+// 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 is a virtual HAL implementation that is backed by system properties instead
+of actual hardware. It's intended for testing and UI development on debuggable
+builds to allow devices to masquerade as alternative device types and for
+emulators. Note: The virtual face HAL feature development will be done in
+phases. Refer to this doc often for the latest supported features
 
-## Device Selection
+## Supported Devices
 
-You can either run the FakeFaceEngine on a [real device](#actual-device) or a [virtual device/cuttlefish](#getting-started-on-a-virtual-device-cuttlefish). This document should
-help you to get started on either one.
+The face virtual hal is automatically built in in all debug builds (userdebug<br/>
+and eng) for the latest pixel devices and CF. The instructions in this doc<br/>
+applies to all
 
-After setting up a device, go ahead and try out [enrolling](#enrolling) & [authenticating](#authenticating)
+## Enabling Face Virtual HAL
 
-### Getting started on a Virtual Device (cuttlefish)
+On pixel devicse (non-CF), by default (after manufacture reset), Face VHAL is <br/>
+not enabled. Therefore real Face HAL is used. Face VHAL enabling is gated by the<br/>
+following two AND conditions:<br/>
+1. The Face VHAL feature flag (as part ofTrunk-development strategy) must be<br/>
+   turned on until the flags life-cycle ends.
+2. The Face VHAL must be enabled via sysprop.
 
+See the adb commands below
 
-Note, I'm running this via a cloudtop virtual device.
+## Getting Stared
 
-1. Setup cuttlefish on cloudtop, See [this](https://g3doc.corp.google.com/company/teams/android/teampages/acloud/getting_started.md?cl=head) for more details.
-2. acloud create --local-image
-3. Enter in the shell command to disable hidl
+A basic use case for a successful authentication via Face VHAL is given as an
+exmple below.
+
+### Enabling VHAL
 
 ```shell
 $ adb root
-$ adb shell settings put secure com.android.server.biometrics.AuthService.hidlDisabled 1
-$ adb reboot
-```
-4. You should now be able to do fake enrollments and authentications (as seen down below)
-
-### Actual Device
-
-1. Modify your real devices make file (I.E. vendor/google/products/{YOUR_DEVICE}.mk)
-2. Ensure that there is no other face HAL that is being included by the device
-3. Add the following
-```
-PRODUCT_COPY_FILES += \
-    frameworks/native/data/etc/android.hardware.biometrics.face.xml:$(TARGET_COPY_OUT_PRODUCT)/etc/permissions/android.hardware.biometrics.face.xml
-
-PRODUCT_PACKAGES += \
-    android.hardware.biometrics.face-service.example \
-
-```
-4. Now build and flash m -j120 && flash
-5. Run the following commands
-
-```shell
-# This is a temporary workaround
-$ adb root
-$ adb shell setprop persist.vendor.face.virtual.type RGB
+$ adb shell device_config put biometrics_framework com.android.server.biometrics.face_vhal_feature true
+$ adb shell settings put secure biometric_virtual_enabled 1
 $ adb shell setprop persist.vendor.face.virtual.strength strong
-$ adb shell locksettings set-pin 0000
+$ adb shell setprop persist.vendor.face.virtual.type RGB
 $ adb reboot
 ```
 
-## Enrolling
+### Direct Enrollment
 
 ```shell
-# authenticar_id,bucket_id:duration:(true|false)....
-$ adb shell setprop vendor.face.virtual.next_enrollment 1,0:500:true,5:250:true,10:150:true,15:500:true
-$ adb shell am start -n com.android.settings/.biometrics.face.FaceEnrollIntroduction
-# If you would like to get rid of the enrollment, run the follwoing command
-$ adb shell setprop persist.vendor.face.virtual.enrollments \"\"
+$ adb shell locksettings set-pin 0000
+$ adb shell setprop persist.vendor.face.virtual.enrollments 1
+$ adb shell cmd face syncadb shell cmd face sync
 ```
 
