2019-02-18pcm plugs: rework the alsa config cleanupThierry Bultel8-30/+50
The alsa config (for softvol, routes, rate conversion ...) was cleaned up by the owner stream or zone, at their deletion time. This was a mistake, because when the stream or zone creation was not complete, the cleanup of the configuration was not done. Instead of doing that, the config is attached to the plug objects as private data (in the AlsaPcmCtlT structure). Since the AlsaPcmCtlT are always recorded in the creation transaction, it is easy to call the cleaning callback (when it exists) when the transaction is deleted.

2019-02-18alsa-api-pcm: added an 'optional' parameterThierry Bultel3-5/+41
This adds a boolean 'optional' parameter for both playback and capture devices. When the device is not detected, the stream(s) that use is are not created, without leading to the exit of the softmixer.

2019-02-18alsa-transaction: simplify the cleanupThierry Bultel4-40/+38
This simplifies the invocation of cleanup, by only using AlsaMixerTransactionDelete that performs the 3 actions of cleanup, removal from list, and memory freeing. Fixes a bug at MixerExit, because the first transaction was not removed from the list and led to a double free error. Also added a boolean parameter to AlsaMixerTransactionObjectDelete (was AlsaMixerTransactionObjectForget before), that decides wether or not the found object must be destroyed with its destructor (for most of the cases) or simply freed in memory (which is needed for loop device).

Leverage the new AVIRT driver for a more secure, more dynamically configurable loopback sound driver. To use, replace the file smixer-4a-default.json with smixer-4a-avirt.json, at /usr/libexec/agl/smixer/etc. The snd-avirt drivers are installed in AGL by default as of 6.99.2.

2019-01-16bluetooth sco: fixed the softvol open errorThierry Bultel3-3/+5
This fixes #SPEC-2125. The fix consists in specifying the number of channels in the softvol pcm configuration. When it is not set, the libasound detects a configuration mismatch (the default number of channels being 2), and attempts to remove the sotfvol control, which for unknown reason, (broken support on kernel side ?) randomly fails.

2019-01-03bluetooth: fixes the cleanup at SCO hangupThierry Bultel1-6/+0
A bug in bluez-alsa was preventing to perform the PCM close, it was leading to a crash. There is a fix for this already, in bluez-alsa (as a patch in meta-agl-devel: https://gerrit.automotivelinux.org/gerrit/#/c/19365), that allows to get rid of the current limitation (4a had to be restarted between 2 phone calls). Now that the fix is available, (even if it is still no mainlined), it is now safe to perform the PCM close, without having a a crash.

2018-12-22Implemented the bug cleanup at application exitStephane Desneux15-132/+312
Fixes most memory leaks in softmixer. The concept of 'transaction' for dynamic streams has been generalized to the objects created at startup. The cleanup is done via a handle set through a atexit() call. Also added a missing strdup in alsa-api-loop, that fixes a double free. Warning, the bluez-alsa PCM are not closed in this version. This is intentional due to a BUG in the bluealsa ioplug PCM, that crashes upon close (pthread_cancel is used to terminate the io_thread and things get very bad. I have a pending fix for that, relying on a cancellation pipe, but deeper testing must be done). As an effect, only one phone call can be made, else 4a needs to be restarted Change-Id: Idb84cafe15f17c0ef02fcc70296d541dc55a2dcf Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh> Signed-off-by: Stephane Desneux <stephane.desneux@iot.bzh>
2018-12-19Add support for bluetooth telephonyguppy_6.99.3guppy/6.99.36.99.3Thierry Bultel24-1056/+2166
This adds support for bluetooth telephony. A big rework in the softmixer internals has been mandatory, in order to support dynamic streams creation and deletions. Bluetooth telephony relies on the recent evolutions of bluez-alsa, the most important one being the support of HFP over Ofono. The softmixer opens PCM ioplugs provided by bluez-alsa. Bluetooth SCO needs 2 streams, one for listening and the other for talking. These streams are created upon requests sent by the hal-manager. The hal manager subscribes for bluez-alsa events and request the list of availalble transports. For each "attach" transaction verb, the softmixer maintains a list of the all created objects (sources, sinks, zones, ramps, streams, and more) Additionnally, it creates a new verb when the attach succeeds, that verb is typically something like "sco_XX:XX:XX:XX:XX:XX", and the only supported action at the present time is {"action":"remove"}, that performs all the cleanup of the registered objects.

2018-08-31Added bluez sound playback supportThierry Bultel13-57/+271
This adds sound playback for incoming sound from connected bluetooth devices. In this version, the softmixer relies on a modified bluez-alsa version (https://github.com/iotbzh/bluez-alsa), that provides an ioplug PCM bluezalsa connection proxy. The softmixer api has a new verb to dynamically set the device to listen to: afb-client-demo ws://localhost:1234/api?token=\uuid=123 smixer bluezalsa_dev '{"interface":"hci0", "device":"F6:32:15:2A:80:70", "profile":"a2dp"}' In this way it is possible to switch from a bluezalsa audio source to another without any further configuration. For now, only interface hci0 is supported. This commit also migrates the softmixer binding to API v3 Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>

2018-07-20rework the sound capture & playback modelThierry Bultel4-254/+324
Now uses two threads for in the playing loop The first one reads from the capture device (ie, a phys. capture, or snd_aloop) and writes data to a circular buffer. The second one gets data from the circular buffer and outputs it to the playback. This model solves a lot of correlated timing bugs between read & write tasks. The read tasks only wakes up the write task when the buffer is 80% full. The buffer size big enough to hold 2 seconds of sound. The mute implementation has also been simplified, since it has been found out that it was possible to recover from an interrupted read, by calling snd_pcm_start additionnally to snd_pcm_prepare. Thus, the mute code consists in listening to an extra file descriptor in the read loop. Reading from that descriptor gives the mute or unmute command sent at higher level (in the PCM control event callback). When a 'mute' order is get, the capture sound fd is simply backup and replaced by '-1' in the set of the poll of the read task. When a 'unmute' order is get, the fd is simply restored. The start threshold is only computed for capture, and hardcoded to 1 for playback. This removes most of the remaining EPIPE on playback. The stop threshold has been removed. It had bad side effects on the amount of writeable data returned by snd_pcm_avail_update (was returning too small chunks) Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>

2018-07-11stops the read/write loop when the stream is mutedThierry Bultel9-109/+295
when the stream is muted (due to the configuration, or due to a HAL request), the read/write loop is stopped. The benefit is that muting will work with capture devices that do not implement the mute in their driver. The inconvenient of stopping the read loop is that it has made appear an unexpected side-effect: the poll on capture does not trig for further incoming frames. The workaround is to completely close, then reopen and configure the capture PCM. Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
