 /**
- * 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.
-*/
+ * Note: This is not the same as areaId used in VehicleAreaConfig. E.g. for a global property, the
+ * property ID is of the VehicleArea#GLOBAL area type, however, the area ID must be 0.

+// 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 AudioPolicyInterface and AudioPolicyClientInterface classes define the communication

-// 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

-// Enhanced PNO feature is expected to be enabled all of the time (e.g. screen lit) and may thus

-// Therefore, it is acceptable for firmware to store a crc24, crc32 or other short hash of the SSID,
-// such that a low but non-zero probability of collision exist. With that scheme it should be
-// possible for firmware to keep an entry as small as 4 bytes for each pno network.
-// For instance, a firmware pn0 entry can be implemented in the form of:
-//          PNO ENTRY = crc24(3 bytes) | flags>>3 (5 bits) | auth flags(3 bits)
-//
-// No scans should be automatically performed by the chip. Instead all scan results from gscan
-// should be scored and the wifi_epno_handler on_network_found callback should be called with
-// the scan results.
-//
-// A PNO network shall be reported once, that is, once a network is reported by firmware
-// its entry shall be marked as "done" until framework calls wifi_set_epno_list again.
-// Calling wifi_set_epno_list shall reset the "done" status of pno networks in firmware.
-//
-// A network should only be considered found if its RSSI is above the minimum RSSI for its
-// frequency range (min5GHz_rssi and min24GHz_rssi for 5GHz and 2.4GHz networks respectively).
-// When disconnected the list of scan results should be returned if any network is found.
-// 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.
-//
-// The FW should calculate the score of all the candidates (including currently connected one)
-//   with following equation:
-//     RSSI score = (RSSI + 85) * 4;
-//     If RSSI score > initial_score_max , RSSI score = initial_score_max;
-//     final score = RSSI score
-//         + current_connection_bonus (if currently connected BSSID)
-//         + same_network_bonus (if network has SAME_NETWORK flag)
-//         + secure_bonus (if the network is not open)
-//         + band5GHz_bonus (if BSSID is on 5G)
-//     If there is a BSSID’s score > current BSSID’s score, then report the cached scan results
-//         at the end of the scan (excluding the ones on blacklist) to the upper layer.
-// Additionally, all BSSIDs that are in the BSSID blacklist should be ignored by Enhanced PNO

- * WiFi logger life cycle is as follow:

- * - At initialization time, framework will call wifi_get_ring_buffers_status

- * - When WiFi operation start framework will call wifi_start_logging
- *   so as to trigger log collection.
- * - Developper UI will provide an option to the user, so as it can set the verbose level
- *   of individual buffer as reported by wifi_get_ring_buffers_status.
- * - During wifi operations, driver will periodically report per ring data to framework
- *   by invoking the on_ring_buffer_data call back.
- * - when capturing a bug report, framework will indicate to driver that all the data
- *   has to be uploaded, urgently, by calling wifi_get_ring_data.
- *
- * The data uploaded by driver will be stored by framework in separate files, with one stream
- *   of file per ring.
- * Framework will store the files in pcapng format, allowing for easy merging and parsing
- *   with network analyzer tools.

-/* 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.
