* internal components of the stream while serving commands invoked via the
* stream's AIDL interface and commands invoked via the command queue of the
* descriptor.
+ *
+ * There is a state machine defined for the stream, which executes on the
+ * thread handling the commands from the queue. The states are defined based
+ * on the model of idealized producer and consumer connected via a ring buffer.
+ * For input streams, the "producer" is hardware, the "consumer" is software,
+ * for outputs streams it's the opposite. When the producer is active, but
+ * the buffer is full, the following actions are possible:
+ * - if the consumer is active, the producer blocks until there is space,
+ * this behavior is only possible for software producers;
+ * - if the consumer is passive:
+ * - the producer can preserve the buffer contents—a s/w producer can
+ * keep the data on their side, while a h/w producer can only drop captured
+ * data in this case;
+ * - or the producer overwrites old data in the buffer.
+ * Similarly, when an active consumer faces an empty buffer, it can:
+ * - block until there is data (producer must be active), only possible
+ * for software consumers;
+ * - walk away with no data; when the consumer is hardware, it must emit
+ * silence in this case.
+ *
+ * The model is defined below, note the asymmetry regarding the 'IDLE' state
+ * between input and output streams:
+ *
+ * Producer | Buffer state | Consumer | Applies | State
+ * active? | | active? | to |
+ * ==========|==============|==========|=========|==============================
+ * No | Empty | No | Both | STANDBY
+ * ----------|--------------|----------|---------|-----------------------------
+ * Yes | Filling up | No | Input | IDLE, overwrite behavior
+ * ----------|--------------|----------|---------|-----------------------------
+ * No | Empty | Yes† | Output | IDLE, h/w emits silence
+ * ----------|--------------|----------|---------|-----------------------------
+ * Yes | Not empty | Yes | Both | ACTIVE, s/w x-runs counted
+ * ----------|--------------|----------|---------|-----------------------------
+ * Yes | Filling up | No | Input | PAUSED, drop behavior
+ * ----------|--------------|----------|---------|-----------------------------
+ * Yes | Filling up | No† | Output | PAUSED, s/w stops writing once
+ * | | | | the buffer is filled up;
+ * | | | | h/w emits silence.
+ * ----------|--------------|----------|---------|-----------------------------
+ * No | Not empty | Yes | Both | DRAINING
+ * ----------|--------------|----------|---------|-----------------------------
+ * No | Not empty | No† | Output | DRAIN_PAUSED,
+ * | | | | h/w emits silence.
+ *
+ * † - note that for output, "buffer empty, h/w consuming" has the same outcome
+ * as "buffer not empty, h/w not consuming", but logically these conditions
+ * are different.
+ *
+ * State machines of both input and output streams start from the 'STANDBY'
+ * state. Transitions between states happen naturally with changes in the
+ * states of the model elements. For simplicity, we restrict the change to one
+ * element only, for example, in the 'STANDBY' state, either the producer or the
+ * consumer can become active, but not both at the same time. States 'STANDBY',
+ * 'IDLE', 'READY', and '*PAUSED' are "stable"—they require an external event,
+ * whereas a change from the 'DRAINING' state can happen with time as the buffer
+ * gets empty.
+ *
+ * The state machine for input streams is defined in the `stream-in-sm.gv` file,
+ * for output streams—in the `stream-out-sm.gv` file. State machines define how
+ * commands (from the enum 'CommandCode') trigger state changes. The full list
+ * of states and commands is defined by constants of the 'State' enum. Note that
+ * the 'CLOSED' state does not have a constant in the interface because the
+ * client can never observe a stream with a functioning command queue in this
+ * state. The 'ERROR' state is a special state which the state machine enters
+ * when an unrecoverable hardware error is detected by the HAL module.

+ <!-- Overview.
+ This example config file was copy from existing one: frameworks/av/media/libeffects/data/
+ audio_effects.xml, with effect library names updated to AIDL libraries we currently have.
+
+ All "library" attributes in "effect" element must must match a "library" element with the
+ same value of the "name" attribute.
