. Useful for adding object to
+a queue in one thread (usually binder thread) and handle the objects in a
+separate handler thread.
+
+### ParcelableUtils
+
+Provides functions to convert between a regular parcelable and a
+`LargeParcelabe`.
+
+A `LargeParcelable` is a parcelable that marshals the payload
+into a shared memory file if the payload is too large to pass across binder.
+It is used to pass large data across binder. Before sending the data, VHAL
+impl should convert a regular parcelabe to a `LargeParcelable`. After receving
+data, VHAL impl should convert a `LargeParcelable` back to regular parcelabe.
+
+### PendingRequestPool
+
+Defines A class for managing pending requests and automatically call timeout
+callback if the request timed-out.
+
+### PropertyUtils
+
+Defines some useful constants.
+
+### RecurrentTimer
+
+Defines a thread-safe recurrent timer that can call a function periodically.
+
+### VehicleHalTypes
+
+Provides a header file that includes many commonly used header files. Useful
+when you are using multiple types defined in VHAL interface.
+
+### VehicleObjectPool
+
+Defines a reusable in-memory pool for `VehiclePropValue`.
+
+### VehiclePropertyStore
+
+Defines an in-memory map for storing vehicle properties. Allows easier insert,
+delete and lookup.
+
+### VehicleUtils
+
+Defines many useful utility functions.
+
+## test
+
+Defines utility libraries for test only.

+     *     two element array:
+     *      - ROW_1_LEFT  | ROW_2_LEFT
+     *      - ROW_1_RIGHT | ROW_2_CENTER | ROW_2_RIGHT
+     *   - An alternative mapping for the same hardware configuration would be:
+     *      - ROW_1_LEFT  | ROW_2_CENTER | ROW_2_LEFT
+     *      - ROW_1_RIGHT | ROW_2_RIGHT
+     *  The temperature controllers are assigned to the seats which they
+     *  "most influence", but every seat must be included exactly once. The
+     *  assignment of the center rear seat to the left or right AreaID may seem
+     *  arbitrary, but the inclusion of every seat in exactly one AreaID ensures
+     *  that the seats in the car are all expressed and that a "reasonable" way
+     *  to affect each seat is available.
+     *
+     * Example 2: A car has three seat rows with two seats in the front row (ROW_1_LEFT,
+     *  ROW_1_RIGHT) and three seats in the second (ROW_2_LEFT, ROW_2_CENTER,
+     *  ROW_2_RIGHT) and third rows (ROW_3_LEFT, ROW_3_CENTER, ROW_3_RIGHT). There
+     *  are three temperature control units -- driver side, passenger side, and rear.
+     *   - A reasonable way to map HVAC_TEMPERATURE_SET to AreaIDs is a three
+     *     element array:
+     *     - ROW_1_LEFT
+     *     - ROW_1_RIGHT
+     *     - ROW_2_LEFT | ROW_2_CENTER | ROW_2_RIGHT | ROW_3_LEFT | ROW_3_CENTER | ROW_3_RIGHT
+     *
+     * Example 3: A car has two front seats (ROW_1_LEFT, ROW_1_RIGHT) and three
+     *  back seats (ROW_2_LEFT, ROW_2_CENTER, ROW_2_RIGHT). Suppose the car
+     *  supports HVAC_AUTO_ON for just the two front seats.
+     *   - A valid mapping set of AreaIDs for HVAC_AUTO_ON would be:
+     *      - ROW_1_LEFT | ROW_1_RIGHT
+     *   - If HVAC_AUTO_ON had two separate control units for the driver side

+     * The HAL can switch its internal user once it receives this request, but it doesn't need to
+     * reply back to the Android System. If its internal user cannot be changed for some reason,
+     * then it must wait for the SWITCH_USER(type=ANDROID_POST_SWITCH) call to recover
+     * (for example, it could issue a SWITCH_USER(type=VEHICLE_REQUEST) to switch back to
+     * the previous user), but ideally it should never fail (as switching back could result in a
+     * confusing experience for the end user).
+     *
+     * For example, if the system have users (0, 10, 11) and it's switching from 0 to 11 (where none
+     * of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  1   // SwitchUserMessageType::LEGACY_ANDROID_SWITCH

+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // user #0 (Android user id 0)
+     * int32[8]:  0   // flags of user #0 (none)

