78a66b7180 improved port cleanup as backend is destroyed 2020-04-07 23:26:51 -06:00
b9cb306e8b use shared_ptr to manage backend port lifetimes (Pulse,ALSA,Dummy,JACK)
JACK is not yet finished.

Changes also include minor reformatting and a spelling correction (latecies to latencies)

6c2e30b790 use new PortEngineSharedImpl in AlsaAudioBackend 2020-04-02 19:45:31 -06:00
9ac0d5b60f add RCU to manage _ports and _portmap in AlsaAudioBackend
This is intended to prevent crashes when unregister_port() modifies the contents of these
two members at the same time that something else is iterating over them.

Reset DSP load on backend re-start and after freewheeling 2020-03-30 16:58:55 +02:00

Tweak engine startup, initial silence
This can help when running with very low latency and the
initial process callback is [indirectly] expensive.

E.g. load a heavy session the a RPi4, initial setup can pull
in a lot of data, which blocks the bus.

In particular with the ALSA backend this can lead to poll timeout
which effectively stops the backend.

Prefix all env variable with "ARDOUR_"
In particular "CONCURRENCY" can be problematic. But in general
it's good practice to use a namespace prefix for app-specifics.

ALSA: add locks to safely add/remove MIDI devices
Theoretically this could be lock-free by using a queue of device
ports to be added/remove in sync in the process-callback, but
realistically adding/removing devices doesn't have to be rt-safe.

ab3889fff8 Propagate Latency to backend/system ports
Set accumulated capture-latency for physical-outputs

after Ardour is done setting all non-physical port latencies.

This will be needed for latency-compensation of the complete graph.

dcf327f86a Return meaningful error codes when ALSA backend fails to start
Unfortunately it seems that in zita-alsa-pcmi doesn't set state() correctly in
some cases. Setting an invalid SR doesn't display the correct error message,
first guess would be that set_hwpar is failing and state() is not
representative of the actual error.
