+                   and output devices or between stream and devices.

+                 - <attachedDevices/>: permanently attached devices.
+                   The attachedDevices section is a list of devices names.
+                   Their names correspond to device names defined in "devicePorts" section.

+ *     input.  It is not permitted for no bits to be set.
+ *
+ * All other representations are reserved for future use.
+ *
+ * Warning: current representation distinguishes between input and output, but
+ * this will not the be case in future revisions of the platform. Wherever there

+-----------------------------------------------------------
+WHAT WAS *NOT* DONE, and you need to do now:
+ 1) You need to choose if the new HAL is optional or not for new devices.
+    Either add or replace $BASE_VERSION by $NEW_VERSION in
+    compatibility_matrices/compatibility_matrix.current.xml
+    Do not forget to update both the "audio" and "audio.effects" HAL'
+
+ 2) Then you need to choose a device to update its audio HAL implementation:
+    a) Update the HAL manifest of your device: open your device manifest.xml
+       and replace $BASE_VERSION by $NEW_VERSION for both
+        - android.hardware.audio
+        - android.hardware.audio.effect
+    b) Go to your device device.mk (usually next to the manifest) and replace:
+        - android.hardware.audio@$BASE_VERSION-impl by
+          android.hardware.audio@$NEW_VERSION-impl
+        - android.hardware.audio.effect@$BASE_VERSION-impl by
+          android.hardware.audio.effect@$NEW_VERSION-impl

+   See http://www.w3.org/XML/1998/namespace.html and

+
+    This schema document describes the XML namespace, in a form
+    suitable for import by other schema documents.
+
+    Note that local names in this namespace are intended to be defined
+    only by the World Wide Web Consortium or its subgroups.  The
+    following names are currently defined in this namespace and should
+    not be used with conflicting semantics by any Working Group,
+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    id   (as an attribute name): denotes an attribute whose value
+         should be interpreted as if declared to be of type ID.
+         The xml:id specification is not yet a W3C Recommendation,
+         but this attribute is included here to facilitate experimentation
+         with the mechanisms it proposes.  Note that it is _not_ included
+         in the specialAttrs attribute group.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of
+         the original XML Working Group.  This name is reserved by
+         the following decision of the W3C XML Plenary and
+         XML Coordination groups:
+
+             In appreciation for his vision, leadership and dedication
+             the W3C XML Plenary on this 10th day of February, 2000
+             reserves for Jon Bosak in perpetuity the XML name
+             xml:Father

+  <xs:documentation>This schema defines attributes and an attribute group
+        suitable for use by
+        schemas wishing to allow xml:base, xml:lang, xml:space or xml:id
+        attributes on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                    schemaLocation="http://www.w3.org/2005/08/xml.xsd"/>
+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+
+         will define a type which will schema-validate an instance
+         element with any of those attributes</xs:documentation>

+
+ <xs:annotation>
+  <xs:documentation>In keeping with the XML Schema WG's standard versioning
+   policy, this schema document will persist at
+   http://www.w3.org/2005/08/xml.xsd.
+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema
+   itself, or with the XML namespace itself.  In other words, if the XML
+   Schema or XML namespaces change, the version of this document at
+   http://www.w3.org/2001/xml.xsd will change
+   accordingly; the version at
+   http://www.w3.org/2005/08/xml.xsd will not change.

+# parameter-framework configuration file XML Schemas
+
+These are W3C Schemas for the various configuration files.
+
+`xmllint` may be used to check for correctness, e.g:
+
+    xmllint --xinclude --noout --schema ParameterFrameworkConfiguration.xsd /path/to/your/ParameterFrameworkConfiguration.xml
+
+See `tools/xmlValidator` for a custom alternative tool.
+
+Only `ParameterFrameworkConfiguration.xsd`, `SystemClass.xsd`, `Subsystem.xsd` and
+`ConfigurableDomains.xsd` are relevant for use with xmllint: the others are
+included by these 4 XSDs.
+
+**You may refer to samples at
+<https://github.com/01org/parameter-framework-samples>.**
+
+## ParameterFrameworkConfiguration.xsd
+
+Schema for the **top-level configuration**.  It contains:
+
+- A reference to the `SystemClass` (aka StructureDescription) XML file (see
+  below);
+- The list of plugins (libraries) to be used. They may be split according to
+the folder they reside in. The `Folder` attribute can either be:
+
+    - an absolute path,
+    - a relative path (relative to the execution directory),
+    - empty.
+
+    In the first two cases, the runtime loader will be asked to explicitely load
+    the libraries found in the specified folder; in the last case (empty string)
+    the runtime loader will search for the library on its own (e.g. on Linux
+    distribution this is usually `/lib`, `/usr/lib` - see `man ld.so`)
+- Optionally, a reference to the `Settings`.
+
+Attributes of `ParameterFrameworkConfiguration` are:
+
+- The `SystemClass` name (for consistency check)
+- `TuningAllowed` (whether the parameter-framework listens for commands)
+- The `ServerPort` bind Address (PATH or TCP port) on which the parameter-framework listens if
+  `TuningAllowed=true`.
+
+## SystemClass.xsd
+
+Schema for the **SystemClass associated with the top-level configuration**.  It
+points to all the "Subsystem" files (see below).
+
+The `Name` attribute of the SystemClass must match the `SystemClass` attribute
+of the top-level configuration file. This name will be the first component of
+all parameters in it, i.e. if its name is "FooBar", its path is `/FooBar`. We
+will use this name in examples below.
+
+## Subsystem.xsd
+
+Schema for all **Subsystem files** (aka Structure files).  These files describe the
+content and structure of the system to be managed by the parameter-framework
+and also indicate which plugin is to be used.
+
+A Subsystem has the following attribute:
+
+- `Name` (self-explanatory); again it is the base component of all parameters
+  inside it; i.e. if its name is "Spam", its path is `/FooBar/Spam`;
+- `Type`, which indicates which SubsystemBuilder is to be used (each plugin can
+  declare one or more SubsystemBuilders); it may be defined as `Virtual`, in
+  which case, no plugin will be used and the parameters won't be synchronized.
+  This is useful for debugging but may also be used for the parameter-framework
+  to act as a configurable settings database;
+- `Mapping` (optional), defines a Mapping to be inherited by all Components in
+  the Subsystem.
+
+A Subsystem *must* contain:
+
+- A `ComponentLibrary`, which may include (using `<xi:include href="xyz.xml"/>`)
+  other files containing a `<ComponentLibrary>` or a `<ComponentTypeSet>` tag.
+- An `InstanceDefinition` which instantiates the parameters and may use
+  ComponentTypes defined in the ComponentLibrary.
+
+## ConfigurableDomains.xsd
+
+Schema for the ConfigurableDomains (aka Settings files).  These files contain
+the rules for applying values to parameters.
+
+Writing this file by hand is painful but it is not intended to be dealt
+with directly: instead, you may use the command-line interface (see
+`remote-process/README.md`) to set the settings and export the resulting
+Settings with the `getDomainsWithSettingsXML` command.

