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?
Dan
Interesting question. My product doesn't use QMI. I would expect that
all QMI runs through Router these days, but I am seeing some QMI
channels in the downstream source.
Hemant, Do you know what is the usecase for the QMI0/QMI1 channels?
