+# Rust Skeleton Audio Control HAL implementation.
+
+WARNING: This is not a reference audio control HAl implementation and does
+not contain any actual implementation.
+
+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.
+
+This implementation returns `StatusCode::UNKNOWN_ERROR` for all operations
+and does not pass VTS/CTS. Vendor must replace the logic in
+`default_audio_control_hal.rs` with the actual implementation.

+     *   are some scenarios that can describe what the VehiclePropConfig.access value should be for
+     *   this property.
+     *   1. LEFT is READ and RIGHT is READ_WRITE. VehiclePropConfig.access must be READ as that is
+     *      the maximal common access across all areaIds.
+     *   2. LEFT is READ_WRITE and RIGHT is READ_WRITE. VehiclePropConfig.access must be READ_WRITE
+     *      as that is the maximal common access across all areaIds.
+     *   3. LEFT is WRITE and RIGHT is WRITE. VehiclePropConfig.access must be WRITE as that is the
+     *      maximal common access across all areaIds.
+     *   4. LEFT is READ_WRITE and RIGHT is not set (i.e. defaults to NONE)/is set to NONE, with the
+     *      expectation that RIGHT should be populated with the default access mode of the property.
+     *      VehiclePropConfig.access can be set to READ or READ_WRITE, whatever the OEM feels is the
+     *      appropriate default access for the property.
+     *   5. LEFT is READ and RIGHT is not set (i.e. defaults to NONE)/is set to NONE, with the
+     *      expectation that RIGHT should be populated with the default access mode of the property.
+     *      VehiclePropConfig.access must be set to READ because setting to READ_WRITE breaks the
+     *      rule of having the global access being the maximal subset of the area config accesses.
+     *      If the OEM wants RIGHT to be READ_WRITE in this scenario, the config should be rewritten
+     *      such that LEFT is not set/is set to NONE and RIGHT is set to READ_WRITE with
+     *      VehiclePropConfig.access set to READ.
+     *   6. LEFT is READ_WRITE and RIGHT is set to NONE with the intention of RIGHT to specifically
+     *      have no access. VehiclePropConfig.access must be NONE to support RIGHT maintaining its
+     *      NONE access.
+     *   7. LEFT is READ_WRITE and RIGHT is WRITE. This is unsupported behaviour and the config
+     *      should not be defined this way.

+WARNING: This is not a reference BroadcastRadio HAL implementation and does
+not contain any actual implementation.
+
+This folder contains a skeleton broadcast radio HAL implementation in Rust to
+demonstrate  how vendor may implement a Rust broadcast radio HAL. To run this
+broadcast radio HAL, include `android.hardware.broadcastradio-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
+`default_broadcastradio_hal.rs` with the actual implementation

+# Fuzzers for libkeymint_support
+
+## Plugin Design Considerations
+The fuzzer plugins for libkeymint_support are designed based on the understanding of the source code and try to achieve the following:
+
+#### Maximize code coverage
+The configuration parameters are not hardcoded, but instead selected based on incoming data. This ensures more code paths are reached by the fuzzers.
+
+#### Maximize utilization of input data
+The plugins feed the entire input data to the module. This ensures that the plugins tolerate any kind of input (empty, huge, malformed, etc) and dont `exit()` on any input and thereby increasing the chance of identifying vulnerabilities.

 It is important to distinquish the RKP VM from other components, such as KeyMint. An
 [RKP VM marker](https://pigweed.googlesource.com/open-dice/+/HEAD/docs/android.md#configuration-descriptor)
-(key `-70006) is used for this purpose. The existence or absence of this marker is used to
+(key `-70006`) is used for this purpose. The existence or absence of this marker is used to
 identify the type of component decribed by a given DICE chain.
 
 The following describes which certificate types may be request based on the RKP VM marker:

+// 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;

+ * data packet counters shall not increase regardless of the number of BAR potentially sent by device for this a-mpdu
+ * data packet counters shall not increase regardless of the number of BA received by device for this a-mpdu

+ * For each subsequent retransmission of the 11 remaining non ACK'ed mpdus

+ *  The implementation and the mitigation action mapping to each mode is chip

+ *  WIFI_MITIGATION_NONE mode is sent
+ *
+ *  mode: Thermal mitigation mode
+ *  WIFI_MITIGATION_NONE     : Clear all Wifi thermal mitigation actions
+ *  WIFI_MITIGATION_LIGHT    : Light Throttling where UX is not impacted
+ *  WIFI_MITIGATION_MODERATE : Moderate throttling where UX not largely impacted
+ *  WIFI_MITIGATION_SEVERE   : Severe throttling where UX is largely impacted
+ *  WIFI_MITIGATION_CRITICAL : Platform has done everything to reduce power
+ *  WIFI_MITIGATION_EMERGENCY: Key components in platform are shutting down
+ *
+ *  completion_window
+ *  Deadline (in milliseconds) to complete this request, value 0 implies apply
+ *  immediately. Deadline is basically a relaxed limit and allows vendors to
+ *  apply the mitigation within the window (if it cannot apply immediately)
+ *
+ *  Return
+ *  WIFI_ERROR_NOT_SUPPORTED : Chip does not support thermal mitigation
+ *  WIFI_ERROR_BUSY          : Mitigation is supported, but retry later
+ *  WIFI_ERROR_NONE          : Mitigation request has been accepted

+ * WiFi logger life cycle is as follow:
+ *
+ * - At initialization time, framework will call wifi_get_ring_buffers_status
+ *   so as to obtain the names and list of supported buffers.
+ * - 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.