+    specification, or document instance:
+
+    base (as an attribute name): denotes an attribute whose value
+         provides a URI to be used as the base for interpreting any
+         relative URIs in the scope of the element on which it
+         appears; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML Base specification.
+
+    id   (as an attribute name): denotes an attribute whose value
+         should be interpreted as if declared to be of type ID.
+         The xml:id specification is not yet a W3C Recommendation,
+         but this attribute is included here to facilitate experimentation
+         with the mechanisms it proposes.  Note that it is _not_ included
+         in the specialAttrs attribute group.
+
+    lang (as an attribute name): denotes an attribute whose value
+         is a language code for the natural language of the content of
+         any element; its value is inherited.  This name is reserved
+         by virtue of its definition in the XML specification.
+
+    space (as an attribute name): denotes an attribute whose
+         value is a keyword indicating what whitespace processing
+         discipline is intended for the content of the element; its
+         value is inherited.  This name is reserved by virtue of its
+         definition in the XML specification.
+
+    Father (in any context at all): denotes Jon Bosak, the chair of
+         the original XML Working Group.  This name is reserved by
+         the following decision of the W3C XML Plenary and
+         XML Coordination groups:
+
+             In appreciation for his vision, leadership and dedication
+             the W3C XML Plenary on this 10th day of February, 2000
+             reserves for Jon Bosak in perpetuity the XML name
+             xml:Father

+  <xs:documentation>This schema defines attributes and an attribute group
+        suitable for use by
+        schemas wishing to allow xml:base, xml:lang, xml:space or xml:id
+        attributes on elements they define.
+
+        To enable this, such a schema must import this schema
+        for the XML namespace, e.g. as follows:
+        &lt;schema . . .>
+         . . .
+         &lt;import namespace="http://www.w3.org/XML/1998/namespace"
+                    schemaLocation="http://www.w3.org/2005/08/xml.xsd"/>
+
+        Subsequently, qualified reference to any of the attributes
+        or the group defined below will have the desired effect, e.g.
+
+        &lt;type . . .>
+         . . .
+         &lt;attributeGroup ref="xml:specialAttrs"/>
+
+         will define a type which will schema-validate an instance
+         element with any of those attributes</xs:documentation>
+ </xs:annotation>
+
+ <xs:annotation>
+  <xs:documentation>In keeping with the XML Schema WG's standard versioning
+   policy, this schema document will persist at
+   http://www.w3.org/2005/08/xml.xsd.
+   At the date of issue it can also be found at
+   http://www.w3.org/2001/xml.xsd.
+   The schema document at that URI may however change in the future,
+   in order to remain compatible with the latest version of XML Schema
+   itself, or with the XML namespace itself.  In other words, if the XML
+   Schema or XML namespaces change, the version of this document at
+   http://www.w3.org/2001/xml.xsd will change
+   accordingly; the version at
+   http://www.w3.org/2005/08/xml.xsd will not change.

+     *
+     * So, the behavior of set(INITIAL_USER_INFO) is:
+     *
+     * - if it has an areaId, store the property into mInitialUserResponseFromCmd (as it was called
+     * by lshal).
+     * - else if mInitialUserResponseFromCmd is not set, return a response with the same request id
+     * and InitialUserInfoResponseAction::DEFAULT
+     * - else the behavior is defined by the areaId on mInitialUserResponseFromCmd:
+     * - if it's 1, reply with mInitialUserResponseFromCmd and the right request id
+     * - if it's 2, reply with mInitialUserResponseFromCmd but a wrong request id (so Android can
+     * test this error scenario)
+     * - if it's 3, then don't send a property change (so Android can emulate a timeout)

+     *
+     * 1.LEGACY_ANDROID_SWITCH
+     * -----------------------
+     *
+     * Called by the Android System to indicate the Android user is about to change, when the change
+     * request was made in a way that is not integrated with the HAL (for example, through
+     * adb shell am switch-user).
+     *
+     * The HAL can switch its internal user once it receives this request, but it doesn't need to
+     * reply back to the Android System. If its internal user cannot be changed for some reason,
+     * then it must wait for the SWITCH_USER(type=ANDROID_POST_SWITCH) call to recover
+     * (for example, it could issue a SWITCH_USER(type=VEHICLE_REQUEST) to switch back to
+     * the previous user), but ideally it should never fail (as switching back could result in a
+     * confusing experience for the end user).
+     *
+     * For example, if the system have users (0, 10, 11) and it's switching from 0 to 11 (where none
+     * of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  1   // SwitchUserMessageType::LEGACY_ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // user #0 (Android user id 0)
+     * int32[8]:  0   // flags of user #0 (none)
+     * int32[9]:  10  // user #1 (Android user id 10)
+     * int32[10]: 0   // flags of user #1 (none)
+     * int32[11]: 11  // user #2 (Android user id 11)
+     * int32[12]: 0   // flags of user #2 (none)
+     *
+     * 2.ANDROID_SWITCH
+     * ----------------
+     * Called by the Android System to indicate the Android user is about to change, but Android
+     * will wait for the HAL's response (up to some time) before proceeding.
+     *
+     * The HAL must switch its internal user once it receives this request, then respond back to
+     * Android with a SWITCH_USER(type=VEHICLE_RESPONSE) indicating whether its internal
+     * user was switched or not (through the SwitchUserStatus enum).
+     *
+     * For example, if Android has users (0, 10, 11) and it's switching from 10 to 11 (where
+     * none of them have any special flag), the request would be:
+     *
+     * int32[0]:  42  // request id
+     * int32[1]:  2   // SwitchUserMessageType::ANDROID_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user flags (none)
+     * int32[4]:  10  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  1   // 1st user flags (SYSTEM)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 0   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 0   // 3rd user flags (none)
+     *
+     * If the request succeeded, the HAL must update the propery with:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 3   // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 1   // status = SwitchUserStatus::SUCCESS
+     *
+     * But if it failed, the response would be something like:
+     *
+     * int32[0]: 42   // request id
+     * int32[1]: 3    // messageType = SwitchUserMessageType::VEHICLE_RESPONSE
+     * int32[2]: 2    // status = SwitchUserStatus::FAILURE
+     * string: "108-D'OH!" // OEM-spefic error message
+     *
+     * 3.VEHICLE_RESPONSE
+     * ------------------
+     * Called by the HAL to indicate whether a request of type ANDROID_SWITCH should proceed or
+     * abort - see the ANDROID_SWITCH section above for more info.
+     *
+     * 4.VEHICLE_REQUEST
+     * ------------------
+     * Called by the HAL to request that the current foreground Android user is switched.
+     *
+     * This is useful in situations where Android started as one user, but the vehicle identified
+     * the driver as another user. For example, user A unlocked the car using the key fob of user B;
+     * the INITIAL_USER_INFO request returned user B, but then a face recognition subsubsystem
+     * identified the user as A.
+     *
+     * The HAL makes this request by a property change event (passing a negative request id), and
+     * the Android system will response by issue an ANDROID_POST_SWITCH call which the same
+     * request id.
+     *
+     * For example, if the current foreground Android user is 10 and the HAL asked it to switch to
+     * 11, the request would be:
+     *
+     * int32[0]: -108  // request id
+     * int32[1]: 4     // messageType = SwitchUserMessageType::VEHICLE_REQUEST
+     * int32[2]: 11    // Android user id
+     *
+     * If the request succeeded and Android has 3 users (0, 10, 11), the response would be:
+     *
+     * int32[0]: -108 // request id
+     * int32[1]:  5   // messageType = SwitchUserMessageType::ANDROID_POST_SWITCH
+     * int32[2]:  11  // target user id
+     * int32[3]:  0   // target user id flags (none)
+     * int32[4]:  11  // current user
+     * int32[5]:  0   // current user flags (none)
+     * int32[6]:  3   // number of users
+     * int32[7]:  0   // 1st user (user 0)
+     * int32[8]:  0   // 1st user flags (none)
+     * int32[9]:  10  // 2nd user (user 10)
+     * int32[10]: 4   // 2nd user flags (none)
+     * int32[11]: 11  // 3rd user (user 11)
+     * int32[12]: 3   // 3rd user flags (none)
+     *
+     * Notice that both the current and target user ids are the same - if the request failed, then
+     * they would be different (i.e, target user would be 11, but current user would still be 10).
+     *
+     * 5.ANDROID_POST_SWITCH
+     * ---------------------
+     * Called by the Android System after a request to switch a user was made.
+     *
+     * This property is called after switch requests of any type (i.e., LEGACY_ANDROID_SWITCH,
+     * ANDROID_SWITCH, or VEHICLE_REQUEST) and can be used to determine if the request succeeded or
+     * failed:
+     *
+     * 1. When it succeeded, it's called when the Android user is in the unlocked state and the
+     *    value of the current and target users ids in the response are the same. This would be
+     *    equivalent to receiving an Intent.ACTION_USER_UNLOCKED in an Android app.
+     * 2. When it failed it's called right away and the value of the current and target users ids
+     *    in the response are different (as the current user didn't change to the target).
+     * 3. If a new switch request is made before the HAL responded to the previous one or before
+     *    the user was unlocked, then the ANDROID_POST_SWITCH request is not made. For example,
+     *    the driver could accidentally switch to the wrong user which has lock credentials, then
+     *    switch to the right one before entering the credentials.
+     *
+     * The HAL can update its internal state once it receives this request, but it doesn't need to
+     * reply back to the Android System.
+     *
+     * Request: the first N values as defined by INITIAL_USER_INFO (where the request-specific
+     * value at index 1 is SwitchUserMessageType::ANDROID_POST_SWITCH), then 2 more values for the
+     * target user id (i.e., the Android user id that was requested to be switched to) and its flags
+     * (as defined by  UserFlags).
+     *
+     * Response: none.
+     *
+     * Example: see VEHICLE_REQUEST section above.