+ All "effect" attributes in "preprocess" and "postprocess" element must match an "effect"
+ element with the same value of the "name" attribute.
+
+ AIDL EffectFactory are relying on the "name" attribute in "effect" element to identify the
+ effect type, so it's necessary to have the mapping from name to effect type UUID. Make
+ sure to either use existing effect name as key of
+ ::android::hardware::audio::effect::kUuidNameTypeMap, or add a new {name, typeUUID} map
+ item to the kUuidNameTypeMap.
+
+ Existing audio_effects.xml should working without any change as long as:
+ 1. "path" attribute of "library" element matches with the actual effect library name.
+ 2. "name" attribute of "effect" and "effectProxy" element correctly added as key of
+ kUuidNameTypeMap, with value matches Identity.type in Descriptor.aidl.
+ 3. "uuid" attribute of "effect" element matches Identity.uuid in Descriptor.aidl.
+ 4. "uuid" attribute of "effectProxy" element matches Identity.proxy in Descriptor.aidl.

+ The "uuid" attribute is the implementation specific UUID as specified by the effect vendor.

+# Test GRPC Server.
+
+A test GRPC server that implements wakeup_client.proto. This test server acts
+as a reference implementation for a remote wakeup client running on TCU. The
+test server does not communicate with any actual network server. It has the
+following behavior:
+
+* It starts a GRPC server on 'DGRPC_SERVICE_ADDRESS' compile flag which is
+ localhost:50051. The GRPC server provides the service according to
+ hardware/interfaces/automotive/remoteaccess/hal/default/proto/wakeup_client.proto.
+
+ In real implementation, DGRPC_SERVICE_ADDRESS can be specified to any IP
+ address where the TCU can be exposed to Application Processor. The default
+ remote access HAL implementation
+ (hardware/interfaces/automotive/remoteaccess/hal/default/Android.bp) also
+ uses DGRPC_SERVICE_ADDRESS to find this GRPC server, so it must have the
+ same IP address.
+
+* It generates a fake task using FakeTaskGenerator every 'kTaskIntervalInMs' ms.
+
+ In real implementation, it should receive task from the remote server.
+
+* Each fake task has an increasing unique client ID. The task data is always
+ what's defined for 'DATA' variable.
+
+ In real implementation, the client ID and task data should come from the
+ remote server.
+
+* The generated tasks are put into a task queue which is a priority queue sorted
+ by task received time.
+
+ In real implementation, if the server provides a task timestamp, then this
+ queue can be sorted by that task timestamp instead.
+
+* When the Application processor is started, the remote access HAL running on
+ Android will call 'GetRemoteTasks' to establish a long-live connection. This
+ connection is used to deliver all task data from remote wakeup client to
+ remote access HAL, which eventually to car service and applications.
+
+ When the 'GetRemoteTasks' is called, the wakeup client must send all the
+ pending tasks through the 'ServerWriter'. If no task is pending, then it must
+ block and wait for a new task to arrive.
+
+ If one task data fails to be sent through the channel, it likely means
+ the other side (Application processor) is shutting down or has closed the
+ channel. The wakeup client must put the task back to the pending queue and
+ wait for a new 'GetRemoteTasks' request to retry sending the task.
+
+* When a new task arrives, if 'WakeupRequired' is true, then try to wakeup
+ the Application Processor by sending a specific CAN message. It is possible that
+ the waking up is already in progress. This is okay since Vehicle Processor
+ should ignore wakeup message if a wakeup is already in progress.
+
+* When 'WakeupRequired' is updated from false to true, if there are unexpired
+ pending tasks in the task queue, try to wakeup Application Processor.
+
+ This is to handle the situation when a task arrives while the device is
+ shutting down. During the device shutdown, the channel to deliver the remote
+ tasks to Application Processor is shutdown so the new task will be added to the
+ task queue. 'WakeupRequired' will be set to false to prevent the wakeup
+ message preventing the shutdown. After the shutdown is complete,
+ 'WakeupRequired' will be set to true and this wakeup client must try to wake
+ up the device again to execute the pending tasks.
