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. | |
11 | ||
12 | This option enables intel_th bus and common code used by TH | |
13 | subdevices to interact with each other and hardware and for | |
14 | platform glue layers to drive Intel TH devices. | |

33 | Intel(R) Trace Hub may exist as an ACPI device. This option enables | |
34 | support glue layer for ACPI-based Intel TH. This typically implies | |
35 | 'host debugger' mode, that is, the trace configuration and capture | |
36 | is handled by an external debug host and corresponding controls will | |
37 | not be available on the target. | |