+     * user-related functions described on INITIAL_USER_INFO.
+     *
+     * To query the association, the Android system gets the property, passing a VehiclePropValue
+     * containing the types of associations are being queried, as defined by
+     * UserIdentificationGetRequest. The HAL must return right away, returning a VehiclePropValue
+     * with a UserIdentificationResponse. Notice that user identification should have already
+     * happened while system is booting up and the VHAL implementation should only return the
+     * already identified association (like the key FOB used to unlock the car), instead of starting
+     * a new association from the get call.
+     *
+     * To associate types, the Android system sets the property, passing a VehiclePropValue
+     * containing the types and values of associations being set, as defined by the
+     * UserIdentificationSetRequest. The HAL will then use a property change event (whose
+     * VehiclePropValue is defined by UserIdentificationResponse) indicating the current status of
+     * the types after the request.
+     *
+     * For example, to query if the current user (10) is associated with the FOB that unlocked the
+     * car and a custom mechanism provided by the OEM, the request would be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 0   (Android user flags)
+     * int32[3]: 2   (number of types queried)
+     * int32[4]: 1   (1st type queried, UserIdentificationAssociationType::KEY_FOB)
+     * int32[5]: 101 (2nd type queried, UserIdentificationAssociationType::CUSTOM_1)
+     *
+     * If the user is associated with the FOB but not with the custom mechanism, the response would
+     * be:
+     *
+     * int32[0]: 42  // request id
+     * int32[1]: 2   (number of associations in the response)
+     * int32[2]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB)
+     * int32[3]: 2   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)
+     * int32[4]: 101 (2st type: UserIdentificationAssociationType::CUSTOM_1)
+     * int32[5]: 4   (2nd value: UserIdentificationAssociationValue::NOT_ASSOCIATED_ANY_USER)
+     *
+     * Then to associate the user with the custom mechanism, a set request would be made:
+     *
+     * int32[0]: 43  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 0   (Android user flags)
+     * int32[3]: 1   (number of associations being set)
+     * int32[4]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1)
+     * int32[5]: 1   (1st value: UserIdentificationAssociationSetValue::ASSOCIATE_CURRENT_USER)
+     *
+     * If the request succeeded, the response would be simply:
+     *
+     * int32[0]: 43  // request id
+     * int32[1]: 1   (number of associations in the response)
+     * int32[2]: 101 (1st type: UserIdentificationAssociationType::CUSTOM_1)
+     * int32[3]: 1   (1st value: UserIdentificationAssociationValue::ASSOCIATED_CURRENT_USER)
+     *
+     * Notice that the set request adds associations, but doesn't remove the existing ones. In the
+     * example above, the end state would be 2 associations (FOB and CUSTOM_1). If we wanted to
+     * associate the user with just CUSTOM_1 but not FOB, then the request should have been:
+     *
+     * int32[0]: 43  // request id
+     * int32[1]: 10  (Android user id)
+     * int32[2]: 2   (number of types set)
+     * int32[3]: 1   (1st type: UserIdentificationAssociationType::KEY_FOB)
+     * int32[4]: 2   (1st value: UserIdentificationAssociationValue::DISASSOCIATE_CURRENT_USER)
+     * int32[5]: 101 (2nd type: UserIdentificationAssociationType::CUSTOM_1)
+     * int32[6]: 1   (2nd value: UserIdentificationAssociationValue::ASSOCIATE_CURRENT_USER)

+     * For each combination (and their subsets) of camera device ids returned by
+     * getConcurrentStreamingCameraIds(): If only the mandatory combinations can
+     * be supported concurrently by each device, then the resource costs must

+     * For guaranteed concurrent camera operation, the camera framework must call

+     * any streams on them. This gives the camera HAL process an opportunity to potentially
+     * distribute hardware resources better before stream configuration.
+     *
+     * Due to potential hardware constraints around internal switching of physical camera devices,
+     * a device's complete ZOOM_RATIO_RANGE(if supported), may not apply during concurrent
+     * operation. If ZOOM_RATIO is supported, camera HALs must ensure ZOOM_RATIO_RANGE of

+     *
+     * ------------ Overview -----------------------------------
+     * Gralloc 4 adds support for getting and setting buffer metadata on a buffer.
+     *
+     * To get buffer metadata, the client passes in a buffer handle and a token that
+     * represents the type of buffer metadata they would like to get. IMapper returns
+     * a byte stream that contains the buffer metadata. To set the buffer metadata, the
+     * client passes in a buffer handle and a token that represents the type of buffer
+     * metadata they would like to set and a byte stream that contains the buffer metadata
+     * they are setting.
+     *
+     * Buffer metadata is global for a buffer. When the metadata is set on the buffer
+     * in a process, the updated metadata should be available to all other processes.
+     * Please see "Storing and Propagating Metadata" below for more details.
+     *
+     * The getter and setter functions have been optimized for easy vendor extension.
+     * They do not require a formal HIDL extension to add support for getting and setting
+     * vendor defined buffer metadata. In order to allow easy extension, the types used
+     * here are not typical HIDL types. See "Buffer Metadata Token" and
+     * "Buffer Metadata Stream" below for more details.
+     *
+     * ------------ Storing and Propagating Metadata -----------
+     * Buffer metadata must be global. Any changes to the metadata must be propagated
+     * to all other processes immediately. Vendors may chose how they would like support
+     * this functionality.
+     *
+     * We recommend supporting this functionality by allocating an extra page of shared
+     * memory and storing it in the buffer's native_handle_t. The buffer metadata can
+     * be stored in the extra page of shared memory. Set operations are automatically
+     * propagated to all other processes.
+     *
+     * ------------ Buffer Metadata Synchronization ------------
+     * There are no explicit buffer metadata synchronization primitives. Many devices
+     * before gralloc 4 already support getting and setting of global buffer metadata
+     * with no explicit synchronization primitives. Adding synchronization primitives
+     * would just add unnecessary complexity.
+     *
+     * The general rule is if a process has permission to write to a buffer, they
+     * have permission to write to the buffer's metadata. If a process has permission
+     * to read from a buffer, they have permission to read the buffer's metadata.
+     *
+     * There is one exception to this rule. Fences CANNOT be used to protect a buffer's
+     * metadata. A process should finish writing to a buffer's metadata before
+     * sending the buffer to another process that will read or write to the buffer.
+     * This exception is needed because sometimes userspace needs to read the
+     * buffer's metadata before the buffer's contents are ready.
+     *
+     * As a simple example: an app renders to a buffer and then displays the buffer.
+     * In this example when the app renders to the buffer, both the buffer and its
+     * metadata need to be updated. The app's process queues up its work on the GPU
+     * and gets back an acquire fence. The app's process must update the buffer's
+     * metadata before enqueuing the buffer to SurfaceFlinger. The app process CANNOT
+     * update the buffer's metadata after enqueuing the buffer. When HardwareComposer
+     * receives the buffer, it is immediately safe to read the buffer's metadata
+     * and use it to program the display driver. To read the buffer's contents,
+     * display driver must still wait on the acquire fence.
+     *
+     * ------------ Buffer Metadata Token ----------------------
+     * In order to allow arbitrary vendor defined metadata, we could not use a
+     * HIDL enum as the buffer metadata token. Extending a HIDL enum requires a full
+     * HIDL extension. We also could not use a simple non-HIDL enum because vendor
+     * defined enums from different vendors could collide. Instead we have defined
+     * a struct that has a string representing the enum type and an int that
+     * represents the enum value. The string protects different enum values from
+     * colliding.
+     *
+     * The token struct (MetadataType) is defined as a HIDL struct since it
+     * is passed into a HIDL function. The standard buffer metadata types are NOT
+     * defined as a HIDL enum because it would have required a new IMapper version
+     * just to add future standard buffer metadata types. By putting the enum in the
+     * stable AIDL (hardware/interfaces/graphics/common/aidl/android/hardware/
+     * graphics/common/StandardMetadataType.aidl), vendors will be able to optionally
+     * choose to support future standard buffer metadata types without upgrading
+     * HIDL versions. For more information see the description of "struct MetadataType".
+     *
+     * ------------ Buffer Metadata Stream ---------------------
+     * The buffer metadata is get and set as a byte stream (vec<uint8_t>). By getting
+     * and setting buffer metadata as a byte stream, vendors can use the standard
+     * getters and setter functions defined here. Vendors do NOT need to add their own
+     * getters and setter functions for each new type of buffer metadata.
+     *
+     * Converting buffer metadata into a byte stream can be non-trivial. For the standard
+     * buffer metadata types defined in StandardMetadataType.aidl, there are also
+     * support functions that will encode the buffer metadata into a byte stream
+     * and decode the buffer metadata from a byte stream. We STRONGLY recommend using
+     * these support functions. The framework will use them when getting and setting
+     * metadata. The support functions are defined in
+     * frameworks/native/libs/gralloc/types/include/gralloctypes/Gralloc4.h.

