I am wondering if the UHD driver has the ability to create multiple
copies of the stream in memory???
Let's say I have a flow-graph that has two branches, the first pushes
complex data to an FFT, whereas the second demodulates a portion of
that data into AM.
Does the driver supply a single stream, which is then copied by the
application? Or does it create two copies of the stream and allow
each branch of the flow-graph to manipulate the data via pointers?
I'm digging into DMA to see if this is possible, I would be surprised
if there was a limitation here.

The UHD driver provides a single stream to the Gnu Radio interface.
Any "branching" of that stream is handled by the Gnu Radio scheduler,
and completely outside the control or knowledge of UHD.
