+# Fuzzer for android.hardware.automotive.vehicle@2.0-manager-lib
+
+## Plugin Design Considerations
+The fuzzer plugin for android.hardware.automotive.vehicle@2.0-manager-lib is
+designed based on the understanding of the library and tries 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 fuzzer.
+
+Vehicle Manager supports the following parameters:
+1. Vehicle Property (parameter name: `vehicleProp`)
+2. Diagnostic Integer Sensor Index (parameter name: `diagnosticIntIndex`)
+3. Diagnostic Float Sensor Index (parameter name: `diagnosticFloatIndex`)
+4. Availability Message Type (parameter name: `availabilityMsgType`)
+5. Subscription Message Type (parameter name: `subscriptionMsgType`)
+
+| Parameter| Valid Values| Configured Value|
+|------------- |-------------| ----- |
+| `vehicleProp` | 0.`VehicleProperty::INVALID` 1.`VehicleProperty::HVAC_FAN_SPEED` 2.`VehicleProperty::INFO_MAKE` 3.`VehicleProperty::DISPLAY_BRIGHTNESS`  4.`VehicleProperty::INFO_FUEL_CAPACITY` 5.`VehicleProperty::HVAC_SEAT_TEMPERATURE`| Value obtained from FuzzedDataProvider |
+| `diagnosticIntIndex`   | 0.`DiagnosticIntegerSensorIndex::FUEL_SYSTEM_STATUS` 1.`DiagnosticIntegerSensorIndex::MALFUNCTION_INDICATOR_LIGHT_ON` 2.`DiagnosticIntegerSensorIndex::NUM_OXYGEN_SENSORS_PRESENT` 3.`DiagnosticIntegerSensorIndex::FUEL_TYPE`  | Value obtained from FuzzedDataProvider |
+| `diagnosticFloatIndex`   | 0.`DiagnosticFloatSensorIndex::CALCULATED_ENGINE_LOAD` 1.`DiagnosticFloatSensorIndex::SHORT_TERM_FUEL_TRIM_BANK1` 2.`DiagnosticFloatSensorIndex::LONG_TERM_FUEL_TRIM_BANK1` 3.`DiagnosticFloatSensorIndex::THROTTLE_POSITION`  | Value obtained from FuzzedDataProvider |
+| `availabilityMsgType`   | 0.`VmsMessageType::AVAILABILITY_CHANGE` 1.`VmsMessageType::AVAILABILITY_RESPONSE` | Value obtained from FuzzedDataProvider |
+| `subscriptionMsgType`   | 0.`VmsMessageType::SUBSCRIPTIONS_CHANGE` 1.`VmsMessageType::SUBSCRIPTIONS_RESPONSE` | Value obtained from FuzzedDataProvider |
+
+This also ensures that the plugin is always deterministic for any given input.
+
+## Build
+
+This describes steps to build vehicleManager_fuzzer binary.
+
+### Android
+
+#### Steps to build
+Build the fuzzer
+```
+  $ mm -j$(nproc) vehicleManager_fuzzer
+```
+
+#### Steps to run
+Create a directory CORPUS_DIR
+```
+  $ adb shell mkdir /data/local/tmp/CORPUS_DIR
+```
+
+##### Some Additional steps needed to run the vehicleManager_fuzzer successfully on device
+
+1. Push the following libraries from /vendor/lib/ and /vendor/lib64/ folders of your workspace to the device's /vendor/lib/ and /vendor/lib64/ :
+```
+1.1  android.hardware.automotive.vehicle@2.0.so
+1.2  carwatchdog_aidl_interface-V2-ndk_platform.so
+```
+2. Now, reboot the device using command
+```
+  $ adb reboot
+```
+
+##### To run the fuzzer on device
+```
+  $ adb sync data
+  $ adb shell LD_LIBRARY_PATH=/vendor/lib64 /data/fuzz/${TARGET_ARCH}/vehicleManager_fuzzer/vendor/vehicleManager_fuzzer /data/local/tmp/CORPUS_DIR
+```