+# Implement the 2.1 HAL instead!
+
+It is strongly recommended that you implement the 2.1 HAL directly. See
+`hardware/interfaces/health/2.1/README.md` for more details.
+
+# Implement Health 1.0 HAL
+
+1. Install common binderized service. The binderized service `dlopen()`s
+   passthrough implementations on the device, so there is no need to write
+   your own.
+
+    ```mk
+    # Install default binderized implementation to vendor.
+    PRODUCT_PACKAGES += android.hardware.health@1.0-service
+    ```
+
+1. Add proper VINTF manifest entry to your device manifest. Example:
+
+    ```xml
+    <hal format="hidl">
+        <name>android.hardware.health</name>
+        <transport>hwbinder</transport>
+        <version>1.0</version>
+        <interface>
+            <name>IHealth</name>
+            <instance>default</instance>
+        </interface>
+    </hal>
+    ```
+
+1. Install the proper passthrough implemetation.
+
+    1. If you want to use the default implementation (with default `libhealthd`),
+       add the following to `device.mk`:
+
+        ```mk
+        PRODUCT_PACKAGES += \
+            android.hardware.health@1.0-impl
+        ```
+
+    1. Otherwise, if you have a customized `libhealthd.<board>`:
+
+        1. Define your passthrough implementation. Example (replace `<device>`
+           and `<board>` accordingly):
+
+            ```bp
+            cc_library_shared {
+                name: "android.hardware.health@1.0-impl-<device>",
+                vendor: true,
+                relative_install_path: "hw",
+
+                static_libs: [
+                    "android.hardware.health@1.0-impl-helper",
+                    "android.hardware.health@1.0-convert",
+                    "libhealthd.<board>",
+                ],
+            }
+            ```
+
+        1. Add to `device.mk`.

+# Implementing Health 2.1 HAL
+
+1. Install common binderized service. The binderized service `dlopen()`s
+   passthrough implementations on the device, so there is no need to write
+   your own.
+
+    ```mk
+    # Install default binderized implementation to vendor.
+    PRODUCT_PACKAGES += android.hardware.health@2.1-service
+    ```
+
+1. Delete existing VINTF manifest entry. Search for `android.hardware.health` in
+   your device manifest, and delete the whole `<hal>` entry for older versions
+   of the HAL. Instead, when `android.hardware.health@2.1-service` is installed,
+   a VINTF manifest fragment is installed to `/vendor/etc/vintf`, so there is
+   no need to manually specify it in your device manifest. See
+   [Manifest fragments](https://source.android.com/devices/architecture/vintf/objects#manifest-fragments)
+   for details.
+
+1. Install the proper passthrough implemetation.
+
+    1. If you want to use default implementation:
+
+        ```mk
+        # Install default passthrough implementation to vendor.
+        PRODUCT_PACKAGES += android.hardware.health@2.1-impl
+
+        # For non-A/B devices, install default passthrough implementation to recovery.
+        PRODUCT_PACKAGES += android.hardware.health@2.1-impl.recovery
+        ```
+
+        You are done. Otherwise, go to the next step.
+
+    1. If you want to write your own implementation,
+
+        1. Copy skeleton implementation from the [appendix](#impl).
+
+        1. Modify the implementation to suit your needs.
+
+            * If you have a board or device specific `libhealthd`, see
+              [Upgrading with  a customized libhealthd](#update-from-1-0).
+            * If you are upgrading from 1.0 health HAL, see
+              [Upgrading from Health HAL 1.0](#update-from-1-0).
+            * If you are upgrading from a customized 2.0 health HAL
+              implementation, See
+              [Upgrading from Health HAL 2.0](#update-from-2-0).
+
+        1. [Install the implementation](#install).
+
+        1. [Update necessary SELinux permissions](#selinux).
+
+        1. [Fix `/charger` symlink](#charger-symlink).
+
+# Upgrading with a customized libhealthd or from Health HAL 1.0 {#update-from-1-0}
+
+`libhealthd` contains two functions: `healthd_board_init()` and
+`healthd_board_battery_update()`. Similarly, Health HAL 1.0 contains `init()`
+and `update()`, with an additional `energyCounter()` function.
+
+* `healthd_board_init()` / `@1.0::IHealth.init()` should be called before
+  passing the `healthd_config` struct to your `HealthImpl` class. See
+  `HIDL_FETCH_IHealth` in [`HealthImpl.cpp`](#health_impl_cpp).
+
+* `healthd_board_battery_update()` / `@1.0::IHealth.update()` should be called
+  in `HealthImpl::UpdateHealthInfo()`. Example:
+
+  ```c++
+  void HealthImpl::UpdateHealthInfo(HealthInfo* health_info) {
+      struct BatteryProperties props;
+      convertFromHealthInfo(health_info->legacy.legacy, &props);
+      healthd_board_battery_update(&props);
+      convertToHealthInfo(&props, health_info->legacy.legacy);
+  }
+  ```
+  For efficiency, you should move code in `healthd_board_battery_update` to
+  `HealthImpl::UpdateHealthInfo` and modify `health_info` directly to avoid
+  conversion to `BatteryProperties`.
+
+* Code for `@1.0::IHealth.energyCounter()` should be moved to
+  `HealthImpl::getEnergyCounter()`. Example:
+
+  ```c++
+  Return<void> Health::getEnergyCounter(getEnergyCounter_cb _hidl_cb) {
+      int64_t energy = /* ... */;
+      _hidl_cb(Result::SUCCESS, energy);
+      return Void();
+  }
+  ```
+
+# Upgrading from Health HAL 2.0 {#update-from-2-0}
+
+* If you have implemented `healthd_board_init()` and/or
+  `healthd_board_battery_update()` (instead of using `libhealthd.default`),
+  see [the section above](#update-from-1-0)
+  for instructions to convert them.
+
+* If you have implemented `get_storage_info()` and/or `get_disk_stats()`
+  (instead of using libhealthstoragedefault), implement `HealthImpl::getDiskStats`
+  and/or `HealthImpl::getStorageInfo` directly. There is no need to override
+  `HealthImpl::getHealthInfo` or `HealthImpl::getHealthInfo_2_1` because they call
+  `getDiskStats` and `getStorageInfo` to retrieve storage information.
+
+# Install the implementation {#install}
+
+In `device.mk`:
+
+```mk
+# Install the passthrough implementation to vendor.
+PRODUCT_PACKAGES += android.hardware.health@2.1-impl-<device>
+
+# For non-A/B devices, also install the passthrough implementation to recovery.
+PRODUCT_PACKAGES += android.hardware.health@2.1-impl-<device>.recovery
+```
+
+# Update necessary SELinux permissions {#selinux}
+
+For example (replace `<device>` with the device name):
+```
+# device/<manufacturer>/<device>/sepolicy/vendor/hal_health_default.te
+# Add device specific permissions to hal_health_default domain, especially
+# if a device-specific libhealthd is used and/or device-specific storage related
+# APIs are implemented.
+```
+
+# Fix `/charger` symlink {#charger-symlink}
+If you are using `/charger` in your `init.rc` scripts, it is recommended
+(required for devices running in Android R) that the path is changed to
+`/system/bin/charger` instead.
+
+Search for `service charger` in your device configuration directory to see if
+this change applies to your device. Below is an example of how the script should
+look like:
+
+```
+service charger /system/bin/charger
+    class charger
+    user system
+    group system wakelock input
+    capabilities SYS_BOOT
+    file /dev/kmsg w
+    file /sys/fs/pstore/console-ramoops-0 r
+    file /sys/fs/pstore/console-ramoops r
+    file /proc/last_kmsg r
+```

