2020-04-10add port connect/add/remove callbacks to CoreAudio backendPaul Davis
2020-04-10add port connect/add/remove callbacks to the ALSA backendPaul Davis
This fixes issues with new ports not (always) appearing in port matrices (and presumably elsewhere too)
2020-04-10ALSA: allow to select different I/O devicesRobin Gareus
This adds a basic support to use multiple sound-cards, currently limited to two devices: In/Out with shared settings. Advanced setups still have to resort to using the ARDOUR_ALSA_EXT environment variable
2020-04-10Fix ALSA slave-device half-duplex modeRobin Gareus
2020-04-10ALSA: ignore systemic MIDI latencies during measurementRobin Gareus
2020-04-09ALSA backend: fix incorrect pointer cast (fixes #7998)Paul Davis
2020-04-08use RCU to manage JACK backend's container of portsPaul Davis

2020-04-07fix CoreAudio backend to use shared_ptrPaul Davis
2020-04-07fix up shared_ptr<> use in JACK backendPaul Davis
2020-04-07use shared_ptr to manage backend port lifetimes (Pulse,ALSA,Dummy,JACK)Paul Davis
JACK is not yet finished. Changes also include minor reformatting and a spelling correction (latecies to latencies)
2020-04-02fix another iterator typePaul Davis
2020-04-02fix iterator typePaul Davis

2020-04-02initial try (not compiled) of PortAudio backend using PortEngineSharedImplPaul Davis
2020-04-02use PortEngineSharedImpl with PulseAudio backendPaul Davis
2020-04-02use PortEngineSharedImpl with DummyAudioBackendPaul Davis
2020-04-02buildable version of CoreAudio backend using PortEngineSharedImplPaul Davis
2020-04-02tentative changes to extend port engine shared impl to coreaudioPaul Davis
2020-04-02use new PortEngineSharedImpl in AlsaAudioBackendPaul Davis
2020-04-02add RCU to manage _ports and _portmap in AlsaAudioBackendPaul Davis
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.

2020-03-30Remove duplicate callsRobin Gareus
2020-03-30Tweak engine startup, initial silenceRobin Gareus
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.
2020-03-29Set thread-names (libs)Robin Gareus
2020-03-28ALSA backend: try to recover from poll errorsRobin Gareus
When recover() successfully re-initializes the device, processing can continue just like after an x-run. This can happen during initial session load of "expensive" sessions (in particular on slow systems, e.g. Raspberry Pi) usually with synths. Worker thread pulls in many external files in the background which blocks the bus for a long time. resulting in a poll-timeout.

2020-01-25Downgrade "using all channels" warning to info - part 2Robin Gareus
2020-01-25Explicitly use OSXRobin Gareus
Previously this was inherited via PBD. On MacOS/X, this adds "-undefined dynamic_lookup -flat_namespace" and various "-framework .." options to linkflags Without this flag, .dylibs fail to link usually because of missing `-lintl` (Undefined symbols: "_libintl_dgettext") On other systems this is a NO-OP: CFLAGS_OSX, CXXFLAGS_OSX and LINKFLAGS_OSX are only set on the darwin platform.

2020-01-12Fix thinko in eee01188 (engine pulse spacing)Robin Gareus
2020-01-06Dummy: Engine-Pulse audio/midi generatorsRobin Gareus
This produces synchronous events on Audio and MIDI ports. One rvent per second, exactly at every second since engine-start. MIDI: C-4 Note-on/off (1 sample long) Audio: +1/-1 transition: +1 in sync with Note-on, -1 in sync with Note-off

2019-09-18NO-OP: fix some Wimplicit-fallthroughRobin Gareus
gcc can recognize various regexps in comments. Since C++17 provides [[fallthrough]], using /* fallthrough */ consistently seems appropriate until we switch to C++17. see also https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
