0005 help
0006 Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
0007 produce, switch and output trace data from multiple hardware and
0008 software sources over several types of trace output ports encoded
0009 in System Trace Protocol (MIPI STPv2) and is intended to perform
0010 full system debugging.