+     *  3. The map must contain a tstr key "nameSpaces" whose value contains a map, as described in
+     *     the example below.
+     *
+     * If these requirements are not met the startRetrieval() call fails with

+     * For the readerSignature parameter, this can either be empty or if non-empty it
+     * must be a COSE_Sign1 where the payload is the bytes of the

+     *       "ReaderAuthentication",

+     * in 'draft-ietf-cose-x509-04'). There will be at least one certificate in said element
+     * and there may be more (and if so, each certificate must be signed by its successor).
+     * This is checked and if the check fails the call fails with
+     * STATUS_READER_SIGNATURE_CHECK_FAILED.
+     *
+     * The SessionTranscript CBOR is conveyed in the sessionTranscript parameter. It
+     * is permissible for this to be empty in which case the readerSignature parameter
+     * must also be empty. If this is not the case, the call fails with STATUS_FAILED.
+     *
+     * If the SessionTranscript CBOR is not empty, the X and Y coordinates of the public
+     * part of the key-pair previously generated by createEphemeralKeyPair() must appear
+     * somewhere in the bytes of the CBOR. Each of these coordinates must appear encoded
+     * with the most significant bits first and use the exact amount of bits indicated by
+     * the key size of the ephemeral keys. For example, if the ephemeral key is using the
+     * P-256 curve then the 32 bytes for the X coordinate encoded with the most significant
+     * bits first must appear somewhere in the CBOR and ditto for the 32 bytes for the Y
+     * coordinate. If this is not satisfied, the call fails with
+     * STATUS_EPHEMERAL_PUBLIC_KEY_NOT_FOUND.

+/**
+ * IIdentityCredentialStore provides an interface to a secure store for user identity documents.
+ * This HAL is deliberately fairly general and abstract.  To the extent possible, specification of
+ * the message formats and semantics of communication with credential verification devices and
+ * issuing authorities (IAs) is out of scope for this HAL.  It provides the interface with secure
+ * storage but a credential-specific Android application will be required to implement the
+ * presentation and verification protocols and processes appropriate for the specific credential
+ * type.
+ *
+ * The design of this HAL makes few assumptions about the underlying secure hardware.  In particular
+ * it does not assume that the secure hardware has any storage beyond that needed for a persistent,
+ * hardware-bound AES-128 key.  However, its design allows the use of secure hardware that does have
+ * storage, specifically to enable "direct access".  Most often credentials will be accessed through
+ * this HAL and through the Android layers above it but that requires that the Android device be
+ * powered up and fully functional.  It is desirable to allow identity credential usage when the
+ * Android device's battery is too low to boot the Android operating system, so direct access to the
+ * secure hardware via NFC may allow data retrieval, if the secure hardware chooses to implement it.
+ * Definition of how data is retrieved in low power mode is explicitly out of scope for this HAL
+ * specification; it's up to the relevant identity credential standards to define.
+ *
+ * The 'default' HAL instance is explicitly not for direct access and the 'direct_access' HAL
+ * instance - if available - is for direct access. Applications are expected to provision their
+ * credential to both instances (and the contents may differ), not just one of them.
+ *
+ * Multiple credentials can be created.  Each credential comprises:
+ *
+ * - A document type, which is a UTF-8 string of at most 256 bytes.
+ *
+ * - A set of namespaces, which serve to disambiguate value names.  Namespaces are UTF-8 strings of
+ *   up to 256 bytes in length (most should be much shorter).  It is recommended that namespaces be
+ *   structured as reverse domain names so that IANA effectively serves as the namespace registrar.
+ *
+ * - For each namespase, a set of name/value pairs, each with an associated set of access control
+ *   profile IDs.  Names are UTF-8 strings of up to 256 bytes in length (most should be much
+ *   shorter).  Values stored must be encoded as CBOR (https://tools.ietf.org/html/rfc7049) and
+ *   the encoded size is is limited to at most 512 KiB.
+ *
+ * - A set of access control profiles, each with a profile ID and a specification of the
+ *   conditions which satisfy the profile's requirements.
+ *
+ * - An asymmetric key pair which is used to authenticate the credential to the IA, called the
+ *   CredentialKey. This key is attested to by the secure hardware using Android Keystore
+ *   attestation (https://source.android.com/security/keystore/attestation). See
+ *   getAttestationCertificate() in the IWritableIdentityCredential for more information.
+ *
+ * - A set of zero or more named reader authentication public keys, which are used to authenticate
+ *   an authorized reader to the credential.
+ *
+ * - A set of named signing keys, which are used to sign collections of values and session
+ *   transcripts.
+ *
+ * Cryptographic notation:
+ *
+ * Throughout this HAL, cryptographic operations are specified in detail.  To avoid repeating the
+ * definition of the notation, it's specified here.  It is assumed that the reader is familiar with
+ * standard cryptographic algorithms and constructs.
+ *
+ *     AES-GCM-ENC(K, N, D, A) represents AES-GCM encryption with key 'K', nonce 'N', additional
+ *         authenticated data 'A' and data 'D'.  The nonce is usually specified as 'R', meaning 12
+ *         random bytes.  The nonce is always 12 bytes and is prepended to the ciphertext. The GCM
+ *         tag is 16 bytes, appended to the ciphertext.  AES-GCM-DEC with the same argument notation
+ *         represents the corresponding decryption operation.
+ *
+ *    ECDSA(K, D) represents ECDSA signing of data 'D' with key 'K'.
+ *
+ *    || represents concatenation
+ *
+ *    {} represents an empty input; 0 bytes of data.
+ *
+ *    HBK represents a device-unique, hardware-bound AES-128 key which exists only in secure
+ *        hardware, except for "test" credential stores (see createCredential(), below).  For test
+ *        stores, an all-zero value is used in place of the HBK.
+ *
+ * Data encoding notation:
+ *
+ * Various fields need to be encoded as precisely-specified byte arrays.  Where existing standards
+ * define appropriate encodings, those are used.  For example, X.509 certificates.  Where new
+ * encodings are needed, CBOR is used.  CBOR maps are described in CDDL notation
+ * (https://tools.ietf.org/html/rfc8610).
+ *
+ * All binder calls in the HAL may return a ServiceSpecificException with statuses from the
+ * STATUS_* integers defined in this interface. Each method states which status can be returned
+ * and under which circumstances.