+
+* Every pending task has a timeout: 'kTaskTimeoutInMs'. If the pending task
+ is not delivered to remote access HAL before the timeout (through
+ GetRemoteTasks), the task timed out and a warning message is logged.
+
+ In real implementation, this kTaskTimeoutInMs has to be set long enough to
+ allow an Android bootup to happen. 20s is a reasonable value. When a task
+ timed out, the wakeup client should also report to remote task server about
+ the task timeout failure.
+
+## How to build the test wakeup client
+
+* Under android root: `source build/envsetup.sh`
+
+* `lunch sdk_car_x86_64-userdebug`
+
+* `make -j TestWakeupClientServer`
+
+## How to push the test wakeup client to a TCU which runs Android.
+
+* Make the target device writable:
+
+ `adb root`
+
+ `adb remount` (remount might take a while)
+
+ `adb reboot`
+
+ `adb root`
+
+ `adb remount`
+
+* Under android root: `cd $ANDROID_PRODUCT_OUT`
+
+* `adb push vendor/bin/TestWakeupClientServer /vendor/bin`
+
+* `adb shell`
+
+* `su`
+
+* `/vendor/bin/TestWakeupClientServer`
+
+## How to build and test the test wakeup client using one car emulator.
+
+In this test setup we will use one car emulator
+(sdk_car_x86_64-userdebug). We assume both the TCU and the remote access HAL
+runs on the same Android system, and they communicate through local loopback
+interface.
+
+* Under android root, `source build/envsetup.sh`
+
+* `lunch sdk_car_x86_64-userdebug`
+
+* `m -j`
+
+* Run the emulator, the '-read-only' flag is required to run multiple instances:
+
+ `emulator -writable-system -read-only`
+
+* The android lunch target: sdk_car_x86_64-userdebug and
+ cf_x86_64_auto-userdebug already contains the default remote access HAL. For
+ other lunch target, you can add the default remote access HAL by adding
+ 'android.hardware.automotive.remoteaccess@V1-default-service' to
+ 'PRODUCT_PACKAGES' variable in mk file, see `device/generic/car/common/car.mk`
+ as example.
+
+ To verify whether remote access HAL is running, you can use the following
+ command to check:
+
+ `dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default`
+
+* Make the target device writable:
+
+ `adb root`
+
+ `adb remount` (remount might take a while)
+
+ `adb reboot`
+
+ `adb root`
+
+ `adb remount`
+
+* `make -j TestWakeupClientServer`
+
+* `adb push $ANDROID_PRODUCT_OUT/vendor/bin/TestWakeupClientServer /vendor/bin`
+
+* `adb shell`
+
+* `emulator_car_x86_64:/ # su`
+
+* `emulator_car_x86_64:/ # /vendor/bin/TestWakeupClientServer`
+
+* Remote access HAL should start by default when the car emulator starts. Now
+ the test wake up client should also be running and generating fake tasks.
+
+ Start a new session under android root
+
+ `source build/envsetup.sh`
+
+ `lunch sdk_car_x86_64-userdebug`
+
+ `adb shell`
+
+ `emulator_car_x86_64:/ # su`
+
+* Issue the command to start a simple debug callback that will capture all the
+ received tasks at the remote access HAL side:
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --start-debug-callback`
+
+* Issue the following debug command to remote access HAL to establish the
+ communication channel between it and the test wakeup client. This command
+ also notifies that wakeup is not required:
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 1 0`
+
+* Wait for a while, issue the following command to show the received fake tasks:
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --show-task`
+
+ You should expect to see some received tasks printed out.
+
+* Simulate the Application Processor is shutting down by issuing the following
+ command:
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 0 0`
+
+* Wait for a while, issue the following command to show received tasks again:
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --show-task`
+
+ You should expect to see no new tasks received since remote access HAL already
+ closed the communication channel.