+     * The HAL must switch its internal user once it receives this request, then respond back to
+     * Android with a SWITCH_USER(type=VEHICLE_RESPONSE) indicating whether its internal
+     * user was switched or not (through the SwitchUserStatus enum).
+     *
+     * For example, if Android has users (0, 10, 11) and it's switching from 10 to 11 (where
+     * none of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  2   // SwitchUserMessageType::ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  1   // 1st user flags (SYSTEM)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 0   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 0   // 3rd user flags (none)
+     *
+     * If the request succeeded, the HAL must update the property with:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 3   // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 1   // status = SwitchUserStatus::SUCCESS
+     *
+     * But if it failed, the response would be something like:
+     *
+     * int32[0]: 42   // request id
+     * int32[1]: 3    // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 2    // status = SwitchUserStatus::FAILURE
+     * string: "108-D'OH!" // OEM-specific error message
+     *
+     * 3.VEHICLE_RESPONSE
+     * ------------------
+     * Called by the HAL to indicate whether a request of type ANDROID_SWITCH should proceed or
+     * abort - see the ANDROID_SWITCH section above for more info.
+     *
+     * 4.VEHICLE_REQUEST
+     * ------------------
+     * Called by the HAL to request that the current foreground Android user is switched.
+     *
+     * This is useful in situations where Android started as one user, but the vehicle identified
+     * the driver as another user. For example, user A unlocked the car using the key fob of user B;
+     * the INITIAL_USER_INFO request returned user B, but then a face recognition subsubsystem
+     * identified the user as A.
+     *
+     * The HAL makes this request by a property change event (passing a negative request id), and
+     * the Android system will response by issue an ANDROID_POST_SWITCH call which the same
+     * request id.
+     *
+     * For example, if the current foreground Android user is 10 and the HAL asked it to switch to
+     * 11, the request would be:
+     *
+     * int32[0]: -108  // request id
+     * int32[1]: 4     // messageType = SwitchUserMessageType::VEHICLE_REQUEST
+     * int32[2]: 11    // Android user id
+     *
+     * If the request succeeded and Android has 3 users (0, 10, 11), the response would be:
+     *
+     * int32[0]: -108 // request id
+     * int32[1]:  5   // messageType = SwitchUserMessageType::ANDROID_POST_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user id flags (none)
+     * int32[4]:  11  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  0   // 1st user flags (none)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 4   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 3   // 3rd user flags (none)
+     *
+     * Notice that both the current and target user ids are the same - if the request failed, then
+     * they would be different (i.e, target user would be 11, but current user would still be 10).
+     *
+     * 5.ANDROID_POST_SWITCH
+     * ---------------------
+     * Called by the Android System after a request to switch a user was made.
+     *
+     * This property is called after switch requests of any type (i.e., LEGACY_ANDROID_SWITCH,
+     * ANDROID_SWITCH, or VEHICLE_REQUEST) and can be used to determine if the request succeeded or
+     * failed:
+     *
+     * 1. When it succeeded, it's called when the Android user is in the unlocked state and the
+     *    value of the current and target users ids in the response are the same. This would be
+     *    equivalent to receiving an Intent.ACTION_USER_UNLOCKED in an Android app.
+     * 2. When it failed it's called right away and the value of the current and target users ids
+     *    in the response are different (as the current user didn't change to the target).
+     * 3. If a new switch request is made before the HAL responded to the previous one or before
+     *    the user was unlocked, then the ANDROID_POST_SWITCH request is not made. For example,
+     *    the driver could accidentally switch to the wrong user which has lock credentials, then
+     *    switch to the right one before entering the credentials.
+     *
+     * The HAL can update its internal state once it receives this request, but it doesn't need to
+     * reply back to the Android System.
+     *
+     * Request: the first N values as defined by INITIAL_USER_INFO (where the request-specific
+     * value at index 1 is SwitchUserMessageType::ANDROID_POST_SWITCH), then 2 more values for the
+     * target user id (i.e., the Android user id that was requested to be switched to) and its flags
+     * (as defined by  UserFlags).
+     *
+     * Response: none.
+     *
+     * Example: see VEHICLE_REQUEST section above.