+CppBor: A Modern C++ CBOR Parser and Generator
+==============================================
+
+CppBor provides a natural and easy-to-use syntax for constructing and
+parsing CBOR messages.  It does not (yet) support all features of
+CBOR, nor (yet) support validation against CDDL schemata, though both
+are planned.  CBOR features that aren't supported include:
+
+* Indefinite length values
+* Semantic tagging
+* Floating point
+
+CppBor requires C++-17.
+
+## CBOR representation
+
+CppBor represents CBOR data items as instances of the `Item` class or,
+more precisely, as instances of subclasses of `Item`, since `Item` is a
+pure interface.  The subclasses of `Item` correspond almost one-to-one
+with CBOR major types, and are named to match the CDDL names to which
+they correspond.  They are:
+
+* `Uint` corresponds to major type 0, and can hold unsigned integers
+  up through (2^64 - 1).
+* `Nint` corresponds to major type 1.  It can only hold values from -1
+  to -(2^63 - 1), since it's internal representation is an int64_t.
+  This can be fixed, but it seems unlikely that applications will need
+  the omitted range from -(2^63) to (2^64 - 1), since it's
+  inconvenient to represent them in many programming languages.
+* `Int` is an abstract base of `Uint` and `Nint` that facilitates
+  working with all signed integers representable with int64_t.
+* `Bstr` corresponds to major type 2, a byte string.
+* `Tstr` corresponds to major type 3, a text string.
+* `Array` corresponds to major type 4, an Array.  It holds a
+  variable-length array of `Item`s.
+* `Map` corresponds to major type 5, a Map.  It holds a
+  variable-length array of pairs of `Item`s.
+* `Simple` corresponds to major type 7.  It's an abstract class since
+  items require more specific type.
+* `Bool` is the only currently-implemented subclass of `Simple`.
+
+Note that major type 6, semantic tag, is not yet implemented.
+
+In practice, users of CppBor will rarely use most of these classes
+when generating CBOR encodings.  This is because CppBor provides
+straightforward conversions from the obvious normal C++ types.
+Specifically, the following conversions are provided in appropriate
+contexts:
+
+* Signed and unsigned integers convert to `Uint` or `Nint`, as
+  appropriate.
+* `std::string`, `std::string_view`, `const char*` and
+  `std::pair<char iterator, char iterator>` convert to `Tstr`.
+* `std::vector<uint8_t>`, `std::pair<uint8_t iterator, uint8_t
+  iterator>` and `std::pair<uint8_t*, size_t>` convert to `Bstr`.
+* `bool` converts to `Bool`.
+
+## CBOR generation
+
+### Complete tree generation
+
+The set of `encode` methods in `Item` provide the interface for
+producing encoded CBOR.  The basic process for "complete tree"
+generation (as opposed to "incremental" generation, which is discussed
+below) is to construct an `Item` which models the data to be encoded,
+and then call one of the `encode` methods, whichever is convenient for
+the encoding destination.  A trivial example:
+
+```
+cppbor::Uint val(0);
+std::vector<uint8_t> encoding = val.encode();
+```
+
+    It's relatively rare that single values are encoded as above.  More often, the
+    "root" data item will be an `Array` or `Map` which contains a more complex structure.For example
+    :
+
+``` using cppbor::Map;
+using cppbor::Array;
+
+std::vector<uint8_t> vec =  // ...
+    Map val("key1", Array(Map("key_a", 99 "key_b", vec), "foo"), "key2", true);
+std::vector<uint8_t> encoding = val.encode();
+```
+
+This creates a map with two entries, with `Tstr` keys "Outer1" and
+"Outer2", respectively.  The "Outer1" entry has as its value an
+`Array` containing a `Map` and a `Tstr`.  The "Outer2" entry has a
+`Bool` value.
+
+This example demonstrates how automatic conversion of C++ types to
+CppBor `Item` subclass instances is done.  Where the caller provides a
+C++ or C string, a `Tstr` entry is added.  Where the caller provides
+an integer literal or variable, a `Uint` or `Nint` is added, depending
+on whether the value is positive or negative.
+
+As an alternative, a more fluent-style API is provided for building up
+structures.  For example:
+
+```
+using cppbor::Map;
+using cppbor::Array;
+
+std::vector<uint8_t> vec =  // ...
+    Map val();
+val.add("key1", Array().add(Map().add("key_a", 99).add("key_b", vec)).add("foo")).add("key2", true);
+std::vector<uint8_t> encoding = val.encode();
+```
+
+    An advantage of this interface over the constructor -
+    based creation approach above is that it need not be done all at once
+        .The `add` methods return a reference to the object added to to allow calls to be chained,
+    but chaining is not necessary; calls can be made
+sequentially, as the data to add is available.
+
+#### `encode` methods
+
+There are several variations of `Item::encode`, all of which
+accomplish the same task but output the encoded data in different
+ways, and with somewhat different performance characteristics.  The
+provided options are:
+
+* `bool encode(uint8\_t** pos, const uint8\_t* end)` encodes into the
+  buffer referenced by the range [`*pos`, end).  `*pos` is moved.  If
+  the encoding runs out of buffer space before finishing, the method
+  returns false.  This is the most efficient way to encode, into an
+  already-allocated buffer.
+* `void encode(EncodeCallback encodeCallback)` calls `encodeCallback`
+  for each encoded byte.  It's the responsibility of the implementor
+  of the callback to behave safely in the event that the output buffer
+  (if applicable) is exhausted.  This is less efficient than the prior
+  method because it imposes an additional function call for each byte.
+* `template </*...*/> void encode(OutputIterator i)`
+  encodes into the provided iterator.  SFINAE ensures that the
+  template doesn't match for non-iterators.  The implementation
+  actually uses the callback-based method, plus has whatever overhead
+  the iterator adds.
+* `std::vector<uint8_t> encode()` creates a new std::vector, reserves
+  sufficient capacity to hold the encoding, and inserts the encoded
+  bytes with a std::pushback_iterator and the previous method.
+* `std::string toString()` does the same as the previous method, but
+  returns a string instead of a vector.
+
+### Incremental generation
+
+Incremental generation requires deeper understanding of CBOR, because
+the library can't do as much to ensure that the output is valid.  The
+basic tool for intcremental generation is the `encodeHeader`
+function.  There are two variations, one which writes into a buffer,
+and one which uses a callback.  Both simply write out the bytes of a
+header.  To construct the same map as in the above examples,
+incrementally, one might write:
+
+```
+using namespace cppbor;  // For example brevity
+
+std::vector encoding;
+auto iter = std::back_inserter(result);
+encodeHeader(MAP, 2 /* # of map entries */, iter);
+std::string s = "key1";
+encodeHeader(TSTR, s.size(), iter);
+std::copy(s.begin(), s.end(), iter);
+encodeHeader(ARRAY, 2 /* # of array entries */, iter);
+Map().add("key_a", 99).add("key_b", vec).encode(iter)
+s = "foo";
+encodeHeader(TSTR, foo.size(), iter);
+std::copy(s.begin(), s.end(), iter);
+s = "key2";
+encodeHeader(TSTR, foo.size(), iter);
+std::copy(s.begin(), s.end(), iter);
+encodeHeader(SIMPLE, TRUE, iter);
+```
+
+As the above example demonstrates, the styles can be mixed -- Note the
+creation and encoding of the inner Map using the fluent style.
+
+## Parsing
+
+CppBor also supports parsing of encoded CBOR data, with the same
+feature set as encoding.  There are two basic approaches to parsing,
+"full" and "stream"
+
+### Full parsing
+
+Full parsing means completely parsing a (possibly-compound) data
+item from a byte buffer.  The `parse` functions that do not take a
+`ParseClient` pointer do this.  They return a `ParseResult` which is a
+tuple of three values:
+
+* std::unique_ptr<Item> that points to the parsed item, or is nullptr
+  if there was a parse error.
+* const uint8_t* that points to the byte after the end of the decoded
+  item, or to the first unparseable byte in the event of an error.
+* std::string that is empty on success or contains an error message if
+  a parse error occurred.
+
+Assuming a successful parse, you can then use `Item::type()` to
+discover the type of the parsed item (e.g. MAP), and then use the
+appropriate `Item::as*()` method (e.g. `Item::asMap()`) to get a
+pointer to an interface which allows you to retrieve specific values.
+
+### Stream parsing
+
+Stream parsing is more complex, but more flexible.  To use
+StreamParsing, you must create your own subclass of `ParseClient` and
+call one of the `parse` functions that accepts it.  See the
+`ParseClient` methods docstrings for details.
+
+One unusual feature of stream parsing is that the `ParseClient`
+callback methods not only provide the parsed Item, but also pointers
+to the portion of the buffer that encode that Item.  This is useful
+if, for example, you want to find an element inside of a structure,
+and then copy the encoding of that sub-structure, without bothering to
+parse the rest.
+
+The full parser is implemented with the stream parser.

