The Trace Hub devices now can be enumerated as ACPI devices, which translates into "Host Debugger mode". There are two IDs: one for PCH Trace Hub, and one for the uncore Trace Hub. These are expected to stay the same across all platforms. Signed-off-by: Alexander Shishkin <alexander.shishkin@linux.intel.com>

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

Intel(R) Trace Hub may exist as an ACPI device. This option enables
