What's the user space that talks to this?

Multiple.

Each channel has a different purpose.  There it is expected that a 
different userspace application would be using it.

Hemant implemented the loopback channel, which is a simple channel
that 
just sends you back anything you send it.  Typically this is consumed
by 
a test application.

Diag is a typical channel to be consumed by userspace.  This is
consumed 
by various applications that talk to the remote device for
diagnostic 
information (logs and such).

QMI too?

Sahara is another common channel that is usually used for the
multistage 
firmware loading process.
