2019-05-13loops/avirt: forget saved loops after creationsandbox/tbultel/spec-2387Thierry Bultel2-6/+11
avirt needs a backup of loops, before creating the streams. However, this breaks software dynamic streams such as those of of type bluez-alsa, because the logic was re-calling the loop creation at each call of the 'attach' verb. The fix simply consists in forgetting the saved loops once they are created Bug-AGL: SPEC-2387 Change-Id: I63f492b89233bed12de583de6e1077ac1c9c3ccf Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>

2019-05-13core-pcm: fixed channels setting issuesThierry Bultel2-13/+24
Recent tries on the minnow board have show that the setting of channels on a PCM must be done -after- the setting of the rate. When not doing that, there can be issues (really, complicated to find) around the boundaries values (open intervals) on the period bytes. Additionally, the number of channels can now be forced in the json file. Change-Id: I2c20853daadf9ccab06be6e04d1a185440f57780 Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2019-05-13core pcm: use the same model for writing and reading audioThierry Bultel2-67/+177
Reading sound frames relies on usage of poll before calling snd_pcm_writei Recent seeks for bugs and CPU load issues have shown that the same thing must be done on the write side. Thus this commit uses the same mechanism, including the dedicated event pipe for the thread termination.

2019-05-13pcm 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.

2019-05-13alsa-transaction: simplify the cleanupThierry Bultel4-39/+36
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).

2019-04-09Updates for latest libavirt, adds avirt cleanupguppy_7.0.1guppy/7.0.17.0.1Mark Farrugia3-3/+30
Cleanup for avirt is introduced. There are still some issues with this when invoked whilst a PCM is active, This now allows 4A to be restarted without a reboot. Loops must be deleted last to avoid any cleanup issues, so to enforce this a new transaction API is added: AlsaMixerTransactionObjectAddTail.

2019-04-05Fix a SIGSEGV during initializationJosé Bollo1-10/+8
During the initialisation of 4a-softmixer, when the function 'ProcessOneAvirtSubdev' fails, the function 'AttachOneLoop' was crashing because it tried to call 'snd_ctl_close' with a NULL pointer. This change fixes it. A test is introduced because depending on the kind of loop, the order of initialization of control versus subdevs differs. At the same time, some gotos are improved to avoid a dummy test -this are also virtual fixes-. Also a tiny refactor of the 3 times declared variable 'subdev' is expected to improve the readability.

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 Bultel10-42/+254
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 Bultel8-107/+286
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>
