- 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.
- Say Y here to enable Intel(R) Trace Hub controller support.

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

- help
- Global Trace Hub (GTH) is the central component of the
- Intel TH infrastructure and acts as a switch for source

- Intel TH subdevices to initialize.
- Say Y here to enable GTH subdevice of Intel(R) Trace Hub.
