fix volume and effect enable delay on offloaded tracks Volume: add a method to wake up the mediaserver playback thread when a volume command is received on an offloaded track. Effects: call effect chain process on offloaded playback threads asynchronously from writes to allow effect state updates while waiting for async write callback. Bug: 10796540.

more support for audio effect offload Offloading of audio effects is now enabled for offloaded output threads. If an effect not supporting offload is enabled, the AudioTrack is invalidated so that it can be recreated in PCM mode. Fix some issues in effect proxy related to handling of effect commands to offloaded and non offloaded effects. Also fixed a bug on capture index in software Visualizer effect. Bug: 8174034.

audioflinger: no effects on offloaded tracks Invalidate offloaded tracks when an effect is enabled so that the track is recreated in PCM mode and the effect can be applied. This is temporary until effect offloading is implemented. Bug: 8174034. Change-Id: I77b8b54a10db6cb8334be76d863ea7e720eaad09

AudioFlinger: offload playback, non-blocking write - Added specialized playback thread class for offload playback, derived from directoutput thread. This thread type handles specific state transitions for offloaded tracks and offloading commands (pause/resume/drain/flush..) to audio HAL. As opposed to other threads, does not go to standby if the track is paused. - Added support for asynchronous write and drain operations at audio HAL. Use a thread to handle async callback events from HAL: this avoids locking playback thread mutex when executing the callback and cause deadlocks when calling audio HAL functions with the playback thread mutex locked. - Better accouting for track activity: call start/stop and release Output methods in audio policy manager when tracks are actually added and removed from the active tracks list. Added a command thread in audio policy service to handle stop/release commands asynchronously and avoid deadlocks with playback thread. - Track terminated status is not a state anymore. This condition is othogonal to state to permitted state transitions while terminated. Change-Id: Id157f4b3277620568d8eace7535d9186602564de

AudioFlinger: do not cache audio device when 0. AudioFlinger should not cache the audio device passed to the audio HAL when it is AUDIO_DEVICE_NONE but keep previous valid selection instead. Bug: 9323399. Change-Id: I6f9480e55a21be4115453e6a5eebc5cf2536c476

AudioFlinger files reorganization Audioflinger.cpp and Audioflinger.h files must be split to improve readability and maintainability. This CL splits the files as follows: AudioFlinger.cpp split into: - AudioFlinger.cpp: implementation of IAudioflinger interface and global methods - AFThreads.cpp: implementation of ThreadBase, PlaybackThread, MixerThread, DuplicatingThread, DirectOutputThread and RecordThread. - AFTracks.cpp: implementation of TrackBase, Track, TimedTrack, OutputTrack, RecordTrack, TrackHandle and RecordHandle. - AFEffects.cpp: implementation of EffectModule, EffectChain and EffectHandle. AudioFlinger.h is modified by inline inclusion of header files containing the declaration of complex inner classes: - AFThreads.h: ThreadBase, PlaybackThread, MixerThread, DuplicatingThread, DirectOutputThread and RecordThread - AFEffects.h: EffectModule, EffectChain and EffectHandle AFThreads.h includes the follownig headers inline: - AFTrackBase.h: TrackBase - AFPlaybackTracks: Track, TimedTrack, OutputTrack - AFRecordTracks: RecordTrack Change-Id: I512ebc3a51813ab7a4afccc9a538b18125165c4c
