tristate "Intel(R) Trace Hub controller"
depends on HAS_DMA && HAS_IOMEM
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
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.
tristate "Intel(R) Trace Hub ACPI controller"
depends on ACPI
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.
tristate "Intel(R) Trace Hub Global Trace Hub"
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.
tristate "Intel(R) Trace Hub Software Trace Hub support"
depends on STM
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.
tristate "Intel(R) Trace Hub Memory Storage Unit"
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.
tristate "Intel(R) Trace Hub PTI output"
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.
bool "Intel(R) Trace Hub debugging"
depends on DEBUG_FS
Say Y here to enable debugging.