+     * To query the association, the Android system gets the property, passing a VehiclePropValue

+     *
+     * For example, to query if the current user (10) is associated with the FOB that unlocked the
+     * car and a custom mechanism provided by the OEM, the request would be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 0   (Android user flags)

+     * int32[4]: 1   (1st type queried, UserIdentificationAssociationType::KEY_FOB)
+     * int32[5]: 101 (2nd type queried, UserIdentificationAssociationType::CUSTOM_1)
+     *
+     * If the user is associated with the FOB but not with the custom mechanism, the response would
+     * be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 2   (number of associations in the response)
+     * int32[2]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB)

+     * int32[5]: 4   (2nd value: UserIdentificationAssociationValue::NOT_ASSOCIATED_ANY_USER)
+     *
+     * Then to associate the user with the custom mechanism, a set request would be made:
+     *
+     * int32[0]: 43  // request id
+     * int32[1]: 10  (Android user id)

+// 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.

+# Virtual Face HAL
+
+This is a virtual HAL implementation that is backed by system properties
+instead of actual hardware. It's intended for testing and UI development
+on debuggable builds to allow devices to masquerade as alternative device
+types and for emulators.
+
+## Device Selection
+
+You can either run the FakeFaceEngine on a [real device](#actual-device) or a [virtual device/cuttlefish](#getting-started-on-a-virtual-device-cuttlefish). This document should
+help you to get started on either one.
+
+After setting up a device, go ahead and try out [enrolling](#enrolling) & [authenticating](#authenticating)
+
+### Getting started on a Virtual Device (cuttlefish)
+
+
+Note, I'm running this via a cloudtop virtual device.
+
+1. Setup cuttlefish on cloudtop, See [this](https://g3doc.corp.google.com/company/teams/android/teampages/acloud/getting_started.md?cl=head) for more details.
+2. acloud create --local-image
+3. Enter in the shell command to disable hidl
+
+```shell
+$ adb root
+$ adb shell settings put secure com.android.server.biometrics.AuthService.hidlDisabled 1
+$ adb reboot
+```
+4. You should now be able to do fake enrollments and authentications (as seen down below)
+
+### Actual Device
+
+1. Modify your real devices make file (I.E. vendor/google/products/{YOUR_DEVICE}.mk)
+2. Ensure that there is no other face HAL that is being included by the device
+3. Add the following
+```
+PRODUCT_COPY_FILES += \
+    frameworks/native/data/etc/android.hardware.biometrics.face.xml:$(TARGET_COPY_OUT_PRODUCT)/etc/permissions/android.hardware.biometrics.face.xml
+
+PRODUCT_PACKAGES += \
+    android.hardware.biometrics.face-service.example \
+
+```
+4. Now build and flash m -j120 && flash
+5. Run the following commands
+
+```shell
+# This is a temporary workaround
+$ adb root
+$ adb shell setprop persist.vendor.face.virtual.type RGB
+$ adb shell setprop persist.vendor.face.virtual.strength strong
+$ adb shell locksettings set-pin 0000
+$ adb reboot
+```
+
+## Enrolling
+
+```shell
+# authenticar_id,bucket_id:duration:(true|false)....
+$ adb shell setprop vendor.face.virtual.next_enrollment 1,0:500:true,5:250:true,10:150:true,15:500:true
+$ adb shell am start -n com.android.settings/.biometrics.face.FaceEnrollIntroduction
+# If you would like to get rid of the enrollment, run the follwoing command
+$ adb shell setprop persist.vendor.face.virtual.enrollments \"\"
+```
+
+## Authenticating
+
+```shell
+# If enrollment hasn't been setup
+$ adb shell setprop persist.vendor.face.virtual.enrollments 1
+$ adb shell cmd face sync
+# After enrollment has been setup
+$ adb shell setprop vendor.face.virtual.operation_authenticate_duration 800
+$ adb shell setprop vendor.face.virtual.enrollment_hit 1
+# Power button press to simulate auth
+$ adb shell input keyevent 26
+```

