bed76798f3 manual fixups after rebase against master (general libs edition) 2021-08-13 12:51:31 -06:00
79763893b3 remove/hide Session::tempo_map() and use TempoMap::use() instead (thread local shared ptr) 2021-08-13 12:51:30 -06:00
f67029bd02 random commit to facilitate trivial move of work from laptop back to main system 2021-08-13 12:51:29 -06:00
f4490f54c5 change Timecode::BBT_Time to use Temporal namespace, plus a couple of other minor changes to enable compilation
This still uses the tempo map object in libs/ardour, not the new one in libs/temporal, and isn't likely to be functional
(though it could be)

ALSA: fix idempotent device name setup
This fixes an edge case where available buffersizes are

ALSA backend: code cleanup and scoping and indent

ALSA: Fix swapped systemic latencies

gcc-11 compat, volatile atomic variables (1/2)
"While 'atomic' has a volatile qualifier, this is a historical
artifact and the pointer passed to it should not be volatile."

Furthermore "It is very important that all accesses to a
particular integer or pointer be performed using only this API"
(from https://developer.gnome.org/glib/2.68/glib-Atomic-Operations.html)

Hence initialization of atomic variables is changed to also use
this API, instead of directly initializing the value.

This also fixes a few cases where atomic variables were
accessed directly.

a2b1482cad Fix a problem with ASIO buffer sizes on Windows
PortAudio uses what it calls 'default suggested latencies' but in callback streaming mode, they can result in wildly inaccurate buffer sizing (e.g. the user requests a buffer size of 128 but PortAudio actually instructs ASIO to use a much bigger size).

What we do now is to improve PortAudio's suggested latency calculation by basing it on the actual buffer size requested by the user.

ALSA: retain port-connections of slave devices
When the engine is re-started, ports should only be reconnected
when all slave devices are running. Previously those connections
were lost.

Prevent deadlock when disconnecting
The backend holds `_port_callback_mutex` while disconnecting ports.
In some cases disconnecting a port can drop the last reference
resulting in a port-deletion from the connection handler.
This in turn will eventually aquire the `_port_callback_mutex`
and deadlock.

This is now circumvented by using atomic operations instead of
taking a lock to set the `_port_change_flag`.

The flag is also used to trigger a latency update in some cases,
atomic is preferable to taking a lock to set this flag.

ALSA: fall back to nearest available buffer-size
The warning "samples per period does not match." never triggered.
Previously not being able to set the requested buffersize was a
fatal error.

This adds support for soundcards that only support msec.

some devices.
