+config INTEL_TH
+ tristate "Intel(R) Trace Hub controller"
+ depends on HAS_DMA && HAS_IOMEM
+ 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.

+ tristate "Intel(R) Trace Hub PCI controller"
+ depends on PCI
+ help
+ Intel(R) Trace Hub may exist as a PCI device. This option enables
+ support glue layer for PCI-based Intel TH.
+
+ Say Y here to enable PCI Intel TH support.
+
+config INTEL_TH_ACPI
+ 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.
+
+config INTEL_TH_STH
+ tristate "Intel(R) Trace Hub Software Trace Hub support"
+ depends on STM
+ 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.
+
+ Say Y here to enable STH subdevice of Intel(R) Trace Hub.
+
+config INTEL_TH_MSU
+ tristate "Intel(R) Trace Hub Memory Storage Unit"
+ help
+ 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.
+
+ Say Y here to enable MSU output device for Intel TH.
+

+ Parallel Trace Interface unit (PTI) is a trace output device
+ of Intel TH architecture that facilitates STP trace output via
+ a PTI port.
+
+ Say Y to enable PTI output of Intel TH data.