+# Keymaster Benchmark
+
+The Keymaster Benchmark is a standalone tool for measuring the performance of keymaster implementations.
+
+## Building
+
+Build:
+`m  keymaster_benchmark`
+
+Transfer to device/emulator:
+`adb sync data`
+
+The benchmark executable should will be located at `data/benchmarktest/keymaster_benchmark/keymaster_benchmark` on the device.
+
+## Usage
+
+Keymaster 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 allow specification of the keymaster service name, e.g. specify `--service_name=strongbox` to benchmark strongbox.

+ * @4.1::IKeymasterDevice is a minor extension to @4.0::IKeymasterDevice.  It adds support for

+ * - Partial hardware enforcment of UNLOCKED_DEVICE_REQUIRED keys;
+ * - Device-unique attestaion;
+ * - Early boot only keys;
+ * - Better cleanup of operations when clients die without completing or aborting them.
+ *
+ * @4.1::IKeymasterDevice::attestKey() must produce attestations with keymasterVersion 41.  An
+ * oversight in the original numbering left no room for minor versions, so starting with 4.1 the
+ * versions will be numbered as major_version * 10 + minor version.  The addition of new attestable
+ * tags changes the attestation format again, slightly, so the attestationVersion must be 4.

+     * the IKeymasterDevice 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.
+     *
+     * Note that the IKeymasterDevice 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 enformcement logic in IKeymasterDevice.  So from the
+     * IKeymasterDevice perspective, any user unlock unlocks all UNLOCKED_DEVICE_REQUIRED keys.
+     * Keystore will continue enforcing the per-user device locking.
+     *
+     * @param passwordOnly specifies whether the device must be unlocked with a password, rather
+     * than a biometric, before UNLOCKED_DEVICE_REQUIRED keys can be used.
+     *
+     * @param verificationToken is used by StrongBox implementations of IKeymasterDevice.  It
+     * provides the StrongBox IKeymasterDevice 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 verificationToken, the device is still considered to be locked.
+     * Crucially, if a StrongBox IKeymasterDevice receives a deviceLocked() call with a verification
+     * token timestamp that is less than the timestamp in the last deviceLocked() call, it must
+     * ignore the new timestamp.  TEE IKeymasterDevice implementations will receive an empty
+     * verificationToken (zero values and empty vectors) and should use their own clock as the
+     * device-lock time.

+ * implementation that is used to wrap pre-HIDL keymaster implementations, and Keymaster3 will wrap
+ * that.
+ *
+ * The reason for adding this additional layer, rather than simply using the latest HAL directly and
+ * subclassing it to wrap any older HAL, is because this provides a place to put additional methods
+ * which clients can use when they need to distinguish between different underlying HAL versions,
+ * while still having to use only the latest interface.  Plus it's a handy place to keep some
+ * convenience methods.

 This folder includes test fixtures that tests aspects common to all omx compatible components. For instance, port enabling/disabling, enumerating port formats, state transitions, flush, ..., stay common to all components irrespective of the service they offer. Test fixtures here are directed towards testing these (omx core). Every standard OMX compatible component is expected to pass these tests.

-/**
- * The CallbackBase class is used internally by the NeuralNetworks runtime to
- * synchronize between different threads. An asynchronous task is launched
- * paired with a callback object. When a client thread requires the output being
- * generated by the asynchronous task, the client thread can wait for the result
- * and be blocked until it has completed or a timeout condition has been
- * reached. Any wait* may safely be called concurrently, even on the same
- * callback object. When the asynchronous task has finished its workload, it
- * must immediately call "notify". If the asynchronous task has failed to launch,
- * the function that tried to launch the asynchronous task must immediately call
- * "notify". This "notify" call awakens any client threads waiting on the
- * callback object.
- *
- * The CallbackBase class implements some of the base synchronization common to
- * both PrepareModelCallback and ExecutionCallback. For consistency, any HIDL
- * callback class must inherit from CallbackBase as well as the HIDL callback
- * interface it implements.
- *
- * This class exists to enable synchronization across HIDL. When synchronization
- * is only required in the same process, consider using std::future, std::mutex,
- * std::condition_variable, or std::experimental::latch instead.

+     *
+     * The file descriptors must be opened with read and write permission. A

+     * asynchronous preparation has finished. The driver must dup a file
+     * descriptor if it wants to get access to the cache file later.
+     *
+     * The model is prepared asynchronously with respect to the caller. The
+     * prepareModel function must verify the inputs to the preparedModel
+     * function related to preparing the model (as opposed to saving the
+     * prepared model to cache) are correct. If there is an error, prepareModel
+     * must immediately invoke the callback with the appropriate ErrorStatus
+     * value and nullptr for the IPreparedModel, then return with the same
+     * ErrorStatus. If the inputs to the prepareModel function that are related
+     * to preparing the model are valid and there is no error, prepareModel must
+     * launch an asynchronous task to prepare the model in the background, and
+     * immediately return from prepareModel with ErrorStatus::NONE. If the
+     * asynchronous task fails to launch, prepareModel must immediately invoke
+     * the callback with ErrorStatus::GENERAL_FAILURE and nullptr for the
+     * IPreparedModel, then return with ErrorStatus::GENERAL_FAILURE.
+     *
+     * When the asynchronous task has finished preparing the model, it must
+     * immediately invoke the callback function provided as an input to
+     * prepareModel. If the model was prepared successfully, the callback object
+     * must be invoked with an error status of ErrorStatus::NONE and the
+     * produced IPreparedModel object. If an error occurred preparing the model,
+     * the callback object must be invoked with the appropriate ErrorStatus
+     * value and nullptr for the IPreparedModel.
+     *
+     * The model is prepared with a priority. This priority is relative to other
+     * prepared models owned by the same client. Higher priority executions may
+     * use more compute resources than lower priority executions, and may
+     * preempt or starve lower priority executions.

+     * prepareModel_1_3 can be called with an optional deadline. If the model

+     * ErrorStatus::MISSED_DEADLINE_PERSISTENT} may be returned. The error due
+     * to an abort must be sent the same way as other errors, described above.
+     *
+     * Optionally, the driver may save the prepared model to cache during the
+     * asynchronous preparation. Any error that occurs when saving to cache must
+     * not affect the status of preparing the model. Even if the input arguments
+     * related to the cache may be invalid, or the driver may fail to save to
+     * cache, the prepareModel function must finish preparing the model. The
+     * driver may choose not to save to cache even if the caching information is
+     * provided and valid.
+     *
+     * The only information that may be unknown to the model at this stage is
+     * the shape of the tensors, which may only be known at execution time. As
+     * such, some driver services may return partially prepared models, where
+     * the prepared model may only be finished when it is paired with a set of
+     * inputs to the model. Note that the same prepared model object may be used
+     * with different shapes of inputs on different (possibly concurrent)
+     * executions.

+     * This Op unrolls the input along the sequence dimension, and implements
+     * the following operation for each element in the sequence s =
+     * 1...sequence_length:
+     *   fw_outputs[s] = fw_state = activation(inputs[s] * fw_input_weights’ +
+     *          fw_state * fw_recurrent_weights’ + fw_bias)

+     * Where:
+     * * “{fw,bw}_input_weights” is a weight matrix that multiplies the inputs;
+     * * “{fw,bw}_recurrent_weights” is a weight matrix that multiplies the
+     *    current “state” which itself is the output from the previous time step

+     *   argument (if not “NONE”).
+     *
+     * The op supports cross-linking via an auxiliary input. Regular cell feeds

+     *    at room temperature (roughly 22 Celsius), without hitting thermal
+     *    throttling.
+     * 4) After setting those clocks, set the system property

+     *    cycle. It is expected that in FIXED_PERFORMANCE mode, unless there is

+"EARLY_BOOT_ONLY" keys be usable when this test runs. In order to accomplish
+this, a build of "vold" that omits the call to "earlyBootEnded()" function
+should be made. Then these DISABLED tests may be run successfully.

