| * DO NOT MERGE - audio flinger: fix fuzz test crashEric Laurent2015-08-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Clear output stream pointer in duplicating thread when the main output to which it is attached is closed. Also do not forward master mute and volume commands to duplicating threads as this is not applicable. Also fix logic in AudioFlinger::primaryPlaybackThread_l() that could accidentally return a duplicating thread. This never happens because the primary thread is always first in the list. Bug: 20731946. Change-Id: Ic8869699836920351b23d09544c50a258d3fb585 (cherry picked from commit f6870aefc5e31d4220f3778c4e79ff34a61f48ad)
* | audioflinger: pause HW A/V sync output when AudioTrack underrunsEric Laurent2014-12-191-0/+3
| | | | | | | | | | | | | | | | | | Do not standby, starve or feed 0s to the audio HAL on direct output using HW A/V sync mode. Bug: 17883772. Change-Id: I11e6c97ec24360d75f9b602814d40a54b60cb7a7
* | audioflinger: implement pause/resume for direct outputsEric Laurent2014-12-161-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend pause/resume support to direct output threads (was only for offload threads). If the HAL implements pause/resume, track pause/resume is forwarded to the HAL. Pause, flush, resume sequence is respected by executing the HAL calls in the playback thread (same as offload). Make sure the track flags on client side are consistent with the flags on server side. Bug: 17883772. Change-Id: I89b360d69818f7a9204bd36e3ec63a79e106ecf1
* | audio: new routing strategies and stream typesEric Laurent2014-11-211-3/+1
|/ | | | | | | | | | | | | 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: forward flush to direct output streamsEric Laurent2014-09-291-3/+2
|/ | | | | | | | Track flush should be forwarded to the audio HAL when playing on a direct output stream. Bug: 17704953. Change-Id: Iafc94327fe9aebf1d4eaa97b76c6767b7ac5babe
* audioflinger: fix pre processing effect leakEric Laurent2014-09-151-3/+0
| | | | | | | | | | | | | | | | | | | | 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 Laurent2014-07-241-1/+14
| | | | | | | | | | | | | | | | | | 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. Bug: 14815883. Change-Id: Ib9515fcda864610458a4bc81fa8f59096ff4d7db

* audioflinger: first patch panel implementation.Eric Laurent2014-05-271-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Laurent2014-05-131-15/+4
| | | | | | | | | | | | | 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.

* audioflinger: refactor thread config eventsEric Laurent2014-05-091-57/+114
| | | | | | | | | | | 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.
