* DO NOT MERGE - improve audio effect framwework thread safetyEric Laurent2017-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | - Reorganize handle effect creation code to make sure the effect engine is created with both thread and effect chain mutex held. - Reorganize handle disconnect code to make sure the effect engine is released with both thread and effect chain mutex held. - Protect IEffect interface methods in EffectHande with a Mutex. - Only pin effect if the session was acquired first. - Do not use strong pointer to EffectModule in EffectHandles: only the EffectChain has a single strong reference to the EffectModule.

* audio: several fixes in audio routing callbacksEric Laurent2015-07-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | - audio policy: Force device change to ensure new audio patch creation upon first track activity on a given output. Fix function device_distinguishes_on_address() which could mistake some output device with remote submix input device. - audio flinger: Reduce number of binder calls upon new client registration by only sending ioConfigChanged() callbacks to newly registered client. Fix first patch after output thread creation not triggering an ioConfigChanged() callback. -audio system: Force client registration upon routing callback installation to force new ioConfigChanged() callback from audio flinger.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clean up implementation of audio configuration cache and callback events from AudioFlinger: - Define class AudioIoDescriptor for audio input and output configurations outside of AudioSystem class. - Do not use void * but an AudioIoDescriptor as argument to audio config callbacks from AudioFlinger. - Remove unused configuration events. - Move AudioSystem audio input and output cache from static singletons to members of AudioFlingerClient subclass.

| * PatchPanel: do not use setParameters() internally.Eric Laurent2015-04-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not use setParameters() with AUDIO_PARAMETER_STREAM_ROUTING when communicating the input or output device selected to playback or record threads, even for HAL version less than 3.0. Use createAudioPatch()/releaseAudioPatch() instead. This allows to send more information on the output or input device being selected. Also fix a regression introduced in L where the output device selection was not communicated to effects on record threads. Change-Id: I4780ada53241d56694b005c992171e173c3bf8f5

* 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.

* 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.

| | | | | | | | | | | | | | | | | | 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

* | 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.
