 Directory structure of the audio HAL related code.
 
-## Directory Structure for AIDL audio HAL
+Run `common/all-versions/copyHAL.sh` to create a new version of the audio HAL
+based on an existing one.
 
-The AIDL version is located inside `aidl` directory. The tree below explains
-the role of each subdirectory:
-
-* `aidl_api` — snapshots of the API created each Android release. Every
-  release, the current version of the API becomes "frozen" and gets assigned
-  the next version number. If the API needs further modifications, they are
-  made on the "current" version. After making modifications, run
-  `m <package name>-update-api` to update the snapshot of the "current"
-  version.
-* `android/hardware/audio/common` — data structures and interfaces shared
-  between various HALs: BT HAL, core and effects audio HALs.
-* `android/hardware/audio/core` — data structures and interfaces of the
-  core audio HAL.
-* `default` — the default, reference implementation of the audio HAL service.
-* `vts` — VTS tests for the AIDL HAL.
-
-## Directory Structure for HIDL audio HAL
-
-Run `common/all-versions/copyHAL.sh` to create a new version of the HIDL audio
-HAL based on an existing one. Note that this isn't possible since Android T
-release. Android U and above uses AIDL audio HAL.
+## Directory Structure
 
 * `2.0` — version 2.0 of the core HIDL API. Note that `.hal` files
   can not be moved into the `core` directory because that would change

+     * 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 extension to add support for getting and setting
+     * vendor defined buffer metadata. 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 writable 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, the token used to access
+     * metadata is defined defined as 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 C struct since it
+     * is passed into a C function. The standard buffer metadata types are NOT
+     * defined as a C enum but instead as an AIDL enum to allow for broader usage across
+     * other HALs and libraries. 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
+     * IMapper versions. For more information see the description of "struct MetadataType".
+     *
+     * ------------ Buffer Metadata Stream ---------------------
+     * The buffer metadata is get and set as a void* buffer. By getting
+     * and setting buffer metadata as a generic buffer, 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.
