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).
    - util — utilities for the default implementation.
  - 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 — code that wraps the legacy API (from hardware/libhardware).
    - util — utilities for the default implementation.
  - vts VTS tests for the effect HIDL API.
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.
