   6           Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
   7           produce, switch and output trace data from multiple hardware and
   8           software sources over several types of trace output ports encoded
   9           in System Trace Protocol (MIPI STPv2) and is intended to perform
  10           full system debugging.

  13           subdevices to interact with each other and hardware and for
