Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
|

|
|
produce, switch and output trace data from multiple hardware and
|
||
|
|
software sources over several types of trace output ports encoded
|

in System Trace Protocol (MIPI STPv2) and is intended to perform

full system debugging.
