+# This script is used to update audio policy configuration files
+# to comply with the updated audio_policy_configuration.xsd from V7.0.
+#
+# The main difference is the separator used in lists for attributes.
+# Since the XML Schema Definition standard only allows space to be
+# used as a separator (see https://www.w3.org/TR/xmlschema11-2/#list-datatypes)
+# the previous versions used a regular expression to validate lists
+# in attribute values. E.g. the channel masks were validated using
+# the following regexp: [_A-Z][_A-Z0-9]*(,[_A-Z][_A-Z0-9]*)*
+# This has an obvious drawback of missing typos in the config file.
+#
+# The V7.0 has shifted to defining most of the frequently changed
+# types in the XSD schema only. This allows for verifying all the values
+# in lists, but in order to comply with XML Schema requirements
+# list elements must be separated by space.
+#
+# Since the APM config files typically use include directives,
+# the script must be pointed to the main APM config file and will
+# take care all the included files automatically.
+# If the included file is a shared version from 'frameworks/av',
+# instead of updating it the script checks if there is a newer
+# version with the corresponding name suffix (e.g.
+# 'a2dp_audio_policy_configuration_7_0.xml') and updates the include
+# path instead.

+# Audio HAL
+
+Directory structure of the audio HAL related code.
+
+Run `common/all-versions/copyHAL.sh` to create a new version of the audio HAL
+based on an existing one.
+
+## 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
+  its namespace and include path.
+   - `config` -- the XSD schema for the Audio Policy Manager
+     configuration file.
+* `4.0` -- version 4.0 of the core HIDL API.
+* ...
+* `common` -- common types for audio core and effect HIDL API.
+   - `2.0` -- version 2.0 of the common types HIDL API.
+   - `4.0` -- version 4.0.
+   - ...
+   - `7.0` -- version 7.0.
+      - `example` -- example implementation of the core and effect
+        V7.0 API. It represents a "fake" audio HAL that doesn't
+        actually communicate with hardware.
+   - `all-versions` -- code common to all version of both core and effect API.
+      - `default` -- shared code of the default implementation.
+         - `service` -- vendor HAL service for hosting the default
+           implementation.
+      - `test` -- utilities used by tests.
+      - `util` -- utilities used by both implementation and tests.
+* `core` -- VTS tests and the default implementation of the core API
+  (not HIDL API, it's in `audio/N.M`).
+   - `7.0` -- code specific to version V7.0 of the core HIDL API
+   - `all-versions` -- the code is common between all versions,
+     version-specific parts are enclosed into conditional directives
+     of preprocessor or reside in dedicated files.
+       - `default` -- code that wraps the legacy API (from
+         `hardware/libhardware`).
+       - `vts` VTS tests for the core HIDL API.
+* `effect` -- same for the effect HIDL API.
+   - `2.0`
+      - `config` -- the XSD schema for the Audio Effects configuration
+        file.
+   - `4.0`
+   - ...
+   - `all-versions`
+      - `default`
+      - `vts`
+* `policy` -- Configurable Audio Policy schemes.
+   - `1.0` -- note that versions of CAP are not linked to the versions
+     of audio HAL.
+      - `vts` -- VTS tests for validating actual configuration files.
+      - `xml` -- XSD schemas for CAP configuration files.

- * A channel mask per se only defines the presence or absence of a channel, not

- *
- * The channel order convention is that channels are interleaved in order from

- * followed by RIGHT.
- * Any exceptions to this convention are noted at the appropriate API.
- *
- * AudioChannelMask is an opaque type and its internal layout should not be

- * to examine it.
- *
- * These are the current representations:
- *
- *   REPRESENTATION_POSITION
- *     is a channel mask representation for position assignment.  Each low-order
- *     bit corresponds to the spatial position of a transducer (output), or
- *     interpretation of channel (input).  The user of a channel mask needs to
- *     know the context of whether it is for output or input.  The constants
- *     OUT_* or IN_* apply to the bits portion.  It is not permitted for no bits
- *     to be set.
- *
- *   REPRESENTATION_INDEX
- *     is a channel mask representation for index assignment.  Each low-order
- *     bit corresponds to a selected channel.  There is no platform
- *     interpretation of the various bits.  There is no concept of output or
- *     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
- * is an ambiguity between input and output that is currently resolved by
- * checking the channel mask, the implementer should look for ways to fix it
- * with additional information outside of the mask.
