Mikhail Naganov 57633e5a78 VTSHalAudio: Increase test timeout for V6 and V7 V6 and V7 use actual device audio configuration when testing I/O streams functionality. On low-end TV devices this can cause the test to run for significant time due to lower CPU speed and the amount of multichannel configurations. From testing on real devices, the timeout value of 5 minutes seems to be adequate. Bug: 211945822 Test: atest VtsHalAudioV6_0TargetTest Change-Id: Ie233e014f9f3650f58319c4d5f5a836cfdea87ba		2022-01-21 21:27:34 +00:00

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.