 ## Authenticating
 
-```shell
-# If enrollment hasn't been setup
-$ adb shell setprop persist.vendor.face.virtual.enrollments 1
-$ adb shell cmd face sync
-# After enrollment has been setup
+To authenticate successfully, the captured (hit) must match the enrollment id<br/>
+set above. To trigger authentication failure, set the hit id to a different value.
+`shell
 $ adb shell setprop vendor.face.virtual.operation_authenticate_duration 800
-$ adb shell setprop vendor.face.virtual.enrollment_hit 1
-# Power button press to simulate auth
-$ adb shell input keyevent 26
+$ adb shell setprop vendor.face.virtual.enrollment_hit 1`
+
+### AcquiredInfo
+
+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.
+Note: For vendor specific acquired info, acquiredInfo = 1000 + vendorCode.
+
+### Error Insertion
+
+Error can be inserted during authentction by specifying the authenticate_error
+sysprop. `shell $ adb shell setprop
+vendor.face.virtual.operation_authenticate_error 4` Refer to
+[Error.aidl](https://source.corp.google.com/h/googleplex-android/platform/superproject/main/+/main:hardware/interfaces/biometrics/face/aidl/android/hardware/biometrics/face/Error.aidl)
+for full face error codes
+
+## Enrollment via Settings
+
+Enrollment process is specified by sysprop `next_enrollment` in the following
+format
+
+```shell
+Format: <id>:<progress_ms-[acquiredInfo,...],...:<success>
+        ----:-----------------------------------:---------
+        |           |                               |--->sucess (true/false)
+        |           |--> progress_step(s)
+        |
+        |-->enrollment_id
+
+E.g.
+$ adb shell setprop vendor.face.virtual.next_enrollment 1:6000-[21,8,1,1108,1,10,1113,1,1118,1124]:true
 ```
+
+If next_enrollment prop is not set, the following default value is used:<br/>
+&nbsp;&nbsp;defaultNextEnrollment="1:1000-[21,7,1,1103],1500-[1108,1],2000-[1113,1],2500-[1118,1]:true"<br/>
+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.

-     * It is safest to assume the buffer is an image with sRGB primaries and
-     * encoding ranges, but the consumer and/or the producer of the data may
-     * simply be using defaults. No automatic gamma transform should be
-     * expected, except for a possible display gamma transform when drawn to a
-     * screen.
+     * IAllocator implementations must not assume a particular dataspace interpretation when
+     * allocating a buffer. That is, the dataspace stored on a buffer's metadata must
+     * explicitly be UNKNOWN at the time of allocation. All other vendor implementations (for
+     * example, IComposer) are suggested to assume that the buffer is an image that conforms
+     * to the recommendations outlined by STANDARD_UNSPECIFIED, TRANSFER_UNSPECIFIED, and
+     * RANGE_UNSPECIFIED in order to avoid obviously-broken behavior.
+     *
+     * This means:
+     * - RGB buffers may be assumed to follow sRGB (IEC 61966-2.1)
+     * - YCbCr buffers smaller than 720p may be assumed to follow BT. 601-7
+     * - YCbCr buffers at least 720p may be assumed to follow BT. 709-6
+     * - Y buffers are full range with an undefined transfer and primaries
+     * - All other buffer formats may be treated in an implementation-defined manner
+     *
+     * It is the framework's - and application's - responsibility to communicate
+     * an accurate dataspace for any buffers throughout the system to guarantee
+     * well-defined behavior. For the framework, this means translating UNKNOWN
+     * dataspaces to a chosen default, and setting gralloc metadata on the buffer
+     * accordingly. For the application, this means signaling a defined dataspace
+     * to any framework apis.

+
+// 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.

-     * the UNLOCKED_DEVICE_REQUIRED tag should no longer be usable.  When this function is called,
-     * the IKeyMintDevice should note the current timestamp, and attempts to use
-     * UNLOCKED_DEVICE_REQUIRED keys must be rejected with Error::DEVICE_LOCKED until an
-     * authentication token with a later timestamp is presented.  If the `passwordOnly' argument is
-     * set to true the sufficiently-recent authentication token must indicate that the user
-     * authenticated with a password, not a biometric.
+     * This method is deprecated and has never been used.  Implementations should return
+     * ErrorCode::UNIMPLEMENTED.
      *
