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_PCI
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.
config INTEL_TH_PTI
tristate "Intel(R) Trace Hub PTI output"
help
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.
config INTEL_TH_DEBUG
bool "Intel(R) Trace Hub debugging"
depends on DEBUG_FS
help
Say Y here to enable debugging.
