-# Virtual Face HAL
+# Face Virtual HAL (VHAL)
 
 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 and eng) for the latest pixel devices and CF.
+The instructions in this doc 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 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
 
+##Getting Stared
 
-Note, I'm running this via a cloudtop virtual device.
+A basic use case for a successful authentication via Face VHAL is given as an exmple below.
 
-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
-
+### 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
+$ 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
+To authenticate successfully, the captured (hit) must match the enrollment id 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
+```
+Refer to face.sysprop for full supported features of authentication, such as error and acquiredInfo insertion
+
+
+## Enrollment via Setup
 
 ```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
+$ walk thru the manual enrollment process by following screen instructions
+
 # If you would like to get rid of the enrollment, run the follwoing command
 $ adb shell setprop persist.vendor.face.virtual.enrollments \"\"
 ```
-
-## 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
-$ 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
-```

+     * If the GPU & HWC supports EGL_SINGLE_BUFFER, then it is recommended that

-     * 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.
