Output ports share the same buffers on all mix outputs and the buffers
are stored in a special mix area with id SPA_ID_INVALID.
The special mix area does not have the peer_id of the link, we need to
get that from the non-shared mix area.
This fixes some invalid peer port-id values in the set_mix_info event.
Add a new client-node port_set_mix_info event. bump the interface
version to 4 and the event version to 1.
The event is used to send information about the peer object to the
port mixer. This can be used to track what buffers belong to what
peer.
The target signal is called when the peer nodes are ready and this
node needs to be scheduled. It is the in-process version of the
signal.
Remove our custom version that, just like the default version, schedules
the node implementation but doesn't do any accounting.
Makes pw-top report driver stats for bluetooth devices.
Fixes#1450
Mark some structures, arrays static/const at various places.
In some cases this prevents unnecessary initialization
when a function is entered.
All in all, the text segments across all shared
libraries are reduced by about 2 KiB. However,
the total size increases by about 2 KiB as well.
Just like the real free() we should just ignore a NULL pointer, makes the
caller code easier for those instances where properties are optional.
Patch generated with concinelle with a few manual fixes.
SPA_MEMBER is misleading, all we're doing here is pointer+offset and a
type-casting the result. Rename to SPA_PTROFF which is more expressive (and
has the same number of characters so we don't need to re-indent).
Always iterate all params because we are only supposed to
return -ENOENT for unknown params and if we start iterating at some
random start position we might be past the paran and report -ENOENT
wrongly.
When the client uploads a buffer, copy all data fields except for
the chunk memory that we configured before.
If we overwrite the chunk memory, the users of the buffer would not
be able to find the chunk memory anymore and crash or fail.
enum_param should return -ENOENT when the param is not known.
When negotiating buffers handle -ENOENT. This means the port does
not know about the property and we should assume anything is fine
so just use the filter from the first port.
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
The proxy API is the one that we would like to expose for applications
and the other API is used internally when implementing modules or
factories.
The current pw_core object is really a context for all objects so
name it that way. It also makes it possible to rename pw_core_proxy
to pw_proxy later.