+# Virtual Fingerprint HAL
+
+This is a virtual HAL implementation that is backed by system properties instead
+of actual hardware. It's intended for testing and UI development on debuggable
+builds to allow devices to masquerade as alternative device types and for
+emulators.
+
+## Supported Devices
+
+This HAL can be used on emulators, like cuttlefish, or on real devices. Add the
+following to your device's `.mk` file to include it:
+
+```
+PRODUCT_PACKAGES_DEBUG += android.hardware.biometrics.fingerprint-service.example
+```
+
+The virtual HAL will be ignored if a real HAL is also installed on the target
+device. Set the `biometric_virtual_enabled` settings and reboot the device to
+switch to the virtual HAL. Unset it and reboot again to switch back.
+
+## Getting Started
+
+First, set the type of sensor the device should use, enable the virtual
+extensions in the framework, and reboot.
+
+```shell
+$ adb root
+$ adb shell settings put secure biometric_virtual_enabled 1
+$ adb shell setprop persist.vendor.fingerprint.virtual.type rear
+$ adb reboot
+```
+
+### Enrollments
+
+Next, setup enrollments on the device. This can either be done through the UI,
+or via adb directly.
+
+#### Direct Enrollment
+
+To set enrollment directly without the UI:
+
+```shell
+$ adb root
+$ adb shell locksettings set-pin 0000
+$ adb shell setprop persist.vendor.fingerprint.virtual.enrollments 1
+$ adb shell cmd fingerprint sync
+```
+
+#### UI Enrollment
+
+1. Set pin
+      ```shell
+      $ adb shell locksettings set-pin 0000
+      ```
+2. Tee up the results of the enrollment before starting the process:
+
+      ```shell
+      $ adb shell setprop vendor.fingerprint.virtual.next_enrollment 1:100,100,100:true
+      ```
+
+3. Navigate to `Settings -> Security -> Fingerprint Unlock` and follow the
+   prompts.
+4. Verify the enrollments in the UI:
+
+      ```shell
+      $ adb shell getprop persist.vendor.fingerprint.virtual.enrollments
+      ```
+
+## Authenticate
+
+To authenticate successfully set the enrolled id that should succeed. Unset it
+or change the value to make authenticate operations fail:
+
+````shell
+$ adb shell setprop vendor.fingerprint.virtual.enrollment_hit 1
+````
+
+## Acquired Info Insertion
+
+Fingerprint image acquisition states at HAL are reported to framework via onAcquired() callback. The valid acquired state info for AIDL HAL include
+
+{UNKNOWN(0), GOOD(1), PARTIAL(2), INSUFFICIENT(3), SENSOR_DIRTY(4), TOO_SLOW(5), TOO_FAST(6), VENDOR(7), START(8), TOO_DARK(9), TOO_BRIGHT(10), IMMOBILE(11), RETRYING_CAPTURE(12)}
+
+Refer to [AcquiredInfo.aidl](../android/hardware/biometrics/fingerprint/AcquiredInfo.aidl) for details
+
+
+The states can be specified in sequence for the HAL operations involving fingerprint image captures, namely authenticate, enrollment and detectInteraction
+
+```shell
+$ adb shell setprop vendor.fingerprint.virtual.operation_authenticate_acquired 6,9,1
+$ adb shell setprop vendor.fingerprint.virtual.operation_detect_interaction_acquired 6,1
+$ adb shell setprop vendor.fingerprint.virtual.next_enrollment 2:1000-[5,1],500:true
+
+#next_enrollment format example:
+.---------------------- enrollment id (2)
+|   .------------------ the image capture 1 duration (1000ms)
+|   |   .--------------   acquired info first (TOO_SLOW)
+|   |   | .------------   acquired info second (GOOD)
+|   |   | |   .-------- the image capture 2 duration (500ms)
+|   |   | |   |   .---- enrollment end status (success)
+|   |   | |   |   |
+|   |   | |   |   |
+|   |   | |   |   |
+2:1000-[5,1],500:true
+```
+For vendor specific acquired info, acquiredInfo = 1000 + vendorAcquiredInfo
+
+## Error Insertion
+The valid error codes for AIDL HAL include
+
+{UNKNOWN(0), HW_UNAVAILABLE(1), UNABLE_TO_PROCESS(2), TIMEOUT(3), NO_SPACE(4), CANCELED(5), UNABLE_TO_REMOVE(6), VENDOR(7), BAD_CALIBRATION(8)}
+
+Refer to [Error.aidl](../android/hardware/biometrics/fingerprint/Error.aidl) for details
+
+
+There are many HAL operations which can result in errors, refer to [here](fingerprint.sysprop) file for details.
+
+```shell
+$ adb shell setprop vendor.fingerprint.virtual.operation_authenticate_error 8
+```
+For vendor specific error, errorCode = 1000 + vendorErrorCode
+
+## Latency Insertion
+Three HAL operations (authenticate, enrollment and detect interaction) latency can be optionally specified in multiple ways
+1. default latency is fixed at 400 ms if not specified via sysprop
+2. specify authenticate operation latency to 900 ms
+      ```shell adb shell setprop vendor.fingerprint.virtual.operation_authenticate_latency 900```
+3. specify authenticate operation latency between 600 to 1200 ms in unifrom distribution
+      ```shelladb shell setprop vendor.fingerprint.virtual.operation_authenticate_latency 600,1200```
+
+## Lockout
+To force the device into lockout state
+```shell
+$ adb shell setprop persist.vendor.fingerprint.virtual.lockout true
+```
+To test permanent lockout based on the failed authentication attempts (e.g. 7)
+```shell
+$ adb shell setprop persist.vendor.fingerprint.virtual.lockout_permanent_threshold 7
+$ adb shell setprop persist.vendor.fingerprint.virtual.lockout_enable true
+```
+To test timed lockout based on the failed authentication attempts (e.g. 8 seconds on 5 attempts)
+```shell
+$ adb shell setprop persist.vendor.fingerprint.virtual.lockout_timed_duration 8000
+$ adb shell setprop persist.vendor.fingerprint.virtual.lockout_timed_threshold 5
+$ adb shell setprop persist.vendor.fingerprint.virtual.lockout_enable true
+```
+
+## Reset all configurations to default
+The following command will reset virtual configurations (related system properties) to default value.
+```shell
+$ adb shell cmd android.hardware.biometrics.fingerprint.IFingerprint/virtual resetconfig
+$ adb reboot
+```
+
+## View HAL State
+
+To view all the properties of the HAL (see `fingerprint.sysprop` file for the API):
+
+```shell
+$ adb shell getprop | grep vendor.fingerprint.virtual
+```
+To dump virtual HAL internal data
+```shell
+adb shell dumpsys android.hardware.biometrics.fingerprint.IFingerprint/virtual
+```

