| 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. |

| help |
| Intel(R) Trace Hub may exist as a PCI device. This option enables |
| support glue layer for PCI-based Intel TH. |

| tristate "Intel(R) Trace Hub ACPI controller" |
| depends on ACPI |
| 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. |

| 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. |

| help |
| Software Trace Hub (STH) enables trace data from software |
| trace sources to be sent out via Intel(R) Trace Hub. It |
| uses stm class device to interface with its sources. |

| Memory Storage Unit (MSU) trace output device enables |
| storing STP traces to system memory. It supports single |
| and multiblock modes of operation and provides read() |
| and mmap() access to the collected data. |
