[PATCH BlueZ 1/2] transport: add CIG/CIS/PHY properties, don't show unset QoS properties

[PATCH BlueZ 1/2] transport: add CIG/CIS/PHY properties, don't show unset QoS properties

[Pauli Virtanen]

Add CIG, CIS, and PHY properties to BAP transport.  The other QoS
properties are there, and these may also be useful to clients, e.g.  to
manage CIG/CIS allocation as client.

Hide transport QoS properties when they are not configured.

I don't think D-Bus introspection allows polymorphism of properties,
so either we just use uint16 and limit the maximum delay to 65K or we
have say it is in milliseconds given that in most cases the presets
have the Presentation Delay as a round number.

This should be uint32

How about renaming the property to PresentationDelay in ISO transports?
I think it would clearest to keep it as it is in BAP.

For A2DP changing away from the 1/10 ms unit breaks things.

I'm fine adding these but you could also have used BT_ISO_QOS
socketopt to read it directly from the socket in case you want to use
it on pipewire.

Yes, we can do that once we have the fd.

But if client wants to do CIG+CIS allocation in its SelectProperties,
it needs to know already reserved CIG+CIS. Acquiring the fd moves ASEs
out from qos state, which is not wanted for this.

Also, no Acquire call will return until all CIS in the same CIG have
been connected. To acquire the right transports (only those in the same
CIG), we need to know CIGs of all transports before starting to acquire
any. So we don't have any fds at that point.

Managing that probably should be responsibility of BlueZ, it could
connect all CIS in the same CIG when one of the transports is acquired.
Or, try address it in kernel but maybe that has more constraints.

But I think these properties can be added regardless of the above,
given that they have some uses also otherwise.
