Use the port_set_mix_info to add and remove mix info information to the
client.
Previously it was impossible to clean up mix_info.
With this change we can also simplify the jack peer port detection.
Because the mix info is always sent before the link appears we can
simply look up the info when the link appears.
The rt.mix_lst is really something internal to the tee and fallback
mixer in the ports so make it private.
Use the port_set_io call to add the Buffer io area to the mix_list
tee and fallback mixer on the port, like we do for remote-node. We can
then remove the custom code to do this in remote-node and impl-link.
Remove an unused field (clock) in the port struct.
Remove the unused io_set field in impl-link, it is always in sync with
the activated field.
Add a flag to the activation to mark the node as being profiled.
Only wake up the eventfd in remote-node when the profiler is running.
This keeps the server sleeping when remote nodes are driving and the
profiler is not running.
Make a copy of the node name into a statically allocated array. This is
for debugging purposes only but might crash if we do a name change while
the data thread is reading it.
Make it possible to do reposition on the client side by copying the id
to the target. The client side does not have a node in the target so we
can't deref it.
For remote nodes, set the signal time before we wake up the server. For
non-remote nodes, ser the signal time in node_ready. This ensures we
take the time to start the graph into account.
Add a _fast callback function that skips the version and method check.
We can use this in places where performance is critical when we do the
check out of the critical loops.
Make all system methods _fast calls. We expect them to exist and have
the right version. If we add new versions we can make them slow.
Let the server calculate signal time when it starts the graph. Otherwise
we overwrite old values and we can't do stats.
We might be able to piggyback the signal time in the prev_signal_time
field later.
Don't make an extra eventfd for activating the remote-node, we can
use the server side eventfd and send them to the remote side using
the transport.
The remote node already adds the eventfd to the data-loop so avoids
doing the same on the server.
This makes driver nodes trigger all remote nodes directly instead of
going through an intermediate eventfd. For resuming nodes, we already
used the node eventfd directly so this only a small optimization
for the initial cycle start.
For client-nodes that use trigger, set the signal and wakeup time when
they start the server node. Also set finish time before we resume the
peers on the server.
Client-nodes should really resume the peers directly without going
through the server but this is something to improve later.
Calculate the stats at the start of the new cycle. The results will be
about the previous cycle but this gives more accurate results because
we can also include awake and finish times of remote nodes.
Make sure not to change the status of the activation in the ready event
so that we don't overwrite the status of the last cycle yet.
This means we can always set the AWAKE and awake_time, the remote node
might update it when triggered but that's ok.
After processing we can update the FINISHED state for non-remote nodes,
the remote nodes will update it after they complete the process
function.
Pass the ready status to the client-node using the state array.
Don't just SPA_STATUS_HAVE_DATA on the server side but use the value
from the client.
This avoids some potential extra work when a driver sink pulls in data
with the NEED_DATA ready callback but then the server performs the
actions (tee) as if it were SPA_STATUS_HAVE_DATA.
this event extends the bound_id event and sends the global properties as
well.
This can be used to get the object.serial, for example.
It can also be used in the future to let the server generate unique
property values, like the node.name, and let the client know about the
new property value.
For now, put a limit on the amount of items we can send and receive
over the native protocol. A more complex way of allocating and freeing
can be implemented later when we really need to raise the limits.
Fixes#2070
When the memory is removed, clear the node io areas so that it doesn't
accidentally get reused.
Fixes a crash in cheese when the node is stopped and then resumed.
Add a new object.register boolean property.
Make adapter and remote-note only register when object.register
is true.
Make stream and filter not register themselves. They are always
exported to a remote server and thus don't need local
registration.
Fixes#1309
This also brings the advantage that all tools, examples, modules, components
can also be compiled standalone out-of-tree using libpipewire from the system
Make structure with defaults that holds the defaults as they are loaded
from the config file or initialized with default values.
Copy this structure to a settings version that is used at runtime.
Add a force-quantum and force-rate field in the settings that can be
used to force a quantum and samplerate if != 0.
