2019-02-18pcm plugs: rework the alsa config cleanupThierry Bultel1-2/+10
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.

- Replace controller binder functions definition with the binder ones. and remove the last used submodules to use the separated libraries. - Add liburcu as a project dependency in addition to the others ones.

2018-12-22Implemented the bug cleanup at application exitStephane Desneux1-1/+1
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 Bultel1-7/+19
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.
