| help |
| 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. |

| config INTEL_TH_GTH |
| tristate "Intel(R) Trace Hub Global Trace Hub" |
| help |
| Global Trace Hub (GTH) is the central component of the |
| Intel TH infrastructure and acts as a switch for source |
| and output devices. This driver is required for other |
| Intel TH subdevices to initialize. |
| |
| Say Y here to enable GTH subdevice of Intel(R) Trace Hub. |
