Implement per channel volume on channelmix. Extend control on stream to
take an array of values when possible.
Remove name argument from pw_node_new and pw_device_new. We can pass
this as a property instead.
Improve properties on nodes to more closely match what pulseaudio does.
Don't let the monitor do too much with the udev properties but let the
session manager set the description and icon-names.
Remove some change_mask flags for things that don't change in
introspect. Use the flags to mark changes in -cli and -monitor.
Don't free the buffers when the mix is released, this will happen
when nothing is using them anymore with port_use_buffers later.
Mark a mixer as having buffers when the output port has buffers.
Don't set buffers on a mixer port that already has buffers.
Remove the node buffers reply again. We don't need it. Instead add a
new method to the client-node to upload an array of buffer datas.
This method is called after the client has allocated buffer mem. It
will update the buffers on the server side with the client allocated
memory.
Wait for the async reply of use_buffers when doing alloc_buffers so
that we can get the updated buffer mem before we continue.
Let the link follow the states of the ports.
Add some error code to the port error states.
Add PW_STREAM_FLAG_ALLOC_BUFFERS flag to make the client alloc buffer
memory.
Remove the CAN_USE_BUFFERS flag, it is redundant. We can know this
because of the IO params and buffer params.
Add flags to the port_use_buffer call. We also want this call to
replace port_alloc_buffer. Together with a new result event we can
ask the node to (a)synchronously fill up the buffer data for us. This
is part of a plan to let remote nodes provide buffer data.
Add a tag field when creating a memmap so that we can do lookup on it.
This makes it easier to implement the tracking of mappings for io areas.
Remove custom io memory tracking and use the tags.
Add flags to spa_chunk to make data corrupted. The flags on the buffer
stay constant for the life of the buffer. Add flags to mark memory
readable and writable. Mark memory readonly in v4l2-source.
Pass the daemon activation area to the client in the transport event.
This never changes and need to be handled differently from the other
activation areas.
Use the right flags when importing memory.
Add the (desired) memory type to mempool_alloc.
improve some debug.
Track memory on buffers in the server and simplify some memory tracking
on the client.
Don't send internal memblock flags to client.
Add read/write flags to memblock.
Add a memory pool to manage blocks of memory. Make it possible
to allocate and import blocks.
Add add_mem and remove_mem to the core events to signal a client
of a block of memory. Remove the client-node add_mem.
Make a global pool for memory and a per client pool where we
import and share the memory we need with the client.
Use the new memory pool to track and map memory in clients.
Move the epoll functions to the system functions and make the loop
use those. Use simple mask for events instead of enum.
Add the used system api in pw_loop.
Add System API to spa_support and use it where possible.
Pass the system API used in the realtime loops in spa_support as
well and use this in the realtime paths.
Improve bootstrapping, load only the log and cpu interfaces because
those can/need to be shared between instances. Let the core load
the other interfaces.
Add keys to configure the System and Loop implementations used in
pw_loop.
Remove override for resources, it can't work in general.
Rename method to add_object_listener to add a listener for
events/methods from the remote object.
Rename some methods to _call to call the interface and _notify
to notify the listeners.
Remove unused client event to be notified of resource
implementations.
The interface struct has the type,version and methods of the
interface.
Make spa interfaces extend from spa_interface and make a
separate structure for the methods.
Pass a generic void* as the first argument of methods, like
we don in PipeWire.
Bundle the methods + implementation in a versioned inteface
and use that to invoke methods. This way we can do version
checks on the methods.
Make resource and proxy interfaces that we can can call. We
can then make the core interfaces independent on proxy/resource and
hide them in the lower layers.
Add add_listener method to methods of core interfaces, just
like SPA.
Make a get node method that binds to the server side node of the
client-node immediately. use this in the remote_export and always
return a node proxy.
Use the node proxy to get property updates and signal those in the
stream.
Output controls can be linked to many input controls and many input
controls can receive input from many output controls. Keep the control
link information inside the link.
Just prepare the output on the port and signal ready. When the graph
completes we will be signaled again to recycle the buffer and
prepare more output if we can.
Improve the bookkeeping a little when activating nodes.
Fix race with moving nodes between drivers.
Simplify the scheduling by using simple lists and removing the
subgraphs etc..
Make the driver node trigger all nodes it manages and when they
complete, trigger the driver node to finish the graph.
Pass the complete spa_node_info to update node information. Remove
the redundant max/min port info.
Update the remote node based on port and node update events.
