5	help
6	  Intel(R) Trace Hub (TH) is a set of hardware blocks (subdevices) that
7	  produce, switch and output trace data from multiple hardware and
8	  software sources over several types of trace output ports encoded
9	  in System Trace Protocol (MIPI STPv2) and is intended to perform
10	  full system debugging.
11
12	  This option enables intel_th bus and common code used by TH
13	  subdevices to interact with each other and hardware and for
14	  platform glue layers to drive Intel TH devices.
15
16	  Say Y here to enable Intel(R) Trace Hub controller support.

21	tristate "Intel(R) Trace Hub PCI controller"
22	depends on PCI
23	help
24	  Intel(R) Trace Hub may exist as a PCI device. This option enables
25	  support glue layer for PCI-based Intel TH.
26
27	  Say Y here to enable PCI Intel TH support.

30	tristate "Intel(R) Trace Hub ACPI controller"
31	depends on ACPI
32	help
33	  Intel(R) Trace Hub may exist as an ACPI device. This option enables
34	  support glue layer for ACPI-based Intel TH. This typically implies
35	  'host debugger' mode, that is, the trace configuration and capture
36	  is handled by an external debug host and corresponding controls will
37	  not be available on the target.
38
39	  Say Y here to enable ACPI Intel TH support.

41config INTEL_TH_GTH
42	tristate "Intel(R) Trace Hub Global Trace Hub"
43	help
44	  Global Trace Hub (GTH) is the central component of the
45	  Intel TH infrastructure and acts as a switch for source
46	  and output devices. This driver is required for other
47	  Intel TH subdevices to initialize.
48
49	  Say Y here to enable GTH subdevice of Intel(R) Trace Hub.

51config INTEL_TH_STH
52	tristate "Intel(R) Trace Hub Software Trace Hub support"
53	depends on STM
54	help
55	  Software Trace Hub (STH) enables trace data from software
56	  trace sources to be sent out via Intel(R) Trace Hub. It
57	  uses stm class device to interface with its sources.
58
59	  Say Y here to enable STH subdevice of Intel(R) Trace Hub.

64	  Memory Storage Unit (MSU) trace output device enables
65	  storing STP traces to system memory. It supports single
66	  and multiblock modes of operation and provides read()
67	  and mmap() access to the collected data.
68
69	  Say Y here to enable MSU output device for Intel TH.

73	help
74	  Parallel Trace Interface unit (PTI) is a trace output device
75	  of Intel TH architecture that facilitates STP trace output via
76	  a PTI port.
77
78	  Say Y to enable PTI output of Intel TH data.
