Mikhail Naganov 0e128dd3fe audio: Fix handling of external devices disconnection A mix port can be patched to multiple connected device ports. Thus, when disconnecting an external device and removing the connected port, the profiles of the mix port can only be cleared iff there are no more connected device ports patched to it, and it did not have profiles prior to connection of the first device. Enhanced VTS tests to catch this problem in the HAL implementations. Also, ensure that audio ports and audio routes do not change after the test finishes. This ensures that tests can't affect each other.

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.