+// 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.

+// 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.

+// 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.

-Vendor HAL Threading Model
-==========================
-The vendor HAL service has two threads:
-1. HIDL thread: This is the main thread which processes all the incoming HIDL
-RPC's.
-2. Legacy HAL event loop thread: This is the thread forked off for processing
-the legacy HAL event loop (wifi_event_loop()). This thread is used to process
-any asynchronous netlink events posted by the driver. Any asynchronous
-callbacks passed to the legacy HAL API's are invoked on this thread.
-
-Synchronization Concerns
-========================
-wifi_legacy_hal.cpp has a bunch of global "C" style functions to handle the
-legacy callbacks. Each of these "C" style function invokes a corresponding
-"std::function" version of the callback which does the actual processing.
-The variables holding these "std::function" callbacks are reset from the HIDL
-thread when they are no longer used. For example: stopGscan() will reset the
-corresponding "on_gscan_*" callback variables which were set when startGscan()
-was invoked. This is not thread safe since these callback variables are
-accesed from the legacy hal event loop thread as well.
-
-Synchronization Solution
-========================
-Adding a global lock seems to be the most trivial solution to the problem.
-a) All of the asynchronous "C" style callbacks will acquire the global lock
-before invoking the corresponding "std::function" callback variables.
-b) All of the HIDL methods will also acquire the global lock before processing
-(in hidl_return_util::validateAndCall()).
-
-Note: It's important that we only acquire the global lock for asynchronous
-callbacks, because there is no guarantee (or documentation to clarify) that the
-synchronous callbacks are invoked on the same invocation thread. If that is not
-the case in some implementation, we will end up deadlocking the system since the
-HIDL thread would have acquired the global lock which is needed by the
-synchronous callback executed on the legacy hal event loop thread.