+
+* Simulate the Application Processor is already shutdown and wake up is required
+ now:
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 0 1`
+
+ Now you should expect to see the test wakeup client printing out messages
+ that it is trying to wake up application processor.
+
+* Simulate the Application Processor is waken up:
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --set-ap-state 1 0`
+
+* A new communication channel should have been established and all pending
+ non-expired tasks should be delivered to the remote access HAL.
+
+ `emulator_car_x86_64:/ # dumpsys android.hardware.automotive.remoteaccess.IRemoteAccess/default --show-task`
+
+* Now you can issue `ctrl c` on the first adb shell to stop the test wakeup
+ client.
+
+* After the test, you can use `ctrl D` to exit the adb shell.
+
+## How to build and test the test wakeup client using two car emulators.
+
+In this test case, we are going to use two car emulators, one as the
+Application Processor, one as the TCU.
+
+* Change the IP address to allow IP communication between different emulator
+ instances. For detail about why we change it this way, see [interconnecting
+ emulator instance](https://developer.android.com/studio/run/emulator-networking#connecting).
+
+ Change 'DGRPC_SERVICE_ADDRESS' in `[android_root]/hardware/interfaces/automotive/remoteaccess/test_grpc_server/impl/Android.bp` to
+ `10.0.2.15:50051`.
+
+ Change `DGRPC_SERVICE_ADDRESS` in '[android_root]/hardware/interfaces/automotive/remoteaccess/hal/defaut/Android.bp' to
+ `10.0.2.2:50051`.
+
+* Under android root: `source build/envsetup.sh`
+
+* `lunch sdk_car_x86_64-userdebug`
+
+* `m -j`
+
+* Start one car emulator as TCU
+
+ `emulator -writable-system -read-only`
+
+* Start a new shell session. Connect to the emulator's console,
+ see [Start and stop a console session](https://developer.android.com/studio/run/emulator-console#console-session)
+ for detail.
+
+ `telnet localhost 5554`
+
+* `auth auth_token` where auth_token must match the contents of the
+ `~/.emulator_console_auth_token` file.
+
+* `redir add tcp:50051:50051`
+
+* Exit the telnet session using 'ctrl-C'
+
+ Make the target device writable:
+
+ Under android root:
+
+ `source build/envsetup.sh`
+
+ `lunch sdk_car_x86_64-userdebug`
+
+ `adb root`
+
+ `adb remount` (remount might take a while)
+
+ `adb reboot`
+
+ `adb root`
+
+ `adb remount`
+
+* `make -j TestWakeupClientServer`
+
+* `adb push $ANDROID_PRODUCT_OUT/vendor/bin/TestWakeupClientServer /vendor/bin`
+
+* `adb shell`
+
+* `emulator_car_x86_64:/ # su`
+
+* `emulator_car_x86_64:/ # /vendor/bin/TestWakeupClientServer`
+
+* Start a new shell under android root, start another car emulator as the Application Processor:
+
+ `source build/envsetup.sh`
+
+ `lunch sdk_car_x86_64-userdebug`
+
+ `emulator -writable-system -read-only`
+
+* Open a new shell under android root:
+
+ `source build/envsetup.sh`
+
+ `lunch sdk_car_x86_64-userdebug`
+
+* Connect to adb shell for the application processor:
+
+ `adb -s emulator-5556 shell`
+
+ `emulator_car_x86_64:/ # su`
+
+* Follow the test instructions for one car emulator using the 'dumpsys'
+ commands.
+
+* After the test, you can use `ctrl D` to exit the adb 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.

+
+// 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 directory contains the HAL definition for KeyMint. KeyMint provides
+cryptographic services in a hardware-isolated environment.
+
+Note that the `IRemotelyProvisionedComponent` HAL, and it's associated types,
+used to also be defined in this directory. As of Android U, this HAL has been
+moved to a different directory (../rkp). This move is ABI compatible, as the
+interfaces have been maintained. The build is split so that the generated
+code may be built with different options.

+// 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.
