* audio: new routing strategies and stream typesEric Laurent2014-11-211-0/+2
| | | | | | | | | | | | | Added new routing strategies and stream type for internal use by audio policy manager and audio flinger: - One for accessibility to allow different routing than media - One for re-routing (remote submix) in preparation of dynamic policies - Added stream type for "internal" audio flinger tracks used for audio patches and duplication. Bug: 18067208. Change-Id: I88f884b552e51e4a49c29125e5a1204cf58ff434
* audioflinger: new HW A/V sync ID allocation flowEric Laurent2014-10-221-0/+3
| | | | | | | | | | | | | The HW A/V sync ID is now allocated by the audio HAL before the output stream is created by a call to global get_parameters() with key AUDIO_PARAMETER_HW_AV_SYNC. When the AudioTrack is created, the HW A/V sync ID is communicated to the output stream by stream set_parameters() with key AUDIO_PARAMETER_STREAM_HW_AV_SYNC. Bug: 17112525.

* audioflinger: fix pre processing effect leakEric Laurent2014-09-151-0/+20
| | | | | | | | | | | | | | | | | | | | When a capture thread was closed, the effects attached to this thread were left dangling and the associated effect chain destroyed. When their last client was disconnected, the effects were not released properly from the effect library because the destruction process could not be completed without the effect being attached to a thread. A similar problem prevented a RecordTrack to be properly released if its client was destroyed after the capture thread. The fix consists in allowing the effect or record track to be properly released even if its parent thread cannot be promoted. Also save any effect chain still present on a closed capture thread in case a new client wants to reuse the effects on the same session later. Bug: 17110064.

* audio flinger: add patch connection between hw modulesEric Laurent2014-07-241-2/+19
| | | | | | | | | | | | | | | | | | Add support for audio device connections between different audio hw modules. The patch is performed by creating a bridge between the playback thread connected to the sink device and the record thread connected to the source device using a pair of specialized PlaybackTrack and RecordTrack. - Added PatchTrack and PatchRecord classes. - Added TrackBase type to indicate more clearly the track behavior. - A TrackBase can allocate the buffer or reuse an existing one. - Factored some code in openOutput() and openInput() for internal use by PatchPanel.

* audioflinger: first patch panel implementation.Eric Laurent2014-05-271-24/+13
| | | | | | | | | | | | | | | | | | | | | | | | | Added a new PatchPanel subclass to AudioFlinger to handle audio ports and audio patches configuration and connection. The first implementation does not add new functionnality. AudioPolicyManager uses patch panel interface to control device routing. AudioFlinger: - Added PatchPanel class. The first implementation does not add new functionnality. PatchPanel handles routing commands for audio HAL after 3.0 or converts to setParameters for audio HALs before 3.0. - Added config events to ThreadBase to control synchronized audio patch connection. AudioPolicyManager: - Use PatchPanel API to control device selection isntead of setParameters. - New base class AudioPort common to audio device descriptors and input output stream profiles. This class is RefBase and groups attributes common to audio ports. - Use same device selection flow for input as for outputs: getNewInputDevice -> getDeviceForInptusiource -> setInputDevice Change-Id: Idaa5a883b19a45816651c58cac697640dc717cd9

| | | | | | | | | | This will allow (eventually) a greater dynamic range for gains.

* | AudioFlinger: add specific mutex for client listsEric Laurent2014-05-131-9/+8
|/ | | | | | | | | | | | | Add a specific mutex to protect access to mClients and mNotificationClients lists. This avoids locking the main AudioFlinger mutex from inside thread loops and allows not to worry about cross deadlocks when sending a config event with status reply while keeping the ThreadBase or AudioFlinger mutex locked. As a way of consequence, remove notification client list passed to processConfigEvents_l() and audioConfigChanged() as the list can now be accessed by locking client mutex only.

| | | | | | | | | | | | | | | | | | | | | | Merge config events and set parameters messaging mechanism. - setting parameters now uses the config event mechanism - config event now allow to wait for a condition and synchronize caller binder thread with execution thread and return an execution status. - simplify locking mechanism to avoid unlocking the thread mutex while processing events.

* | audioflinger: fix race condition in SyncEvent callbackEric Laurent2014-02-201-4/+4
|/ | | | | | | | | | | | | Now that the SyncEvent callback is implemented by the RecordTrack instead of the RecordThread, there is a possibility that the callback is called after the track deletion. SyncEvent callback now uses a weak pointer instead of a raw pointer as cookie. This allows the callback implementer to acquire a strong reference on the object pointed to by the cookie.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed bug that if the binder call failed (for example if the IAudioFlinger binder is dead), then getInputFramesLost was returning garbage. Now it correctly returns zero, which is the error value for this method. The type declarations for getInputFramesLost were inconsistent: a mixture of unsigned int, size_t, and uint32_t. Now it returns uint32_t everywhere, which is what the underlying HAL API returns. Added a FIXME about the side effect behavior. This will need review for multi-client.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change allows a media.log buffer for RecordThread. Unlike playback threads which stick around forever, the RecordThread comes and goes for every capture session. This means that the media.log buffer for a RecordThread would disappear too, and so was useless. Now when a thread exits, it's associated media.log buffer is just marked for deferred deallocation. It is only actually freed when the memory is needed. Other changes: - Fix bug in unregistering comparison, it was comparing the wrong pointers - Increased size of log area so we can log for RecordThread also Change-Id: If45d4c03a793b86390a0112ec3acc5d41b2e3635