-/* The chip may either have a single mode supporting any number of combinations,
- * or a fixed dual-mode (so it involves firmware loading to switch between
- * modes) setting. If there is a need to support more modes, it needs to be
- * implemented manually in WiFi HAL (see changeFirmwareMode in
- * WifiChip::handleChipConfiguration).
- *
- * Supported combinations are defined in device's makefile, for example:
- *    WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
- *    WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
- * What means:
- *    Interface concurrency combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
- *                             operations.
- *    Interface concurrency combination 2: 1 STA and 2 AP concurrent iface operations.
- *
- * For backward compatibility, the following makefile flags can be used to
- * generate combinations list:
- *  - WIFI_HIDL_FEATURE_DUAL_INTERFACE
- *  - WIFI_HIDL_FEATURE_DISABLE_AP
- *  - WIFI_HIDL_FEATURE_AWARE
- * However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
- * With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
- * two concurrency combinations:
- *    Interface Concurrency Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
- *                             concurrent iface operations.
- *    Interface Concurrency Combination 2: Will support 1 STA and 1 AP concurrent
- *                             iface operations.
- *
- * The only dual-mode configuration supported is for alternating STA and AP
- * mode, that may involve firmware reloading. In such case, there are 2 separate
- * modes of operation with 1 concurrency combination each:
- *    Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
- *                       concurrent iface operations.
- *    Mode 2 (AP mode): Will support 1 AP iface operation.
- *
- * If Aware is enabled, the concurrency combination will be modified to support either
- * P2P or NAN in place of just P2P.

+Vendor HAL Threading Model
+==========================
+The vendor HAL service has two threads:
+1. AIDL thread: This is the main thread which processes all the incoming AIDL
+RPC's.
+2. Legacy HAL event loop thread: This is the thread forked off for processing
+the legacy HAL event loop (wifi_event_loop()). This thread is used to process
+any asynchronous netlink events posted by the driver. Any asynchronous
+callbacks passed to the legacy HAL API's are invoked on this thread.
+
+Synchronization Concerns
+========================
+wifi_legacy_hal.cpp has a bunch of global "C" style functions to handle the
+legacy callbacks. Each of these "C" style functions invokes a corresponding
+"std::function" version of the callback which does the actual processing.
+The variables holding these "std::function" callbacks are reset from the AIDL
+thread when they are no longer used. For example: stopGscan() will reset the
+corresponding "on_gscan_*" callback variables which were set when startGscan()
+was invoked. This is not thread safe since these callback variables are
+accesed from the legacy hal event loop thread as well.
+
+Synchronization Solution
+========================
+Adding a global lock seems to be the most trivial solution to the problem.
+a) All of the asynchronous "C" style callbacks will acquire the global lock
+before invoking the corresponding "std::function" callback variables.
+b) All of the AIDL methods will also acquire the global lock before processing
+(in aidl_return_util::validateAndCall()).
+
+Note: It's important that we only acquire the global lock for asynchronous
+callbacks, because there is no guarantee (or documentation to clarify) that the
+synchronous callbacks are invoked on the same invocation thread. If that is not
+the case in some implementation, we will end up deadlocking the system since the
+AIDL thread would have acquired the global lock which is needed by the
+synchronous callback executed on the legacy hal event loop thread.

+/* The chip may either have a single mode supporting any number of combinations,
+ * or a fixed dual-mode (so it involves firmware loading to switch between
+ * modes) setting. If there is a need to support more modes, it needs to be
+ * implemented manually in WiFi HAL (see changeFirmwareMode in
+ * WifiChip::handleChipConfiguration).
+ *
+ * Supported combinations are defined in device's makefile, for example:
+ *    WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
+ *    WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
+ * What this means:
+ *    Interface concurrency combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
+ *                             operations.
+ *    Interface concurrency combination 2: 1 STA and 2 AP concurrent iface operations.
+ *
+ * For backward compatibility, the following makefile flags can be used to
+ * generate combinations list:
+ *  - WIFI_HIDL_FEATURE_DUAL_INTERFACE
+ *  - WIFI_HIDL_FEATURE_DISABLE_AP
+ *  - WIFI_HIDL_FEATURE_AWARE
+ * However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
+ * With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
+ * two concurrency combinations:
+ *    Interface Concurrency Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
+ *                             concurrent iface operations.
+ *    Interface Concurrency Combination 2: Will support 1 STA and 1 AP concurrent
+ *                             iface operations.
+ *
+ * The only dual-mode configuration supported is for alternating STA and AP
+ * mode, that may involve firmware reloading. In such case, there are 2 separate
+ * modes of operation with 1 concurrency combination each:
+ *    Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
+ *                       concurrent iface operations.
+ *    Mode 2 (AP mode): Will support 1 AP iface operation.
+ *
+ * If Aware is enabled, the concurrency combination will be modified to support either
+ * P2P or NAN in place of just P2P.
