That'd require us to move all the DAPM information for drivers out of the kernel and into userspace which seems a bit worrying - it's going to be harder for things that need events and I worry about the effect on quality of implementation if people stop sending things to get reviewed.
Not for this option, for example in SKL.
kernel doesnt have toplogy information coded in, it is parsed and build from topology binary which is built by alsa-lib. So if we add more alsa-lib APIs to parse the installed binary we have good view of system without going to kernel, we know complete graph and controls...
That's a specific case where the topology definition is coming in with the actual implementation. For CODECs where things are in silicon things are a bit different.
