 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

+# 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.

+## 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
+

+# 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.

+# 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

+# 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

+// 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.

+
+// The AudioPolicyInterface and AudioPolicyClientInterface classes define the communication
+// interfaces between the platform specific audio policy manager and Android generic audio policy
+// manager. The platform specific audio policy manager must implement methods of the
+// AudioPolicyInterface class. This implementation makes use of the AudioPolicyClientInterface to
+// control the activity and configuration of audio input and output streams.
+//
+// The platform specific audio policy manager is in charge of the audio routing and volume control
+// policies for a given platform.
+// The main roles of this module are:
+//   - keep track of current system state (removable device connections, phone state, user
+//   requests...). System state changes and user actions are notified to audio policy manager with
+//   methods of the AudioPolicyInterface.
+//   - process getOutput() queries received when AudioTrack objects are created: Those queries
+//   return a handler on an output that has been selected, configured and opened by the audio policy
+//   manager and that must be used by the AudioTrack when registering to the AudioFlinger with the
+//   createTrack() method. When the AudioTrack object is released, a putOutput() query is received
+//   and the audio policy manager can decide to close or reconfigure the output depending on other
+//   streams using this output and current system state.
+//   - similarly process getInput() and putInput() queries received from AudioRecord objects and
+//   configure audio inputs.
+//   - process volume control requests: the stream volume is converted from an index value (received
+//   from UI) to a float value applicable to each output as a function of platform specific settings
+//   and current output route (destination device). It also make sure that streams are not muted if
+//   not allowed (e.g. camera shutter sound in some countries).
+//
+// The platform specific audio policy manager is provided as a shared library by platform vendors
+// (as for libaudio.so) and is linked with libaudioflinger.so

+// When connected the scan results shall be reported only if the score of any network in the scan
+// is greater than that of the currently connected BSSID.

+ * - when capturing a bug report, framework will indicate to driver that all the data

+ * The data uploaded by driver will be stored by framework in separate files, with one stream

+// 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. 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.
