 /**
- * Interface representing a remote wakeup client.
+ * The remote access HAL.
  *
- * A wakeup client is a binary outside Android framework that communicates with
- * a wakeup server and receives wake up command.
+ * <p>This HAL represents an external system that is always on even when Android
+ * is powered off. It is capable of wakeing up and notifying Android when a
+ * remote task arrives.
+ *
+ * <p>For cloud-based remote access, a cloud server will issue the remote task
+ * to the external system, which will then be forwarded to Android. The client
+ * is expected to call {@code setRemoteTaskCallback} to register the remote
+ * task callback and uses the information returned from {@code getVehicleId},
+ * {@code getWakeupServiceName} and {@code getProcessorId} to register with
+ * a remote server.
+ *
+ * <p>For serverless remote access, the remote task comes from the external
+ * system alone and no server is involved. The external system may support
+ * scheduling a remote task to executed later through {@code scheduleTask}.
+ *
+ * <p>For both cloud-based and serverless remote access, the ideal use case
+ * is to wake up Android when the vehicle is not in use and then shutdown
+ * Android after the task is complete. However, user may access the vehicle
+ * during this period, and Android must not be shutdown if this happens.
+ *
+ * <p>If this interface is implemented, then VHAL property
+ * {@code VEHICLE_IN_USE} must be supported to represent whether the vehicle is
+ * currently in use. Android will check this before sending the shutdown
+ * request.
+ *
+ * <p>The external power controller system must also check whether vehicle is
+ * in use upon receiving the shutdown request and makes sure that an
+ * user-unexpected shutdown must not happen.

+// 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

+//
+// 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.

 ## Enabling Face Virtual HAL
 
-On pixel devicse (non-CF), by default (after manufacture reset), Face VHAL is not enabled. Therefore real Face HAL is used.
-Face VHAL enabling is gated by the following two AND conditions:
-1. The Face VHAL feature flag (as part of Trunk-development strategy) must be tured until the flags life-cycle ends.
-2. The Face VHAL must be enabled via sysprop
-See adb commands below

+### AcquiredInfo
 
-## Enrollment via Setup
+AcquiredInfo codes can be sent during authentication by specifying the sysprop.<br/>
+The codes is sent in sequence and in the interval of operation_authentication_duration/numberOfAcquiredInfoCode
+`shell
+$ adb shell setprop vendor.face.virtual.operation_authenticate_acquired 6,9,1013`
+Refer to [AcquiredInfo.aidl](https://source.corp.google.com/h/googleplex-android/platform/superproject/main/+/main:hardware/interfaces/biometrics/face/aidl/android/hardware/biometrics/face/AcquiredInfo.aidl) for full face acquiredInfo codes.

+
+### Error Insertion
+
+Error can be inserted during authentction by specifying the authenticate_error

+Note: Enrollment data and configuration can be supported upon request in case of needs
+
+## Lockout
+
+Device lockout is based on the number of consecutive failed authentication attempts. There are a few
+flavors of lockout mechanisms that are supported by virtula HAL <br/>
+
+### Permanent Lockout
+
+There are two sysprop to control permanent lockout <br/>
+1. general lockout feature enable <br/>
+2. threshold of failed attempts <br/>
+`shell
+$ adb shell setprop persist.vendor.face.virtual.lockout_enable true
+$ adb shell setprop persist.vendor.face.virtual.lockout_permanent_threshold 3`
+
+### Temporary Lockout
+
+There are a few parameters to control temporary lockout (aka timed lockout): <br/>
+1. enable lockout (general lockout feature enable, and timed lcokout enable) <br/>
+2. threshold of failed attempts <br/>
+3. timeout in ms <br/>
+`shell
+$ adb shell setprop persist.vendor.face.virtual.lockout_enable true
+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_enable true
+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_threshold 5
+$ adb shell setprop persist.vendor.face.virtual.lockout_timed_duration 10000`
+
+### Forced Lockout
+
+A permanent lockout can be inserted on next authentication attempt independent of the failed <br/>
+attempt count. This is a feature purely for test purpose.
+`shell
+$ adb shell setprop persist.vendor.face.virtual.lockout true`

+// 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 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.

+// 2). this is a 'current' file. If you make a backwards compatible change to

+//
+// 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.

+### Support for Android Virtualization Framework
+
+The Android Virtualization Framwork (AVF) relies on RKP to provision keys for VMs. A
+privileged vm, the RKP VM, is reponsible for generating and managing the keys for client
+VMs that run virtualized workloads. See the following for more background information on the
+RKP VM:
+*    [rkp-vm](https://android.googlesource.com/platform/packages/modules/Virtualization/+/main/service_vm/README.md#rkp-vm-remote-key-provisioning-virtual-machine)
+*    [rkp-service](https://source.android.com/docs/core/ota/modular-system/remote-key-provisioning#stack-architecture)
+
+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
+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:
+1. "rkp-vm": If a DICE chain has zero or more certificates without the RKP VM
+   marker followed by one or more certificates with the marker, then that chain
+   describes an RKP VM. If there are further certificates without the RKP VM
+   marker, then the chain does not describe an RKP VM.
+
+   Implementations must include the first RPK VM marker as early as possible
+   after the point of divergence between TEE and non-TEE components in the DICE
+   chain, prior to loading the Android Bootloader (ABL).
+2. "widevine" or "keymint": If there are no certificates with the RKP VM
+   marker then it describes a TEE component.
+3. None: Any component described by a DICE chain that does not match the above
+   two categories.

+// 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.