-     * Note that the IKeyMintDevice UNLOCKED_DEVICE_REQUIRED semantics are slightly different from
-     * the UNLOCKED_DEVICE_REQUIRED semantics enforced by keystore.  Keystore handles device locking
-     * on a per-user basis.  Because auth tokens do not contain an Android user ID, it's not
-     * possible to replicate the keystore enforcement logic in IKeyMintDevice.  So from the
-     * IKeyMintDevice perspective, any user unlock unlocks all UNLOCKED_DEVICE_REQUIRED keys.
-     * Keystore will continue enforcing the per-user device locking.
+     * This method was originally intended to be used to notify KeyMint that the device is now
+     * locked, and keys with the UNLOCKED_DEVICE_REQUIRED tag should no longer be usable until a
+     * later valid HardwareAuthToken is presented.  However, Android has never called this method
+     * and it cannot start doing so, because KeyMint's enforcement of UNLOCKED_DEVICE_REQUIRED did
+     * not provide the correct semantics and therefore could never be enabled.  Specifically, the
+     * following issues existed with the design of KeyMint's enforcement of
+     * UNLOCKED_DEVICE_REQUIRED:
      *
-     * @param passwordOnly specifies whether the device must be unlocked with a password, rather
-     * than a biometric, before UNLOCKED_DEVICE_REQUIRED keys can be used.
+     * o It assumed a global device lock state only.  Android actually has a separate lock state for
+     *   each user.  See the javadoc for KeyguardManager#isDeviceLocked().
+     * o It assumed that unlocking the device involves a successful user authentication that
+     *   generates a HardwareAuthToken.  This is not necessarily the case, since Android supports
+     *   weaker unlock methods including class 1 and 2 biometrics and trust agents.  These unlock
+     *   methods do not generate a HardwareAuthToken or interact with KeyMint in any way.  Also,
+     *   UNLOCKED_DEVICE_REQUIRED must work even for users who do not have a secure lock screen.
+     * o It would have made UNLOCKED_DEVICE_REQUIRED incompatible with requiring user
+     *   authentication in some cases.  These two key protections can each require a different
+     *   HardwareAuthToken, but KeyMint only supports one HardwareAuthToken per operation.
+     * o It would have provided no security benefit over Keystore's enforcement of
+     *   UNLOCKED_DEVICE_REQUIRED.  This is because since Android 12, Keystore enforces
+     *   UNLOCKED_DEVICE_REQUIRED not just logically, but it also cryptographically by
+     *   superencrypting all such keys and wiping or re-encrypting the superencryption key when the
+     *   device is locked (whenever possible).  KeyMint is still used to support biometric unlocks,
+     *   but this mechanism does not use KeyMint's direct enforcement of UNLOCKED_DEVICE_REQUIRED.
      *
-     * @param timestampToken is used by StrongBox implementations of IKeyMintDevice.  It
-     * provides the StrongBox IKeyMintDevice with a fresh, MACed timestamp which it can use as the
-     * device-lock time, for future comparison against auth tokens when operations using
-     * UNLOCKED_DEVICE_REQUIRED keys are attempted.  Unless the auth token timestamp is newer than
-     * the timestamp in the timestampToken, the device is still considered to be locked.
-     * Crucially, if a StrongBox IKeyMintDevice receives a deviceLocked() call with a timestampToken
-     * timestamp that is less than the timestamp in the last deviceLocked() call, it must ignore the
-     * new timestamp.  TEE IKeyMintDevice implementations will receive an empty timestampToken (zero
-     * values and empty vectors) and should use their own clock as the device-lock time.
+     * Therefore, this method is not useful, and there is no reason for it be called.
+     * Implementations should return ErrorCode::UNIMPLEMENTED and should not include
+     * UNLOCKED_DEVICE_REQUIRED in the list of hardware-enforced key parameters.
+     *
+     * @param passwordOnly N/A due to the deprecation
+     * @param timestampToken N/A due to the deprecation

+// 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.

+// 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)

+ * 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
+ * (regardless of the fact that they are transmitted in a-mpdu or not)

+/**
+ * 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.