+The CTS test ResumeOnRebootHostTests will test the functionality without a

+     *
+     * The Fast Message Queues (FMQ) that are used to send data between the
+     * framework and the HAL. The callback is used by the HAL to notify the
+     * framework of asynchronous events, such as a dynamic sensor connection.
+     *
+     * The Event FMQ is used to transport sensor events from the HAL to the
+     * framework. The Event FMQ is created using the eventQueueDescriptor.
+     * Data may only be written to the Event FMQ. Data must not be read from
+     * the Event FMQ since the framework is the only reader. Upon receiving
+     * sensor events, the HAL writes the sensor events to the Event FMQ.
+     *
+     * Once the HAL is finished writing sensor events to the Event FMQ, the HAL
+     * must notify the framework that sensor events are available to be read and
+     * processed. This is accomplished by either:
+     *     1) Calling the Event FMQ’s EventFlag::wake() function with
+              EventQueueFlagBits::READ_AND_PROCESS
+     *     2) Setting the write notification in the Event FMQ’s writeBlocking()
+     *        function to EventQueueFlagBits::READ_AND_PROCESS.
+     *
+     * If the Event FMQ’s writeBlocking() function is used, the read
+     * notification must be set to EventQueueFlagBits::EVENTS_READ in order to
+     * be notified and unblocked when the framework has successfully read events
+     * from the Event FMQ.
+     *
+     * The Wake Lock FMQ is used by the framework to notify the HAL when it is
+     * safe to release its wake_lock. When the framework receives WAKE_UP events
+     * from the Event FMQ and the framework has acquired a wake_lock, the
+     * framework must write the number of WAKE_UP events processed to the Wake
+     * Lock FMQ. When the HAL reads the data from the Wake Lock FMQ, the HAL
+     * decrements its current count of unprocessed WAKE_UP events and releases
+     * its wake_lock if the current count of unprocessed WAKE_UP events is
+     * zero. It is important to note that the HAL must acquire the wake lock and
+     * update its internal state regarding the number of outstanding WAKE_UP
+     * events _before_ posting the event to the Wake Lock FMQ, in order to avoid
+     * a race condition that can lead to loss of wake lock synchronization with
+     * the framework.
+     *
+     * The framework must use the WakeLockQueueFlagBits::DATA_WRITTEN value to
+     * notify the HAL that data has been written to the Wake Lock FMQ and must
+     * be read by HAL.
+     *
+     * The ISensorsCallback is used by the HAL to notify the framework of
+     * asynchronous events, such as a dynamic sensor connection.
+     *
+     * The name of any wake_lock acquired by the Sensors HAL for WAKE_UP events
+     * must begin with "SensorsHAL_WAKEUP".
+     *
+     * If WAKE_LOCK_TIMEOUT_SECONDS has elapsed since the most recent WAKE_UP
+     * event was written to the Event FMQ without receiving a message on the
+     * Wake Lock FMQ, then any held wake_lock for WAKE_UP events must be
+     * released.
+     *
+     * If either the Event FMQ or the Wake Lock FMQ is already initialized when
+     * initialize is invoked, then both existing FMQs must be discarded and the
+     * new descriptors must be used to create new FMQs within the HAL. The
+     * number of outstanding WAKE_UP events should also be reset to zero, and
+     * any outstanding wake_locks held as a result of WAKE_UP events should be
+     * released.
+     *
+     * All active sensor requests and direct channels must be closed and
+     * properly cleaned up when initialize is called in order to ensure that the
+     * HAL and framework's state is consistent (e.g. after a runtime restart).

+This directory contains a modified version of the default implementation
+provided for sensors HAL 2.0 to support multi-HAL 2.0. It should be used as a
+means to verify the multi-HAL 2.0 implementation can successfully load and
+interact with sub-HALs.
+
+This sub-HAL implementation has two macros that can be used to configure support
+for different sets of sensors. One "SUPPORT_CONTINUOUS_SENSORS", enables
+support for continuous sensors like accel, and gyro whereas the other
+"SUPPORT_ON_CHANGE_SENSORS" enables support for on change sensors like the
+light and proximity sensor. A build target is defined for each of these macros,
+but more targets could be added to support both in one sub-HAL or none at all,
+if necessary.
+
+When built, the library will be written to
+out/target/product/<device>/vendor/lib64/android.hardware.sensors@2.0-fakesubhal.so
+
+Take this .so and place it where the multi-HAL config will cause the HalProxy to
+look and then restart the system server with adb shell stop / adb shell start
+to cause the multi-HAL to restart and attempt to load in the sub-HAL.

-/* The chip may either have a single mode supporting any number of combinations,
- * or a fixed dual-mode (so it involves firmware loading to switch between
- * modes) setting. If there is a need to support more modes, it needs to be
- * implemented manually in WiFi HAL (see changeFirmwareMode in
- * WifiChip::handleChipConfiguration).
- *
- * Supported combinations are defined in device's makefile, for example:
- *    WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
- *    WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
- * What means:
- *    Interface combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
- *                             operations.
- *    Interface combination 2: 1 STA and 2 AP concurrent iface operations.
- *
- * For backward compatibility, the following makefile flags can be used to
- * generate combinations list:
- *  - WIFI_HIDL_FEATURE_DUAL_INTERFACE
- *  - WIFI_HIDL_FEATURE_DISABLE_AP
- *  - WIFI_HIDL_FEATURE_AWARE
- * However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
- * With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
- * two interface combinations:
- *    Interface Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
- *                             concurrent iface operations.
- *    Interface Combination 2: Will support 1 STA and 1 AP concurrent
- *                             iface operations.
- *
- * The only dual-mode configuration supported is for alternating STA and AP
- * mode, that may involve firmware reloading. In such case, there are 2 separate
- * modes of operation with 1 interface combination each:
- *    Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
- *                       concurrent iface operations.
- *    Mode 2 (AP mode): Will support 1 AP iface operation.
- *
- * If Aware is enabled, the iface combination will be modified to support either
- * P2P or NAN in place of just P2P.

+ * or a fixed dual-mode (so it involves firmware loading to switch between
+ * modes) setting. If there is a need to support more modes, it needs to be
+ * implemented manually in WiFi HAL (see changeFirmwareMode in
+ * WifiChip::handleChipConfiguration).
+ *
+ * Supported combinations are defined in device's makefile, for example:
+ *    WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
+ *    WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
+ * What means:
+ *    Interface combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
+ *                             operations.
+ *    Interface combination 2: 1 STA and 2 AP concurrent iface operations.
+ *
+ * For backward compatibility, the following makefile flags can be used to
+ * generate combinations list:
+ *  - WIFI_HIDL_FEATURE_DUAL_INTERFACE
+ *  - WIFI_HIDL_FEATURE_DISABLE_AP
+ *  - WIFI_HIDL_FEATURE_AWARE
+ * However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
+ * With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
+ * two interface combinations:
+ *    Interface Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
+ *                             concurrent iface operations.
+ *    Interface Combination 2: Will support 1 STA and 1 AP concurrent
+ *                             iface operations.
+ *
+ * The only dual-mode configuration supported is for alternating STA and AP
+ * mode, that may involve firmware reloading. In such case, there are 2 separate
+ * modes of operation with 1 interface combination each:
+ *    Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
+ *                       concurrent iface operations.
+ *    Mode 2 (AP mode): Will support 1 AP iface operation.
+ *
+ * If Aware is enabled, the iface combination will be modified to support either
+ * P2P or NAN in place of just P2P.