+ * IBurst represents a burst execution object.
+ *
+ * Burst executions are a sequence of executions of the same prepared model that occur in rapid
+ * succession, such as frames of a camera capture or successive audio samples. A burst object is
+ * used to control a set of burst executions, and to preserve resources between executions, enabling
+ * executions to have lower overhead. Burst objects enable some optimizations:
+ * (1) A burst object is created before a sequence of executions, and freed when the sequence has
+ *     ended. Because of this, the lifetime of the burst object hints to a driver how long it should
+ *     remain in a high performance state.
+ * (2) A burst object can preserve resources between executions. For example, a driver can map a
+ *     memory object on the first execution and cache the mapping in the burst object for reuse in
+ *     subsequent executions. Any cached resource can be released when the burst object is destroyed
+ *     or when the NNAPI runtime notifies the burst object that the resource is no longer required.
+ * (3) A burst object may be used for at most one execution at a time. This enables any transient
+ *     execution resources such as intermediate tensors to be allocated once when the burst object
+ *     is created and freed when the burst object is destroyed.

+# KeyMint Benchmark
+
+The KeyMint Benchmark is a standalone tool for measuring the performance of
+ KeyMint implementations.
+
+## Building
+
+Build:
+`m  VtsAidlKeyMintBenchmarkTest`
+
+Transfer to device/emulator:
+`adb sync data`
+
+The benchmark executable will be located at
+ `data/benchmarktest/VtsAidlKeyMintBenchmarkTest` on the device.
+
+## Usage
+
+KeyMint Benchmark is built on [Google microbenchmark
+library](https://github.com/google/benchmark). All of the commandline arguments
+provided by the microbenchmark library are valid, such as
+`--benchmark_filter=<regex>` or `benchmark_out_format={json|console|csv}`.
+In addition to the command line arguments provided by microbenchmark,
+`--service_name=<service_name>` is provided to allow specification of the KeyMint
+fully qualified service name, e.g. specify
+`--service_name=android.hardware.security.keymint.IKeyMintDevice/default` to
+benchmark default implementation of KeyMint.

+# CEC VTS testing for Android TV devices
+
+Validate HDMI CEC VTS (android.hardware.tv.cec@1.0) functionality.
+
+### Setup:
+
+Running these CEC VTS tests requires an Android playback, TV or audio device connected to the host machine.
+
+![drawing](setup.png)
+
+### Building
+
+From the Android root folder, after choosing the lunch combo, use `make vts` to build VTS.
+
+### Automation
+
+On the host machine, ensure that the [software requirements](https://codelabs.developers.google.com/codelabs/android-lab/#2) for python SDK are met.
+
+Given the setup described above you can run tests with any of the following commands:
+
+1. Using vts-tradefed :
+```
+cd $ANDROID_BUILD_TOP/out/host/linux-x86/vts/android-vts/tools
+./vts-tradefed run commandAndExit vts -m VtsHalTvCecV1_0TargetTest
+```
+2. Using atest
+```
+atest VtsHalTvCecV1_0TargetTest
+```
+Note : atest internally handles building as well. To update the test use '-c' (clear cache) option

+                - The users can configure 1 or more frontend elements in the frontends sections.
+
+            Each frontend element contain the following attributes:
+                "id": unique id of the frontend that could be used to connect to the test the
+                    "dataFlowConfiguration"
+                "type": the frontend type. The enums are defined in the xsd.
+                "isSoftwareFrontend": if the test environment is using hardware or software
+                    frontend. If using software, a ts input file path needs to be configured.
+                "softwareFeInputPath": used as the source of the software frontend.
+                "connectToCicamId": if the device supports frontend connecting to cicam, the target
+                    cicam id needs to be configured here. Supported in Tuner 1.1 or higher.

+                "endFrequency": the end frequency of scan. Supported in Tuner 1.1 or higher.
+
+            Each frontend element also contains one and only one type-related "frontendSettings".
+                - The settings type should match the frontend "type" attribute.
+                - For example, when frontend type="DVBT", dvbtFrontendSettings can be configured.
+                - This is optional and skipping the settings would pass a setting with frequency
