+     * Description for get(...), set(...) and getFromBufferDescriptorInfo(...)
+     *
+     * ------------ 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.

+     * prepareModelFromCache_1_3 is used to retrieve a prepared model directly from

+     * two types of cache file handles provided to the driver: model cache
+     * and data cache. For more information on the two types of cache handles,
+     * refer to getNumberOfCacheFilesNeeded.
+     *
+     * The file descriptors must be opened with read and write permission. A file may
+     * have any size, and the corresponding file descriptor may have any offset. The
+     * driver must truncate a file to zero size before writing to that file. The file
+     * descriptors may be closed by the client once the 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
+     * prepareModelFromCache_1_3 function must verify the inputs to the
+     * prepareModelFromCache_1_3 function are correct, and that the security-sensitive
+     * cache has not been modified since it was last written by the driver.
+     * If there is an error, or if compilation caching is not supported, or if the
+     * security-sensitive cache has been modified, prepareModelFromCache_1_3 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 prepareModelFromCache_1_3 function are valid, the security-sensitive
+     * cache is not modified, and there is no error, prepareModelFromCache_1_3 must launch an
+     * asynchronous task to prepare the model in the background, and immediately return
+     * from prepareModelFromCache_1_3 with ErrorStatus::NONE. If the asynchronous task
+     * fails to launch, prepareModelFromCache_1_3 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
+     * prepareModelFromCache_1_3. 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 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.
+     *
+     * @param modelCache A vector of handles with each entry holding exactly one
+     *     cache file descriptor for the security-sensitive cache. The length of

+     *     The cache handles will be provided in the same order as with prepareModel_1_3.

+     *     must match the numDataCache returned from getNumberOfCacheFilesNeeded.
+     *     The cache handles will be provided in the same order as with prepareModel_1_3.
+     * @param token A caching token of length Constant::BYTE_SIZE_OF_CACHE_TOKEN
